Graphene nanometer far-infrared negative ion multifunctional electric heating screen and preparation method thereof

Abstract

The invention belongs to the field of functional materials and electric heating elements, and particularly relates to a multifunctional graphene nano far-infrared anionic electric heating screen and a preparation method of the electric heating screen. Each electric heating screen unit mainly comprises universal wheels, a screen frame, a power line and a screen partition plate, wherein the screen partition plates are mounted on the inner sides of the screen frames; the universal wheels are arranged at the bottoms of the screen frames; the power lines are arranged on the side faces of the screen frames; the adjacent electric heating screen units are connected by double-action hinges; the screen partition plates consist of heating drawing plates, glue layers, thermal insulation layers and back plates; the two sides of the thermal insulation layers are respectively connected with the heating drawing plates and the back plates by the glue layers. According to the electric heating screen, graphene serves as a heating raw material and is composited with a plant fiber to prepare a graphene nano far-infrared anionic composite fiber conductive heating layer, and then organic silica gel is composited with non-woven cotton cloth and the like to prepare the electric heating screens in various shapes. The transparent conduction characteristic of the graphene is utilized as an electric heating film, so that the electric heating screen has the significant characteristics of high heating efficiency and uniform heating.

Description

technical field [0001] The invention belongs to the field of functional materials and electric heating elements, in particular to a graphene nanometer far-infrared negative ion multifunctional electric heating screen and a preparation method thereof. Background technique [0002] Screens are widely used as furniture in meeting rooms, office spaces, restaurants and homes, as temporary partitions for isolating spaces or decorations for decoration. Folk style usually consists of more than two foldable or push-pull screen frames. There are wood carving patterns and artistic calligraphy and paintings embedded in the middle. [0003] However, the function of screens on the market is relatively simple, and they only play the role of isolating and beautifying the space. When the indoor weather is relatively cold, it is usually necessary to purchase a heater, which takes up space and is inconvenient.
