The present invention relates to a method for manufacturing a polystyrene (PS) molding with a far-infrared ray or anion-containing composition having an excellent deodorizing effect and a molding product produced by the method, and more particularly, A method of manufacturing a polystyrene molding comprising adding a far infrared ray or anion detoxifying composition capable of providing an environmentally friendly living space by absorbing toxic substances such as heavy metals as well as environmentally harmful substances causing allergies, rhinitis, To a molding product made by the method.

Generally, a molding is attached to a curved portion such as a corner portion of a wall during an interior work, and this is called a decorative molding.

For example, such decorative moldings have been enlarged both indoors as well as outdoors, and they have been widely used for a variety of applications such as ceiling molding, which is a basic molding for decorating the rim of the finished wall surface, And the interior decoration effect is enhanced through this.

Such decorative moldings are manufactured and used in various materials. Typical examples thereof include expanded polystyrene (EPS) molding, MDF molding, PVC molding, wood molding, MDF kelp molding, artificial stone molding and the like.

On the other hand, if you look at the moldings used for the interior decoration of apartments and buildings, MDF molding or PVC molding is mainly used for apartments, and a small number of wooden moldings are used. However, polystyrene moldings are also used for bathroom, porch mirror frame, And the like. MDF molding, polystyrene molding, and PVC molding are mainly used for general houses, one-room and commercial buildings, and MDF molding, wood molding, polystyrene molding and PVC molding are mainly used for power houses.

The foamed polystyrene moldings (including polystyrene moldings), which are widely used, are white and light, and they are excellent in water resistance, insulation, soundproofing, buffering and molding processability and therefore can be used in various industries such as packaging materials, building materials, buoyant materials, ornaments, . ≪ / RTI > The material is very similar to the styrofoam. It is cut into a desired size and shape by using heat, and then cut and attached to the inside of a building or an outer wall. After the installation, base coating, intermediate coating and top coating are sequentially performed .

In the case of molding using a synthetic resin material, it is difficult to impart a high-quality feeling due to inadequate surface treatment. Since these materials also release harmful components, they cause various diseases when they are used over a long period of time, .

In other words, because the interior materials used in new buildings and apartments use chemical materials, adhesives, paints, etc., harmful gases such as formaldehyde are released into the air, causing headaches and dizziness. The harmful substances and sick house syndrome (SHS) cause respiratory system and various skin diseases, but there is no way to solve it.

In particular, it is well known that the release of heavy metals such as lead, cadmium, chromium hexavalent copper, mercury, and arsenic is strictly restricted, and the standard is reported by the Ministry of Environment.

Nevertheless, it is true that there have been considerable limitations in the selection of interior materials since there were no effective alternatives.

However, in many patented technologies, such as Patent No. 837495, only efforts to use an interior material having a negative ion emission / far-infrared ray emitting function or yellow soil or charcoal to dilute harmful components emitted from wallpaper and the like have been disclosed, The introduction of an innovative interior material which can effectively prevent the emission of harmful substances by absorbing and eliminating them is in a state of necessity.

FIG. 1 is a flow chart showing steps included in an example of a method of manufacturing a far infrared ray or anion-containing composition-added polystyrene molding according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the scope of the present invention is not limited thereto.

FIG. 1 is a flow chart showing steps included in an example of a method of manufacturing a far infrared ray or anion-containing composition-added polystyrene molding according to the present invention.

As shown in FIG. 1, the method for preparing a polystyrene molding with a far infrared ray or anion-containing composition according to the present invention comprises a first raw material blending step (S100), a first blending material melting and foaming step (S110) A melting step S120, a forming step S130, a cooling step S140, a first transferring step S150, a engraving step S160, and a second transferring step S170.

