Embodiment 1

[0026] A thermal insulation system for thermal insulation mastic reflective heat insulation coatings for external walls, comprising a thermal insulation layer 1 and a coating system 5, the coating system 5 is composed of a primer layer 2, a putty layer 3 and a finishing layer 7 of reflective thermal insulation coatings. The thermal insulation plaster reflective thermal insulation paint exterior wall thermal insulation system is constructed on the base layer 6, and the thermal insulation layer 1 is connected to the base layer 6.

[0027] Among them, the insulation layer 1 is thermal insulation and waterproof cement, and its formula is: 18.0%~19.0% of styrene-acrylic emulsion, 15.5%~16% of silica sol, 0.9%~1.0% of ester alcohol, 0.2%~0.3% of thickener, anti-mildew Agent 0.1%~0.2%, ammonia water 0.1%~0.2%, dispersant 0.2%~0.3%, polystyrene particles 1.5%~2.2%, vitrified microbeads 12~19%, aluminum silicate 15%~26%, functional Fiber 0.7%~0.9%, coupling agent 0.1%~0.3%, wetting age...

Embodiment 2

[0082] All the other are identical with described embodiment 1, and difference is that described putty layer is waterproof putty, and is made of polymer rubber powder, portland cement, ground calcium carbonate, quartz powder, talcum powder, defoamer and hydroxyl Propyl methyl cellulose is made, and the addition amount of described polymer milk powder is 25%

Embodiment 3

[0084] The rest is the same as that of Example 2, except that the hydroxypropyl methylcellulose is 100,000 Pa·S, and the added amount of the polymer milk powder is not less than 35%.

Abstract

The invention discloses an insulation mortar reflective insulation coating external wall insulation system and construction process thereof. The system comprises an insulation layer and a coating layer system, wherein the coating system is composed of a primary coat, a putty layer and a reflective insulation coating decorating face layer. The construction process comprises a preparation stage and a construction stage. The Insulation mortar reflective insulation coating external wall insulation system is low in manufacturing cost and excellent in durability, has good weather fastness, and can meet the use standard on an outer wall in terms of water absorption, impact strength, resistance to freezing, thawing and wear resistance.

Description

technical field [0001] The invention belongs to the field of building materials, and more specifically, the invention relates to a thermal insulation system of thermal insulation mastic reflective thermal insulation paint for an external wall and a construction process thereof. Background technique [0002] When the current architectural reflective heat insulation coatings are applied in building energy-saving projects in hot summer and cold winter regions, an insulation layer needs to be configured to meet the needs of heat insulation. For example, use expanded polystyrene board, extruded polystyrene board or building insulation mortar as the insulation layer. Due to the poor crack resistance of the anti-crack protective layer or the poor dimensional stability of the thermal insulation layer, the external thermal insulation system of the external wall formed in this way often leads to cracking and water seepage of the external thermal insulation system of the external wall....
