Thermal insulation paint used on buildings, and preparation method thereof

Abstract

The invention discloses a thermal insulation paint used on buildings, and a preparation method thereof. The thermal insulation paint used on buildings is prepared through following steps: a special equipment (a stone mill method paint film coating dispenser) is used for preparing an A paint and a B paint; the A paint and the B paint are mixed at a mass ratio of 80-120:10 so as to obtain a finishedproduct. The thermal insulation paint is excellent in thermal insulation effect, excellent in heat radiation performance, chemical drug resistance, and anti-permeability; thin coating construction area is large; coating layers are flat and smooth; coating film service life is longer than 20 years; any colors can be obtained through blending; thermal insulation effect and decoration effect can beachieved at the same time; national energy saving requirements are satisfied; and economical, environmental, and social benefit is obvious.

Description

technical field [0001] The invention relates to the field of thermal insulation coatings, in particular to a thermal insulation coating for stone-milled buildings, a preparation method thereof, and a special device for preparing the coating. Background technique [0002] The external thermal insulation system of external wall thermal insulation and decorative panels (referred to as thermal insulation and decorative integrated panel system) is composed of adhesives, thermal insulation decorative panels, sealing materials and auxiliary anchors. During construction, first make a waterproof line leveling layer on the base wall, and fix the thermal insulation decorative board on the base by mainly sticking and combining with anchors. The thermal insulation decorative board is composed of thermal insulation layer, inorganic resin board, facing layer and connectors. The insulation layer material can choose EPS board, XPS board, PUR board, phenolic board, rock wool board. The effe...

Problems solved by technology

[0003] Defects in existing technical solutions: ①Whether it is the traditional XPS polystyrene board insulation or the new insulation and decoration integrated board, the construction is very troublesome, and both need to be assembled and anchored with steel nails. The construction process is complicated and the construction quality is very poor. It is difficult to control, and the quality of construction depends more on the on-site performance of the construction personnel; ②The existing thermal insulation system has very large safety hazards, and incidents of the overall external thermal insulation system of high-rise buildings falling off and hurting people often occur; ③The fire protection rating of the existing thermal insulation system Poor, there have been many fire accidents across the country. Basically, the fire protection level of existing thermal insulation materials is B2 or B3, which is flammable or slow burning. It is difficult to reach the A level with existing technologies; Technical problems, especially in summer, when the indoor temperature is high, the thermal insulation layer is very unfavorable for indoor and outdoor heat exchange, which is equivalent to a person wearing the same thick padded jacket in winter and summer, when the body generates huge heat, still wearing a thick padded jacket , there is no way to dissipate the heat
