Disclosed are a ²-crystal form nucleating agent composition for polypropylene and use thereof. The composition is prepared by proportionally mixing barium tetrahydro phthalate, calcium tetrahydro phthalate with adjuvant hydrotalcite or calcium carbonate. The composition has better functions than a single-component ² nucleating agent. The impact strength of polypropylene subjected to modification of the ²-crystal form nucleating agent composition can be improved by up to 6 times, and the heat distortion temperature is improved by about 10°C to 20°C. In addition, while the impact strength is improved, the flexural modulus of polypropylene can also be improved. The ²-crystal form nucleating agent composition for polypropylene of the invention can be widely used in the processing application of polypropylene resin. |
