Problems solved by technology

[0003] Existing antirust paints are mainly made of epoxy resin or polyurethane resin as raw materials. However, epoxy resin and polyurethane resin have low elongation and high brittleness after curing, and are easy to crack when subjected to external force, thus making them in the air Moisture and oxygen easily enter the protected metal surface through the cracks of the anti-rust paint, causing the protected metal to corrode and rust, and there is still room for improvement

Abstract

The invention relates to the technical field of coating, and provides iron oxide red epoxy aluminum powder anti-rust paint against the problem that the anti-rust coating has relatively large brittleness and is easily cracked due to external force. The paint comprises a component A and a component B in a mass ratio of (4.5-5.5):1, wherein the component A is prepared from the following ingredients in parts by mass: 52.5-70 parts of epoxy resin, 21-28 parts of iron oxide red powder, 27-36 parts of silver powder, 15-20 parts of xylene, 4.5-6 parts of butanol, 3-4 parts of a silane coupling agent and 22.5-30 parts of polysiloxane; and the component B is prepared from a curing agent, flexibilizer and xylene in a mass ratio of 3:1:1. According to the method, by adding the flexibilizer, the toughness of epoxy resin can be increased, the bearing strength of epoxy resin is improved, and the strength of the iron oxide red epoxy aluminum powder anti-rust paint can be enhanced, so that the iron oxide red epoxy aluminum powder anti-rust paint cannot be cracked easily, and the situation that protected metal is corroded can be reduced.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an iron red epoxy aluminum powder antirust paint. Background technique [0002] Antirust paint is a coating that protects metal surfaces from chemical or electrochemical corrosion from the atmosphere, sea water, etc. In order to protect the metal, the metal surface is usually covered with a layer of anti-rust paint. [0003] Existing antirust paints are mainly made of epoxy resin or polyurethane resin as raw materials. However, epoxy resin and polyurethane resin have low elongation and high brittleness after curing, and are easy to crack when subjected to external force, thus making them in the air The moisture and oxygen in the environment can easily enter the protected metal surface through the cracks of the anti-rust paint, causing the protected metal to corrode and rust, and there is still room for improvement.
