Embodiment Construction

[0009] It will be described in further detail below in combination with specific embodiments.

[0010] The novel interior ceiling and production process of the high-end car according to the present invention is made of thermoplastic polyurethane rigid foam board as the skeleton material, glass fiber as the reinforcement material, non-woven fabric and interior fabric as the composite material, and solid hot-melt adhesive The composite plate made of binder 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 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 Sta...

Abstract

The invention discloses a novel interior roof of a superior quality sedan and a production process, and belongs to the technical field of production of vehicle roof interior products. The novel interior roof is a composite board manufactured by taking a thermoplastic rigid polyurethane foam board as a framework material, glass fiber as a reinforcing material and solid hot melt adhesive as a bonding agent with a cold mold forming method. The production process comprises three major process steps of base material compounding, compression molding and finished product manufacturing in sequence. The novel interior roof has excellent performances of sound absorption, thermal insulation, self supporting, environment friendliness and the like, has extremely high rigidity and size stability and issuitable for design and manufacture of the roof of the superior quality sedan.

Description

technical field [0001] The invention relates to a novel interior ceiling of a high-end car and a production process thereof, and belongs to the technical field of processing and production of vehicle ceiling interior decorations. Background technique [0002] The skeleton materials of traditional automotive interior ceilings mainly use cardboard and PS boards, which are not easy to process and manufacture. The produced interior ceilings are easy to deform and absorb moisture. Low. Therefore, people look forward to a production process with stable process and high-performance automotive interior roof that can overcome the above-mentioned defects. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention proposes a novel interior ceiling for high-end cars and a production process. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a new type of int...
