Embodiment 1

[0016] Outsourcing:

[0017] Graphene powder, specifications: powder, particle size: 30-60nm.

[0018] Infrared emitter, specification: powder.

[0019] High temperature resistant phenolic resin, specification: liquid.

[0020] Weigh 4 parts of graphene powder, 2 parts of far-infrared emitter, and 5 parts of high-temperature-resistant phenolic resin, mix the graphene powder and far-infrared emitter and stir evenly, then add bonding diluent and mix to form a slurry.

Embodiment 2

[0022] Apply the slurry described in Example 1 evenly to the film formed on one surface of the fiber fabric, and dry (or dry) to form a graphene radiation heating film.

[0023] The fiber fabric containing the graphene radiation heating film and the same fiber fabric without the graphene radiation heating film were simultaneously carried out under the condition of simulated body temperature (37°C) to compare the heat preservation and radiation effects of the heat source, as shown in Table 1:

[0024] Table 1:

[0025]

[0026] The results prove that the graphene radiative heating film can radiate heat and is used to make bed sheets, quilt covers or underwear. Under the action of a heat source, it can radiate infrared wavelengths of 8-14um, and has a good heat preservation effect.

Embodiment 3

[0028] The fiber fabric containing the graphene radiation heating film obtained in Example 2, in the absence of a heat source, is only stimulated by the external environment temperature to generate heat, which emits little heat and also has a small amount of infrared wavelength radiation of 8-14um.

Abstract

The invention relates to a graphene radiation heating film and the preparation method and application thereof. The graphene radiation heating film is formed by coating graphene sizing agent on a surface of fiber fabric; the graphene sizing agent is formed by mixing the following components in part by weight: 3 to 5 parts of graphene powder, 1 to 3 parts of far-infrared cast charge and 4 to 6 parts of bonding diluent; the preparation method comprises the following steps: weighting graphene powder of 3 to 5 parts by weight, far-infrared cast charge of 1 to 3 parts by weight and bonding diluent of 4 to 6 parts by weight, after mixing the graphene powder with far-infrared cast charge, stirring the mixture uniformly firstly, then adding bonding diluent and mixing, so as to form sizing agent; coating the sizing agent on the surface of the fiber fabric to form a film, and after the film is dried in the air or dried by baking, the graphene radiation heating film is formed. During use, the graphene radiation heating film emits heating by radiation under the effect of external temperature.

Description

technical field [0001] The invention relates to a graphene radiation heating film and a preparation method and application thereof. Background technique [0002] Graphene (Graphene) has been reported by Professor Geim of the University of Manchester in 2004. Its unique properties have attracted widespread attention and great interest from scientists, and it is predicted that it is likely to cause revolutionary changes in many fields. Single-layer graphene exists in a two-dimensional crystal structure with a thickness of only 01334nm. It is the basic unit for constructing carbonaceous materials of other dimensions. It can be wrapped up to form zero-dimensional fullerenes, rolled up to form one-dimensional carbon nanotubes and stacked to form three-dimensional ones. graphite. Graphene is a semiconductor without an energy gap, has a carrier mobility 100 times higher than silicon (2 × 10 cm / v), has a micron-scale free path and a large coherence length at room temperature, so ...
