Abstract

The invention relates to a method for producing a sunroof window visor for an automobile. The method comprises the following steps: substrate PU material pretreatment, sunroof window visor material combination and laying, pressure molding, cooling shaping and waterjet cutting, and the step of substrate PU material pretreatment comprises a substep of rubber rolling and a substep of softened water spray. The method solves the problems of performance indices of sound absorption, heat resistance, light weight and high strength of a sunroof window visor assembly; the weight of the sunroof window visor is greatly reduced, and the requirement on lightweight design of a complete automobile is met; during the PU material pretreatment process, the flow operations of heating of the double-sided PU rolled rubber and softened water treatment are adopted, the technology is stable, the operation security and accuracy are guaranteed, and simultaneously, the operation efficiency is improved; the rigidity of the product is high, without break and sagging; the stack of half-finished products can not happen during the process, and thus the production cost is saved; no harmful substance is generated during the entire production process.

Description

technical field [0001] The invention relates to a production method of an automobile sunroof sunshade, in particular to a sunroof mechanism installed on the top of a sunroof type automobile, which plays the role of heat insulation, sound insulation and beautification, and belongs to the technical field of automobile interior parts. Background technique [0002] The car sunroof sunshade is installed on the sunroof mechanism on the top of the sunroof car, which plays the role of heat insulation, sound insulation and beautification. In the era of more and more pursuit of high performance, environmental protection, energy saving, lightweight, and individualization, the interior of a car, like the shape of a car, has become an important factor for people to choose a car. Therefore, the requirements for automotive interior parts are getting higher and higher. In the prior art, performance indicators such as high sound absorption, low weight, and high strength of sunroof sunshades...
