Problems solved by technology

The existing wet-process canopy is usually directly formed by superimposing glass fiber mat and PU. This molding process mainly has the following problems: 1. The glass fiber mat has already undergone a processing procedure in the glass fiber mat manufacturer, so it will produce The cost is higher than that of glass fiber of the same weight. Glue and rubber powder will be added in the processing of glass fiber mat manufacturers. Such substances will affect the odor and VOC of the product; 2. The glass fiber mat may be damaged during the molding process The complexity of the product shape leads to the appearance of the product with glass fiber marks, which leads to a decrease in the quality of the product appearance

Abstract

The invention relates to a wet-process production process of a sprinkled glass fiber roof, specifically for installation on the top of a car to play the roles of heat insulation, sound absorption and beautification, and belongs to the technical field of car interior parts. It obtains the finished glass fiber canopy through PU sheet rolling, laying, first glass fiber spilling, PU placement, second glass fiber spilling, fabric laying, pressing molding, cooling and setting, water jet cutting and inspection . The invention solves performance indicators such as low odor and low VOC of the roof, greatly reduces the weight of the roof, and meets the requirements of the lightweight design of the whole vehicle; when the glass fiber is scattered, the double-sided scattering process is adopted without any chemical composition Adding, forming flow operation, stable process, and good product appearance; the product has good rigidity, not easy to break and sag; there is no accumulation of semi-finished products on the way, which saves manufacturing costs; no harmful substances are produced in the entire production process of the product, which is an environmentally friendly product.

Description

technical field [0001] The invention relates to a wet-process production process of a sprinkled glass fiber roof, specifically for installation on the top of a car to play the roles of heat insulation, sound absorption and beautification, and belongs to the technical field of car interior parts. Background technique [0002] The car roof is generally installed on the top of the car to play the role of heat insulation, sound absorption 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, high strength, odor, and VOC of the canopy have become bottlenecks, restricting the development of the canopy. The...
