Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a silicone rubber for heat-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot wire for an electric mat, and more particularly, to an electric mattress for protecting an inner core wire and a heating wire from heat, To silicone rubber for hot wire.

The electric mattress is equipped with a heat wire which is electrically heated inside the mattress, and the convenience of use and the heating effect are widely used nowadays.

As shown in Fig. 1, the hot wire is generally composed of a core wire 10 which is an electric resistor, an insulator 20 which shields the core wire, and one or several layers of silicone rubber 30 for insulation or insulation.

Since the electric mats come into contact with the human body, various functions such as heat insulation and electromagnetic shielding are required. In general, silicon rubber is most commonly used.

Natural rubber and general organic rubber are aged in a short time if they exceed 100˚C, but can not be used. Silicone rubber is generally used at temperatures between 150˚C and 250˚C, and can be used up to 300˚C when used intermittently for a short time .

Since the saturation point of general organic rubber is -20 ° C to -40 ° C compared to -60 ° C to -70 ° C, the silicone rubber maintains elasticity almost unchanged even at low temperature at which the organic rubber breaks, Cold resistance is most excellent.

Unlike other organic rubbers, silicon rubber has very good weatherability because it does not have double bonds that react with oxygen, ozone, ultraviolet rays, etc. in the molecular structure to generate cracks.

Silicone rubber has excellent oil resistance at high temperatures, which can not be used with general organic rubber except fluorine rubber.

Silicone rubber has excellent chemical resistance and is hardly affected by polar organic compounds such as acids and alkalis. However, strong acid or strong alkali may be infringed, so if you are used in contact with them, you must decide whether to use after the test.

The radiation resistance of silicone rubber is not particularly superior to that of organic rubber, but it exhibits excellent properties when heat resistance is added. In particular, methylphenyl silicone rubber is superior.

Silicone rubber does not contain a halogen element and therefore generates less toxic gas during combustion.

It has higher thermal conductivity than general organic rubber and can be used as insulation cushion material for insulation coating and heat dissipation electric appliances.

Silicone rubber is physiologically inert because it is essentially harmless to human body and does not induce blood clotting well, making it the most suitable for food and medical products manufacturing.

Silicone rubber has the lowest carbon content in the molecule and it does not use carbon black which is used as filler in general organic synthetic rubber, so it shows excellent resistance to arc or corona discharge lamp under high voltage regardless of temperature and frequency. Is used.

As described above, the silicone rubber has various advantages, and is most often used as a hot wire for an electric mat, but has a problem in that it can not be utilized other than the basic physical properties possessed by silicon.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a silicone rubber which is a heat ray covering material, and which comprises tourmaline, radium and char which are capable of releasing far- So that the health of the matte user can be promoted.

2 to 6% by weight of tourmaline powder having a particle size of 50 to 20 占 퐉 and 1 to 2% by weight of radium powder having a size of 5 to 20 占 퐉 in 90 to 94% by weight of addition type liquid silicone rubber and 20 to 100 占 퐉 in size And 1 to 2% by weight of charcoal is added thereto, followed by stirring and curing the mixture.

As described above, the covering material according to the present invention can continuously emit long-range infrared rays and negative ions, which are beneficial to the human body, in addition to the inherent functions such as the protection of the heating wire and the electromagnetic wave shielding. In particular, tourmaline increases the far infrared ray emission when the temperature rises or the contact property such as friction increases. Since the power is applied to the hot wire, the higher the temperature is, the more far infrared rays are emitted. Since the friction force increases according to the movement of the human body lying on the mat, it is possible to maximize the far infrared emission amount of tourmaline. In addition, radium and charcoal are mixed with silicone rubber, but they are contained in the coating material in fine powder state without any special chemical reaction, so that natural far infrared rays and anion emission can be expected continuously.

1 shows a general heat line.

An embodiment of the present invention will be described as follows.

The covering material according to the present invention is used in an amount of 90 to 94% by weight of an addition type liquid silicone rubber. Here, the addition type silicone rubber is a method of cross-linking the siloxane by addition reaction of a polysiloxane containing a vinyl group and a polysiloxane having a Si-H bond. At this time, a platinum compound is used as a catalyst, and no by-products are generated.

The addition type liquid silicone rubber does not require moisture, and the curing reaction proceeds uniformly inside the surface, and the deep curing property is good. The curing rate is high in temperature dependence, and as the temperature is raised, it hardens in a short time. (Curing inhibitor) that hinders the action of the platinum catalyst during curing of the addition type liquid silicone rubber may be brought into contact with the cured silicone rubber. Examples of such a curing inhibitor include an amine, an organic compound, a sulfur compound, and an organotin (Sn) compound. When they are contained in contact with, for example, condensation type liquid silicone rubber, organic rubber or soft PVC, You need to be careful because there are cases.

The addition type liquid silicone rubber is mixed with 2 to 6% by weight of tourmaline powder and stirred. Tourmaline crushes to a size of 5 to 20 μm. Although the tourmaline powder may be smaller than 5 탆, the powder processing time is long. When it is 20 탆 or more, the tourmaline powder may not be mixed well with agitation, and the surface may become rough when cured. The chemical components of tourmaline are complex borosilicates of iron, magnesium, alkali metals and aluminum. Quartz, muscovite, feldspar, and so on.

