Description

Technical Field

[0001] The present application relates to the technical field of badminton, and more specifically, to a badminton feather toughening agent, a preparation method thereof, and an application thereof. Background Art

[0002] As people's living standards continue to improve, they're placing a greater emphasis on physical fitness, and badminton has gradually become a popular sport. A badminton ball consists of a tee, feathers, and strings. The feathers are typically natural goose or duck feathers. Natural feathers are lightweight and rigid, providing an ideal feel and trajectory. However, natural feathers are primarily composed of keratin, which, after washing, bleaching, and drying, loses some of its oil content, making the processed feathers brittle and prone to cracking. These feathers are particularly susceptible to breaking when struck by a racket, significantly reducing the shuttlecock's lifespan. This wastes resources and hinders its widespread use.

[0003] Currently, badminton feathers are commonly treated with humidifiers or fumigators. Although the resulting badminton has a certain improvement in its durability, the improvement effect is not good. Therefore, there is an urgent need to propose a badminton feather toughening agent and its preparation method and application to solve the problem of poor durability of existing badminton and facilitate the further promotion of badminton. Summary of the Invention

[0004] In order to solve the problem of poor durability of existing badminton, the present application provides a badminton feather toughening agent and its preparation method and application.

[0005] In the first aspect, the present application provides a badminton feather toughening agent, which adopts the following technical solution:

[0006] A badminton feather toughening agent comprises the following raw materials in parts by weight: 30-40 parts of water, 4-6 parts of silk fibroin, 6-15 parts of betaine, 6-10 parts of a modifier, 4-6 parts of a silane coupling agent hydrolyzate, and 0.5-1.25 parts of a water-soluble silicone oil;

[0007] The modifier comprises the following raw materials in parts by weight: 20-40 parts of isopolyisocyanate, 1-3 parts of organotin, 10-20 parts of resveratrol, 30-50 parts of β-cyclodextrin / castor oil polymer, and 40-60 parts of ethyl acetate.

[0008] By adopting the above technical scheme, the raw materials of the badminton feather toughening agent of the present application include silk fibroin, betaine, a modifier, a silane coupling agent hydrolyzate, a water-soluble silicone oil and other raw materials, among which the silk fibroin can effectively improve the phenomenon that the feathers are easily brittle; the silane coupling agent hydrolyzate can strengthen the connection between the raw materials, so that the toughening agent forms a network of macromolecules on the surface of the feathers, increases the bonding relationship between the toughening agent and the feathers, and thereby improves the toughening effect of the feather toughening agent; betaine and water-soluble silicone oil can make the feathers soft, breathable, smooth, and antistatic; and the modifier of the present application is made of raw materials such as isopolyisocyanate, organic tin, resveratrol, β-cyclodextrin / castor oil polymer, etc. The modifier is beneficial to enhancing the toughness of the feathers and improving the mechanical properties of the feathers; using the toughening agent of the present application to treat the feathers of the badminton can make the feathers have excellent mechanical properties, thereby improving the durability of the badminton.

[0009] Preferably, the modifier is prepared by the following method:

[0010] Dissolve 3 / 5 of the total mass of isophorone diisocyanate, resveratrol, and organotin in ethyl acetate, stir and react at 40-50°C for 3-4 hours; add β-cyclodextrin / castor oil polymer and the remaining organotin, heat to 55-72°C, stir and react for 5-6 hours, stop the reaction, and remove impurities by rotary evaporation to obtain a modifier.

[0011] By adopting the above technical solution, the present application reacts isophorone diisocyanate and resveratrol. Under the catalytic action of organotin, the unsaturated bond -N=C=O of isophorone diisocyanate reacts with the hydroxyl group -OH in resveratrol, introducing a phenyl rigid group and improving the cohesion of the modifier; then, a β-cyclodextrin / castor oil polymer is added, and the hydroxyl group -OH of the β-cyclodextrin / castor oil polymer can further react with the remaining unsaturated bond -N=C=O in isophorone diisocyanate to increase the cross-linking density. At the same time, the hollow structure of β-cyclodextrin is introduced, making the spatial structure of the modifier richer, making the toughening effect of the toughening agent better, and effectively improving the tensile properties of the hair piece.

[0012] Preferably, the β-cyclodextrin / castor oil polymer comprises the following raw materials in parts by weight: 100 parts of castor oil, 10-20 parts of sorbic acid solution, 0.05-0.1 parts of polymerization inhibitor, 10-15 parts of β-cyclodextrin, 8-12 parts of pyridine, 40-60 parts of water, and 1-2 parts of p-toluenesulfonic acid.

[0013] Preferably, the sorbic acid solution is obtained by mixing sorbic acid and ethyl acetate in a mass ratio of 1:11-15.

[0014] Preferably, the β-cyclodextrin / castor oil polymer is prepared by the following method:

[0015] S1. Mix castor oil, sorbic acid solution, and polymerization inhibitor, and react at 140-180° C. for 1-2 hours to obtain carboxylated castor oil;

[0016] S2. Dissolve β-cyclodextrin in water, add pyridine, and mix thoroughly with carboxylated castor oil and p-toluenesulfonic acid. Heat to 120-160° C. under nitrogen protection to react for 2-3 hours to obtain a β-cyclodextrin / castor oil polymer.

