Description

Wear-resisting PU synthetic leather

Technical Field

The utility model relates to a synthetic leather technical field, in particular to wear-resisting PU synthetic leather.

Background

PU synthetic leather has been increasingly used and is increasingly accepted by the market because of its superiority in overall properties. The traditional PU synthetic leather adopts PU resin of an organic solvent as a surface layer and a base layer material for producing the synthetic leather. The PU resin is prepared by taking toluene, xylene, acetone, butanone, ethyl acetate, dimethylformamide and the like as main solvents, and most of the solvents have great toxic and side effects, so that the PU resin not only causes environmental pollution, but also is flammable and explosive, and is very easy to cause fire accidents. Therefore, the environment-friendly synthetic leather product replaces the traditional synthetic leather and becomes the inevitable trend of industrial development.

The PU synthetic leather is widely used for decorating bags, clothes, shoes, vehicles and furniture, friction is generated in the using process, and the synthetic leather is required to have certain friction resistance, so that the wear resistance is increased, the situation that the elasticity and the toughness of the synthetic leather are deteriorated is easily caused, the using effect is influenced, and the service life is also influenced.