First, the primary raw material blending step (S100) is a step of blending the main composition for constituting the polystyrene molding according to the present invention at a predetermined blending ratio to obtain desired properties. The main raw material is polystyrene (GPPS) 20 to 35 parts by weight of impact-resistant polystyrene (HIPS), 0.2 to 0.3 parts by weight of a blowing agent, 0.6 to 0.8 parts by weight of a foaming agent, 0.05 to 0.15 parts by weight of an accelerator, 0.05 to 0.15 parts by weight of zinc, 0.05 to 0.15 parts by weight of dioctyl phthalate (DOP) 0.1 to 0.2 part by weight of the antifouling composition and 3 to 5 parts by weight of the composition for far-infrared ray or anion-radiating composition are mixed to constitute the primary blended raw material.

The polystyrene resin is a solid of a thermoplastic resin and is characterized by being lightweight, tasteless, odorless, non-toxic, and excellent insulating property, good in thermal stability and fluidity at the time of melting, and low in molding shrinkage rate and excellent in molding processability. It is usually divided into general purpose polystyrene resin (GPPS), impact resistant polystyrene resin (HIPS), and expandable polystyrene resin (EPS). It is also used by adding special additives. The general-purpose polystyrene is a rigid and rigid material with transparency. The impact-resistant polystyrene is a semi-rigid material produced by polymerizing styrene with polybutadiene (rubber). Expanded polystyrene is made by expanding polystyrene by the action of a foaming agent. % Is air and 2% is resin.

In the present invention, it is added to enhance the tensile force, and is blended in the granular form as the main material of the present invention combination.

Impact-resistant polystyrene (HIPS) is also a type of polystyrene, added in granular form to enhance impact strength, and the combination of general-purpose polystyrene and impact-resistant polystyrene accounts for most of the primary raw material blend of the present invention.

In addition, peroxide (R TiO ₂ ) is added to prepare bleaching and coloring, and refers to titanium dioxide, which is mainly used as a white pigment and photocatalyst. Such a sugar is white powder, chemically very stable, harmless to human body, and widely used in almost all fields such as plastic, paint, medicine, paper and pottery. Particularly, it is classified into anatase and rutile depending on the form. An anatase is referred to as A site and rutile is referred to as R site. In the present invention, R site is used.

It is preferable that 0.2 to 0.3 parts by weight of R is added in the form of powder in the present invention. If less than 0.2 part by weight is added, it is difficult to realize bleaching and coloring. When the amount is more than 0.3 part by weight, overbottom occurs to cause color defects and imbalance .

The blowing agent uses an inorganic foaming agent (NaHCO ₃ ), which is a chemical foaming agent. Here, the term "foaming" means that a foaming agent is added to the structure of plastic and rubber to generate gas under a certain temperature, pressure and time to form a foam having a cell.

Such foaming is aimed at lighter weight of a product, cushioning property, buoyancy, absorbability, ornamental property, tactile property, cost reduction, dimensional stability and the like.

Chemical foaming agents include inorganic foaming agents such as sodium bicarbonate (NaHCO ₃ ) and organic foaming agents such as ADAC, OBSH, TSH and the like. Most organic foaming agents are used. However, in the present invention, it is more preferable to add a sulfur-containing inorganic foaming agent in powder form in order to enhance the harmlessness of human body and promoting foaming. Particularly, when the amount is less than 0.6 parts by weight, the foaming property is deteriorated. When the amount of the foaming agent is more than 0.8 parts by weight, foaming is promoted by the foaming promoter described later I do not.

Meanwhile, Zinc P-Toluenesulfinate, which is a non-Urea-based promoter, is used as a foam promoter added to adjust the decomposition temperature and speed of the blowing agent to control the foaming so as to meet the process conditions of use, Is preferably in the range of 0.05 to 0.15 part by weight, considering that the foaming temperature of polystyrene or impact resistant polystyrene is from 100 to 180 ° C.

In the present invention, zinc is added to improve releasability, and the releasability of the zinc is such that the transfer paper transferred in the primary transfer step (S150) for slice transfer can be easily separated after fragmenting, The addition amount is preferably 0.05 to 0.15 parts by weight. Outside of the above range, the releasability is drastically lowered and the workability is deteriorated.

