High-toughness yellowing-resistant and easy-to-demold toughened nylon 6 composite material and preparation method thereof

Abstract

The invention discloses a high-toughness yellowing-resistant and easy-to-demold toughened nylon 6 composite material and a preparation method thereof. The nylon 6 composite material is composed of thefollowing raw materials in percentage by mass: 70-88% of nylon 6; 5-10% of a toughener; 4-8% of polyethylene; 0.4 to 0.8% of a lubricant; 0.4 to 0.8 percent of an antioxidant; and 0.2-0.4% of a heatstabilizer. The nylon 6 composite material has the advantages that the prepared nylon 6 composite material has the advantages of high toughness, yellowing resistance and easiness in demolding, is suitable for nylon materials needing high toughness, such as automobile inhaul cables and the like, can avoid the defects of yellowing of a workpiece and easiness in sticking of the workpiece to a mold due to local overheating in a continuous production process, and can greatly improve the qualification rate and the production efficiency of the workpiece; and moreover, the preparation process is simple, the cost is relatively low, and large-scale industrial production is easy to carry out.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a high-toughness, yellowing-resistant, easy-release toughened nylon 6 composite material and a preparation method thereof. Background technique [0002] Nylon 6 is an engineering plastic with the widest range of uses and the largest variety. The material has good mechanical properties, heat resistance, wear resistance, chemical solvent resistance, self-lubrication and certain flame retardancy. It has excellent processing performance and can be integrated into complex structural parts. It is widely used in automobiles, electronic appliances, machinery, rail transit, sports equipment and other fields. [0003] However, nylon 6 has disadvantages such as low impact strength in dry state and low temperature, and poor mold release during injection molding. In the actual application process, it is often necessary to modify these shortcomings. Common nylon 6 modification meth...
