Multifunctional heat insulating plaster

Abstract

The invention relates to a multifunctional heat insulating plaster comprising a composite dried powder A and a polystyrene foam granule B, wherein the composite dried powder A comprises cement 50-80%, aluminosilicate glass hollow sphere material 10-40%, air-entrainer 0.005-0.05%, modifier 1-5%, water reducing agent 0.2-1.2%, fabric 0.1-5%, viscosifying agent 0.5-2%, the polystyrene foam granule B is prepared from finished expanded materials or reclaimed discarded polyphenylacetylene boards through slacking.

Description

1. Technical field: [0001] The invention belongs to building materials, and in particular relates to a novel multifunctional heat-insulating and heat-preserving 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-drying shrinkage, and impermeability is poor, and the water absorption is large; the traditional process has high transportation costs, short storage periods, and inaccurate on-site ingredient measurement , Inconvenient construction and other technical and economic problems. [0003] There have been a...

AI Technical Summary

Problems solved by technology

[0005] 2. Due to the poor construction performance of the existing heat insulation materials, it must be plastered twice or more during the construction process

[0006] Existing heat insulation materials focus on the overall structure, such as strength, density, etc., and lack the consideration of material functions, such as material construction, heat insulation, drying shrinkage, etc.

And although the existing thermal insulation materials are selected from different materials, they all have some common problems: large volume, poor thermal insulation performance, high water absorption rate, poor comprehensive benefit when used for non-load-bearing walls of buildings; and complex production process , the cost is high, and there are also problems such as polystyrene thermal insulation composite wall surface damage, low flatness, wall hollowing, and cracking.