In addition, it is preferable to add a plasticizer in the present invention. Plasticizers are materials that increase the flexibility of a polymer, workability or extensibility of processing. Most of the plasticizers are an acid such as anhydrous fumaric acid, adipic acid, , And can be divided into two types, that is, externally digesting which is plasticized by mixing with a resin in a usual manner in nature, and internal digestion in which vinyl acetate or ethyl acrylate is copolymerized with ethyl acrylate or the like. These plasticizers function to increase the mobility of the polymer by relaxing the secondary intermolecular force of the polymer, thereby increasing the fluidity of the plastic by alleviating the intermolecular force between the molecules. Therefore, plasticizers should have compatibility with resins, but only a few plasticizers have one or more of the required properties and are often mixed.

In the present invention, it is preferable to use DOP which can be easily obtained by reacting phthalic anhydride with octyl alcohol in a liquid phase, and this DOP is uniform because the particle diameter is 0.3 탆 and is efficient.

On the other hand, it is preferable to add the plasticizer in an amount of 0.1 to 0.2 parts by weight. If the plasticizer is added in an amount of less than 0.1 parts by weight, the plasticization is drastically decreased and molding is difficult to produce. If the amount is more than 0.2 parts by weight, It is not preferable.

Finally, the far infrared ray or anion radiation composition added in the present invention is added in the form of a powder, and harmful substances such as formaldehyde and volatile organic compounds generated in the rods and building finishes are harmless Unlike existing environmental materials, which have a characteristic of decomposing into substances and have chemical action only when there is a certain amount of ultraviolet rays, it is possible to attach an inorganic metal material or an anion generating material which acts as an antibacterial and deodorizing material with a very small amount of light, It has the characteristic that it can remove material.

Meanwhile, such a far-infrared ray or anion-based composition can effectively prevent degradation of various harmful components including volatile organic compounds, cement toxicity blocking (blocking cement poison and dust such as hexavalent chromium, radon, ammonia and cold radiation) ), Anion emission (releasing a large amount of vitamin anion in the air to give strength to the cell and relieve stress), humidity control (keeping the dampness of the summer and the dryness of the winter suppressed to keep the stomach pleasant and fresh), far- (Such as far-infrared radiation, heat conduction is high and fast, and excellent heat-shrinking capability saves energy).

It is preferable that the far infrared ray or anion radiation composition contains at least two kinds of yellow loess, ilite, kaolin, elvan, feldspar, bentonite, sericite, crustacean, zeolite and diatomaceous earth. .

Detailed examination of the constituent minerals of the far infrared ray or anion radiation composition used according to the present invention reveals that loess is mainly composed of fine sand having a large amount of calcium carbonate and has a break point which is not easily broken by calcium carbonate, When water is added, it changes into clay. The loess also contains quartz, feldspar, mica and calcite, and these substances are oxidized together with iron and show colors such as yellow, purple, red, gray and green.

As for the various effects of the yellow loess, yellow loess releases far-infrared rays beneficial to the human body due to heat or natural light, and contains various beneficial ingredients to remove odors and waste materials, and neutralizes the lipid peroxidation Diluted to improve the constitution and suppress the aging function. In addition, due to heat transfer by radiation heating, the sensation temperature is high even at a low temperature, and when the far-infrared ray is absorbed by the human body, resonance (resonance) action and self heat generation phenomenon can be expected and an energy saving effect of about 30% can be expected. And it emits moisture when it is dried, and it is excellent in humidity control function.

Ilite is a fine clay mineral (usually 2 to 4 μm or less) in clay size and is a clay mineral with a plate-like structure similar to ordinary muscovite. The chemical composition of the clay minerals in the sediments is smaller than that of muscovite (K) and aluminum (Al), but the silicon (Si) and water (H ₂ O) , But since it has a slightly different chemical composition, structure and state of production from muscovite, it is named "Ilright".

