Abstract

The invention discloses a special high-gloss anti-fouling and wear-resistant water-based paint for PVC surface decoration and a preparation method thereof. High-gloss anti-fouling and wear-resistant water-based coatings for PVC surface decoration include polycarbonate-based water-based polyurethane emulsion, water-based anti-fouling agent, water-based curing agent, water-based wetting agent, water-based defoamer, water-based leveling agent, etc. The special coating of the invention is friendly to the environment and has strong adhesion, and solves the damage to the coating caused by the precipitation of the plasticizer dioctyl phthalate during the printing process of the PVC substrate. The coating of the present invention uses an amino-based water-based resin crosslinking agent as a curing agent, and is printed at room temperature, and the formed coating can achieve good adhesion fastness, water resistance, and anti-blocking properties, and can be passed in the subsequent decorative panel bonding process. 150 ℃ ~ 180 ℃ fit the tank, the curing agent contained in the coating will undergo a cross-linking reaction, and finally form a high-gloss anti-fouling and wear-resistant water-based coating with a gloss of ≥ 90 degrees and a hardness of ≥ 2H, which increases wear resistance, alcohol resistance, and water resistance. characteristics such as pollution.

Description

technical field [0001] The invention relates to a water-based paint, in particular to a special high-gloss anti-fouling and wear-resistant water-based paint for PVC surface decoration. Background technique [0002] With the improvement of people's living standards and the emergence of a large number of commercial housing, hotels and exhibition halls, people's requirements for interior decoration materials continue to increase. The furniture coated with PVC surface decoration has been widely used due to its good decorative effect. [0003] The surface coating of furniture coated with PVC surface decoration mainly plays the role of anti-fouling and friction resistance. The traditional PVC surface coating uses organic solvents as the dispersion medium. Some organic solvents such as formaldehyde will still remain, and long-term exposure will cause harm to the human body, and even cause chronic poisoning. [0004] Water-based paint is a polymer material that uses water instead ...
