Special environment-friendly building material for walls and preparation method thereof

Abstract

The invention discloses a special environment-friendly building material for walls. The building material is prepared from the following raw materials in parts by weight: 10-20 parts of Portland cement, 10-20 parts of red clay, 3-5 parts of talcum powder, 5-8 parts of coconut shell scrap, 1-8 parts of carbon black, 1-3 parts of magnesium oxide, 5-8 parts of mica powder, 1-5 parts of glass fiber, 30-50 parts of water and 20-50 parts of sponge. The building material disclosed by the invention has the advantages of reasonable and accessible raw material formula, simple and reliable preparation method, favorable heat-insulating property, favorable ductility and low flammability, is capable of prolonging the service life of the wall and preventing the wall from crack, has the functions of cold shielding and heat insulation, and thus, has high social benefits and economic benefits.

Description

technical field

[0001] The invention relates to the field of building materials, in particular to a special environment-friendly building material for walls 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. big influence.
