Multifunctional additive and preparation method thereof

The invention discloses a multifunctional additive which is prepared by uniformly melting and mixing any two or more of an anti-aging agent, a nucleating agent and a coupling agent. The invention further provides a preparation method of the multifunctional additive. The multifunctional auxiliary agent provided by the invention replaces an existing technical method of respectively adding single-function auxiliary agents, at least two of the anti-aging agent, the nucleating agent, the coupling agent and the like which need to be added are prepared into a compound in advance, and then a polymer material is added to prepare the multifunctional auxiliary agent. Therefore, the problems that a polymer material is easy to age, poor in mechanical property and unsatisfactory in processability, additives are easy to extract and the like are solved. 本申请公开了一种多功能助剂，包括：抗老化剂、成核剂、偶联剂中的任意两种或多种，经熔混均匀，制得多功能助剂。本申请还提供一种多功能助剂的制备方法。本申请提供的多功能助剂，取代现有的单功能助剂分别添加的技术方法，将需要添加的抗老化剂、成核剂、偶联剂等至少两种预先制成复配物，然后再加入聚合物材料，从而解决聚合物材料存在的易老化、力学机械性能不佳、加工性
