Abstract
The invention discloses a honeycomb-shaped (or ant nest shaped) composite which is prepared by resinoid bond of specially-treated yellow sand (the yellow sand is treated by removal of conductive impurities and resin coating), and a layer of glass fiber cloth is pasted for improving the strength; the composite is a multi hole material and is easy to be invaded by particles, fluids and gases, so that the composite is coated with an insulating protective film. The composite is good in insulativity, low in thermal resistance, and good in electromagnetic radiation and interference reduction effects, is not only conducive to environmental protection (electromagnetic wave polluted environment), but also is conducive to the operation safety of electrical equipment, can reduce the capacitive leakage current, and can reduce the noise transmission, so that the composite is especially suitable for electrothermal films, heating cables, and other electrothermal floor heating equipment.
Description
The present invention relates to a kind of high insulation, high heat conduction, intercept hertzian wave, reduce capacitive character leakage current and sound insulation function in one matrix material, it is that a kind of yellow sand with special processing (is removed conductive impurity, comprised water, and with polymer coating), form cellular (or it is cave-shaped to be called ant) advanced composite material through resinoid bond again, its tool function is along with this material thickness increases and increases, but thermal conductivity faint reduction thereupon; Cellular when manufacture (or it is cave-shaped to be called ant) is better, and functional effect is better, but intensity can decline to some extent.In order to improve the strength of materials of the present invention, therefore pasted layer of glass cloth, because it is a kind of multi-hole material, easily to be invaded by particulate, fluid, gas, one deck insulating protective film should be wrapped in using in historical facts or anecdotes border.
At present, relative with material function of the present invention what approach be silicon rubber and ceramic-like materials, but price is more expensive, and insulating heat-conductive is not as material of the present invention, therefore cannot improve thickness, reduces capacitive character and leaks electricity.It is lower that the present invention has high insulation, high heat conduction, material price simultaneously, can effectively intercept hertzian wave, reduces capacitive character leakage current, disease has certain sound insulation function.The present invention is applicable to reduce electromagenetic wave radiation and the interference of electric installation, improve insulation of electrical installation, reduce the electric leakage of electric installation capacitive character, especially be applicable to the insulating heat-conductive of resistor-type electric heating equipment, as: the floor heating of the forms such as household electric hotting mask and heating cable, the floor heating meeting of current Electric radiant Heating Film and heating cable form produces a large amount of hertzian wave to external irradiation and capacitive character electric leakage, human body (is especially worn the people of schrittmacher) in a large amount of electromagnetic environment, health is had a strong impact on, in the time that humid environment and the superincumbent insulated with material of covering are poor, can produce larger leakage current, not only affect safety, also can make earth leakage protective device action and indoor dead electricity (unless the few dress in surface or do not fill good electric leakage and draw guard, but indoor electric magnetic wave and danger are increased).
This material invention can effectively address the above problem.Accompanying drawing explanation: Fig. 1 to Fig. 3 is by this invention and makes local side photographic view sheet material, that cut protective membrane open.Fig. 1 be cut open protective membrane, sheet material local side photographic view.Fig. 2 cuts protective membrane, sheet material part, side open to amplify the photographic view of 3 times, to see tiny cellular (or it is cave-shaped to be called ant).Fig. 3 cuts protective membrane, sheet material part, side open to amplify the photographic view of 6 times, to see tiny cellular (or it is cave-shaped to be called ant) clearly.
Claims (1)
1. the yellow sand for insulating heat-conductive and polymer composites, it relates to yellow sand special processing (remove conductive impurity and use resin dressing), it comprises to form cellular (or it is cave-shaped to be called ant) through resinoid bond again: with tubing, sheet material and the wire rod etc. of this method and material produce different geometries, for following situations:
1) hertzian wave that reduces electric installation is to external irradiation.
2) reduce electric installation and be subject to Electromagnetic Interference.
3) reduce capacitive character leakage current.
4) insulation, heat conduction, sound insulation.
