Description

[0001] METHOD AND SYSTEM FOR MANUFACTURING EXTRUSION SYNTHETIC RESINS FOR CONSTRUCTION [0002]

The present invention relates to a synthetic resin extrusion perforated panel for architectural use, which is used as a wood substitute, and can be used as an interior or exterior material for buildings, an interlayer sound absorber, a soundproofing material for walls, a flooring for salt floors, a gym floor, an office partition, a toilet partition, Double extruded perforated panel device and panel manufacturing method which can be used as interior material, double flooring, base of logistics warehouse, flooring of air and ship, floor of cargo truck, flooring of deck timber, .

Particularly, the present invention relates to a method of manufacturing a double extrusion panel in which a synthetic resin double extrusion panel is formed, the inner side is made of a waste synthetic resin and the waste synthetic resin outer layer is made of a new synthetic resin, Thereby improving the durability and tensile strength against impact resistance, moisture resistance, and, if necessary, forming a multi-layered extruded panel having a plurality of laminated portions on the outer surface of the double extruded panel .

Further, the extrusion panel of the multilayered structure has a plurality of holes in the form of a hollow part transversely to the inner center part made of waste synthetic resin. When forming a plurality of holes in the extrusion panel, The present invention also relates to an apparatus and a method for manufacturing a synthetic resin extrusion porous panel for a building.

In the past, building interior and exterior panels, container floors, pallets for logistics warehouses, and cargo truck flooring materials were made of wood. In addition, deck timber was used for resting floor, observatory to climbing books, and stairs.

As such, timber is a very important building material or flooring used in all industrial societies. In modern times, however, each country is limited in logging, resulting in insufficient supply of timber and rising prices. However, they are not able to find materials that are as good as wood.

In order to solve this problem, synthetic resin is selected as a substitute material for wood and molded by extrusion and extrusion. However, there is no problem with general household products when molding is made only with new synthetic resin. However, in construction interior and exterior materials, There is a problem in that the price of wood is higher than that of wood due to an increase in raw materials and manufacturing cost, and a problem that a building material product, which is replaced with a synthetic resin product, has poor elasticity and tensile strength.

  In addition, in order to have durability against shock absorption when molding a product using a conventional waste synthetic resin, there is a problem in that the efficiency of the waste synthetic resin is lowered by producing a monolithic product by mixing the PVC raw material with the waste synthetic resin, It is necessary to clean the soil on the collected waste synthetic resin and dry it again, so that the initial sorting operation is performed manually by hand, so there is a problem in that it is necessary to manage personnel as well as labor costs.

Therefore, the recycled products using waste synthetic resin are not activated for building products and civil engineering products, and some waste is mainly used in waste water pipes, sewage pipes and the like, and the remaining waste is incinerated, thereby increasing waste disposal costs.

Prior art of this field is disclosed in Korean Patent Registration No. 10-0789957 (registered on Dec. 21, 2007) entitled " Apparatus and Method for Producing Double Extruded Panels Using Waste Synthetic Resins " A production apparatus for extruding a building member or a bottom material by using a waste synthetic resin, comprising: a raw material for mixing raw materials of recycled PE crushed by a conventional crushing apparatus for collecting waste plastic waste vinyl and raw materials of wood, rice hull, vermiculite, A mixer (1);

When the raw materials mixed in the raw material mixer 1 are supplied to the hoppers 3 and 3 ', the raw materials are melted by the plate-like heaters 4 and 4' (2) and a second extruder (2 ') for extruding the extrudate (5) to the head part (6) or (6') side; The raw material extruded from the head portion 6 of the first extruder 2 is formed into the inner body 8 and the raw material extruded from the head portion 6 'of the second extruder 2' A double extrusion molding machine 7 having a plurality of rectangular blocks to form the synthetic resin panel 30 by adjusting the inflow amount of the external body 9 with the adjustment bolts 20 provided on the upper and lower sides,

A purge air 12 is provided inside the front surface so that the surface of the synthetic resin panel 30 formed by the double extrusion molding machine 7 composed of the plurality of rectangular blocks is smoothly smoothed and a plurality of guides 16 A cooler (11) provided with cooling water;

An ejector 17 having rollers 18 formed on both sides of the synthetic resin panel 30 so as to pull out the synthetic resin panel 30 cured by the cooler 11; And a cutter (19) for cutting the synthetic resin panel (30) drawn out from the drawer (17) so that the circular saw can be cut to a predetermined length while moving.

