Technical Field

The invention relates to the technical field of penholder manufacturing processes, in particular to a manufacturing material and a manufacturing method of a composite penholder.

Background

With the progress of society, electronic products are more and more, information transmission is more and more transmitted by means of electronics or networks, so that the pen is still an indispensable tool in life though the use is less, anyone depends on the use of the pen in the process of small and big learning and growth, the pen is a tool which is necessary to be used by students in the learning process, the pen is a necessity in life both for writing and for artistic pursuit, the use amount in life is very large, and the corresponding consumption amount is also large.

Although the pen is not a daily consumable product, the using amount is still very large, the pen is a commodity which is relatively easy to be fragile and has low value, the consumption is correspondingly large, most of the manufacturing materials of the pen holder are plastics, cheap general plastics can be adopted for saving the cost, toxic gas is easily released after the plastics are generally heated, the plastics are used as substances which are difficult to be naturally degraded, the waste of resources and the environmental pollution can be caused by continuous production and manufacturing, the manufacturing of the degradable material needs to consume the resources, and the degradation process of the degradable material is also long.

Disclosure of Invention

The invention aims to solve the defects in the prior art, such as: the production of the penholder needs to use a large amount of materials, the plastic material is a material which is difficult to degrade, and the production of the penholder continuously consumes resources and causes environmental pollution at the same time, so that the material and the method for manufacturing the composite penholder are provided.

In order to achieve the purpose, the invention adopts the following technical scheme:

a manufacturing material of a composite pen holder comprises waste plastics and an auxiliary agent, wherein the waste plastics comprise polyethylene terephthalate, high-density polyethylene, polyvinyl chloride, low-density polyethylene, polystyrene, polypropylene, polystyrene and other recyclable plastics; wherein, the polyethylene terephthalate accounts for 8-12 percent, the high-density polyethylene accounts for 13-30 percent, the polyvinyl chloride accounts for 8-12 percent, the low-density polyethylene accounts for 13-30 percent, the polystyrene accounts for 8-12 percent, the polypropylene accounts for 8-12 percent, the polystyrene accounts for 8-12 percent, and the other recyclable plastics account for 8-12 percent by mass percentage.

Preferably, the auxiliary agent comprises a hard additive, a stabilizer, a flame retardant and an antioxidant.

Preferably, the stabilizer is a mixture of calcium stearate and zinc soap, and the hard additive is a resistant inorganic filler. Because the composite material is that multiple raw materials mix together, the composite material after mixing is because various raw materials influence each other, and its melting point can corresponding reduction, in order to guarantee the pen-holder stable in structure after the shaping, adds the stabilizer and increases the hardness, and the mixture toxicity of calcium stearate and zinc soap is little, comparatively safety.

Preferably, the oxidant is formed by compounding red phosphorus, aluminum hydroxide and an expandable graphite inorganic flame retardant. The non-halogen flame retardant has the advantages of small addition amount, high flame retardant efficiency, low smoke, low toxicity, wide application and the like, wherein the physical property of red phosphorus is unstable, and the red phosphorus capsule is wrapped by adopting a microcapsule coating process, so that the red phosphorus capsule is convenient to transport and use and has low smoke, and toxic gas is not generated in the processing process, so that the dispersibility, the physical and mechanical properties, the thermal stability and the flame retardant property of the red phosphorus capsule are improved.

Preferably, the antioxidant is antioxidant 164, and the dosage of the antioxidant is 0.01% -0.5%. As the penholder is an article frequently used by people in daily life, the antioxidant is needed to ensure the stability of the structure of the penholder, and the harm to the human body in the using process is avoided.

A manufacturing method of a composite penholder comprises the following steps:

s1: removing impurities from the recovered waste plastics, cleaning, adsorbing metal parts in the waste plastics by using a magnet during impurity removal, washing the waste plastics after impurity removal with water to remove dirt, and then crushing the waste plastics in a crusher;

s2: spin-drying the crushed materials, and then drying the crushed materials, wherein the drying temperature cannot exceed 60 ℃; when the drying is carried out, the good sealing performance of the equipment is ensured, and the gas generated in the drying process is treated, and the toxic gas can be emitted by heating materials in the waste plastic, so that the drying temperature cannot be too high, the emission of the toxic gas is avoided, if the toxic gas overflows, the environment is prevented from being polluted by the toxic gas at will, and the sealing performance of the drying equipment and a gas treatment device are required to be ensured;

s3: mixing waste plastic particles with an auxiliary agent, performing extrusion molding at the temperature of 150-.

Compared with the prior art, the invention has the beneficial effects that:

1. the recycled waste plastic is used as a raw material for manufacturing, the waste plastic is prepared into a composite material to manufacture the pen holder, the waste plastic which is difficult to degrade is recycled, the environment can be effectively protected, and meanwhile, the cost can be saved by recycling the waste plastic, so that the purpose of reducing the overall cost is achieved.

2. The composite material is made of waste plastic, the penholder is made of the auxiliary agent, the production mode of the raw materials can be produced by oneself, the cost increase caused by the influence of social supply and demand relations can be effectively avoided, the produced penholders are different in color and very characteristic, and the later-stage painting operation is reduced.
