건축용 내장마감재 제조방법 및 이를 이용한 요철무늬가 형성된 건축용 내장마감재{Method of manufacturing interior board and Interior board having unevenness pattern using the same}Method for manufacturing interior finishing material for construction and interior finishing material for construction with irregular patterns using the same {Method of manufacturing interior board and Interior board having unevenness pattern using the same}

본 발명은 건축용 내장마감재 제조방법에 관한 것으로서, 더욱 상세하게는 펄라이트와 같은 다공성 소재를 이용하여 건축용 내장마감재를 제작하되, 내장마감재의 표면에 자연스러운 요철무늬가 형성되도록 하는 건축용 내장마감재의 제조방법 및 이를 이용하여 제작된 요철무늬가 형성된 건축용 내장마감재에 관한 것이다.The present invention relates to a method for manufacturing an interior finishing material for construction, and more specifically, to manufacture an interior finishing material for construction using a porous material such as pearlite, a method for manufacturing an interior finishing material for construction so that a natural uneven pattern is formed on the surface of the interior finishing material, and It is related to the interior finishing material for constructions having uneven patterns produced using them.

일반적으로 건축용 내장마감재(단열패널 또는 단열재)는 각종 건축물의 단열, 방음 및 완충재로 쓰이는 경량 건축재이다. 생활수준의 향상과 산업의 고도화 및 정보화 사회의 급변하는 환경에 대응하는 건축물의 대형화, 첨단화, 기능화가 요구되는 현실에서 아파트, 복합상가 등의 고층화, 대형화는 필연적인 현상이다. 이에 건축자재의 경량, 불연, 방음, 단열 기능을 동시에 충족시켜주는 소재를 개발하기 위한 연구, 노력은 지속되어 왔으며, 이러한 요구에 부응하여 다공질의 건축자재가 여러 분야에서 개발되고 있는 실정이다.In general, interior finishing materials for construction (insulating panels or insulation) are lightweight construction materials used as insulation, sound insulation and cushioning materials for various buildings. It is inevitable that high-rise, large-scale apartments, multi-storey buildings, etc., are necessary in order to increase the standard of living, industrialization, and informatization. Accordingly, research and efforts to develop materials that simultaneously meet the lightweight, non-combustible, soundproofing, and insulating functions of building materials have continued, and in response to these demands, porous building materials have been developed in various fields.

지금까지 개발된 건축자재들은 스티로폼, 우레탄, 석면 또는 석고보드 등으로 제작되고 있으나, 경량성, 불연성, 방음성, 단열보온성 등을 모두를 충족시키지 못하고 있다. 예를 들어, 스티로폼 및 우레탄으로 제작된 우레탄 폼은 내부의 공기로 인해 외부의 찬공기는 방어하고 내부의 열기는 외부로 차단하는 보온성이 뛰어나며 반면, 비교적 열에 약한 문제점이 있어 화재시 유독성 가스 분출로 인명피해가 매우 높으며, 우레탄 폼 역시 스티로폼에 비해선 점화속도가 낮으나 발화 후에는 검은 연기와 가스가 배출되며 중량이 무거운 문제점이 있다. 그리고 석면은 내화성이 강하고 마찰에 잘 견딜 수 있으며 화학약품에 대한 저항성, 전기에 대한 절연성이 우수하나 석면에서 발생하는 먼지는 사람에게 암과 같은 질병을 유발시킬 뿐만 아니라 물에 젖으면 무게가 무거워져 작업성이 떨어지는 문제점이 있다. Building materials developed so far are made of styrofoam, urethane, asbestos, or gypsum board, but they do not satisfy all of light weight, non-combustibility, sound insulation, and heat insulation. For example, urethane foam made of styrofoam and urethane has excellent heat retention that protects the outside air from air and blocks the heat inside from the outside due to the air inside. The lifespan is very high, and urethane foam also has a lower ignition rate than Styrofoam, but after ignition, black smoke and gas are discharged and there is a heavy weight problem. In addition, asbestos is fire-resistant, resistant to friction, has excellent chemical resistance and electrical insulation, but dust generated by asbestos causes diseases such as cancer to humans, and when wet, it becomes heavy. There is a problem of poor workability.