Since the prior art is a method in which the supply of the raw material supplied to the dice is pushed out to extrude the inner body and the outer body to extrude, an innumerable air layer is formed in the inner body of the waste synthetic resin and is extruded through the die in the state of gel, There is a problem in that the thickness of the discharged synthetic resin panel is not uniform according to the texture, and the core is partially formed.

Particularly, in the prior art, since the raw material of waste synthetic resin is supplied to the die in the state where it is melted in the extruder, it contains many air layers and the dense portion and the non-dense portion of the structure coexist so that the panel extruded from the die is pulled from the siphon to the vacuum In this process, a large amount of air layer is formed, and since the structure is not uniform, the shrinkage density becomes different as a result of being cooled after vacuum, so that the thickness of both side edges and the central part are not uniform, .

That is, even if the inner synthetic resin is melted in the extruder, it is not formed in a liquid state like a new synthetic resin but is formed like a soft and fluffy rice cake, so that a core is formed at the time of extrusion and the extrusion speed is slow.

Even if the waste synthetic resin is melted by heating in an extruder, if the temperature is increased excessively, it is not melted but burned. Therefore, the waste synthetic resin has a different physical property from that of the new synthetic resin. Therefore, when pure synthetic resin such as waste vinyl, And is extruded into a die by the pressure output of the extruder in the same state as a soft rice cake when it is transferred to the die, so that there is a problem that the inner layer has a different melting point from the air layer.

In addition, since the prior art does not form a hollow portion at the center of the inner body when the double panel is formed, there is a problem that the weight becomes large and the tensile strength decreases.

In addition to the above-mentioned prior arts, the prior art of this field described above includes Patent Registration No. 10-1068947, Patent Registration No. 10-1166899, Patent Registration No. 10-0534050, Patent Registration No. 10-0645935 . However, the above-described prior arts have the same problems as described above, and thus, they are not continuously produced. Particularly, in the prior art and the conventional double extrusion panel molding apparatus using waste synthetic resin, The extrusion speed is so low that the productivity of the double extruded panel is remarkably reduced due to the fact that the sieve is extruded from a single die (extrusion die) using a new synthetic resin.

In addition, when the inner body and the outer body are combined, gas and moisture are extruded between the inner body and the outer body, so that there is a problem that the inner body and the outer body of the double synthetic resin produced later are lifted.

In the prior art described above, the new synthetic resin is referred to as the external body and the waste synthetic resin is referred to as the internal body. However, in the present invention, the internal body will be referred to as an internal molded body and the external body will be referred to as an external molded body.

A process for manufacturing steps of a synthetic resin extrusion panel molding apparatus 100 having a multilayer structure according to the present invention will be described.

Step 1: Blending of raw materials and feeding step

The raw materials used in the present invention are roughly classified into two types. The waste synthetic resin constituting the inner molded body A and the raw material synthetic resin constituting the outer molded body B are separately prepared.

The inner molding (A) is a waste synthetic resin. The outer molding (B) is composed of a plastic for mulching and a plastic bag, which are generated after cultivation of crops in farming and fishing villages, .

The waste vinyl or waste synthetic resin, which is the raw material of the inner molding (A) of the present invention, is not crushed and subjected to a separate washing process, but is used as it is, even if soil or wood pieces are mixed.

The raw materials for the internal molding (A) used in the present invention are collected at random in agricultural and fishing villages and industrial sites, and can be broken by drying and crushing. However, through the sorting machine equipped with magnets, the metals are sorted, separated, Vinyl and the like are crushed together and used as a raw material for the inner molding (A).

