Description
본 발명은 단섬유와 펄프를 이용한 판재류의 제조방법에 관한 것이다.The present invention relates to a method for producing a sheet material using short fibers and pulp.
좀더 구체화하면, 봉제공장에서 나온 스크랩(scrap)을 3-4mm의 단섬유(화학섬유 또는 면섬유)로 처리하여 종이펄프 또는 폐펄프를 혼합한 다음 특정의 결착제를 가하여 판재를 제조하는 것으로 결착제는 액상 페놀수지로 하여 가온가압 하였을 때 가볍고 경량이며 강도가 높고 면이 고른 판재류의 물성을 갖도록한 단섬유와 펄프를 이용한 판재류의 제조방법에 관한 것이다.More specifically, the scrap from the sewing factory is treated with short fibers (chemical or cotton fibers) of 3-4 mm, mixed with paper pulp or waste pulp, and then added with a specific binder to produce a plate. The present invention relates to a method for producing a sheet material using short fibers and pulp, which is made of liquid phenolic resin, which has light, light weight, high strength, and even surface properties when heated and pressed.
종래에는 수분함량을 8%-10%로 조성한 펄프 잔재에 로진변성 페놀수지 10-50wt% 및 p-톨루엔설폰산 및 인산 또는 염산등 산촉매 3-15wt%를 첨가하여 가압 또는 가열하여 성형가공하는 펄프잔재를 주재로한 합판류의 제조방법이 있으나, 이 방법은 펄프제조공정에서 배출된 폐기물을 처리하여 특정의 로진변성 페놀수지로 화학적 반응을 일으켜 섬유질을 목질화시키고, 유연성을 부여하기 위하여 갈대입상물을 가하며, 여기에 무기질을 첨가시켜 내약품성등 제반물성을 갖도록 수지의 경화결합에 의해 제조하는 방법이다. 따라서, 이 방법은 제조공정에 따라 처리되는 특정의 각종 화학약품 침 처리물질의 수가 많고 제품의 물성에 있어서도 인장강도 및 절곡강도가 우수하지 못하고 또한 제품의 중량도 무거워서 사용에 불편하며 또한 폴리프로필렌과 목분을 혼합시켜 판재를 제조하는 방법도 있었으나, 설비의 규모가 방대하고 처리공정이 복잡하여 현실적으로는 비경제적이었다.Conventionally, 10-50 wt% rosin-modified phenolic resin and 3-15 wt% of acid catalysts such as p-toluenesulfonic acid, phosphoric acid, or hydrochloric acid are added to the pulp residue having a water content of 8% -10%, followed by molding or pressing. There is a manufacturing method of plywood mainly based on residues, but this method treats the waste discharged from the pulp manufacturing process and chemically reacts with a specific rosin-modified phenolic resin to granulate the fiber and give flexibility to give flexibility. It is a method of manufacturing by hardening of resin to add the inorganic material to have various properties such as chemical resistance by adding. Therefore, this method is inconvenient to use because it has a large number of specific chemical acupuncture treatment materials treated according to the manufacturing process, the tensile strength and bending strength are not excellent in the physical properties of the product, and the weight of the product is heavy, and it is also inconvenient to use polypropylene and There was also a method of manufacturing wood by mixing wood powder, but it was uneconomical due to the large scale of the equipment and the complicated processing process.
또한, 하드 보오드(hard board)판재는 처리공정이 복잡하고, 열경화성수지와 목분을 혼합하여 제조되어 역시 성형성이 없으며, 서립가 방대하여 비경제적이었다.In addition, the hard board (hard board) plate is a complex process, manufactured by mixing the thermosetting resin and wood powder, also not formability, the stand was large and uneconomical.
또한 현재 시중에서 판매되고 있는 페이퍼 보오드(paper board)는 국내에서 다수 생산되고 있으나, 그 제품은 물성에 있어서 내수처리가 약하며 사용용도가 제한적이고 생산가격도 고가이어서 비경제적이었다.In addition, a large number of paper boards currently on the market are produced in Korea, but their products are inexpensive due to their weak physical properties, limited use, and high production prices.
