Metal anticorrosive paint and preparation method thereof

Abstract

The invention discloses a metal anticorrosive paint and a preparation method thereof. The metal anticorrosive paint is prepared from the following components in parts by mass: 10 to 15 parts of butylmethacrylate; 4-5 parts of cyclohexanone, 3-4 parts of titanium dioxide, 1-2 parts of an epoxy resin curing agent; 3 to 6 parts of propylene glycol phenyl ether; 10 to 15 parts of pentaerythritol; 8 to 15 parts of a pigment and filler; 5-6 parts of polyether silicone oil, 1-2 parts of polytetrafluoroethylene wax, 1-2 parts of a titanate coupling agent, 4-6 parts of a leveling agent, 1-2 parts of zinc phosphate, 15-25 parts of butyl acetate, 6-12 parts of graphite, 8-10 parts of hydroxypropyl methyl cellulose, 2-3 parts of xylene, 35-50 parts of a thermosetting high-salt resin and 15-25 parts of novolac epoxy resin and chlorinated polyether resin. The thermosetting high-salt resin has the characteristics of curing crosslinking and infusibility of a coating after crosslinking, an infusible hard-texture coating can be formed after a curing agent with a crosslinking reaction is added and heated, and the coating prepared from the thermosetting high-salt resin cannot be softened like a conventional thermoplastic coating under the condition of high temperature, and is good in stability.

Description

technical field [0001] The invention belongs to the field of anticorrosion paint preparation, and in particular relates to a metal anticorrosion paint and a preparation method thereof. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, and adding corresponding Auxiliary, a viscous liquid prepared with organic solvents or water; the main function of the coating is decoration and protection. During the construction and film-forming process of the coating, some physical and chemical changes will occur. These changes and the properties of the coating itself , will significantly affect the flow and leveling of the paint. According to relevant data, in industrially developed countries, the direct economic loss caused by corrosion accounts for 1% to 4% of the total nati...

[0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, and adding corresponding Auxiliary, a viscous liquid prepared with organic solvents or water; the main function of the coating is decoration and protection. During the construction and film-forming process of the coating, some physical and chemical changes will occur. These changes and the properties of the coating itself , will significantly affect the flow and leveling of the paint. According to relevant data, in industrially developed countries, the direct economic loss caused by corrosion accounts for 1% to 4% of the total national economic output value, and the annual corroded and rusted steel is about 1% to 4%. It accounts for 20% of the output, and about 30% of the equipment is scrapped due to corrosion. The economic loss caused by metal corrosion is as high as tens of billions of yuan every year. At the same time, the corrosion of metals accounts for 4% of the gross national product. The chemical or electrochemical action of the medium is destroyed. At the same time, there are also technical protection methods for coating the metal body. However, the technical means in the entire coating industry are uneven, and it is due to the environment's humidity, weathering, rain erosion, Factors such as exposure to the sun will accelerate the cracking and fading of the surface coating, which will lead to secondary corrosion of the metal, and the corrosion of the metal has spread throughout all fields of the national economy, bringing huge losses to the national economy. Therefore, it is necessary to provide a metal anti-corrosion Coating and preparation method thereof improve above-mentioned present situation
