Abstract

The invention provides an infrared radiation material, a preparation method thereof and an infrared emission base material. The infrared radiation material is prepared from, by weight, 2-9% of copper,0.3-6% of magnesium, 0.1-3% of rare earth, and the balance aluminum. The invention further provides the infrared emission base material made from the infrared radiation material, and the emission face of the infrared emission base material is provided with a protective film and micro holes. According to the novel infrared radiation material, the material has the low thermal resistance and high thermal conductivity, the raw material composition can be controlled as needed to obtain the good anti-oxidant performance and hardness, the deformation rate is low under high temperature, the materialcan be widely applied to preparing base materials of application materials in the multiple fields of industry, agricultural production, medical care, people's livelihood, military science and the like. An infrared emission device made from the material is high in thermal conversion rate, good in surface uniformity, and capable of increasing the transmission rate of infrared emission and the permeation action rate for the human body.

Description

technical field [0001] The invention relates to an infrared radiation material, a preparation method thereof and an infrared emission base material, belonging to the technical field of infrared material preparation. Background technique [0002] Up to now, in the international scope, ceramic materials are still mainly used as the infrared emission medium, making various coating materials or radiation devices. [0003] The heating tube made of ceramic material has problems such as low heat conversion efficiency, poor surface uniformity, and unsatisfactory permeability, especially the ceramic material is fragile. After the product is sold, the damage of the infrared radiation tube in the product will cause after-sales maintenance The cost is higher than the actual value of the product. [0004] In 1997, the inventor developed an infrared radiant tube made by coating the surface of the iron tube with enamel glaze prepared by infrared ceramic materials as a conversion medium fo...