The waste synthetic resin material thus prepared is dried by the hot air blowing from the heat supply fan of the heater unit in the raw material mixture feeder 200, and then is supplied to the first extruder 300 by the discharge conveyor.

At this time, a raw material for synthetic resin is prepared in another raw material mixture feeder 200 and supplied to the second extruder 301.

The raw material compounding feeder 200 for supplying the waste synthetic resin to the first extruder 300 and the raw material compounding feeder 200 for supplying the second raw material synthetic resin to the second extruder 301 are installed in the same configuration . Therefore, in the present invention, the reference numerals of the raw material mixture feeder 200 are described by the same numbers.

A heater device having a hot air supply fan is installed at one side of the raw material mixing feeder 200, and the raw material in the main body is installed to be dried by hot air.

The dried raw material is supplied to the primary extruder 300 or the secondary extruder 301 by a discharge conveyor installed in the raw material mixing feeder 200.

Second step: raw material extrusion step

A plurality of raw material mixing feeders 200 are provided so that one raw material mixing and feeding device 200 is connected to the primary extruder 301 so as to be melt-extruded, and the other one of the raw material mixing and feeding devices 200 ), The new synthetic resin is sent to the second extruder 301 for melt extrusion.

The extruder used in the present invention uses an extruder for melt-extruding a synthetic resin. The control part is configured to electrically control the driving part and the heater on one side, the hopper is formed on the raw material input part of the extruder, and the synthetic resin A plate type heating device 310 is installed on the outer surface of the screw so as to melt the synthetic resin material conveyed by the conveyance screw.

The plate-type heating device 310 installed in each of the extruders is installed in proportion to the screw length of the extruder, and the heating temperature of the plate-type heating device is set so that the temperature can be set differently for each section.

The outer surface of the plate-type heating apparatus 310 thus formed is formed so as to prevent a safety accident of the operator from being formed.

The extruder used in this process is provided with a primary extruder 300 and a secondary extruder 301. The primary extruder 300 allows the waste synthetic resin to be melted and supplied to the primary die 400, The extruder 301 can supply the primary dies 400 so that the new material synthetic resin is melted and stacked and double-extruded.

The primary die 400 is installed to receive the melted resin from the primary extruder 300 and the secondary extruder 301, which are supplied with the raw material of the synthetic resin and the raw material of the synthetic resin from the respective raw material mixing feeders.

Step 3: Double extrusion molding of primary resin into primary dies

The waste synthetic resin introduced from the primary extruder 300 flows into the primary die 400 through the inner molding injection port 401 formed on the rear surface of the primary die 400.

The primary die 400 is extruded and conveyed in a state of a trumpet tube at one of the inner molding injection openings 401 on the front side and filled with molten waste synthetic resin into the inner molding extrusion line 403.

The discharge port side of the primary extruder 300 is connected to the inside injection port 401 of the primary side of the primary die 400 and the inner injection port 401 of the primary die 400 is connected to the internal molded body extrusion path 403 And is formed so as to extrude the inner molded body A.

A plurality of hemispherical protrusions 410 are formed on the inner peripheral surface of the inner molded body extrusion path 403 of the primary die 400 so that the inner formed body A to be extruded is untied and loosened, (A) is extruded to remove bubbles and to subdivide the particles to prevent the formation of agglomerates.

 In addition, a resin inflow amount regulating device 440 is installed on the entire inner surface of the inner molding extrusion path 403 of the primary die 400 to uniformly extrude the amount of the resin introduced into the inner molding extrusion path 403 using bolts from the upper side .

The waste synthetic resin introduced into the inner molding extrusion path 403 of the primary die 400 through the primary extruder 300 is formed on the inner peripheral surface of the primary die 400 which is extruded from the inner molding extrusion path 403 And it is operated like dough in the process of repeating the operation of loosening and loosening when extruded by the plurality of hemispherical protrusions 410, thereby preventing the air layer in the waste synthetic resin and finishing the tissue to prevent the core from being formed inside the waste synthetic resin.

