Problems solved by technology

There are many types of bricks used in construction, which can be roughly divided into two categories, one is load-bearing bricks, and the other is non-load-bearing bricks. Therefore, under the condition of social demand, thermal insulation bricks must meet the requirements of light weight and high load-bearing strength. However, many insulation bricks in the prior art still do not meet the above requirements, and there are still quality problems, which seriously affect the reliability and safety of construction projects. The insulation brick has far-reaching significance to the development of society and construction industry

Description

technical field [0001] The invention relates to the technical field of new polymer building materials, in particular to a high-strength light-weight insulating brick and a preparation method thereof. Background technique [0002] With the rapid development of the national economy and the continuous improvement of people's living standards, the consumption of energy is also increasing, and the problem of energy shortage is becoming more and more prominent. Therefore, people pay more and more attention to energy-saving and environmentally friendly building materials. A kind of widely used. There are many types of bricks used in construction, which can be roughly divided into two categories, one is load-bearing bricks, and the other is non-load-bearing bricks. Therefore, under the condition of social demand, thermal insulation bricks must meet the requirements of light weight and high load-bearing strength. However, many insulation bricks in the prior art still do not meet the...
