When the components of the liquid toothpaste are refined and uniform dispersion occurs, the specific surface area of each component is increased, so that the amount of bubbles is generated, and the adsorption occurs well on the organosilicon compound layer 4 and is more firmly fixed. In addition, the enlarged specific surface area of the liquid toothpaste component reduces the drying time of the liquid toothpaste layer (3). In addition, the liquid toothpaste of the present invention does not contain an abrasive component, thereby causing cervical abrasion, thereby preventing periodontal disease such as hypersensitivity to teeth. In addition, by reducing the chemical additives contained in the liquid toothpaste, it is possible to improve dental health.

Toothbrush coated with liquid toothpaste

In the liquid toothpaste described above, the liquid toothpaste layer 3 is applied to the organosilicon compound layer 4 formed on the bristles 2. The organosilicon compound layer 4 is formed by hydrophilic treatment of an organosiloxane as a source gas by atmospheric pressure plasma. Atmospheric pressure plasma apparatus has the advantages of low cost, low process temperature, and can perform the process continuously. Specifically, a gas nozzle is disposed between the two metal electrodes to discharge the gas required in the process toward the bristle 2. At this time, a plasma is formed between the metal electrode and the ground to convert the gas discharged through the gas nozzle into a plasma state. Gases used in the present invention include an organosiloxane source gas, a carrier gas for loading and moving the source gas, an inert gas for stabilizing the plasma, and an oxidant gas for generating an oxygen plasma.

The organosiloxane, which is the source gas, is applied to the surface of the bristles 2 by the organosilicon compound produced through the atmospheric pressure plasma apparatus. At this time, the source gas has an adequate vapor pressure in which a sufficient amount of the compound can be included in the carrier gas while using the excess heating to volatilize it so as not to reach the spontaneous ignition temperature of the mixture. The organosiloxane source is preferably tetramethyldisiloxane (TMDSO), hexamethyldisiloxane (HMDSO), tetraethylorthosilicate (TEOS) and hexamethylcyclotrisiloxane (HMCTSO), wherein HMCTSO is C ₆ H ₁₈ O ₃ It is more preferable because it has a chemical structure of Si ₃ and has a relatively higher vapor pressure than other materials even at atmospheric pressure.

The source gas is carried in a well known carrier gas and mixed with an inert gas to stabilize the formation of the plasma and carried to the gas nozzle. The inert gas may be any one selected from nitrogen gas, argon gas, neon and helium gas. When considering the stability of the plasma, helium gas is preferable, but even if nitrogen gas is used, nitrogen gas may be used since the hydrophilic effect of the present invention is sufficiently expressed.

As described above, when the organosiloxane gas is subjected to atmospheric pressure plasma treatment, an organosilicon compound is generated. The organosilicon compound serves to improve the adhesion between the bristles (2) and the liquid toothpaste layer (3). Although the thickness of an organosilicon compound changes with the characteristics of the bristles 2, 50-2,000 GPa is preferable. The organosilicon compound according to an embodiment of the present invention may be SiOxCy (−H), where 1.0 <x <2.4 and 0.0 <y <1.0 are satisfied. SiOxCy (-H), the organosilicon compound, has a contact angle of about 80 °. Subsequently, the surface of the brush head 2 coated with the organosilicon compound is plasma-treated using an oxygen plasma generated by an oxidant gas through an atmospheric pressure plasma apparatus. The oxidant gas includes O ₂ , O ₃ , NO, NO ₂ , N ₂ O, N ₂ O ₃ and N ₂ O ₄ . Preferred oxidant is oxygen (O ₂ ). If desired, additional gases such as CO ₂ and N ₂ may be included. Preferred gas mixtures are air or a mixture of oxygen and nitrogen. When the organosilicon compound is subjected to plasma treatment, the contact angle of water is about 20 degrees. Accordingly, when the oxygen plasma treatment is performed, the adhesion to the bristles 2 is greatly improved.

The organosilicon compound layer 4 according to the embodiment of the present invention may be formed in a yarn state. The bristle 2 is cut in the yarn to an appropriate size and planted in the body of the toothbrush 1. Specifically, the toothbrush 1 has a plurality of bristles 2 planted by cutting the yarn having the organosilicon compound layer 4 formed to a desired length. The liquid toothpaste layer 3 is applied on the organosilicon compound layer 4. The method of applying the liquid toothpaste layer 3 is not necessarily limited thereto, but may use dipping, spraying, or the like.

As mentioned above, although the present invention has been described in detail with reference to preferred embodiments, the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. It is possible.
