in material bad 时, cracks expand to toughening agent dispersion versus pellets separation 歧, toward, from consumption can amount retardant cracks formed 裂缝, and cracks speed development make solid material formed cracking. another, toughening agent dispersion versus in material force 时, also can to adjustment ring oxygen resin separation 子发生 orientation, tensile, deformation, 空洞化 and generate cracks and other many consumption can process, make solid material resistant cracks expand can force improve/increase, toughening agent products tough property obvious reinforcement, solid material strong/high degree, impact strong/high degree, flexural strength and other property can significantly improve/increase, meanwhile make solid material rigid property and 玻璃化 temperature degree decline obvious. introduction new type CTBN modified ring oxygen toughening agent combined formed and its in ring oxygen resin solid system in application and 功效.

     1, in recent years, environmental protection already 经越 越 strong/high, as is white in very important plastics industry, 消费者 and 社会都期待 plastics industry green development, and 国家也出台 very more excellent policy promote green environmental protection plastics, 而随 十八 large 顺利结束, green development plastics industry again by upper 议程, formed is solution issues, how to ring 境, 节约资源, let plastics industry 进入 改革 and production technology, toward green environmental protection 靠拢 转 type 期, as is plastics bottle production 厂家 说, 应该积极响应国家 号召, in innovation add large force degree, Raw Materials, let green 无污染, can more ring utilizing or easy degradation plastics product and 开.

     2, different type type toughening agent , has different toughened mechanism. liquid poly 硫橡胶 can and ring oxygen resin reaction, 引入一部 separation flexible 链段, reduce ring oxygen resin modulus, improve/increase toughened property can, 却牺牲 heat resistant property. liquid 体丁腈橡胶 as is ring oxygen resin toughening agent, room temperature solid 化时几乎无 toughened 效果, bonding strong/high degree decline; has in high temperature solid system, toughened and bonding relatively obvious. 端羧基 liquid 体丁腈橡胶 toughened ring oxygen resin, solid front versus 容, solid rear separation versus, formed “海岛 structure ”, can absorption impact can amount, also basic reduce heat resistant property. T一99 more function ring oxygen solid agent solid ring oxygen resin make crosslinked structure in flexible 链段, generate separation versus structure, in high toughness meanwhile basic reduce heat resistant property.