[0017] By adopting the above technical solution, the present application first uses castor oil and sorbic acid to undergo a DA reaction to introduce carboxyl groups into the castor oil molecules; then, water-soluble β-cyclodextrin undergoes phase transfer via pyridine and undergoes an esterification reaction with the carboxylated castor oil, so that the β-cyclodextrin is successfully grafted onto the castor oil, resulting in a large number of hydroxyl groups on the surface of the β-cyclodextrin / castor oil polymer, which can further react with isophorone diisocyanate to increase the cross-linking density, thereby allowing interaction between isophorone diisocyanate, resveratrol, and the β-cyclodextrin / castor oil polymer, which is beneficial to improving the performance of the badminton feather toughening agent.

[0018] Preferably, the organotin is obtained by mixing dibutyltin dilaurate and dioctyltin oxide in a mass ratio of 3-7:4.

[0019] By adopting the above technical solution, the organotin of the present application is obtained by mixing dibutyltin dilaurate and dioctyltin oxide in a specific mass ratio. The interaction between the two can increase the reaction rate, reduce the occurrence of side reactions, and make the performance of the modifier more excellent.

[0020] Preferably, the betaine is obtained by mixing dodecyl dihydroxyethyl betaine and cocamidopropyl betaine in a mass ratio of 2-6:5.

[0021] By adopting the above technical solution, the betaine of the present application is obtained by mixing dodecyl dihydroxyethyl betaine and cocamidopropyl betaine in a specific mass ratio. The two synergistically enhance each other's performance, which can, on the one hand, play a role in toughening and strengthening, and on the other hand, can make the raw materials evenly dispersed, thereby improving the stability of the toughening agent.

[0022] Preferably, the silane coupling agent hydrolyzate is obtained by mixing KH550, KH792, water and ethanol in a mass ratio of 1:1-3:4-8:15-20.

[0023] By adopting the above technical solution, the silane coupling agent hydrolyzate of the present application uses two amino silane coupling agents with different structures, KH550 and KH792, as main raw materials. Under the joint action of water and ethanol, a hydrolysis reaction occurs, so that the silane coupling agent hydrolyzate contains a large number of active groups, which can be connected with other raw materials in the toughening agent to form a network of macromolecules, thereby improving the stability of the toughening agent and significantly improving the toughening effect of the treated hair piece.

[0024] In a second aspect, the present application provides a method for preparing a badminton feather toughening agent, which adopts the following technical solution: A method for preparing a badminton feather toughening agent comprises the following steps:

[0025] According to the formula, silk fibroin, betaine, a modifier, a silane coupling agent hydrolyzate and a water-soluble silicone oil are added into water and mixed evenly to obtain a badminton feather toughening agent.

[0026] By adopting the above technical solution, the preparation method of the badminton feather toughening agent of the present application has simple steps, low cost, is suitable for industrial production, and optimizes the comprehensive performance of the badminton feather toughening agent.

[0027] In a third aspect, the present application provides an application of a badminton feather toughening agent, which adopts the following technical solution:

[0028] An application of a badminton feather toughening agent for preparing badminton comprises the following steps:

[0029] Put the badminton on the conveyor belt, spray the badminton feather toughening agent evenly on the feathers of the badminton, and use it after it is naturally dried.

[0030] By adopting the above technical solution, the badminton feather toughening agent of the present application is used to treat the feathers of badminton. The application operation steps are simple, so that the badminton feather toughening agent can be evenly sprayed on the feathers of the badminton, which can effectively improve the mechanical properties of the badminton feathers, making the badminton durable and having broad market prospects.

[0031] In summary, this application has the following beneficial effects:

The serve frequency was controlled at 2 seconds per ball, the elevation angle was 35 degrees, and the height of the ball was 200 cm. Sixteen sets of badmintons were hit 100 times. The feathers of the badmintons were tested for damage, and the damage rate of each set was calculated. The damage rate was calculated as follows: Damage rate (%) = total number of badmintons with damaged feathers in each set / total number of badmintons in the initial set × 100%. The damage rate results are shown in Table 1.

Compared with Comparative Examples 3 and 4, the badminton feathers treated with the badminton feather toughening agent obtained in Example 1 have better overall performance.

[0144] From Example 1 and Comparative Example 5, it can be seen that: in Example 1, a modifier is added. Compared with Comparative Example 5, it can be seen that the badminton feathers treated with the badminton feather toughening agent obtained in Example 1 significantly improve the resistance to hitting of the badminton and are durable.

[0145] It can be seen from Example 1 and Comparative Examples 6 and 7 that the betaine in Example 1 is obtained by mixing dodecyl dihydroxyethyl betaine and cocamidopropyl betaine. Compared with Comparative Examples 6 and 7, the badminton feathers treated with the badminton feather toughening agent obtained in Example 1 have excellent tensile properties.

[0146] It can be seen from Example 1 and Comparative Examples 8 and 9 that the silane coupling agent hydrolyzate in Example 1 is obtained by mixing KH550, KH792, water and ethanol. Compared with the badminton treated with the badminton feather toughening agent obtained in Example 1, the badminton has better durability.

[0147] It can be seen from Example 1 and Comparative Example 10 that: in Example 1, a silane coupling agent hydrolyzate is added, and the badminton is treated with the badminton feather toughening agent obtained in Example 1, and the overall performance of the badminton is optimized.