따라서 본 발명은 상기에서 설명한 바와 같이 종래 판재에 대한 결점을 해소한 판재류를 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a plate material that solves the defects of the conventional plate material as described above.
본 발명은 단섬유(화학 섬유와 면섬유)를 1 : 1로 혼합시켜 3-4mm의 길이로 절단 해쇄하며 종이펄프와 1 : 4의 비율로 혼합하고, 여기에 열경화성 수지 결착제의 수용액을 혼합하여 액상페놀수지와 혼합한 다음 이들 혼합물에 30-35%의 수분이 함유되도록 면압(10kg/cm2)으로 압착시킨 다음 하트 프레스상에서 14kg/cm2의 면압으로 150℃에서 30분간 가열압착하며, 또 단섬유(면섬유)를 3-4mm로 절단 해쇄하여 이것과 펄프를 각각 40wt%와 60wt%로 혼합시킨 후 액상 페놀수지 10wt%와 혼합시켜 이들의 혼합물 전체중량에 대하여 석고 20wt%와 염화메틸롤 5wt%를 첨가시켜 면압(5kg/cm2)으로 압착시키고 100℃에서 50분간 가열 건조한 다음 하트 프레스상에서 스테인레스제 부착 평철망상에 삽입시켜 면압(17kg/cm2)으로 가압온도 180℃에서 30분간 가열시킨 단섬유와 펄프를 이용하여 판재를 제조하여 극히 가볍고 강도가 높은 물성을 갖도록 한 특성을 가지며, 이에 페펄프의 미세한 조각과 단섬유에 폴리프로필렌 등의 화이버를 첨가시켜 가압가열하여 내열성이 강한 열가소성 판재류를 얻을 수 있고, 염화메틸롤 또는 인산소다 등을 소량 첨가하면 방염성이 우수하도록하며, 위 단섬유와 페펄프 또는 펄프의 혼합물과 석면 또는 글라스울을 첨가하면 가볍고 내열성이 향상되며, 위 단섬유와 페펄프로 만든 판재류 상부에 석고로 도포하거나 미장처리를 할 때 우수한 난연성이 있는 미장건재 및 가구제품의 원재료가 되도록 하는 등 부가적 특성을 구비함을 목적으로 한 판재류의 제조방법을 제공하는데 있다.In the present invention, the short fibers (chemical fibers and cotton fibers) are mixed in a 1: 1, cut and pulverized to a length of 3-4 mm, mixed in a ratio of 1: 4 with paper pulp, and mixed with an aqueous solution of a thermosetting resin binder. After mixing with the liquid phenolic resin, the mixture is pressed with a surface pressure (10 kg / cm 2 ) to contain 30-35% of water, and heat-pressed at 150 ° C. for 30 minutes at a surface pressure of 14 kg / cm 2 on a heart press. Cut and disintegrate the short fibers (cotton fibers) into 3-4mm, mix them with 40wt% and 60wt%, and mix them with 10wt% of liquid phenolic resin, and 20wt% gypsum and 5wt% methyl chloride based on the total weight of the mixture. % Was added and pressed at a surface pressure (5 kg / cm 2 ), heated and dried at 100 ° C. for 50 minutes, and then inserted into a stainless steel flat wire mesh on a heart press and heated at 180 ° C. for 30 minutes at a pressure of 17 kg / cm 2 . Using short fibers and pulp By manufacturing the sheet material, it has the characteristics of having extremely light and high physical properties, and by adding a fiber such as polypropylene to the fine pieces of pepulp and short fibers, it can be heated under pressure to obtain a thermoplastic sheet having high heat resistance. Adding a small amount of methylol or sodium phosphate to improve flame resistance, and adding a mixture of gastric short fibers and pulp or pulp and asbestos or glass wool improves lightness and heat resistance. The present invention provides a method of manufacturing a plate material for the purpose of having additional characteristics such as to make the raw materials of plastering and furniture products having excellent flame retardancy when applied with plaster or plastering process.
