In general, as society diversifies 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 as companion animals is increasing.

In the case of a family raising a companion animal, go out with the companion animal on a sunny day or to relieve the stress that the companion animal will receive from being in a confined space (house).

However, when you come back after going out, most of the cases require a bath in the indoor bathroom to treat simple foreign substances on the feet of your pet, so sometimes you refrain from going out because of this, or set a bath day to go out. Sometimes.

In this way, conventionally, there is no product that sterilizes and cleans the foreign substances on the companion animal's feet immediately on the spot, so if the companion animal goes outside and then comes indoors, it must be moved from the room to the bathroom of the companion animal to wash its feet or bathe it. There were annoying and cumbersome things to do.

For cleaning the house, it is good to spray water while wiping. In the case of small dogs, the dog owner can hold the pet and go to the bathroom to wipe it, but in the case of large dogs, it is difficult to hold and enter the bathroom.

So, it is good to use a faucet installed in the yard or garden to wipe one's feet outside the building's entrance and bring them into the house, but this is not easy.

This is because you have to hold the pet trying to move with one hand and use the other hand to spray water and shampoo, scrub, and brush.

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 entering the field or house.

When forming the coating layer, when the viscosity is less than a certain amount, flow occurs on the surface of the second housing unit 200, and it is difficult to form a uniform coating layer after the curing process in many cases. Accordingly, a problem of lowering the production yield may occur. In addition, even when the viscosity is too high, it is difficult to uniformly apply the composition and it is impossible 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 compositions of TX1 to TX5, the result of measuring the contact angle was confirmed. TX1 and TX5 measured receding contact angles less than 10 degrees. That is, it was confirmed that a phenomenon in which water droplets are pinned occurs when the coating composition is out of the optimal range for preparing the coating composition. On the other hand, it was confirmed that the pinning phenomenon did not occur in TX2 to 4, indicating that an excellent waterproof effect could be exhibited.

3. Fouling resistance evaluation

The second housing part 200 having the coating layer according to the above embodiment formed on the outside of the facility was attached to the model camera, and exposed to the general road driving environment for 4 days. As a comparative example (Con), the same second housing part 200 without a coating layer was used, and a model camera was attached to the same position of the vehicle in each embodiment.

After that, the degree of contamination of the second housing part 200 before and after the experiment was evaluated as related, and for objective comparison, compared with the comparative example in which the coating layer was not formed, the result was evaluated by an index of 1 to 10, and Table 4 below shown in In the index below, 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 part 200, even if the second housing part 200 is exposed to the outside while installing a lidar sensor or camera outside the vehicle, high contamination resistance can be obtained for a long time. 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 confirmed that the contamination resistance by the coating layer is very excellent.
