Problems solved by technology

[0005] 2. The existing heat insulation materials are mainly due to poor construction performance, and the construction process must be formed by two or more times of plastering
Although thermal insulation materials are selected from different materials, they all have some common problems: large volume, poor thermal insulation performance, high water absorption, and poor comprehensive benefits when used in non-load-bearing walls of buildings; and the production process is complicated and the cost is high.
There are also problems of polystyrene thermal insulation composite wall surface damage, low flatness, hollow wall and cracking

Description

1. Technical field: [0001] The invention belongs to building materials, and in particular relates to a thermal insulation mortar. 2. Background technology: [0002] With the development of high-rise buildings and large-bay buildings, the requirements for lightness and thermal insulation performance of wall materials are getting higher and higher, so there have been wall insulation materials filled with minerals such as perlite and gypsum; existing insulation materials There are a large number of harmful substances in the formula, such as asbestos and other minerals, and the overall performance of the material such as heat insulation, anti-shrinkage, and impermeability is poor, and the water absorption is large; the traditional process has high transportation costs, short storage period, and inaccurate on-site ingredient measurement , Inconvenient construction and other technical and economic problems. [0003] There have been a lot of research and reports on thermal insulat...
