Controlled lowering of a polymers glass transition temperature

Номер: US20120237704A1
Автор: Daniel E. Bowen, III

Processes for lowering the glass transition temperature of a polymeric compound relative to the glass transition temperature of a control polymeric compound are disclosed. The methods include the formation of a precursor composition comprising precursor compounds to the polymeric compound dispersed or dissolved in a solvent system. The compounds are partially or fully cured in the presence of the solvent system, which is then substantially removed. After further curing, where necessary, the resulting cured polymeric compound is essentially free of plasticizers, but still has a decreased glass transition temperature relative to the glass transition temperature of a control polymeric compound. Articles of manufacture comprising such polymeric compounds are also disclosed.

The preparation method of epoxy resin for prepreg system and the preparation method of prepreg

Номер: CN107099020A

本发明提供一种预浸料用环氧树脂体系的制备方法,包括以下步骤:将环氧树脂基体在50℃~100℃搅拌,形成组分A;将室温反应性固化剂和潜伏性固化剂混合,形成组分B;及将组分A和组分B以100:10~20的质量比混合反应,得到预浸料用环氧树脂体系。本发明还提供一种预浸料的制备方法。上述预浸料用环氧树脂体系在制备成胶膜时粘度较低,能够保证浸润增强纤维或织物的每根单丝,且由于柔性链段的室温反应性固化剂的加入,使得后续放置时,环氧树脂体系可继续反应,从而提高环氧树脂体系的粘度,降低预浸料的树脂流动度,同时,柔性链段对复合材料具有增韧效果。
