Abstract

The invention discloses an antibacterial plastic for a keyboard, and belongs to the technical field of plastic products. The antibacterial plastic is prepared from, by weight, 100-120 parts of ABS (acrylonitrile butadiene styrene) matrix resins, 15-25 parts of polycarbonate, 2-10 parts of ethylene-acrylic acid copolymers, 1-5 parts of polyvinyl alcohol, 2-10 parts of ethylene-propylene-diene-terpolymer rubber, 4-8 parts of antibacterial master batches, 10-15 parts of fillers, 5-12 parts of dispersing agents, 0.2-0.6 part of antioxidant, 0.3-0.7 part of coupling agents, 0.2-0.6 part of stabilizers and 40-65 parts of compatilizers. The shell materials of the keyboard are provided with the antibacterial master batches, the broad-spectrum antibacterial property, the antibacterial slow-release property and weather resistance of the plastic are improved, and the mechanical property of the antibacterial plastic is improved.

Description

technical field [0001] The invention belongs to the technical field of plastic products, and in particular relates to an antibacterial plastic suitable for keyboards. Background technique [0002] With the development of informatization, computers are popularized rapidly. Market surveys have found that in some public places with a large flow of people, such as Internet cafes, libraries, hospitals, etc., computers, as a kind of public equipment, have a very high utilization rate, but the relevant units do not. Most of them lack effective cleaning and disinfection measures, and the user's awareness of hygiene prevention in this respect is also very weak. Therefore, computer (notebook) keyboards become a place to hide dirt and the source of bacterial infection. If the plastic with antibacterial function is used, the growth of bacteria on the surface of the remote control can be inhibited, and the harm of bacteria to the human body can be reduced. [0003] Bacteria includes bac...
