Problems solved by technology

However, there is a strong intermolecular force between the graphene nanosheets, which makes the graphene sheets easy to agglomerate and difficult to disperse in the resin, which will greatly reduce the toughening and strengthening effect of the graphene filler on the resin.

Abstract

The invention provides high-strength anti-puncturing graphene modified plastic which comprises the following materials in parts by weight: 40-80 parts of PA66, 30-60 parts of glass fiber, 0.8-3 parts of graphene, 0.5-1.5 parts of nanometer zinc oxide, 0.3-2 parts of surface active agent, 0.1-1 part of dispersing agent, 0.5-2.5 parts of coupling agent and 0.1-0.6 part of antioxidant. According to the invention, PA66 is used as a plastic substrate and the graphene is utilized to modify, so that the mechanical property of the plastic is promoted; the graphene is subjected to nanometer zinc oxide intercalated modification, so that the dispersing performance of the graphene is obviously promoted; the other auxiliary additives jointly have a cross-linking effect on the plastic, so that the toughness of the plastic is greatly promoted; and the plastic has an excellent anti-puncturing property and is light and practical.

Description

technical field [0001] The invention relates to the technical field of plastic modification, in particular to a high-strength puncture-resistant graphene modified plastic. Background technique [0002] Puncture-resistant materials require high shear strength, impact resistance, and high modulus, so special materials are required. In many countries including China, the use of firearms is strictly restricted to a certain extent, but threats from sharp instruments such as daggers and bayonets can be seen everywhere, which makes the research and development of stab-resistant materials a hot research topic. Puncture materials have the disadvantages of heavy weight, large thickness, and high price, and poor comfort when used as stab-resistant clothing. Graphene is a new sheet-like material composed of carbon atoms, which has excellent heat resistance, mechanical properties, electrical properties, transport properties, gas barrier properties and thermoelectric properties. Graphen...
