The hollow brick includes the following raw materials: cement, shale ore, fly ash, tailing sand, Kaolin; the cement foaming material includes the following raw materials: cement, calcium silicate, calcium sulfate, bentonite, magnesium borate, corn straw powder, AR glass fiber, carbon fiber, water reducer, foaming agent, foaming regulator agent, catalyst, crosslinking agent, foam stabilizer, glyoxal, water. The environmental protection brick of the present invention has the advantages of excellent thermal insulation, sound insulation effect, light weight and pressure resistance, etc.; the method for preparing the environmental protection brick does not require autoclave curing, small investment in equipment, simple process, easy operation, easy promotion, and production The product quality is stable.

Description

【Technical field】 [0001] The invention belongs to the technical field of building material preparation, and in particular relates to an environment-friendly brick. 【Background technique】 [0002] With the popularization of building energy saving and the continuous improvement of people's demand for the comfort of living environment, thermal insulation materials have been paid more and more attention by people. Existing thermal insulation composite bricks or blocks mainly include multiple forms such as inlaying thermal insulation materials, setting thermal insulation interlayers, thermal insulation holes, and trenches. As one of the thermal insulation materials for houses, non-fired foamed bricks at room temperature are more and more popular because of their thermal insulation, sound insulation, fire prevention, and strength superior to traditional thermal insulation materials. However, the foamed bricks in the existing market have disadvantages such as poor impact resistanc...