이러한 문제점을 해결하기 위해서, 최근에는 펄라이트를 주재료로 한 건축용 내장마감재가 개발되고 있다. 특히, 팽창된 펄라이트(Perlite: 팽창된 진주암)은 화산의 활동시 급랭 된 펄라이트 계통의 원석을 분쇄하여 800℃ 이상의 고온으로 급열을 가하여 팽창시킨 것이다. 이러한 팽창된 펄라이트는 무수히 많은 공극의 효과로 단열, 보온, 흡음 기능이 우수하다. 본 발명은 이러한 특성이 있는 팽창 펄라이트를 주재료로 한 건축용 내장마감재의 제조방법에 관한 것이다. In order to solve this problem, recently, interior finishing materials for construction using pearlite as a main material have been developed. In particular, the expanded perlite (Perlite: expanded perlite) is a pulverized ore pulverized ore pulverized during volcanic activity, which is expanded by applying rapid heat at a high temperature of 800 ° C or higher. This expanded pearlite has excellent insulation, heat retention, and sound absorption functions due to the effect of countless pores. The present invention relates to a method for manufacturing a building interior finishing material using expanded pearlite having such characteristics as a main material.

종래 기술에 따른 불연성 경량 건축재의 제조방법은, 4~5mm의 입경 크기를 갖는 팽창된 펄라이트 70중량부와 바인더로서 규산소다 용액 5중량부, 아나타제형 이산화티탄 15중량부, 325 메시 크기의 알로펜 10중량부를 믹서기에 넣고 1시간 교반한 다음, 기초 성형틀에 투입하여 정해진 형태로 성형하고, 성형 완료된 성형체를 내부 온도가 200~ 500℃로 고정된 가압식 열풍성형기에서 300㎏/㎠의 압력을 가하며 20분간 소성하며, 소성 완료된 성형체를 냉각기에서 냉각하여 성형체를 제조하는 것이다.A method of manufacturing a non-combustible lightweight building material according to the prior art is 70 parts by weight of expanded pearlite having a particle size of 4 to 5 mm and 5 parts by weight of a sodium silicate solution as a binder, 15 parts by weight of anatase-type titanium dioxide, and aloe pen of 325 mesh size Put 10 parts by weight in a blender, stir for 1 hour, put it in a basic molding mold, mold it into a predetermined shape, and apply a pressure of 300 kg / cm2 in a pressurized hot-air molding machine with an internal temperature of 200 to 500 ° C. It is fired for 20 minutes, and the molded body is manufactured by cooling the completed molded body in a cooler.

즉, 도 4에서 보는 바와 같이, 종래 기술에 따른 건축용 내장마감재 제조방법의 일 예는, 팽창 펄라이트를 포함하는 혼합물을 기초 성형틀(40)에 투입하여 정해진 형태로 가압성형하고, 성형 완료된 성형체를 내부 온도가 200~500℃로 고정된 가압식 열풍성형기(46)에서 300㎏/㎠의 압력을 가하며 20분간 소성하여 성형체를 성형한 다음, 소성 완료된 성형체를 냉각기(50)에서 냉각한 후 가공기(55)로 표면을 가공한 다음 절단기(60)를 통해 원하는 규격으로 절단하여 제품(10)을 완성하게 된다.That is, as shown in Figure 4, an example of a method for manufacturing a building interior finishing material according to the prior art, by injecting a mixture containing expanded pearlite into the foundation molding frame 40, press-molding in a predetermined form, and the molded molded body After pressurizing 300 kg / cm 2 in a pressurized hot air forming machine 46 having an internal temperature of 200 to 500 ° C. and firing for 20 minutes to mold the molded body, the molded body is cooled in a cooler 50 and then processed (55). ), And then cut to the desired size through the cutter 60 to complete the product 10.

또한, 종래 기술에 따른 펄라이트가 함유된 단열재의 제조방법의 다른 실시 예는, 팽창 펄라이트를 분쇄하여 준비하는 단계(S20); 팽창 펄라이트에 유무기 복합바인더를 분무하여 코팅하는 단계(S21); 코팅된 팽창 펄라이트를 열풍으로 건조하는 단계(S22); 건조된 팽창 펄라이트를 고온에서 성형하는 단계(S23); 완성품의 형태와 크기로 가공하는 단계(S24);를 포함하여 이루어진다. In addition, another embodiment of a method of manufacturing a heat-insulating material containing pearlite according to the prior art includes: preparing an expanded pearlite by grinding (S20); Spraying and coating the expanded pearlite with an organic-inorganic composite binder (S21); Drying the coated expanded pearlite with hot air (S22); Forming the dried expanded pearlite at a high temperature (S23); It comprises a; step (S24) for processing in the form and size of the finished product.