In other words, this ilite is a clay-like soft mica mineral and is a scaly three-layered structure. When it is dissolved in water, it has unique properties indicating silk phenomenon. Its main components are silicon dioxide (SiO ₂ ), alumina (Al ₂ O ₃ ) It is a yellowish white synthetic mineral composed of potassium (K ₂ O), iron oxide (FeO ₂ ), etc. Its physical and chemical properties are the effect of dissolving a large amount of dissolved oxygen in water and the heavy metal ions, And the adsorbability is exhibited in the air and can be used as a raw material for a toxic gas and a malodor removing agent. In addition, Illight contains more than 150ppm inorganic germanium, which has the effect of promoting metabolism of human body.

Kaolin kaolin, and reungto, whiteness Sat (白陶土: china clay), also known as, and its main component is kaolinite _{(Al 2 O 3 · 2SiO 2} · 2H 2 O) , and halloysite _{(Al 2 O 3 · SiO 2} · 4H 2 O). Feldspars, such as feldspar, quartzite, soda feldspar, and feldspar, in the rock are produced by weathering, which is chemically decomposed by carbonic acid or water. A thick layer of several meters was developed on the rock of the original clay soil, and it was used as a raw material of ceramics and it was called "Goryeong" because it was produced in Gaolin of China.

In Korea, it is often called white soil. It is well known that many high quality clay is produced in the Hadong region of Gyeongsangnam-do and the far-infrared ray is reflected in a large amount.

Quartz and Quartz belong to the granodiorite of the igneous rocks, and the main components are silicic anhydride and aluminum oxide and contain a small amount of 2 iron oxides. On the other hand, the elvan is composed of 3 to 150 thousand holes per cm 3, and has a strong adsorption property. It contains about 25,000 inorganic salts. It is also used as a harmful metal removing agent through the action of exchanging ions with heavy metals. Therefore, it is used in various industries such as medical equipment and tableware.

Looking at the feldspar, the chemical composition of the feldspar contains the major constituents of the granite including potassium (K), sodium (Na), calcium (Ca), barium (Ba), aluminum (Al) , And the feldspar produced naturally is classified into a series of three end components such as potassium feldspar, sodium feldspar and calcium feldspar. When the feldspar is heated, it emits a large amount of far infrared rays beneficial to the human body, It is known that indoor air can be improved by an antifungal effect and the like. In addition to being able to adsorb and neutralize surrounding toxic substances by the adsorption effect of minerals on the feldspar, the clay minerals have a strong anion substitution ability to make the artificial stone plates harmless to the human body. It can be used as raw material.

Bentonite is a montmorillonite based clay. It contains many quartz, feldspar, zeolite, etc. It has white, gray, light brown color, pale green, etc. It absorbs water and swells, It is similar to montmorillonite in that it has a clear exchangeability. It can be used as a main component of petroleum refining mud water, as a binder of casting mold, as a binder for ceramic raw materials, and as a base for ointment. The bentonite is produced by removing crystal water in the ore by firing at a temperature of about 1000 to 1200 占 폚, and the apparent density is reduced by ejection of crystal water during firing, and the resulting large pore has heat insulation property.

Cerisite is a kind of clay minerals, which contains a carly (K ₂ O) and is also called a carly clay. Its color is silver-white, and it is called sericite because it shows strong silk luster. It belongs to mineralogical group of mica, and its chemical composition and crystal structure are similar to muscovite. Therefore, as a secondary mineral, its properties and performances are similar to those of moscovite and illite, which are close to those of intermediate light. These crystal structures are an essential element for improving and hardening the mechanical properties of the synthetic resin.

