[0005] Zeolite antibacterial agent introduces silver ions through ion exchange to achieve antibacterial effect. However, the activity of zeolite silver-loaded antibacterial agent at high temperature is poor. In actual use, silver ions in the zeolite system are easily oxidized and discolored. thereby affecting the antibacterial effect

Abstract
The invention discloses a hard antibacterial pharmaceutical PVC (polyvinyl chloride) sheet and a production method thereof. The hard antibacterial pharmaceutical PVC sheet comprises, by weight, 800-1200 parts of polyvinyl chloride resin, 20-50 parts of plasticizer, 10-30 parts of stabilizer, 20-40 parts of antibacterial agent, 100-300 parts of glass fibers, 5-15 parts of inorganic nanofiller, 1-5 parts of pigment and 10-20 parts of antibacterial agent stabilizer. The hard antibacterial pharmaceutical PVC sheet and the production method thereof have the advantages that by the aid of the added antibacterial agent, a dustbin can achieve good antibacterial effect to inhibit bacterium growth, so that public health can be protected, and harm of bacteria on the dustbin to human bodies can be reduced; meanwhile, since the antibacterial agent is poor in stability during modification, in a process that the antibacterial agent is added, the antibacterial agent stabilizer also needs to be added to improve stability of the antibacterial agent during modification.
Description
technical field [0001] The present invention relates to the medicinal use of production, more specifically, it relates to a kind of antibacterial medicinal PVC hard sheet and its production method. Background technique [0002] Hard sheet, also known as film, is a sheet for blisters. Among them, the thickness greater than 2mm is called sheet. Commonly used are: PET (polyethylene terephthalate) hard sheet, PVC (polyvinyl chloride) hard sheet, PS (polystyrene) hard sheet, ABS (engineering plastic). [0003] It is widely used in pharmaceutical packaging. In the current market, PVC materials are mostly used to produce pharmaceutical hard tablets. The use in medicine has certain requirements for its antibacterial ability. [0004] At present, the Chinese patent with the application number CN201110450571.1 on the market discloses an antibacterial color masterbatch, which is formed by mixing components A, B, C, D, and E. The component A is a coloring agent, and its weight percent...
