Problems solved by technology

[0002] Automotive interior processing generally uses ABS plastic, which is formed by a mold at one time. In order to enhance its fireproof performance, fireproof coating is usually sprayed on the interior surface. However, the fireproof performance of fireproof coating is limited, so it is necessary to strengthen ABS on the basis of fireproof coating. Fire resistance of plastics

Embodiment Construction

[0020] In the following, the present invention will be further described in conjunction with specific implementation methods. It should be noted that, on the premise of not conflicting, the various embodiments or technical features described below can be combined arbitrarily to form new embodiments.

[0021] The processing technology of large-scale interior parts for ABS flame-retardant buses includes the following steps:

[0022] In the sheet production step, the first sheet and the second sheet are coated with glue, and after adhering fire-resistant and flame-retardant cotton on the first sheet, the second sheet is covered to form a composite sheet; the sheet heating step will conform to The sheet is heated until softened; in the upper mold step, the softened composite sheet is placed above the mold and sealed with the mold by pressing; in the forming step, the air between the composite sheet and the mold is extracted to make the composite sheet Molding on a mold; cooling st...

Abstract

The invention provides a processing technology of large interior trim parts for an ABS flame-retardant bus, and relates to a processing technology of automotive trim. The processing technology of thelarge interior trim parts for the ABS flame-retardant bus is good in fireproof performance. The processing technology of the large interior trim parts for the ABS flame-retardant bus comprises a sheetmanufacturing step, a sheet heating step, a die loading step, a forming step and a cooling step. A double-layer interior trim part is formed on the basis of an original single-layer interior trim part, a middle interlayer is filled with the fireproof flame-retardant cotton to form a composite sheet, the fireproof performance of the interior trim part is improved by filling the fireproof flame-retardant cotton, and the fireproof performance of the double-layer interior trim part is better than that of the single-layer interior trim part sprayed with fireproof coating.

Description

technical field [0001] The invention relates to a processing technology for automobile interior decoration, in particular to a processing technology for bus interior decoration. Background technique [0002] Automotive interior processing generally uses ABS plastic, which is formed by a mold at one time. In order to enhance its fireproof performance, fireproof coating is usually sprayed on the interior surface. However, the fireproof performance of fireproof coating is limited, so it is necessary to strengthen ABS on the basis of fireproof coating. Fire resistance of plastics. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a processing technology for large interior parts of ABS flame-retardant buses with good fire performance. [0004] The present invention adopts following technical scheme to realize: the processing technology of ABS flame-retardant bus large-scale interior parts, comprises the following ...
