Description

A method of making a lightweight luminous tennis ball

technical field

The invention relates to sports equipment, in particular to a method for making a lightweight luminous tennis ball.

Background technique

Tennis is a ball game, usually played between two singles players or a combination of two pairs. A player hits a tennis ball with a tennis racket across the net on a tennis court. The tennis ball in the prior art is an inflatable hollow sphere structure, which requires sufficient gas to have good elasticity. However, the tennis ball in the prior art is directly made of rubber into a sphere, and then a decorative and protective woolen outer layer is arranged outside the sphere. In order to withstand a large air pressure, a sufficient thickness is required, thereby increasing the weight of the tennis ball and reducing the motion sensitivity. In addition, the tennis ball in the prior art is not suitable for occasions with weak light, which is not conducive to popularization. Therefore, there are improvements. space.

After the first layer is dry, the second layer is sprayed, and sprayed layer by layer until the reinforcing mesh layer is covered, and the surface is smooth. Can.

Further, the elastic rubber used in the inner tank is made by mixing natural rubber and acrylic resin.

Preferably, the ratio of the natural rubber to the acrylic resin is 7:1.

Preferably, the reinforcing mesh layer is a reinforcing mesh layer woven by carbon fiber material.

Further, the luminous material layer is composed of transparent natural rubber, rare earth, zirconia, acrylic resin, alumina ultrafine powder and polyurethane.

Preferably, by weight, each part contains 65% of the transparent natural rubber, 15% of the rare earth, 2% of the zirconia, 5% of the acrylic resin, 5% of the ultrafine alumina powder, and the polyurethane 8%.

Preferably, the outer protective layer is made of fleece material.

Preferably, the thickness of the inner pot is 1 mm; the thickness of the reinforcing mesh layer is 0.5 mm; the thickness of the luminous material layer is 1.2 mm, and the thickness of the outer protective layer is 2 mm.

The beneficial effects of the present invention are:

The present invention is a method for making a lightweight luminous tennis ball. Compared with the prior art, the present invention adopts a thinner inner bladder, and then a reinforcing mesh layer and a luminous material layer are arranged outside the inner bladder. The inner liner can withstand higher pressure, thereby reducing the thickness and weight, and the luminous material layer can emit light in a dark environment after the material is irradiated with strong light, which is beneficial to use in weak light situations, and the present invention is scientific The matched luminous material layer material can not only emit light, but also has wear resistance, improves the service life, and has the value of popularization and application.
