Abstract

The invention discloses a method for preparing carbon fiber and a nano material from waste liquid oil as a raw material, and the method comprises the following steps: pretreating at least two kinds of waste liquid oil for removing impurities, adding 58-degree hardened oil, ms-emulsifier, dimer acid, dioctyl sebacate, oleic acid, light oil, and tung oil for emulsifying by cross-mixing, after modifying and copolymerizing and other effects, standing for layering, and preparing a bottom layer part by drawing, pre-oxidation, carbonization, graphitization, surface treatment, coiling and other steps to obtain the carbon fiber, and preparing an upper layer part into the composite nano material. By recycling of the waste liquid oil, energy is saved, sustainable development is realized, and manufacturing cost of the carbon fiber is reduced. The method has mild processing conditions, can be carried out at normal temperature, is suitable for actual production and application, expands the sources of raw materials for preparing the carbon fiber, and has high economic benefits.

Description

technical field [0001] The invention relates to a regeneration process of waste liquid oil, in particular to a method for preparing carbon fibers and nanometer materials by using waste liquid oil as a raw material. Background technique [0002] Waste liquid oil refers to gear oil, mechanical oil, hydraulic oil, waste engine oil, transformer oil, lubricating oil, rubber oil, plastic oil, coal tar, etc. replaced from various machinery, vehicles, ships, etc., mostly with high boiling point, High molecular weight hydrocarbon and non-hydrocarbon mixtures. Due to impurities such as dust, other miscellaneous oils, and metal powder produced by mechanical wear mixed in during use, the color becomes black, the viscosity increases and gradually deteriorates, and organic acids, colloids, etc. are produced, making it difficult to continue to use. A large amount of waste liquid oil is produced every year and discarded as waste, causing environmental pollution and wasting resources. [0...