The inner wall of the primary die 400 has a plurality of hemispherical protrusions 410 formed on the slope of the inner die 401 and the primary die 400 The diameter of the hemispherical protrusion 410 gradually decreases.

 This is because the waste synthetic resin introduced into the primary dies 400 is formed in such a manner that the hemispherical protrusion 410 gradually decreases from the inlet to the discharging portion 420 in order to smoothly perform the operation at first, During the process of passing the waste synthetic resin through the inner molded body extrusion path 403 of the primary die 400 as if the stomach is digested, the air remaining in the waste synthetic resin is discharged to the outside And the structure becomes fine and the fine grains are formed, so that no dullness is generated on the outer surface of the subsequently formed panel, and the durability can be improved.

The primary die 400 has a configuration in which a plurality of rectangular blocks are combined and a plate-shaped heating device 310 having a plate shape is installed on the outer surface thereof.

Inside the primary die 400, an inner molded body extrusion path 403 is formed to allow the waste synthetic resin to be passed through while being extruded, and a secondary extruder 301 is connected to one side of the intermediate die of the primary die 400, The synthetic resin is doubly superposed on the outer surface of the inner molded body A of the waste synthetic resin extruded from the inner molded body extrusion path 403 of the primary die 400 to be connected to the molded body injection port 402, do.

The secondary extruder 301 has the same constitution as the primary extruder 300 and supplies the raw material for synthetic resin to the raw material synthesis feeder 200 separately provided as in the primary extruder 300, 400 and is extruded in the extruded external extrusion path 404 to be superimposed on the outer surface of the internally formed body A of the extruded water to form the discharge part 420 of the primary die 400, And then flows into the primary syringe 700.

Step 4: forming a plurality of hollow holes in the double extrusion panel

The synthetic resin extrudate extruded through the primary die 400 may be formed without forming the hollow hole 22, but a plurality of hollow-shaped holes 22 may be formed in order to increase strength and provide durability and tensile strength .

In order to form the plurality of holes 22, a pipe-shaped hole forming die 600 having a hollow portion is inserted into the coupling hole 423 formed in the partitioning wall 421 of the discharge portion 420 of the primary die 400 To be installed.

At this time, the hole forming rod 600 is connected to the air hole 430 transversely formed inside the discharging portion 420 side of the primary die 400, but is installed in an intersecting direction.

The hole forming rod 600 is installed to be detachable from the coupling hole 423 formed in the partitioning wall 421 of the discharge part 420.

The hole forming rod 600 is in the shape of a pipe and has an internal hollow portion so that the air supplied from the air supplying portion 500 provided at one side of the primary die 400 passes through the air hole 430, The air is blown into the primary sizing 700 in which the distal end of the hole forming rod 600 is located to cool the hole 22 of the inner molded body A to be extruded.

The inner and outer molded bodies A and B discharged from the discharge portion 420 of the primary die 400 are separated from each other by the divisional partition wall 421 of the discharge portion 420 in a polymerized state, And then discharged through the primary siphoning unit 700. [0051] As shown in FIG.

Since the extruded material is discharged from the discharging portion 420 in a state that the extruded material is blown up and down in the overlapped state after the inner molded body A and the outer molded body B are extruded from the primary die 400, A plurality of hole forming rods 600 provided between the discharging portion 420 of the primary die 400 and the primary sieving 700 have a side portion Exposed state.

A plurality of hole forming rods 600 provided between the discharging unit 420 of the primary die 400 positioned in the space unit 40 and the primary sining unit 700 are connected to the air supplying unit 500 The air injection nozzle 510 is installed to inject air from one side of the space portion 40 to the other side so that the internal molding A and the external molding B are polymerized and the primary sieving 700) inlet, the moisture and gas existing between the upper and lower extruded products are dried by air, so that they are introduced into the primary siphon 700 and vacuumed to remove the air layer and moisture during the extrusion, The inner molded body A and the outer molded body B of the subsequently molded double synthetic resin extrusion panel are prevented from spreading and are firmly adhered to each other to have durability.

In addition, the present invention can increase the production rate by increasing the extrusion speed of the extrusion panel by injecting air into the hole forming rod 600 and the space portion 40.

