Abstract
The invention relates to the technical field of composite adhesive preparation methods, and provides a preparation method of a polyborosiloxane modified epoxy resin composite adhesive and a composite adhesive, and the preparation method comprises a preparation step of polyborosiloxane, and a preparation step of obtaining the polyborosiloxane, polyborosiloxane and epoxy resin composite adhesive by obtaining and processing a plurality of mixtures, processing polyborosiloxane and epoxy resin to obtain a polyborosiloxane modified epoxy resin composite adhesive; the preparation process is simplified through the preparation step of polyborosiloxane and the preparation step of the polyborosiloxane and epoxy resin composite adhesive, and the prepared polyborosiloxane modified epoxy resin composite adhesive has an excellent flexible protection effect; the acceleration response of the structure under high-speed impact is remarkably reduced, and an obvious suppression effect on interference signals under high frequency is achieved. And meanwhile, the dynamic thermal mechanical performance and the impact resistance and vibration suppression performance are remarkably enhanced.
Description
technical field [0001] The invention relates to the technical field of preparation methods of composite glue, in particular to a preparation method of polyborosiloxane modified epoxy resin composite glue and the composite glue. Background technique [0002] Epoxy resin (EP) is a high molecular polymer. Due to its excellent physical and mechanical properties, electrical insulation properties, adhesive properties and process flexibility, it is widely used in the field of impact protection such as electronic adhesives to protect key The shock and vibration suppression of electronic components has a protective effect. However, in actual application, EP potting materials are difficult to significantly suppress impact and vibration, and the protection ability of electronic components needs to be further improved. [0003] Polyborosiloxane (PBDMS) is a flexible intelligent impact-resistant material, a low-density impact-resistant material whose mechanical properties change with th...
