Abstract

The invention discloses an electronic cigarette oil-leading rope with carbon nanotube interface enhancement, and a preparation method and a product thereof. The preparation method comprises the following steps of adopting glass fiber as a raw material, and using a carbon nanotube modified by mixed acid to modify the glass fiber, so that the carbon nanotube is chemically grafted on the glass fiber; processing through a coupling agent, performing blend spinning with resin to obtain glass fiber / polymer composite fiber with carbon nanotube interface enhancement, and interwinding to form the electronic cigarette oil-leading rope. The glass fiber / polymer composite fiber with carbon nanotube interface enhancement has favorable toughness and heat-transmission capacity, and the preparation process is simple and convenient. The electronic cigarette oil-leading rope provided by the invention not only well solves the problems of poor elasticity, fragility and easiness in breaking of the traditional oil-leading rope, 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 preparation method of an electronic cigarette oil guide rope reinforced by a carbon nanotube interface. 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 composition...