The double synthetic resin extrusion panel of the present invention is characterized in that a hole forming rod 600 is horizontally installed in a coupling hole 423 formed laterally in the partitioning partition wall 421 of the primary die 400 discharge part 420, A plurality of holes 22 are formed in the extruded molded product A of the extruded product from the extruder 400.

The plurality of holes 22 formed in the inner molding of the extrudate are formed into a circle, a square, a triangle, a rectangle, an ellipse, or the like depending on the shape of the hole forming rod 600.

Step 5: Primary Sizing Step for Vacuum Forming

The extrudate of the double synthetic resin extrusion panel in which the plurality of holes 22 are formed by the hole forming rod 600 provided in the partition wall 421 of the primary die 400 discharging portion 420 is subjected to primary sieving 700 ) So that the outer surface of the panel is flat and smoothly formed.

The primary sizing 700 for vacuum molding has a space such as a tunnel to allow the extrudate of the double synthetic resin extrusion panel to be drawn into the other side and a plurality of vacuum holes are formed therein, The extruded material of the extruded panel is sucked and vacuumed to make the outer surface smooth.

At this time, the primary syringe 700 for performing vacuum molding is formed of one unit, and a partition 710 is formed at a position 1/3 from the inlet so as to be divided into a first vacuum chamber 720 and a second vacuum chamber 730 Respectively.

In the primary sizing 700, a vacuum is applied to the extruded material in the primary die 400 to weaken the surface of the molded product 600 immediately after the extrudate is removed from the molding die 600 in the primary syringe 700 The vacuum pressure is increased while passing through the second vacuum chamber 730 so that the hole 22 formed in the extrudate and the overall shape are fixed.

In the present invention, when a new synthetic resin is used in the extrusion molding of a panel using a synthetic resin, holes 22 formed therein are formed without being deformed at the time of extrusion. However, when the waste synthetic resin is used, The primary syringe 700 is divided into a first vacuum chamber 720 and a second vacuum chamber 730 and vacuum is applied to the first vacuum chamber 720 and the second vacuum chamber 730. As a result, A square, a rectangle, an ellipse, or the like is formed so that deformation does not occur during molding.

In the present invention, the partition 710 is formed in the primary sintering 700 to divide the primary vacuum 720 and the secondary vacuum 730 into vacuum holes, However, since the extruding speed of the waste synthetic resin is slow, the vacuum pressure in the primary syringe 700 weakens the primary vacuum 720 and the vacuum pressure in the secondary vacuum 730 is high The extrusion speed at which the panel is moved can be made faster and the productivity can be increased.

Further, the inlet of the primary syringe 700 has a wide front surface and a narrow rear surface so that the panel extrudate conveyed from the primary dies 400 can be easily introduced into the primary syringe 700 The inclined surfaces 740 are formed in the upper, lower, left, and right sides to facilitate the inflow of the extruded panel.

  At this time, when the extrudate extruded from the primary die 400 is introduced into the primary sieving 700, it must be pulled in a consolidated form when it is filled in the inlet, so that the primary sieving 700 forms a vacuum-type panel, And the inlet of the primary syringe 700 is formed as the inclined surface 740, so that the extrudate is smoothly flowed while being consolidated when it is introduced.

In addition, since the primary discharger 920 installed at the rear of the primary syringe 700 is pulled in a consolidated form at the entrance of the primary syringe 700, the primary syringe 700 is consolidated at the entrance of the primary syringe 700 along the inclined surface 740, ≪ / RTI >

The primary syringe 700 has a channel formed around the vacuum hole to circulate refrigerant to cool the syringe body.

Step 6: Primary vacuum cooling molding and water-cooling step

The smoothed extrudate from the primary siphon 700 has a panel shape and is passed through a primary vacuum cooler 800 so as to be fixed and cooled so that no deformation occurs during the cooling process.

 The primary vacuum cooler 800 is installed at the head of the primary water cooling apparatus 900 having a chamber shape and is configured such that the shape of the primary extrusion panel 20 which is the extrudate to be extruded and delivered from the primary sintering 700 is deformed So that it is cooled in a vacuum.