이와 같이, 종래 기술의 건축용 내장마감재 제조방법을 이용하여 제작된 내장마감재는, 고온 및 고압하에서 성형체를 압출 성형한 다음 가공기로 표면을 가공한 후 절단기로 절단하는 방식으로 제조하기 때문에 도 5에서 보는 바와 같이, 완성된 건축용 내장마감재의 표면이 매끄럽고 테두리는 직선형으로 이루어진다. As described above, since the interior finishing material manufactured using the prior art construction interior finishing material manufacturing method is manufactured by extruding a molded body under high temperature and high pressure, and then processing the surface with a processing machine and then cutting it with a cutting machine. As described, the surface of the finished interior finishing material for construction is smooth and the rim is made straight.

따라서 종래 기술에 따른 건축용 내장마감재 제조방법은, 내장마감재의 표면에 자연스러운 요철무늬를 표현하기 어려울 뿐만 아니라 고온 및 고압하에서 성형하기 때문에 제조공정이 복잡하고 고가의 장비를 사용하기 때문에 내장마감재의 가격이 비싸고 다품종 소량생단에 적합하지 않다는 단점이 있었다. Therefore, the method for manufacturing interior finishing materials according to the prior art is difficult to express a natural uneven pattern on the surface of the interior finishing materials, and is also molded under high temperature and high pressure, so the manufacturing process is complicated and expensive equipment is used. The disadvantage was that it was expensive and was not suitable for small batches of multi-species.

도 1은 본 발명에 따른 요철무늬가 형성된 건축용 내장마감재(1)의 일 예를 보여주는 것이다. 도시된 바와 같이, 요철무늬가 형성된 건축용 내장마감재(1)는 일정한 두께를 갖는 사각 형상의 본체(11)로 이루어지고, 상기 본체(11)의 표면에는 다수의 요철무늬(12)가 형성된다. 또한, 본체(11)의 가장자리는 귀따기 가공한 형태로 불규칙한 모양(13)을 이루고 있다.Figure 1 shows an example of the interior finishing material (1) for the uneven pattern formed in accordance with the present invention. As shown in the drawing, the interior finishing material 1 for a construction in which an uneven pattern is formed is formed of a rectangular body 11 having a constant thickness, and a plurality of uneven patterns 12 are formed on the surface of the body 11. In addition, the edge of the main body 11 has an irregular shape 13 in the form of chamfering.

Subsequently, FIG. 2 is a schematic flowchart showing a process for manufacturing the interior finishing material 1 for construction according to the present invention, and FIG. 3 is a flowchart showing a process for manufacturing the interior finishing material 1 for construction according to the present invention.

도시된 바와 같이, 본 발명의 건축용 내장마감재 제조공정은 크게 요철무늬가 형성된 주형보드(20)를 제작하는 공정(A)과, 요철무늬가 형성된 내장마감재(1)를 제작하는 공정(B)으로 이루어진다. 즉, 요철무늬가 형성된 주형보드(20)를 제작하는 공정(A)은, 요철무늬가 형성된 원형보드(10)로부터 그 요철무늬를 그대로 복제한 주형보드(20)를 제작하는 과정이다. 이때 원형보드(10)는 자연의 석재나 목재로부터 얻거나 인위적으로 요철무늬를 디자인한 판재로 이루어질 수 있다. 그리로 상기 요철무늬가 형성된 내장마감재(1)를 제작하는 단계(B)는 상기한 주형보드(20)로부터 다수의 내장마감재(1)를 성형하는 과정이다. As shown, the manufacturing process of the interior finishing material for construction of the present invention is largely the process (A) of manufacturing the molded board 20 having an uneven pattern and the process of manufacturing the interior finishing material 1 with an uneven pattern (B). Is done. That is, the process (A) of manufacturing the mold board 20 on which the uneven pattern is formed is a process of manufacturing the mold board 20 replicating the uneven pattern as it is from the circular board 10 on which the uneven pattern is formed. At this time, the circular board 10 may be obtained from natural stone or wood, or may be made of a plate material artificially designed with an uneven pattern. Thus, the step (B) of manufacturing the interior finishing material 1 on which the uneven pattern is formed is a process of molding a plurality of interior finishing materials 1 from the mold board 20 described above.