일반적으로 판재류는 그 사용목적에 따라 다르나, 그 재질이 구비하여야 할 특성으로는 그 재질의 중량이 가벼워야 하며, 내열성이 우수하여야 하고 평판소재로 사용할 때 성형성이 용이하여야 하며 인장 강도 및 절곡강도가 우수하여야 한다.In general, plate materials vary depending on the purpose of use, but the material should be light in weight, excellent in heat resistance, easy to form when used as flat plate material, tensile strength and bending strength. Should be excellent.
또 가격을 저렴하게 제조할 때에는 그 제조 시설이 소규모이며 작업이 단순하여야만 경제적인 잇점이 있다.In addition, when manufacturing at low cost, the manufacturing facilities are economical only if the manufacturing facilities are small and the operation is simple.
이와 같이 판재류를 제조함에 있어서는 그 제조되는 판재류의 물성 및 경제적인 점을 감안하여 연구를 시도한 결과 본 발명을 완성하였다.As described above, the present invention was completed in consideration of the physical properties and economical points of the manufactured sheet materials in manufacturing the sheet materials.
본 발명의 제조방법을 상술하면 다음과 같다.The manufacturing method of the present invention will be described in detail as follows.
단섬유(화학섬유와 면섬유)를 1 : 1로 혼합하고 3-4mm로 절단해쇄시켜 펄프 또는 폐펄프와 1 : 4의 비율로 혼합시킨 후 액상 페놀수지와 혼합하여 이들의 혼합물을 30-35%의 수분이 함유되도록 면압(10kg/cm2)으로 압착시킨 다음 하트프레스상에서 14kg/cm2의 면압으로 150℃에서 30분간 가열압착하며 또한, 단섬유(면섬유) 3-4mm로 절단해쇄시킨 후 이를 그 펄프와 각각 40wt%와 60wt%로 혼합시키고 액상 페놀수지 10wt%와 혼합시켜 이들의 혼합물 전체중량에 대하여 석고 20wt%와 염화메틸롤 5wt%를 첨가시켜 면압(5kg/cm2)으로 압착시킨 다음 100℃에서 50분간 가열 건조한 다음 하트프레스 상에서 스테인레스제 부착 평철망상에 삽입시켜 면압(17kg/cm2)으로 가압시키고 180℃에서 30분간 가압 가열시킨다.Short fibers (chemical fiber and cotton fiber) are mixed in 1: 1, and cut into 3-4mm, mixed with pulp or waste pulp at a ratio of 1: 4, and mixed with liquid phenolic resin to mix 30-35 After pressing with cotton pressure (10kg / cm 2 ) to contain% moisture, heat pressing at 150 ° C. for 30 minutes at a surface pressure of 14kg / cm 2 on a heart press, and cutting and crushing into short fibers (cotton fibers) 3-4mm. It was then mixed with the pulp at 40wt% and 60wt% respectively, mixed with 10wt% liquid phenolic resin, and 20wt% gypsum and 5wt% methyl chloride were added to the total weight of the mixture, followed by pressing at a surface pressure (5kg / cm 2 ). After drying at 100 ° C. for 50 minutes, it was inserted into a stainless steel flat mesh on a heart press, pressurized to a surface pressure (17 kg / cm 2 ), and heated at 180 ° C. for 30 minutes.
즉,단섬유와 펄프의 혼합비를 1 : 4의 비율로 혼합할 때 제품에 미치는 강도가 강하여지며 제품의 표면이 매끄럽고 경량이며 내열성이 강하고 혼합시간을 단축시킬 수 있다.That is, when the mixing ratio of short fibers and pulp in a ratio of 1: 4, the strength on the product becomes stronger, and the surface of the product is smooth, lightweight, heat resistant, and the mixing time can be shortened.
