摘要
以丙烯酸丁酯(BA)、丙烯酸异辛酯(2-EHA)、丙烯酸(AA)、丙烯酸羟乙酯(HEA)、甲基丙烯酸乙酯(EMA)、烯丙基磷酸二乙酯(DEAP)共聚制得了含磷阻燃丙烯酸预聚树脂,再添加一定量环三磷腈阻燃剂APPCP制备阻燃丙烯酸压敏胶,解决了传统单一使用外添加型阻燃剂由于加入量过多而造成压敏胶粘合性能(包括初粘性、剥离强度、持粘性)降低以及聚磷酸铵、氢氧化镁等常用固体阻燃剂不易与丙烯酸压敏胶相溶且制成胶黏剂后保质期较短的问题。当DEAP用量为单体总质量10%和APPCP为丙烯酸预聚树脂质量的10%时,最终制得胶带的粘合性能最优,燃烧等级可达VTM-0级。
The phosphorus flame retardant acrylic prepolymerization resin, based on butyl acrylate (BA), 2-ethylhexyl ester (2-EHA), acrylic acid (AA), 2-hydroxyethyl acrylate (HEA), ethyl methacrylate (EMA), and diethyl allylphosphonate (DEAP) as monomers, which is added to a certain amount of organophosphorous flame retardants (APPCP) so as to produce the flame retardant acrylic pressure sensitive adhesive. This method will solve the problems caused by an extra amount of external added flame retardant, such as degradation of adhesive performance and bad solubility of acrylic pressure sensitive adhesive and solid flame retardant agent like ammonium polyphosphate and magnesium hydroxide as well as a shorter guarantee period of adhesive. When DEAP accounted for 10% of the total mass of monomer and APPCP accounted for 10% of acrylic prepolymerization resin quality, the adhesive tape has an optimal performance, which burning level can reach VTM-0 level.
