Technical Field

The invention relates to the technical field of plastic master batches and preparation thereof, in particular to a plastic master batch for buildings and a preparation method thereof.

Background

The building plastics are a generic term for plastic products used in construction engineering. The common molding method for manufacturing the building plastic product comprises the following steps: calendering, extrusion, injection, molding, coating, laminating, and the like. The plastic is a material which takes synthetic macromolecular compound or natural macromolecular compound as main base material, is mixed with other raw materials under certain conditions, is plasticized and formed, and can keep the shape of the product unchanged at normal temperature and normal pressure. The plastic has large shaping under certain temperature and pressure, can be easily made into products with various required shapes and sizes, and can keep the obtained shapes and the required strength at normal temperature after being formed.

The variety of the building plastic products is various, and the main types of the building plastic products are as follows:

plastic pipe and pipe fitting

The pipe and joint pipe made of plastic are widely used in indoor drainage, tap water, chemical engineering, wire threading pipe and other pipeline engineering. Common plastics are rigid polyvinyl chloride, polyethylene, polypropylene and ABS plastics (acrylonitrile-butadiene-styrene copolymers). The plastic drain pipe has the main advantages of corrosion resistance and small fluid friction resistance; the impurities flowing through are difficult to adhere to the pipe wall, so the sewage discharge efficiency is high. The plastic pipe is light in weight, is 1/6-1/12 of the weight of the cast iron pipe, can save labor force, and has lower price and construction cost than the cast iron pipe. The disadvantage is that the linear expansion coefficient of the plastic is about 5 times larger than that of cast iron, so a flexible joint needs to be arranged on a longer plastic pipeline. The plastic pipe is mostly manufactured by adopting an extrusion molding method, and the pipe is mostly manufactured by adopting an injection molding method. The plastic pipes are joined by a heat fusion method, a screw joining method, a flange joining method, and a spigot and socket joining method with a rubber seal ring, in addition to an adhesive method. When a pressurized liquid is passed through the polyvinyl chloride pipe, the liquid temperature must not exceed 38 ℃. If the pressure-free pipeline (such as an indoor drainage pipe) is adopted, the temperature of the liquid continuously passing through the pipeline is not higher than 66 ℃; the temperature of the intermittently passed liquid should not exceed 82 ℃. When the polyvinyl chloride plastic is used for a water supply pipeline, toxic stabilizers and other raw materials are not allowed to be used.

Elastic floor

The plastic elastic floor comprises two categories of semi-rigid polyvinyl chloride floor tiles and elastic polyvinyl chloride coiled material floors. The basic size of the floor tile is a square with the side length of 300mm and the thickness of 1.5 mm. The main raw materials are polyvinyl chloride or copolymer of chloroethylene and vinyl acetate, and the fillers are heavy calcium carbonate powder and short fiber asbestos powder. The surface of the product can be provided with a wear-resistant coating, a color pattern or a concave-convex pattern. As stated, the residual concavity of the product must not be greater than 0.15mm, and the abrasion must not be greater than 0.02 mg/cm.

The elastic polyvinyl chloride coiled material floor has the advantages that: the ground has few joints, and is easy to keep clean; the elasticity is good, and the step feeling is comfortable; has good heat insulation and sound absorption performance. The polyvinyl chloride foamed floor with the thickness of 3.5mm and the apparent specific gravity of 0.6 is used in combination with the hollow reinforced concrete floor with the thickness of 120mm, the heat transfer coefficient can be reduced by 15 percent, and the absorbed impact noise can reach 36 decibels. The width of the coiled material floor is 900-2400mm, the thickness is 1.8-3.5mm, and the length of each coil is 20 meters. The common floor board is non-foamed laminated plastic floor board, which has transparent wear resisting layer, lower layer with printed pattern and bottom layer of asbestos paper or glass cloth. For residential construction is a laminated plastic floor with a foamed layer in the middle. The adhesive for adhering plastic floor and floor board includes neoprene latex, polyvinyl acetate latex, epoxy resin, etc.

Carpet made of three kinds of chemical fibre

The carpet is a new product appearing in 1945, the dosage of the carpet is rapidly more than that of a carpet made of traditional raw materials such as wool and the like, and the main materials are nylon filaments, nylon short fibers, acrylonitrile, cellulose, polypropylene and the like. The main performance properties of the carpet are abrasion resistance, elasticity, dirt and stain resistance, easy cleaning, and the difficulty of generating static electricity. The using performance of acrylonitrile, nylon and polypropylene fiber is comparable to that of wool. The chemical fiber carpet has various weaving methods, and the thickness is generally in the range of 4-22 mm. Its main advantages are comfortable feeling, and static electricity, easy dust accumulation and not easy cleaning. Similar to carpet, non-woven carpet also uses chemical fiber as raw material.

