Description

Technical Field

[0001] The invention relates to the field of functional wall panels, and in particular to an embedded magnetic health functional wall panel and a preparation method and application thereof. Background Art

[0002] The earth not only provides humans with mountains, rivers, flowers, birds, insects and fish, but also provides humans with a magnetic field environment for survival and reproduction. The earth's magnetic field is a magnetic field distributed in the space around the earth, with its magnetic south pole near the geographic north pole and the magnetic north pole near the geographic south pole. The magnetic lines of force point from the geographic south pole to the geographic north pole, and the direction of the magnetic field near the equator is roughly parallel to the earth's surface, and the magnetic field near the poles is roughly perpendicular to the earth's surface. The earth's magnetic field consists of three parts: the basic magnetic field, the exogenous magnetic field and the magnetic anomaly magnetic field. The basic magnetic field is mainly formed by the convection of electric currents in the earth's core. It is an endogenous magnetic field that accounts for more than 99% of the earth's magnetic field. The exogenous magnetic field is a variety of short-term magnetic changes that originate from outside the earth and are superimposed on the basic magnetic field, such as sunspot activity and magnetic storms. Magnetic anomaly refers to the secondary magnetic field formed after rocks, minerals and other geological materials are magnetized by the earth's magnetic field. The influence range is limited (the schematic diagram of the earth's magnetic field is shown in the figure). Figure 1 shown).

[0003] The Earth's magnetic field changes in strength and direction periodically. According to research, the Earth has experienced 171 magnetic pole reversals in the past 76 million years, and the Earth's magnetic field strength decays to zero and a magnetic pole reversal occurs every 444,000 years on average. Paleomagnetic scientists have found that the most recent magnetic pole reversal occurred 700,000 years ago, and is now approaching the critical point for the next magnetic pole reversal. In addition, the magnetic field strength in North America has weakened by 50% in the past 4,000 years, further confirming that the Earth's magnetic field is currently in a decaying stage.

[0004] The human heart, lungs, brain, muscles and nerves all have micro-magnetic fields to varying degrees. Since the birth of mankind, our growth and evolution have been closely related to the earth's magnetic field. A stable and moderate magnetic field environment has an important protective and promoting effect on human health. However, with the advent of industrialization and urbanization, the high-rise buildings built of reinforced concrete and the use of metal-shell transportation vehicles such as cars and subways have formed a certain barrier to the natural magnetic field, further weakening the earth's magnetic field.

[0005] Studies have shown that the magnetic field strength that the human body can adapt to is about 50 microteslas (μT). my country's requirement for magnetic field strength is that it cannot exceed 100 microteslas (μT) for a long time. In residential environments, normal magnetic field strength is usually between 0.05 and 0.5 microteslas (μT). In 1999, the German Federal Office for Radiation Safety tested the magnetic field radiation of some household appliances. The results are shown in Table 1:

[0006] Table 1

[0007]

[0008]

[0009] As can be seen from the table above, household appliances will have an impact on the magnetic field of the residential environment, among which hair dryers, electric shavers, vacuum cleaners and microwave ovens have the greatest impact. The use distance of electric shavers is the shortest, and the derived magnetic field strength exceeds the human body's tolerance threshold, but the use time is basically within 1 minute, so the impact is limited. The use distance of hair dryers, vacuum cleaners and microwave ovens is usually close to or exceeds 30cm. Although they can play a certain role in magnetic supplementation, the use time is generally less than half an hour, and the magnetic field supplement is limited. As for household appliances such as fluorescent lamps, washing machines, computers, refrigerators and color TVs, because the use distance is far, even if they are used for a long time, the supplement to the residential magnetic field is very limited.

[0010] Medical research shows that a stable weak magnetic field has many benefits for the human body. For example, under the action of the magnetic field, the volume of red blood cells increases, the blood vessels expand, and the diameter becomes larger, thereby increasing the oxygen carrying capacity and accelerating the blood flow rate, which can improve the nutritional status of tissues, increase blood oxygen saturation, reduce blood viscosity, increase immunoglobulin and lymphocyte conversion rate, reduce the formation of cholesterol and fat, and promote metabolism. For another example, the autonomic nerves of the human body control the movement response of the heart, stomach and other internal organs. When the human body is in a constant magnetic field for 30 minutes, the heart rate will slow down, blood pressure will drop, breathing will slow down, etc., which is conducive to deep sleep and body repair. However, the weakening of the magnetic field will induce electrical abnormalities in human blood, lymph and other body fluids, leading to premature cell aging, increased blood viscosity, blood sediments blocking blood vessels, etc., affecting human health and inducing various diseases.

[0011] Therefore, it is crucial for human health to properly apply an external magnetic field to supplement the earth's magnetic field and be in the magnetic field for several hours. In other words, developing wall panel products with built-in magnetic health functions and applying them to living spaces, especially bedrooms, is of great significance to human health. Summary of the invention

[0012] Based on the above content, the present invention provides an embedded magnetic health functional wallboard and its preparation method and application. The embedded magnetic health functional wallboard of the present invention adds a permanent magnetic block with a specific magnetic field strength, which can enhance the magnetic field strength of the living space to a certain extent and compensate for the weakened part of the natural magnetic field, thereby regulating microcirculation, regulating blood components, regulating the nervous system, improving sleep, etc., and better protecting human health.

[0013] To achieve the above object, the present invention provides the following solutions:

[0014] One of the technical solutions of the present invention is an embedded magnetic health care functional wall panel, comprising a polyvinyl chloride (PVC) foam wall panel and a permanent magnet;

[0015] The polyvinyl chloride foam wallboard is provided with semi-permeable holes and / or semi-permeable grooves;

[0016] The permanent magnet is arranged in the semi-permeable hole and / or the semi-permeable groove.

[0017] The second technical solution of the present invention is a method for preparing the above-mentioned embedded magnetic health functional wallboard, comprising the following steps:

[0018] After semi-permeable holes and / or semi-permeable grooves are drilled on the polyvinyl chloride foam wallboard, the semi-permeable holes and / or semi-permeable grooves are coated with structural adhesive, and then permanent magnets are embedded. A PVC sheet with structural adhesive is attached to the surface of the permanent magnet and cured at a constant temperature to obtain the embedded magnetic health functional wallboard.

[0019] A third technical solution of the present invention is the application of the above-mentioned embedded magnetic health functional wall panels in residences, office buildings, hospitals or hotels.

[0020] The present invention discloses the following technical effects:

[0021] The embedded magnetic health-care functional wallboard of the present invention not only retains the various styles and exquisite shapes of traditional wallboard products, but also artificially increases the magnetic function of the wallboard products, and does not contain formaldehyde, and the formaldehyde emission is at the ENF level. That is, by embedding a permanent magnet with a specific magnetic field strength inside the PVC substrate, it can compensate for the weakened part of the natural magnetic field as much as possible, strengthen the magnetic field environment in the space, and thus better play the role of regulating microcirculation, regulating blood components, regulating the nervous system, improving sleep, etc., and promoting physical health, and playing a certain auxiliary effect on human health.

[0092]

[0093] Note: Use a handheld digital magnetic field strength detector (such as Figure 6 As shown), level five, accuracy ±5%, and other electrical appliances are not started.
