摘要：采用乳液聚合合成了以丙烯酸丁酯(PBA)为核、甲基丙烯酸甲酯(PMMA)为壳的胶乳,并将其与纳米碳酸钙浆料混合制备一种新型复合改性剂。重点分析了此方法对纳米碳酸钙的改性效果,研究了复合改性剂增韧PVC的效果。结果表明,通过此法改性的纳米碳酸钙表面亲水-亲油改变,复合改性剂对PVC有较好的增韧效果。
Acrylic latex with PBA as the core and the PMMA as the shell emulsion polymerization. The latex was then mixed with nano-calcium carbonate composite modifier. Analysis of the effect of this mdification effect of the composite modifier on toughening PVC. The nano-CaCO3ehanged from hydrophilic one to lipophilic one, effect on PVC. was synthesized through serum to obtain a novel method on nano-CaCO 3 was studied as well as the results showed that： the property of modified the composite modifier showed good toughening
