Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0031] A processing technology for a cover plate material of an automobile spare tire, comprising the following steps:

[0032] Step 1: Multi-layer extrusion lamination, extrude and laminate PP, GF composite surface layer, PP middle layer, PP, GF composite bottom layer from top to bottom to form a substrate; PP, GF composite surface layer and PP , GF composite bottom layer is made of PP, GF fully mixed and then extruded in the extruder, using a multi-die extruder, GF is to enhance the strength.

[0033] Step 2: moulding, laying the carpet surface on the mould, melting and laminating the PP and GF composite bottom layer of the substrate on the carpet surface by heating the mold, forming and punching to obtain the automobile spare tire cover plate material. The melting point of PP (poly...

Abstract

The invention relates to a processing technology of an automobile spare tire cover plate material, which comprises the following steps: multi-layer extrusion and lamination: extruding and laminating aPP/GF composite surface layer, a PP middle layer and a PP/GF composite bottom layer from top to bottom to form a substrate; and mold forming is conducted, specifically, the blanket surface is flatlylaid on a mold, the PP and GF composite bottom layer of the base plate is melted to cover the blanket surface through mold heating, forming and punching are conducted, and the automobile spare tire cover plate material is obtained. According to the scheme, PP in the PP and GF composite bottom layer can be melted at high temperature, the characteristic that the base plate can be secondarily processed is utilized, and glue is not used for bonding the fabric, so that the cost of the glue and the manufacturing cost of equipment required by spraying, pressing and other processes are saved; meanwhile, the problems of VOC emission and excessive odor caused by glue are also greatly reduced; only few technological processes are used, so that the production efficiency and the yield are greatly improved; the fabric and the base plate are trimmed at the same time, the end face and overflowing excessive glue cannot be seen, and the appearance is better.

Description

technical field [0001] The invention relates to the field of automobile spare tire cover material, in particular to a processing technology of the automobile spare tire cover material. Background technique [0002] Due to the continuous improvement of automobile energy-saving requirements and the continuous improvement of automobile overall emission requirements, traditional materials can no longer meet this requirement. The development and application of low-emission and high-load-bearing automobile spare tire board materials can well meet the performance proposed by customers. Unchanged, the requirements for lightweight parts and low emissions. [0003] Now the substrate production process can be roughly divided into: [0004] 1) The first step: forming the substrate, that is, the glass fiber layer + honeycomb paper core after spraying PU, and foaming in the mold. [0005] 2) The second step: Grinding the substrate to increase the surface roughness and improve the adhesi...
