PC toughening agent nano pellets filling polymer must achieve nano pellets and polymer in nano degree upper uniform dispersion, can to relatively good reinforcement, toughened 效果. therefore, using/adopting nano pellets modified polymer, 应当进行适当 surface treatment, reduce pellets surface can, increase process in pellets and between interface versus function, improve/increase machine 械剪切 force, most to nano pellets uniform dispersion 效果.

     1, PVC toughening agent modified methods main/primary separation chemical method and material method large type. chemical modified method is through in separation in flexible 链段而改变PVC separation structure,以达 to toughened 目,包括 copolymer, crosslinked, grafting and other. material modified method through machine methods will solvent liquid or emulsion and other mixed combined modified. due to or technology and other causes,PVC toughened modified most 经济实 use methods also is material blending method.

     2, in ring oxygen solid system in new type CTBN modified ring oxygen toughening agent, can improve/increase solid material strong/high degree, impact strong/high degree, flexural strength and other property can. strong/high degree, impact strong/high degree property can. can 看出, add modified 1300*13 CTBN and modified ring oxygen toughening agent 1300*13 or 1300*8 rear, products strong/high degree and impact strong/high degree relatively add toughening agent comparison, add modified 1300*13CTBN15份, PC toughening agent impact strong/high degree relatively toughened front has obvious improve/increase, 但剪切 strong/high degree has obvious improve/increase; add and other amount modified ring oxygen toughening agent 1300*13 or 1300*8 rear, its strong/high degree and impact strong/high degree has relatively large improve/increase, and Model/Grade 1300*13CTBN modified ring oxygen toughening agent is most 佳.
