Description

Scratch-resistant PVC (polyvinyl chloride) coated skin for vehicle Technical Field The utility model belongs to the technical field of PVC (polyvinyl chloride) coated skins, and particularly relates to a scratch-resistant automotive PVC coated skin. Background The PVC cladding epidermis is a surface coating layer which takes polyvinyl chloride (PVC) as a core material, is combined with a base material through a specific process, and is widely applied to the fields of decoration, automobiles and protection. The existing PVC coated skin for the vehicle has poor scratch resistance, and the friction force between the PVC coated skin and a hard object is increased instantaneously when the PVC coated skin is extruded by the hard object, so that the PVC coated skin is easily scratched along with the movement of the hard object, and abrasion and scratch are generated. Thus, a scratch resistant automotive PVC clad skin is proposed. Disclosure of Invention The utility model provides a scratch-resistant PVC coated surface skin for a vehicle, and aims to solve the problems. The embodiment of the utility model provides a scratch-resistant PVC cladding epidermis for a vehicle, which comprises an upper PVC matrix layer, a lower PVC matrix layer, an ABS resin layer, an elastic sleeve, an elastic brace, limit holes, brace caps, a graphene coating and an adhesion layer, wherein the upper PVC matrix layer is positioned below the lower PVC matrix layer, the ABS resin layer is arranged at the top of the upper PVC matrix layer, the elastic sleeve and the elastic brace are arranged between the upper PVC matrix layer and the lower PVC matrix layer, the elastic brace is positioned at the inner side of the elastic sleeve, the limit holes are respectively formed in the tops of the upper PVC matrix layer and the lower PVC matrix layer in a penetrating manner, the brace caps are respectively arranged at the top end and the bottom end of the elastic brace, the elastic brace penetrates through the limit holes, the graphene coating is coated at the top of the ABS resin layer, and the adhesion layer is arranged at the bottom of the lower PVC matrix layer. Further, eight elastic braces are arranged in total, the eight elastic braces are axially distributed at equal intervals in the same vertical line, and the elastic braces are arranged in an inclined state; Through adopting above-mentioned technical scheme, through eight slope elastic brace that set up, can form diversified buffering elastic layer between last PVC matrix layer and lower PVC matrix layer, when avoiding going up PVC matrix layer and receiving the scraping power of slope, go up the dislocation power grow and cause the problem of skew between PVC matrix layer and the lower PVC matrix layer. Further, the cross sections of the brace cap and the limiting hole are circular, and the outer diameter of the brace cap is larger than the inner diameter of the limiting hole; Through adopting above-mentioned technical scheme, avoid brace cap 7 to pass spacing hole, guarantee the stability that the elastic brace set up. Further, a strip-shaped groove is formed in the top of the ABS resin layer; through adopting above-mentioned technical scheme, can increase its area of contact with graphene coating through rectangular form recess, the firm coating of graphene coating of being convenient for is on the ABS resin layer.
