Embodiment 1

[0038] The preparation method of a white multifunctional modified acrylic polyurethane rubber coating is as follows: the preparation of component A: add the modified acrylic resin, anti-sedimentation agent, dispersant, and solvent into the container, and disperse for 20 minutes at a speed of 1000 rpm with a high-speed disperser , add pigments and fillers to disperse at high speed for 45 minutes, grind, control the fineness to no more than 20 μm, then add light stabilizer, wear-resistant additive, leveling agent to the ground paint, disperse at high speed for 60 minutes, mix evenly, and finally add some solvent to adjust When the viscosity reaches 70s, the A component that meets the requirements is obtained; the preparation of B component: mix the polyether-modified polycyanate prepolymer and the aliphatic isocyanate multimer evenly, and then the B component that meets the requirements is obtained. Components: When using, mix A and B components according to the molar ratio of OH...

Embodiment 2

[0040] A blue multifunctional modified acrylic polyurethane rubber paint production method is as follows: the preparation of component A: add modified acrylic resin, anti-sedimentation agent, dispersant, and solvent to the vessel, and disperse it with a high-speed disperser at a speed of 1200rpm 15 minutes, add pigments and fillers to disperse at high speed for 40 minutes, grind, control the fineness to no more than 20 μm, then add light stabilizer, wear-resistant additive, leveling agent to the ground paint, disperse at high speed for 60 minutes, mix evenly, and finally add some solvent Adjust the viscosity to 75s to obtain the A component that meets the requirements; the preparation of the B component: mix the polyether-modified polycyanate prepolymer and the aliphatic isocyanate multimer evenly to obtain the A component that meets the requirements Component B; when used, mix components A and B according to the molar ratio of 0.95 between the OH contained in the modified acry...

Embodiment 3

[0042]The preparation method of a white multifunctional modified acrylic polyurethane rubber coating is as follows: the preparation of component A: add the modified acrylic resin, anti-sedimentation agent, dispersant, and solvent into the container, and disperse for 20 minutes at a speed of 1200 rpm with a high-speed disperser , add pigments and fillers to disperse at high speed for 40 minutes, grind, control the fineness to no more than 20 μm, then add light stabilizer, wear-resistant additive, leveling agent to the ground paint, disperse at high speed for 45 minutes, mix evenly, and finally add some solvent to adjust Viscosity reaches 90s, that is, the A component that meets the requirements is obtained; the preparation of B component: mix the polyether-modified polycyanate prepolymer and the aliphatic isocyanate multimer evenly, that is, the B component that meets the requirements is obtained. Components: When using, mix A and B components according to the molar ratio of OH ...

Abstract

The invention discloses a multifunctional modified crylic acid polyurethane rubber coating and a preparation method thereof. The coating comprises two components, wherein organic silane modified acrylic resin and polyester modified acrylic resin are taken as film formation components, and polyether modified diisocyanate prepolymer and aliphatic series isocyanate polymer are taken as curing agent. The coating has excellent combination properties, such as adhesive force, gloss, richness, distinctness of image, weather resistance, abrasive resistance, high low temperature resistance, flexibility, solvent resistance, and stain resistance. According to the coating, the bottom and the surface are combined, so that a primer does not need to be sprayed, the technology is simple, the energy for construction is saved, and the efficiency is improved.

Description

technical field [0001] The invention relates to a rubber paint and a preparation method, in particular to a multifunctional modified acrylic polyurethane rubber paint and a preparation method. Background technique [0002] Rubber is an elastomeric material. With the development of the national economy and the development of the rubber industry, the application of rubber and rubber products continues to expand. At the same time, people have higher and higher requirements for the comprehensive performance of rubber and rubber products, such as performance, protection performance, decoration performance and various special functions. In order to achieve the high-demand comprehensive performance of rubber and rubber products, it is necessary to apply a layer of coating to rubber and rubber products. At present, some rubber coating products have been reported in China. However, the comprehensive properties of domestic rubber coating products such as gloss, fullness, distin...
