摘要:采用4,4-氧代双苯磺酰肼(OBSH)作为发泡剂、以过氧化苯甲酰(BPO)作为交联剂、C9树脂作为增黏剂制备了乙烯-乙酸乙烯酯(EVA)发泡胶带,研究组分对2D发泡胶带使用性能的影响和机理。结果表明,在合适的EVA/BPO/OBSH/C9(100/3/3/40)条件下,发泡胶带能够在170℃和205℃下发泡。发泡胶带具有良好的使用性能,膨胀率超过2倍,不发生挂流,表面平整。同时,发泡胶带的拉伸强度高于5 MPa,断裂伸长率超过240%,吸水率低于5%。
This study prepared a series of ethylene?vinyl acetate(EVA)expandable tapes by using 4,4?oxobenzenesulfo?nyl hydrazine(OBSH)as foaming agent,benzoyl peroxide(BPO)as crosslinking agent,and C9 resin as a tackifier.The effect and mechanism of components on the performance of 2D foam tape were studied.The results indicated that,under the proper blending ratio of EVA/BPO/OBSH/C9(100/3/3/40),the expandable tape could be foamed at both 170℃and 205℃.The expansion rate of the expandable tape exceeded 2 times.And the surfaces of foams were smooth and without irreversible flowing.The tensile strength,the elongation at break and the water absorption of the expansion tape was 5 MPa,240%,and less than 5%,respectively.
