Problems solved by technology

[0002] At present, coatings are developing rapidly, but there are generally disadvantages of poor weather resistance, especially for storage tank coatings; usually, in order to increase weather resistance when designing formulas, people often use a baking process to add ultraviolet absorbers to the coatings, because storage tanks are exposed outdoors for a long time , as time goes by, the ultraviolet absorber is exposed

Abstract

The invention relates to the field of coating and in particular relates to reflection and heat-insulation coating for a storage tank and a preparation method thereof. The reflection and heat-insulation coating is prepared from the following raw materials: 50 to 60 parts of organic silicon modified alkyd resin, 25 to 35 parts of titanium white powder, 8 to 10 parts of composite iron-titanium powder, 8 to 10 parts of thermal reflection powder, 8 to 10 parts of quartz sand, 2 to 3 parts of a preservative, 1 to 3 parts of a de-foaming agent, 0.5 to 1 part of a thickening agent, 0.5 to 1 part of adispersant and 0.3 to 0.5 part of a wetting agent. The reflection and heat-insulation coating provided by the invention has excellent performance of shielding ultraviolet rays, infrared rays and the like; the thermal reflection powder is added and has the properties of multi-reflection, small heat absorption, capability of effectively preventing the transmission of heat energy and the like, so that the coating has excellent reflection and heat-insulation effects; the coating can be used for remarkably reducing the surface and inner temperatures of oil gas and chemical raw material storage tanks in summer and has a very good cooling effect. Meanwhile, the coating has excellent acid resistance, alkali resistance and salt resistance and has a remarkable protection effect on the storage tanks.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a reflective heat-insulating coating that can be used for storage tanks and a preparation method thereof. Background technique [0002] At present, coatings are developing rapidly, but there are generally disadvantages of poor weather resistance, especially for storage tank coatings; usually, in order to increase weather resistance when designing formulas, people often use a baking process to add ultraviolet absorbers to the coatings, because storage tanks are exposed outdoors for a long time , as time goes by, the ultraviolet absorber is exposed to sunlight, gradually decomposes, the coating is also aging, and it is easy to fall off in the end, so there is a very high safety risk, especially in high temperature weather, the temperature inside the storage tank is as high as 50 -60 degrees, it is easy to explode; in order to prevent problems, general customers adopt the method of shortenin...
