Problems solved by technology

[0003] In the plastic modification industry, inorganic minerals such as talc, mica, calcium carbonate, and wollastonite are generally used as filling and reinforcing components, and the rigidity and heat resistance of nylon materials are improved or improved by blending and modification. properties such as plasticity, mold shrinkage, chemical resistance, surface gloss, and flammability to meet the specific requirements of the final plastic product. However, since the density of these inorganic mineral fillers is often higher than that of plastics, they are The addition of mineral fillers to plastics increases the relative weight of the final product

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a semi-aromatic nylon material and its preparation method and application. Background technique [0002] Semi-aromatic nylon is prepared by melt polycondensation of dicarboxylic acids with aromatic rings and aliphatic diamines. Due to the introduction of aromatic rings into the main chain of polyamide molecules, its heat resistance and mechanical properties are improved. , and reduces the water absorption, so it is a resin with high heat resistance between the general-purpose engineering plastic nylon and the high-temperature-resistant engineering plastic PEEK. [0003] In the plastic modification industry, inorganic minerals such as talc, mica, calcium carbonate, and wollastonite are generally used as filling and reinforcing components, and the rigidity and heat resistance of nylon materials are improved or improved by blending and modification. A series of properties s...
