Production method of highlight D post decorative sheet

Abstract

The invention discloses a production method of a highlight D post decorative sheet. The D post decorative sheet is made by a highlight traceless shooting technique; according to the production method of the highlight D post decorative sheet, the highlight effect can be realized without the spraying on a highlight part after the D post decorative sheet is made by the highlight traceless shooting technique; under the precondition of effect guarantee, the cost can be reduced effectively, the delivery time can be shortened, and the environment pollution can be reduced.

Description

technical field [0001] The invention relates to an automobile exterior trim, in particular to a method for manufacturing a high-gloss D-pillar decorative panel. Background technique [0002] In recent years, as young people have gradually become the main force of car purchases, car design styles have gradually changed. OEM designers have introduced some innovative elements to win the favor of young people, such as using high-gloss D-pillar decorative panels to replace the rear door glass. It is consistent with the side door glass, which can bring a good visual transition. As appearance has become the first choice for more and more users to buy cars, the high-gloss design of exterior decoration has become a trend and is favored by more styling designers. Naturally, high-gloss parts have gradually become a selling point. The related manufacturing process, Structural design and material technology have naturally become the new focus of attention in the field of automotive engi...

Problems solved by technology

If the surface is to achieve a high-gloss effect, the varnish layer needs a thicker film thickness; but if the varnish layer is too thick, the parts will sag on the edge of the parts during the drying process after painting. To avoid sagging, it is necessary to Reduce the film thickness of the varnish layer, which does not meet the high standard requirements of high gloss

[0004] At the same time, in the process of painting, the volatilization of paint will cause certain harm to the environment.

During the spraying process of plastic parts, due to the non-recyclable thermosetting paint, there is a coating that cannot be easily peeled off, which eventually leads to difficulties in the recycling of the parts, which in turn creates obstacles for the recycling of automotive plastic parts

Moreover, due to the complexity of the painting process, it is necessary to increase the basic links such as pretreatment, coating, and transportation. Part of the painting process also requires multiple production processes such as primers, topcoats, and UV curing paints, as well as the resulting pass rate problems, making the entire Double or even triple the cost of parts
