Abstract

The invention discloses a coating method of a carbon fiber prepreg product. The coating method comprises the following steps: (1) selecting a carbon fiber prepreg product, and carrying out dust removal cleaning treatment; (2) carrying out sealing treatment on the carbon fiber prepreg product; (3) preheating the surface of a sealed carbon fiber prepreg product; (4) carrying out one time of a plurality of times of powder coating on the surface of the preheated carbon fiber prepreg product to form a powder coating layer; (5) carrying out curing treatment on the powder coating layer on the surfaceof the carbon fiber prepreg product; (6) carrying out decoration treatment on the cured carbon fiber prepreg product; and (7) carrying out quality inspection packaging on the decorated carbon fiber prepreg product to obtain a finished product. Correspondingly, the invention also provides the carbon fiber prepreg product prepared by the method. The method is simple, the process is controllable, nosolvent participates in the reaction, VOCs are not released, and no waste is generated.

Description

technical field

[0001] The invention relates to the technical field of fiber products, in particular to a carbon fiber prepreg product and a coating method thereof. Background technique

[0002] Carbon fiber refers to high-strength and high-modulus fibers with a carbon content of more than 90%. High temperature resistance ranks first among all chemical fibers. Carbon fiber is made of acrylic fiber and viscose fiber, which is oxidized and carbonized at high temperature. It is an excellent material for manufacturing high-tech equipment such as aerospace and aviation.

[0003] Carbon fiber prepreg products are generally prepreg compounded with liquid epoxy resin, and its curing temperature is 80-100 degrees, and it is relatively brittle in the thickness direction. In addition, the surface of carbon fiber is relatively inert and not easy to wet, so the carbon fiber pre-impregnated epoxy composite material has many pores, so the carbon fiber pre-impregnated epoxy composite mate...
