Embodiment 1

[0020] A leather treatment agent, comprising the following components by weight percentage: 25% sodium polyacrylate, 1% tripolyethylene glycol monododecyl ether, 1% sodium tripolyphosphate, 1% silver-loaded activated carbon and silver-loaded zeolite, 1% % nano titanium dioxide, 11% modified rapeseed oil, 25% amphoteric acrylic retanning agent, 35% water. The dosage ratio of silver-loaded activated carbon and silver-loaded zeolite is 1:1.

[0021] The preparation method of the above-mentioned modified rapeseed oil is as follows: add yeast to the rapeseed oil, heat up at a heating rate of 5°C / min after fully mixing, keep warm and mix for 2min after the temperature rises to 178-185°C, and then heat at 10°C / min Cool down at a cooling rate of 1 min. After the temperature drops to 28-35°C, keep it warm for 30 minutes and pass through a 400-mesh sieve. Then add cationic polyacrylamide, mix thoroughly and let stand for 1 hour, then increase the temperature at a rate of 10°C / min. Rais...

Embodiment 2

[0024] A kind of leather treatment agent, similar to Example 1, the difference is that it comprises the following components in weight percentage: 30% sodium polyacrylate, 3% emulsifier, 3% sodium tripolyphosphate, 3% silver-loaded thing, 3% Nano titanium dioxide, 10% modified rapeseed oil, 20% amphoteric acrylic retanning agent, 28% water.

[0025] The emulsifier is tripolyethylene glycol monododecyl ether.

[0026] The silver-loaded substance is silver-loaded activated carbon and silver-loaded zeolite. The dosage ratio of silver-loaded activated carbon and silver-loaded zeolite is 1:1.

Embodiment 3

[0028] A kind of leather treatment agent, and embodiment 2 is similar, and difference is, comprises the component of following percentage by weight: 31% sodium polyacrylate, 3% emulsifying agent, 2% sodium tripolyphosphate, 2% silver-loaded thing, 2% Nano titanium dioxide, 10% modified rapeseed oil, 20% amphoteric acrylic retanning agent, 30% water.

Abstract

The invention discloses a leather processing agent. The leather processing agent comprises, by weight, 25-35% of sodium polyacrylate, 1-4% of an emulsifier, 1-4% of sodium tripolyphosphate, 1-4% of asilver loaded product, 1-4% of nano titanium dioxide, 5-15% of modified rapeseed oil, 15-25% of an amphoteric acrylic acid retanning agent, and 25-35% of water. The leather processing agent is used inthe fields of textile industry, leather or furry product industry, is capable of providing leather with antibacterial performance, mildew resistance, tightness, uniform dyeing degree, high dye uptake, high solvent resistance, and high grease resistance, so that using requirements can be satisfied.

Description

technical field [0001] The invention relates to a leather treatment agent. Background technique [0002] Leather products are durable, elegant and comfortable, and are widely used in clothing, shoes, bags, fixtures and other industries. As the earliest raw material in the natural leather industry, it has excellent ecological characteristics and is widely used. With the growth of the world's population and the rapid development of the economy, the human demand for leather has doubled, and natural leather can no longer meet people's normal needs. Artificial leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. Leather surface treatment agent is a process method of artificially forming a layer of different...
