Description

Double-component high-gloss stain-resistant quick-drying floor scribing paint and preparation method thereof Technical Field The invention belongs to the technical field of floor marking paint, and particularly relates to a double-component high-gloss stain-resistant quick-drying floor marking paint and a preparation method thereof. Background The floor scribing can play roles of guiding, standardizing working areas, distinguishing different functional areas and the like, so that the floor scribing is widely applied to workshops, warehouses, garages and other places. Besides the performance requirements of good adhesive force, high gloss and quick drying with the floor, the floor scribing paint has higher performance requirements for different application scenes. In a food production workshop, steam jet cleaning and edible oil stain penetration are often faced, so that the pollution-resistant and steam jet-resistant requirements are also provided for floor scribing paint used by the food production workshop, and the problems of dirt, falling off and the like caused by floor scribing are avoided. The Chinese patent with the publication number of CN112795253A discloses a single-component acrylic road marking paint and a preparation method thereof, and the paint provided by the technical scheme comprises, by weight, 30-50% of a first acrylic emulsion, 2-20% of a second acrylic emulsion, 0.1-0.2% of cellulose, 0.5-1.0% of a dispersing agent, 0.1-0.3% of magnesium aluminum silicate, 1.5-2.0% of a defoaming agent, 0.8-1.2% of a functional auxiliary agent, 10-15% of titanium dioxide, 5-15% of barium sulfate, 5-10% of quartz powder, 0.5-1.0% of a leveling agent, 0.1-0.2% of a bactericide, 0.1-0.5% of a wetting agent, 3-4% of a film forming auxiliary agent, 0.5-1.5% of diethyl butyl ether, 0.1-0.5% of a scratch-resistant auxiliary agent, 0.1-1.0% of a thickening agent and the balance water, wherein the first acrylic emulsion is a T58 emulsion, and the second acrylic emulsion is a D640 emulsion.
