Description

A technological method for integrated and continuous winding of high-strength ultra-thin rubber strip-shaped sheet and long-fiber composite material

technical field

The present invention provides a technological method for integrated and continuous winding of a high-strength ultra-thin rubber strip-shaped sheet and a long-fiber composite material, which can be used to prepare a winding gyratory structure in which the rubber material and the fiber composite material are combined.

Background technique

The winding rotary structure combined with rubber material and long fiber composite material has been widely used in various industrial fields due to its advantages of light weight, high strength, high modulus, corrosion resistance and long life. High-performance rubbers such as nitrile rubber, butyl rubber and EPDM rubber are widely used as rotating inner wall materials due to their low density, good thermal insulation and weather resistance, and excellent processing performance. Combining the long fiber composite material as the winding outer layer can simultaneously exert the advantages of the long fiber reinforced composite material and the rubber material, and further expand the application field of the rubber material and the long fiber composite material. At present, a common method for preparing a gyratory structure combining a rubber material with a long-fiber composite material is to first use a traditional hand-patched rubber material, and then perform winding molding of the long-fiber composite material. According to the patent (CN 102632683 A), a manual patch manufacturing method of a filament wound rotary structure is proposed, which has disadvantages such as high labor intensity, unstable product size and quality, and the like.

Rubber and Plastic Technology and Equipment, 2018, 44(06): 14-18.) reported the use of unvulcanized raw tape-like sheets and The long-fiber composite material is wound by winding the rubber belt-like sheet and the dipped long fiber on the mandrel through the winding machine to prepare the winding revolving body structure. Due to defects such as overhead, the tape can not be wound around the head section, but only the straight section, which affects the performance of the entire process integration. In addition, since the rubber strip sheet is not vulcanized, bubbles will be generated in the subsequent vulcanization process, which will seriously affect the product performance. The patent (CN 101642961 A) firstly winds the rubber strip-shaped sheet layer onto the core mold through different tensions, and then pre-cures the rubber layer. Finally, the fibers are wound onto the tape layer for post-curing of the resin. This method can obtain a wound gyratory structure, but the segmented curing makes the preparation process cumbersome and the molding efficiency is low. , stress field, thermal field and other aspects of the matching, seriously affecting product performance. To sum up, the current molding process of rubber ribbon sheet and long fiber composite material has the following problems: the strength of rubber ribbon sheet is low, and it can only be used for winding straight barrel section, the molding method has low precision and efficiency, and the quality of molding products is unstable. and the immature post-curing process.

In order to solve the above problems, this patent proposes a technological method for the integrated and continuous winding of high-strength ultra-thin rubber strip-shaped sheet and long-fiber composite material, which provides a method for producing a winding gyratory structure combining rubber material and long-fiber composite material. an effective means.
