Description

technical field

[0001] The invention relates to the field of building materials, in particular to an energy-saving and environment-friendly building material and a preparation method thereof. Background technique

[0002] Building energy conservation is the cheapest and most direct measure to improve people's living and working conditions, alleviate my country's energy shortage, promote sustainable economic development, and protect the ecological environment. It is also an important part of deepening economic system reform. Utilization is one of the main ways of building energy saving.

[0003] Due to the unreasonable formula structure of the existing environmental protection building materials, there are many shortcomings such as high thermal conductivity, low strength, large volume shrinkage, poor thermal insulation performance, hollow cracking, etc., and has certain water absorption, and the thickness is not easy to control. Great impact. Contents of the invention [0...
