Problems solved by technology

[0005] 1) It is difficult to cut the sheet into raw materials that meet the size requirements. Since the cross-sectional shape of the badminton racket is approximately circular, the high-energy adhesive is cut into square strips, and there will be dimensional deviations after rolling the product, resulting in defective products;
[0006] 2) The high-energy adhesive of the cut sheet cannot be well bonded to the fiber composite material during the rolling process, and there are gaps, which are difficult to exclude in the later heating and forming process, so that products with poor appearance are more likely to appear
[0007] 3) Since the middle tube of badminton racket is thinner and requires higher structural precision, sheet high-energy adhesive is especially not suitable for forming the middle tube of badminton racket

Abstract

The invention relates to linear high-energy plastic and a preparation method thereof. The linear high-energy plastic is prepared by immersing a linear supporting material into a heat-expandable composite resin material, wherein the heat-expandable composite resin material accounts for 10-70% of the total weight of the moulded linear high-energy plastic; the heat-expandable composite resin material comprises a hot-melt heat-expandable composite resin material and a solvent-based heat-expandable composite resin material. The linear high-energy plastic is applicable to moulding of a badminton racket, especially moulding of a middle tube of the badminton racket, the obtained badminton racket is plump in appearance and free of air bubbles therein, and the flexibility and the torque of the racket are taken into account; the preparation method is simple, low in cost and convenient in industrial application.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to a linear high-energy glue and a preparation method thereof. Background technique [0002] During the molding process of badminton rackets, the requirements for the middle tube are relatively high, and the performance of the badminton racket depends to a large extent on the middle tube. The diameter of the middle tube of a badminton racket is generally about 7mm. The thicker the middle tube, the stronger the torque, but the poor flexibility; the thinner the middle tube, the better the flexibility, but the worse the torque. [0003] In order to maximize the player's batting skills, it is the current research direction to make the middle tube of badminton racket through the design of thinner tube diameter and composite material with high elastic modulus. [0004] Patent application CN103146216A discloses a high-energy adhesive product, which coats the composite material on the suppo...
