Problems solved by technology

[0005] Compared with the many advantages of water-based acrylic coatings, water-based acrylic coatings also have the following disadvantages: poor wear resistance, poor dispersion stability against strong mechanical forces; in addition, water-based acrylic coatings have a large latent heat of evaporation for water and consume energy for baking Large, the paint needs to be baked at high temperature, and it takes a long time to completely dry, which greatly limits its application

Abstract

The invention discloses a fast-curing high-wear-resistance impact-resistance water-based acrylate coating material, which is prepared from the following raw materials in parts by weight: 60 to 75 parts of waterborne polyurethane modified acrylate composite emulsion, 45 to 55 parts of a modified silicon dioxide doped trifluoroethyl methacrylate solution, 35 to 50 parts of a pigment filler, 1.5 to 2.5 parts of a film forming aid, 0.8 to 1.5 parts of a defoaming agent, 0.4 to 0.6 part of a leveling agent, 0.6 to 1.2 parts of a wetting agent, 3 to 5 parts of a cosolvent and 32 to 48 parts of deionized water. According to the invention, waterborne polyurethane modified acrylate composite emulsion and a modified silicon dioxide doped trifluoroethyl methacrylate solution are used as film forming substances, so that the mechanical property of a final coating finished product is remarkably improved, and the impact resistance is greatly improved; and the fast-curing high-wear-resistance impact-resistance water-based acrylate coating material overcomes the defects of poor wear and impact resistance and low drying speed generally existing in water-based coating materials, can be widely applied to multiple fields, and has a good market prospect.

Description

technical field [0001] The invention belongs to the technical field of water-based coatings, and in particular relates to a preparation method of a fast-curing, high-abrasion-resistant and impact-resistant water-based acrylate coating. Background technique [0002] Water-based paint is a paint that uses water as a diluent and does not contain organic solvents. It does not contain benzene, toluene, xylene, formaldehyde, and free TDI toxic heavy metals. , crystal clear, good flexibility and has the advantages of water resistance, aging resistance, yellowing resistance, easy to use, etc., can be widely used in wood, metal, plastic, glass, building surfaces and other materials.
