AI Technical Summary
Existing polyurethane foams used in new energy vehicle batteries have insufficient flame retardancy, and the addition of flame retardants reduces flexibility and vibration damping effect. At the same time, ordinary physical blending methods have problems with poor dispersion uniformity and easy migration and failure of flame retardants.
By preparing unsaturated monomer A containing DOPO structure and unsaturated monomer B containing cashew phenol structure, they are grafted onto the methyl hydrogen silicone oil skeleton by hydrosilylation reaction to form a modifier, which is then introduced into the polyurethane foam system to optimize the chain segment movement ability and carbon layer structure, thereby improving flame retardant performance and noise reduction and vibration damping performance.
It significantly improves the noise reduction, vibration damping, and flame retardant properties of polyurethane foam, enhancing its safety and overall performance.
