磷酸二氢铵与硅烷偶联剂在纺织浆料中的应用与研究

Application and research of ammonium dihydrogen phosphate and silane coupling agent in textile size

利用INSTRON万能强力仪、傅里叶红外光谱仪、X射线衍射仪等仪器,探讨磷酸二氢铵加入由磷酸酯淀粉与丙烯酸酯组成的共混浆料的时机,研究磷酸二氢铵和硅烷偶联剂KH580处理的共混浆料,所形成浆膜的成分和结晶度,以及对织物的上浆率。研究结果表明:磷酸二氢铵在共混浆料糊化前加入,对共混浆料性能的提升效果更好。磷酸二氢铵会降低浆膜的结晶度,改善浆料的渗透性能,增加浆膜的强力。硅烷偶联剂对浆膜强力影响较小。两者共同作用时对浆膜性能有增强作用。改变硅烷偶联剂的加入量对上浆率的影响不明显,但增加磷酸二氢铵的加入量,织物上浆率增加。

Using INSTRON universal strength instrument,Fourier infrared spectrometer,X-ray diffractometer and other instruments,the timing of adding ammonium dihydrogen phosphate into the blended sizes which composed of starch phosphate and acrylic ester was investigated,and the composition and crystallinity of the sizing films formed from blended sizes treated with the ammonium dihydrogen phosphate and silane coupling agent KH580,and the sizing rates of fabrics,were studied.The experimental results showed that,adding the ammonium dihydrogen phosphate before gelatinization could improve the performance of the blended size better.The ammonium dihydrogen phosphate could reduce the crystallinity of the sizing film,improve the permeability of the sizing film,and increase the strength of the sizing film.The silane coupling agent had a little effect on the strength of the sizing film.And the combined action of the two could enhance the performance of the sizing film.Changing the amount of the silane coupling agent had no obvious effect on the sizing rate,but increasing the amount of the ammonium dihydrogen phosphate,the sizing rate increased.
