Abstract

The invention discloses a heat dispersing material for a computer display and a preparation method thereof. The heat dispersing material for a computer display is composed of a matrix and a reinforcement. The matrix contains, by weight, 35-45 parts of ceramic powder and 15-25 parts of acylated cellulose. The reinforcement contains, by weight, 5-10 parts of polyethylene terephthalate, 5-10 parts of mica powder, 2-8 parts of gypsum powder, 4-8 parts of silicon carbide particles, 5-8 parts of stearic acid and 2-6 parts of glycerol. By optimizing the heat dispersing material for a computer display, thermal conductivity, waterproofness and flame retardant property of the heat dispersing material for a computer display are significantly enhanced. Thermal conductivity of the heat dispersing material for a computer display is 7.8-10.5 W / m.K, and the material is watertight at 0.1 MPa after more than 60 min. Limit oxygen index is 28.5% and above.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a heat dissipation material for a computer display and a preparation method thereof. Background technique [0002] With the popularity of high-performance computers, higher-resolution displays have higher and higher requirements for energy consumption. High-power displays can only convert about 15% of the input power into light energy, while the remaining 85% is converted into heat energy. Poor heat dissipation will lead to accelerated aging of the chips in the display and reduce the service life of the display. Therefore, how to prepare heat-dissipating materials for computer displays, while reducing its process cost and improving thermal conductivity, waterproof and flame-retardant performance, has always been a technical problem for the popularization and application of heat-dissipating materials for computer displays.
