粘合剂组合物、粘合带和粘合结构
Abstract:
本发明提供了一种不含卤素的压敏粘合剂组合物，基于所述组合物的所述总重量计，所述组合物包含(A)15至60重量%的丙烯酸类聚合物、(B)10至50重量%的导热填料和(C)20至50重量%的不含卤素的阻燃剂，其中基于所述组合物的所述总重量的100重量%计，所述组分(C)包含：子组分(C1)，所述子组分包含至少一种有机磷类阻燃剂；以及子组分(C2)，所述子组分包含选自含氮化合物类阻燃剂、石墨材料类阻燃剂、三聚氰胺氰尿酸盐类阻燃剂、金属氢氧化物类阻燃剂、金属氧化物类阻燃剂、除(C1)的所述有机磷类阻燃剂之外的金属磷酸盐类阻燃剂中的至少一种阻燃剂，并且基于所述组合物的所述总重量的100重量%计，所述组合物具有不小于4.0重量%的P含量。本发明还提供了一种不含卤素的压敏粘合带和粘合结构。
Abstract(English):

A halogen-free pressure-sensitive adhesive composition is provided, based on the total weight of the composition, comprising (A) 15-60 wt % of acrylic-based polymer, (B) 10-50 wt % of thermally conductive filler, and (C) 20-50 wt % of halogen-free flame retardant, based on 100% of the total weight of the composition, wherein the component (C) comprises: sub-component (C1) comprising at least one organophosphorous-based flame retardant; and sub-component (C2) comprising at least one flame retardant selected from the group consisting of nitrogen-containing compound-based flame retardants, graphite material-based flame retardants, melamine cyanurate-based flame retardants, metal hydroxide-based flame retardants, metal oxide-based flame retardants, metal phosphate-based flame retardants other than the organophosphorous-based flame retardants of (C1), and the composition has a P content no less than 4.0 wt %, based on 100 wt % of the total weight of the composition. A halogen-free pressure-sensitive adhesive tape and an adhesion structure are also provided.
