Abstract

The invention discloses a keyboard protective film, and belongs to the technical field of high polymer materials. The keyboard protective film is prepared through the following steps: successively weighing 35-45 parts of TPU, 3-5 parts of plasticizer, 2-4 parts of anti-aging agent, 8-12 parts of mixed extract liquid, 5-10 parts of mixed essential oil, 4-6 parts of modified glass fiber, 15-20 partsof polystyrene, 2-5 parts of ammonium sulfate, 5-8 parts of nanometer silver powder and 1-3 parts of dispersant according to weight parts, and performing smashing and then sieving on the ammonium sulfate to obtain ammonium sulfate powder; adding the TPU, plasticizer, anti-aging agent, mixed extract liquid, mixed essential oil, modified glass fiber, polystyrene, ammonium sulfate powder, nanometersilver powder and dispersant into a mixer, then adding water with a mass of 0.5-0.8 time to that of TPU into the mixer, and performing uniform stirring to obtain a mixture; and extruding the mixture in a twin-screw extruder to obtain a blank, and flow-casting the blank into a film to obtain the keyboard protective film. The keyboard protective film has an excellent antibacterial property, and at the same time has better mechanical properties.

Description

technical field [0001] The invention discloses a keyboard protective film, which belongs to the technical field of polymer materials. Background technique [0002] The keyboard membrane is made of TPU elastic material made of fashionable IT. The smooth feel of TPU and the bottom adsorption of silicone are high-end keyboard membranes that combine the advantages of two materials. TPU was more suitable as a material for the keyboard membrane in the early days, but it also has insurmountable shortcomings such as: relatively brittle and easy to be broken, poor fit and difficult to fix, etc. [0003] With the increasing improvement of information systems, medical institutions are promoting paperless in a wider field, and the coverage of computers is expanding day by day. Along with this, the problem of microbial contamination of computer keyboards and mice has attracted more and more attention. Some scholars have found that the average microbial contamination of each key of the ...
