Abstract

The invention provides an HTPP nucleating agent and a preparation process thereof. According to the HTPP nucleating agent, the stable state accounts for more than or equal to 95% and the metastable state accounts for more than or equal to 90%. The preparation process includes: preparation of raw materials, compounding mixing of the raw materials and drafting. The compounding mixing of the raw materials includes dissolution, i.e. dissolution of melamine, a melamine salt and abietic acid masterbatch in a 3% ethanol-water solution at 50-60DEG C. The heatproof and impact-resistant HTPP prepared from the HTPP nucleating agent has the characteristics of fast crystallization rate, a semi-crystallization time of less than 200s, a bending modulus of more than or equal to 2545MPa and a tensile strength of 35.6-41.14MPa.

Description

Technical field [0001] The invention belongs to the technical field of PP modification auxiliary agents, and relates to an HTPP nucleating agent, in particular to an HTPP nucleating agent, a preparation process thereof, and application in the preparation of a heat-resistant and impact-resistant HTPP. Background technique [0002] The nucleating agent is suitable for incomplete crystalline plastics such as polyethylene and polypropylene. By changing the crystallization behavior of the resin, it can accelerate the crystallization rate, increase the crystal density and promote the miniaturization of the crystal grain size, so as to shorten the molding cycle and improve the transparency and surface of the product. New functional additives for physical and mechanical properties such as gloss, tensile strength, rigidity, heat distortion temperature, impact resistance, and creep resistance. [0003] Thermoplastics can be used to manufacture a wide range of products. When preparing semi-c...
