Problems solved by technology

[0002] Traditional automotive interior ceilings, whose skeleton materials are mainly cardboard and PS boards, are not easy to process and manufacture. The produced interior ceilings are easily deformed, absorb moisture, and have poor sound absorption, heat insulation, rigidity, dimensional stability and environmental protection performance. It is a low-grade obsolete product that is not selected for modern passenger cars

Embodiment Construction

[0009] In order to better understand the present invention, it will be further elaborated below in conjunction with specific embodiments.

[0010] The passenger car interior ceiling of the present invention is made of thermoplastic polyurethane rigid foam board as a skeleton material, glass fiber as a reinforcing material, non-woven fabric and interior fabric as a composite material, and solid hot melt adhesive as a binder The composite plate made is processed by cold molding method, as follows:

[0011] First put the non-woven fabric on the workbench, spread solid hot-melt adhesive and glass fiber on the non-woven fabric, then place thermoplastic rigid polyurethane foam board (referred to as PU board) on it, and then spread it on the PU board Solid hot-melt adhesive and glass fiber, then heated to 150-260°C by a heating plate, and rolled and laminated under a pressure of 0.4-0.6mpa. The cooled composite sheet is the interior ceiling substrate, which is cut and stored Standby...

Abstract

The invention discloses a production process of a vehicle interior ceiling, in particular a production process of a passenger vehicle interior ceiling, belonging to the technical field of production of vehicle ceiling interior decorations, which uses thermoplastic polyurethane rigid foam board as a skeleton material, and uses Glass fiber is the reinforcing material, and the composite plate made of solid hot melt adhesive as the binder is made by cold molding method; its production process includes three major process steps of substrate compounding, compression molding, and finished product production. It has excellent performances such as sound absorption, heat insulation, self-support, and environmental protection, and has extremely high rigidity and dimensional stability, and is more suitable for the design and production of high-end car interior ceilings.

Description

1. Technical field [0001] The invention discloses a production process for a vehicle interior ceiling, in particular to a production process for a passenger vehicle interior decoration, and belongs to the technical field of vehicle ceiling interior decoration processing and production. 2. Background technology [0002] Traditional automotive interior ceilings, whose skeleton materials are mainly cardboard and PS boards, are not easy to process and manufacture. The produced interior ceilings are easy to deform, absorb moisture, and have poor sound absorption, heat insulation, rigidity, dimensional stability and environmental protection performance. It is an obsolete product that is low-grade and not used by modern passenger cars. 3. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned prior art, and disclose a production process for a high-grade passenger car interior ceiling with stable process and ex...
