Anti-freezing self-cleaning water permeable brick and preparation method thereof

Abstract

The invention discloses an anti-freezing self-cleaning water permeable brick and a preparation method thereof. The anti-freezing self-cleaning water permeable brick is characterized by being prepared from the following raw materials in parts by weight: 2 to 5 parts of polyvinyl chloride, 2 to 5 parts of titanium dioxide, 1 to 2 parts of barium oxide, 10 to 20 parts of ethyl alcohol, 4 to 8 parts of silver-ammonia solution, 25 to 35 parts of ethyl acetate, 8 to 14 parts of activated carbon, 1 to 2 parts of boron carbide, 3 to 5 parts of polyacrylic ester, 3 to 5 parts of waste fabrics, 20 to 30 parts of aeolian sand, 30 to 40 parts of polytetrafluoroethylene emulsion, 10 to 15 parts of epoxy resin GCC135 and 10 to 15 parts of curing agent GCC137; silver particles are uniformly loaded on the titanium dioxide surface; then, the titanium dioxide is loaded by the active carbon; a series of continuous thorough self-cleaning effects that the active carbon adsorbs substances such as sulfur dioxide, silver ions activate and promote titanium dioxide catalysis, and the titanium dioxide decomposes the substances can be achieved; the polyvinyl chloride is added in a matched way; the difficult problem of poor anti-freezing performance in severe cold areas is solved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a frost-resistant self-cleaning permeable brick and a preparation method thereof. Background technique [0002] With the rapid development of the economy and the acceleration of urbanization, the urban surface is covered by more and more impermeable materials such as cement pavement and asphalt pavement, which brings convenience to traffic, but also causes many negative effects. The impermeable pavement, on the one hand, greatly reduces the infiltration of urban rainwater, which leads to the replenishment of groundwater, the continuous decline of groundwater level, and even causes problems such as land subsidence and seawater intrusion; on the other hand, rainwater on the road enters rivers through the urban drainage system, increasing The pressure on the urban drainage system and the rainwater that cannot be drained will cause a large amount of water to accumulate on the road...

AI Technical Summary

Problems solved by technology

[0003] In Wang Pingping's "Preparation and Performance Research of Resin Sand-based Permeable Brick", a kind of resin sand-based permeable brick was prepared by using aeolian sand, epoxy resin and curing agent. However, considering the practical application, there are still insufficient functions. For example, the adsorption and decomposition of surface attachments and harmful gases, the lack of excellent compression and crack resistance, etc.
