Embodiment Construction

[0043] Next, the technical solutions in the embodiments of the present invention will be apparent from the embodiment of the present invention, and it is clearly described, and it is understood that the described embodiments are merely embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.

[0044] Such as figure 1 As shown, a composite molded coating process is characterized in that the following steps are included.

[0045] Step 100. After the mold is prepared, the release agent is sprayed into the surface of the mold through the peripheral device;

[0046] Step 200, after mixing the coating and the curing agent, spray the surface of the mold through the peripheral device according to the predetermined track, and form a solidified lattice layer on the surface of the mold by controlling the curing condition;

Abstract

The invention discloses a composite material in-mold coating process. The composite material in-mold coating process comprises the following steps that step 100, after a mold is pretreated, a release agent is evenly sprayed to the surface of the mold through an external device; step 200, a coating and a curing agent are mixed according to a proportion, the coating and the curing agent are sprayed on the surface of the mold through the external device according to a preset track, and a cured gel coat layer is formed on the surface of the mold by controlling curing conditions; step 300, a prefabricated part which is made of the same material as the coating is put into a mold, and compression molding is carried out by controlling molding conditions; and step 400, demolding is carried out, and a formed workpiece is taken out and is subjected to post-treatment. The composite material in-mold coating process is adopted, the gel coat is evenly sprayed on the surface of the mold, after the coating is cured, raw materials are put into the mold to be cured and formed, then a product can be taken out to obtain a colored product, the surface of the workpiece is covered with the gel coat coating while the workpiece is formed, the formed workpiece covered with the gel coat layer is obtained at a time, the original paint spraying procedure is simplified, and the pressing difficulty is reduced.

Description

Technical field [0001] The present invention relates to the field of composite surface treatment techniques, and more particularly to a composite molded coating process. Background technique [0002] Composites are widely used in various fields due to their high materials, high impact strength, high temperature difference, anti-aging, anti-corrosion, lightning, static electricity and high compatibility with various materials. In the surface of the composite lacquer, the color unevenness of the surface of the article can eliminate the disadvantage of the surface of the article, supplemented with insufficient molding and adjustment of surface gloss. [0003] At present, the existing composite product spraying method is similar to the painting of metal products. The first is cleaning, handling the surface of the article, the surface of the article, ensures the finish, and then uses a dedicated putty according to the surface conditions, followed by spraying. However, this spray metho...
