Abstract
The invention relates to the technical field of intelligent wearing, in particular to a flexible phase-change automatic temperature control device for intelligent wearing and a preparation method thereof. A flexible phase-change automatic temperature control device for intelligent wearing comprises a heat insulation layer, a heat preservation layer and a heat conduction layer which are stacked from top to bottom; the heat insulation layer is a polyethylene layer with a porous fold structure, and the heat insulation layer is a phase change material layer with a honeycomb structure; the heat conduction layer is a polyethylene layer with a porous fold structure. When the heat discharged by the human body reaches a threshold value or the external environment changes, the phase-change material releases heat energy, and the human body is maintained in a relatively comfortable environment. The temperature control can be realized without external other energy.
Description
Technical Field
The invention relates to the technical field of intelligent wearing, in particular to a flexible phase-change automatic temperature control device for intelligent wearing and a preparation method thereof.
Background
In extreme weather conditions, the human body receives or releases energy too quickly, causing an imbalance in the temperature regulation inside the body, which causes damage. On one hand, in areas which are extremely hot and difficult to endure or after the body strenuous exercise, a large amount of accumulated heat of the body needs to be dissipated; on the other hand, in severe cold areas, the body energy is lost too fast; most of the energy of the body is transferred or dissipated in the form of heat, so thermal management is particularly important to reduce energy consumption and improve energy conversion, while energy dissipation in the form of infrared radiation accounts for a significant proportion of heat dissipation. Therefore, the infrared radiation characteristics of the material play a crucial role in achieving efficient thermal management.
The traditional phase change energy storage material generally utilizes the solid-liquid phase change behavior thereof to store energy and control temperature, wherein a phase change material PCM capsule is a relatively common form, a core-shell structure is adopted, organic materials (such as polyurethane, polyurea and the like) are utilized to coat the phase change material (such as paraffin, straight chain fatty alkane and the like), the outer shell structure has no flexibility due to high rigidity, and the inner core material can leak in the phase change process and cannot be applied to the thermal management of flexible wearable devices.
Disclosure of Invention
Aiming at the technical problems, the invention provides a flexible phase-change automatic temperature control device for intelligent wearing and a preparation method thereof, and aims to solve the flexibility problem of applying a phase-change material to a wearable device and reduce the harm of severe external temperature change to a human body.
The invention discloses a flexible phase-change automatic temperature control device for intelligent wearing, which comprises a heat insulation layer, a heat preservation layer and a heat conduction layer which are stacked from top to bottom; the heat insulation layer is a polyethylene layer with a porous fold structure, and the heat insulation layer is a phase change material layer with a honeycomb structure; the heat conduction layer is a polyethylene layer with a porous fold structure.
Furthermore, the diameter of the air hole of the heat insulation layer is 100-600nm, and the thickness is 50-500 μm.
Further, the thickness of the thermal insulation layer is 100-300 μm.
Furthermore, the diameter of the pore of the heat conduction layer is 300-800nm, and the thickness is 25-500 μm.
The invention also provides a preparation method of the intelligent wearable flexible phase-change automatic temperature control device, which comprises the following steps:
(1) preparing a heat insulation layer: carrying out melt spinning on polyethylene and polyethylene oxide to obtain polyethylene fibers, carrying out cold drawing on the prepared polyethylene fibers, soaking the polyethylene fibers to remove the polyethylene oxide to obtain filamentous pore fibers, and spinning to obtain the heat insulation layer;
(2) preparing a heat insulation layer: adding gamma-methacryloxypropyltrimethoxysilane, gamma- (2, 3-epoxypropoxy) propyltrimethoxysilane, an epoxy resin prepolymer, polyethylene glycol 400, polyethylene glycol 800 and polyethylene glycol 1000 into a container, placing the container in a constant-temperature water bath for water bath, heating reactants in the container, adding a catalyst, and stirring; adding gamma-aminopropyltriethoxysilane and maleic anhydride into a container, and stirring; adding an auxiliary agent, and stirring to obtain a glue solution; putting the glue solution into a mold, and obtaining a heat-insulating layer after the micromolecular solvent in the glue solution is completely volatilized;
(3) preparing a heat conduction layer: mixing paraffin and polyethylene in a molten state, melting and pressing the mixture into a film, and extracting paraffin oil to obtain a heat conducting layer;
