Abstract
The invention relates to a hydrotalcite-containing stiffening nucleating agent composition and also relates to a thermoplastic plastic containing the nucleating agent composition and particularly relates to nylon containing the nucleating agent composition. The nucleating agent composition contains di-[4-tert-butyl benzoic acid]hydroxyl aluminium in a weight ratio of (5:1)-(1:5). The nucleating agent composition has a better nucleating effect, and the obtained nylon product has high tensile and bending strength, low loss of impact strength, good heat resistance and the like. By adopting the nucleating agent provided by the invention, the demoulding property in the nylon processing process is improved, the injection moulding cycle is shortened, and the production efficiency is improved; and moreover, the dimensional stability of the product is higher, the shrinkage is reduced, and the mechanical properties, product transparency and heat-resistance temperature of the product are improved.
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...
