Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a polymer nano-modified nylon 11 composite material and a preparation method thereof. Background technique [0002] The large family of nylon is mainly divided into three categories: (1) Aliphatic nylon (2) Aromatic nylon (3) Aliphatic-aromatic nylon. At present, in industrial production, nylon 66 and nylon 6 are the most widely used, and the output is also the largest. Most, they are aliphatic nylons. The output of other varieties of nylon products is small. The chemical name of nylon 11 is polyundecalactam. It is a long carbon chain high-polymerization soft nylon synthesized based on castor oil. Its density is relatively low, only 1.04g / cm 3 ; Stable chemical properties, no reaction with general acid-base and oxidizing agents; low water absorption, excellent barrier properties; good dimensional stability, outstanding mechanical properties.
