Abstract

The invention provides a matt finishing varnish and a preparation process thereof, and belongs to the field of stone-like coating materials, wherein the raw materials of the matt finishing varnish comprise, by weight, 25-40% of deionized water, 0-0.2% of a dispersing agent, 0.05-0.1% of a wetting agent, 2.5-6% of a matting material, 0.1-0.2% of an antifoaming agent, 50-65% of an emulsion, 2-5% of a film-forming auxiliary agent, 0.1-0.3% of a sterilization agent, 1-6% of an antifouling agent, and 0.2-0.5% of a thickening agent. The preparation process comprises: sequentially adding the raw materials to a material mixing barrel according to the formula to obtain a mixed material; and carrying out evacuation and gas bubble removing on the mixed material, and adding the thickening agent to obtain the matt finishing varnish. According to the present invention, with the matt finishing varnish, the contaminants can be easily removed, the occurrence of the rain mark can be avoided, and the hydrophilic self-cleaning effect can be achieved.

Description

technical field [0001] The invention relates to the field of imitation stone coatings, in particular to a matte finish varnish and a preparation process thereof. Background technique [0002] At present, the surface of imitation stone paint (real stone paint, rock flake paint, etc.) is rough after spraying. The textured surface of stone gives people a simple, low-key and generous feeling. However, the stone-like paint surface has a more obvious graininess and is prone to accumulate dust. [0003] After the emulsion film is formed in the existing finish varnish, most of the polymer coatings formed are hydrophobic coatings. Since there are many unnatural pollutants in the air, especially the oily pollutants in the air pollutants gradually increase, they will Adsorbed on the surface of the polymer hydrophobic coating film, it is difficult to be washed away by rainwater, and it is easy to leave unsightly rain marks. Contents of the invention [0004] The present invention p...
