Embodiment 1

[0043] (1) Preparation of dopamine functional monomer containing double bond

[0044] Dissolve 10 g of sodium borate decahydrate and 4 g of sodium bicarbonate in 100 mL of distilled water, and after degassing by nitrogen bubbling for 20 minutes, add 5 g of dopamine hydrochloride and stir well. 4.7 mL of methacrylic anhydride / THF (25 mL) solution was slowly added dropwise to the above mixed aqueous solution; the pH value of the aqueous solution was adjusted to ≥8 with NaOH, and the reaction mixture was stirred at room temperature for 14 h under nitrogen bubbling. The resulting white slurry solution was washed twice with 50 mL of ethyl acetate, filtered, and the resulting aqueous solution was acidified with 6 mol / L HCl to pH = 2; the organic layer in the solution was extracted with 50 mL of ethyl acetate for 3 times, concentrated by a rotary evaporator, Add dropwise to 250 mL of n-hexane for precipitation, filter, and vacuum-dry to obtain a brown solid product.

Abstract

The invention belongs to the technical field of polymer material modification and its application, and relates to a method for synthesizing a surface-modified functional gel of artificial turf fibers. The present invention prepares a gel containing dopamine functional groups that can be coated on general-purpose polyethylene artificial grass fibers, which improves the adhesion of the gel coating on PE grass fibers, and not only can achieve reversible moisture Absorption and release endow the surface of PE fiber with good self-cooling performance and surface antifouling and self-cleaning performance. After the performance test of the synthesized gel, it was found that it has superior softness, can be easily bent, twisted, etc., and can return to the original state in time after releasing the external force, which is helpful for improving the human body's sports comfort on the turf. Sensation and injury reduction are beneficial. The gel can absorb water and swell rapidly, and in this swollen state, it can maintain a large volume of water without dissolving. The test found that the gel has a high degree of water absorption, which can effectively reduce the temperature of the lawn.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification and its application, and relates to a method for synthesizing a surface-modified functional gel of artificial turf fibers. Background technique [0002] In recent years, artificial turf has developed vigorously. Based on its advantages of safety, environmental protection, convenient maintenance, and meeting the requirements of all-weather use, it is widely used in various leisure and sports venues such as football, tennis, and golf courses, or as ground paving to beautify the environment. However, with the in-depth research on artificial turf, it is found that compared with natural grass, artificial turf absorbs heat more easily under sunlight, making the surface temperature higher, and the temperature increases by about 30 to 40 degrees Celsius, which greatly increases The risk of heat stroke for event personnel affects the safety of the event. [0003] The extremely hydrop...