Tourmaline produces far infrared rays called so-called nurturing rays. The far-infrared rays act on autonomic nerves and endocrine glands.

In addition, the far infrared rays generated from tourmaline relax the chills, neuralgia and arthralgia by blood circulation promotion and warming maintenance effect, promote the recovery of scars and inflammation by cell activation, and promote the development and growth of the human body.

Far infrared rays emitted from tourmaline infiltrate deep into the body to heat up the cells, improve blood circulation, stabilize living tissues, increase immunity, and maintain metabolism. The far infrared emissivity of tourmaline is close to 100%, which is higher than any other mineral.

Particularly far infrared rays penetrate to 40 ~ 50mm from the inside of the body, and it radiates from the inside of the body. It helps not only the feeling of hot spring bath but also fatigue recovery, blood circulation promotion, immunity enhancement, biotissue activation, skin elasticity maintenance, cold circulation, neuralgia, muscle pain, shoulder stiffness and back pain .

The amount of tourmaline that emits far infrared rays increases as much heat is applied. If you have a product that has been processed with tourmaline or powder, it absorbs the heat energy released from the human body.

The addition type liquid silicone rubber is mixed with 1 to 2% by weight of radium powder. Radium is pulverized to a size of 5 to 20 탆.

Radium is a radioactive material that can adversely affect the human body when mixed in large quantities. However, there are several other effects that can not be replaced by other substances when the amount is too small.

Radium has excellent effects on neuralgia, cracks, rough skin, shoulder stiffness, and fatigue recovery. For example, when you enter the radium spa, you can feel the smooth skin immediately.

In the addition type liquid silicone rubber, 1 to 2% by weight of charcoal powder is mixed. The size of the charcoal powder is pulverized to a size of 20 to 100 mu m. When the content is less than 1% by weight, it is difficult to sufficiently expect the effect of the char. When the content is more than 2% by weight, the ductility and bonding force of the silicone rubber after the liquid silicone rubber hardening is lowered .

The most outstanding effects of charcoal are oxidation and reduction. Charcoal has the power to hold things for a long time and the resilience, which can activate all things around and maintain human health.

If the sickness or sickness is expressed differently, the electrons are separated and the electrons are insufficient. In the low electron part, the charcoal can supply electrons indefinitely.

So, when charcoal is placed around the body, the body will be refreshed and renewed by the reduction action that is always supplied with electrons. Because the electron density of char is much higher than that of people, it always receives energy from charcoal.

Charcoal has the effect of neutralizing acidified material or food and alkalizing it. The body fluid or blood in the body can be neutralized with alkali and kept fresh. About 60% of the components of charcoal are alkaline salts. Nowadays, it is used to improve the acidic soil by using the alkalinity of charcoal or to prevent damage to the acid rain.

A charcoal bath changes the alkalinity of PH 9 to 10 and makes the water molecule smaller, so that it penetrates more and more into the body and improves the blood circulation, as well as neutralizing toxins in the body and skin. It also has high alkalinity and is effective for fatigue recovery and various skin diseases.

Far infrared ray is a kind of electromagnetic wave, which is a beneficial ray that radiates the force of warming the substance to expand the capillary blood of the human body to smooth the blood circulation and circulate the substances of the human body. These rays are emitted from all materials on earth, but especially emissivity is high, such as charcoal, loess, stone, and ceramics. The far infrared ray emitted by charcoal is 93% when the emissivity standard is set at 1.

Charcoal reduces humidity around a dry sponge as it absorbs water, and when it is too dry, it releases moisture to make the humidity more natural. Charcoal baked at high temperature contains little moisture. The structure of the charcoal with a lot of holes brings good humidity control effect.

Contaminated air and water are surprisingly purified when they pass through charcoal. The strong hydrostatic force in charcoal is due to the structure in which charcoal is made porous with many holes. Activated carbon is contained in a gas mask that detoxifies toxic gas, and water such as nutrients, glucose, and amino acids used in hospitals is also filtered with charcoal.

Charcoal has a strong far-infrared effect. Charcoal has the effect of constantly emitting far infrared rays and restoring the diseased cells and diseased cells of our body. In particular, far infrared rays penetrate up to 5cm of skin. In addition, charcoal generates anion to prevent aging of all materials and to block harmful electromagnetic waves. So if you place charcoal around TV or household appliances, it will prevent the generation of electromagnetic waves and reduce damage.

Charcoal suppresses the generation of spoilage bacteria, eliminating the source of odor and adsorbing the odor. Putting charcoal in refrigerator, shoe box, closet, kitchen, automobile etc. can be used for deodorization and also for water filtration. Disinfection such as chlorine When the charcoal is put into the strong smell of tap water, the smell is removed and the water taste becomes better. It is a method that has been used by housewives from ancient times that the smell disappears when the charcoal is put into the rice when the rice is slightly burned.

In addition, there is a record that it was used for the treatment of epilepsy, dizziness, anemia, and anthrax. In oriental herbal medicine, various charcoal was medicinally used, and various kinds of medicines were carbonized. When the charcoal is edible, the ingredients beneficial to the human body are left as they are, and they cause antimicrobial action on harmful viruses in the human body or release harmful bacteria out of the body.
