Abstract

The invention discloses a special antibacterial keyboard film for a notebook computer. The special antibacterial keyboard film is prepared from the following raw materials in parts by weight: 10 to 20parts of polymer polyol, 15 to 25 parts of polycarbonate, 13 to 24 parts of polyacrylate, 8 to 19 parts of diphenylmethane diisocyanate, 1 to 4 parts of polyimide resin, 4 to 9 parts of polyethyleneterephthalate, 2 to 6 parts of dioctyl phthalate, 2 to 5 parts of epoxy acrylate, 1 to 3 parts of calcium stearate, 3 to 6 parts of graphene oxide, 2 to 7 parts of nano titanium dioxide, 5 to 11 partsof modified nano-grade calcium carbonate, 1 to 2 parts of antibacterial agent, 2 to 3 parts of ultraviolet absorbent and 1 to 4 parts of anti-ageing agent. The special antibacterial keyboard film forthe notebook computer has good heat dissipation performance and has an antibacterial effect; meanwhile, the special antibacterial keyboard film has good stability and excellent water resistance and contractibility.

Description

technical field [0001] The invention belongs to the technical field of computer hardware, and in particular relates to a special antibacterial keyboard membrane for notebooks and a preparation method thereof. Background technique [0002] The keyboard is the most commonly used and most important input device, through which English letters, numbers, punctuation marks, etc. can be input into the computer, so as to issue commands and input data to the computer. [0003] Due to the frequent use of computers, some users often let the keyboard wear off those letters because of long-time typing, and the keyboard will also turn yellow. The above-mentioned problems of the laptop keyboard are even more serious. Although the current keyboard protective film can block dust, it also affects the heat dissipation of the keyboard, and has poor stability, poor water resistance and shrinkage. Contents of the invention [0004] The present invention provides a special antibacterial keyboard...
