The technical field is as follows:

The invention relates to a method for preparing a rubber brick based on waste rubber as a raw material, and also relates to a method for preparing an environment-friendly water gel based on waste plastics.

Background art:

at present, the ground of sidewalks, bicycle lanes, amusement parks and the like is generally paved with bricks made of cement materials or asphalt-paved asphalt pavements, and the road tooth bricks, blind road bricks and tree maintenance bricks are mainly made of stone materials or cement concrete materials, although the materials are widely applied to road and pavement decoration in the past decades, the road and pavement decoration are all made of rigid materials, on one hand, the road is difficult to avoid damage caused by falling, smashing, collision and bumping during use, the pressure resistance is poor, the service life is greatly shortened, on the other hand, the pavement paved by the rigid materials is hard and inelastic, and people can feel uncomfortable after long walking time, so that the body health is affected. It is therefore imperative to find a comfortable, durable alternative.

with the rapid development of the automobile industry, a large amount of waste tires are produced every day, and as the waste rubber used as a ground decoration material has certain elasticity, can improve the skid resistance, has good attractiveness and comfort, and can be widely used as a good high-polymer environment-friendly material for replacing the existing cement concrete and stone at home and abroad. Rubber as a thermosetting material cannot be directly cast into a desired product shape by heating like a plastic product made of a thermoplastic material, the processing is relatively difficult, and researches on preparing a rubber brick by using waste rubber as a raw material have been reported, for example, a Chinese patent (patent No. 01278118.5) has reported that waste rubber tires are crushed into rubber fine particles, rubber coarse particles and a small amount of granular concrete are added, and a polyurethane adhesive is used as an adhesive for firmly bonding the components together, but the process for preparing the rubber brick by the technology is complicated, and the manufacturing cost of the rubber brick is increased by using the polyester adhesive.

The invention content is as follows:

1. The invention provides a method for preparing a high-strength rubber brick. The rubber brick is composed of environment-friendly water gel and a base material, wherein the environment-friendly water gel is plastic particle emulsion, and is prepared by crushing recyclable plastic into superfine particles, mixing the superfine particles with other substances, and adding the mixture into boiling water.

The base material is rubber particles prepared by mechanically crushing waste tires, waste rubber tubes, leftover materials and other waste rubbers in the rubber production process.

2. The method comprises the following steps: under the vacuum sealing condition, the recyclable plastic is heated and melted and added into the base emulsion to form the environment-friendly water gel.

The recyclable plastic is nylon, polyethylene, polypropylene, polyester or a combination thereof.

The recyclable plastic in the emulsion is nylon, particularly nylon-6.

The recyclable plastic in the emulsion is recycled plastic.

The base emulsion is composed of nylon-6 and other basic components, wherein the basic components comprise caprolactam, methyl ethyl ketone peroxide, triallyl cyanurate, water-soluble wax, polyethylene and acid (such as battery water, sulfuric acid and hydrochloric acid).

The base emulsion prepared by the base component is prepared by heating the base component above the melting temperature of the plastic and sprinkling the plastic powder into the base component.

The preparation of the environment-friendly water gel is to mix heated plastic with substrate emulsion, add the mixture into boiling water, and take the emulsion formed in an emulsifying machine as the environment-friendly water gel.

The preparation of the rubber brick is that rubber particles and environment-friendly water gel are mixed and then are molded by a mold and heated and pressurized.

3. The method for preparing the rubber brick by using the waste concrete comprises the following three steps: (1) crushing the waste rubber in a crusher to obtain regenerated rubber particles; (2) placing the regenerated rubber particles and the environment-friendly water gel into a mixing roll for blending; (3) molding in a mold through a calender or an extruder under the conditions of heating and pressurizing, reducing the temperature to be below the melting point of the plastic, and forming a closely-packed and tightly-combined structure after solidification.

When the die is formed, the use temperature is 140-.

The rubber brick has the characteristics of firmness, durability, skid resistance, high elasticity and the like, can be used as a substitute of stone and concrete bricks of the traditional brick, is particularly suitable for being laid on sidewalks, bicycle tracks, indoor playgrounds, playgrounds and residential fitness and entertainment places, and can also be laid on road surfaces as curbstone bricks, blind road bricks, tree maintenance bricks and the like.

4. The invention provides a preparation method of a rubber brick, which comprises regenerated rubber particles and environment-friendly water cement, wherein the environment-friendly water cement is emulsion containing plastic particles, and the mass fraction of the plastic particles in the rubber brick is less than or equal to 10%.

The mass fraction of the plastic in the rubber brick is 1-5%.

The mass fraction of the environment-friendly water gel in the rubber brick is 5-20%.

The regenerated rubber particles are particles obtained by crushing waste rubber.

The plastic in the environment-friendly water gel is recyclable plastic such as nylon and the like.

The environment-friendly water gel in-emulsion is a mixture of the following substances: (1) methylisothiaimidazolone or methylisothiazolinone; (2) polyethylene, polypropylene, nylon, PVC, expanded polystyrene or acryl; (3) paraffin oil; (4) and (3) water.

The environment-friendly water gel is an emulsion formed by polyethylene, paraffin oil and water.

The environment-friendly water gel is a mixture of methylisothiamidazolidone or methylisothiazolinone, nylon, PVC, foamed polystyrene, polypropylene, acrylic, paraffin oil and water.

The preparation method of the plastic-based environment-friendly water gel comprises the following steps: (1) mixing methylisothiaimidazolone and/or methylisothiazolinone with paraffin oil; (2) melt-adding a plastic to the mixture; (3) and (3) adding the mixture formed in the step (2) into boiling water, and cooling to room temperature for a certain time to obtain the environment-friendly water gel.

In conclusion, the invention provides a preparation method of a rubber brick, which comprises the steps that the base material is recycled plastic particles, the recyclable plastic-based environment-friendly water gel is formed, and the plastic particles are dispersed in the internal structure of recycled aggregate.
