Abstract

The invention discloses silencing and noise-reducing PU leather which successively comprises a base cloth layer, a PU layer and a coating layer. An adhesive layer is arranged between the base cloth layer and the PU layer, the adhesive layer is made from a solvent-free PU adhesive, the coating layer is an aqueous coating layer, the PU layer comprises two PU single layers, and the PU layer is prepared from the following raw materials in parts by weight: 85-110 parts of PU resin, 60-70 parts of DMF, 12-18 parts of acetic ether and 20-32 parts of color paste. According to the silencing and noise-reducing PU leather and a preparation method thereof, the noise problem of the PU leather and other trim materials in a using process can be alleviated, so that a passenger has a high-end layered texture and silent comfort experience.

Description

technical field [0001] The invention relates to the field of artificial leather, in particular to a sound-absorbing and noise-reducing PU leather and a preparation method thereof. Background technique [0002] The special performance and feel of leather make it synonymous with "high-end" in the decoration of bags, clothing, shoes, vehicles and furniture, and has been fully affirmed by the market. Many, incalculable. Due to the long production cycle and limited quantity of natural leather, artificial leather has become its substitute, and there are many types of artificial leather, and high-grade artificial leather is even more expensive than genuine leather. [0003] PU artificial leather is the epidermis of polyurethane composition, which is suitable for various decorations instead of genuine leather, with good shaping effect and bright surface. The manufacture of general PU leather includes base fabric treatment, rubber preparation, coating, lamination, surface treatment...
