Warm-keeping board having antistatic function

Abstract

The invention relates to a warm-keeping board, and particularly relates to a warm-keeping board having an antistatic function. The warm-keeping board comprises a temperature-regulating composite layer and a warm-keeping layer, wherein the temperature-regulating composite layer contains silicon wrapped ferroferric oxide powder. Compared with the prior art, the warm-keeping board provided by the invention has the following advantages: the silicon wrapped ferroferric oxide powder is added in the temperature-regulating composite layer of the warm-keeping board prepared by the invention, so that charges are taken away on the surface, thereby preventing the charges from accumulating on the surface to form an electrostatic layer so as to achieve an antistatic effect; and meanwhile, the silicon wrapped ferroferric oxide powder can be favorably integrated with other materials, and a stable structure is formed outside the warm-keeping layer, so that the heat insulation property of the warm-keeping board is ensured, the warm-keeping effect is obviously improved, and the warm-keeping board is less prone to corrosion.

[0002] The thermal insulation board is generally composed of an outer thermal insulation layer composed of thermal insulation materials and an inner thermal control panel composed of phase change energy storage materials. However, the existing thermal insulation boards, although the outer thermal insulation layer can achieve a certain thermal insulation effect , but the heat insulation efficiency is not very ideal. During use, the use of the insulation board may be affected by the destruction of the internal medium. In practical applications, the insulation composite board usually has electrical, magnetic, and thermal requirements, especially There is more demand for insulation boards with anti-static functions. The fusion of existing electromagnetic shielding materials and composite boards is poor, which may affect the performance of the insulation board itself. Therefore, it is necessary to further improve the insulation boards with anti-static materials. Research
