Description

Technical Field

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

[0002] Badminton, a small-ball sport, is the nation's top sport, attracting a large number of participants, combining fitness, entertainment, and leisure. With the development of national fitness, badminton venues, parks, and outdoor badminton courts are now ubiquitous, providing a wide range of spaces and time options for people to practice badminton, ensuring that whenever they want to exercise, they only need to grab their badminton equipment.

[0003] Badminton balls used for fitness and competitions are typically made from biomass feathers like geese and ducks, offering superior flight performance compared to plastic shuttlecocks. Feathers are primarily composed of keratin, which is brittle and cracks easily when dried. Therefore, humidity significantly impacts the durability of biomass feather shuttlecocks. In dry weather, especially in northern winter indoors, feathers are particularly brittle and can easily break under the impact of rackets during use, shortening the shuttlecock's lifespan.

[0004] Currently, fumigation (fumigation with tap water) is commonly used to treat badminton. Although the treated badminton has a certain improvement in durability, it has disadvantages such as inconvenient portability of the fumigation equipment, difficulty in controlling the degree of fumigation, and long treatment time. Based on the above, the present application provides a badminton feather treatment agent, a preparation method, and applications thereof. Summary of the Invention

[0005] In order to solve the current problems of badminton's poor durability, inconvenient fumigation operation, and poor effect, the present application provides a badminton feather treatment agent, a preparation method, and an application thereof.

[0006] In the first aspect, the present application provides a badminton feather treatment agent, which adopts the following technical solution:

[0007] A badminton feather treatment agent comprises the following raw materials in parts by weight: 30-50 parts of deionized water, 8-12 parts of chitosan quaternary ammonium salt, and 0.1-1 part of water-soluble silicone oil.

[0008] Preferably, the badminton feather treatment agent comprises the following raw materials in parts by weight: 40 parts of deionized water, 10 parts of chitosan quaternary ammonium salt, and 0.5 parts of water-soluble silicone oil.

[0009] By adopting the above technical solution, chitosan quaternary ammonium salt has good antibacterial properties, film-forming properties, moisture absorption and moisturizing properties, antistatic properties and the like. When used for badminton feather treatment, it can significantly improve the antibacterial properties, toughness, folding resistance and the like of the badminton, thereby improving the badminton's durability. The addition of water-soluble silicone oil can form a cross-linked network with the chitosan quaternary ammonium salt through electrostatic action, thereby forming a protective film on the feather surface, further improving the badminton's durability and durability. The application has a scientific formula and a rigorous ratio. The resulting badminton feather treatment agent can play a role in long-term protection of the badminton. The operation for badminton treatment is simple, and the treated badminton significantly improves its durability and extends its service life.

[0010] Preferably, the chitosan quaternary ammonium salt is prepared by the following method:

[0011] (1) adding chitosan and anionic polyacrylamide to an acetic acid solution, stirring and mixing to obtain a mixed solution;

[0012] (2) adding 3-chloro-2-hydroxypropyltrimethylammonium chloride to the mixed solution of step (1), stirring and mixing, heating to 80-90° C., and stirring at this temperature for 1-2 hours to obtain a reaction mixture;

[0013] (3) adding the reaction mixture of step (2) to anhydrous ethanol, stirring and mixing, allowing to settle, and collecting the precipitate by centrifugation; (4) adding the precipitate of step (3) to deionized water, stirring and mixing, adding ferulic acid, ultrasonically treating, and spray drying to obtain the desired chitosan quaternary ammonium salt.

[0014] Preferably, in step (1), the mass ratio of chitosan, anionic polyacrylamide and acetic acid solution is 2.2-2.8:1:15.

[0015] Preferably, in step (2), the mass ratio of 3-chloro-2-hydroxypropyltrimethylammonium chloride to the mixed solution is 1.6-2:10.

[0016] Preferably, in step (3), the mass ratio of the precipitate, deionized water and ferulic acid is 3-3.5:10:1.

[0017] By adopting the above technical solution, the present application prepares chitosan quaternary ammonium salt using chitosan and 3-chloro-2-hydroxypropyltrimethylammonium chloride as raw materials. By adding anionic polyacrylamide and ferulic acid, the antibacterial properties, film-forming properties, moisture absorption and moisture retention of the chitosan quaternary ammonium salt can be further improved. When used for feather treatment, the chitosan quaternary ammonium salt can penetrate into the feathers, inhibiting the growth of bacteria and fungi, while significantly improving the softness and elasticity of the feathers themselves, further enhancing their resistance to breakage.

[0018] Preferably, the water-soluble silicone oil is a small molecule hydroxy silicone oil with a molecular weight of 300-1000.

[0019] By adopting the above technical solution, the elastic film formed by small molecule hydroxy silicone oil and chitosan quaternary ammonium salt can further improve the elasticity, deformation recovery and breakage resistance of the feathers. After film formation, the surface is dry and non-sticky, and will not affect the flight trajectory of the badminton.

[0020] Preferably, the badminton feather treatment agent raw material further includes 1-1.4 parts by weight of a cross-linking agent.

[0021] Preferably, the cross-linking agent comprises sodium sulfate and ethylene glycol dimethacrylate in a mass ratio of 3-5:1.

