Meanwhile, a coating composition for preventing corrosion may be applied to the pedal shaft 133 of the pedal driving unit 120 of the image expansion system for the virtual reality bicycle simulation system according to the second embodiment of the present invention. .

The coating composition is hexamethylated-100% by weight of the water-soluble resin composition prepared by mixing 80% by weight of Resorcinol diglycidyl ether and 20% by weight of propanol amine. Hexamethylated-hexamethylol melamine is composed of 1 to 10% by weight.

In the present invention, more environmentally friendly pedal drive unit 120 by utilizing properties such as excellent chemical resistance, dimensional stability of resorcinol diglycityl ether, corrosion resistance of propanolamine, and excellent lubrication characteristics of melamine derivatives, etc. A coating for preventing corrosion of the pedal shaft 133 may be formed.

The method for applying the coating composition for preventing corrosion is not particularly limited, but is preferably applied to the surface of the aluminum alloy so that the dry coating thickness is 10 to 30 μm. If the dry coating thickness is less than 10㎛ may shorten the life, if it exceeds 30㎛ there is no functional problem but the economic advantage is reduced.

In addition, the pedal shaft 133 of the pedal drive unit 120 to which the anti-corrosion coating composition is applied is cured for 10 to 50 minutes at 100 to 200 ℃, preferably 150 to 180 ℃ after air drying for 10 to 30 minutes It is possible to obtain a coating film which is non-tacky and excellent in gloss.

The alumina powder is added for the purpose of sintering, tangling, fusion prevention, etc. when heated to a high temperature. When the alumina powder is added in less than 60% by weight, the effect of sintering, tangling and fusion prevention is inferior, and when the alumina powder exceeds 60% by weight, the above-mentioned effect is not further improved, while the material cost is greatly increased. Therefore, it is preferable to add 60 weight% of alumina powders.

The NH ₄ Cl reacts with the aluminum, zinc, stocks, copper and magnesium in the vapor state to serve to activate diffusion and penetration. This NH ₄ Cl is added 30% by weight. If NH ₄ Cl is added at less than 30% by weight, it does not react properly with vaporized aluminum, zinc, stock copper and magnesium and thus does not activate diffusion and penetration. On the other hand, when NH ₄ Cl exceeds 30% by weight, the above-mentioned effect is not improved further, while the material cost is greatly increased. Therefore, it is preferable to add 30% by weight of NH ₄ Cl.

The zinc is formulated to prevent corrosion of metals in water and to be used for electrical applications. This zinc is mixed 2.5% by weight. If the mixing ratio of zinc exceeds 2.5% by weight, it will not properly prevent corrosion of the metal on water.

Therefore, the copper is preferably mixed 2.5% by weight.

Since the pure metal of magnesium has a low structural strength, the magnesium is combined with zinc to increase the hardness, tensile strength and corrosion resistance of the metal. This magnesium is mixed 2.5% by weight. If the mixing ratio of magnesium is less than 2.5% by weight, the hardness, tensile strength and corrosion resistance to salt water of the metal when combined with zinc and the like are not significantly improved. On the other hand, when the mixing ratio of magnesium exceeds 2.5% by weight, the above-mentioned effect is not improved further, while the material cost is greatly increased. Therefore, magnesium is preferably mixed at 2.5% by weight.

The titanium is a light, hard and corrosion-resistant transition metal element has a silver-white metallic luster, and because of its excellent corrosion resistance and low specific gravity, the weight of the titanium is only 60% compared to steel, so that the weight of the coating material applied to the metal base material is reduced but the gloss is increased. It is formulated to have excellent waterproof and corrosion resistance.

This titanium is mixed 2.5% by weight. When 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 much reduced, and the glossiness, waterproofness, and corrosion resistance are not greatly improved. On the other hand, if the mixing ratio of titanium exceeds 2.5% by weight, the above-mentioned effect is not further improved while the material cost is greatly increased. Therefore, the titanium is preferably mixed 2.5% by weight.

In addition, sodium carbonate or calcium carbonate may be used as a material for improving the applicability of the coating layer, but preferably sodium carbonate may be used. The boric acid and sodium carbonate is preferably 1: 0.01 to 1: 2 as the molar ratio. If the molar ratio is out of the above range, there is a problem in that the coating property of the substrate is lowered or the moisture absorption of the surface is increased after application, thereby removing the coating film.

The boric acid and sodium carbonate is preferably 1 to 10% by weight of the total composition aqueous solution, if less than 1% by weight has a problem that the coating property of the substrate is lowered, if it exceeds 10% by weight crystallization due to an increase in the thickness of the coating film Easy to occur
