Abstract

The invention discloses anti-corrosion paint for a guardrail surface layer and a preparation method thereof, and relates to the field of paint. The paint is prepared from the following raw materials in parts by weight: 30 to 40 parts of epoxy resin, 25 to 30 parts of organic silicon resin, 10 to 20 parts of polyvinyl acetate, 5 to 10 parts of mica powder, 6 to 12 parts of attapulgite, 4 to 10 parts of silicon dioxide, 3 to 8 parts of ceramic fiber, 3 to 6 parts of nanometer titanium dioxide, 3 to 6 parts of nanometer magnesium hydroxide, 3 to 6 parts of nanometer antimonous oxide, 2 to 5 partsof nanometer iron powder, 3 to 6 parts of tea meal powder, 4 to 7 parts of bamboo charcoal powder, 2 to 5 parts of zirconium oxide, 1.8 to 3.6 parts of pigments, 2.5 to 4.5 parts of silane coupling agents, 2.2 to 3.8 parts of anti-aging agents, 1.4 to 3.1 parts of leveling agents and 2.5 to 4.8 parts of tackifiers. The anti-corrosion paint has the advantages of high bonding performance, stable physicochemical property, high anti-corrosion performance, difficult pulverization falling, high anti-mechanical-impact performance, bacteriostatic effect and air purification effect.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an anti-corrosion coating for the surface layer of a handrail and a preparation method thereof. Background technique [0002] Handrails are mainly used for the protection and protection of personal safety and equipment and facilities in residences, highways, commercial areas, public places and other occasions, which can be seen everywhere in our lives. Handrails are often made of steel, such as: stainless steel, round steel pipe, square steel pipe or profiled steel plate, iron wire, etc. In order to improve the service life of the handrail and reduce the corrosion of the handrail, in recent years, the plugging of aluminum alloy material has been popular, or a layer of paint film has been sprayed on the surface of the handrail. The use of aluminum alloy material for plugging is relatively expensive, which increases the overall cost of the handrail. Although the spray paint film is cheap,...