먼저, 요철무늬가 형성된 주형보드(20)를 제작하는 공정은, 자연의 석재나 목재의 일부로부터 원형보드(10)를 얻거나 인공적으로 요철무늬를 디자인하여 원형보드(10)를 제작하는 원형보드 준비단계(S10)와; 요철무늬가 형성된 원형보드(10)를 일정한 형상의 몰드 틀(21)에 장착하고(S20), 액상 PPS(폴리페닐렌 설파이드)와 석분의 혼합물을 붓고(S30), 서서히 굳힌 다음(S40) 탈형하여(S50) 표면에 요철무늬가 형성된 주형보드(20)를 제작한다. First, the process of manufacturing the molded board 20 on which the uneven pattern is formed is obtained by obtaining the circular board 10 from a part of natural stone or wood or artificially designing the uneven pattern to manufacture the circular board 10 Preparation step (S10) and; The circular board 10 on which the uneven pattern is formed is mounted on a mold frame 21 of a predetermined shape (S20), a mixture of liquid PPS (polyphenylene sulfide) and stone powder is poured (S30), and gradually hardened (S40) and demolded (S50) to produce a mold board 20 having an uneven pattern formed on the surface.

이때, 주형보드(20)는 PPS(폴리페닐렌 설파이드;Poly Phenylene Sulfide)와 석분의 혼합물로 이루어진다. 폴리페닐렌 설파이드(PPS)는 엔지니어링 플라스틱으로서, 강도, 내열성, 내약품성 등이 우수하고, 열가소성 수지이므로 성형이 용이하다. 그리고 석분은 천연석 광물을 분쇄하여 고운 분말 형태로 가공한 것으로 300 메쉬망을 통과하는 고운 가루만을 사용한다. 바람직하게 석분은 차돌가루로 이루어진다.At this time, the mold board 20 is made of a mixture of PPS (Poly Phenylene Sulfide) and stone powder. Polyphenylene sulfide (PPS) is an engineering plastic, and has excellent strength, heat resistance, and chemical resistance, and is easily molded because it is a thermoplastic resin. In addition, the stone powder is a fine powder processed by crushing natural stone minerals, and uses only fine powder that passes through a 300 mesh network. Preferably, the stone powder is made of tea powder.

또한, PPS는 주형보드(20)의 액체 상태의 것을 사용한다. 즉, 액상의 PPS에 일정량의 석분을 혼합하여 사용한다. 바람직하게, 상기 PPS와 석분의 혼합비는 PPS 60~70중량부에 석분 30~40중량부를 혼합한다. 즉, 석분이 30중량부 이하이면, 주형보드(20)의 강도가 떨어지고, 석분이 40중량부 이상이면 표면이 거칠고 딱딱하여 탈형이 어렵게 된다. In addition, the PPS uses the liquid form of the mold board 20. That is, a certain amount of stone powder is mixed with liquid PPS to be used. Preferably, the mixing ratio of the PPS and the stone powder is 30 to 40 parts by weight of the stone powder 60 to 70 parts by weight of PPS. That is, if the powder is 30 parts by weight or less, the strength of the mold board 20 is lowered, and if the powder is 40 parts by weight or more, the surface is rough and hard, so that the demoulding is difficult.

이어, 요철무늬가 형성된 내장마감재(1)를 제작하는 공정은, 상기한 A 단계를 통해 제작된 주형보드(20)를 이용하여 다수의 내장마감재(1)를 차례로 제작하는 공정으로서, 구체적으로, 상기 주형보드(20)를 일정한 형상의 몰드 틀(31)에 장착하고(S60), 팽창 펄라이트와 무기 바인더 및 강화조제를 일정 비율로 혼합한 혼합물(32)을 주형보드(20) 위에 채운 다음(S70), 상부 몰드(33)를 이용하여 일정한 압력으로 가압하여 내장마감재(1)를 성형하는 내장마감재 성형단계(S80)와 상기 몰드 틀로부터 성형된 내장마감재(1)를 분리하는 취출단계(S90)와, 취출된 내장마감재(1)를 일정한 온도로 건조하는 건조단계(S100);를 포함한다.Subsequently, the process of manufacturing the interior finishing material 1 having an uneven pattern is a process of sequentially manufacturing a plurality of interior finishing materials 1 using the mold board 20 produced through the above-described step A, specifically, The mold board 20 is mounted on a mold frame 31 of a predetermined shape (S60), and then a mixture 32 of a mixture of expanded pearlite, an inorganic binder, and a reinforcing aid is filled in the mold board 20, and then ( S70), an interior finishing material forming step (S80) of molding the interior finishing material 1 by pressing at a constant pressure using the upper mold 33 and a taking-out step of separating the interior finishing material 1 molded from the mold mold (S90) And a drying step (S100) of drying the taken-out interior finishing material 1 at a constant temperature.

