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.

一, toughening agent classification

toughening agent can separation is type toughening agent and thermoplastic property elastomer type toughening agent:

（1）橡胶 type toughening agent type toughening agent product types main/primary has liquid poly 硫橡胶, liquid acrylic ester 橡胶, liquid poly butadiene 橡胶, 丁腈橡胶, 乙丙橡胶 and 丁苯橡胶 and other.

（2） thermoplastic property elastomer thermoplastic property elastomer is type in normal temperature lower 显示橡胶 elastic property, in high temperature lower also can molding combined formed material. therefore, this category of polymer has and thermoplastic property plastics features, it can as is composite/compounding material toughening agent, also can as is composite/compounding material 基体材 material. this category of material main/primary polyurethane ester type, styrene type, polyolefin type, polyester type, 间规1,2- poly butadiene type and polyamide (PA) type and other product, currently as is composite/compounding material toughening agent use relatively more is styrene type and polyolefin type.

toughening agent classification and applications

二, toughening agent selection 原则

1. ring oxygen resin agent use selection liquid 体丁腈橡胶, 端羧基 liquid 体丁腈橡胶, poly 硫橡胶, liquid silicon 橡胶, polyether, polysulfone (PSU), polyimide (PI), nano carbon acid 钙, nano oxidation titanium and other;

2. aldehyde resin agent can selection 羧基丁腈橡胶, liquid 体丁腈橡胶, polyethylene (PE) alcohol shrink aldehyde, polyether 砜, polyphenylene oxide (PPO) ketone. water solvent property aldehyde resin 以羧基丁腈胶乳, polyethylene (PE) alcohol as toughening agent;

3. fast solid acrylic ester structure agent selection acrylic ester 橡胶, 羧基丁腈橡胶, chlorine 丁橡胶, chlorine polyethylene (PE), ABS resin and other;

4. α-氰基 acrylic ester agent selection acrylic ester 橡胶, ABS, SBS, SEBS and other;

5. saturated and polyester resin agent selection liquid 体丁腈橡胶, polyethylene (PE) alcohol shrink aldehyde, poly acid ethylene and other;

6. aldehyde resin agent can selection poly acid ethylene emulsion, polyethylene (PE) alcohol and other.

三, toughening agent applications

toughening agent is tool has reduce composite/compounding material property and improve/increase composite/compounding material impact resistant property can type additives. can separation is active property toughening agent and non active property toughening agent type, active property toughening agent is its separation upper has can and resin reaction active property 基团, it can formed structure, increase separation flexible 链, from improve/increase composite/compounding material impact resistant property can. non active property toughening agent is type and resin very good versus solvent, 但不参 and chemical reaction toughening agent.
