Nanometer multifunctional composite paint

Abstract

The invention provides nanometer multifunctional composite paint. The paint is mainly prepared by mixing composite nanometer powder, a dispersant, a coupling agent, a solvent, thermal conducting powder, and common paint; the composite nanometer powder, the dispersant, the coupling agent, the solvent, and the thermal conducting powder are premixed into composite nanometer powder syrup, and then a mechanical method is used for mixing the syrup and the common paint. The multifunctional composite paint has a heat energy-far infrared transforming function, when the composite nanometer powder slurry and the common paint are uniformly mixed, paint with heat radiation is manufactured; when the mixed paint is brushed on housings of illuminating lamps and electronic instruments, and the brushed paint is dried, the coating has the heat energy-far infrared transforming function, heat on the surfaces of the illuminating lamps and electronic instruments is transformed to far infrared ray and radiated to the air, in order to realize the purposes for reducing temperature of surfaces of illuminating lamps and electronic instruments.

Problems solved by technology

[0002] At present, lighting lamps and electronic instruments are constantly being miniaturized, especially mobile digital products have more urgent requirements for miniaturization of appearance. This will inevitably cause the heat generated by the electronic equipment to be more concentrated, but the appearance size of the electronic equipment is shrinking, which will easily make the working temperature of the internal components of the electronic equipment exceed the rated value. If the electronic components are in a relatively high temperature environment for a long time, The working life of electronic instruments will be reduced exponentially; lighting fixtures are developing towards LEDs, which are industries that are prioritized by the state for development. The luminous efficiency of LED lights is currently only 18-20% of the input power, 80-80% of the input power. 82% is converted into heat, and the heat must be diffused into the air through the substrate and shell connected to the LED. At present, there are no relatively mature products in terms of LED heat dissipation and printed circuit board heat dissipation technology. The heat dissipation technology of LED lights directly restricts large The large-scale promotion of high-power LED lamps. At present, the heat dissipation of electronic instruments usually relies on axial flow fans. The heat dissipation of LED lamps relies on anodized or blackened shell surfaces. The above two heat dissipation methods are not enough to solve lighting problems well. The problem of heat dissipation of lamps and electronic instruments has inhibited the rapid development of high-power LED lamps and the development trend of miniaturization and thinning of electronic instruments

[0003] In terms of printing inks, traditional solvent-based inks pollute the environment and are being phased out. Ultraviolet photosensitive inks are environmentally friendly inks, and their usage has been increasing at an annual rate of 20-25% in recent years. Adding photosensitizers, various photosensitizers can only be excited under specific ultraviolet wavelength conditions, and play a role in curing photosensitive inks. The amount of photosensitizers added accounts for about 20% of the ink weight, and the price of photosensitizers is relatively high. It is about 1,000 yuan per kilogram. The above factors make the production cost of photosensitive ink relatively high, and the curing conditions are relatively harsh, which limits the wide use of ultraviolet photosensitive ink.
