Description

A graphene heating combination layer, electric blanket, heating eye mask and warm uterine belt

Technical field

The invention relates to the technical field of graphene, and in particular to a graphene heating combination layer, an electric blanket, a heating eye mask and a warm uterine belt.

Background technique

In the field of graphene low-temperature heating technology, the existing technology uses PET polymer materials or PI film materials as heating carriers, and coats the heating carrier with a heating medium containing graphene to form a foldable graphene heating film. After being sealed, the graphene heating film can easily make crisp noises when folded, curled, or pressed. When the graphene heating film is covered with flexible materials such as cloth and sponge, it will still produce sharp noises once it is folded, curled, or pressed. In order to reduce the noise caused by the graphene heating film due to heating carriers such as PET and PI, a silencing technology must be adopted for the graphene heating film to avoid or reduce the generation or spread of noise, thereby improving the comfort of the product during use.

Traditional silencing technology reduces the energy of sound waves and achieves the silencing effect by lengthening the length of the sound wave transmission buffer channel in the air, that is, using external relative sealing technology to achieve the silencing effect. For graphene series products, PET, PI and other materials are used as heating carrier materials. The materials themselves have great elasticity and are easy to form irregular vibrations with the air to produce noise. If we follow the current noise reduction technology and use airtight The technology is a technical solution that is obviously unrealistic and impractical; adding flexible noise reduction technologies such as cloth and sponge to the surface can only partially alleviate the noise, but cannot fundamentally solve the generation of noise. In order to solve the above technical problems, it is necessary to make breakthroughs in theory, find materials that meet theoretical conditions, and reduce or avoid the generation of noise. After long-term research and experiments, to reduce the noise of PET/PI and other materials, the following conditions must be met: 1. The upper and lower parts must not be in direct contact with the air to avoid direct vibration with the air to produce noise; 2. The material covering the surface layer is very elastic. Weak, and the average mass is more than twice the average mass of polymer materials such as PET and PI; 3. The covering material must be in relatively close contact with PET and PI. The patent application document with application publication number CN112702809A discloses a high-heating graphene fiber board, which includes a board body. Splicing structures are provided on both sides of the board body. The outer wall of the board body is provided with a thermal conductive anti-aging structure. A first layer is fixedly connected to the interior of the board body, a second layer is fixedly connected to the interior of the first layer, and sound insulation blocks are fixedly connected to the inner wall of the first layer and the outer wall of the second layer. The space between the first layer body and the second layer body is filled with sound-absorbing cotton, the interior of the second layer body is provided with an impact-resistant structure, and the insulation structure is provided between the plate body and the first layer body. The graphene fiber board cooperates with the sound insulation block and silencer cotton to greatly improve the sound insulation effect and reduce the spread of noise. However, this sound insulation structure is thick and is not suitable for folding. It is only suitable for graphene fiber boards with plate-like structures. .

At the same time, the planar heating technology used in graphene materials will easily accumulate heat and generate high temperatures after long-term operation, which may lead to combustion accidents. In order to improve the safety performance of the product, it is necessary to have comprehensive coverage of Class A fireproof materials to improve the safety of the product. sex.

The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Example 1:

This embodiment provides a graphene heating composite layer, as shown in Figure 1 , including a foldable graphene heating film 1 and an inorganic fiber cloth layer 2. The graphene heating film 1 is disposed between two inorganic fiber cloth layers 2 and the upper and lower surfaces of the graphene heating film 1 are connected to the inorganic fiber cloth layer 2 respectively. The inorganic fiber cloth layer 2 is attached to the upper and lower sides of the graphene heating film 1 . Among them, the graphene heating film 1 is an existing technology that can generate heat when energized, and more than 80% of the energy of the light waves it emits is concentrated in the wavelength region of 4.5-8um. A large amount of far-infrared light waves of this wavelength are absorbed by the human body, and resonate with the far-infrared light waves released by the human body. After forming resonance, they are reabsorbed by the human body and reused; the far-infrared light waves of this band can enter the human body at a vertical depth of 5-8cm, thereby entering The internal organs and tissues of the human body and the blood circulation system of internal organs achieve the enhancement of blood circulation within the organs and the improvement of the environment.

