The effects of the basic resin,drip agent,antifogging agent,infrared absorption and blocking agent,antioxidant and light stabilizer on the properties of the film prepared with ethylene-vinyl acetate (EVA)copolymerano-hydrotalcite were studied. The optimal formulae for the EVAano-hydrotalcite drip antifogging film was determined,in which the EVA,nano-hydrotalcite,antioxidant 1010,antioxidant 168, light stabilizer,drip agent,antifogging agent was 100.00,2.00,0.10,0.05,0.30,1.60,0.30 phr,respectively. The temperature in the film at night was increased by 2.5℃,the duration of the drip reached 12.4 days and the light transmission was 92.0%.%研究了基体树脂、流滴剂、消雾剂、保温阻隔剂、抗氧剂、光稳定剂对乙烯-乙酸乙烯共聚物(EVA)棚膜性能的影响,确立了EVA/纳米水滑石流滴消雾棚膜配方:EVA为100.00 phr,保温阻隔剂纳米水滑石为2.00 phr,抗氧剂1010为0.10 phr,抗氧剂168为0.05 phr,光稳定剂为0.30 phr,流滴剂为1.60 phr,消雾剂为0.30 phr.该棚膜内夜间温度可提高2.5℃,流滴持续时间达12.4天,透光率为92.0%.
