Abstract

The invention belongs to the field of coatings and particularly relates to a heat insulation and preservation coating. The water-borne energy-saving heat insulation and preservation coating for a petrochemical engineering oil tank is prepared by, by weight, hollow ceramic or hollow glass beads 35-65 parts, modified polymer emulsion 40-80 parts, padding 15-35 parts, additive 3-9 parts and water 50-90 parts. The modified polymer emulsion is a compound of silica sol and a polymer emulsion. The water-borne energy-saving heat insulation and preservation coating adopts hollow glass beads or the hollow ceramic as aggregate, modified polymer resin serves as an adhesive, softened water serves as a medium, additives are added to produce the coating through physical and chemical mixed processing. The coating is white or grey white sticky cream in appearance and forms a smooth film after being dried. The coating has good adhesion strength when being used on clean and dry surfaces in most cases. The coating does not contain harmful organic volatile matter, is non-toxic and is water-borne. No harmless waste and gas is produced in production and usage.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to thermal insulation coatings. Background technique [0002] The earth is irradiated by the sun every moment, and the sun has about 1765×10 17 J energy reaches the earth, and the huge energy provides the necessary conditions for human survival and life. But the intense radiation of the sun brings inconvenience to people's life. At noon in hot summer, the solar radiation energy on the surface can be as high as about 1000w / m 2 . Crude oil and refined oil storage tanks and light liquid chemical product storage tanks in petrochemical enterprises will continue to accumulate energy due to solar radiation heat, causing the surface and interior of the storage tank to heat up rapidly. At noon in summer, it reaches a 5000m 3 The solar radiant energy on the roof of the vaulted tank can be as high as 400kW, which increases the evaporation loss of crude oil and oil products. Over time, the loss is ...
