Embodiment 1

[0028] The titanium wire was ultrasonically cleaned with acetone, ethanol and deionized water in turn, and air-dried with nitrogen, and then the titanium wire was placed in 0.5wt% ammonium fluoride in ethylene glycol solution, using it as an anode and applying a voltage of 10V while stirring status response for 10 minutes. After the completion, take out the titanium heating wire, rinse the solution on it with deionized water, and then dry the water in a blast drying oven to obtain a titanium wire with an anodic oxidation layer. Such as figure 1 As shown, the micro-nanopore structure on it.

[0029] Preparation of sol-gel coating: Add 30ml of ethanol, 0.9ml of glacial acetic acid, 2ml of n-hexanol, 5ml of HCl (0.01M), 5ml of methyltriethoxysilane, and 0.5ml of KH550 in a three-necked flask, and stir at room temperature Mix evenly, then add 0.2 g of deionized water, stir for 24 hours, and age at room temperature for 7 days to obtain a sol-gel solution with uniform appearance. ...

Embodiment 2

[0036] As in Example 1, a voltage of 100V was applied.

[0037] Preparation of sol-gel coating: Add ethanol 30ml, glacial acetic acid 0.9ml, n-hexanol 2ml, HCl (0.01M) 5ml, methyltriethoxysilane 5ml, dimethyldimethoxysilane 0.2ml, 0.5ml of KH550, 1ml of perfluorodecylethyltriethoxysilane, stirred and mixed evenly at room temperature, then added 0.2g of deionized water, stirred for 24h, and aged for 7 days at room temperature to obtain the sol-gel glue solution.

[0038] Dilute the obtained sol-gel solution 100 times with absolute ethanol, dip-coat the titanium wire with anodized layer, dry it at room temperature, and then treat it in an oven at 180°C for 3 hours to obtain the titanium heating wire .

[0039] The test results are similar to Example 1.

Embodiment 3

[0041] As in Example 1, a voltage of 60V was applied.

[0042] Preparation of sol-gel coating: Add ethanol 30ml, glacial acetic acid 0.9ml, n-hexanol 2ml, HCl (0.01M) 5ml, methyltriethoxysilane 5ml, dimethyldimethoxysilane 0.5ml, KH550 is 0.5ml, stir and mix evenly at room temperature, then add 0.2g of deionized water, stir for 24h, and age at room temperature for 7 days to obtain a sol-gel solution with a uniform appearance.

[0043]Dilute the obtained sol-gel solution 100 times with absolute ethanol, dip-coat the titanium wire with anodized layer, dry it at room temperature, and then treat it in an oven at 180°C for 3 hours to obtain the titanium heating wire .

[0044] The test results are similar to Example 1.

Abstract

The invention discloses a titanium heating wire with a low surface energy layer. The titanium heating wire comprises an anodic oxidation layer on the surface of a titanium wire and a sol-gel layer onthe surface of the anodic oxidation layer. The invention further discloses a preparation method of the titanium heating wire and an application of the titanium heating wire to reduction of tobacco taradhesion of an electronic cigarette.

Description

technical field [0001] The invention belongs to the field of electronic cigarette materials, and in particular relates to a low surface energy titanium heating wire with low smoke oil adhesion and a preparation method thereof. [0002] technical background [0003] The smoke produced by burning cigarettes contains at least 2,000 kinds of harmful components, among which polycyclic aromatic hydrocarbons such as benzopyrene, benzanthracene, nitrosamines, cadmium, arsenic, β-naphthylamine, etc. have carcinogenic effects. The carcinogens are cyanide, o-cresol, phenol and so on. When smoking, most of the cigarette smoke is inhaled into the lungs, and a small part enters the digestive tract together with saliva. Some harmful substances in the smoke stay in the lungs, and some enter the blood circulation and flow to the whole body. Harmful components in cigarette smoke include carbon monoxide, nicotine and other alkaloids, amines, nitriles, alcohols, phenols, alkanes, alkenes, carb...
