摘　　要：通过聚烯烃改性技术分别制备出具有耐候性能和粘接性能的改性聚烯烃材料,再将这些改性聚烯烃材料通过共挤吹膜工艺一体化成型,制备兼具耐候性能和粘接性能的功能性聚烯烃胶膜。对该胶膜的加工成膜、耐候性能和粘接性能进行进一步评估和研究。研究结果表明:胶膜内、中、外三层材料的厚度比例约为28∶31∶41时,三种材料下料、塑化、吹胀成膜等加工性能良好,胶膜横向和纵向的力学性能均良好,对钢板、铝板、镀锌板均有良好的粘接效果。当其作为金属表面涂层使用时,具备一定的耐酸碱腐蚀性能,并且胶膜与金属形成的粘接界面性能稳定可靠,耐气候老化和耐热氧老化性能优异,可作为具有耐候性和粘接功能的金属复合材料涂层使用。Modified polyolefin materials with weather-resistance and bonding properties were prepared separately by using polyolefin modification technology,and then these modified polyolefin materials were integrated through molding process of co-extrusion film blowing to prepare functional polyolefin adhesive film with both weather-resistance and bonding properties.The processing,weather resistance,and bonding properties of adhesive film were further evaluated and studied.The research results showed that,when the thickness ratio of the inner,middle,and outer layers of adhesive film was about 28∶31∶41,the three materials had good processing properties such as cutting,plasticizing,and blowing to form a film.The mechanical properties of adhesive film in both horizontal and vertical directions were good,and it had good bonding effects on steel plate,aluminum plate,and galvanized plate.When used as the coating of metal surface,it had a certain degree of acid and alkali corrosion resistance,and the adhesive interface between the adhesive film and the metal was stable and reliable.It had excellent weather resistance and heat and oxygen aging resistance,which could be used as the coating of metal composite materials with weather resistance and bonding functions.
