      PC toughening agent versus large 家都知道 good toughened product is can 帮助我们 product has more good property can, that toughening agent property can in use rear is in 哪方面呢?

 

       1, PC toughening agent is can increase agent film flexibility property material 质. certain hot solid property resin agent, ring oxygen resin, aldehyde resin and saturated and polyester resin agent solid rear elongation low, property relatively large, bonding 部位承受 outer force very easy generate cracks, speed expand 展, 导致胶层 cracking, resistant fatigue, can as is structure bonding use. therefore, must method reduce property, increase large tough property, improve/increase strong/high degree.

 

       2, can decrease low property, increase tough property, also effect/influence agent other main/primary property can material is toughening agent. toughening agent generally has active property 基团, can and resin chemical reaction, solid rear full versus 容, has also need separation versus, obtain relatively toughening agent toughened 效果, make heat deflection temperature (HDT) or decline micro, impact resistant property can also obvious improvement. low separation liquid or is increase agent material add resin in, although can reduce property, rigid property, strong/high degree, heat deflection temperature (HDT) large degree decline, can meet/satisfy structure bonding requirements, therefore, increase agent and toughening agent is full different.

 

       3, has type polymer/macromolecule combined material, can and resin mixed solvent, has active property 基团, can and resin solid reaction, improve/increase fracture elongation and impact strong/high degree, heat deflection temperature (HDT) has decline, this type of material 质称之 is increase agent （flexibizer）, commonly used has liquid poly 硫橡胶, liquid 体丁腈橡胶, due to it and resin amount combined, can made formed structure agent, therefore will increase agent toughening agent type. increase and toughened is versus 互关联 also same concept, 但实际 upper very difficult 严格区 separation 开. from upper toughened and increase different, PC toughening agent toughened it make material overall 柔化, is will ring oxygen resin solid material versus system formed more versus system, toughening agent poly formed pellets in ring oxygen resin crosslinked 网络构 formed versus in formed dispersion versus, resistant cracking property can 发生突变, fracture tough property significantly improve/increase, force property can, heat resistant property loss relatively small.
