Abstract
The present invention relates to a rigidity-enhancing nucleating agent composition containing hydrotalcite, also relates to thermoplastics containing the nucleating agent composition, and in particular, to nylon containing the nucleating agent composition. The nucleating agent composition contains bis[4-tert-butylbenozic acid]hydroxyl aluminum and hydrotalcite with a weight ratio of 5:1-1:5. The nucleating agent composition has a better nucleating effect, and the resulting nylon products have high tensile strength and bending strength, low impact strength loss, and good thermal resistance. The nucleating agent of the present invention improves the demolding properties during nylon processing and shortens the injection molding cycle, thereby improving the production efficiency. In addition, the nucleating agent not only improves the dimensional stability of products and reduces their shrinkage, but also improves their mechanical properties, transparency, and thermal resistance.
Description
technical field [0001] The invention relates to the field of nucleating agents, in particular to a stiffening nucleating agent composition containing hydrotalcite, and to thermoplastics containing the nucleating agent composition, in particular to nylon containing the nucleating agent composition. technical background [0002] Thermoplastics refer to plastics that soften when heated to flow and harden when cooled. They can be processed into injection molded products with various uses through injection, extrusion and blow molding, such as daily life products, medical appliances, electrical appliances, automobiles and pipes. wait. Thermoplastic polymers involved in the present invention include, but are not limited to, polyolefins (such as polyethylene, polypropylene, polybutylene, and any combination thereof), polyamides (such as nylon), polyurethanes, polyesters (such as polypara ethylene phthalate) and its analogues. [0003] Polyamide is commonly known as nylon. Nylon is...
