Abstract

The invention discloses an elastic fuzz polyurethane paint which is prepared by evenly mixing a component A, a component B and a component C in weight ratio, wherein the component A is prepared from elastic polyurethane resin, fuzz slurry, a dispersant, nano prepolymer, a leveling agent and the balance of a diluter; the component B is prepared from HDI (hexamethylene diisocyanate) tripolymer polyisocyanate, HDI-TDI (toluene diisocyanate) tripolymer and butyl acetate; and the component C is prepared from butyl acetate and propylene glycol monomethyl ether acetate. Compared with similar paints on the market, the invention has the following advantages: 1. by selecting optimal elastic resin, the elastic fuzz polyurethane paint feels more elastic and looks more fuzzy; 2. the elastic fuzz polyurethane paint is preferably compounded from inert pigment mica powder, fuzz powder and nano materials, thereby having the advantages of weather resistance, scoring resistance, water resistance, anti-static property and high surface gloss; and 3. the elastic fuzz polyurethane paint has great construction tolerance, thereby enhancing the painting efficiency.

Description

technical field [0001] The invention relates to a functional coating of polymer materials, in particular to an elastic fluffy polyurethane coating. Background technique [0002] With the development of industry and the improvement of people's living standards, polymer materials are widely used in the coating industry. Polyurethane coating is also used as one of them, because of its good performance and increasing output. [0003] As a functional paint, "velvet paint" refers to a highly decorative paint with a "fluffy effect" such as the soft, soft, slippery feel of fabrics and suede that people feel visually and tactilely. Velvet paint was first developed by Japan's Musashi Paint Company in 1971 because of its good decorative and protective effects. It gives people a comfortable feel and soft, advanced visual experience, so it has been greatly developed in the coatings industry as a high-performance and high-decorative coating. Since 1992, Japan's Riyu Sheng Industry Co.,...
