Problems solved by technology

However, frequent replacement of the rubber requires more funds, the technique of pasting is not easy to master, and may damage the sponge under the rubber
In addition, due to the difference in rubber and pasting technology or glue problems, we cannot guarantee the consistent performance of the racket before and after replacing the rubber.
In this way, it will affect the athletes' competition and training

Embodiment 1

[0020] According to different surface viscosity requirements of rackets, the present invention uses polymer resin, pH regulator, humectant, surfactant and solvent as raw materials to prepare a liquid that is applied on the rubber surface of the table tennis racket to increase its viscosity and maintenance effect. The polymer resin is a water-soluble polymer, and polyvinylpyrrolidone, methacrylic acid-methacrylate copolymer polymers are selected, such as polyvinylpyrrolidone K-17, K-60, K-90, methyl Acrylic acid-butyl methacrylate, methacrylic acid-butyl acrylate, etc. make it form a film on the surface of the racket, and the content accounts for 30% of the total weight of the liquid. General polymer resins are not neutral, and need to be adjusted to neutral with a pH regulator, otherwise the surface of the rubber will be corroded, and the selected pH regulator is an inorganic or organic alkali regulator. Sodium hydroxide, calcium hydroxide, etc., and organic amine compounds, s...

Embodiment 2

[0024] Select polyvinylpyrrolidone K-17 as polymer resin, rosin as tackifying resin, triethanolamine as pH regulator, proline as humectant, Tween 61 (Tween61) as surfactant, and the rest as ethanol and water . The specific preparation method is: add the tackifying resin rosin into ethanol, stir well to dissolve it. Then add the polymer resin polyvinylpyrrolidone K-17, after completely dissolving, add the acidity regulator triethanolamine to adjust to neutrality. Add humectant propylene glycol and surfactant Tween 61, mix evenly, add appropriate amount of water, and stir evenly. The specific proportions are listed in Table 1 below:

Embodiment 3

[0028] Use methacrylic acid-butyl acrylate copolymer as polymer resin, hydrogenated rosin as tackifying resin, isopropanolamine as pH regulator, hydroxyethyl carbonamide as humectant, Tween 81 (Tween81) as surface active agent, and the rest are ethanol and water. Concrete preparation method is as embodiment 1. The specific ratio is shown in Table 2 below:

Abstract

The invention discloses a thickening and maintenance solution for the rubber sheet of a table tennis bat and the preparation method thereof and belongs to the field of thickening and maintaining the rubber sheet of the table tennis bat. The invention is characterized in that: the solution mainly contains high molecular resin, a regulator for PH value, a humectant, a surface active agent and menstruum; wherein, the high molecular resin is water-soluble polymer that can form a layer of protective film on the rubber sheet of the table tennis bat; the regulator for PH value is organic alkali regulator; the surface active agent adopts nonionic surfactant. The invention helps to raise the glutinosity of the rubber sheet and greatly prolong the service life of the rubber sheet under the pre-condition of not affecting the elasticity of bats.

Description

technical field [0001] The present invention relates to a kind of mixed liquid which plays the role of thickening and maintaining the rubber of table tennis racket and its preparation method. Background technique [0002] During the use of the reversed rubber of the table tennis racket (that is, the rubber surface of the table tennis racket), due to the aging of the rubber, its viscosity decreases continuously, and the ability of the rubber to "eat the ball" also decreases. weakened. In order to ensure the performance of the racket and the quality of the shot, the rubber needs to be replaced frequently. However, frequent replacement of the rubber requires more funds, the sticking technique is not easy to master, and the sponge under the rubber may be damaged. In addition, due to differences in rubber, pasting techniques or glue problems, the performance of the racket before and after replacing the rubber cannot be guaranteed to be consistent. Like this, can influence the ...
