摘要

EVOH, PE and EVA films were prepared by extrusive blowing techniques, the optic capability, transmittance, haze, infrared anti-transmittance and heat preservation of the films were studied by IR spectroscopy and optic block. The result indicated that the haze degree of the EVOH film decreased about 10% and 5% compared to PE film and EVA film respectively, EVOH film's transmission of IR is much less than other films in the 2.5~25 μm wavelength range, it is just 9.03% in 7~14 μm wavelength range, and about 27% less than EVA film, while much less than PE film. It was found that EVOH film has much better capability of infrared anti-transmittance and point-blank light transmission than other two kinds of films. It was good for calefaction and heat preservation of greenhouse.
