Abstract
Description
본 발명은 석목상, 암기상(岩肌狀), 수피상(樹皮狀), 토벽상 혹은 목기상 등의 표면외관을 가진 시트 성형용 조성물 및 그것을 사용한 시트의 제조방법에 관한다.The present invention relates to a composition for forming a sheet having a surface appearance such as stone, memorized, bark, earth wall or wood, and a method for producing a sheet using the same.
종래부터 이런종류의 시트는 수경성무기 시멘트분말, 수성 에멀젼, 시르스바룬 등의 발포체 분자 및 탄산칼슘등의 비수경성 무기질분말을 각각 함유하는 조성물과 이러한 조성물에 수성 슬러리를 성형한 후 95℃∼160℃로 가열하여 경화, 건조하게 하는 것이 제안되어있다. 이러한 종래의 시트는 시트성형 시 난형성이 양호하며, 수피(樹皮)등 원하는 외관과 비슷한 표면 외관을 나타내는 것 뿐만 아니라, 옥외에서 토목용도 등에 사용하는 때에는 동결 안정성, 접히고 뒤틀리는 것에 대한 저항성이 우수한 효과를 가지고있는 것이다.Conventionally, this type of sheet is composed of a composition containing a hydraulic inorganic cement powder, an aqueous emulsion, a foam molecule such as Sirs-barun, and a non-hydro inorganic inorganic powder such as calcium carbonate, respectively, and an aqueous slurry of such a composition, followed by molding an aqueous slurry. It is proposed to heat it to ° C to cure and dry it. Such a conventional sheet has good difficulty in sheet forming, and exhibits a surface appearance similar to a desired appearance such as bark, as well as excellent freeze stability and resistance to folding and warping when used in civil engineering outdoors. Would have an effect.
먼저 첫째로, 성형시트는 수경성무기질 시멘트를 기본재료로 하기 때문에 그 경화, 건조는 시트의 두께가 5mm∼10mm의 경우, 140℃에서 60분, 8mm∼15mm의 경우, 140℃에서 5시간이 필요하다. 이처럼 경화, 건조시의 가열온도를 140℃로 대단히 높게 설정할 필요가 있기 때문에, 열원의 문제, 열원의 에너지 다소비, 혹은 안전성 등에 문제가 있을 뿐 아니라 시트의 두께가 두꺼울수록 경화, 건조시간이 길어지며, 생산효율이 대단히 나쁘다.First, since the molding sheet is made of hydraulic inorganic cement as a base material, the hardening and drying require 60 minutes at 140 ° C. for 5 mm to 10 mm, and 5 hours at 140 ° C. for 8 mm to 15 mm. Do. Since the heating temperature at the time of hardening and drying needs to be set very high at 140 degreeC, it is not only a problem of a heat source, the energy consumption of a heat source, or a safety | security, but a thicker sheet has a long hardening and drying time. The production efficiency is very bad.
둘째로, 다량의 수경성무기질 시멘트를 기본재료로 하기 때문에 수경성무기질 시멘트의 수화반응 과정에서 다량의 수산화칼슘이 생성되고, 이것이 콘크리트표면에 용출되어 공기 중에 탄산가스와 반응하여 백화 생성이 쉽다.Second, since a large amount of hydraulic inorganic cement is used as a base material, a large amount of calcium hydroxide is produced during the hydration reaction of the hydraulic inorganic cement, which is eluted on the surface of the concrete and reacts with carbon dioxide gas in the air to easily produce whitening.
셋째로, 다량의 수경성무기질 시멘트를 사용하기 때문에 미수화반응분 시멘트가 잔류되기 쉽고, 더 나아가서 장기 침수시에는 굳게 되어 탄성을 상실하기 쉽다.Third, since a large amount of hydraulic inorganic cement is used, unhydrated cement is likely to remain, and furthermore, it becomes hard when it is immersed for a long time and loses elasticity.
