Metal guardrail coating with high weather resistance and stain resistance, and preparation method thereof

Abstract

The invention relates to a metal guardrail coating with high weather resistance and stain resistance, and a preparation method thereof. The coating is prepared from, by weight, 20-30 parts of polyester resin, 20-30 parts of hydroxyl acrylic resin, 10-15 parts of a fluorine-containing hydrophobic material, 1-5 parts of a cross-linking agent, 1-3 parts of boric acid, 1-3 parts of seashell powder, 3-5 parts of stainless steel powder, 1-3 parts of ultramicro wax powder, 1-3 parts of a functional filler, 0.1-0.5 part of a nanometer stain-resistant agent, 0.1-0.5 part of a nanometer anti-aging aid and 0.1-0.5 part of a nanometer heat insulation aid. The coating disclosed by the invention has extremely low surface tension and strong hydrophobic and anti-fouling capabilities, the contact area between dirt such as dust and the like which is not easy to adhere to and the surface of a coating layer is greatly reduced, the damage of ultraviolet rays to a coating film can be shielded, the weather resistance of the coating product in use is improved, and the service life of the product is kept long.

Description

technical field [0001] The invention relates to the technical field of synthetic adhesives, in particular to a highly weather-resistant and stain-resistant metal guardrail coating and a preparation method thereof. Background technique [0002] Metal materials have played a very important role in human society since ancient times and cannot be completely replaced so far. At the same time, the corrosion and aging of metal materials have caused great economic losses to society. As a protective material for metals, metal coatings have been valued and developed. In the face of the deteriorating environment of the earth and the rapid depletion of resources, and the increasingly high decorative performance requirements of urban development, metallic coatings, as an industrial coating, urgently need to embark on the development direction of environmental protection, high efficiency and better decorative performance. [0003] Anti-corrosion coatings can prevent corrosion of metals ...
