Description

Bionic conductive material for generating energy spectrum similar to human body and preparation method thereof

Technical Field

The invention relates to the technical field of production of energy spectrums similar to human bodies, in particular to a bionic conductive material for generating energy spectrums similar to human bodies and a preparation method thereof.

Background

The characteristic wavelength of the energy spectrum of human body radiation is 4-15 mu m, wherein the wavelength peak values are respectively distributed in the following places according to characteristic dominant arrangement: 7-8 μm, 8-9 μm, 9.5-10.5 μm, 11-12 μm, 5-6 μm, about 14 μm, wherein there is no peak at 8 μm. In the medical or health care field, an energy wave with a wavelength of 4-15 μm is generally called a "life wave", but actually, only energy waves with characteristic peaks of 7-8 μm, 8-9 μm, 9.5-10.5 μm, 11-12 μm, 5-6 μm and about 14 μm are real "life waves", and according to the harmonic resonance principle, energy waves with the same characteristic peaks can be absorbed by a human body, and other bands and characteristic peaks can bring damages such as overheating, burning, physiological damage and the like to the human body.

According to planck's law: e ═ hc/λ, the energy of the species is inversely proportional to the wavelength. A substance has a wave-particle duality, and its energy wavelength/frequency depends on constituent molecules of the substance, the substance (molecule) is determined, and its own energy is determined. The temperature of the material is also fixed by measuring the energy in the form of heat. Substances with spectral characteristic wavelengths similar to those of the human body radiate at temperatures similar to those of the human body.

Far infrared or life wave technology and products used in the current medical and health care fields generally have the defects of being incapable of being used for a long time (generally, the time per day is not more than 30 minutes) and being incapable of being used for a short distance (generally, the distance between the far infrared or life wave technology and products and the human body is required to be more than 20cm from the human body, or materials such as cotton fabrics, ores and jades are required to be used for heat transition conduction), otherwise, side effects such as overheating, burning, skin pigment precipitation, eye fundus iris damage and skin dryness can occur, and even the skin, the eyes and the like of the human body are damaged or endocrine and microcirculatory system disorders are caused by long use time or excessive use times.

In view of the above, the present invention is particularly proposed.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are conventional products which are not indicated by manufacturers and are commercially available.

Firstly, the embodiment of the invention provides a preparation method of a bionic conductive material for generating energy spectrum similar to human body energy, which comprises the following steps: mixing the raw materials according to parts by weight;

the raw materials comprise the following components: 10-20 parts of conductive particles, 5-15 parts of high-molecular polymer 1, 5-15 parts of high-molecular polymer 2 and 50-80 parts of organic solvent; the particle size of the conductive particles is 1-2 microns, the glass transition temperature of the high polymer 1 is 100-200 ℃, and the glass transition temperature of the high polymer 2 is 50-80 ℃.

The bionic material provided by the invention releases energy with a frequency spectrum consistent with that of a human body, and the energy can be quickly absorbed by the human body according to a harmonic resonance principle, so that when the human body is covered or irradiated by the energy, the energy cannot be gathered on the surface of the human body or at a contact part of the human body in a heat manner, the temperature is always close to that of the human body, and the rising or scalding cannot be caused. The energy is consistent with human body and is quickly absorbed by the human body to participate in the biochemical reaction process of the human body, so the biological energy-saving capsule has unexpected benefits on the functions of the human body, and has obvious effects on improving the immunity of the human body, improving various sub-health conditions, optimizing bone tissues, muscle tissues and cell tissues and treating related diseases.

Specifically, the weight part of the conductive particles may be any one or a range between any two of 10 parts, 12 parts, 14 parts, 16 parts, 18 parts, and 20 parts. The parts by weight of the high-molecular polymer 1 and the high-molecular polymer 2 may be in the range of any one or two of 5 parts, 7 parts, 9 parts, 11 parts, 13 parts and 15 parts. The weight part of the organic solvent may be any one or a range between any two of 50 parts, 52 parts, 54 parts, 56 parts, 58 parts, 60 parts, 62 parts, 64 parts, 66 parts, 68 parts, 70 parts, 72 parts, 74 parts, 76 parts, 78 parts, and 80 parts.

As used herein, "glass transition temperature" is the temperature at which a polymer changes from a highly elastic state to a glassy state, and refers to the transition temperature from a glassy state to a highly elastic state or vice versa in an amorphous polymer (including amorphous portions of a crystalline polymer).

The high molecular weight polymer 1 may be selected from any polymers having a glass transition temperature of 100 to 200 ℃, and the glass transition temperature of the high molecular weight polymer 1 may be specifically in a range of one or both of 100 ℃, 120 ℃, 140 ℃, 160 ℃, 180 ℃ and 200 ℃. Preferably, the high molecular polymer 1 is at least one selected from the group consisting of polymethyl methacrylate, polycarbonate, and polystyrene.

