Automotive interior wrapping material and automotive interior wrapping process

Abstract

The invention provides an automotive interior wrapping material and an automotive interior wrapping process. The wrapping material comprises a flexible material layer, a first carbon fiber layer, a sound-insulating PVC composite layer, a flame-retardant PVC composite layer, a second carbon fiber layer and a decoration layer from inside to outside sequentially, wherein the sound-insulating PVC composite layer is prepared with a method as follows: providing TiC powder; providing chlorosulfonated polyethylene rubber; performing thin-passing on the chlorosulfonated polyethylene rubber in a two-roll open mill 5-10 times; adding TiC powder to the two-roll mill, and performing mixing for 10-20 min to obtain a chlorosulfonated polyethylene rubber / TiC powder blend; mixing the chlorosulfonated polyethylene rubber / TiC powder blend, PVC particles and a processing aid in an internal mixer for 10-20 min to obtained a first mixed material; placing the first mixed material in the open mill to be prepared into a first sheet; performing first hot pressing on the first sheet to obtain the sound-insulating PVC composite layer. The automotive interior wrapping material has high strength, good sound insulation performance and good puncture resistance and flame retardance.

Description

technical field [0001] The invention relates to the technical field of layered materials, in particular to an automotive interior coating material and a coating process for the automotive interior. Background technique [0002] Interior parts generally refer to parts and materials such as partitions of car compartments, door trim panels, instrument panel assemblies, armrests, and carpets. Compared with other parts on the car, they have little effect on the running performance of the car, but they can be seen at a glance, represent the image of the whole car, determine the reputation and grade of the car, and determine people's intention to choose a car. In addition, for cars, although the interior parts are only some auxiliary parts, they have to undertake functions such as vibration reduction, heat insulation, sound absorption and sound insulation, which play a very important role in the comfort of cars. [0003] Automotive interior parts are generally formed by coating de...

AI Technical Summary

Problems solved by technology

But the wrapping material of prior art generally has following defect: 1, the sound insulation effect is poor, and present wrapping material hardly possesses sound insulation effect, and in order to reach sound insulation effect, common way is to thicken the thickness of each part of vehicle body, or carries out Complicated structural design to achieve sound insulation effect is suitable for high-end cars, but it is not practical for low-end cars, so in order to improve the sound insulation effect of low-end cars, It needs to be designed from the aspect of coating materials; 2. The fire performance is poor, and automobile spontaneous combustion accidents occur from time to time. It is well known that the important factors that cause harm to personnel during the spontaneous combustion of automobiles include the release of toxic fumes. How to effectively absorb the fumes is a The technical content that should be provided
