摘　　要：以马来酸酐(MAH)为接枝单体,乙烯-辛烯共聚物(POE)为基体树脂,无味过氧化二异丙苯(BIBP)为引发剂,通过双螺杆挤出机熔融挤出马来酸酐接枝乙烯-辛烯共聚物(POE-g-MAH),以此作为粘接树脂的相容剂。研究了反应温度、螺杆转速及MAH用量对相容剂熔体流动速率、接枝率的影响,以及相容剂在粘接树脂中的应用。通过熔体流动速率仪、傅里叶红外光谱(FTIR)、万能试验机等对相容剂进行表征和分析;再将相容剂、基体树脂、以及相关助剂通过双螺杆挤出机挤出,得到的粘接树脂通过万能试验机检测其力学性能。结果表明,在引发剂BIBP的作用下,MAH可以顺利接枝到POE上,当MAH的添加量为1%(质量分数,下同)、BIBP的添加量为0.1%时,相容剂的接枝率可达0.7%,熔体流动速率为0.691 g/10 min;在粘接树脂配方中加入20%的相容剂后,粘接树脂的拉伸强度达到14.8 MPa,断裂伸长率达到1031.1%,剥离强度达到178 N/25 mm。In this work,POE-g-MAH as a compatibilizer of adhesive resin was prepared through extrusion with a twinscrew extruder using maleic anhydride(MAH)as a graft monomer,polyolefin elastomer(POE)as a matrix resin,and diisopropyl peroxide(BIBP)as an initiator.The effects of reaction temperature,screw speed and MAH amount on the melt flow rate and graft rate of this compatibilizer were investigated and its applications for adhesive resins were explored.The compatibilizer was characterized and analyzed using melt flow rate meter,Fourier transform infrared spectroscopy,and universal testing machine.An adhesive resin was further prepared through melt extrusion with the compatibilizer,matrix resin and related additives,and its mechanical properties were measured using universal testing machine.The results indicated that MAH was successfully grafted onto POE with the aid of odorless diisopropyl peroxide(BIBP)as an initiator.When 1 wt% MAH and 0.1 wt% BIBP were added,the graft rate of compatilizer reached 0.7 wt%,its melt flow rate reached 0.691 g/10 min.The adhesive resin exhibited tensile strength,elongation at break and peel strength of 14.8 MPa,1031.1%,and 178 N/25mm,respectively,when 20 wt% compatibilizer was added into the adhesive resin.
