Embodiment Construction

[0018] The specific implementation of the present invention will be further described below in conjunction with examples. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0019] The technical scheme of the present invention is:

[0020] The present invention is a processing technology of woolen fiber car roof, the processing technology includes the following processing steps:

[0021] The first step: baking and heating the flax fiberboard;

[0022] The second step: molding the bast fiberboard after heating;

[0023] The third step: cutting the excess leftover material of the fluff fiberboard after molding.

[0024] In this implementation, the baking heating temperature in the first step can be controlled between 180°C and 260°C.

[0025] In this implementation, the optimal temperature for baking and heating in the first step is 220°C.

Abstract

The invention relates to a process for machining a composite substrate, in particular to a process for machining an environment-friendly type thermoplastic natural hair bastose automobile ceiling. The process comprises the following machining steps: 1, roasting and heating a hair bastose board; 2, carrying out mold compression and molding of the roasted and heated hair bastose board; and 3, cutting residual punched scrap of the hair bastose board after mold compression and molding. In the step one, the roasting and heating temperature is controlled to be between 180 and 260 DEG C; and the roasting and heating time is controlled to be between 140 and 180 seconds. The process for machining the composite substrate material for the environment-friendly type natural hair bastose automobile ceiling is easy to process and operate, and has low cost, no toxicity, regeneration, degradability, light weight, good hygroscopicity, noise absorbability, energy conservation, and environmental protection.

Description

Technical field [0001] The invention relates to a processing technology of a composite substrate. In particular, it relates to a processing technology of an environmentally-friendly thermoplastic natural woolen fiber car roof. It is mainly suitable for the processing of composite substrates of automobile roofs. It is also suitable for processing decorative building materials and packaging as substrates. It belongs to the technical field of composite sheet processing technology. Background technique [0002] With the rapid development of the automotive industry, the requirements for the quality and environmental protection indicators of automotive interior parts are getting higher and higher. The quality of interior parts depends critically on the composite substrate. The current composite substrate for automotive interior parts usually uses PU board (polyurethane board) or PP wood flour board. PU board is used to produce car roof. PP wood flour board is used in the production of ...
