Embodiment 1

[0007] First prepare the coating liquid, take carboxymethyl chitosan 22kg, copper powder 17kg, zinc powder 6kg, sodium stearate 15kg, adipic acid 5kg, urea-formaldehyde resin 21kg, ethylene glycol diacetate 11kg , mix and stir all the ingredients, and get the coating liquid after stirring. The coating liquid is then sprayed and covered on the surface of the steel plate, and after drying, the purified workshop plate containing the antibacterial coating is prepared.

Embodiment 2

[0009] The preparation method is the same as in Example 1, and the content of each component in the present embodiment is: 19kg of carboxymethyl chitosan, 14kg of copper powder, 5kg of zinc powder, 8kg of sodium stearate, 11kg of adipic acid, 16kg of urea-formaldehyde resin, Ethylene glycol diacetate is 17kg.

Embodiment 3

[0011] The preparation method is the same as in Example 1, and the content of each component in the present example is: 20kg of carboxymethyl chitosan, 15kg of copper powder, 6kg of zinc powder, 12kg of sodium stearate, 8kg of adipic acid, 18kg of urea-formaldehyde resin, Ethylene glycol diacetate is 14kg.

[0012] Antibacterial performance test

[0013] Get the product of embodiment 1, embodiment 2, embodiment 3 and carry out antibacterial experiment, antibacterial experiment selection standard is ASTM E2180, selects bacteria class to be Escherichia coli and Staphylococcus aureus. The experimental results show that the Escherichia coli inhibition rates of Example 1, Example 2, and Example 3 are 98%, 99%, and 99%, respectively. The inhibition rates of the staphylococcus aureus of embodiment 1, embodiment 2, embodiment 3 are respectively 95%, 97%, 96%.

Abstract

The invention relates to a clean workshop antibiosis sheet material, which employs cold rolling steel plate as inner layer and antibiosis coating as external layer, and the coating is composed of the following components by weight: 19-22 parts of carboxymethyl chitosan, 14-17 parts of copper powder, 5-6 parts of zinc powder, 8-15 parts of sodium stearate, 5-11 parts of adipic acid, 16-21 parts of urea-formaldehyde resin, 11-17 parts of ethylene acetate. The prepared clean workshop antibiosis sheet material has good antibiosis effect.

Description

technical field [0001] The invention relates to a purification workshop board, in particular to an antibacterial board for a purification workshop. Background technique [0002] The purification workshop has very high standards for the cleanliness of the workshop. If the total amount of bacterial colonies in the workshop exceeds the standard, it will have a certain impact on the products produced in the workshop and reduce the performance and quality of the products. At present, the plates used in the purification workshop on the market do not have antibacterial properties, so if there is a plate that can be used in the purification workshop and has good antibacterial properties, it will improve the cleanliness of the purification workshop. Contents of the invention [0003] The technical problem to be solved: the poor antibacterial performance of the plates used in the purification workshop. [0004] Technical solution: The invention discloses an antibacterial plate for ...
