Problems solved by technology

At present, the epoxy resin in the coating is full of ordinary bisphenol A epoxy resin, but because the molecular structure of ordinary bisphenol A epoxy resin contains benzene rings, its UV resistance is poor, and its weather resistance is also very bad. It is easy to degrade under the action of ultraviolet rays and water vapor in the external environment, so it cannot be applied to outdoor products

Abstract

The invention discloses an anti-ultraviolet outdoor epoxy resin coating, which comprises the following components: cycloaliphatic glycidyl ether epoxy resin, cycloaliphatic glycidyl ester epoxy resin, zinc oxide particles, talcum powder, and quartz sand , xylene, n-butanol, butyl acetate, dispersants, defoamers and leveling agents. Through the above method, the anti-ultraviolet outdoor epoxy resin coating of the present invention has stable performance, good weather resistance, will not decompose and deteriorate after long-term exposure to the sun, is suitable for use under various temperature and humidity conditions, and will not And aging, nano-scale zinc oxide particles can scatter and absorb ultraviolet light, and can be widely used outdoors.

Description

technical field [0001] The invention relates to an epoxy resin coating, in particular to an anti-ultraviolet outdoor epoxy resin coating. Background technique [0002] As we all know, epoxy resin has excellent moisture resistance, chemical resistance and corrosion resistance, and has the advantages of high modulus and good dimensional stability. The application of epoxy resin in coatings occupies a very large proportion, and is widely used as anti-rust primer, floor paint, industrial heavy-duty anti-corrosion paint, drinking water tank paint, oil tank paint, etc. At present, the epoxy resin in the coating is full of ordinary bisphenol A epoxy resin, but because the molecular structure of ordinary bisphenol A epoxy resin contains benzene rings, its UV resistance is poor, and its weather resistance is also very bad. It is easy to degrade under the action of ultraviolet rays and water vapor in the external environment, so it cannot be applied to outdoor products. Contents of...
