Description

technical field

[0001] The invention relates to a composite material for automobile interior trim skin and its preparation method and application. Background technique

[0002] In the prior art, automotive interior skin composite materials usually use polyurethane automotive flame composite sponges and fabrics or leather composites to be used in automotive interiors; polyurethane automotive flame composite sponges can be mainly divided into polyether sponges and polyester sponges. , The production process of polyether sponge is simple, its performance is slightly worse than that of polyester sponge, and its cost is lower. It is mainly used in low-end models; the production process of polyester sponge has high requirements for equipment, and the produced sponge has good performance and high price. Mainly used in high-end models.

[0003] At present, the flame composite sponge with the largest amount on the market is polyether polyurethane sponge, that is, the main raw materi...
