Description

technical field [0001] The invention relates to a leather edge oil and belongs to the field of leather finishing agents. Background technique [0002] Leather products play a very important role in daily life, such as bags, belts, wallets, etc. are widely used in real life. These leather products generally need to be edge-sealed during the production process to cover up The problem of leather cuts and exposed edges after combination makes the product more beautiful and durable. Water-based polyurethane has the advantages of low-temperature folding resistance, good elasticity, and excellent film-forming properties. In the field of edge oil, it is often used alone or in combination with acrylic emulsion as a film-forming substance for edge oil. [0003] At present, there are problems such as bubbles, poor color fastness, intolerance to twists and turns, high and low temperature resistance, and too many solid and powder additives in the leather edge oil on the market. Therefor...
