Multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric, preparation method and application

The invention relates to a preparation method and an application of multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric. The multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric is formed by successively arranging and laminating a metal foil reflection layer, a phase change temperature limitation layer, an interval composite membrane heat-insulation layer and a flame-retardant comfortable layer, wherein the metal foil reflection layer has high reflectivity and an enhanced heat-dissipation function; the phase change temperature limitation layer has functions of high energy consumption absorption and evenly-distributed heat conduction; the interval composite membrane heat-insulation layer has the functions of reflection insulation and even distribution of heat; and the flame-retardant comfortable layer has the functions of low-contact heat conduction, heat insulation and comfort. When the front side of the multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric is under the action of open fire and strong heat flow environment, the back side of the multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric can be kept below 50DEG C which is near the safe temperature state of the human skin, and the integral structural form and the mechanical property are stable. The natural thickness of the composite fabric is 5-15mm, the compression thickness of the composite fabric is 3-8mm, and the square meter quality of the composite fabric is 400-1500g/m<2>. The composite fabric is fire-proof heat-insulation material which is totally sealed, stuck and sewn and can be used for individual protection and environment heat insulation in special high-temperature occasions, such as fire control, military, exploration, safe escape and industry and the like.

Light reflecting thin film of photovoltaic module and method for fixing light reflecting thin film and soldering strip

The invention discloses a light reflecting thin film of a photovoltaic module and a method for fixing the light reflecting thin film and a soldering strip. The light reflecting thin film of the photovoltaic module comprises a base material, a micro-prism layer and a light reflecting layer. The thickness of the base material ranges from 10 micrometers to 1 millimeter, and the base material comprises plastic base material body and a paper base material body. The micro-prism layer is arranged on the upper surface of the base material, the thickness of the micro-prism layer ranges from 1 micrometer to 500 micrometers, and the micro-prism layer is made of plastic and is of a texture structure. The light reflecting layer is arranged on the upper surface of the micro-prism layer, the thickness of the light reflecting layer ranges from 1 micrometer to 500 micrometers, and the light reflecting layer is made of vacuum nickel plating films or vacuum aluminum plating films or vacuum silver plating films or polyester films coated by high-reflectivity silver or high-reflectivity multilayer dielectric films. The light reflecting thin film is simple in structure and low in cost, the output power of the assembly is increased, the application method of the light reflecting thin film is compatible with an existing photovoltaic module process, and therefore long-term reliability and the service life of the assembly can not be affected. The output power of the photovoltaic assembly can be increased by 1.5% to 3%, and the light reflecting thin film effectively reduces manufacturing cost of the unit power of the photovoltaic module.
