Description

Inorganic composite extrusion deck and its manufacturing method

[0001] The present invention relates to an inorganic composite extrusion-molded deck and a method for manufacturing the same, and more particularly, to an inorganic composite extrusion-molded deck and a method for manufacturing the same, wherein an inorganic composite composition comprising cement, silica powder, iron oxide, a thickener, pulp fiber, a water reducing agent, and water is manufactured by an extrusion method, and during the manufacturing process, after high-temperature and high-pressure curing, surface processing is performed, and then surface treatment is performed with a shot ball to improve strength and suppress slipping, and a cross-section is sealed due to vacuum extrusion to prevent moisture penetration, and a decrease in water absorption rate thereby improves freezing resistance, thereby preventing freezing in the winter, and a non-slip surface to prevent slipping and falling while walking, and to an inorganic composite extrusion-molded deck and a method for manufacturing the same.

[0002] As is well known, we often see structures such as deck walkways and stairs installed in places with beautiful natural scenery and frequent visits, such as hiking trails and lakesides, to allow people to walk more closely and safely in nature.

[0003] Not only in nature but also in ordinary homes, there are increasing cases of constructing terraces or balconies using decks on the front or back of houses to provide a sense of stability to the building and harmony with the garden, while at the same time allowing people to enjoy sunbathing, outdoor dining, and refreshments.

[0004] Previously, these decks were constructed using natural wood, but due to the decrease in natural wood resources and the resulting increase in material costs, and the need for constant maintenance such as oil stain application due to the lack of weather resistance and durability of natural wood when constructed outdoors, they have long since been replaced with synthetic wood.

[0005] Synthetic wood is a material that is made by mixing wood flour and synthetic resin as main raw materials, melting them, adding various additives, and then extruding them to form a board or square material. It is an excellent material that maintains the texture of natural wood to some extent, while also having durability and water resistance superior to natural wood, and does not discolor or warp even after long-term use.

[0006] However, synthetic wood is usually mixed with more than 50% wood powder by weight to maintain strength. Since the wood powder content is high, even though it has superior properties compared to natural wood, there are problems such as being vulnerable to moisture and having poor anti-corrosion and insect repellent effects when considering the standards or conditions required by builders and users for synthetic decks at the present time.

[0007] In addition, as heavy metals and environmental hormones have been detected in synthetic wood, controversy has been raised over its harmfulness to the human body, making the development of eco-friendly materials that can replace synthetic wood urgent.

[0008] Taking these points into consideration, a ceramic deck and its manufacturing method were filed under patent application number 10-2020-0111384.

[0009] In view of the above, the conventional method for manufacturing a general ceramic deck comprises the steps of: mixing a composition composed of cement, silica powder, iron oxide, thickener, pulp, polypropylene fiber, powdered polymer, waterproofing powder resin and water by feeding the mixture mixed in the mixing step into an extrusion molding machine and extrusion molding; cutting the extruded body extruded in the extrusion molding step with hydraulic pressure; loading the cut bodies cut in the hydraulic cutting step onto a pallet for curing; a first curing step of putting the pallet on which the cut bodies are loaded in the loading step into a curing room and curing with steam; a second curing step of putting the first cured body cured with steam in the first curing step into a high-temperature and high-pressure curing room and curing with high-temperature and high-pressure; and, while the second cured body cured in the second curing step passes through a shot ball treatment device, the surface of the second cured body is hit with a shot ball. A method for producing a non-slip product, comprising: a non-slip treatment step for forming a non-slip surface by shorting; a cutting step for cutting the non-slip body whose surface has been made non-slip by the non-slip treatment step into a product specification using a diamond saw; and a water-repellent treatment step for applying an oil-based paint to prevent moisture from penetrating into the standard product cut by the cutting step, wherein, after the first curing step, a de-slabbing step for loading the first cured body onto a high-temperature and high-pressure pallet in order to cure the first cured body in a second curing step is further included; and in the mixing step, the mixture comprises: 45 to 49 parts by weight of cement, 42 to 46 parts by weight of silica powder, 0.1 to 15.8 parts by weight of iron oxide, 0.5 to 0.9 parts by weight of a thickener, 7 to 11 parts by weight of pulp, 0.1 to 15.8 parts by weight of an artificial fiber, and a powder polymer. It is characterized by being composed of 2 to 5 parts by weight of a waterproofing agent powder resin, 2 to 6 parts by weight of a waterproofing agent powder resin, and 22 to 26 parts by weight of water.

