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

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.

The invention relates to a wear-resisting super-hydrophobic coating composition as well as a preparation method and application thereof. The composition is prepared from a nano-material dispersion solution and a binding material dispersion solution. The nano-material dispersion solution is prepared by mixing a nanoparticle material, a hydrophobic silane coupling agent and a volatile solvent, wherein nanoparticles form a rough structure with a micro-nano dual scale through a mutual effect of the nanoparticles and the structure is dispersed in the solution of the hydrophobic silane coupling agent; the hydrophobic silane coupling agent has one or more groups and covalent bond connection is formed by the hydrophobic silane coupling agent and the micro-nano dual rough structure; meanwhile, thewear-resisting super-hydrophobic coating composition at least contains one hydrophobic group. A super-hydrophobic coating layer formed by the super-hydrophobic coating composition keeps a long-term effective super-hydrophobic property; the coating composition adopts a binding material so that the binding force between a super-hydrophobic structure and a matrix is enhanced and the protection effectof the coating layer is enhanced; a processing technology of the super-hydrophobic coating layer is simple and convenient and large-area construction is facilitated.
