Problems solved by technology

This makes it difficult to weld the PVC leather to the polyester fabric
Because the thickness of the polyurethane soft foam on the back of the polyvinyl chloride leather is 2.5mm, and there is a layer of non-woven fabric on the surface of the soft foam, so the prior art cannot realize the adhesion between the polyvinyl chloride leather and the fabric covered with polyurethane soft foam and non-woven fabric. High frequency heat sealing

Abstract

The invention relates to a composite interior trim plate of a passenger automobile and a production method of the composite interior trim plate and belongs to the technical field of automotive interior trim plate processing. The composite interior trim plate of the passenger automobile comprises a polyester shell fabric coated with polyurethane foams and non-woven fabrics, polyvinyl chloride leather coated with the polyurethane foams and the non-woven fabrics and a bastose material base plate, and the lapped edges of the polyester shell fabric coated with the polyurethane foams and the non-woven fabrics and the polyvinyl chloride leather coated with the polyurethane foams and the non-woven fabrics are welded into a layer structure by means of a high frequency heat-sealing mode. According to the composite interior trim plate of the passenger automobile and a production method of the composite interior trim plate, the polyester shell fabric coated with the polyurethane foams and the non-woven fabrics and the polyvinyl chloride leather coated with the polyurethane foams and the non-woven fabrics are welded in a high frequency hot-sealing mode to form an integrated member with a special trajectory, the characteristic line of the plate is clear and even, and the welding is firm.

Description

technical field [0001] The invention relates to a passenger car composite interior panel and a production method thereof, belonging to the technical field of automotive interior panel processing, in particular to the technical field of passenger car interior panel processing. Background technique [0002] In the production of automobiles, automotive interior panels play a role in beautifying the interior space of automobiles and improving functions. The surface of the existing automotive interior panels is mostly covered with the same fabric, but there are still problems in the joint coating of different fabrics. At the same time, in order to ensure the comfort of the automotive interior panels, the fabrics are mostly polyvinyl chloride leather and polyester fabrics, and the back is covered with polyurethane soft foam, generally with a thickness of 2-3mm. Difficulty arises. During the fabric covering process, PVC leather and polyester fabrics are also bonded to the substra...
