Environmental-protection anti-corrosive heat-dissipation powder paint, and preparation method and application thereof

Abstract

The invention discloses an environmental-protection anti-corrosive heat-dissipation powder paint, and a preparation method and application thereof. The environmental-protection anti-corrosive heat-dissipation powder paint comprises the following raw materials in parts by weight: 40-90 parts of matrix resin, 2-40 parts of curing agent, 0.5-10 parts of carbon nanotube, 0.5-2 parts of additive, 0-4.5 parts of hexagonal boron nitride, 0-15 parts of aluminum nitride, 0-10 parts of magnesium nitride, 0-10 parts of silicon carbide and 5-30 parts of pigment and filler. The composition and proportioning of the raw materials of the powder paint disclosed by the invention are scientific and reasonable. The experimental result indicates that the powder paint has the advantages of favorable heat-dissipation effect, high efficacy enhancement rate (higher than 60%) and favorable cooling effect (more than 20 DEG C), and can effectively solve the problem of poor heat-dissipation effect in the high-power electronic product, thereby prolonging the service life of the electronic product. The powder paint disclosed by the invention is free of organic solvent, and is environment-friendly and safe; the powder paint disclosed by the invention also has favorable comprehensive properties, such as flexibility, hardness, adhesive force and the like, and stable chemical properties; and the coating formed by the powder paint has the advantages of high corrosion resistance and shock resistance, favorable insulation property and wide application range.

Description

technical field [0001] The invention relates to a powder coating, in particular to an environment-friendly anti-corrosion and heat-dissipating powder coating, a preparation method thereof and its application in preparing an anti-corrosion and heat-dissipating coating. Background technique [0002] With the rapid development of China's economy, various LED lights, electrical appliances and electronic equipment have been developed at a high speed, but LEDs, various electrical appliances and electronic equipment will generate a lot of heat during long-term work, and the heat dissipation area of ​​various electronic equipment itself Smaller, poor heat dissipation performance, a large amount of heat affects the service life and performance of the equipment, so it is often necessary to coat a layer of auxiliary heat dissipation coating on the surface of the equipment. The heat dissipation coating of the existing technology has developed rapidly in recent years, such as the Chinese ...

Problems solved by technology

[0002] With the rapid development of China's economy, various LED lights, electrical appliances and electronic equipment have been developed at a high speed, but LEDs, various electrical appliances and electronic equipment will generate a lot of heat during long-term work, and the heat dissipation area of ​​various electronic equipment itself Smaller, poor heat dissipation performance, a large amount of heat affects the service life and performance of the equipment, so it is often necessary to coat a layer of auxiliary heat dissipation coating on the surface of the equipment. The heat dissipation coating of the existing technology has developed rapidly in recent years, such as the Chinese patent : 200810146607.5 discloses a heat-dissipating coating and a preparation method thereof, 200910199955.3 discloses a self-radiating nano-ecological coating and a preparation method thereof, and 201010119910.3 discloses a heat-conducting insulating material and a manufacturing method thereof, but coatings in the prior art are mostly Liquid paint, containing a large amount of organic solvents in the liquid paint, in the process of manufacture and construction, there will be a large amount of organic solvent volatilization, all can cause great damage to people and the environment, and the liquid paint of the prior art is in transportation and storage Very inconvenient, poor safety performance, and the efficiency improvement rate of the existing solid heat dissipation coating is low, the cooling effect is not obvious, generally the cooling effect cannot exceed 20 degrees, it is difficult to meet the heat dissipation requirements of high-power components, and the existing Technology heat dissipation coating, the role is relatively simple
