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 1100-1200 cm(-1). Compared with the wavelength of 9-11 microm, the absorbance band at 1360 cm(-1) had a little shift. Hence, the capability of heat preservation of hydrotalcite-added agriculture film would be studied in the future work.
通过红外光谱研究了不同种类的水滑石及其对农用薄膜光学性能、透光率、红外抗透过率和保温性能的影响。发现由于大连产水滑石的粒径大于日本产的，薄膜的雾度降低了约1.5%。与滑石粉相比，水滑石具有更好的红外抗透过性能。但是从水滑石的光谱来看，无论是大连产的还是日本产的，在1100 - 1200 cm(-1)区域都没有红外吸收。与9 - 11微米的波长相比，1360 cm(-1)处的吸收带略有偏移。因此，在未来的工作中将研究添加水滑石的农用薄膜的保温性能。
