Abstract

The invention relates to the field of coatings and specifically relates to a heat-insulating anticorrosion bi-component coating for an outer wall of an oil tank and a preparation method thereof. The heat-insulating anticorrosion bi-component coating comprises a component A and a component B; the component A comprises the following raw materials in parts by weight: 50-60 parts of acrylic resin, 15.0-20.0 parts of titanium dioxide, 3.0-5.0 parts of thermal reflection powder, 5.0-8.0 parts of quartz sand, 0.3-0.5 part of surface active agent, 1.5-3.0 parts of dispersing agent, 0.1-0.5 part of anti-settling agent, 0.5-1.0 part of de-foaming agent and the balance of water; the component B comprises the following raw materials in parts by weight: 70-75 parts of biuret and 0.1-2.0 parts of auxiliaries. The coating can achieve ultrahigh reflectivity, is capable of excellently reflecting solar radiation and achieving heat-insulating and cooling effects and has excellent coating hardness, abrasion resistance, alkali resistance and water resistance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a heat-insulating and anti-corrosion two-component coating for the outer wall of an oil tank 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 ...
