Production system for preparing thermoplastic prepreg through mud method

Abstract

The invention discloses a production system for preparing thermoplastic prepreg through a mud method. The system comprises a sizing agent removal device, a gum dipping tank, a drying device, pultrusion mold and a winding device which are arranged in the fiber advancing direction. The gum dipping tank is connected with a slurry concentration adjusting device, the slurry concentration adjusting device comprises a buffer bucket, a high-concentration slurry storage tank, a slurry dispersion bucket and a raw material tank, a slurry outlet of the buffer bucket is connected with a slurry inlet of thegum dipping tank, a backflow pipe for conveying slurry in the gum dipping tank to the buffer bucket in a backflow manner is arranged between the buffer bucket and the gum dipping tank, the buffer bucket is connected with a sample detection pond through a slurry sample conveying pipeline, a viscometer is arranged in the sample detection pond, the high-concentration slurry storage tank is connectedwith the buffer bucket, the slurry dispersion bucket is connected with the buffer bucket and the high-concentration slurry storage tank, and is used for injecting slurry of the corresponding concentrations into the buffer bucket and the high-concentration slurry storage tank, and the raw material tank is connected with the slurry dispersion bucket. According to the production system for preparingthermoplastic prepreg through the mud method, the slurry concentration can be adjusted.

Description

technical field [0001] The invention relates to a prepreg production system, in particular to a production system for preparing thermoplastic prepreg by a slurry method. Background technique [0002] Resin-based composite materials, also known as fiber-reinforced plastics, are composite materials that use organic polymers as the matrix and glass fibers, carbon fibers, basalt fibers or aramid fibers as reinforcements. They have been widely used in various fields such as life and production. . At present, the preparation of thermoplastic prepreg is difficult and the cost is relatively high. Domestic and foreign research institutes and enterprises have successively developed a variety of thermoplastic prepreg preparation processes, such as powder method, film method, fiber hybrid method, solution method, melt extrusion method, original Polymerization, etc. [0003] At present, the large-scale production of thermoplastic carbon fiber prepreg in my country is in its infancy, th...

Problems solved by technology

In the prior art, the mold cavity of the pultrusion mold is of equal cross-section, the resin impregnation effect of this kind of mold is poor, and the resin is easy to accumulate at the mold entrance, which affects the entry of fibers into the mold, resulting in damage and fracture
