The invention relates to the technical field of liquid crystal polymers, in particular to a preparation method of a high-purity LCP material. The LCP material is prepared through a two-step method. Firstly, a specific catalyst is added to enable HBA/HNA and acetic anhydride to be subjected to a collaborative optimization reaction, so that complete acetylation of HBA/HNA is guaranteed to the maximum extent. Then, the ABA, ANA and catalyst after acetylation and the reaction conditions are controlled, and the purity of TLCP is improved by synergistically optimizing process parameters, so that the prepared LCP material is excellent in comprehensive performance and can better meet application requirements. In addition, the preparation method disclosed by the invention is simple in overall process and easy to operate, meets the requirements of large-batch production and manufacturing, and has a good application prospect.
