以丙烯酸丁酯、丙烯酸-2-乙基己酯、醋酸乙烯酯、丙烯酸羟乙酯及丙烯酸为单体,以乙酸乙酯和二甲苯为溶剂,通过自由基溶液聚合制得自交联丙烯酸酯共聚物黏料,经添加聚磷酸铵阻燃剂,得到了具有阻燃功能的丙烯酸酯压敏胶.通过控制引发剂用量和单体配比可改善压敏胶因聚磷酸铵加入后压敏性降低的问题;当丙烯酸丁酯、丙烯酸羟乙酯、醋酸乙烯酯、丙烯酸-2-乙基己酯和丙烯酸的质量比为42.6∶4.2∶8.5∶42.6∶2.1,引发剂和聚磷酸铵用量分别为单体总质量的1.4%、28%时,所得压敏胶阻燃性能和常规性能均与进口阻燃压敏胶BMS 5-133D的性能相当.

A serial of self cross-linking acrylate pressure sensitive adhesive,based on butyl acrylate (BA),2-ethylhexyl ester (2-EHA),vinyl acetate (VAc),2-hydroxyethyl acrylate(HEA) and acrylic acid (AA) as monomers,xylene and ethyl acetate as solvent,are synthesized by solution polymerization.By adding ammonium polyphosphate as flame retardants a flame retardant acrylate pressure-sensitive adhesive is prepared.The dosage of initiator and monomers has great influence on the cohesiveness of pressure-sensitive adhesive.The addition of flame-retardant can improve the flame retardancy of pressure sensitive adhesive flame,and also enhance the bonding performance.When the mass ratio of BA,2-EHA,VAc,HEA and AA is 42.6∶4.2∶8.5∶42.6∶2.1,and adding the initiator and ammonium polyphosphate as 1.4% and 28%,respectively,of all monomers' mass in them,the prepared pressure sensitive adhesive equals an imported sample,BMS 5-133D,in performance.
