Abstract

The invention provides a novel polyurethane extinction glass oil. The novel polyurethane extinction glass oil comprises the following compositions in parts by weight: 10 to 30 parts of isopropanol, 0.1 to 0.5 part of a PH modifier, 70 to 100 parts of polyurethane, 0.1 to 0.5 part of a dispersing agent, 2 to 5 parts of organosilicone extinction powder, 0.1 to 0.5 part of an antifoaming agent, 0.1 to 0.5 part of wax powder, 5 to 10 parts of a feeling agent, 2 to 6 parts of a thickening agent, and 30 to 50 parts of water. The extinction glass oil has an anti-settling effect, the yellowing resistance is good, the extinction material does not gather, the extinction glass oil cannot become white during spraying, and the blackness is good; in addition, the hand feeling is good, and the moist, soft and comfortable wax feeling is achieved.

Description

technical field [0001] The invention belongs to the field of leather chemical industry, and in particular relates to a novel polyurethane matting varnish. Background technique [0002] A resin coating layer is formed on the leather surface, which not only makes the leather surface oil-resistant and sweat-resistant, but also protects the leather grain and beautifies the leather surface. Polyurethane resin is a common material for leather finishing. It is mainly used for top coating. It has excellent adhesion, softness, transparency, bending resistance, low temperature resistance, chemical resistance, heat resistance and abrasion resistance. It is the most widely used . [0003] Polyurethane top coating is mainly divided into high gloss and matte according to its brightness. Matting is an essential product to meet the different needs of people. At present, there are relatively few methods for this new type of matting varnish, and the product positioning is also uneven. Due...
