Leather lustering agent

Abstract

The invention relates to the technical field of leather care, in particular to a leather brightener. It consists of the following components by mass: 15-20 parts of rice bran wax, 10-15 parts of beeswax, 5-8 parts of polydimethylsiloxane, 10-15 parts of cetearyl polyoxyethylene ether, 12 parts 8-10 parts of sodium alkylbenzene sulfonate, 5-8 parts of tripolyglycerol sodium monostearate, 5-8 parts of silicone modified polyurethane resin, 5-10 parts of mineral oil, 3-5 parts of lanolin, hard 3-5 parts of fatty acid, 80-100 parts of water, 10-15 parts of isopropanol, 0.1-0.3 parts of benzyl alcohol, and 0.1-0.5 parts of methylchloroisothiazolinone. The leather brightener of the present invention contains vegetable wax and animal wax, and water is not easy to penetrate into the leather; small molecule fat and alcohol can penetrate deep into the leather fiber to replenish oil, making the leather plump and flexible; the silicone-modified polyurethane resin can A breathable film is formed on the surface of the leather, which is smooth to the touch, and can increase the brightness and wear resistance of the leather.

Description

technical field [0001] The invention relates to the technical field of leather care, in particular to a leather brightener. Background technique [0002] Leather products are products processed from fur and leather as the main raw materials, including boots, shoes, gloves, hats, bags, stationery and so on. Leather products are soft, tough, not easy to deform when exposed to water, not easy to shrink when dry, resistant to heat and humidity, and resistant to chemical agents, especially air permeability, vapor permeability and anti-aging performance. Although the performance of leather products is very good, it still needs regular maintenance, such as waxing or rubbing conditioner.

Although the performance of leather products is very good, it still needs regular maintenance, such as waxing or rubbing conditioner

[0003] There are two types of leather brighteners widely used at present. One is a general oil emulsifier, which can replenish leather oil, but the surface lightness is poor and not durable. After the oil penetrates into the leather, the surface becomes dull and dull; the other is It is aliphatic polyurethane, which is polymerized by introducing a cross-linking agent. Although the leather surface is bright, it lacks oil and cannot nourish the leather. It just forms a film on the surface of the leather, and this film affects the air permeability of the leather instead, making the original leather Reduced air permeability