본 발명의 석목상 시트 등 시트 성형용 조성물을 이용하여 시트를 성형하는 데에는 적당한 함수상태의 수성 슬러리 혼합물을 석목상 등 원하는 굴곡,모양을 가진 틀에 바르거나 흘러들게해서 성형시킨다. 성형이 완료되면 틀에 놓인 상태에서 생산성을 좋게 하기 위해 30℃∼70℃의 온도에서 가열, 건조하여 경화시킨다.In forming the sheet using the composition for forming a sheet such as the granular sheet of the present invention, an aqueous slurry mixture of a suitable water-containing state is formed by applying or flowing into a mold having a desired curvature or shape, such as a granite sheet. When the molding is completed, it is cured by heating, drying at a temperature of 30 ℃ to 70 ℃ to improve the productivity in the state placed in the mold.
경화된 시트 위에 그물(fiberglass mesh)를 얹은 다음 수성 슬러리 혼합물을 다시 바르거나 흘러 들게 하여 다시 한번 가열, 건조하여 경화시켜서 뒷면을 완성한다.A fiberglass mesh is placed on the cured sheet and then the aqueous slurry mixture is reapplied or flowed and once again heated, dried and cured to complete the back side.
이렇게 하여 성형 완성된 시트는 한층 돌결같아 보이며, 강도를 향상시키기 위하여 겉표면에 적당히 분말상 착색제를 살포하거나 시멘트계 착색도료, clear도료 등을 바른다.In this way, the molded sheet looks more grainy, and in order to improve the strength, a powdery colorant is appropriately sprayed on the surface, or a cement-based coloring paint or a clear paint is applied.
본 발명에 있어서의 기본재료는 잠재 수경성무기질 분말과 수경성 시멘트로 한다.The base material in this invention is a latent hydraulic inorganic powder and hydraulic cement.
잠재 수경성 무기질 분말 50∼93 중량부와 수경성 시멘트 7∼50중량부로 구성되는 기본재료 100 중량부, 포조란반응성 무기질분말 0∼50중량부, 비수경성 무기질분말 0∼300중량부, 수화반응 지연제 0.5∼5.0 중량부, 수성수지 에멀젼 (수지 고형 분량)40∼100 중량부 를 각각 함유하는 조성물이 된다. 그리고 이러한 조성물을 수성슬러리화 한 후, 필요한 형상의 틀에 바르거나 속에 흘려넣어 건조반응을 시킴으로써 제조하는 것이다.100 parts by weight of the base material consisting of 50 to 93 parts by weight of latent hydraulic inorganic powder and 7 to 50 parts by weight of hydraulic cement, 0 to 50 parts by weight of pozzolan-reactive inorganic powder, 0 to 300 parts by weight of non-hydraulic inorganic powder, retarding hydration reaction 0.5 to 5.0 parts by weight and 40 to 100 parts by weight of an aqueous resin emulsion (solid resin amount) are obtained. Then, the aqueous slurry is prepared by applying it to a mold of a required shape or pouring it into a mold to carry out a drying reaction.
본 발명은 잠재 수경성 무기질 분말을 중심으로 수경성 시멘트와 수성 수지 에멀젼을 섞어, 백화가 거의 생기지않으며, 유연성, 내온수성에 탁월하며, 게다가 생산효율이 좋은 석목상 시트 등의 시트 성형용 조성물 및 그것을 사용한 시트의 제조방법을 제공하려 하는 것이다.The present invention mixes a hydraulic cement and an aqueous resin emulsion with a focus on latent hydraulic inorganic powder, hardly whitening, excellent in flexibility and hot water resistance, and also has a composition for forming a sheet such as a granite sheet having good production efficiency and using the same. It is to provide a method for producing a sheet.
그리고 상기의 잠재 수경성 무기질 분말로써는 일반적으로 용광로 슬래그를 적당하게 사용할 수 있다. 이러한 용광로 슬래그는 용광로에서 배출되는 용융슬래그를 물로 급랭하여 고석회 아르미노실리케이트글라스질화 한 것으로 그 화학성분은 CaO, Al2O3, MgO등으로 구성되어 잠재 수경성 즉, 알카리성 자극제의 존재하에 수경성을 나타내는 것이다.And as said latent hydraulic mineral powder, a furnace slag can be used suitably generally. The furnace slag is quenched molten slag discharged from the furnace with water to quench high lime aminosilicate glass, and its chemical component is composed of CaO, Al2O3, MgO, etc., which indicates hydrophobicity in the presence of latent hydraulic, that is, alkaline stimulant.
