Problems solved by technology

[0005] In order to overcome the problems of the high concentration of volatile organic compounds (VOC) in the air in the car existing in the prior art, the present invention provides a novel TPO-skin environment-friendly automotive soft instrument panel and its manufacturing method. In terms of material selection , using low-VOC and low-odor TPO as the instrument panel skin, low-VOC and low-odor PET 3Dmesh as the instrument panel buffer material, glass fiber reinforced PP material as the instrument panel skeleton
The VOC volatility of the final product has been significantly reduced, which solves the shortcomings of traditional slush-plastic PVC skin and PUR foam buffer layer, and meets the environmental protection and high-quality requirements of OEMs for interior parts

Embodiment 1

[0028] Such as figure 1 As shown, a new TPO-skin environment-friendly automotive soft instrument panel, from the inside to the outside is a skeleton layer, a middle buffer layer and a skin layer; the skeleton layer is a glass fiber reinforced PP material, and the middle buffer layer is a three-dimensional net PET 3D mesh material with porous structure, the skin layer is TPO material with base cloth.

[0029] The instrument panel skin material: TPO skin with low VOC volatilization and low odor of water-based polyurethane surface coating.

[0030] The middle buffer layer material of the instrument panel: PET 3D mesh material with three-dimensional mesh structure, thickness 3mm, surface density 240-300g / m 2 .

[0031] The material of the skeleton layer of the instrument panel: 30% glass fiber reinforced PP material.

[0032] The glue used in the process: environmentally friendly polyurethane water-based glue.

Embodiment 2

[0034] Such as figure 2 Shown, a kind of manufacturing process of new-style TPO skin environment-friendly automobile soft instrument panel, concrete steps are as follows:

[0035] 1) Dashboard skin layer: After cutting the TPO skin according to the required size of the dashboard and sewing it into a specified shape, spray environmentally friendly polyurethane water-based glue on the back base fabric, and the amount of glue sprayed is 40-80g; then put the TPO skin in the heating room Drying, heating temperature 60-80 ℃, heating time 15-30min;

[0036] 2) Dashboard buffer layer: PET 3D mesh material is cut into a specified shape, and the A side is sprayed with environmentally friendly polyurethane water-based glue, with a spray amount of 40-80g; then it is placed in a heating room for drying at a heating temperature of 60-80°C. Heating time 15-30min;

[0037] 3) Dashboard frame: Injection molding of glass fiber reinforced PP material, spray environmentally friendly polyuretha...

Abstract

The invention provides a novel TPO skin environment-friendly automobile soft instrument board and a manufacturing method thereof, and belongs to the technical field of instrument boards for automobileinteriors, the novel TPO skin environment-friendly automobile soft instrument board sequentially comprises a skeleton layer, a middle buffer layer and a skin layer from inside to outside, wherein theskeleton layer is made of a glass fiber reinforced PP material, the middle buffer layer is made of a PET 3D mesh material with a three-dimensional mesh structure, and the surface layer is made of a TPO material with base cloth. In the aspect of material selection, TPO with low VOC volatilization and low odor is used as an instrument board skin, PET 3Dmesh with low VOC volatilization and low odoris used as an instrument board buffer layer material, and a glass fiber reinforced PP material is used as an instrument board framework. In the aspect of the manufacturing process, the environment-friendly soft instrument board is finally manufactured through design and implementation of a novel environment-friendly process. The VOC volatility of the final product is obviously reduced, the defectthat the smell of a traditional slush molding PVC surface layer and a PUR foam buffer layer is poor is overcome, and the environment-friendly and high-quality requirements of a main engine plant for interior trim parts are met.

Description

technical field [0001] The invention belongs to the technical field of instrument panels for automobile interior decoration, and in particular relates to a novel TPO-skin environment-friendly automobile soft instrument panel and a manufacturing process thereof. Background technique [0002] As automobiles are more and more integrated into the social life circle of the masses, and Chinese people pay more and more attention to their own health and environmental protection, major automobile OEMs at home and abroad are actively developing technological application innovations, and through The implementation of technology and the strengthening of production process management to improve the air quality in the car, on the one hand, aim to reduce the concentration of volatile organic compounds (VOC) in the air in the car that can be objectively characterized; Odor is the target, because it is easy to cause discomfort perception of drivers and passengers. [0003] At present, autom...
