Problems solved by technology

Moreover, people have done a lot of research on water-based antirust coatings, but the flame retardant effect of the coatings is not significant. Research on flame retardant antirust coatings has also attracted much attention, but the adhesion and alkali resistance of the coatings still need to be improved.
Traditional anti-rust agents generally use nitrite and dichromate and other carcinogenic and teratogenic ingredients for anti-rust treatment, which has a great negative impact on the health of workers and environmental pollution

Abstract

The invention discloses weather-proof, antibacterial, flame-retardant and anti-rusting paint for metals. The paint contains the following raw materials in parts by weight: 28-34 parts of compound resin, 5-7 parts of polyvinyl alcohol, 2-4 parts of liquefied paraffin, 0.5-1.3 parts of a compound defoaming agent, 1-3 parts of zinc borate, 1-2 parts of zinc sulfate, 3-5 parts of antimonous oxide, 3-5 parts of diethylene glycol monobutyl ether, 5-7 parts of a flame retardant, 3-5 parts of sodium dodecyl benzene sulfonate, 6-8 parts of modified filing soil, 2-4 parts of a rare earth compound, 14-16 parts of mixed grease, 2-3 parts of a corrosion inhibitor, 2-4 parts of polycarbonate, 3-4 parts of a curing agent and 1-3 parts of an antibacterial agent. The paint provided by the invention is suitable for occasions in a salt-spray environment and a hygrothermal environment or requiring long-term rusting prevention, has excellent contact anti-rusting property, very good gas-phase anti-rusting effect and relatively good anti-friction performance, antibacterial activity and flame retardance, has a relatively strong adhesion force to metal products and can be widely applied to metal processing industry.

Description

technical field [0001] The invention relates to the technical field of metal rust prevention, in particular to a weather-resistant, antibacterial, flame-retardant and antirust paint for metal and a preparation method thereof. Background technique [0002] With the development of the country's economy, the industry has made great strides, and most industrial products use metal materials. During the manufacturing process, it is inevitable to remove rust products and carry out rust prevention between processes; It may be corroded by oxygen or acid-base medium in the environment. To prevent rust, the rust that has already occurred must be derusted and then rust-proofed. In order to avoid rust and reduce losses, people have adopted various methods. One of the most common methods of protection is to use antirust agents to protect metal products. Antirust agent is composed of adding one or more antirust additives (also known as oil-soluble corrosion inhibitor) and auxiliary additi...
