Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a door made of a polystyrene resin material,

The present invention relates to a door made of a polystyrene resin material which is easy to dispose of waste. By using polystyrene resin as an eco-friendly material for all materials, it is possible to recycle by separating only the door at the time of waste treatment. And a frame finishing material bonded to a rim portion of the surface material. 2. The method according to claim 1, wherein the surface finishing material is a finishing material. To a door made of a polystyrene resin material which is easily processed.

Generally, a wooden door manufactured by processing wood is weak in moisture, causing problems such as twisting or rotting during use, and there is a drawback that durability is very weak. Accordingly, recently, a synthetic resin door which is resistant to moisture, has little corruption and corrosion, and has excellent durability has been developed and replaced with a wooden door.

The synthetic resin door typically has an outer core member of a rectangular frame structure constituting the outer framework of the door, an inner core member vertically disposed on the left and right inner sides of the outer core member, a filler filled in an inner hollow space of the inner core member, An inner core member and a pair of synthetic resin surface members that are attached to the filler material and constitute both front and rear surfaces of the door.

FIG. 1 is a front view of a conventional synthetic resin door, and FIG. 2 is a cross-sectional view taken along line AA in FIG. 1.

Here, in the synthetic resin door according to the prior art, the outer core member 2 foamed by PVC is used as an outer structural member, the inner core member 3 made of wood is positioned inside the outer core member 2, (3) was filled with a filling material (4) such as paper honeycomb or styrofoil, and then an adhesive was applied to the front and rear surfaces of the synthetic resin surface material (1).

Generally, wooden doors such as wooden doors and veneer doors weigh 20 ~ 30kg per door (there is heavy weight). However, the synthetic resin door, especially the ABS resin, which is vacuum molded to form the surface member 1, has a weight of 12 to 15 kg per pair, which is relatively light and does not have a heavy weight (heavy)

An inner core 3 is coupled to the inside of the outer core 2 for the purpose of preventing twisting of the door. Unlike the outer core 2 using ABS resin, the inner core 3 is made of wood This is where the handle is installed. As described above, the conventional synthetic resin door requires an inner core 3 in addition to the outer core 2, and the inner core and the outer core are made of different materials so that they must be separated at the time of waste treatment, There was a problem.

Since the inner and outer core members 2 and 3 and the filler member 4 in the synthetic resin door according to the prior art are limited in their own various appearance, The inner core member 3 and the filler material 4. The surface member 1 is different in material from the material to be adhered, so that there is a difference in the elasticity according to the temperature change. As a result, , There is a problem in that the contraction and expansion are repeated according to the temperature change in the summer season, thereby causing separation or interference with the door frame.

On the other hand, the use of EMDF plywood as a door material has the advantages of easy processing and easy fabrication, but it is very vulnerable to moisture and is susceptible to damage by eating moisture, and harmful substances such as formaldehyde are generated in adhesives and paints, In particular, since the interior materials used for new buildings and apartments use chemical materials, adhesives, paints, etc., harmful gases such as formaldehyde are released into the air to cause headaches and dizziness. It is necessary to provide a deodorant, an anion generator, and the like in order to keep the air comfortable and to remove harmful substances harmful to the human body. However, in addition to purchasing a separate deodorant and anion generator, Separate < RTI ID = 0.0 > There is a problem that must be secured between.

The present invention has been proposed in order to solve all of the above problems, and it is an object of the present invention to provide a method of manufacturing a door by using the same material made of polystyrene for all the parts constituting the door, There is a first purpose to make it possible to recycle without separating parts by part.

In addition, the outer core member is used as the outer structural member without the inner core member, but is formed so as to use the polystyrene resin and formed so as to form the handle portion, thereby improving the weight feeling (heavy durability) and improving the bending strength and structural strength The second purpose is to make it better.

In the present invention, the flat plate molding of the polystyrene resin material, which is the same material as the rest of the materials, is used as it is without using different materials such as the MDF laminate as the surface material, and various shapes can be produced, It is a third object of the present invention to prevent the door frame from being disturbed or disturbed even if the expansion and contraction is repeated according to the change of temperature in the east and the summer.

Lastly, the present invention provides an environmentally friendly door in which all parts of the present invention are mixed with charcoal powders evenly and then melted and extruded to release far infrared rays, which are harmful to the body without releasing harmful substances such as formaldehyde There is a fourth purpose in doing so.

To achieve the above object, in the present invention,

On the other hand, charcoal has excellent preservative effect and numerous fine holes in the inside, and it has powerful adsorption and purification function against harmful gas such as formaldehyde and odor, and also has a humidifying ability to suck and discharge moisture according to the surrounding humidity.