Cryptomeria is a natural mineral containing a large amount of hornblende in the elvan, and is a compound word of elvanite and hornblende. Far infrared rays of the absorption wavelength of the organic compound are radiated by 90% or more. All minerals were irradiated with far infrared rays. Especially, it was confirmed that the elvanite had more far-infrared radiation than other minerals. However, in order to benefit human and organic compounds, far infrared rays of 8 to 11 mu m should be emitted, and most of the minerals do not greatly affect the human body because the far infrared ray emissivity rapidly decreases at the human body and organic compound wavelength range. In order for the far infrared rays of this range to be radiated to a high degree, cementite containing austenite should be used appropriately. In addition to the far-infrared radiation effect described above, cementite has antibacterial and deodorizing effects.

The general chemical composition of zeolite ore is 65 ~ 73% of silica (SiO ₂ ), 10 ~ 15% of alumina (Al ₂ O ₃ ) 1 to 3% of potassium (K ₂ O), 1 to 3% of sodium oxide (Na ₂ O), 1 to 3% of calcium oxide (CaO), and 0.5 to 2% of magnesium oxide The ingredients are very small. Zeolite, a natural mineral harmless to the human body, is a fine-grained mineral with a micro-pore diameter of several Å in crystal structure and has many properties such as ion exchangeability, molecular sieve action, adsorptivity and catalytic property. In addition, zeolite is a highly mineralized material for soil remediation, water purification, livestock feed, tobacco filter, deodorant, environmental improvement, various pollution prevention, etc., and also has good adsorption to radioactive materials, . Since zeolite has a high adsorptivity and deodorizing effect, the zeolite can remove the odor and harmful gas in the room, and is widely used as a far infrared ray material.

Diatomaceous earth is a sedimentary rock formed by deposits on a lake or lake where a single-cell algae, which is commonly referred to as diatom, has died. The diatom is an algae with a size of 10 ~ 100 ㎛. It has many kinds of algae. It absorbs silicate in water to make a cell wall in its lifetime. The skeleton has many nano-sized micropores. Therefore, diatomaceous earth is a very dense material with a very small pore size, so it is light in weight and has various characteristics such as absorbency, adsorption, and sound insulation.

Diatomaceous earth is used in various fields such as filtration, additives (filler), absorbent, insulation, abrasive, carrier and catalyst. Diatomaceous earth is composed of silica with a large amount of micropores. It has low thermal conductivity, high melting point, low coefficient of thermal expansion, low shrinkage at high temperature, high resistance to thermal shock, . Because of these properties, diatomaceous earth containing clay minerals as an impurity is plasticized because it has a large adiabatic effect and it is molded and fired to be used as refractory insulation bricks for steelworks and incinerators.

In the present invention, it is preferable to add 3 to 5 parts by weight of the composition so that the characteristics of the Far Infrared ray or the anion protective composition can be fully utilized, and that the composition can be molded by molding while being foamed and plasticized.

When the blending is completed through the first raw material blending step (S100), the first raw material melting and foaming step (S110) is performed.

In this case, the melting temperature of the general-purpose polystyrene and the impact-resistant polystyrene is 100-180 ° C, and the foaming temperature is 145-170 ° C.

When the primary raw material is blended, it is introduced into the extruder to be melted by the high temperature inside the extruder, and the molten raw material is extruded into the mold by its own weight and rotation of the screw located inside the extruder.

At this time, when the extrusion temperature is 200 ° C or higher, the raw material is decomposed to change its properties. Therefore, the melting temperature is preferably maintained at 100-180 ° C.

The primary raw material melting and foaming step (S110) is a step of increasing the capacity by foaming the mixture with the foaming agent and the foaming promoter while heating the mixture to melt the mixture.

A secondary raw material blending and melting step (S120) for melting the secondary blended raw material composed of the primary blended raw material mixed with the impact resistant polystyrene as the material at a temperature of 100 to 180 ° C is carried out.

The impact resistant polystyrene used in the second blending is for smoothly coating the molding surface, and when this process is excluded, the molding surface is rough and the transfer can not be carried out, which is undesirable.

The foamed foam and the molten secondary compounding material are subjected to a molding step (S130) in which they are put into a mold provided for producing a molding and molded.

