Problems solved by technology

However, organic or inorganic matting powder has a rough or too slippery feel, poor compatibility with the main film-forming resin, poor wear resistance, poor scratch resistance, and poor chemical resistance.
[0004] Pure water-based large particle size self-dulling polyurethane resin has extremely low matteness and excellent black haze. It does not need to add any matting agent in the system, and the products obtained by using it have a good suede and soft touch, and have great application prospects in plastic products. , however, it also has certain defects, such as poor adhesion, poor scratch resistance, poor wear resistance, which limits its application

Abstract

The invention belongs to the technical field of water-based plastic paints, and provides a water-based composite resin composition, a water-based plastic paint and a preparation method of the water-based plastic paint. The water-based composite resin composition is prepared by adopting the following components in percentages by weight: 70-90wt% of water-based large-particle-size polyurethane resinwith the particle size of 800-2000nm, 6-25wt% of water-based acrylic resin, and 2-8wt% of an auxiliary agent; and the water-based plastic paint is prepared by adopting the following raw materials inparts by weight: A, 100 parts of the above water-based composite resin composition, and B, 2-6 parts of a water-based isocyanate curing agent. According to the method provided by the invention, compounding of the water-based large-particle-size polyurethane resin and the water-based acrylic resin is adopted, so that the plastic paint has excellent adhesion, scratch resistance, abrasion resistance,chemical resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of water-based plastic paint, and in particular relates to a water-based composite resin composition, water-based plastic paint and a preparation method thereof. Background technique [0002] Water-based environmentally friendly polyurethane paint does not contain organic solvents, is non-toxic, easy to use, and its physical and chemical properties can achieve the effect of solvent-based coatings. Therefore, water-based environmentally friendly polyurethane paints are increasingly used in textile coatings, leather finishing, and industrial coatings. Being valued is the trend of future industry development. [0003] In addition, products with matte surface materials are more and more popular. At present, in the formulation of matte materials, directly adding matting powder is still the most widely used method. However, organic or inorganic matting powders have a rough or slippery feel, poor compatibility wi...
