Racket surface structure of pike racket and preparation method thereof

Abstract

According to the racket surface structure of a pike racket and a preparation method thereof, sizing treatment is conducted on carbon fibers through acetone, then oxidation treatment is conducted on the carbon fibers through a silver nitrate solution and a potassium peroxodisulfate solution, more oxygen-containing functional groups are formed on the surfaces of the carbon fibers, and therefore theinfiltration degree of the carbon fibers is enhanced; the melamine is grafted to the oxidized carbon fiber, so that the binding force between the carbon fiber and the epoxy resin is enhanced, the crack forming work, the expansion work and the impact work of the carbon fiber are further obviously increased, and corrosion resistance of the carbon fiber is improved; carbon fibers can be broken only by needing higher impact energy, and the mechanical properties of the carbon fibers are effectively improved, so impact resistance of the prepared racket surface structure of the pike racket is obviously improved, and the service life of the racket surface structure is obviously prolonged.

Description

technical field [0001] The invention relates to the field of sporting goods, in particular to a pickle racket surface structure and a preparation method thereof. Background technique [0002] Pickleball is a sport of hitting a ball with a racket, and it is also a hybrid sport that combines tennis, badminton and table tennis. [0003] The existing pickle racket head structure is made of wood or made of carbon fiber or glass fiber. The surface of the Pickleball racket made of wood is heavy, has poor hand feeling and hard hardness; when athletes are exercising, it has poor elasticity, bad hand feeling, poor durability and short service life. The surface of a pickle racquet made of carbon fiber or glass fiber has a complex structure, is difficult to manufacture, and takes a long time. Moreover, the existing carbon fiber or glass fiber is prone to single-filament breakage, resulting in a decrease in fiber strength. The quality of the surface of the obtained Pickle racket is uns...

Problems solved by technology

[0005] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a pickle racket surface structure and its preparation method: by adding carbon fiber into the Soxhlet extractor, then adding acetone, heating up to the acetone boiling, and then reflux Extract for 48-72 hours, reflux extraction is completed, filter after cooling, take out the filter cake and vacuum dry to obtain pretreated carbon fiber, mix equal volumes of 0.15mol / L silver nitrate solution and 0.15mol / L potassium persulfate solution Evenly, the first mixed solution is obtained, the pretreated carbon fiber is added to the first mixed solution, and the temperature is 65-75°C. After constant temperature reaction for 1-2h, filter, take out the filter cake and repeat with deionized water Wash 3-5 times, obtain product A after vacuum drying, mix thionyl chloride and N,N-dimethylformamide according to the volume ratio of 18-20:1 to obtain the second mixed solution, add product A into the second mixed solution, and react at a constant temperature for 36-50 hours at a temperature of 75-80°C, then filter, take out the filter cake and wash it repeatedly with deionized water for 3-5 times to obtain product B, and add melamine to In distilled water, then add a condensing agent and mix evenly to obtain the third mixed solution. Add the product B and the third mixed solution to the reaction kettle, and react for 30-40min at a temperature of 280-320°C and a pressure of 12MPa. After cooling, filter, take out the filter cake and wash it repeatedly with ethanol for 3-5 times, obtain modified carbon fiber after vacuum drying, weave the modified carbon fiber to form modified carbon fiber cloth, and use honeycomb aluminum material and modified carbon fiber cloth according to the peak The racket is cut and shaped according to the specifications of the racket, and then the cut modified carbon fiber cloth is glued to the upper and lower surfaces of the cut honeycomb aluminum material to obtain the surface structure of the Peak racket, which solves the problem of the surface and structure of the existing Peak racket made of carbon fiber. It is more complicated and difficult to manufacture, and the existing carbon fiber or glass fiber is prone to monofilament breakage, resulting in a decrease in fiber strength, making the surface quality of the prepared Pickle racket unstable, prone to yarn clamping, material shortage, internal fold or break problem