In addition, charcoal helps relieve stress and emotional stability, strengthens the immune system such as intestines and liver, purifies blood, and generates negative ions that activate the body. It is rich in minerals, which are essential minerals for the human body. It has the effect of emitting far infrared rays by removing electromagnetic waves generated from electric appliances such as televisions or telephones used every day.

Far infrared rays are absorbed by the human body with long wavelengths of infrared rays, which are invisible heat rays. They cause vibrations in molecular units and generate heat energy, thereby promoting expansion of peripheral capillaries and promoting blood circulation. Excretes toxins, such as waste, and transports nutrients and oxygen.

Charcoal is also effective in the treatment of diseases, so in the civilian tradition therapy, it has taken the soot attached to the bottom of the cottage with leprosy or taking the sooty charcoal powder with the pine tree. In modern medicine, medicinal charcoal is prescribed as a remedy in the pharmacopoeia, so that it can be used as a remedy in the medical field. It is also prescribed by the Japanese Pharmacopoeia, and the activated charcoal is recognized as a medicine in the US Pharmacopoeia.

The synthetic resin parts used in the present invention, that is, the outer core 20, 30, the bracket 40, and the frame finishing 30 are all obtained by mixing and firing polystyrene resin powder with charcoal powder, And then the mixture is uniformly mixed with the polystyrene resin, and then melted and extruded to provide an environmentally friendly door that does not emit harmful substances to the human body.

The method of manufacturing various parts by melting and extruding polystyrene resin basically consists of (1) raw material blending, (2) melting, (3) extrusion, (4) cooling, (5) ,

EXPORTED POLYSTYRENE and HIPS (HIGH IMPACT POLYSTYRENE) were mixed in a ratio of about 1: 3, and mixed with 100 parts by weight of the entire raw material so that they accounted for 90 to 99 parts by weight, and 0.01 part by weight of citric acid 0.01 0.001 to 0.2 part by weight of zinc, 0.2 to 2.5 parts by weight of foaming agent, 0.01 to 0.2 parts by weight of peroxide and 0.002 to 0.2 part by weight of pigment are mixed, wherein EPS (EXPENDED POLYSTYRENE) , HIPS (HIGH IMPACT POLYSTYRENE) function to strengthen the impact strength.

When the raw material is blended, it is put into an extruder to melt by the high temperature inside the extruder, and the molten raw material is extruded into the mold by its own weight and the screw located inside the extruder rotating.

At this time, when the extrusion temperature is higher than 200 ° C., the raw material is decomposed to change its properties. Therefore, the melting temperature must be maintained at 150 to 180 ° C.

In addition, citric acid is used to powder the particles, zinc is used to increase the thermal conductivity, foaming agents are used to foam the raw materials, peripheries are for coloring, and pigments are used for the beauty of the aesthetic. Mixed by the number.

When the molten raw material is supplied into the mold, it is immersed in water and quenched to completely solidify the viscous liquid to complete the basic molding process.

In this way, the molding of the basic form is transferred to a mold called a HOT STAMPING FOIL, which can transfer various colors or insert the pattern through a piece transfer. By cutting it to a suitable size It is possible to complete various door parts.

According to the present invention, the melting process is carried out during the door component manufacturing process of the polystyrene resin material for a second time, and the raw materials used in the first and second melting processes are different and the charcoal powder is supplied at a predetermined ratio. Molding.

That is, in the present invention, EPS (EXPENDED POLYSTYRENE) as a synthetic resin material is mixed in an amount of 15 to 35 parts by weight with respect to 100 parts by weight of the total mixture and 60 to 85 parts by weight of HIPS (HIGH IMPACT POLYSTYRENE) , And in the secondary compounding and melting process, GPPS (GENERAL PURPOSE POLYSYTYRENE) is mixed with 0.5 to 2.5 parts by weight with respect to 100 parts by weight of the whole mixture and melted to form a smooth, high-quality texture of the finished part .

The second raw material, GPPS (GENERAL PURPOSE PS), is used to smoothly coat the molding surface. If this process is excluded, the surface of the door part becomes rough and it can not be transferred.

Further, the charcoal powders are mixed during the two times of the melting process of the synthetic resin material, and are mixed at a weight ratio of about 2: 4: 6 to 8 at one time and two times, respectively, so that they are extruded . There has been a phenomenon that the charcoal particles themselves are over-foamed due to the characteristics of charcoal, which always keeps moisture, and the foaming agent, when the charcoal is added only when mixing the primary raw material, and the surface of the door part is expanded. When the charcoal powder was introduced, the powder could be extruded without deforming its shape.

