Chemical storage tank polyurethane paint with weather resistance and heat insulation and preservation performance

Abstract

The invention provides chemical storage tank polyurethane paint with weather resistance and heat insulation and preservation performance. The chemical storage tank polyurethane paint with the weatherresistance and the heat insulation and preservation performance is prepared from the following steps: (1) successively adding the following components in parts by weight into a mixing tank: 20 to 50 parts of weather-resisting polyester thermosetting resin which can react with NCO, 20 to 70 parts of carboxymethylcellulose, 40 to 60 parts of inorganic fillers, 20 to 60 parts of vacuum microbeads, 0.02 to 1.5 parts of weather-resisting aids, 11 to 18 parts of antipollution aids, 13 to 20 parts of nano additives, 0.2 to 1.5 parts of dispersing agents, 0.2 to 0.5 part of defoaming agents, 0.5 to 1.5 parts of rheological aids, 0.5 to 1.5 parts of anti-settling agents, 0.5 to 3.0 parts of foaming catalysts, and 0.5 to 1.5 parts of flatting agents, and dispersing and grinding to a size lower thanor equal to 50 micrometers; and (2) adjusting the viscosity of a substance obtained in the step (1) by using 10 to 25 parts of environment-friendly organic solvents, and adjusting the color by using color paste to obtain a preparation component. The chemical storage tank polyurethane paint with weather resistance and heat insulation and preservation performance has the beneficial effects that thepolyurethane finishing paint has good foaming performance and weather resistance, and five years or above of heat insulation and preservation effect can be achieved when the chemical storage tank polyurethane paint is smeared on the surface of a chemical storage tank.

Description

technical field [0001] The invention relates to a polyurethane coating for chemical storage tanks with weather resistance and thermal insulation performance. Background technique [0002] In summer, large-scale chemical storage tanks exposed to the outdoors will have the problem of excessive tank temperature, which is often solved by heat-insulating coatings. [0003] Existing foam-type heat-insulation coatings can have a certain heat-insulation effect, but they have the defect of poor weather resistance; existing non-foaming heat-insulation coatings have good weather resistance, but they cannot Foaming often results in insufficient paint film thickness. [0004] In the prior art, there is an urgent need for a polyurethane coating for chemical storage tanks with weather resistance and thermal insulation properties. Contents of the invention [0005] In order to solve the problems in the prior art, the present invention provides a polyurethane coating for chemical storage...
