Problems solved by technology

This type of canopy has a series of disadvantages. For example, PP glass fiber board or PU glass fiber composite board contains glass fiber material, which will cause harm to the skin of workers and the surrounding environment during processing; it is heavy and cannot meet the needs of automobiles. Lightweight requirements; the interface compatibility between polymer materials and inorganic non-metallic materials is very poor, and the molding performance is not ideal; the cross-linked and solidified PU foam in the PU glass fiber composite canopy cannot continue to be melted, and the glass fiber It can only be melted at a temperature above 1000°C, making the recycling of the PU composite canopy extremely difficult

Abstract

The invention relates to a manufacturing technology of a lightweight environment-friendly type automobile ceiling, and specifically relates to a manufacturing technology of an environment-friendly automobile ceiling used for reducing the automobile weight. The invention belongs to the technical field of automobile interior decorative part production. According to the invention, a surface material, a film and a foamed board are warmed by baking, and are subject to cold pressing and molding, such that the automobile ceiling is manufactured. The technology comprises steps of material paving, warming by baking, softening, molding by cold pressing, and water-jet cutting. With the technology provided by the invention, the lightweight environment-friendly type automobile ceiling is advantaged in light weight, good compatibility among materials, and easy molding and production. The automobile ceiling is environment-friendly. The produced rim leftovers can easily be recovered and reused. Therefore, application requirements of clients can be satisfied.

Description

technical field [0001] The invention relates to a manufacturing process of a lightweight and environment-friendly car roof, in particular to a manufacturing process of an environmentally friendly car roof capable of reducing the weight of a car, and belongs to the technical field of car interior parts production. Background technique [0002] The car roof is usually made of PP glass fiber board or PU glass fiber composite board as the base material, which is compounded with the surface blanket and PE film. This type of canopy has a series of disadvantages. For example, PP glass fiber board or PU glass fiber composite board contains glass fiber material, which will cause harm to the skin of workers and the surrounding environment during processing; it is heavy and cannot meet the needs of automobiles. Lightweight requirements; the interface compatibility between polymer materials and inorganic non-metallic materials is very poor, and the molding performance is not ideal; the ...