또 처리되는 단섬유로는 화학섬유와 면섬유를 각각 사용할 수가 있어 사용분야에 따라서 이들의 섬유를 일정비율로 혼합시킨 혼합섬유를 사용할 수도 있다.Further, as the short fibers to be treated, chemical fibers and cotton fibers can be used, respectively, and mixed fibers obtained by mixing these fibers at a predetermined ratio may be used depending on the field of use.
여기서 이들의 섬유를 일정한 길이 3-4mm로 절단시켜 해쇄(解碎)시킴으로써 액상페놀수지와 혼합처리 조작을 능률적으로 수행할 수 있도록 한 것이다.Here, these fibers were cut into 3-4 mm in length to be crushed to be able to efficiently perform the mixing treatment operation with the liquid phenolic resin.
또 결착제로서 각종 수지가 있으나, 실험결과 액상 페놀수지를 사용함으로써 양호한 결착효과를 기대할 수가 있다.Moreover, although there are various resins as a binder, a good binding effect can be expected by using a liquid phenol resin as a result of experiment.
즉, 단섬유와 펄프간의 결착을 매우 좋게 결착시킴으로써 강도 및 경량으로 할 수 있는 판재로서의 효과를 갖도록 한다.That is, by binding the short fiber and the pulp very well, it is possible to have an effect as a plate material which can be made strength and light weight.
이에 또, 혼합처리 된 혼합물에 있어서 일정량의 수분을 함유 유지하도록 일정한 면압으로 압착시키는 기술적 수단이 본 발명의 특징이다.In addition, the technical means for compressing at a constant surface pressure to maintain a certain amount of moisture in the mixed mixture is a feature of the present invention.
본 발명의 판재류 제조공정은 이들의 처리공정에서 혼합조건과 혼합물의 일정한 수분함량이 유지되도록 압착시키는 처리방법에 그 기술상의 어려움이 있는 바, 제1단계공정은 가압되면서 20%미만의 수분 탈수가 행하여지고, 제2단계는 하트프레스 상하판에 부착된 열판에 의해 탈수압착 된 혼합물이 가열되어 증기를 발생시키면서 건조가 행하여진다.The sheet material manufacturing process of the present invention has a technical difficulty in the treatment method for compressing the mixing conditions and the constant moisture content of the mixture in the treatment process of the present invention. In the second step, the mixture dehydrated and pressed by a hot plate attached to the upper and lower hearts presses is heated and dried while generating steam.
제2단계 공정은 매우 까다로운 과정으로 열판의 온도를 150℃ 내지 170℃ 고온으로 가열하면 기화된 수증기의 배출이 일어나는데 가압된 상태에서 별도의 배출구가 없는 관계로 배출되는 수증기의 배출이 문제가 된다.The second step is a very demanding process. When the temperature of the hot plate is heated to a high temperature of 150 ° C. to 170 ° C., vaporization of vaporized water occurs. However, there is a problem in that vaporized water is discharged in a pressurized state because there is no separate discharge port.
프레스의 압력 이내에 발생되는 수증기를 원활하게 배출시키기 위한 방법은 프레스 상판에 부착된 열판과 판재혼합물 사이에 스테인레스제 철망을 삽입시키는 방법이다.A method for smoothly discharging water vapor generated within the pressure of a press is a method of inserting a stainless steel wire between a hot plate attached to a press top plate and a plate mixture.
또한 초기에 발생된 수증기는 프레스 압력을 하강시켜 배기시키는 조작을 2, 3회 시행하면 판재의 증발 건조과정의 시간은 단축된다.In addition, if the steam generated at the beginning of the operation by lowering the press pressure and exhausting two or three times, the time for the evaporation drying process of the plate is shortened.