기본 재료로하는 잠재 수경성 무기질 분말은 기본재료100중량부 중 50∼93중량부 의 비율로 배합한다. 그리고 이러한 배합비율이 50중량부 이하의 경우에는 백화현상이 강하게 일어나며, 장기 침수 시에는 굳게 된다. 또, 93중량부를 넘을 경우에는 수경성이 저하되며 더 나아가서는 내수성도 저하될 뿐 아니라, 온수침하에 있어서는 피막의 팽창을 일으킨다.The latent hydraulic inorganic powder used as the base material is blended at a ratio of 50 to 93 parts by weight in 100 parts by weight of the base material. When the compounding ratio is 50 parts by weight or less, whitening phenomenon occurs strongly, and becomes hard during prolonged immersion. In addition, when it exceeds 93 parts by weight, the hydraulic properties are lowered, and further, the water resistance is also lowered, and in addition, the film is expanded in hot water settling.
또한, 기본재료로서의 수경성 시멘트는 Portland cement, 조강cement, 고로cement, 실리카cement, Flyash cement ,백색cement, 알루미나(alumina)cement, 토마스 세라믹cement , 베통(beton)원소 등의 토양고화 cement등을 단독으로 또는, 이것들을 필요에 따라 적당하게 조합시켜 사용한다. 수경성 시멘트는 기본재료 100중량부 중에서, 7∼50중량부의 비율로 배합시킨다. 이때,사용하는 수경성 시멘트 가운데 고로slag, 실리카, Flyash는 각각 잠재 수경성물 즉, pozzloanic 반응 성분으로써 계산한다. 작업할 때의 배합비율이 7중량부 이하의 경우에는 알칼리 자극제로서의 촉진반응제의 움직임 또는 시멘트 그 자체의 효과가 적고, 결과적으로 수화반응이 약하게 되어 내수성의 저하를 초래한다. 또한, 50중량부를 넘어서는 경우에는 백화현상이 생기기 쉽고, 장기간 물에 침수시 딱딱하게 된다.In addition, the hydraulic cement as a base material is Portland cement, crude steel cement, blast furnace cement, silica cement, fly cement, white cement, alumina cement, Thomas ceramic cement, soil solidification cement such as Beton element. Or these are used combining suitably as needed. Hydraulic cement is mix | blended in the ratio of 7-50 weight part in 100 weight part of base materials. At this time, blast furnace slag, silica, and fly ash of the hydraulic cements used are calculated as potential hydraulic substances, that is, pozzloanic reaction components. When the blending ratio is 7 parts by weight or less when working, the movement of the accelerator as an alkali stimulant or the effect of the cement itself is small, and as a result, the hydration reaction becomes weak, resulting in a decrease in water resistance. In addition, when the amount exceeds 50 parts by weight, whitening is likely to occur, and becomes hard when immersed in water for a long time.
본 발명에 관련된 pozzloanic 반응성 무기질 분말로서는 Flyash, 실리카흄(hume), 왕겨재 등의 인공 pozzloanic, 혹은, 시라스(모래톱),백토,화산재에서 기인하는 천연 pozzloanic을 미분말상으로 하여 사용하며, 통상 Flyash를 적당히 사용한다. 그리고, 보통의 시라스는 pozzloanic반응성 무기질로써보다 오히려 필러(filler)로써 작용한다. 그리고 사용되는 pozzloanic반응성 무기질 분말은 주로 모래로 사용하지만, 부차적으로 기본재료 중 잔류 알칼리성분과 반응하여 수화물이 생성된다. 사용되는 pozzloanic 반응성 무기질분말은 기본재료 100중량부에 대해 0∼50중량부, 30중량부 이하가 바람직하며, 배합비율이 50중량부 를 넘는 경우에는 경화반응이 늦기 때문에 시트의 견고성이 안정되지 않을 뿐 아니라, Flyash의 불순물에 의한 반응이상 또는 착색을 발생시킨다.As the pozzloanic reactive inorganic powder of the present invention, artificial pozzloanic such as Flyash, silica fume, rice hull, or natural pozzloanic derived from syras (sand), clay, volcanic ash are used as fine powder, and normally Flyash is suitably used. use. And ordinary syras act as fillers rather than as pozzloanic reactive minerals. The pozzloanic reactive inorganic powders used are mainly used as sand, but secondaryly react with residual alkali in the base material to produce hydrates. The pozzloanic reactive inorganic powder to be used is preferably 0 to 50 parts by weight and 30 parts by weight or less with respect to 100 parts by weight of the base material. In addition, it causes abnormal reaction or coloring due to impurities of fly ash.