In the molding step, the foamed foam and the molten secondary compounding material are put into a hopper of a first extruder and a second extruder, respectively, and are extruded into a first die and a second die, respectively, And the second die is configured such that the extrudate forms an outer layer and the extrudate having the outer layer enclosing the inner layer is discharged, wherein the temperature of the cylinder of the first extruder is 100 to 140 ° C, The cylinder temperature of the extruder is set to 150 to 180 ° C.

After completion of the molding, the cooling step (S140) of purified water at 1 to 10 ° C is performed in the cooling bath so that the standard of the molded product can be stabilized.

After cooling, a first transfer step (S150) is carried out to apply a transfer paper for engraving to the surface of the molded preform. Since the soft resin constituting the outer layer of the extrudate has a specific gravity of 0.9 to 1, the film supplied by the upper and lower transfer film supply rolls is pressed against the front and back surfaces by the hot press roller, It is preferable that the temperature of the hot-press roller is 140 to 160 ° C.

In addition, a second transfer step (S170) is performed in which a sculpting step (S160) is carried out to form a pattern by being sculpted in accordance with the transferred form, and the sculpture is transferred again so as to have a final surface after the sculpture, do.

The polystyrene moldings can be manufactured by this manufacturing method, and various types of polystyrene moldings can be manufactured according to the molds to be molded.

Particularly, if the mold is held in the shape of a molding frame, a frame, a mirror frame, etc., the polystyrene molding according to the present invention can be used for interior moldings, frame frames, mirror frames, bathroom scaffolds, bathroom frames, furniture edges, A window blind, or the like.

Hereinafter, the present invention will be described in detail on the basis of embodiments. The presented embodiments are illustrative and are not intended to limit the scope of the invention.

[ Example ]

In order to confirm the characteristics of the polystyrene molding added with the far-infrared ray or anion radiation-curable composition prepared according to the present invention, test pieces were prepared using the blended raw materials in the composition ratios shown in Table 1 below.

The primary blended raw materials are melted at a temperature of 150 ° C and foamed at 160 ° C. At this time, the far infrared ray or anion protective composition was obtained by pulverizing yellow earth, ilite, kaolin, elvan, feldspar, bentonite, sericite, celesteite, zeolite and diatomaceous earth to a size of 0.05-1 mm.

3.5 parts by weight of impact resistant polystyrene was mixed with 100 parts by weight of the primary blended material to obtain a secondary blended material. The secondary blended material was melted at the same temperature as that of the primary melting, and the molten secondary blended material The primary molten and foamed foam and the extruder were extruded into a mold to form a mold. The melted and foamed primary blended raw materials and melted secondary blended raw materials were put into the hoppers of the first extruder and the second extruder, respectively. The cylinder temperature of the first extruder was set to 140 ° C. The cylinder temperature was set to be 180 DEG C so as to be extruded into the first dice and the second dice, respectively. In the present invention, the first die forms an inner layer of the extruded material, and the second die forms an outer layer of the extruded material, so that a molded product of a shape that surrounds the inner layer of the polystyrene resin foamed with the soft resin of the outer layer is discharged.

The discharged molded product was cooled by passing through a cooling bath at 7 캜 so as to stabilize the size of the molded product, and a first transfer step of transferring the transfer paper for the pieces to the surface of the preformed molding was performed. The film supplied by the transfer film supply rolls installed above and below was pressed against the front and back surfaces by a heat pressure roller so that the ink of the transfer film was infiltrated.

After the primary transfer, the secondary transfer was carried out by transferring the transfer paper so as to be finely processed according to the transferred pattern and shape, and finally to finish the engraved molding surface, thereby completing the polystyrene molding with the far-infrared ray or anionic composition.

Example 2 and Example 3 were the same as the production method of Example 1 except that the blended raw materials were blended in the composition ratios shown in Table 1 below.

In the case of the conventional material, as described in the prior art, there is no such characteristic at all, and in particular, harmful components are severely detected. Therefore, it is not necessary to mention composition and analysis for the conventional material.
