Problems solved by technology

In the process of use, the roof is easily eroded by natural disasters such as acid rain, and corrosion damage occurs, and the hardness of the roof itself also has higher requirements, which can better resist various disasters. During use, direct sunlight When it is irradiated on the roof surface, ultraviolet rays are likely to cause discoloration. Therefore, it is very necessary to develop a car roof coating with corrosion resistance, high hardness and good anti-ultraviolet effect

Embodiment 1

[0018] First, Ni Cr-SiC / Al was prepared by in situ synthesis 2 o 3 Metal / multiphase ceramic composite material has good interfacial solubility, and has the advantages of both metal and ceramic materials, high hardness and good ductility. Take 40% Ni Cr-SiC / Al 2 o 3 Add the material to 35% resin and mix and stir. During the stirring process, slowly add 2% titanium dioxide pigment, 5% alkylphenol ethylene oxide condensate emulsifier, 0.5% hydrogen-containing silicone oil modified 4-allyloxy -2-Hydroxybenzophenone UV absorber, 2% zinc oxide light shielding agent, 0.5% β-carotene free radical scavenger and 0.6% nano-calcium carbonate enhancer, continue to stir vigorously until the materials are mixed evenly, and The uniformly mixed mixture was added to 12% 3-methylpyrrolidone solvent, and 2.4% epoxy polyurethane curing agent was added to mix and stir together to finally obtain the target product. The resin contains 30% silicone resin, 30% acrylic resin and 40% cellulose acetat...

Embodiment 2

[0020] First, Ni Cr-SiC / Al was prepared by in situ synthesis 2 o 3 Metal / multiphase ceramic composite material, take 38% Ni Cr-SiC / Al 2 o 3 Add the material to 37% resin and mix and stir. During the stirring process, slowly add 1% titanium dioxide pigment, 5% sorbitan stearate polyoxyethylene ether emulsifier, 0.5% hydrogen-containing silicone oil modified 4-ene Propoxy-2-hydroxybenzophenone UV absorber, 2% titanium dioxide light shielding agent, 0.5% gentisic acid free radical scavenger and 0.6% nano-calcium carbonate enhancer, continue to stir vigorously until the materials are mixed evenly, Add the homogeneously mixed mixture into 14% 2,2-dimethylformamide solvent, and add 1.4% epoxy polyurethane curing agent to mix and stir together to finally obtain the target product. The resin contains 35% silicone resin, 35% acrylic resin and 30% acetate fiber.

Abstract

The invention discloses a car-roof coating material, which comprises: by mass, 20-40% parts of a resin, 1-5% parts of pigments, 1-5% parts of a curing agent, 10-20% parts of a solvent, and 1.4-1.8% parts of additives. The car-roof coating material also comprises 20-40% parts by mass of a metal / multiphase ceramic composite, which is Ni.Cr-SiC / Al2O3. According to the invention, corrosion resistance, hardness and strength of the coating itself can be effectively improved by adding the metal / multiphase ceramic composite into the coating, various disasters can be better prevented, ultraviolet radiation can be better resisted by adding a light screener and a radical scavenger, and service life of a car roof can be further effectively prolonged.

Description

technical field [0001] The invention relates to a coating, in particular to a coating material for the roof of an automobile. Background technique [0002] As an indispensable means of transportation in daily life, automobiles are more and more valued by people. As an important part of the car body, the quality of the car top directly affects the service life of the car itself. In the process of use, the roof is easily eroded by natural disasters such as acid rain, and corrosion damage occurs, and the hardness of the roof itself also has higher requirements, which can better resist various disasters. During use, direct sunlight When it is irradiated on the roof surface, ultraviolet rays are likely to cause discoloration. Therefore, it is very necessary to develop a car roof coating with corrosion resistance, high hardness and good ultraviolet resistance effect. [0003] In view of the above-mentioned existing defects in the roof of automobiles, the inventor activel...
