摘 要:研究了氨基磺酸钠盐交联改性的羽毛球拍胶粘剂的物相组成、润湿性能和室温拉伸性能。结果表明,当氨基磺酸钠盐含量为1%时,胶粘剂的粘度为79mPa·s、吸水率为15.46%、固体含量为43.17%、贮存稳定性>0.5年;随着氨基磺酸钠盐含量的增加,胶粘剂的粘度不断增大,吸水率和固体含量逐渐减小,而贮存稳定性都保持在>0.5年的水平。随着氨基磺酸钠盐含量的增加,粘胶剂的接触角呈现逐渐增大的趋势;随着氨基磺酸钠盐含量增加,胶粘剂试样的抗拉强度逐渐增大,而断后伸长率先增加后减小,在氨基磺酸钠盐含量为5%时取得断后伸长率最大值。

Abstract:The phase composition, wettability and room temperature tensile properties of the adhesive cross-linked and modified by sodium sulfamate were studied. The results showed that when the content of sodium sulfamate was 1%, the viscosity of the adhesive was 79 MPa. S, the water absorption rate was 15.46%, the solid content was 43.17%, and the storage stability was more than 0.5 years; with the increase of the content of sodium sulfamate, the viscosity of the adhesive increased, the water absorption and solid content decreased gradually, and the storage stability remained at the level of > 0.5 years. With the increase of the content of sodium sulfamate, the contact angle of adhesive increases gradually; with the increase of sodium sulfamate content, the tensile strength of adhesive sample increases gradually, while the elongation after fracture first increases and then decreases. When the content of sodium sulfamate is 5%, the maximum elongation after fracture is obtained.

羽毛球运动近年来在国内得到了快速普及与高速发展,拒不完全统计,现阶段参加体育健身运动的人中每10个人就有人喜爱羽毛球,这使得近些年来羽毛球拍生产厂家得到了迅速发展,然而,高质量羽毛球拍仍然需要良好的基础原材料以及与之相适应的胶粘剂相匹配[1-2]。而传统的羽毛球拍胶粘剂存在干燥固化时间长以及粘度较低等问题,且在实际生产过程中还存在能耗大以及污染等问题[3-5]。在此基础上,文章尝试开发出具有粘度大、能耗低和污染小等特性的水性聚氨酯膠粘剂,以期为羽毛球拍用胶粘剂的开发与性能提供支撑。
