1. A method for preparing a bisphenol phosphate hydroxyl aluminum salt nucleating agent, comprising steps of:
(1) adding bisphenol phosphate and alkyl aluminum alcoholate into an organic solvent; reacting at a certain temperature, and obtaining an intermediate; and
(2) adding water into the intermediate obtained through the step (1), then hydrolyzing, and distilling, so as to remove by-product alcohols and the organic solvent; filtering, drying, and finally obtaining the bisphenol phosphate hydroxyl aluminum salt nucleating agent.
