Problems solved by technology

[0005] Conventional heat-reflective coatings are combined with anti-corrosion primers to form a protective system. Currently, solvent-based heat-reflective coatings are commonly used in the petrochemical industry. Multiple coats are required to achieve a thickness of 250-500 μm. 5-7 times of painting, the interval between each painting is between 8-24 hours, so applying two different types of paint can have a good protective effect, but because there are many construction procedures, it is a waste of materials It is not time-saving, and at the same time, the volatilized solvent has an impact on the environment

Abstract

The invention aims to provide a heat reflection type epoxy anti-corrosion coating. The heat reflection type epoxy anti-corrosion coating comprises the following components in percentage by weight: 25 to 35 percent of bisphenol A epoxy resin (E51), 10 to 15 percent of reactive diluent, 5 to 10 percent of titanium dioxide, 5 to 10 percent of hollow glass microsphere, 3 to 5 percent of infrared radiation powder, 10 to 24 percent of barium sulfate filler, 0.3 to 1.0 percent of rheological aid, 0.2 to 0.5 percent of dispersing agent and 15 to 25 percent of curing agent. Compared with the prior art, the anti-corrosion coating has the advantages that a solvent-free heavy-duty anti-corrosion coating system is adopted, so that environment can be improved, resources can be saved, cost can be reduced, economic benefit can be improved, the protection time can be prolonged to reach 15 years, and the coating is withy applying; and the coating can prevent corrosion, also has the functions of heat insulation and reflection, and is suitable for protecting the surface of steel, particularly the surfaces of open-air metal storage tanks and bunkers, so that the aim is fulfilled.

Description

technical field [0001] The invention relates to an anticorrosion coating, in particular to a heat-reflecting epoxy anticorrosion coating. Background technique [0002] Global economic losses due to corrosion of steel and other metals amount to one trillion U.S. dollars every year, accounting for 2-4% of the gross national product of various countries, which is six times the sum of losses caused by earthquakes, fires and typhoons. Our country’s annual loss is 1.19 trillion. RMB. [0003] The best way to deal with corrosion is to use anti-corrosion coatings, especially heavy anti-corrosion coatings that can stand the test of time in harsh corrosive environments. [0004] One of the most active areas of application of heavy-duty coatings today is the petrochemical industry, especially the large storage tanks and storage tanks that store petrochemicals in the open air, which are always exposed to the sun and rain. And these chemicals are deteriorated and damaged due to heat, s...
