Embodiment 1

[0054] Embodiment 1, be used for the preparation of the antibacterial coating agent of substrate surface treatment and antibacterial substrate

[0055] A zeolite inorganic antibacterial agent containing silver ions was added to a natural coating agent based on urushiol solution to prepare a coating agent for substrate surface treatment. For this, urushiol (HanKook National Co., Ltd.) was diluted to 1 / 30 in ethanol to prepare a coating solution, to which zeolite containing silver ions (Zeomic product supplied by IlKwang Polymer) was added and dispersed. Zeolite containing silver ions was added to the coating solution at a ratio of 0.3% w / v. After the Miracloth nonwoven fabric substrate (Sigma-Aldrich) was immersed in the prepared coating agent for 30 minutes, it was subjected to high-temperature polymerization at 140° C. and dried to introduce the coating agent on the surface of the substrate.

Embodiment 2

[0056] Embodiment 2, be used for the preparation of the antibacterial coating agent of substrate surface treatment and antibacterial substrate

[0057] A coating agent was prepared in the same manner as in Example 1 except that a 1 / 5 diluted urushiol solution was used, and then the coating agent was introduced onto the surface of the substrate.

Embodiment 3

[0058] Embodiment 3, be used for the preparation of the antibacterial coating agent of substrate surface treatment and antibacterial substrate

[0059] A coating agent was prepared in the same manner as in Example 1 except that a 1 / 100 diluted urushiol solution was used, and then the coating agent was introduced onto the surface of the substrate.
