THE PROCESS OF A NEW THERMOSETTING MINERALS RESINS WITH THE MINERALS OR THE PURE MINERALS EMITTING INFRAD-RAYS MIXING WITH THE THERMOSETTING RESINS Technical Field
[1] The present invention relates to a method of preparing a thermosetting material using a powdered pure mineral or rock emitting far- infrared rays as a filler, and more particularly, to a method of preparing a material emitting far-infrared rays beneficial to a human body and having environment friendliness and a high added value. Background Art
[2] A thermosetting resin made of melamine and formaldehyde, which was invented in
Germany in 1936, is a kind of an amino resin acquired from condensation of a compound containing an amino group -NH and an aldehyde. Melamine has three amino groups and thus has six functional groups that react with formaldehyde.
[3] The melamine becomes an initial reaction mixture called poly methylol melamine including many methylol groups HOCH - or (CH2) (OH) - based on a mixture ratio
2 n n and reaction conditions.
[4] In a general method of preparing the thermosetting resin, 1 mole of melamine and
3.3 moles of formaldehyde are mixed, and sodium carbonate or ammonia is added to make the mixture to be moderately alkaline. The mixture is then reacted at a temperature of about 8O0C to be shaped as syrup having an aqueous solution phase.
[5] Conventionally, this syrup is melted in water-alcohol, and the melted syrup is mixed with a filler such as pulp, cellulose powder, asbestos, or glass fiber corresponding to about 40wt % of the total weight. The mixture is then dried to have a water content less than 0.5%, and the dried mixture is pulverized into fine particles.
[6] Thereafter, a colorant and a release agent are simultaneously added to the fine particles, and the fine particles are pressed and heated to prepare a shaped product having excellent properties such as heat resistance, water resistance, acid resistance, alkali resistance, and arc resistance over a urea resin used in dishware, convenience goods, electric appliances, and the like.
[7] The thermosetting resin has a heat resistance. Accordingly, a first resin solution of the thermosetting resin permeates papers, and the overlapped papers are pressed and heated, thereby preparing a strong decorative laminate, which is a main product of melamine resins.
[8] Generally, only the surface of the decorative laminate is a melamine resin layer, and the inside and bottom part of the decorative laminate are mostly made of a plastic or phenol resin layer, which is comparatively inexpensive. In addition, on the decorative laminate, various patterns such as wood grain may be formed by printing the corresponding patterns on the outmost surface of the decorative laminate.
[9] However, in the conventional method of preparing the thermosetting resin, it is impossible to use a powdered pure mineral or rock emitting far-infrared rays as a filler, and the thermosetting resin can be shaped is prepared only at the water content of about 0.5%. In addition, when the conventional method is used, the manufacturing cost is high and the thermosetting resin cannot be recycled. Disclosure of Invention Technical Problem
[10] Effects of far-infrared rays on a human body have been reported such as a heating effect, increase in blood flow, acceleration of metabolism, stimulation of perspiration, alleviation of pain, and other bio- activation effects. In 1835, electromagnetic waves having wavelengths larger than that of a red ray among visible rays were named infrared rays by A. Amper, after the electromagnetic waves having a thermal efficiency higher than that of visible rays and an effect of increase in temperature were found by F. W. Hershel in l800.
[11] Among the infrared rays, rays having a property of reflection, of which wavelengths are below 4 D or less, are called near-infrared rays and rays having a property of absorption, of which wavelengths are above 4 D or more are called far- infrared rays. When the far- infrared ray is emitted onto the human body as a thermal energy source to permeate a human body to a depth of 40mm, bacteria responsible for causing various diseases located within a radiation distance of the far- infrared ray are weakened due to the heat. Particularly, in the case of the human body, the far- infrared ray is known to stimulate the blood circulation by expanding capillary vessels and to support stimulation of generation of cell organizations.
[12] Accordingly, the object of the present invention is to provide a method of preparing a material using a powdered pure mineral or rock emitting far-infrared rays as a filler, and more particularly, to provide a method of preparing a material having excellent properties of a thermosetting resin such as heat resistance, water resistance, acid resistance, alkali resistance, and arc resistance and having light weight, high strength, high density, while emitting far-infrared rays. In addition, the material is recyclable, and the manufacturing cost of the material is low.