[0022] By adopting the above technical solution, a combination of sodium sulfate and ethylene glycol dimethacrylate is selected as a crosslinking agent. On the one hand, the crosslinking agent can crosslink the keratin in the feathers to form a stronger structure, thereby enhancing their toughness and strength. On the other hand, the crosslinking agent can further crosslink the chitosan quaternary ammonium salt and water-soluble silicone oil to form a protective film on the feather surface, making the feathers more tough and further improving the durability and elasticity of the feathers.

[0023] In a second aspect, the present application provides a method for preparing a badminton feather treatment agent, which adopts the following technical solution: A method for preparing a badminton feather treatment agent, comprising the following preparation steps:

[0026] Chitosan quaternary ammonium salt and water-soluble silicone oil are added to deionized water in parts by weight, stirred and mixed evenly, and then a cross-linking agent is added and continued to be mixed evenly to obtain the desired badminton feather treatment agent.

[0027] By adopting the above technical solution, the preparation method of the badminton feather treatment agent proposed in this application is simple to operate, has mild preparation conditions, and is suitable for industrial production.

[0028] In a third aspect, the present application provides an application of a badminton feather treatment agent, which adopts the following technical solution:

[0029] The invention discloses an application of a badminton feather treatment agent. The badminton feather treatment agent is prepared according to a preparation method of the badminton feather treatment agent, and then evenly sprayed onto the surface of feathers and dried to form a film.

[0156] Application Example 1

[0157] 160 badminton shuttlecocks (Asian Lion RSL No. 10) were divided into 16 groups, and treated with the badminton feather treatment agents prepared in Examples 1-10 and Comparative Examples 1-5 of the present application, respectively. Examples 1-10 and Comparative Examples 1-5 are described, specifically:

[0158] Evenly spray the badminton feather treatment agent on the feathers of natural badminton, control the spraying amount to 3ml / battled, and use it after it dries naturally to form a film.

[0159] The other 10 rats were not treated with badminton feather treatment agent and were recorded as the blank group.

[0160] Application Example 2

[0161] 1600 badminton shuttlecocks (Asian Lion RSL No. 10) were divided into 16 groups, and treated with the badminton feather treatment agents prepared in Examples 1-10 and Comparative Examples 1-5 of the present application, respectively. Examples 1-10 and Comparative Examples 1-5 are recorded, specifically:

[0162] Evenly spray the badminton feather treatment agent on the feathers of natural badmintons, controlling the spraying amount to 3ml / bird. After it dries naturally to form a film, store it for 30 days before use.

[0163] Another 100 badminton feathers were not treated with the badminton feather treatment agent and were recorded as the blank group.

[0164] Performance Testing

[0165] Badminton durability: In a closed room at a temperature of 20±2°C and a humidity of ≥95%, an intelligent automatic badminton serving machine was used. The frequency of the serve was controlled at 2 seconds per ball, the elevation angle was 35 degrees, and the height of the serve was 200 cm. The shuttlecock was hit until the feathers broke. The total number of hits was counted and the shuttlecock was discarded.

[0166] Based on the average service life of the badminton in the blank group, the average service life improvement of the badmintons in Examples 1-10 and Comparative Examples 1-5 was calculated [Average service life improvement = (average number of hits of the badminton in the test group - average number of hits of the badminton in the blank group) ÷ average number of hits of the badminton in the blank group × 100%]. The resulting badminton durability test data is shown in Table 1.

[0167] Table 1:

[0168] Test samples Improvement in service life immediately after drying / % Improvement in service life after 30 days of storage / % Example 1 21.7 19.4 Example 2 24.3 23.0 Example 3 23.5 21.7 Example 4 29.2 27.5 Example 5 31.6 29.6 Example 6 31.3 30.2 Example 7 33.5 31.8 Example 8 29.8 29.5 Example 9 35.2 33.3 Example 10 32.7 30.5 Comparative Example 1 15.4 9.7 Comparative Example 2 19.7 14.8 Comparative Example 3 13.2 10.3 Comparative Example 4 26.7 17.1 Comparative Example 5 25.8 15.5

[0169] As shown in Table 1, the badminton feather treatment agents prepared in Examples 1-10 of the present application significantly improve the durability of the badminton, and the improvement effect is far superior to the treatment effect of the badminton feather treatment agents prepared in Comparative Examples 1-5. This shows that under the preferred raw material ratios and process parameters of the present application, the raw materials in the formula can interact with each other and synergize to enhance the effect, thereby significantly improving the durability of the badminton and extending its service life.

[0170] By comparing Example 1 with Comparative Examples 1-3, it can be seen that the chitosan quaternary ammonium salt prepared in the present application has a more significant treatment effect than the commercially available chitosan quaternary ammonium salt, can significantly improve the durability of the badminton and extend its service life; in the preparation process of the chitosan quaternary ammonium salt in the present application, the addition of anionic polyacrylamide and ferulic acid can further improve the antibacterial property, film-forming property, moisture absorption and moisture retention of the chitosan quaternary ammonium salt. When used for feather treatment, it can penetrate into the feathers and inhibit the growth of bacteria and fungi. At the same time, it significantly improves the softness and elasticity of the feathers themselves, further enhancing their breakage resistance and durability.

[0171] By comparing Example 1 with Comparative Examples 4-5, it can be seen that the combination of sodium sulfate and ethylene glycol dimethacrylate as a cross-linking agent has a more significant treatment effect than the use of sodium sulfate or ethylene glycol dimethacrylate alone as a cross-linking agent, which can significantly improve the durability of the badminton and extend its service life.

[0172] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