비수경성 무기질 분말의 예를 들면, 탄산칼슘, 규사, 탈크(talc), clay, 세라믹스분자, 그 外에 각종 무기질안료,무기질 착색용안료 등을 들 수 있다.Examples of the non-hydraulic inorganic powders include calcium carbonate, silica sand, talc, clay, ceramic molecules, and other inorganic pigments and inorganic coloring pigments.
비수경성 무기질 분말은 반드시 필요한 성분은 아니지만, 필러(filler)로써 배합하는 것이 바람직하다. 그리고 그 배합비율은 잠재 수경성 무기질 분말 100중량부에 대하여 0∼300중량부, 가장 좋은 것은 30∼l50중량부이다. 사용되는 배합비율이 너무 많을 경우에는 시트가 딱딱하고 부서지기 쉬우며, 특히 물에 침전하면 지나치게 딱딱한 것이 된다.The non-hydraulic inorganic powder is not a necessary component, but is preferably blended as a filler. And the compounding ratio is 0-300 weight part with respect to 100 weight part of latent hydraulic mineral powder, and the best thing is 30-50 weight part. If the blending ratio used is too large, the sheet is hard and brittle, especially when precipitated in water, it becomes too hard.
본 발명에 있어서 수화 반응 지연제는 특히, 가온하에서의 건조 초기에 수분이 많을 경우 시멘트의 수화 반응을 억제 지연시키며 급속한 반응에 의한 시트의 부러짐이나 탄성의 低下 등을 방지하고 안정된 수화반응을 일으키게 한다. 관련 수화 반응 지연제로는 글루콘산(gluconic acid)나트륨이나 옥살산나트륨을 사용하며 그 배합비율은 기본재료 100중량부에 대해 적당한 비율은 0.5∼5.O중량부이다. 배합비율이 0.5중량부 이하의 경우, 수화 반응 지연 효과가 거의 없으며, 5.0중량부를 넘는 경우에는 수화반응 지연효과가 커 수화반응에 의한 초기의 목적물을 얻을 수 없게 된다.In the present invention, the hydration reaction retarder inhibits the hydration reaction of cement, especially when there is a lot of moisture at the beginning of drying under warming, and prevents breakage of the sheet due to rapid reaction or deterioration of elasticity, and causes stable hydration reaction. As a related hydration retarder, sodium gluconic acid or sodium oxalate is used. The mixing ratio is 0.5 to 5.0 parts by weight based on 100 parts by weight of the base material. When the blending ratio is 0.5 parts by weight or less, there is almost no effect of delaying the hydration reaction, and when it exceeds 5.0 parts by weight, the effect of delaying the hydration reaction is large and the initial target product by the hydration reaction cannot be obtained.
