Abstract

The invention discloses carbon fiber surface treatment equipment comprising a trough frame, wherein the interior of the trough frame is divided into two independent spaces namely an electrolytic bath for containing electrolyte and a rinsing bath for containing deionized water; a cathode plate is arranged in the electrolytic bath and is connected with the negative electrode of an electrolysis power supply; a first insulating guide roll is arranged above the cathode plate in the electrolytic bath; a second insulating guide roll is arranged in the rinsing bath, and a third insulating guide roll is arranged above the trough frame between the first insulating guide roll in the electrolytic bath and the second insulating guide roll in the rinsing bath; anode guide rolls are respectively arranged above the trough frame on the outer side of the first insulating guide roll and the outer side of the second insulating guide roll, and are connected with the anode of the electrolysis power supply. By adopting the carbon fiber surface treatment equipment disclosed by the invention, the problem that the anode guide roll is oxidized and can not conduct electricity is solved, and meanwhile, by adopting the surface treatment method of the equipment disclosed by the invention, the surface treatment time can be shortened, so that the equipment and the surface treatment method can be applied to the fields of automobiles, medical treatment, food processing industry and chemical industry.

Description

technical field [0001] The invention relates to the technical field of carbon fiber surface modification, in particular to a carbon fiber surface treatment device, a surface treatment method and an application. Background technique [0002] Carbon fiber has excellent mechanical properties. Carbon fiber is widely used in the field of reinforced polymer materials. In order to improve the interfacial properties of carbon fiber and polymer composite materials, electrochemical methods are widely used in industry to treat the surface of carbon fiber. However, existing patents and technologies cannot Solve two problems in production: (1) The anode guide roller is easily oxidized. Chinese patent CN 10141848A discloses a carbon fiber surface treatment machine. The anode guide roller of the treatment machine is easily oxidized by the electrolyte, because the anode roller With current, when the carbon fiber runs at a certain speed, the electrolyte is introduced from the electrolytic ce...
