In general, as society becomes diversified and families become nuclear families, interest in companion animals such as dogs, cats, and monkeys is increasing, and the tendency to live in the same residential space with companion animals is increasing.

In the case of a family with a companion animal, go out with the companion animal to relieve the stress of being only in the confined space (home) or on a sunny day.

However, when returning from going out, it is often necessary to take a bath in the indoor bathroom even for simple foreign substances on the pet's feet. In some cases.

As such, conventionally, there is no product that directly sterilizes and cleans foreign substances on the feet of companion animals on the spot. There was a cumbersome and cumbersome thing to do.

To keep the house clean, it is good to wipe it while spraying it. In the case of a small dog, the owner can take the pet to the bathroom and wipe it, but in the case of a large dog, it is difficult to take it to the bath.

Therefore, it is good to use a faucet installed in the yard or garden to wipe your feet outside the entrance of the building and then enter the house, but this is not easy.

This is because you have to hold the pet that is about to move with one hand, and spray water and shampoo with the other hand, rub it, and brush it.

These daily tasks are time-consuming and energy-consuming.

Therefore, there is a need for an invention that can easily wash and dry foreign substances on the feet of companion animals before they enter the field or house.

TX1 TX2 TX3 TX4 TX5 sensory evaluation × ○ ○ ○ ×

When the coating layer is formed, when the viscosity is less than a certain level, a flow occurs on the surface of the second housing part 200, so that it is difficult to form a uniform coating layer after the curing process. Accordingly, there may be a problem in that the production yield is lowered. In addition, even when the viscosity is too high, it is difficult to uniformly apply the composition to form a uniform coating layer.

2. Measurement of water repellency angle

After forming the coating layer on the surface of the second housing part 200, the results of measuring the water repellency angle are shown in Table 3 below.

As shown in Table 3, after forming the coating layer using the coating composition of TX1 to TX5, the result of measuring the contact angle was confirmed. For TX1 and TX5, the receding contact angle was measured to be less than 10 degrees. That is, when it is out of the optimal range for preparing the coating composition, it was confirmed that a phenomenon in which water droplets are pinning occurs. On the other hand, it was confirmed that the peening phenomenon did not occur in TX2 to 4, thereby exhibiting an excellent waterproof effect.

3. Pollution resistance evaluation

The second housing part 200 having the coating layer formed according to the above embodiment on the outside of the facility was attached to the model camera, and exposed to the driving environment on a general road for 4 days. As the comparative example (Con), the same second housing part 200 on which the coating layer was not formed was used, and in each embodiment, the model camera was attached to the same position of the vehicle.

Then, the degree of contamination of the second housing part 200 before and after the experiment was evaluated as related, and for objective comparison, the result was evaluated as an index of 1 to 10 in comparison with the comparative example in which the coating layer was not formed, and the results were evaluated in Table 4 below. shown in In the following index, the lower the number, the better the stain resistance.

(Unit: Index)

Referring to Table 4, when the coating layer is formed on the second housing unit 200, the high contamination resistance is maintained for a long time even when the lidar sensor or camera is installed on the outside of the vehicle and the second housing unit 200 is exposed to the outside. It can be seen that image data can be collected in a form that is easy to analyze for a period. In particular, in the case of TX2 to TX4, it can be seen that the stain resistance by the coating layer is very excellent.
