Abstract

The invention relates to a production method of an automobile skylight slide plate made of a paper honeycomb-shape core material, and belongs to the technical field of automobile interior trim part. A lightweight, vibration resistant, heat insulating and sound insulating automobile skylight slide plate with high specific strength, high stiffness-to-density ratio and good weatherability is prepared. The skylight slide plate is prepared by selecting the paper honeycomb-shape core material as a base material, placing a layer of honeycomb paper board between two layers of glass fiber mats, carrying out double face polyurethane spraying and moulding. The preparation steps comprise paving materials, spraying polyurethane, compacting for moulding, cooling for fixing, installing silica gel pads, applying back glue fabrics and assembling accessories. The method of the invention solves defect of heavy weight of a traditional skylight slide plate and satisfies design requirement of lightweighting automobile; a product has high rigidity and will not break or deform; the whole production process adopts an automatic production line for one-time production, so as to substantially reduce worker labor intensity and increase working efficiency; the whole production process generates no harmful substance, therefore, the method is an environment-friendly method for producing the automobile skylight slide plate.

Description

technical field [0001] The invention relates to a method for producing a car sunroof skateboard with a paper honeycomb core material, and prepares a car sunroof skateboard with light weight, high specific strength, high specific stiffness, good vibration resistance, heat insulation, sound insulation and weather resistance, which belongs to the automobile The field of interior technology. Background technique [0002] With the rapid development of China's auto industry, lightweight, low fuel consumption, high safety, reduced environmental pollution and reduced overall cost of automobile manufacturing and use have increasingly become the consensus of the automobile industry. Studies have shown that reducing vehicle weight is critical to improving fuel efficiency and reducing emissions. The weight of the vehicle is reduced by 56.69kg, and the mileage of the same 1L fuel vehicle can be increased by 0.09~0.21kg; at the same time, the mass of the vehicle is reduced by 50%, and th...