That is, since the panel extrudate passes through the primary sintering 700 and the external shape is formed by the first extrusion panel 20, but since the cooling is not completely performed, the first vacuum cooler 800 and the first- And is completely hardened by the cooling device 900 to prevent the outer shape from being deformed.

The primary vacuum cooler 800 is composed of upper and lower cooling plants 810 and 811 and the upper cooling plant 810 is configured to be moved up and down by a cylinder.

Further, the upper and lower cooling platforms 810 and 811 have a vacuum hole formed on the bottom surface thereof, so that the synthetic resin double panel conveyed to one side does not interfere with movement and performs adsorption and cooling so that deformation does not occur during cooling.

At this time, the vacuum in the primary vacuum cooler 800 is weakened to be completely fixed so that deformation does not occur in the shape and cooling is performed by the refrigerant of the primary vacuum cooler itself.

As described above, the first extrusion panel 20, which has been cooled first while maintaining the smoothness in the first vacuum cooler 800, is placed in a state of being immersed in water by a plurality of moving rollers 901 installed in the first water cooling apparatus 900 Move.

In this case, when the primary water cooling device 900 is provided with an aeration device at one side of the water tank, air bubbles are generated in the water, and when the water is vibrated, a large number of air bubbles come to the top in the water tank, .

When water is filled in the primary water cooling apparatus 900 and the water is cooled, a partition is provided so as not to interfere with vacuum being generated in the primary vacuum cooler 800 installed at the front end, so that the primary vacuum cooler 800, The cooling device 900 is separately installed so that the primary vacuum cooler 800 is not disturbed by water.

In this process, the double synthetic resin extrusion panel 21 of the primary extrusion panel 20, which has passed through the primary water cooling apparatus 900, is cured to form a complete panel.

That is, since the primary extruded panel having passed through the cooling water is completely cooled and no further deformation occurs, it can be cut into a predetermined standard and used as the double synthetic resin extrusion panel 21. [

The panel passed through the primary water cooling device 900 in this way is referred to as the primary extrusion panel 20 in the present invention.

Step 7: Dewatering and withdrawing of the outer surface of the panel

The water sprayed on the surface of the first extrusion panel 20 which is water-cooled by the primary water cooling device 900 is removed by the air injection device 910. [

Since the surface of the primary extrusion panel 20 cooled by the primary water cooling apparatus 900 is in a wet state with water, external moisture must be dried for a subsequent process, and the air is then dried by the air injection device 910.

A first blower 920 is provided on the same line behind the air injection device 910 so that the synthetic resin supplied from the first extruder 300 and the second extruder 301 passes through the first die 400, The first vacuum chiller 800, the primary water cooling apparatus 900, and the air injecting apparatus 910 in this order. At this time, the extrudate is discharged to the discharge part 420 of the primary die 400 by the pressing force of the primary extruder 300 and the secondary extruder 301 and the pulling force of the primary extruder, (700), it is moved only by the pulling force pulled from the first deliverer 920.

If the first extrusion panel 20 is completed and the second extrusion panel 20 is to be used as the second extrusion panel 21, the cutter 1300 is installed in the next step of the first extruder 920, The double synthetic resin extrusion panel 21 can be formed.

At this time, the finished panel is formed with the inner formed body (A) made of waste synthetic resin at the center, and the outer molded body (B) made of the synthetic resin is polymerized on the outer surface.

The panel made in the above process can mold a panel of 10t, 12t, 15t or the like. Of course, the thickness of the double synthetic resin extrusion panel molded according to the present invention may vary according to the hole size of the primary sizing, and it is possible to produce a panel by selecting it at the time of manufacturing.

If the thickness of the panel is to be more than 20t, 24t or the like, the surface of the primary extrusion panel 20 cooled through the primary water cooling device 900 is in a wet state, The outside water is dried by the air jetting device 910 and at the same time the primary dispenser 920 is pulled and sent to the heating chamber 930.
