Abstract

The invention discloses an antifouling and radiating keyboard film. The film is prepared from the following raw materials in parts by weight: 20-40 parts of polyacrylamide, 8-17 parts of carboxyl nitrile rubber latex, 13-19 parts of polycarbonate, 10-15 parts of epoxy resin, 6-12 parts of toluene diisocyanate, 4-8 parts of a graphene oxide aqueous solution, 2-6 parts of potassium chloride, 2-5 parts of stearic acid, 7-14 parts of modified montmorillonite, 2-3 parts of nano titanium dioxide, 3-8 parts of a plasticizer, 1-3 parts of an antibacterial agent, 1-2 parts of an antiager, 1.1-2.2 partsof luminous powder and 1-4 parts of a light stabilizer. The antifouling and radiating keyboard film inherits waterproofing and high permeability of the existing keyboard film, has better radiating effect and sterilization capability, provides guarantee for normal operation of a computer and safety guarantee for a computer user, and has better use value. Besides, a preparation method is simple andfeasible, and is suitable for industrial popularization and production.

Description

technical field [0001] The invention belongs to the technical field of keyboard protective films, and in particular relates to an antifouling and heat-dissipating keyboard film and a preparation method thereof. Background technique [0002] The transparent keyboard film in the traditional sense matches the keys of the keyboard, and the concave and convex keys are perfectly integrated, and has the protection functions of high transparency, waterproof and dustproof. And some colorful keyboard membranes, but most of the existing keyboard membranes are only modified for waterproof and high-permeability functions, and there is no research on the heat dissipation function of the computer, especially the keyboard has a certain hindering effect on the heat dissipation of the notebook computer, which is easy to produce Abnormal use of laptops caused by heat dissipation difficulties. Contents of the invention [0003] The present invention provides an anti-fouling and heat-dissipat...
