Abstract

The invention discloses an antibacterial fluorescent keyboard protective film. The antibacterial fluorescent protective film is prepared from the following components in parts by weight: 30-65 parts of polymer polyol, 8-18 parts of a chain extender, 0.1-0.6 part of an antioxidant, 25-30 parts of toluene diisocynate, 0.3-0.5 part of a lubricant, 0.2-0.5 part of an antibacterial agent, 4-8 parts ofrare earth aluminate noctilucent powder and 0.1-0.4 part of a light stabilizer. The invention further discloses a preparation method of the protective film, and the antibacterial agent is added into the keyboard protective film, so that common harmful bacteria such as saccharomycetes, escherichia coli and staphylococcus aureus can be effectively inhibited when people touch a keyboard every day. Inaddition, the rare earth aluminate noctilucent powder is added into the keyboard film, so that the keyboard film has a good antistatic effect and does not lose a noctilucent function.

Description

technical field [0001] The invention belongs to the technical field of computer input equipment, and in particular relates to a keyboard antibacterial fluorescent protective film, and also relates to a preparation method of the protective film. Background technique [0002] The keyboard is a common computer input device, but because it is touched by hands every day, bacteria are easy to accumulate on the keyboard, and the keyboard protective film currently on the market is only made of simple silica gel, which cannot inhibit the growth of bacteria. At the same time, the existing keyboard Although the protective film contains fluorescent particles, it does not have antistatic properties. Therefore, there is an urgent need for an antibacterial fluorescent protective film that can inhibit bacterial growth and antistatic. Contents of the invention [0003] The purpose of the present invention is to provide a keyboard antibacterial fluorescent protective film, which solves the ...
