Abstract

The invention discloses a thermoplastic elastomer composite, a component of electronic cigarette and a method of preparing the component of electronic cigarette. The thermoplastic elastomer composite comprises 65-85 weight % of a main body material, 10-25 weight % of a microspheres foaming agent and 5-10 weight % of an agent. The component of electronic cigarette made of the thermoplastic elastomer composite, has high elasticity and a wide hardness adjusting range, can be adjusted according to users' requirements, and has good taste and feel. The component can be provided with decorative patterns that are similar to tobacco leaves in production, and can simulate appearance of a real cigar and visual effects of real tobacco of cigarettes. The component has high elasticity, and it is non-toxic and non-pollution. The method can be carried out in a simple manner, and can improve the production efficiency.

First claim

What is claimed is:

1. A method for producing an electronic cigarette component made of a thermoplastic elastomer composite material, the method comprising the following steps:
S 01 : with respect to a total weight of the thermoplastic elastomer composite material, weighing 70-85 weight % of a main body material, 10-25 weight % of a microsphere foaming agent, and 5-10 weight % of an additional agent, and mixing the weighed main body material, microsphere foaming agent, and additional agent together;
S 02 : mounting a mould on an injection moulding machine and adjusting a temperature of the mould;
S 03 : closing the mould;
S 04 : injecting the mixture of the weighed main body material, microsphere foaming agent, and additional agent into the mould at the adjusted temperature, the injecting taking place at an injection speed under a preset injection pressure and at a preset injection temperature, and the injected mixture being molten within the mould;
S 05 : solidifying the molten, injected mixture of the main body material, microsphere foaming agent, and additional agent in the mold under a preset maintenance pressure for a predetermined time period and then cooling the solidified mixture of the main body material, microsphere foaming agent, and additional agent together with the mould for a cooling time period so as to form the electronic cigarette component; and
S 06 : opening the mould and removing the electronic cigarette component from the mould,
wherein the electronic cigarette component is at least one of a suction nozzle cover, a protecting sleeve, a crown top, and a suction nozzle, any of which can be provided with decorative patterns similar to tobacco leaves,
wherein the adjusted temperature of the mould is selected from a range of 40° C. to 50° C.,
wherein the preset injection pressure is selected from a range 40 Mpa to 60 Mpa and the preset injection temperature is selected from a range of 160° C. to 200° C.,
wherein the injection speed is selected from a range of 20 cm 3 /s to 40 cm 3 /s,
wherein the predetermined time period is selected from a range of 10 s to 150 s,
wherein the cooling time period is selected from a range of 15 s to 20 s, and
wherein the main body material is any one of a thermoplastic polyurethane, a thermoplastic elastomer, and a thermoplastic rubber.

2. The method for producing an electronic cigarette component of claim 1 ,
wherein the additional agent comprises 30-40 weight % of a toughener, 10-20 weight % of an activating agent, 10-20 weight % of a cross linking agent, and 30-40 weight % of a toner,
wherein the toughener is any one of a styrene-butadiene-styrene block copolymers, an ethylene-vinyl acetate copolymer, and a chlorinated polyethylene,
wherein the activating agent is any one of a calcium oxide, a zinc carbonate, and a stearic acid,
wherein the cross linking agent is any one of a dicumyl peroxide, a di-tert-butyl peroxide, and a lauroyl peroxide, and
wherein the toner is any one of a fluorescent red, a titanium dioxide, a fluorescein, and a permanent yellow.
