Embodiment 1

[0009] Add a single polyether polyol and toluene diisocyanate into a dry container at a mass ratio of 1:2.1, heat to 80°C, and keep it warm for 3 hours. Add formyl chloride and fly ash to the mixture, keep stirring at 80°C for 2 hours, cool down to 50°C and discharge to obtain component 1. Add the mixed polyether polyol and toluene diisocyanate with a mass ratio of 1:1.52 into a dry container, heat it to 80°C, keep it warm for 3 hours, and add the fly ash with a mass ratio of 1:2.77 to the mixed polyether polyol into the mixture, kept at 80°C and stirred for 2 hours, cooled to 50°C and discharged to obtain component 2. The above component 1 and component 2 are mixed in a mass ratio of 1:1 to obtain a polyurethane thermal insulation coating. The thermal conductivity of the coating is 0.031W / m 2 K.

Abstract

The process of producing heat insulating polyurethane paint relates to heat insulating building paint production. The production process of heat insulating polyurethane paint includes the following steps: 1. adding polyether polyol and toluene diisocyanate into one dry container, heating at 80 deg,c for 3 hr, adding benzoyl chloride and flyash, maintaining at 80 deg.c and stirring for 2 hr, and lowering to 50 deg.c to obtain component I; 2. adding polyether polyol and toluene diisocyanate into one dry container, heating at 80 deg,c for 3 hr, adding flyash, maintaining at 80 deg.c and stirring for 2 hr, and lowering to 50 deg.c to obtain component II; and 3. mixing the component I and the component II in the weight ratio of 1:1-3 to obtain the heat insulating polyurethane paint. The present invention has simple construction process and good heat insulating effect, and may be used in outer building wall.

Description

technical field [0001] The invention relates to a method for preparing a building thermal insulation coating, in particular to a method for preparing a polyurethane thermal insulation coating. Background technique [0002] At present, there are two main types of building exterior wall insulation materials: the first type is inorganic insulation materials such as expanded perlite and insulation mortar, and the second type is organic foam insulation boards represented by EPS. Among them, the first type of inorganic thermal insulation materials has low cost and simple construction, but the thermal insulation effect is not good; the second type of organic foam insulation boards has good thermal insulation effects, but the cost is high, and the construction process is complicated. Once the builder's sense of responsibility is not strong , It is easy to cause unqualified construction quality. It has become an urgent need to develop a thermal insulation material with moderate pric...
