Problems solved by technology

However, in the prior art, the technology of making hydrophobic floor tiles from carpets or automobile interior scraps is still immature, and there are few related technical records, and the water-permeable bricks made of rubber in other technologies have problems in the process of water storage and water permeability. Excessive surface energy leads to the problem that rainwater is not easy to disperse and permeate quickly when it flows through the brick surface. At the same time, there is a problem of low cohesion or cohesion of the brick body, which leads to the problem that the brick body can be broken or even crushed once it is compressed, which seriously affects Use effect and service life

Embodiment 1

[0034] A kind of carpet or automobile upholstery scrap recycling process, comprises the following steps:

[0035] 1) Broken carpets or car interior scraps; remove other adherents and large impurities from the scraps, and then soak them in a surfactant solution for 4-5 hours to soften them. The concentration of the soaking solution is 5-8% After that, remove the leftover material and clean it with clear water; then add it to a cylinder-type pulverizer, add water and grind it, the quality of the water added is 20-22% of the quality of the leftover material, and the leftover material is broken; then the broken leftover material is mechanically dehydration and drying;

[0036] 2) Heating the scraps of carpet or automobile interior decoration to partially melt to form a plastic body and make solid particles; send the dried and broken scraps into the extruder from the feed port, knead and melt; then knead the molten material High-shear mixing; then pass through two layers of 65-75 ...

[0047] A kind of carpet or automobile upholstery scrap recycling process, comprises the following steps:

[0048] 1) Broken carpets or car interior scraps; remove other adherents and large impurities from the scraps, and then soak them in a surfactant solution for 4-5 hours to soften them. The concentration of the soaking solution is 5-8% After that, remove the leftover material and clean it with clear water; then add it to a cylinder-type pulverizer, add water and grind it, the quality of the water added is 20-22% of the quality of the leftover material, and the leftover material is broken; then the broken leftover material is mechanically dehydration and drying;

[0049] 2) Heating the scraps of carpet or automobile interior decoration to partially melt to form a plastic body and make solid particles; send the dried and broken scraps into the extruder from the feed port, knead and melt; then knead the molten material High-shear mixing; then pass through two layers of 65-75 ...

Embodiment 3

[0064] A kind of carpet or automobile upholstery scrap recycling process, comprises the following steps:

[0065] 1) Broken carpets or car interior scraps; remove other adherents and large impurities from the scraps, and then soak them in a surfactant solution for 4-5 hours to soften them.

Abstract

A process for recycling carpet or automobile interior scraps and the prepared hydrophobic floor tiles, comprising the following steps: 1) crushing the scraps; 2) heating the scraps until they are partially melted to form a plastic body and make solid particles; 3) taking step 2 ) to the small granules prepared in ), add preparation materials to it, and mix evenly; 4) Pour the mixed product in step 3) into a mold, harden under pressure, and demould to obtain a finished product. The process investment of the invention is small, the benefit is high, and the application range is wide. The hydrophobic floor tiles prepared by the invention have good water permeability, elasticity, non-slip, environmental protection, odorless and are suitable for outdoor walkways.

Description

technical field [0001] The invention relates to the technical field of recycling and preparation of carpet or automobile interior scraps, in particular to a process for recycling carpet or automobile interior scraps and prepared hydrophobic floor tiles. Background technique [0002] The corners in the production of carpets or car interiors and the trimmings to obtain the design shape account for 3-10% of the overall finished product. The disposal of leftovers is directly related to the total production cost and environmental protection issues. The previous treatment was direct landfill or incineration. Most of the materials used in carpets or car interiors are polymer materials, and it takes decades or even a hundred years to degrade naturally. Incineration involves problems in the incineration process. Low-temperature combustion has more flue gas and dust, which will cause greater damage to the environment. Although high-temperature incineration is relatively thorough in ...
