Inorganic composite insulation board external wall insulation system

Abstract

The invention provides an inorganic composite thermal insulation board external wall thermal insulation system. The bottom layer adopts a water-based paint composed of 50-70% pure acrylic emulsion, 5-10% functional additives, and 25-45% quartz powder as a filler. The middle layer adopts thermal insulation board and reinforced fiber composite foamed cement board, and the mesh cloth for reinforcing fiber adopts alkali-resistant mesh cloth, the bonding mortar adopts rubber powder polymer mortar binder, and the surface adopts polymer cement plastering mortar, which solves the problem of The problem of water seepage that often occurs in the thermal insulation system and the problem of short thermal insulation life are eliminated. The thermal insulation system has the same life span as the wall, and the energy saving effect of this system is greatly improved.

Description

technical field [0001] The invention relates to a waterproof system, in particular to an inorganic composite thermal insulation board external wall thermal insulation system. Background technique [0002] External wall insulation refers to the use of certain fixing methods (bonding, mechanical anchoring, sticking + mechanical anchoring, spraying, pouring, etc.), and the thermal insulation material with low thermal conductivity (better thermal insulation effect) is fixed with the building wall. , an engineering practice that increases the average thermal resistance of the wall to achieve thermal insulation or thermal insulation. [0003] At present, the fire protection level required for external wall insulation is gradually increasing. First, the insulation effect and A-level fire protection performance must be achieved. The number of rock wool is A-level fire protection, but its water absorption is high, and it is easy to absorb water, which will cause the insulation effect...

AI Technical Summary

Problems solved by technology

[0005] The invention aims to solve the problems of short service life of the traditional thermal insulation system of external wall thermal insulation, easy occurrence of water seepage in the wall, and poor energy-saving effect

[0007] The beneficial effects of the present invention are: solve the problem of water seepage that often occurs in the thermal insulation system, and the problem of short thermal insulation life. In the severe summer, the energy-saving effect is very significant, and the outer coating has good weather resistance, UV resistance, and durability. Compared with traditional exterior decorative coatings: although the decorative performance becomes worse, the practical function is enhanced
