Abstract

The invention relates to a coating system dedicated for outer wall reflecting and heat-insulating paint and a construction method of the coating system. The coating system is successively provided with heat-insulating leveling putties, an anti-cracking layer, sealing primer and a reflecting and heat-insulating paint finish paint layer from the surface of a base layer wall body, wherein the anti-cracking layer comprises two layers of heat-insulating leveling putties and glass fiber gridding cloth clamped between the two layers of heat-insulating leveling putties. The coating system dedicated for the outer wall reflecting and heat-insulating paint has the functions that the heat-insulating effect is enhanced, the anti-cracking effect is obvious, and the like by regulating the assorting of the base layers and applying the principle design, such as material deformation modulus access, and flexible gradual change.

Description

Technical field [0001] The invention relates to a coating system, more specifically, to a coating system special for exterior wall reflective and thermal insulation paint. Background technique [0002] Reflective heat insulation coatings for exterior walls reflect and radiate solar infrared and ultraviolet rays in the range of 400nm-2500nm to achieve the effect of reducing the temperature of the wall. At present, the thermal calculation of the wall is mainly the thermal resistance and thermal inertia index, because the equivalent thermal resistance of the external wall reflective insulation coating is only 0.20m 2 .K / W, can not meet the thermal resistance value required for building thermal calculation when used alone. At present, there is no complete exterior wall reflective thermal insulation coating coating program on the market, and users are generally worried about insufficient thermal insulation effect and easy cracking and water seepage during the promotion process, which ...
