增韧剂在复合材料等行业的大作用
什么是增韧剂
What is a toughening agent
增韧剂一般都含有活性基团,能与树脂发生化学反应,固化后不完全相容,有时还要分相,会获得较理想的增韧效果,使热变形温度不变或下降甚微,而抗冲击性能又明显改善。一些低分子液体或称之为增塑剂之物加入树脂之中,虽然也能降低脆性,但刚性、强度、热变形温度却大幅度下降,不能满足结构粘接要求,因此,增塑剂与增韧剂是完全不同的。
The toughening agent generally contains active groups, which can react with the resin. After curing, the toughening agent can not be completely compatible, and sometimes it is also phase separation. The toughening agent will get a better toughening effect, make the thermal deformation temperature change or decrease slightly, and the impact resistance performance is obviously improved. Some low-molecular-weight liquids or plasticizers are added to the resin, although they can also reduce brittleness, but the rigidity, strength and thermal deformation temperature drop greatly, which can not meet the requirements of structural adhesion. Therefore, plasticizers and toughening agents are completely different.

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.
