Abstract

The invention provides a preparation method for an oil conduction material, and is used for solving the problems that the heat conduction performance, the oil conduction performance and the oil storage performance of the oil conduction material are low in the prior art. The invention provides the preparation method for the oil conduction material, and the preparation method comprises the followingsteps: forming: graphene and/ or graphene oxide is formed into a required shape; when the material contains the graphene oxide, an annealing step is contained before and after the forming step. The annealing step comprises the following step of carrying out annealing on the formed or non-formed graphene oxide to form the oxide. According to the preparation method, the preparation of the grapheneoil conduction material is realized.

Description

technical field [0001] The invention relates to a preparation method of pure graphene as oil-conducting cotton for electronic cigarettes, in particular to a preparation method that does not use harmful substances in the preparation process. Background technique [0002] 1 prior art relevant to the present invention one [0003] 1.1 Technical scheme of prior art one [0004] In the existing patented technology, there is a kind of composite oil-conducting cotton. Graphene is evenly wrapped on the fiber surface of the oil-conducting cotton, which improves the oil-conducting rate and oil storage rate, and improves the thermal stability. [0005] 1.2 The shortcoming of prior art one [0006] The existing technology is to simply wrap graphene on the fiber surface of the oil-conducting cotton. First, the thermal stability is limited by the oil-conducting cotton fiber, and there is a risk of decomposing at high temperature to produce harmful carbides that are not conducive to the ...
