Problems solved by technology

However, there are also some defects in the above inventions, such as: CN 101618698A uses honeycomb paper core as an interlayer, which has insufficient rigidity as a ceiling material; in CN 102050062A, a special adhesive film and fiber mat need to be prepared first, and the production cost increases accordingly. It is not conducive to production automation; the production process of CN 101856870A is relatively complicated, and the PU two-component raw material is used for spraying, which will pollute the environment, and the glass fiber felt with a "sandwich" structure and the cardboard with a hollow structure are used for mold clamping and pressure retention , PU foam forming, the processing process is difficult to control

Abstract

The invention belongs to the technical field of high polymer materials and discloses a light composite board which can serve as automotive interior parts, a production method and application thereof. The light composite board is prepared from the following components in percentage by mass: 30-70 percent of polyolefine fiber and 30-70 percent of glass fiber. The invention also discloses a method for manufacturing a ceiling of the automotive interior part from the light composite board. The method comprises the following steps of: cutting the light composite board according to the required size, and removing slitter edges to obtain a ceiling framework; heating to the temperature of 170-220 DEG C, and laminating a facing layer to obtain a thickened decorative ceiling framework; performing mold pressing by a corresponding mold at normal temperature, wherein the pressure is 0.05-0.5MPa, and the mold pressing time is 20-40 seconds; and removing the excessive facing layer, trimming the side hole burrs, and checking and warehousing to obtain the ceiling of the automotive interior part. The invention also discloses a method for manufacturing a protective bottom plate of the automotive interior part from the light composite board. The light composite board is excellent in comprehensive performance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a light-weight composite plate that can be used as an automobile interior decoration, a production method and an application thereof. Background technique [0002] With the rapid development of the world economy and the continuous improvement of people's lives, the automobile industry is developing rapidly, and the production of cars is also changing with each passing day, and the car models are constantly updated. People's requirements for cars are not only the beautiful appearance, but also the comfort, integrity and functionality of the interior decoration. This requires the materials of automobile interior parts to be heat-insulating, noise-absorbing, shock-proof, flame-retardant, beautiful and practical. and other performance. [0003] The roof and side rear panel are important parts of the interior panels of the car. Their functions are to decorate the interior spa...
