增韧剂作用
Toughening agent
增韧剂与塑胶混合在不影响塑料本身物性的前提下提高它的抗冲击强度,韧性,拉伸强度,耐曲折性,抗寒性,缓解热胀冷缩,降低成本。
The toughening agent and plastic mixture can improve its impact
strength, toughness, tensile strength, zigzag resistance, cold
resistance, heat expansion and shrinkage, and lower cost, without
affecting the physical property of plastic.
增韧剂是具有降低复合材料脆性和提高复合材料抗冲击性能的一类助剂。可分为活性增韧剂与非活性增韧剂两类,活性增韧剂是指其分子链上含有能与基体树脂反应的活性基团,它能形成网络结构,增加一部分柔性链,从而提高复合材料的抗冲击性能。非活性增韧剂则是一类与基体树脂很好相溶、但不参与化学反应的增韧剂。
Toughening agent is a kind of additive which can reduce the
brittleness of composites and improve the impact resistance of
composites. It can be divided into two types: active toughening agent
and inactive toughening agent. Active toughening agent refers to the
active group on its molecular chain that can react with matrix resin. It
can form a network structure and increase a part of the flexible chain,
thus improving the impact resistance of the composite. The inactive
toughening agent is a kind of toughening agent which is well soluble
with the matrix resin but does not participate in the chemical reaction.
