Abstract

The invention discloses artificial leather for automotive trim and a preparation method thereof, belongs to the field of artificial leather manufacturing, and solves the problems that artificial leather for automotive trim in the prior art is poor in wear resistance and a coating is easy to fall off. The artificial leather is base-cloth-free artificial leather, the artificial leather sequentially comprises the PVC foaming layer, the resin layer and the surface treatment layer from bottom to top, the problem that the base cloth layer and the leather layer are easy to peel off is solved, the artificial leather sequentially comprises the PVC foaming layer, the resin layer and the surface treatment layer from bottom to top, the wear resistance of the artificial leather is improved, and the service life of the artificial leather is prolonged. However, due to the fact that the wear resistance needs to be improved, the film forming hardness of the PVC artificial leather is large, the problem that after the hardness of the artificial leather is increased, the buckling resistance is reduced at the low temperature is solved, the softness and comfort of the artificial leather are kept, and the experience feeling of the artificial leather applied to automobile interiors can be improved.

Description

technical field [0001] The invention belongs to the field of artificial leather manufacturing, in particular to an artificial leather used for automobile interior decoration and a preparation method thereof. Background technique [0002] With the development of the economy, the demand for automobiles has also increased rapidly. With the growth of automobile production, automobile interior materials are also developing rapidly. When purchasing a car, consumers not only pay attention to the functions, safety and exterior styling of the car, but more and more consumers have higher and higher requirements for the durability and comfort of the interior. Therefore, in the field of interior design, new requirements are placed on the durability and comfort of interior products. Leather materials are essential in car interiors, and the demand for leather is not limited to genuine leather. Various simulation products can already replace some genuine leather products. [0003] PVC ar...
