Preparation method for constant-temperature material

Abstract

The invention discloses a preparation method for a constant-temperature material. The preparation method for the constant-temperature material comprises the following steps: weighing stainless steel;taking graphene; preparing a carbon powder; adding rare-earth elements and metals; and obtaining the constant-temperature material through mixing, high-temperature smelting and crystallization. Because the main components of the constant-temperature material are composed of the graphene, the carbon powder, the rare-earth elements and a small amount of common metal elements, compared with a stainless steel kitchenware material, the constant-temperature material does not release heavy metal elements, have no standard-exceeding problem of heavy metals, is more green and environment-friendly, andachieves a higher guarantee on healthy diet; and according to the preparation method for the constant-temperature material, other auxiliary devices do not need to be added, and temperature control canbe realized through the own newest function of the material, and in particular, the preparation method for the constant-temperature material is more prominent in application advantage in the fields of non-stick pans and smokeless pans, also has great advantages in the aspects of material performance, product structure performance, effect popularization, product production cost and the like, and is of great use significance to the field with a requirement on a temperature, for example, the kitchenware industry or the small appliance industry.

Description

technical field [0001] The invention relates to the technical field of constant temperature materials, in particular to a preparation method of constant temperature materials. Background technique [0002] At present, conventional metal materials such as stainless steel, aluminum, and iron are often used in the kitchenware industry and small household appliance industry. Due to frequent physical contact, stainless steel materials are more widely used, mainly because stainless steel materials have ① Thin and dense chromium-rich oxidation on the surface of stainless steel Membrane, has good corrosion resistance, stainless steel has corrosion resistance, enhanced strength, steel deformation is not easy to break and environmental protection performance, not easy to rust, and has good ductility and toughness. It is suitable for use in harsh environments (wet, acid-base and other indoor and outdoor environments). ②Stainless steel can work safely under high temperature for a long t...

Problems solved by technology

[0003] However, stainless steel, aluminum, iron and other materials also have their limitations in the application of kitchen utensils and small household appliances, which are reflected as follows: ①Due to the characteristics of conventional metal materials such as stainless steel, aluminum, iron, etc. The temperature of the material is always rising during the process, and it can reach hundreds of degrees Celsius in a few minutes, while the general cooking temperature only needs to be 100°C to 200°C; in addition, conventional metal materials such as stainless steel, aluminum, and iron, The material itself does not have non-stick properties. Non-stick coatings are often used in the kitchenware and small household appliance industries to solve the non-stick problem of products. However, the suitable temperature for use of non-stick coatings is below 260°C. When the temperature exceeds 260°C, the coating It will be in an unstable state and will release harmful substances at high temperatures. Therefore, the anti-dry function of non-stick pans using conventional metal materials such as stainless steel, aluminum, and iron has not been well improved, mainly because the pan material does not have a constant temperature. requirements, not controlled within the appropriate temperature range

At the same time, there is no ideal material suitable for non-stick pans on the market at present.
