Methods of preparing antiseptic antibacterial agents in comparative examples one to two reference the methods of preparing antiseptic antibacterial agents in examples three.
Use effect experiment:
(1) test data:
the epoxy resin powder coating prepared by the third embodiment of the invention is coated on food equipment, various performance tests are carried out on a coating film on the food equipment, the appearance of a paint film is mainly observed, the impact resistance of the paint film is tested, and the specific test results are shown in the table I:
table one: the epoxy resin powder coating prepared in the third embodiment of the invention has various performance test results.
(2) Paint film properties
The salt spray resistance and adhesion of the paint films of the powder coatings of examples one to three, and of comparative examples one to three, respectively, applied on food equipment, were tested with reference to the test standards for the paint films.
As can be seen by testing the salt spray resistance and the adhesive force of the paint film, the microcrystalline cellulose, the graphene and the antibacterial preservative have a synergistic effect, and when the microcrystalline cellulose, the graphene and the antibacterial preservative are used together, the salt spray resistance and the adhesive force of the paint film can be improved.
(3) Antibacterial and antiseptic properties
The test method comprises the following steps: referring to the national standard GB/T21866-2008 antibacterial coating (paint film) antibacterial performance measurement method and antibacterial effect, the coatings prepared in the third example and the first to the third example are made into a coating film according to the requirements of the national standard (general preparation method of GB/T1727 paint film), before the experiment, an ultraviolet sterilizing lamp and medical alcohol are adopted to sterilize the surface of the paint film, staphylococcus aureus and escherichia coli are respectively inoculated on the prepared paint film as detection strains, then the culture is carried out for 24 hours, then the cultured sample is taken out and repeatedly washed for multiple times, the washed washing liquid is inoculated in a culture medium and cultured for 24 hours, then viable count is carried out, when the antibacterial performance test of the paint film is carried out, the culture is carried out on a blank culture medium under the same condition as a control, and the specific detection results are shown in the following table:
as can be seen from the above table, the antiseptic antibacterial agent is added in the third example, so the antibacterial agent has excellent antibacterial performance, while the antiseptic antibacterial agent is not added in the first to third comparative examples, so the antibacterial effect is poor, and the antibacterial agent cannot be applied to places such as food equipment and the like with high requirements on the antiseptic effect. Meanwhile, the antiseptic antibacterial agent is added to achieve the bactericidal effect on bacteria or germs in the paint film, so that the corrosion of the bacteria or germs on the base material is weakened, and a better bactericidal effect is achieved.
In conclusion, the epoxy resin powder coating can be widely applied to food equipment or coating products with high requirements on sanitary corrosion resistance, and has excellent film forming property and antibacterial and anticorrosive properties. In addition, the antiseptic and antibacterial agent can inhibit the breeding of bacteria and expel insects, is safe and environment-friendly in the using process, does not release toxic and harmful substances after long-term use, and does not cause the toxic and harmful substances to permeate into food during food processing.
