Abstract

The invention discloses an electronic cigarette oil-leading rope with carbon nanotube-graphite synergetic enhancement, and a preparation method thereof. The preparation method comprises the following steps of adopting glass fiber as a raw material, using a modified carbon nanotube to modify the glass fiber, and carrying out coupling treatment, so that the carbon nanotube is chemically grafted on the glass fiber to obtain the glass fiber with carbon nanotube enhancement; on the other hand, homogenizing and smashing graphite materials, coupling the surface, and then adding into resin of a polymer to form slurry of the glass fiber; performing blend spinning the glass fiber with carbon nanotube enhancement with graphite-added resin to obtain the glass fiber / polymer composite fiber with carbon nanotube / graphite synergetic enhancement, and interwinding to form the electronic cigarette oil-leading rope. According to the electronic cigarette oil-leading rope provided by the invention, the preparation process is simple and convenient, the problems of poor elasticity, fragility, easiness in breaking, poor abrasion resistance and the like of the traditional oil-leading rope are well solved, meanwhile, the heat transmission capacity is also enhanced, and the phenomenon that an electronic cigarette element is damaged due to dry ashing is avoided.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a method for preparing a carbon nanotube / graphite synergistically reinforced electronic cigarette oil guide rope. Background technique [0002] The oil guide rope in the electronic cigarette is the key part of the atomizer to generate smoke. It guides the smoke oil into the heating wire and atomizes it to form smoke. However, the main component of the traditional electronic cigarette oil guide rope is a composite material of glass fiber / polymer. Although it has good insulation and oil conductivity, it is brittle and has poor wear resistance, and its thermal conductivity is not good, which is prone to dry burning. This phenomenon will affect the taste of e-cigarette smoke. [0003] A carbon nanotube is a tubular carbon fiber with a nanometer diameter. Due to the carbon atoms on its surface and a large number of SP 2 Hybridization exists, the S orbital com...
