On the other hand, RD (Polymerized trimethyl dihydroquinoline) is added to the moving head 323 of the synthetic resin material to increase the oxidation resistance. This RD increases ozone resistance and oxidation resistance, and prevents corrosion and oxidation of the moving head 323.

In the present invention, when the sum of the synthetic resin and RD is 100 parts by weight, the RD preferably includes 0.4 to 1.2 parts by weight. This is because if the addition amount of RD is less than the above-mentioned range, it is difficult to obtain oxidation resistance, and if it exceeds the above-mentioned range, the density and firmness of the tissue are affected.

Since RD is further added to the moving head 323 of the synthetic resin material, the oxidation resistance of the present invention is greatly improved, thereby maximizing the service life of the product.

Meanwhile, the toothbrush of each of the above embodiments may be made of a synthetic resin material, or may be made of a metal material. The bristle head parts 120, 220 and 320 and the tongue cleaner parts 130, 230 and 330 may be made of an aluminum material. In this case, the handle parts 110, 210 and 310, The surfaces of the bristle head portions 120, 220, and 320 and the tongue cleaner portions 130, 230, and 330 are coated with the surface of the metal material to prevent corrosion of the surface from dust, A coating layer may be formed of a material. The coating layer is composed of 60 wt% of alumina powder, 30 wt% of NH ₄ Cl, 2.5 wt% of zinc, 2.5 wt% of copper, 2.5 wt% of magnesium and 2.5 wt% of titanium.

The alumina powder is added for the purpose of sintering, entangling, fusion prevention, etc. when heated to a high temperature. When such an alumina powder is added in an amount of less than 60% by weight, the effect of sintering, entangling and fusion prevention is deteriorated. When the alumina powder exceeds 60% by weight, the above effect is not further improved, but the material cost is greatly increased. Therefore, it is preferable to add 60 wt% of the alumina powder.

The NH ₄ Cl reacts with steam, aluminum, zinc, copper, and magnesium to activate diffusion and penetration. This NH ₄ Cl is added in an amount of 30% by weight. When NH ₄ Cl is added in an amount of less than 30% by weight, the reaction with aluminum, zinc, copper and magnesium in a vapor state is not properly performed, thereby failing to activate diffusion and penetration. On the other hand, if NH ₄ Cl exceeds 30 wt%, the above-mentioned effect is not further improved, but the material cost is greatly increased. Therefore, it is preferable to add 30 wt% of NH ₄ Cl.

The zinc is compounded to prevent corrosion of the metal that is in contact with water and to be used for electrical applications. 2.5% by weight of this zinc is mixed. If the mixing ratio of zinc exceeds 2.5% by weight, corrosion of the metal which is in contact with water can not be properly prevented. On the other hand, when the mixing ratio of zinc exceeds 2.5% by weight, the above-mentioned effect is not further improved, but the material cost is greatly increased. Therefore, it is preferable that zinc is mixed at 2.5% by weight.

The copper is combined with the aluminum to increase the hardness and tensile strength of the metal. This copper is mixed at 2.5% by weight. If the mixing ratio of copper is less than 2.5 wt%, the hardness and tensile strength of the metal can not be properly increased when combined with aluminum. On the other hand, when the mixing ratio of copper exceeds 2.5% by weight, the above-mentioned effect is not further improved, but the material cost is greatly increased. Therefore, copper is preferably mixed at 2.5% by weight.

Since the pure metal of magnesium has a low structural strength, it is used in combination with the zinc and the like to improve the hardness, tensile strength and corrosion resistance of the metal. This magnesium is mixed at 2.5% by weight. When the mixing ratio of magnesium is less than 2.5% by weight, the hardness, the tensile strength and the corrosion resistance to the salt water of the metal are not greatly improved when they are combined with zinc and the like. On the other hand, when the mixing ratio of magnesium exceeds 2.5% by weight, the above-mentioned effect is not further improved, but the material cost is greatly increased. Therefore, it is preferable that magnesium is mixed with 2.5% by weight.

The titanium is a lightweight, hard and corrosion resistant transition metal element with a silver-white metallic luster. Because it has excellent corrosion resistance and specific gravity, it weighs only 60% of steel. Therefore, the weight of the coating material applied to the metal base material is reduced, Excellent water resistance and corrosion resistance.

This titanium is mixed at 2.5% by weight. If the mixing ratio of titanium is less than 2.5% by weight, the weight of the coating material applied to the metal base material is not so reduced, and glossiness, water resistance and corrosion resistance are not greatly improved. On the other hand, when the mixing ratio of titanium exceeds 2.5% by weight, the above effect is not further improved, but the material cost is greatly increased. Therefore, titanium is preferably mixed at 2.5% by weight.

The application method of the application layer is as follows.

The base material in which the coating layer is to be formed and the coating material blended in the above composition are put in the closed furnace together with the argon gas being injected at a rate of 2 L / min in order to prevent oxidation of the base material inside the furnace. And maintained at a temperature of 700 ° C to 800 ° C for 4 to 5 hours.

Aluminum powder, alumina powder, zinc, copper, magnesium, and titanium compounds penetrate into the surface of the base material to form a coated layer, .

After the coating layer is formed, the inside temperature of the closed material is maintained at a temperature of 800 ° C. to 900 ° C. for 30 to 40 hours so that a coating layer for corrosion prevention is formed on the surface of the base material to isolate the surface of the base material from the outside air do. At this time, the abrupt temperature change in the above-mentioned process may cause the coating layer on the surface of the base material to peel off, so that the temperature is changed at a rate of 60 ° C / hr.

The coating layer of the present invention has the following advantages.

Since the application layer of the present invention has a very wide range of applications, it can be applied by various methods such as curtain coating, spray painting, dip coating, flooding and the like.

In addition to the principle protection against corrosion and / or scale, the application layer of the present invention can be applied with a very thin layer thickness in addition to improving electrical conductivity, as well as material and cost saving. A thin electrically conductive primer may be applied to the top of the application layer if high electrical conductivity is desired after the hot forming process.

After the molding process or the hot forming process, the coating material can be retained on the surface of the substrate, for example, to increase scratch resistance, to improve corrosion protection, to meet aesthetic appearance, to prevent discoloration, And may be provided as a primer for conventional downstream processes (e.g., impregnated and electro-mobile dip application).
