The invention provides a compound transparent nucleating agent, a polypropylene material and a preparation method and application thereof. The compound transparent nucleating agent comprises 1,3:2,4-bis(3,4-dimethylbenzene) methylene) sorbitol, chelating agent and sorbitan ester emulsifier. Through the compounding of 1,3:2,4-bis(3,4-dimethylbenzylidene) sorbitol, sorbitol ester emulsifier and chelating agent, it is solved that the transparent nucleating agent cannot be processed at a suitable temperature The problem of achieving good dispersibility can improve the compatibility of the compound transparent nucleating agent with polypropylene, and promote the growth of nucleating agent crystals, thereby reducing the crystallization time of polypropylene and saving production costs. |
