Abstract

The invention discloses special graining resin for treating the leather surface and a manufacturing method thereof. The special graining resin for treating the leather surface comprises the following compositions: 80 to 120 portions of PU, 35 to 50 portions of CP, 35 to 50 portions of butyl acetate, 40 to 60 portions of dimethyl formamide and 40 to 60 portions of butanone. The manufacturing method comprises the following technological steps: 1) the butyl acetate, the dimethyl formamide, the CP and the PU are stirred for 10 minutes according to the mixture ratio; and 2) the butanone is added into the mixture and stirred for 2 minutes, and the finished product can be obtained. The special graining resin for treating the leather surface has the advantages that the requirements of abrasion resistance, scraping resistance, flection resistance, color fastness and so on meet the international standards; water resistance, moisture permeability, water pressure resistance, solvent resistance, strong acid and strong alkali resistance, external moisture variation resistance and moisture variation resistance meet the standards; and the oily light sense is strong and permanent.

Description

Technical field: [0001] The invention relates to a treatment agent for leather surface, in particular to a special embossing 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, poor color fastness, oily and smooth, weak and not durable, so it is necessary to match a special kneadi...
