An ecological sponge brick made from waste rubber and plastic

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 ...

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
