Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of plasma processing equipment, concretely relates to a reinforced fiber plasma continuous processing equipment. BACKGROUND

[0002] Reinforced fiber materials, especially aramid, ultra-high molecular weight polyethylene and carbon fiber, have attracted great attention of researchers due to their ultra-high mechanical strength, extremely low density, high chemical corrosion resistance, impact strength, high wear resistance and low moisture absorption, and are considered to have great development potential in lightweight high-strength composite materials, and have been widely used in medical, aerospace, construction, industry, fishery, ballistic protection and other fields. However, due to the lack of polar groups on the surface and the large chemical inertness, the surface adhesion of the reinforced fiber to the resin is low, which limits the full play of its excellent performance. Therefore, it is necessary to functionalize the fiber surface by introducing some polar groups to improve the interfacial adhesion.

[0003] As an efficient and energy-saving and environmentally friendly method, plasma modification method has been widely used. As the most common surface modification method, plasma modification is usually used to induce polar functional groups on the surface of reinforced fibers. When the equivalent gas ions bombard the surface of the fiber, their energy will be transferred from the plasma to the solid, which will change the surface morphology of the fiber, mainly increasing the roughness. Energy deposition will also lead to the generation of new active groups on the surface, such as hydroxyl, carbonyl, carboxyl and peroxide radicals, which will increase the adhesion between the polymer matrix material and the interface, improve the interfacial properties, and will not affect the overall properties of the material.

[0004] In order to obtain the diversity of treatment effect, the material surface modification treatment often adopts the vacuum plasma method, that is, under vacuum conditions, the gas is ionized to generate plasma, and the high-energy particles and active substances in the plasma react with the material surface to form new active groups on the material surface.

[0005] In the prior art, at present, the intermittent vacuum plasma equipment for treating block materials, roll materials and powder materials in the form of vacuum plasma has been successfully developed and put into use. In the aspect of continuous treatment of fiber materials by using vacuum plasma, Chinese patent CN202099616U (published on January 4, 2012) discloses a kind of thin film and fiber surface plasma continuous processing device, which comprises an plasma processing cavity, the plasma processing cavity is connected with a first vacuum container and a second vacuum container through a first connecting pipe and a second connecting pipe at both ends, the first vacuum container and the second vacuum container are controlled by a control system, the two vacuum containers are driven by a chain, the outer ends of the two vacuum containers are respectively provided with a first guide wheel and a second guide wheel, the first connecting pipe is provided with a first connector and a second connector; the second connecting pipe is provided with a third connector and a fourth connector.
