摘要
选择了低 密度聚 乙烯片材（ 厚度４ ｍ ｍ 和１２ ｍ ｍ ） 做试 样， 浸泡 在丙 烯酸 水溶 液中 ， 在钴源上 进行共辐 照接枝 ，使其表面 接枝上 丙烯酸单 体，从非 极性 表面 转变 为带 极性 官能 团的 表面 ，从而改 善了聚乙 烯片材 表面粘接 性 能。对 改 性后 的和 原 始的 样片 用 不同 的胶 粘 剂进 行 了粘 接测试，结 果表明：改 性后的 粘接性能 有较大提 高。
In this work the flake materials (thickness=4mm and 1 2mm) of lower density PE are selected as samples By putting them in aqueous solution of acrylic acid, the graft copolymerization is completed by 60 Co γ irradiation So on the surfaces of flake samples the monomer of acrylic acid is grafted, and the samples' surfaces are transformed from non polar ones to the ones with polar groups Thus the surface adhesiveness of PE flake material is modified much better With different adhesives, the adhere links of modified and primary flake samples are accomplished respectively, then the surfaces' adhesive strength of them is measured The measured results show that the surface adhesiveness of modified flake samples is much better than that of primary samples
