Problems solved by technology

[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. One of them is widely used. Usually, the lower insulation brick is a new type of building material synthesized by polymer materials. It has certain good fire resistance, heat insulation, sound insulation, crack resistance and waterproof performance, so as to achieve the effect of energy saving and environmental protection. Although this type of insulation brick has many performance advantages compared with ordinary sintered bricks, there are three problems in today's insulation bricks: high raw material cost, low compressive strength, and high dry density, which seriously affect the service life and purchasing power of insulation bricks. and shipping costs