[0010] However, a ceramic deck manufactured by a conventional method of manufacturing a general ceramic deck configured in this manner has a disadvantage in that, when the cut body is cured with steam in the first curing step, the moisture inside the cut body is rapidly discharged due to the rapid curing reaction, causing the surface layer of the cut body to become brittle, and when the brittle surface is shot with a shot ball in the non-slip treatment step, the strength of the surface layer is bound to decrease.

[0011] Patent Document 1: Republic of Korea Patent Publication No. 10-2020-0111384 (Title: Ceramic deck and manufacturing method thereof, Publication date: February 17, 2021)

[0013] The above and other additional purposes will be apparent to those skilled in the art without departing from the technical spirit of the present invention by the appended claims.

[0014] In order to achieve the above-described object, the present invention provides a method for manufacturing an inorganic composite extrusion-molded deck, comprising: a mixing step (S110) for mixing a composition comprising cement, silica powder, iron oxide, a thickener, pulp fiber, a water reducing agent, and water by introducing the mixture into a mixer; an extrusion-molding step (S120) for supplying the mixture mixed by the mixing step (S110) to an extrusion-molding machine and extrusion-molding it; a hydraulic cutting step (S130) for cutting the extruded body extruded by the extrusion-molding step (S120) with hydraulic pressure; a loading step (S140) for loading the cut bodies cut by the hydraulic cutting step (S130) onto a pallet for curing; a first curing step (S150) for introducing the pallet loaded with the cut bodies by the loading step (S140) into a curing room and curing it with steam; and a second curing step (S150) for curing the pallet by the first curing step (S150).

[0027] As illustrated, the inorganic composite extrusion molding deck and the manufacturing method thereof according to the present invention are configured to prevent a decrease in the strength of the secondary cured body that may occur due to a surface shot by configuring the secondary cured body to be shot by a shot ball after surface processing of the surface of the secondary cured body produced by the secondary curing step.

[0028] That is, the method for manufacturing the inorganic composite extrusion-molded deck according to the present invention described above comprises a mixing step (S110) for mixing a composition comprising cement, silica powder, iron oxide, thickener, pulp fiber, water reducing agent and water by introducing the mixture into a mixer, an extrusion-molding step (S120) for supplying the mixture mixed by the mixing step (S110) to an extrusion-molding machine and extrusion-molding it, a hydraulic cutting step (S130) for cutting the extruded body extruded by the extrusion-molding step (S120) with hydraulic pressure, a loading step (S140) for loading the cut bodies cut by the hydraulic cutting step (S130) onto a pallet for curing, a first curing step (S150) for introducing the pallet on which the cut bodies loaded by the loading step (S140) are placed into a curing room and cured with steam, and a second curing step (S150) for curing the extruded body cured by the first curing step (S150).

[0029]

[0030] Hereinafter, the manufacturing method of the inorganic composite extrusion molding deck according to the present invention will be described in more detail with reference to the attached drawing 1.

[0031] First, in the method for manufacturing an inorganic composite extrusion deck according to the present invention, the mixing step (S110) is a step for mixing a composition composed of 42 to 49 parts by weight of cement, 40 to 48 parts by weight of silica powder, 0.1 to 15.8 parts by weight of iron oxide, 0.4 to 0.9 parts by weight of thickener, 1.5 to 11 parts by weight of pulp, 0.3 to 0.7 parts by weight of water reducing agent, and 20 to 25 parts by weight of water through a mixer.

[0032] Here, the above-mentioned mixer is configured to circulate cooling water of 3℃ to 5℃ on the outer surface to prevent loss of function of the thickener (loss of function when the temperature is above 40℃) due to temperature increase when mixing the composition.

[0033] And the above-mentioned cement is a typical Portland cement, and since the higher the Blaine value (the finer the powder), the faster the initial strength is developed and the higher the strength increase rate, the cement with a Blaine value of 2800 / g or more is applied in the present invention.

[0034] In addition, the above-mentioned silica powder having a SiO2 content of 90% or more is mixed into cement.

[0035] Silica powder is mixed together to produce a mixture, and the mixture is extruded to produce a deck. In addition, various surface textures can be obtained through the particle-shaped silica powder, and the internal structure can be densified through the silica powder, thereby improving durability.

[0036] Meanwhile, if the above-mentioned silica powder is mixed in an amount less than 42 parts by weight, the strength of the deck produced becomes low, and if the silica powder is more than 46 parts by weight, the mixing ratio with other components other than the silica powder component is not correct, resulting in a problem in that the desired level of strength cannot be obtained.

[0037] In the present invention, when 47 parts by weight of cement and 44 parts by weight of silica powder are mixed, the strength of the produced deck can be realized to a desired degree.

