① 弹性粒子间距影响:弹性体力子间距存在一个临界值。只有当分散相的弹性体粒子之间间距小于临界值时,增韧效果才会出现;
(1) the influence of elastic particle spacing: there exists a critical value for the distance between elastic bodies. Only when the distance between the particles of the dispersed phase is smaller than the critical value, the toughening effect will appear.
② 弹性体含量的影响:如1所述,弹性体粒子之间间距需要小于临界值,只有当弹性体达到一定量之后,才有可能分散之后,间距小于临界值;
(2) the influence of the content of the elastomer: as described in 1, the spacing between the particles of the elastomer needs to be less than the critical value. Only when the elastic body reaches a certain amount, it is possible to disperse, and the distance is less than the critical value.
③ 弹性体粒径的影响:在达到弹性体粒子间距临界值时,在一定量的前提下,弹性体粒径越小,增韧效果越好;
The influence of elastomer size: when the critical value of elastic particle spacing is reached, under a certain amount of elasticity, the smaller the elastic particle size is, the better the toughening effect is.
④ 弹性体Tg的影响:弹性体的Tg越低,柔性越好,塑料增韧性效果越好;
(4) the influence of elastomeric Tg: the lower the Tg of elastomers, the better the flexibility, and the better the toughening effect of plastics.
⑤ 弹性体与树脂相容性影响:相容性太差,粘合力不好,增韧性不佳;相容性太好,有可能形成均相,增韧效果也不好;
(5) the compatibility of elastomer and resin: poor compatibility, poor bonding force, poor toughening, good compatibility, possible formation of homogeneous phase and poor toughening effect.
⑥ 弹性体交联度的影响:交联度过高,弹性体模量过高,不利于增韧效果;交联度过低,弹性体加工过程中易破碎,也不利于增韧。
The effect of crosslinking degree of elastomer is too high, the modulus of elastomer is too high, it is not good for toughening effect, the degree of crosslinking is too low, it is easy to break in the process of the elastomer, and it is not good for toughening.
