摘　　要：使用红外光谱仪分别研究了进口水滑石、国产水滑石以及滑石粉对农膜光学性能、透光率、红外阻透率和保温性能的影响。结果表明国产水滑石粒径大于进口水滑石，制品雾度值上升1．5％左右。与常用的滑石粉相比，水滑石所制农膜的红外阻隔效果更好。从红外光谱图看出，国产或进口水滑石在1100~1200cm^-1波数范围内没有红外吸收，吸收峰值在1360cm^-1波数处，与吸收能量最强的9～11μm波长处有一定偏移，因此添加到农膜中作保温剂还有待于进一步研究。Different kinds of hydrotalcite and their effects on the optic capability, transmittance, infrared anti-transmittance and heat preservation of agriculture film were studied by IR spectroscopy. It was found that the haze degree of the film decreased about 1.5% because the diameter of the hydrotalcite made in Dalian was bigger than those made in Japan. Compared to the french chalk, the hydrotalcite had much better capability Of infrared anti-transmittance. But from the spectra of hydrotalcite, whichever made in Dalian or in Japan, there was no infrared absorption in the region of 1 100-1 200 cm^-1. Compared with the wavelength of 9-11μm, the absorbance band at 1 360 cm ^-1 had a little shift. Hence, the capability of heat preservation of hydrotalcite-added agriculture film would be studied in the future work.
