Embodiment 1

[0031] The preparation process of the modified silver oxide oxide oxide in this example is as follows:

[0032] Step S1, 5 parts of silver is loaded on 15 parts of oxide oxide, and the step of obtaining silver oxide oxide is obtained. The operation of this step is the same as the existing nano-silver loaded on the oxide oxide.

[0033] Step S2, completely dissolve the maleic anhydride to obtain a maleic anhydride-DMF solution in a DMF solvent, and then continuing to add maleic anhydride in the maleic anhydride-DMF solution, stirring, stirring all components Dissolve.

[0034] In this step, the ratio of the number of massage of maleic anhydride to the oxide oxide is 1-3, further preferably 1.5.

[0035] In step S3, in the solution of the silver oxide oxide, a solution of step S2, at 40 ° C to 50 ° C for 5-6 h, after the reaction is completed, and the filtration treatment is performed, and the calculkous oxide oxide is separated. Filter residue.

[0036] In step S4, the modified sil...

Abstract

The invention relates to a method for preparing an antibacterial agent with high antibacterial activity and anti-yellowing. The antibacterial agent for door and cabinet plates is modified silver-loaded graphene oxide modified by maleic anhydride, or / and made of graphite oxide Nano-silver-metal oxide is loaded with nano-silver-metal oxide to form composite antibacterial agent, and the modified composite antibacterial agent that forms through maleic anhydride modification comprises the steps: step 1, maleic anhydride is dissolved in DMF solvent completely, then continue Add xylene and stir to dissolve all components; step 2, add silver-loaded graphene oxide or / and composite antibacterial agent to the solution in step 1, and react at 40°C-50°C for 5-6h under stirring conditions, Then suction filtration treatment to obtain the antibacterial agent filter residue; step 3, the filter residue is fully washed, and then placed in an oven at 86°C-90°C to dry, to obtain modified silver-loaded graphene oxide modified by maleic anhydride or / and Modified compound antibacterial agent.

Description

Technical field [0001] The present invention relates to the field of functional plastic, and more particularly to an antibacterial plastic with a door cabinet using the antibacterial plastic. Background technique [0002] As the application ranges from the door cabinet, the plastic door cabinet has also raised. However, there is no antibacterial function in the current plastic door cabinet. With the continuous pursuit of life quality and health management, the antibacterial demand of the door cabinet also increases. For example, the door cabinets used in the food factory, medical laboratory, hospitals, kindergartens, have a growing demand for the antibacterial properties of the door cabinet. In order to increase the antibacterial properties of the door cabinet, one means to apply antibacterial coatings directly on the original door cabinet, but the antibacterial coating will change the style or tone of the original door cabinet, and the second antibacterial capacity will not last...