Door and window and fittings

In recent 20 years, due to the continuous development of thin-wall hollow profile extrusion process and foaming extrusion process technology, door and window frames, cabinet components and various indoor decoration accessories which are welded by plastic profiles have been remarkably developed and are valued by many countries with shortage of wood and energy. Interior fittings made of rigid foamed polyvinyl chloride or polystyrene are commonly used in the positions of wall corner protectors, caulking strips of door and window openings, caulking strips of gypsum boards, skirting boards, mirror hanging lines, ceiling suspended ceiling return edges, stair handrails and the like. It also has the double functions of building structural parts and artistic ornaments, and can raise the decoration level of building and make the plastic product possess beautiful appearance and easy processing.

Fifthly, wallpaper and veneer

The polyvinyl chloride plastic wallpaper is a high-quality decorative material for decorating indoor walls, and can be made into various beautiful three-dimensional patterns with printing, embossing or foaming. The wallpaper has certain air permeability, flame retardancy and pollution resistance. The surface can be brushed by clean water, and the back surface is provided with a layer of base paper, so that the wallpaper can be conveniently pasted on a smooth wall surface by using various water-soluble glues. Transparent paper impregnated with melamine formaldehyde resin solution is superposed with book cover paper printed with wood grains or other patterns on the surface, and then hot pressed into a hard plastic veneer; or the printing paper soaked with polydiallyl phthalate (DAP) is superposed with medium density fiberboard or other artificial board and hot pressed into decorative board, and the decorative board can be used as indoor partition board, door core board, furniture board or floor.

Sixthly, foamed plastic

A lightweight porous article which is not liable to collapse and which does not lose its heat insulating effect by moisture absorption and is excellent in heat insulation and sound absorption. The product has plate, block or special shape, and can be sprayed on site. Wherein the cells are communicated with each other, so that the foam is called open-cell foam plastic and has better sound absorption and buffering performance; the cells are not communicated with each other, and are called closed-cell foam plastics, so that the thermal conductivity and the water absorption are low. Polyurethane foams, polystyrene foams and urea-formaldehyde foams are commonly used in construction. The polyurethane has the advantages of being capable of foaming by a spraying method in a construction site, having good adhesion with other materials of a wall surface and being resistant to mould corrosion.

Seven, glass fiber

Plastic articles of thermosetting resin reinforced with glass fibers are commonly referred to as glass fiber reinforced plastics. The transparent or semitransparent corrugated tiles, daylighting skylights, bathtubs, integral toilets, foam sandwich plates, ventilation pipelines, concrete formworks and the like are commonly used in buildings. Its advantages are high strength-weight ratio, high anticorrosion and heat-resistant performance, and high electric insulating performance. The thermosetting resin used in the method comprises unsaturated polyester, epoxy resin and phenolic resin. The forming method of the glass fiber reinforced plastic generally adopts hand lay-up forming, spray forming, winding forming and compression forming. The hand pasting forming is that a layer of colored colloidal surface layer is sprayed on the surface of the mould shell, so that the product has beautiful and glossy surface after demoulding. Then, a glass cloth or glass felt layer soaked with the resin mixed solution is manually coated on the colloidal layer, and the demoulding is carried out after the solidification. The spraying method is to use a special spray gun to spray the resin mixed solution and short glass fibers which are cut into 2-3 cm long directly and uniformly on the surface of the mold shell. Although the strength of the glass fiber reinforced plastic is reduced by adopting the short fiber, the production efficiency is high, and the labor force can be saved. The glass fiber reinforced plastic pipe or the tank body is mostly formed by adopting a winding forming method, namely, a glass fiber braided belt or a long glass fiber bundle soaked with resin mixed liquid is wound on a rotating moulding bed according to the stress direction of a product, and the product is formed by demoulding after solidification. Some of the tank bodies are lined with aluminum inner tubes to enhance the sealing performance of the tank bodies. The mould pressing method is that the flaky glass fiber cotton felt or cloth soaked with resin is uniformly overlapped in a mould and is hot-pressed into various finished products, such as a bathtub, a wash basin and the like. The inner surface and the outer surface of the die-pressing product are both provided with beautiful and wear-resistant surface layers, and the production efficiency and the product quality are high. The glass fiber reinforced plastic products for buildings which are rapidly developing comprise cooling water towers, water storage towers, integral assembled toilets, semi-assembled toilets and the like.
