Easy-to-clean powder coating and production process thereof

Abstract

The invention discloses an easy-to-clean powder coating and a production process thereof. The easy-to-clean powder coating is prepared from the following raw materials in parts by weight: 400-600 parts of hydroxyl-terminated polyurethane resin, 150-400 parts of fluorocarbon resin, 10-40 parts of modified nano silicon dioxide, 2-10 parts of graphene, 120-150 parts of titanium dioxide, 60-70 parts of barium sulfate, 8-10 parts of leveling agent, 8-10 parts of wetting accelerator, 3-5 parts of benzoin, 1 part of pigment carbon black, 0.5 part of phthalocyanine blue and 2 parts of iron oxide yellow. The production process comprises the following specific steps: S1, premixing all the components of the polyurethane powder coating according to the proportion to obtain a mixed material; and S2, the mixed material obtained in the step S1 is subjected to melt extrusion, tabletting crushing and crushing and passes through a 180-mesh sieve, the self-cleaning powder coating with excellent weather resistance is formed, the coating has good weather resistance and pollution resistance, the raw materials are cheap and easy to obtain, special manufacturing is not needed, and the preparation processis simple.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to an easy-to-clean powder paint and a production process thereof. Background technique [0002] With the increasing air pollution and dust pollution, the road guardrails in the city and the surface coating of advertising display boards are suffering from more and more serious erosion. These require constant cleaning to ensure the cleanliness of the coated surface and the cleanliness of the entire city. This process requires a lot of manpower and material resources. In addition, most of the current household range hoods are powder coated, and the surface of the metal dining table is also powder coated. Due to the use of ordinary indoor powder coatings, oil stains require frequent cleaning processes, which not only wastes water resources, but also consumes a lot of manpower. Therefore, the use of easy-to-clean powder coatings has become an inevitable choice. Its main fun...

Problems solved by technology

[0004] As people's requirements for coatings are increasing day by day in daily life, the surface of the current powder coating is easily damaged after repeated wiping. After the surface is damaged, stains and dust will enter the microscopic gaps on the surface, making it difficult to clean. , silicone resin is very polluting to other materials, and there is an urgent need for an easy-to-clean powder coating with high surface hardness and difficult to be damaged by repeated wiping, and to develop an easy-to-clean powder coating that is easy to control the preparation process and has no pollution powder coating preparation process
