Plastic material based on high-wear-resistance water-based elastic coating

Abstract

The invention discloses a plastic material based on a high-wear-resistance water-based elastic coating. The plastic material is composed of a plastic substrate and a coating layer on the surface of the plastic substrate. The coating layer is prepared from the high-wear-resistance water-based elastic coating; the high-wear-resistance water-based elastic coating comprises an agent A and an agent B;the agent A comprises water-based polycarbonate polyurethane, water-based polyether polyurethane, water-based hydroxy acrylic acid, a neutralizer, a water-based dispersing agent, a water-based wettingleveling agent, a water-based defoamer, a water-based thixotropic agent, water-based wax slurry and deionized water; and the agent B comprises a curing agent and a diluent. According to the formula,the matte effect is achieved, the required matte effect can be achieved by adding little or even no matting powder into an elastic paint system, the matting stability of the system is better, the permeability of a paint film is good, the three kinds of resin serve as main bodies and are combined with a small amount of auxiliaries, and the effects that the paint film has the high abrasion resistance and meanwhile the hand feeling is excellent are achieved.

Description

technical field [0001] The invention belongs to the technology of composite plastics, in particular to plastic materials based on high wear-resistant water-based elastic coatings. Background technique [0002] Prior art CN106221339A A wear-resistant water-based elastic paint developed in a wear-resistant and scratch-resistant water-based elastic paint is used in metal materials with excellent wear resistance, but the handle is hard, and the wear resistance and feel cannot be balanced, and the wear-resistant and good feel Harder, good feel and poor wear resistance. The prior art contains a coating on the surface of the TPU film. The coating is a hardened elastic coating or a super-hydrophobic coating. A protective film is attached to the surface of the coating. The protective film is a back-adhesive plastic film or a multi-layer co-extruded film. , Electrostatic adsorption film, the peeling force between the protective film and the coating is 0.05 ~ 10N / 25mm, the protective ...

Problems solved by technology

[0003] The invention discloses a plastic material based on a high wear-resistant water-based elastic coating. The main material of the coating on the surface of the plastic base is water-based polycarbonate polyurethane, water-based polyether polyurethane, water-based hydroxyacrylic acid and other water-based resins, which avoids the oil-based elastic coating system. Contains a large amount of organic solvents, the diluent is also an organic solvent, VOC is not up to the standard, and it is not environmentally friendly; it solves the problem that the existing water-based plastic elastic coatings cannot be balanced in wear resistance and hand feel. bad question
