Problems solved by technology

[0002] At present, there are many types of adhesives on the market, and there are many types of adhesives for leather (also called "adhesives"), most of which are solvent-based, but the use of organic solvents causes environmental pollution, and the volatilization of the solvents produces The gas is harmful to the health of production personnel
In the prior art, leather adhesives are still insufficient in terms of bonding strength and cannot meet the requirements of the market, and according to statistics, more than 92% of leather adhesives have poor weather resistance and insufficient waterproof and heat resistance and many other defects seriously affect the use of leather products, therefore, leather adhesives need to be improved urgently
