Abstract

The invention discloses a super sub-skin-feeling wear-resistant water-based paint specially used for PVC surface decoration and a preparation method thereof. The coating contains ultra-matt water-based polyurethane emulsion, polycarbonate water-based polyurethane emulsion, water-based antifouling agent, water-based curing agent, water-based velvet agent, water-based wetting agent, water-based defoamer, water-based leveling agent, etc. The paint of the present invention adopts the ultra-matt water-based polyurethane emulsion as one of the two-component linking materials, and the formed coating has extremely low gloss, and does not need to add matting agent additionally. The coating of the present invention uses an amino-based water-based resin crosslinking agent as a curing agent. When printed at room temperature, the coating can achieve good adhesion fastness, water resistance, and anti-blocking properties, with a hardness ≥ 2H and a glossiness ≤ 2 degrees. Ultra-matte visual effect, velvet touch and skin-friendly, and added properties such as wear resistance, alcohol resistance, and stain resistance.

Description

technical field [0001] The invention relates to a water-based paint, in particular to a super-sub-skin-feeling 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. Furniture covered with PVC surface decoration has been widely used because of its good decorative effect. [0003] The surface coating of the furniture covered with PVC surface decoration mainly plays the role of anti-fouling and friction resistance. The traditional PVC surface coating uses organic solvent as the dispersing medium. The volatilization of the solvent not only causes air pollution and destroys the ecological balance, but also causes the printed product to dry after drying. There will still be some organic solvents such as formaldehyde remaining, and ...
