The metal copper film layer mainly contributes to golden yellow color, and the low-radiation effect of shielding infrared heat radiation is mainly the effect of the metal silver film layer and the metal copper film layer. The utility model discloses can be fast, make all outdoor fabrics on a large scale have shielding infrared thermal radiation function, reach better thermal-insulated cold-proof effect. And the magnetron sputtering vacuum has no problems of chemical addition, water pollution or air pollution, and is an environment-friendly production mode.
Description
Technical Field
The utility model belongs to innovation fabrics field is golden outdoor fabrics of shielding infrared thermal radiation.
Background
Under the continuous irradiation of sunlight, objects accumulate a large amount of heat, particularly in hot summer, so that the internal temperature of the objects is increased, and inconvenience and harm are brought to production and life of people. With the improvement of living standard of people, outdoor activities are more and more popular, the existing outdoor textile does not have good blocking effect on infrared radiation accounting for 46% of solar energy in sunlight, and in order to reduce troubles brought to production and living of people by high-temperature environment, the outdoor textile with the infrared reflection function is needed. The film layer capable of reflecting infrared rays is deposited on the surface of the outdoor textile in a vacuum mode, infrared radiation emitted by the sun can be blocked in a hot environment, and meanwhile, the infrared radiation loss of the covering in the outdoor textile can be reduced in cold winter, so that the requirements for heat insulation and heat preservation are met. The outdoor textile becomes a new heat insulation solution which can be widely applied.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a golden outdoor fabrics of shielding infrared radiation makes outdoor fabrics can have stronger barrier property to infrared radiation, can the separation outside infrared radiation get into outdoor fabrics in, reduces the loss of the inside temperature of cover simultaneously, reaches better thermal-insulated cold-proof effect. The film layer that reflects infrared heat radiation contains at least one metal layer with good electrical conductivity, such as a silver layer. And a layer of metal copper is added into the film layer in order to make the appearance color of the film appear golden yellow.
The utility model discloses a golden yellow shielding infrared radiation's outdoor fabrics solves through following technical scheme:
the golden outdoor textile for shielding infrared radiation has a surface film layer formed by depositing different metals or metal oxides or nitrides on the surface of the textile according to a certain sequence by a magnetron sputtering vacuum deposition method.
The composite film layer comprises three metal film layers, namely a copper film layer, a silver film layer and a nickel-chromium alloy film layer. Wherein the golden appearance color contribution is mainly from the metal copper film layer; because metal copper and metal silver have better electric conductivity, so can realize the higher reflection to infrared radiation, realize the low radiation function of shielding infrared thermal radiation.
A dielectric film layer is arranged between the outdoor textile substrate and the bottom metal film layer, and the materials of the dielectric film layer comprise titanium oxide, zinc oxide, tin oxide, silicon oxide and silicon nitride. A protective film layer is also arranged on the top metal film layer, and materials used by the protective film layer comprise materials with compact structures and higher hardness, such as titanium oxide, silicon nitride and the like, so as to protect the whole film layer.
The magnetron sputtering vacuum deposition comprises the step of depositing a dielectric film layer, a metal silver film layer, a metal copper film layer, a metal nickel-chromium film layer and a top protective film layer by layer. Wherein the thickness of the dielectric film layer is 1-70 nm, the thickness of the metal film layer is 0.1-100 nm, and the thickness of the protective film layer is 15-140 nm.
As a specific implementation mode, the structure of the composite film layer is Si3N4/Ag/Cu/NiCr/Si3N4The thickness of each film layer is 23nm/12nm/10nm/3nm/109 nm.
As another specific embodiment, the structure of the composite film layer is Si3N4/Ag/Cu/NiCr/Si3N4The thickness of each film layer is 15nm/4nm/8nm/5nm/114 nm.
As another specific embodiment, the structure of the composite film layer is Si3N4/Ag/Cu/NiCr/Si3N4The thickness of each film layer is 21nm/14nm/9nm/5nm/102 nm.