[13] The present invention provides the method of preparing the material, which improves conventional thermosetting resin products and can prepare the thermosetting
material having a high added value. Technical Solution
[14] According to an aspect of the present invention, there is provided a method of preparing a material emitting far- infrared rays using a thermosetting resin, the method includes a pH adjustment process, a mixing process, a drying process, and a materialization process.
[15] In the pH adjustment process, a pH modifier is added to the thermosetting resin made by a conventional method, as needed. In the mixing process , the thermosetting resin corresponding to 20 wt% to 60 wt% of the material and a powdered pure mineral or rock as a filler emitting far- infrared rays corresponding to 80 wt% to 40 wt% of the material are mixed so as to amount to 100 wt%. In the drying process, the mixed material is dried so as to adjust a final water content of the mixed material to be in the range of 1% to 8% as needed. In the materialization process, the dried mixture is processed to be in a form of a powder or granule. Best Mode for Carrying Out the Invention
[16] Hereinafter, the present invention will be described in detail.
[17] In a pH adjustment process, a general pH modifier is directly added to and mixed with a thermosetting resin, which is prepared by a conventional method, using a mechanical tool or the like for attaining a required pH. The pH-adjusted thermosetting resin corresponding to 20 wt% to 60 wt% of a material and a powdered pure mineral or rock a powdered pure mineral or rock as a filler emitting far-infrared rays corresponding to 80 wt% to 40 wt% of the material are used so as to amount to 100 wt% of the material.
[18] At this time, a transition metal oxide such as TiO2, MnO, Fe2O3, CuO or CoO may be added to the filler for improving the radiation of the far-infrared rays.
[19] In a mixing process, in which a mechanical tool or the like is used for sufficient mixing of a melamine resin having a networked structure and the filler, the viscosity of the mixed material has a close relation with the subsequent drying process.
[20] The mixing time is determined based on the used mechanical tool so as to perform sufficient mixing. When the viscosity of the material to be mixed is low, it takes a long time to perform the drying process to satisfy a condition in which the water content of the granular particles or the powdered material is in the range of 1% to 8% after the drying process.
[21] Thus, when a viscometer is used considering the subsequent drying process while the mixing process is performed, a constant viscosity of the prepared material can be maintained regardless of the mechanical tool to be used.
[22] In the drying process, the mixed material which has gone through the mixing
process is dried so as to have the final water content in the range of 1% to 8% according to the usage of the material. The drying process can be performed by a method capable of controlling temperature and humidity such as a hot air drying method, a spray method, or a natural drying method.
[23] In this case, the measurement of the water content can be performed, for an example, by a loss of dry weight method in which the water content of a material is measured before the drying process, and the water content of the material is re- measured after the drying process.
[24] The temperature and humidity in the drying process are sensitive to the surrounding environment, and thus a hygro-thermometer having a sensor may be used to control the water content of the material to be in the range of 1% to 8%, which is essential to the material prepared according to an embodiment of the present invention.
[25] Preferably, the dried material may be granulated into granular shapes or grinded by a granulator or a grinder after the drying process so that the final water content of the resultant material is in the range of 1 wt% to 8 wt%, as needed.
[26] In this case, the shape of the prepared material is determined based on easiness of storage and the usage of the prepared material. In addition, a room-temperature hardener or a heating hardener may be added to the material, as an additive which hardens the thermosetting resin by incurring bridge bonds. Also, a stabilizer or the like may be added to the thermosetting resin.
[27] Using the material prepared by the processes described above, products can be mass-produced by pressing and heating all deformable multi-purpose living products, construction materials, or environmental products. In addition, high value-added products capable of emitting far-infrared rays, which is beneficial to a human body, having environment friendliness and a high quality, which have been conventionally impossible to be implemented to the thermosetting resin products, can be mass- produced at a low cost.
[28] While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims. Industrial Applicability
[29] Accordingly, a product made of the new thermosetting mineral resin according to a method of preparing a new thermosetting resin can have various patterns including a wood grain using conventional transfer paper preparing method. In addition, the product made of the new thermosetting mineral resin emits a far-infrared ray and ac-
cordingly the product causes an antibacterial reaction, by which bacteria causing various diseases are weaken due to the heat, stimulates the blood circulation by expanding capillary vessels, and supports stimulation of generation of cell organizations, resulting in good effects on a human body. In addition, as an effect of the antibacterial reaction, food can be stored for a long time without decaying, thereby reducing food wastes and saving money. Also, the product made of the new thermosetting resin can be recycled.
