Description

technical field

[0001] The invention relates to the field of building materials, in particular to an environment-friendly thermal insulation 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, the existing paving materials have many shortcomings such as high thermal conductivity, low strength, large volume shrinkage, poor thermal insulation performance, hollow cracking, etc., and have certain water absorption, and the thickness is not easy to control, which is affected by construction. big.