[0038] The above iron oxide can be applied as an inorganic material mined from a blast furnace, etc. in the process of manufacturing steel.

[0039] At this time, iron oxide includes black powder ferrous oxide, red powder ferric oxide, and black powder triferrous oxide, and in oxidizing chlorine, it appears brown to reddish brown, and in anhydrous chlorine, it appears blue-green, gray-blue, dark gray, etc.

[0040] In addition, when clay with a high iron content is fired, it takes on a brick red color, and when iron oxide is added to a boric acid glaze containing alkali, it takes on a dark red color. The synthetic pigment iron oxide is a glaze that mixes iron oxide with cobalt oxide, manganese compounds, copper compounds, etc., and takes on a black color. Depending on the composition of the glaze or the heating temperature, it takes on various colors.

[0041] In addition, when colored iron oxide and synthetic pigment iron oxide are used as coloring materials for extrusion molding decks, they must have good dispersibility and fine particles to have excellent coloring power. In order to meet the above-mentioned performance requirements, the present invention uses particles having a particle size of 325 to 1200 mesh.

[0042] The above-mentioned thickener performs the function of improving the physical properties of the deck.

[0043] Such thickeners preferably have a viscosity of 35,000 to 75,000.

[0044] The above-mentioned pulp fiber is a natural fiber that has little change in length due to temperature deviation and is excellent in water resistance, fire resistance, and sound insulation, and is thus also applied to the present invention.

[0045] In addition, the above-mentioned water reducing agent is configured to improve workability while reducing the amount of water. If it is added in an amount of 0.3 parts by weight or less, the amount of water increases, and if it is added in an amount of 1.0 parts by weight or more, the amount of water is reduced too much, making mixing difficult. Therefore, it is preferable to add the above-mentioned water reducing agent in an amount of 0.3 to 1.0 parts by weight.

[0046] The above-described extrusion molding step (S120) is a step for making an extruded body by using an extrusion molding machine in which internal air is discharged by a vacuum device from the mixture produced by the above-described mixing step (S110).

[0047] Here, the extrusion molding machine described above is configured to have cooling water of 3°C to 5°C circulated on the outer surface to prevent tearing of the extrusion molding and clogging of the extrusion molding machine due to loss of function of the thickener as the internal temperature increases when the composition is extruded into an extrusion molding body, and at the same time, the internal pressure of the extrusion molding machine is configured to be maintained at 0.08 to 0.1 MPa to prevent bubbles and air layers from forming inside when manufacturing an extrusion molding body, thereby increasing strength.

[0048] In addition, the extruded body formed by the extrusion molding step (S120) described above is formed into a square plate shape having a predetermined thickness, and a plurality of holes having a circular or square cross-section are formed in the longitudinal direction in the central portion to reinforce strength and reduce weight.

[0049] In addition, on one side and the other side of the above deck, a joining projection and a joining groove are further formed in the longitudinal direction so that the deck can be joined to another adjacent deck.

[0050] The above-mentioned hydraulic cutting step (S130) is a step of cutting the extruded body extruded by the extrusion molding step (S120) using hydraulic pressure.

[0051] Here, the above extruded body is cut with hydraulic pressure so as to obtain a clean cut surface while preventing deformation when cutting the extruded body in a non-cured state.

[0052] The above-described loading step (S140) is a step of loading the deck cutting body cut by the above-described hydraulic cutting step (S130) onto a pallet to cure it through the above-described first curing step.

[0053] The above-mentioned first curing step (S150) is a step in which the pallet on which the cutting body is loaded by the above-mentioned loading step (S140) is placed in a curing room and cured with steam.

[0054] At this time, the above-mentioned cut body is cured in a curing room at a temperature of 60℃ to 75℃ for 10 to 18 hours to prevent cracking.

[0055] The above-mentioned de-plate step (S160) is a step for loading the first cured body, which has been cured for the first time, onto a high-temperature, high-pressure pallet in order to cure it in the second curing step (S170) after the first curing step (S150).

[0056] The above-mentioned second curing step (S170) is a step in which the first cured body, which has been removed from the high-temperature and high-pressure pallet in the above-mentioned removal step (S160), is placed in a high-temperature and high-pressure curing room and cured at high temperature and high pressure to create a second cured body.

[0057] At this time, the above-mentioned secondary curing body is cured at a temperature of 140℃ to 180℃ and a pressure of 7kg / cm so that the primary curing body cured by the above-mentioned primary curing step becomes ceramic. 2 ~ 10kg / cm 2 Secondary curing is performed in a high temperature and high pressure curing room for 10 to 18 hours under a pressure environment.

