Abstract

The invention discloses a coke scraping resin for treating the surface of leather and a manufacturing method. The coke scraping resin comprises the following compositions in weight portion: 80 to 120 portions of PU, 35 to 45 portions of dimethylfomamide, 75 to 85 portions of acetone, 75 to 85 portions of butyl acetate, 10 to 18 portions of polypropylene wax, 3 to 7 portions of fine silicon dioxide, 0.5 to 1.2 portions of methyl organosilicon and 1 to 4 portions of fatty alcohol(C-16); the process comprises the following steps: (1) according to mixture ratio, the acetone, the butyl acetate, the dimethylfomamide, the fine silicon dioxide, the polypropylene wax and the fatty alcohol are stirred for 5 minutes; and (2) the PU resin and the methyl organosilicon are added into the mixture and are stirred for 8 minutes. The coke scraping resin for treating the surface of the leather has the advantages that the wearing resistance, scratch resistance, flexing resistance, color fastness and other requirements of the resin reach the national standard; water drenching resistance and water pressure resistance reach the standard; the solvent resistance and strong acid and alkali resistance reach the standard; the external wetting variation resistance and temperature variation resistance reach the standard; and the coke scraping resin has strong and lasting unctuosity and light perception.

Description

Technical field: [0001] The invention relates to a treatment agent for leather surface, in particular to a scorching resin for leather surface treatment. Background technique: [0002] At present, leather products such as clothing, luggage, decoration, packaging, military leather and other surface treatment methods are various, including color-changing crazy horse, high-solid cracking, high-solid ironing, bright surface treatment agent, matte surface treatment agent, cracking Scorching, bright crystal high solid, etc., among which the surface gloss technology is relatively mature and popular, such as various existing bright surface treatment agents, bright crystal high solid, high solid ironing. However, the leather surface is easy to change color, not easy to withstand high temperature, not wear-resistant, not scratch-resistant, not resistant to twists and turns, and has poor color fastness. Contents of the invention [0003] The technical problem to be solved by the pre...
