小空腔内EVA发泡胶带的黏结性能和发泡行为研究
Study on adhesive and foaming properties of EVA expandable tape for small volumes
摘要
Abstract
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.关键词
