Abstract

The invention discloses a solvent type skin-touch top-coat paint and a preparation method thereof. The paint is composed of a component A and a component B, the component A is prepared from 20 to 25 parts of straight-chain hydroxyl-containing polyester polyol resin, 5 to 8 parts of epoxy resin, 8 to 10 parts of hydroxyl vinyl resin, 1 to 1.5 parts of polyamide wax, 2 to 3 parts of polytetrafluoroethylene modified polyethylene wax, 3 to 4 parts of organic treated silicon dioxide, 3 to 4 parts of matting powder, 1 to 2 parts of wetting dispersant, 10 to 15 parts of methyl isobutyl ketone, 10 to 15 parts of ethyl acetate, 10 to 15 parts of methyl ethyl formylformate, 0.2 to 0.5 part of defoaming agent, 1 to 1.5 parts of slipping agent and 1 to 1.5 parts of slipping agent; the component B is prepared from 30 to 40 parts of toluene diisocynate tripolymer, 20 to 30 parts of hexamethylene diisocyanate tripolymer, 15 to 25 parts of butyl acetate and 10 to 20 parts of dimethyl carbonate. The coating has the characteristics of good texture, strong adhesive force, environmental protection and yellowing resistance.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a solvent-type skin-feeling clear topcoat and a preparation method thereof. Background technique [0002] Skin feel paint, originated in Italy, is the "blue blood nobleman" in furniture paint. The skin-feeling paint is named after the touch of the baby's skin. It has many advantages: smooth, slightly elastic, very low gloss, generally 2°-3°, very delicate surface, super strong texture, self-healing for slight scratches , Stain resistance, good scratch resistance. [0003] Traditional furniture lacquers are relatively dry to the touch, and their slipperiness is average. They feel dull to the touch, without elasticity and warmth. With people's focus and favor on the flexibility and smoothness of furniture products, traditional furniture paints cannot meet people's needs, especially in terms of texture, smoothness and elasticity, and skin-feeling paints can meet people's...