The present invention can provide an environmentally friendly door in which natural charcoal is powdered and mixed uniformly in a polystyrene resin material and then molten and extruded so that harmful substances are not released to the human body. The door parts are made of polystyrene resin material , The polystyrene resin material is melted twice, and at the second melting, GPPS (GENERAL PURPOSE POLYSYTYRENE) is mixed with 0.5 to 2.5 parts by weight with respect to 100 parts by weight of the whole mixture and melted, The surface is smooth and can form a high quality texture.

Examples and comparative examples are as follows.

Example  One

Firstly, 75 kg of EPS (EXPENDED POLYSTYRENE), 225 kg of HIPS (HIGH IMPACT POLYSTYRENE), 300 g of citric acid, 350 g of zinc, 0.001 to 0.2 part by weight of zinc foaming agent, 2.2 kg of zinc foaming agent, 25 g of a yellow pigment, 35 g of a brown pigment, and 3 kg of charcoal powder are uniformly mixed and then introduced into a compressor to be melted by the internal temperature of the compressor (maintained at about 150 ° C.).

Secondly, 7 kg of GPPS (General Purpose PS) 3KG and charcoal powder are melted, and the melted raw material is extruded into a mold through an extruder to form a molding.

The moldings thus prepared were smoothly coated on the surface, and afterward, the transfer was performed well, so that a feeling of luxury could be expressed. In addition, since the charcoal powder was not foamed and the molding surface was not inflated at all, molding could be made without deformation.

Example  2

Firstly, 90 kg of EPS (EXPENDED POLYSTYRENE), 200 kg of HIPS (HIGH IMPACT POLYSTYRENE), 300 g of citric acid, 350 g of zinc, 0.001 to 0.2 part by weight of zinc foaming agent, 2.2 kg of zinc foaming agent, 25 g of a yellow pigment, 35 g of a brown pigment, and 3 kg of charcoal powder are uniformly mixed and then introduced into a compressor to be melted by the internal temperature of the compressor (maintained at about 150 ° C.).

Secondly, 7 kg of GPPS (General Purpose PS) 4KG and charcoal powder is melted and the melted raw material is extruded into a mold through an extruder to form a molding.

The door parts thus manufactured were smoothly coated on the surface, and afterward, the transfer was performed well, so that a high-quality feeling could be expressed.

In addition, since the charcoal powder was not foamed and the molding surface was not inflated at all, molding could be made without deformation.

Comparative Example  One

Firstly, 75 kg of EPS (EXPENDED POLYSTYRENE), 225 kg of HIPS (HIGH IMPACT POLYSTYRENE), 300 g of citric acid, 350 g of zinc, 0.001 to 0.2 part by weight of zinc foaming agent, 2.2 kg of zinc foaming agent, 25 g of a yellow pigment, 35 g of a brown pigment, and 3 kg of charcoal powder are uniformly mixed and then introduced into a compressor to be melted by the internal temperature of the compressor (maintained at about 150 ° C.).

Secondarily, 7 kg of charcoal powder is melted by addition, and the melted raw material is extruded into a mold through an extruder to form a molding.

The door component thus manufactured has a problem that the surface thereof is very rough, and the transfer is difficult afterwards.

On the other hand, since the charcoal powder was not foamed and the surface of the door part did not expand at all, molding could be produced without deformation.

Comparative Example  2

Firstly, 75 kg of EPS (EXPENDED POLYSTYRENE), 225 kg of HIPS (HIGH IMPACT POLYSTYRENE), 300 g of citric acid, 350 g of zinc, 0.001 to 0.2 part by weight of zinc foaming agent, 2.2 kg of zinc foaming agent, , 25 g of a yellow pigment, 35 g of a brown coloring agent and 10 kg of charcoal powder are uniformly mixed and then introduced into a compressor to be melted by the internal temperature of the compressor (maintained at about 150 ° C.).

Secondly, GPPS (GENERAL PURPOSE PS) 3KG is added and melted, and the melted material is extruded into a mold through an extruder to form a molding.

The moldings thus prepared were smoothly coated on the surface, and afterward, the transfer was performed well, so that a feeling of luxury could be expressed.

However, the charcoal powder has the problem that the charcoal particles themselves are over-foamed due to the property of dampening the moisture and the effect of the foaming agent, and the molding surface expands.
