利用反应性接枝和物理共混两种技术，制备了一种适合于粘接聚烯烃树脂和金属铜的粘接树脂。主要研究了反应性接枝配方和物理共混配方对树脂粘接性能的影响。采用接触角、扫描电子显微镜、能谱等表征和测试手段，对最终的接枝树脂和粘接树脂的极性、粘接性能进行了研究。结果表明，聚乙烯接枝马来酸酐（PE-g-MAH）的最佳配方为：线型低密度聚乙烯90份，高密度聚乙烯10份，马来酸酐1.5份，过氧化二异丙苯0.08份，抗氧剂1010和抗氧剂168分别为0.2份。最高接枝温度为180℃。粘接树脂的最佳配方为：PE-g-MAH 100份，增粘树脂6份，调节剂15份。研制的粘接树脂具有和聚烯烃一样的加工性能和条件，同时表现出极佳的粘接性能，主要用于给水用钢丝增强聚乙烯复合管道。

A novel kind of adhesive resins applied in polyolefin and Cu was prepared by means of both reactive grafting and physical blending technologies. Effects of reactive grafting formulation and physical blending formulation on adhesive properties of adhesive resin were mainly studied. Polarities and adhesive properties of grafted resin and adhesive resin were characterized by means of water contact angle measurement,scanning electron microscope and energy spectrum analysis,respectively. The results display that the optimum formulation of PE-g-MAH is:90 phr linear low density polyethylene ,10 phr high density polyethylene,1.5 phr MAH ,0.08 phr dicumyl peroxide ,0.2 phr antioxidant 1010 ,0.2 phr antioxidant 168. Highest grafting temperature is 180℃.The optimum formulation of adhesive resin is:PE-g-MAH 100 phr,tackifying resin 6 phr,regulator 15 phr. The adhesive resins own the same processing properties and conditions with polyolefin,and excellent adhesive properties,which is mainly applied in steel wires reinforced-polyethylene composite pipes for water supply.