제3단계 고정으로서는 결착제의 경화과정인데 페놀수지의 열경화는 150℃-170℃에서 120℃로 완료되는데 열경화는 온도와 밀접한 관계가 있어 가열온도를 높히면 경화시간은 단축되나 성형된 판재의 표면은 매끄럽지 못하고 또한 펄프등의 조직에 탄화가 일어나는 것과 화학섬유의 분해온도나 용융온도 이상에서는 성형물이 원하는 형상이나 강도를 유지하지 못하게 된다.The third step of fixing is the curing process of the binder. The thermosetting of the phenol resin is completed from 150 ℃ -170 ℃ to 120 ℃. The heat curing is closely related to the temperature, so the curing time is shortened by increasing the heating temperature. The surface of is not smooth and carbonization occurs in the tissues such as pulp, and the molding may not maintain the desired shape or strength above the decomposition or melting temperature of chemical fibers.
따라서 판재 원료의 중앙부에 위치한 페놀수지의 경화까지 완료되도록 충분한 시간을 부여하는 것이 매우 중요하다.Therefore, it is very important to give enough time to complete the curing of the phenol resin located in the center of the plate material.
더 나가서, 단섬유(면섬유)를 3-4mm로 절단 해쇄시킨 후 펄프 또는 폐펄프의 일정비율 1 : 4 비율로 혼합시킨 다음 액상 페놀수지 일정량과 혼합시키되, 이들의 전체중량에 대하여 일정량의 석고 20wt%와 염화메틸롤을 첨가시켜 일정한 면압으로 압착 탈수한 후 특정온도에서 일정시간 가열 건조시킨 다음 하트프레스상에서 스테인레스제 부착평철망에 삽입하고, 일정한 면압(14kg/cm2)으로 150℃ 이상에서 가열 가압시켜서 성형되므로 방수성과 불연성이 강하게 되며, 더우기 강도가 우수한 각종 두께의 판재를 얻을 수가 있다.Further, the short fibers (cotton fibers) are cut into 3-4 mm, pulverized, and mixed in a ratio of 1: 4 of pulp or waste pulp, and then mixed with a predetermined amount of liquid phenolic resin, with a certain amount of gypsum 20wt based on the total weight thereof. After pressing and dehydrating with constant surface pressure by adding% and methyl chloride, heat-drying at a specific temperature for a certain time, and then inserting into a stainless steel flat wire mesh on a heart press, and heating at a constant surface pressure (14kg / cm 2 ) or more at 150 ° C. Since it is press-molded, it becomes strong in water resistance and incombustibility, and furthermore, the board | plate material of various thickness excellent in intensity | strength can be obtained.
여기서 바람직한 것은 조성물의 배합비율과 제조공정 및 가열가압 온도가 특수한 조건으로 조성을 이루어지게 된다. 더우기 바람직한 조건은 단섬유와 펄프 및 액상 페놀수지 혼합비를 4 : 6 : 1 로 하며 그 전체중량에 대하여 20%의 석고와 염화메틸롤 5%를 첨가시켜 면압(5kg/cm2)에서 가압하고 100℃에서 50분간 가열 건조시킨다.Preferred here is the compounding ratio of the composition and the manufacturing process and heating pressurization temperature is made of the composition under special conditions. Furthermore, the preferred condition is a mixture of short fiber, pulp, and liquid phenolic resin in a ratio of 4: 6: 1, and pressurized at a surface pressure (5kg / cm 2 ) by adding 20% of gypsum and 5% of methyl chloride to the total weight thereof. Heat-dry at 50 degreeC for 50 minutes.
이와 같이 본 발명에 의한 판재는 그 재질이 가볍고 인장강도 및 절곡강도가 우수하고 가격이 저렴하므로 다량 생산할 수 있는 효과가 있다. 또한 판재의 성형 가공이 우수하므로 각종 판재로 사용할 수 있고, 특히 자동차 내장재로 사용하는데 적합하다.As described above, the plate according to the present invention is light in material, excellent in tensile strength and bending strength, and inexpensive in price, thereby producing a large amount.
