Abstract

The invention provides a CNT (Carbon Nano Tube) / nylon6 composite material and a preparation method thereof. The CNT / nylon6 composite material comprises a modified CNT and nylon 6, wherein the modified CNT is a CNT subjected to surface modification, and by adopting weight percent of the CNT / nylon6 composite material as reference, the weight percent of the modified CNT is 1wt%-20wt%. The CNT / nylon6 composite material prepared by the invention has the advantages that the tensile strength is high, the yield strength is strong, and the bending modulus is high; especially, the surface resistance of the material is greatly reduced, and the comprehensive performance of the material is excellent; the dispersity of CNT in PA6 is good, the yield of products is high, the addition amount of the CNT is low, the comprehensive performance of the material can be greatly improved only by 1wt%-2wt% of the CNT, and the cost is low, so that the CNT / nylon6 composite material is suitable for large and industrial production.

Description

technical field

[0001] The invention relates to nylon materials, in particular to a carbon nanotube / nylon 6 composite material and a preparation method thereof. Background technique

[0002] At present, the mechanical properties of PA6 (nylon 6) are generally improved by adding glass fiber and carbon fiber. Generally, the amount of glass fiber added is 40wt%-60wt%, and the amount of carbon fiber is 20wt%-30wt%. To a certain extent, the tensile and bending strength of PA6 are enhanced, but a large amount of glass fiber is added. First, the cost is high, but the large amount of glass fiber in nylon 6 also reduces other properties of nylon 6. Therefore, the addition of carbon fiber is more effective. It is more and more favored by the industry, especially the carbon nanotubes currently studied, which have the advantages of one-dimensional nanomaterials, have a huge aspect ratio, and can greatly improve the mechanical properties of PA6, and the tensile strength of CNT (carbon na...
