Abstract

The invention relates to a thermal insulation material with a low heat conductivity coefficient. The thermal insulation material is prepared from the following components in parts by weight: 40-60 parts of diatomite, 30-42 parts of fibers, 40-60 parts of cement and 6-10 parts of an additive, wherein the fibers are one of mineral fibers and centrifugal glass fibers, and the additive contains a flame retardant and a foaming agent. Compared with a traditional external wall building material, the thermal insulation material has the advantages of being very good in thermal insulation property, strong in coagulability, unlikely to fall off, accordant with national policies on traditional external thermal insulation material and worthy popularizing.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a thermal insulation material with low thermal conductivity. Background technique [0002] The concept of building energy conservation has been developed to this day. It refers to the adoption of active and effective measures to rationally reduce energy consumption in buildings without affecting people's comfort (that is, the living room temperature is not lower than 18 degrees Celsius in winter and not higher than 26 degrees Celsius in summer). Use energy and use energy efficiently, thereby improving the energy efficiency of buildings. Actively taking various measures to promote the development of building energy conservation has profound significance in many aspects to the world and our country. [0003] In terms of research and development of external thermal insulation materials for external walls, the materials traditionally used for external walls in my country are cement...