이때, 상기 주형보드(20)는 PPS를 주재료로 이루어지고 그 표면에는 요철무늬가 구비된다. 그리고 내장마감재(1)는 팽창된 펄라이트를 주재료로 이루어진다. 팽창된 펄라이트(Perlite: 팽창된 진주암)은 화산의 활동시 급랭 된 펄라이트 계통의 원석을 분쇄하여 800℃ 이상의 고온으로 급열을 가하여 당초 부피의 20배 이상으로 팽창시킨 것이다. At this time, the mold board 20 is made of PPS as a main material, and the surface is provided with an uneven pattern. And the interior finishing material 1 is made of expanded pearlite as a main material. The expanded perlite (perlite: expanded perlite) is a pulverized ore crushed gemstone during volcanic activity, rapidly heated at a temperature of 800 ° C or higher, and expanded to more than 20 times the original volume.

이러한 팽창된 펄라이트는 무수한 작은 공간이 생기게 되면서 그 무게가 매우 경량화되고 무수히 많은 공극으로 단열, 보온, 보냉 및 흡음 기능이 우수하게 된다. 바람직하게 팽창된 펄라이트는 50~300메쉬망을 통과하는 분말을 사용한다. 즉, 50메쉬 이상의 펄라이트 입자로 만들어진 내장마감재(1)는 강도가 약하고 표면이 거칠다. 반면에 300메쉬 이하의 펄라이트 입자로 만들어진 내장마감재(1)는 공극이 적어서 무겁고 단열 및 흡음 성능이 떨어진다.As the expanded pearlite has a myriad of small spaces, its weight is very light, and its numerous pores provide excellent insulation, heat retention, cold insulation, and sound absorption. Preferably, the expanded pearlite is a powder that passes through a 50-300 mesh network. That is, the interior finishing material 1 made of pearlite particles of 50 mesh or more has a weak strength and a rough surface. On the other hand, the interior finishing material 1 made of pearlite particles of 300 mesh or less has a small amount of voids, and is heavy, and has poor insulation and sound absorption performance.

또한, 상기 내장마감재(1)는 팽창된 펄라이트 외에 황토, 운모, 규조토, 질석 등에서 선택된 하나 또는 둘 이상의 성분을 혼합한 혼합물로 이루어질 수 있다. 예를 들어, 황토나 규조토 등은 내장마감재(1)를 특정 색으로 착색하거나 항균기능을 갖게 한다. 이때, 황토, 운모, 규조토, 질석 등의 광물은 5~10중량부로 혼합될 수 있다. In addition, the interior finishing material 1 may be made of a mixture of one or more components selected from ocher, mica, diatomaceous earth, vermiculite, etc., in addition to expanded pearlite. For example, yellow soil or diatomaceous earth makes the interior finishing material 1 colored in a specific color or has an antibacterial function. At this time, minerals such as ocher, mica, diatomaceous earth, vermiculite may be mixed in 5 to 10 parts by weight.

그리고 상기 내장마감재(1)는 팽창된 펄라이트를 포함하는 석분 혼합물과 무기질 바인더 및 강화조제의 혼합물로 이루어진다. 바람직하게 팽창된 펄라이트를 포함하는 석분 혼합물과 무기질 바인더 및 강화조제의 혼합비는 팽창된 펄라이트를 포함하는 석분 혼합물 40~65중량부, 무기질 바인더 30~40중량부 및 강화조제 5~30중량부의 비율로 혼합될 수 있다. And the interior finishing material (1) is composed of a mixture of a stone powder containing an expanded pearlite, an inorganic binder and a reinforcing aid. Preferably, the mixing ratio of the stone powder mixture containing expanded pearlite and the inorganic binder and the reinforcing aid is in the proportion of 40 to 65 parts by weight of the stone powder mixture containing the expanded pearlite, 30 to 40 parts by weight of the inorganic binder and 5 to 30 parts by weight of the reinforcing aid. Can be mixed.

