Abstract

The invention relates to the field of coatings and specifically relates to a reflective insulation coating for an oil tank and a preparation method thereof. The reflective insulation coating is composed of a component A and a component B; the component A comprises the following raw materials: 50-60 parts of acrylic resin, 25-35 parts of titanium dioxide, 8-10 parts of heat reflection powder, 8-10parts of xylene, 5-8 parts of n-butyl acetate, 0.5-1 part of anti-settling agent, 1.5-3.0 parts of dispersing agent and 0.5-1.0 part of de-foaming agent; the component B comprises the following raw materials: 70-75 parts of biuret and 0.1-0.2 part of auxiliaries. The reflective insulation coating is capable of excellently shielding ultraviolet rays, infrared rays, and the like, is characterized bymulti-reflection and low heat absorption, is capable of effectively obstructing heat transfer and has an excellent reflecting heat-insulation effect.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a reflective heat-insulating coating for oil tanks and a preparation method thereof. Background technique [0002] The earth is irradiated by the sun all the time, and the sun has about 1765×1017J of energy per second to reach the earth. 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. The solar radiation energy irradiated on the roof of a 5000m3 vaulted tank at noon in summer can be as high as 400kW, which increases the evaporation ...
