|
摘要
为提高钢筘胶粘剂韧性及粘接强度,采用高分子改性增韧剂G构成复合增韧体系,之后对不同类型的固化剂进行优选,并添加纳米粒子SiO_2调节体系稳定性。通过傅里叶红外光谱仪和旋转流变仪等对钢筘胶粘剂的性能进行了研究。结果表明,制备的高速无梭织机钢筘用胶粘剂综合性能提高,冲击强度为9.86 kJ/m~2,拉伸剪切强度为21.77 MPa,无急剧放热现象,且黏度对温度的敏感性降低,施工工艺稳定。
In order to improve the toughness and bonding strength of reed adhesive, polymer modified toughening agent G was firstly applied to constitute the composite toughening system. Then, different types of curing agents were optimized, and nano-silica was added to regulate the system stability. The properties of reed adhesive were investigated by infrared spectrometer and rotational rheometer, etc. The results showed that the comprehensive properties of prepared reed adhesive for high-speed shuttleless loom were enhanced. The impact strength was 9.86 kJ/m~2 and tensile shear strength was 21.77 MPa. There is no rapid exothermic phenomenon, the sensitivity of viscosity to temperature declined, and the construction process was stable.