따라서 팽창된 펄라이트를 포함하는 석분 분말에 경화조제 분말을 균일하게 혼합한 후 무기질 바인더를 일정량 첨가하여 혼합한다. 이때, 상기 무기질 바인더는, 액상으로서, 규산나트륨(Sodium silicate) 33.5중량부와 물(Water) 66.5중량부의 혼합물로 이루어진다. 또한, 강화조제는, 규산알루미늄(Aluminum silicate) 분말로 이루어진다. 즉, 강화조제는 팽창된 펄라이트 입자 사이에 개재되어 내장마감재(1)의 강도를 높이고 무기질 바인더는 팽창된 펄라이트 입자들을 접착시키는 역할을 한다. Therefore, after mixing the curing aid powder uniformly with the powder of the powder containing the expanded pearlite, a certain amount of an inorganic binder is added and mixed. At this time, the inorganic binder, as a liquid, is made of a mixture of sodium silicate (Sodium silicate) 33.5 parts by weight of water (Water) 66.5 parts by weight. In addition, the reinforcing aid is made of aluminum silicate powder. That is, the reinforcing aid is interposed between the expanded pearlite particles to increase the strength of the interior finishing material 1 and the inorganic binder serves to bond the expanded pearlite particles.

그리고 팽창 펄라이트를 포함하는 석분 혼합물과 무기 바인더 및 강화조제를 일정 비율로 혼합한 혼합물(32)을 주형보드(20) 위에 채운 다음 프레스로 상부 몰드(33)를 가압하여 표면에 요철무늬가 형성된 내장마감재(1)를 성형한다. 이때, 내장마감재(1)의 성형은 상온에서 이루어지고 상부 몰드(33)를 가압하는 프레스의 용량은 10~15t이 바람직하다.Then, the mixture of the powder mixture containing the expanded pearlite, the inorganic binder, and the reinforcing aid is mixed in a certain ratio, and then the mixture 32 is filled on the mold board 20, and then the upper mold 33 is pressed with a press to form an uneven pattern on the surface. The finishing material (1) is molded. At this time, the molding of the interior finishing material 1 is performed at room temperature, and the capacity of the press for pressing the upper mold 33 is preferably 10 to 15 tons.

이어, 성형이 완료된 내장마감재(1)는 몰드 틀(31)로부터 성형된 분리한다. 이때, PPS(폴리페닐렌 설파이드)를 주원료로 하는 주형보드(20)는 표면이 매끄럽고 유연한 특성이 있어 별도로 이형제를 사용하지 않더라도 내장마감재(1)를 쉽게 분리할 수 있다. 그리고 몰드 틀(31)로부터 분리된 내장마감재(1)는 80~90℃의 건조로에서 건조하여 수분을 제거한다. Subsequently, the interior finishing material 1 having been molded is separated from the mold mold 31. At this time, the mold board 20 using PPS (polyphenylene sulfide) as a main raw material has a smooth and flexible surface, so that the interior finishing material 1 can be easily separated without using a release agent. And the interior finishing material 1 separated from the mold mold 31 is dried in a drying furnace at 80 to 90 ° C to remove moisture.

이상에서 설명한 바와 같이, 본 발명에 따른 건축용 내장마감재 제조방법은, 종래기술에 따른 압출성형, 고온소성, 절단 및 표면가공 등의 공정을 생략할 수 있어 제조공정을 단순화하고 상온 저압에서 성형할 수 있기 때문에 에너지를 절약할 수 있을 뿐만 아니라 내장마감재의 표면에 자연스러운 요철무늬가 형성되며 다품종 소량생산에 유리한 효과가 있다. As described above, the method for manufacturing the interior finishing material for construction according to the present invention can omit processes such as extrusion molding, high temperature firing, cutting and surface processing according to the prior art, thus simplifying the manufacturing process and molding at room temperature and low pressure. Therefore, not only energy can be saved, but also a natural uneven pattern is formed on the surface of the interior finishing material, and it has an advantageous effect in small quantity production of multiple kinds.

또한, 본 발명은 내구성이 우수하면서도 표면이 매끄럽고 어느 정도의 유연성을 갖는 PPS(폴리페닐렌 설파이드)로 이루어진 주형보드(20)를 사용함으로써 자연스러운 요철무늬의 복제하기 용이하고 이형제를 사용하지 않고도 내장마감재(1)를 탈형할 수 있을 뿐만 아니라 주형보드(20)의 제작 및 내장마감재(1)의 성형이 용이하기 때문에 사용자의 다양한 요구에 따라 다품종 소량 생산이 가능하다는 효과가 있다. In addition, the present invention is excellent in durability, but the surface is smooth and has a certain degree of flexibility by using the mold board 20 made of PPS (polyphenylene sulfide), so that it is easy to replicate natural uneven patterns and the interior finishing material without using a release agent. (1) Not only can the mold be demolded, but also the production of the mold board 20 and the molding of the interior finishing material 1 are easy, and thus there is an effect that small quantities of multiple products can be produced according to various needs of users.
