An anti-corrosion layer may be applied to prevent development.

The coating material of the anti-corrosion layer is composed of 15% by weight of triethanolamine, 25% by weight of indiasol, 20% by weight of hafnium, 10% by weight of molybdenum emulsion (MoS2), 15% by weight of titanium oxide (TiO2), and 15% by weight of propionamide , Coating thickness can be formed to 8㎛.

Triethanolamine, indiazole, and propionamide serve to prevent corrosion and discoloration.

Hafnium is a transition metal element with corrosion resistance, and serves to have excellent water resistance and corrosion resistance.

Molybdenum emulsifier plays a role in imparting slidability and lubricity to the surface of the coating film.

Titanium oxide is added for the purpose of fire resistance and chemical stability.

The reason for the numerical limitation of the ratio of the components and the coating thickness as described above, as a result of analyzing the results through the test results while the inventor repeatedly failed several times, exhibited the optimum corrosion prevention effect at the ratio.

On the other hand, the anti-fouling coating layer made of a composition for anti-fouling coating to effectively achieve the prevention and removal of contaminants on the surface of the support bar stop 140 of a length-adjustable dog according to an embodiment of the present invention It can be applied.

The coco amphodiacetate and the alkyl glycol ether are preferably 1:0.01 to 1:2 as the molar ratio, and when the molar ratio is outside the above range, the applicability on the support bar stopper 140 of the dog's head decreases or the moisture on the surface after application. There is a problem that the coating film is removed due to increased adsorption.

The coco amphodiacetate and alkyl glycol ether are preferably 1 to 10% by weight in the total composition aqueous solution, and if it is less than 1% by weight, there is a problem in that the applicability on the support bar stopper 140 of the dog's head decreases, and 10% by weight If exceeded, crystal precipitation is likely to occur due to an increase in the thickness of the coating film.

On the other hand, as a method of applying the composition for preventing contamination on the support bar stopper 140, it is preferable to apply by a spray method. In addition, the final coating film thickness on the support bar stopper 140 is preferably 550 ~ 2000Å, more preferably 1100 ~ 1900Å. If the thickness of the coating film is less than 550 이, there is a problem that deterioration occurs in the case of high temperature heat treatment, and if it exceeds 2000 Å, there is a disadvantage that crystal precipitation on the coated surface is likely to occur.

In addition, the present composition for preventing contamination can be prepared by adding 0.1 mol of cocoamphodiacetate and 0.05 mol of alkyl glycol ether to 1000 mL of distilled water, followed by stirring.

In addition, the circumference of the dog body 110 may be coated with a fragrance material mixed with a functional oil to help sterilization and stress relief.

The mixing ratio of the fragrance material and the functional oil is 95 to 97% by weight of the fragrance material, and 3 to 5% by weight of the functional oil is mixed, and the functional oil is 50% by weight of Conifer note oil and Wormwood oil. oil) 50% by weight.

Here, the functional oil is preferably mixed with 3 to 5% by weight relative to the fragrance material. If the mixing ratio of the functional oil is less than 3% by weight, the effect is negligible. If the mixing ratio of the functional oil exceeds 5% by weight, the effect is not significantly improved, while the manufacturing cost is greatly increased.

Conifer note oil has good effects on neuralgia, muscle pain, anti-depression, and stress relief.

Wormwood oil is excellent in detoxification, skin disease treatment, sterilization, itching relief, clearing hair, and relaxing tension.

Therefore, as the fragrance material mixed with the functional oil is coated on the bald body 110, it is possible to obtain an effect such as sterilizing the bald body 110 and reducing the fatigue of workers.

The reason for limiting the constituent components and limiting the mixing ratio values for the fragrance substances and the functional oils is that the present inventors repeatedly failed through several times and analyzed through the test results, the optimum effect in the constituent components and the numerical limitation ratios It was shown.
