Abstract

The invention discloses high-light anti-fouling wear-proof water-based paint special for PVC surface decoration and a preparation method thereof. The high-light anti-fouling wear-proof water-based paint special for the PVC surface decoration comprises polycarbonate-type waterborne polyurethane emulsion, a water-based anti-fouling agent, a water-based curing agent, a water-based wetting agent, a water-based defoaming agent, a water-based flatting agent and the like. The special paint is environment-friendly, strong in adhesive force, and capable of solving a problem that the paint is destructedby precipitation of a plasticizer of dioctyl phthalate in a printing process of a PVC base material. The paint is capable of using an amino water-based resin cross-linking agent as the curing agent,and printed in a normal temperature condition. A formed coating has good adhesion fastness, water resistance and adhesion resistance. In a follow-up pasting technology of a decoration faceplate, and through a pasting cylinder in 150-180 DEG C, the curing agent contained in the paint generates a cross-linking reaction, and finally the high-light anti-fouling wear-proof water-based coating of whichglossiness is greater than or equal to 90 degrees and hardness is greater than or equal to 2H is formed, so the characteristics of wear resistance, alcohol resistance, anti-fouling and the like are increased.

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 ...