The high molecular weight polymer 2 may be selected from any polymers having a glass transition temperature of 50 to 80 ℃, and the glass transition temperature of the high molecular weight polymer 2 may be specifically within a range of any one or two of 50 ℃, 52 ℃, 54 ℃, 56 ℃, 58 ℃, 60 ℃, 62 ℃, 64 ℃, 66 ℃, 68 ℃, 70 ℃, 72 ℃, 74 ℃, 76 ℃, 78 ℃ and 80 ℃. Preferably, the high molecular polymer 2 is at least one selected from the group consisting of polyvinyl chloride, polyethylene terephthalate, and nylon-6.

The high molecular polymer 2 with the glass transition temperature of 50-80 ℃ is selected because when the temperature reaches the glass transition temperature, the specific volume of the high molecular polymer 2 is increased and the increase is larger than that of the carbon particles, the distance between the carbon particles which are dispersedly arranged is increased, the conductive channel is blocked, and meanwhile, the volume resistivity and the dielectric constant of the polymer are increased, so that the resistance of the coating material is greatly improved, the insulating property is improved, the heating property is reduced, and the temperature is not increased any more. Therefore, the temperature is safe and automatically controlled.

In addition, when the external environment temperature obviously exceeds the glass transition temperature of the high polymer 2, the dielectric loss of the high polymer 2 is increased, so that the polymer 2 has a certain heating performance, the temperature of the material is promoted to continuously rise, and the self-temperature-control performance of the polymer 2 is reduced. In case this occurs, when the temperature rises to the glass transition temperature of the high molecular weight polymer 1, the specific volume of the high molecular weight polymer 1 increases, and the volume resistivity and the dielectric constant also increase, thereby increasing the effect of the second layer self-temperature control.

In the organic polymer materials with the temperature self-control function on the market, the crystallization temperature of the crystalline polymer resin is taken as a factor for controlling the temperature, so that the temperature control effect is not ideal, such as the temperature cannot be controlled, the fatigue resistance is poor (the temperature control performance is reduced or disappeared after working for a certain number of times), the recoverability is not provided (once the temperature exceeds the crystallization temperature of the used resin, the temperature control performance is reduced or disappeared after cooling), and the like. This is because the melting point is the upper limit of the use of the crystalline polymer resin, and once the temperature reaches around the crystallization temperature, the crystalline polymer starts to undergo melting phase transition, the phase state, molecular structure, and the like of the entire continuous phase polymer change, the material undergoes qualitative change and destruction, and recovery cannot be performed after the temperature drops, so that the temperature control performance, fatigue resistance, and recovery of the product are not guaranteed.

The invention finds that the key point of the self-temperature-control high polymer material is the glass transition temperature of the amorphous polymer non-conducting continuous phase, and the physical properties such as the specific volume, the thermal expansion coefficient, the refractive index, the thermal conductivity, the dielectric constant, the dielectric loss and the like of the copolymer are changed in the processes of glass transition and secondary transition, but the form and the phase state of the material are not changed. The change rule of physical properties in the process is fully utilized to realize effective, anti-fatigue and recoverable self-temperature-control performance.

And laying heat-insulating layers below and above the test example, and sealing and covering. The heat preservation that this test example adopted does: thickness of 2cm, density of 35kg/m³And B1-grade flame-retardant extrusion molding insulation board. The test scheme is as follows: each time of electrifying for 4 hours, ensuring that the highest heating temperature is reached; then cooling for at least 24 hours to ensure sufficient cooling; the maximum temperature reached for each test case was recorded. The test results are shown in Table 1.

Comparing examples 1-9 with comparative examples 1-12 in conjunction with the data in Table 3, it can be seen that: the materials of the embodiments 1 to 9 have different components, when the materials are not covered by a human body, no temperature control and gear shifting device is needed, the temperature does not rise any more when reaching a certain maximum, accidents such as overheating and fire can not occur, the safety temperature self-control performance is obvious, the performance is stable, and the safety temperature control temperature is near the glass transition temperature of the polymer 2. Comparative example 3, the safety control temperature was 94 ℃ higher. Comparative examples 1, 2, 4, 6, 7, 9, the safety self-temperature control performance was deteriorated or lost with the increase of the working time and the number of times. Comparative examples 5 and 11 in the case of covering, the temperature rapidly exceeded 100 ℃, after which the test was stopped and, if it continued to cause overheating or fire accidents, without the safety self-temperature control effect, overheating, burning or even fire accidents occurred.
