Inorganic fiber heat-insulation layer protection surface layer and spraying method thereof

Abstract

The invention discloses an inorganic fiber-made heat-insulation layer protection surface layer. The protection surface layer is formed by mixing an inorganic cementing material, a dispersible emulsion powder, other fillers and auxiliary agents and the like. Water is added on the spot according to the weight ratio of powder to water being 1.0:0.7-0.8, and the materials are fully stirred and mixed to obtain slurry with a certain viscosity; the slurry is directly sprayed onto the surface of an inorganic fiber spray heat-insulation layer by a special spray machine; and a film is formed after hardening for a certain period of time so as to become the protection surface layer with waterproof, anti-crack and decorative effects.

Description

technical field [0001] The invention relates to a protective surface layer of a thermal insulation layer used for building energy conservation, in particular to a protective surface layer of an inorganic fiber thermal insulation layer and a spraying method thereof. Background technique [0002] In the construction of the existing inorganic fiber sprayed insulation layer, the treatment of the completed insulation layer is simply to use a special pressing plate or roller to flatten and compact the surface. After the construction is completed, the large-area fiber surface If it is exposed outside, few projects will carry out special treatment such as protection and decoration on the surface of the inorganic fiber spray insulation layer. As a result, in relatively humid basements, water vapor tends to gather on the surface of the insulation layer under the roof. When high water vapor is maintained for a long time, when the inorganic fiber spray insulation layer is exposed to suc...

AI Technical Summary

Problems solved by technology

As a result, in relatively humid basements, water vapor tends to gather on the surface of the insulation layer under the roof. When high water vapor is maintained for a long time, when the inorganic fiber spray insulation layer is exposed to such an environment for a long time, the insulation layer The water resistance will gradually lose. After being soaked by water, its own thermal insulation effect will be greatly reduced, and the bonding strength to the base layer will also be reduced accordingly, which will cause the insulation layer to fall off and hollow, and there is a certain safety hazard. , loses its own insulation effect

[0003] In addition, when the inorganic fiber sprayed insulation layer on the roof of the basement and other parts appears naked around people, it gives people a rough and uneven feeling, and the fiber cotton feels itchy when it falls on the body; Yellow, compared with the white wall, the color is inconsistent and the overall lack of aesthetic feeling
