摘要
以接枝率不低于2.61％的SBS-丙烯酸（AA）接枝共聚物配制的雨靴等橡胶制品用涂料,涂饰于制品表面,3min内可完全干燥,涂膜不需硫化,其性能优于经硫化的SBS涂膜。该接枝共聚物的合成条件为:溶剂为甲苯,引发剂为过氧化二苯甲酰（BPO）,单体AA采用滴加法,SBS/甲苯为15％（质量）,AA/SBS为10％,BPO/AA为0.6％,80℃（或70℃）,3h（或5h）。
The varnish for rubber goods was prepared using SBS-acrylic acid (AA) graft copolymer with the graft ratio more than 2-61%. When it was painted on the surface of rubber goods such as boots, it could dry up in 3 min at ambient temperature without curing, the SBS-g-AA coating layer was superior in properties to the cured coating layer formed by SBS varnish . The graft copolymerization of AA onto SBS was car-ried out with toluene as solvent, benzoyl peroxide (BPO) as initiator. The monomer AA was added by drip feed method. The graft copolymerization conditions were: SBS/toluene 15%(mass),AA/SBS 10%, BPO/AA 0.6%, at 80℃or 70℃for 3h or 5h.
