High-heat-dissipation luminous keyboard membrane and preparation method thereof

Abstract

The invention discloses a high-heat-dissipation luminous keyboard membrane and a preparation method thereof. The high-heat-dissipation luminous keyboard membrane is prepared from the following components of polycarbonate, polyacrylate, luminous powder, graphene, modified attapulgite clay, nanometer titanium dioxide, magnetic component, anti-aging agent, antioxidant and flame retardant. The preparation method comprises the following steps: adding the polycarbonate and the polyacrylate into a reaction kettle, heating, melting, adding the graphene, mixing and reacting for 1 to 2 hours; adding the luminous powder, the anti-aging agent, the antioxidant and the flame retardant, stirring uniformly, and performing shearing dispersion; adding the modified attapulgite clay and the nanometer titanium dioxide, stirring uniformly, placing a mixture into an ultrasonic environment and holding for 10 to 20 minutes, adding the magnetic component, mixing uniformly, and placing a mixture into a membrane forming machine for membrane forming to obtain the keyboard membrane. The keyboard membrane has higher heat dissipation performance and higher luminous characteristic, so that a computer can be operated without turning on a light at night, and the energy consumption is lowered greatly; the high-heat-dissipation luminous keyboard membrane has better significance.

Description

technical field [0001] The invention relates to the computer office field, in particular to a high heat dissipation luminous keyboard film and a preparation method thereof. Background technique [0002] In today's era where information technology fills the living space, people increasingly feel how fast the evolution of consumer electronics is. More than 20 years ago, when personal computers entered the family, the influence of computers on people's lives was greater than that of other electronic products. In today's information age, people use computers more and more. Computer keyboards are undoubtedly the link between people and computers. The important way of contact, 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. To this end, some companies are committed to creating personalized, s...

More than 20 years ago, when personal computers entered the family, the impact of computers on people's lives was greater than that of other electronic products. In today's information age, people are using computers more and more. Computer keyboards are undoubtedly the link between people and computers. An important way of contact, due to the frequent use of computers, some users often let the keyboard wear off those letters due to long-term typing, and the keyboard will also turn yellow. The above-mentioned problems of laptop keyboards are even more serious

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 notebook computers caused by heat dissipation difficulties, and the existing keyboard membrane does not have luminous properties
