Abstract

The invention provides PVC skin capable of being used as a mold. The skin is sequentially prepared from PP foam cotton, a bottom layer, a face layer, and a surface layer from bottom to top, wherein the bottom layer is prepared from the following ingredients in parts by weight: 20 to 30 parts of TPU particles, 60 to 80 parts of PVC resin powder, 2 to 5 parts of stabilizing agents, 1 to 4 parts of plasticizers, 2 to 8 parts of foaming agents and 1 to 5 parts of fire retardants, the face layer is polyether urethane; the surface layer is prepared from the following ingredients in parts by weight:50 to 70 parts of polycarbonate water-based treatment agents, 3 to 8 parts of crosslinking agents and 1 to 6 parts of wear-resistant agents. The PVC skin capable of being used as a mold and a preparation method provided by the invention have the advantages that the method is simple and controllable; the repeatability is high; the PVC skin prepared by using the method can be directly used as a moldfor transferring surface patterns; the precision is high; the patterns can be precisely controlled; meanwhile, good physical performance is realized; the service life is long.

Description

technical field [0001] The invention relates to the technical field of automobile interior decoration, in particular to a PVC skin that can be used as a mold and a preparation method thereof. Background technique [0002] With the continuous improvement of automobile penetration rate, automobile lightweight, safety, comfort and environmental protection have become the main trends in the development of today's automobile industry. Substituting plastics for metals in automobile manufacturing is an important means for the automobile industry to achieve the above goals. The amount of plastic used in automobiles has also become one of the important indicators to measure the level of automobile production technology. Polyvinyl chloride, English name: polyvinylchloride, referred to as PVC, is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator, and is a homopolymer of vinyl chloride. Vinyl chloride homopolymers and vinyl chloride copolymers are col...