[0058] The above cutting step (S180) is a step of cutting the secondary cured body cured into ceramic by the secondary curing step (S170) using a diamond saw to meet the product specifications.

[0059] The above-mentioned surface processing step (S190) is a step for processing, i.e., cutting, the surface of the standard product cut by the above-mentioned cutting step (S180) using a surface processing machine.

[0060] Here, in the surface processing step (S190) described above, the surface processing of the standard product is configured to process the rough surface of the primary cured body cured by the primary curing step (S150), and then, in the non-slip processing step (S200), non-slip processing is performed to prevent a decrease in strength of the surface layer of the inorganic composite extrusion deck by using a surface processing machine to process the surface to a thickness of 0.3 to 1.0 mm.

[0061] That is, in the surface processing step (S190) described above, the surface of the second cured body that has been cured up to the second curing step (S170) is cured in a crumbly manner as shown in Fig. 3 as the moisture inside the cut body is rapidly removed by the first curing step (S150). If this cured body is shot with a shot ball through the non-slip treatment step (S200), the surface hardness is bound to decrease.

[0062] Accordingly, by surface-processing the surface of the secondary cured body cured up to the second curing step (S170) through the surface processing step (S190) as shown in Fig. 4 to remove the rough surface, and then short-cutting it with a short ball through the non-slip processing step (S200), the surface hardness does not decrease.

[0063] Meanwhile, if the surface processing of the standard product is performed to a thickness of 0.3 mm or less in the surface processing step (S190) described above, the rough surface of the primary cured body cured in the primary curing step (S150) cannot be processed completely, and if the surface processing is performed to a thickness of 1.0 mm or more, the surface may be processed too much, which may lower the strength of the inorganic composite extrusion deck. Therefore, in the surface processing step (S190), it is preferable to process the surface of the standard product to a thickness of 0.3 to 1.0 mm using a surface processing machine as described above.

[0064] The above-mentioned non-slip treatment step (S200) is a non-slip treatment step for forming a non-slip surface by short-balling the surface of the surface-processed object, which has been surface-processed by the surface processing step (S190), while passing through a shot-ball treatment device.

[0065] At this time, the speed at which the surface-processed material passes through the short ball treatment machine is 15 m to 25 m / min, and the short ball is configured to have a size of 0.4 mm to 0.8 mm.

[0066] Meanwhile, if the speed at which the surface-processed object passes through the shot ball treatment device is 25 m / min or more and the short ball is 0.4 mm or less in size, the surface of the surface-processed object surface-processed by the surface treatment step (S190) is not treated for non-slip, and if the speed is 15 m / min or less and the short ball is 0.8 mm or more in size, the short ball treatment on the upper surface of the surface-processed object is performed too much and the groove portion disappears, so it is preferable to perform the short ball treatment at the speed and size described above.

[0067] The above-described width processing step (S210) is a step for processing the product width into a standard while a diamond wheel rotates on both sides of the non-slip body having a non-slip surface formed by the above-described non-slip processing step (S200) while passing through a width processing machine conveyor, and the above-described water-repellent processing step (S220) is a step for applying an oil-based paint to the width-processed standard product processed into a width by the above-described width processing step (S210) to prevent moisture from penetrating.

[0068] As described above, the inorganic composite extrusion molding deck (300) manufactured by the method for manufacturing the inorganic composite extrusion molding deck according to the present invention is formed in the shape of a square plate having a predetermined thickness as shown in FIG. 2, and a plurality of holes having a circular or square cross-section are formed in the longitudinal direction in the central portion for strength reinforcement and sound insulation.

[0069] In addition, one side and the other side of the above-mentioned inorganic composite extrusion deck (300) are provided with a coupling protrusion and a coupling groove formed in the longitudinal direction so that the deck can be coupled with another adjacent deck.

[0070] In addition, the surface of the above-described inorganic composite extrusion deck (300) is manufactured by a non-slip treatment step after the surface processing step as shown in FIG. 2, and thus is formed as a rough surface to prevent strength loss and slipping.

[0071] The above description is merely an illustrative description of the technical idea of ​​the present invention, and those skilled in the art will appreciate that various modifications and variations may be made without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the technical idea of ​​the present invention, and the scope of the technical idea of ​​the present invention is not limited by these embodiments. The scope of protection of the present invention should be interpreted by the following claims, and all technical ideas within a scope equivalent thereto should be interpreted as being included in the scope of the rights of the present invention.
