Abstract
The invention discloses a high-fluidity high-temperature nylon material and a preparation method. Because a stabilizer is added in the material, the high temperature resistance effect of nylon is increased, and a lubricant is used to make the nylon have higher fluidity and mold release performance and easy in molding by processing, in addition, due to the addition of a nucleating agent, the flow performance of products is increased, the molding time of the products is shortened and the tensile, impact and other properties of the products are improved. Glass fiber is matched with grafted POE, thus the toughness of the products is greatly improved, so that the products can be used in a shock-resistant environment. Finally through the stabilizer, nucleating agent, lubricant, glass fiber and grafted POE matching with each other, the fluidity of the products is improved, and meanwhile the high temperature and impact resistance of the products are greatly improved, the molding time of the products is significantly shortened, and the production cost of the products is effectively reduced.
Description
technical field [0001] The invention belongs to the technical field of nylon materials, and in particular relates to high-fluidity high-temperature nylon materials and a preparation method. Background technique [0002] Polyamide (PA), commonly known as nylon, has good comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubricating properties, and has a low coefficient of friction, certain flame retardancy, and is easy to processing. There are many varieties of PA products, including PA6, PA66, PAll, PAl2, PA46, PA610, PA612, PAl010, etc., as well as many new varieties such as semi-aromatic nylon PA6T and special nylon developed in recent years. Because nylon has many characteristics, it is widely used in automobiles, electrical equipment, mechanical parts, transportation equipment, textiles, and papermaking machinery. With the miniaturization of automobiles, the high performance of electronic and electr...
