AI Technical Summary

Problems solved by technology

However, in the above-mentioned disclosed technical solutions, the modifiers used are all pure elastomers, and the price of these materials is relatively high, resulting in low cost performance of the prepared materials
In addition, because the fluidity of the toughening agent has not been effectively improved, its dispersion performance during the modification process and the fluidity of the modified nylon composite material are not good, which will not only affect the subsequent material molding and production, but also the modification The performance of the agent has not been fully utilized, therefore, it has certain limitations
