Problems solved by technology

[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 solids, etc. Among them, Crazy Horse technology is relatively mature and popular, but the leather surface is easy to change color, and it is not easy to withstand high temperature, not wear-resistant, scratch-resistant, twist-resistant and poor color fastness. So we need to mix a brand new crazy horse resin

Abstract

The invention discloses a wet wax crazy horse resin for treating the surface of leather and a manufacturing method thereof. The wet wax crazy horse resin comprises the following compositions in weight portion: 80 to 120 portions of PU resin, 60 to 100 portions of dimethylfomamide, 50 to 90 portions of toluene, 10 to 20 portions of wax powder, 3 to 7 portions of methyl organosilicon, 5 to 15 portions of hydroxyl organosilicon and 6 to 12 portions of acrylic powder; The process comprises the following steps: (1) according to mixture ratio, a toluene solution and a dimethylfomamide solution are mixed, are put to the wax powder and are fully stirred; (2) the methyl organosilicon and the hydroxyl organosilicon are stirred; (3) the mixture mixed in step two is put to a solution obtained in step one and is fully and evenly stirred for 8 minutes; and (4) the solution obtained in step three is added with the acrylic powder and is evenly stirred for 5 minutes to obtain the finished product. The wet wax crazy horse resin for treating the surface of leather and the manufacturing method have the following advantages: the wearing resistance, scratch resistance, flexing resistance, color fastness and other requirements of the resin reach the national standard; the resin solves the problems of discoloring of crazy horse, high-temperature embossing resistance and sizing time in the prior art; water drenching resistance and water pressure resistance reach the standard; the solvent resistance and strong acid and alkali resistance reach the standard; and the external wetting variation resistance and temperature variation resistance reach the standard.

Description

Technical field: [0001] The invention relates to a treatment agent for treating the surface of leather, in particular to a wet wax crazy horse resin for treating the surface of leather. Background technique: [0002] At present, leather products such as clothing, luggage, decoration, packaging, military leather, etc. have a variety of surface treatment methods, including discoloration crazy horse, high-solid cracking, high-solid burnishing, bright surface treatment agent, matte treatment agent, and cracking Scorching, shiny crystals, high solids, etc. Among them, the Crazy Horse technology is relatively mature and popular, but the leather surface is easy to change color, and it is not easy to withstand high temperatures, and is not abrasion-resistant, scratch-resistant, tortuous, and poor in color fastness. Therefore, it is necessary to match a brand new Crazy Horse resin. Summary of the invention [0003] The technical problem to be solved by the present invention is to address...
