Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem that the prior art utilizes recycled plastics and recycled rubber to prepare bricks. During the process of water storage and water seepage, the surface energy is too high, which makes it difficult for rainwater to disperse and permeate quickly when it flows through the brick surface. At the same time, there is the 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 pressed, and there is a problem that it is easy to seep and not easy to clean. It provides a kind of use of waste rubber and plastic. ecological sponge brick

[0053] Step 8: The eco-sponge brick forming mold has a vibration mechanism. Apply a heat-resistant mold release agent on the bottom metal plate of the mold and the inner wall of the mold frame. Put the fabric prepared in step (6) into the mold and vibrate evenly to form an ecological Sponge brick surf...

Embodiment 1

[0060]In this embodiment, waste and old natural rubber, waste and old neoprene rubber, waste and old nitrile rubber, and waste and old polyethylene, waste and old polypropylene, waste and old polyester, waste and old polystyrene, etc. are first sorted out. The waste rubber is cleaned, dehydrated and dried, and then pulverized by a pulverizer, or washed, dehydrated and dried after pulverization to form waste plastics and waste rubber pulverized materials, and the pulverized materials are sieved and selected as The particle size is about 1-3mm of fine-grained waste plastic particles and 3-5mm of coarse-grained waste rubber particles. At the same time, the waste glass is cleaned, dehydrated and dried, and then crushed into waste glass particles with a particle diameter of about 0.5-2mm by a pulverizer for standby.

[0061] In the present embodiment, the surface layer is compounded according to the following components and parts by weight: 20 parts of fine-grained waste rubber par...

Embodiment 2

[0074] In this embodiment, waste and old ethylene propylene rubber, waste and old silicone rubber, waste and old fluororubber, and waste and old polyethylene, waste and old polypropylene, waste and old polyester, waste and old polyvinyl chloride, etc. are first sorted out. The method and steps of 1 wash, dehydrate and dry waste rubber, waste plastic and waste glass, and select waste plastic particles with fine particle size, waste rubber particles with coarse particle size and waste glass particles through sieving.

[0075] In this embodiment, the surface layer is compounded according to the following components and parts by weight: 40 parts of fine-grained waste rubber particles, 40 parts of fine-grained waste plastic particles, 15 parts of nano-titanium dioxide, 10 parts of rare earth, 30 parts of calcium carbonate , 30 parts of bentonite, 12 parts of activated alumina, 25 parts of polytetrafluoroethylene sintered powder, 10 parts of block copolymer, 1.5 parts of calcium lign...

Abstract

The present invention relates to an ecological sponge brick prepared from waste rubbers and waste plastics. The ecological sponge brick comprises a surface layer and a bottom layer, wherein the surface layer is prepared from fine particle size waste rubber particles, fine particle size waste plastic particles, nanometer titanium dioxide, rare earth, calcium carbonate powder, bentonite, active alumina, polytetrafluoroethylene sintered powder, a block copolymer, calcium lignosulfonate, isomeric 13 alcohol polyether, polyoxyethylene sorbitan tristearate and a composite auxiliary agent, and the bottom layer is prepared from coarse particle size waste rubber particles, coarse particle size waste plastic particles, waste glass, bentonite, gravel, calcium silicate, a block copolymer, polyacrylamide, isomeric 13 alcohol polyether, polyoxyethylene sorbitan tristearate and a composite auxiliary agent. According to the present invention, the ecological sponge brick has characteristics of strong water permeation, high porosity, more through holes, good water retention, good skid resistance and good scale resistance, and achieves the high value comprehensive utilization of waste rubbers and waste plastics.

Description

technical field [0001] The invention relates to the technical field of preparation of municipal road permeable bricks, in particular to ecological sponge bricks made of waste rubber and plastic. Background technique [0002] At present, the ground of city squares, commercial streets, sidewalks and community activity venues is mainly paved with materials with poor water permeability such as granite and marble ceramic tiles, which increases the burden on urban drainage facilities, resulting in When heavy rain hits, the city is very prone to waterlogging. The fundamental reasons are: on the one hand, the urban underground drainage system lags behind the urban construction; burden. However, when the runoff on the ground is effectively controlled, the rainwater brought by heavy rains has correspondingly lower requirements on the underground pipe network. It can be seen that in order to fundamentally solve the problem of waterlogging in old urban areas where urban reconstruction ...
