摘　　要：以丙烯酸（AA）、甲基丙烯酸甲酯（MMA）、γ-甲基丙烯酰氧丙基三甲氧基硅烷（KH-570）分别作为接枝单体,对EVA（乙烯-醋酸乙烯酯共聚物）进行接枝改性,着重探讨了接枝单体对EVA封装胶膜交联性能、粘接性能、透光性和耐湿热老化性能的影响。研究结果表明：KH-570接枝的EVA胶膜具有相对最好的综合性能,其凝胶率超过90%（即交联度较高）、剥离强度相对最大、1 mm厚EVA胶膜在波长为400～1 000 nm范围内的透光率超过85%且耐湿热老化性能良好。The EVA（ethylene-vinyl acetate copolymer）was grafted and modified when acrylic acid（AA）,methyl methacrylate（MMA）,and γ-methyl acryloyl propyl trimethoxy silane（KH-570）were respectively used asgraft monomers,the influences of graft monomers on some properties（such as crosslinking properties,bondingproperties,transmittance and damp-heat aging resistance）of EVA encapsulants were emphatically discussed. Theresearch results showed that the KH- 570 grafted EVA encapsulant had the relatively best combination propertybecause its gel content was more than 90%（namely higher crosslinking degree）,peeling strength was relativelymaximal,transmittance of EVA encapsulant with 1 mm thickness was more than 85% in the wavelength range of400-1 000 nm,and its damp-heat aging resistance was good.
