Embodiment Construction

[0048] In the current coating preparation method for the surface of the material, firstly, the surface of the substrate needs to be treated to remove grease and pollutants on the surface of the substrate, to improve the surface cleanliness and roughness of the material, and then to spray the primer on the surface of the substrate , and then scrape putty on the surface of the material that has been sprayed with primer, spray the middle paint, and finally spray the topcoat. Such a prepared coating structure is successively provided with a primer, a putty layer, an intermediate paint layer and a top coat layer on the surface of the substrate. However, such a coating preparation method has many steps, complicated process, long manufacturing cycle and high manufacturing cost. In addition, repeated high-temperature baking is required in the preparation process, which will reduce the performance of the matrix such as resin in the carbon fiber composite material, and then affect the p...

Abstract

The invention provides a preparation method of a carbon fiber composite material coating and a carbon fiber composite device. The method comprises the following steps: firstly, carrying out surface treatment on a carbon fiber composite material base material, and cleaning and polishing the surface layer of the carbon fiber composite material base material; secondly, scraping putty, and scraping the putty on the surface layer of the carbon fiber composite material base material subjected to surface treatment to form a putty layer; and thirdly, spraying intermediate coat, and spraying the intermediate coat on the surface layer of the putty layer to form an intermediate coat layer; and finally, spraying finish coat, and spraying the finish coat on the surface layer of the intermediate coat layer to form a finish coat layer. The carbon fiber composite device provided by the invention comprises the carbon fiber composite material base material and the carbon fiber composite material coating, wherein the carbon fiber composite material coating is prepared by the method. According to the preparation method and the carbon fiber composite device, the process manufacturing flow of the preparation of the carbon fiber composite material coating is optimized, the processing period is shortened, and the processing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of composite material preparation, in particular to a method for preparing a carbon fiber composite material coating and a carbon fiber composite device. Background technique [0002] The coating structure is to attach a protective layer on the surface of the material, which is used to block external corrosion particles, avoid contact with the surface of the material, prevent chemical reactions from affecting the performance of the material, and improve the aesthetics of the surface of the material. [0003] At this stage, when coating materials, the surface of the substrate is firstly treated to remove all pollutants on the surface of the substrate; then the surface of the substrate is sprayed with primer; and then, the surface of the material that has been sprayed with primer is sequentially Carry out two coats of putty scraping and two coats of putty, and finally carry out topcoat spraying. The surface c...
