摘要

首次开发了用于通过接触模塑制造复合材料的粘合剂，包括ED-20环氧树脂和热塑性聚氨酯改性的三乙烯四胺。对于固化的粘结剂，与未改性的样品相比，耐磨性指数增加了2.3 arb。单位。使用该粘合剂制造的玻璃增强塑料具有最大载荷下弯曲应力和弹性模量分别增加到522 MPa和16.0 GPa的特点。

Development of Epoxy-Based Binders and Triethylenetetramine (TETA) Modified with Thermoplastic Polyurethane

For the first time, binders have been developed for creating composite materials by contact molding, including ED-20 epoxy resin and triethylenetetramine modified with thermoplastic polyurethane. For cured binders, compared to an unmodified sample, the abrasion resistance index increases by 2.3 arb. units. Glass-reinforced plastics manufactured using the developed binders are characterized by increased values of bending stress at maximum load and elastic modulus up to 522 MPa and 16.0 GPa, respectively.