When sound propagates, when an object vibrates, it will cause the molecules of the medium (such as air) to vibrate rhythmically, causing the density of the surrounding medium to change, forming longitudinal waves of alternating density, and sound waves are generated. The propagation of objects in the air is affected by the object's own mass density and its own elasticity. The base material of graphene heating film 1: PET, PI and other polymer materials are organic materials with high elasticity. When subjected to external force, their own molecules can elastically collide with molecules in the air, causing the molecules in the air to vibrate rhythmically. The resonance between air molecules causes noise. The inorganic fiber cloth layer 2 is an inorganic material with low elasticity, and the mass density of the inorganic fiber cloth layer 2 is much greater than the mass density of air (nearly 1000 times). When the inorganic fiber cloth layer 2 is vibrated by the outside world, After the molecules in the air hit the inorganic fiber cloth layer 2, they directly accelerate the reverse movement. It is difficult to form a resonance between the vibration of the inorganic fiber cloth layer 2 cloth and the air, thus reducing the generation of noise. When the inorganic fiber cloth layer 2 is covered on the graphene heating film 1, it can effectively block the contact between the graphene heating film 1 and the outside air. The vibration energy of PET or PI is transmitted to the glass fiber cloth with almost no loss, and the noise energy cannot be directly transmitted. When exposed to air, due to the blocking effect of fiberglass cloth, PET or PI cannot resonate with molecules in the air, thereby reducing noise. The graphene heating composite layer in this embodiment covers inorganic fiber cloth layers on both sides of the graphene heating film 1. The inorganic fiber cloth layer can effectively block the crisp noise emitted by the graphene heating film 1 when folded and pressed, so that The noise is reduced from 40-50 decibels to 10-25 decibels, improving the comfort of the product. In addition, the inorganic fiber cloth has flame retardant function layer by layer, which can play a fire prevention role and improve product safety. Therefore, the inorganic fiber cloth layer not only plays a role in noise reduction but also plays a fire prevention role, effectively protecting the graphene heating film 1 .

Preferably, the inorganic fiber cloth layer 2 is a fiberglass cloth layer or a basalt cloth layer, and the fiberglass cloth layer or the basalt cloth layer is attached to the upper and lower surfaces of the graphene heating film 1 . The upper and lower surfaces of the graphene heating film 1 can be covered with a fiberglass cloth layer or a basalt cloth layer.

The fiberglass cloth in this embodiment is also called fiberglass cloth. Its main components are: silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc.; density: 2.4-2.76g/cm; glass fiber is higher than organic The fiber has high temperature resistance, non-flammability, corrosion resistance, good heat and sound insulation, high tensile strength and good electrical insulation. The base material of graphene heating film 1 is PET polymer material, its relative molecular weight is generally 18,000-25,000, and its density is 1.37-1.4 grams/cubic centimeter. In this embodiment, a fiberglass cloth layer is placed to cover the outside of the graphene heating film 1. When the fiberglass cloth layer and the graphene heating film 1 are closely attached, the base material (PET or PI) of the graphene heating film 1 is formed. When vibrating, the vibration energy is transferred to the fiberglass cloth. The vibration energy of PET or PI is transferred to the fiberglass cloth with almost no loss, and the noise energy cannot be directly transferred to the air. Due to the blocking effect of the fiberglass cloth, PET or PI cannot interact with the air. The molecules in them resonate, thereby reducing noise. Even if there is a partial gap between the fiberglass cloth layer and the graphene heating film 1, the vibration energy of the graphene heating film 1 will propagate back and forth between the fiberglass cloth layer and the graphene heating film 1. Due to the huge density difference between the fiberglass cloth and the air, It is not easy to resonate with the outside air and generate noise, so the fiberglass cloth reduces the noise generated by the graphene heating film 1. Experiments have proven that the sound emitted by PET polymer material alone is louder than the sound of normal communication between people, about 40-50 decibels. The sound emitted after adding fiberglass cloth is about 10-25 decibels, which effectively reduces the noise. Noise emitted by PET polymer materials.

The waterproof membrane layer 4 in this embodiment serves as a water barrier, preventing external moisture from entering the inside of the waterproof membrane layer 4 and protecting the graphene heating film 1 . In the product's water intrusion experiment, the graphene heating film 1 was passed through a high voltage of 3000V, and the external current of the waterproof film layer 4 was less than 100ma. The waterproof film layer 4 also played a role in ensuring the insulation safety of the product.
