摘要
利用熔融接枝法制备了马来酸酐接枝乙烯-辛烯共聚物(POE-g-MAH),将POE-g-MAH与线型低密度聚乙烯(LLDPE)共混后与铜片进行热复合。研究了热复合工艺、POE-g-MAH接枝率及含量、苯乙烯-异戊二烯-苯乙烯共聚物(SIS)含量等因素对共混物黏结性能的影响。结果表明:随着POE-g-MAH接枝率和含量的增大,共混物的黏结性能增强,但POE-g-MAH含量过多将导致共混物黏结性能下降,其最佳用量为30phr;在LLDPE/POE-g-MAH共混物中加入20phrSIS可明显提高共混物的黏结性能;最佳热复合工艺条件:温度190℃,压力2MPa,时间1min。
POE-g-MAH was prepared by melt grafting. LLDPE/POE-g-MAH blend was compounded with copper sheet by heating. The effects of heat compounding technology, graft ratio and content of POE-g-MAH, SIS content on adhesive property of the blend were studied. The results showed that with the increase of graft ratio and content of POE-g-MAH, the adhesive property of the blend increases, but excessive POE-g-MAH results in the decrease of the adhesive property of the blend, the optimum content is 30phr; the addition of 20phr SIS into LLDPE/POE-g-MAH blend improves the adhesive property of the blend obviously; the optimum heat compounding technology is temperature 190℃, pressure 2MPa, time lmin.
