Hard antibacterial pharmaceutical PVC (polyvinyl chloride) sheet and production method thereof

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...

Problems solved by technology

[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