또한, 수성수지 에멀젼(emulsion)으로는 예를 들어, 아크릴산 2-에틸헥실,아크릴산 n·butyl, 아크릴산 에틸, 아크릴산 이소프로필(isopropyl), 메타크릴(methacrylate)산2에틸헥실, 아크릴산n·propyl, 메타크릴산 n·butyl, 초산비닐, 아크릴산, 메타크릴산n 프로필, 스틸렌, 메타크릴산메틸, 메타크릴산, 무수말레이(maleic)산, 이타곤산, 아크릴산아미드(amide), 메타크릴산에틸, 에틸렌, 부타디엔(butadiene)등에서 선택된 불포화 단량체의 1종류 또는 2종류 이상을 유화중합시켜 얻어지는 homo중합체 또는 공중합체의 에멀젼(emulsion), 그 위에 중합체에멀젼(emulsion)의 2종류 이상의 혼합물이 사용된다. 또, 수성epoxy에멀젼과 같은 경화성수지의 수성에멀젼도 사용이 가능하다.As the aqueous resin emulsion, for example, 2-ethylhexyl acrylate, n-butyl acrylate, ethyl acrylate, isopropyl acrylate, 2ethylhexyl methacrylate, n-propyl acrylate, N-butyl methacrylate, vinyl acetate, acrylic acid, n-methacrylate propyl, styrene, methyl methacrylate, methacrylic acid, maleic anhydride, itaconic acid, amide acrylate, ethyl methacrylate, Emulsions of homopolymers or copolymers obtained by emulsion polymerization of one or two or more kinds of unsaturated monomers selected from ethylene, butadiene and the like, and mixtures of two or more kinds of polymer emulsions are used thereon. It is also possible to use an aqueous emulsion of a curable resin such as an aqueous epoxy resin.
또한, 우레탄에멀젼, 우레탄수용액, 실리콘에멀젼도 사용할 수 있다.Moreover, urethane emulsion, urethane aqueous solution, silicone emulsion can also be used.
아크릴산 에스테르(ester)스틸 공중합체 수지의 수성 에멀젼이거나 관련된 수성수지 에멀젼의 Tg는 5도 이하가 좋으며, 적당한 온도는 -20℃∼-50℃이다. 그리고 이 수성수지 에멀젼은 기본재료 100중량부에 대해 40∼100중량부(수지고형분량)의 비율로 배합하는 것이 좋다. 배합비율이 너무 높으면 부드러운 것은 좋지만, 표면접착성이 강하게 되어 오염되기 쉬우며, 또 성형시 경화, 건조시간, 특히 건조시 필요한 시간이 장시간 걸리게 되어 생산성이 저하된다. 또한, 배합비율이 너무 낮으면 석목상 시트 등에서의 시트가 딱딱해지게 되며 부서지기 쉽다.The aqueous emulsion of the acrylic ester steel copolymer resin or the Tg of the related aqueous resin emulsion is preferably 5 degrees or less, and a suitable temperature is -20 ° C to -50 ° C. And this aqueous resin emulsion is good to mix | blend in the ratio of 40-100 weight part (residual solid content) with respect to 100 weight part of base materials. If the blending ratio is too high, the soft one is good, but the surface adhesiveness is strong, and it is easy to be contaminated, and the hardening and drying time during molding, especially the time required for drying, take a long time, and the productivity is lowered. In addition, when the blending ratio is too low, the sheet in the granular sheet or the like becomes hard and brittle.
더구나, 본 발명에 있어서는 잠재 수경성 무기질 분말이 중심이기 때문에 알칼리성 자극제가 필요하며, 관련 알칼리성 자극제로서는 수경성 시멘트의 알칼리성물질이 작용되어지며, 수경성 시멘트의 배합량이 적은 경우에는 알칼리성 자극제의 병용이 필요하며, 이에 의해 보다 안정된 수경반응을 진행시킬 수 있다. 관련 알칼리성 자극제로는 수산화칼슘, 수산화나트륨, 케이산나트륨, 메타게이산나트륨 등 강 알칼리성 물질을 사용한다. 또한, 관련 알칼리성 자극제로는 용광로slag의 glass구조를 파괴하여 CaO,SiO2,Al2O3,MgO의 용출을 촉진시켜 액상 중의 각 이온 농도를 높이고, 수화물을 계속적으로 적출시키는 작용을 한다. 즉, 용광로slag의 glass질을 구성하고 있는 불규칙한 -O-Si-O-Al-O-의 삼차원망상구조체의 쇠사슬모양(鎖狀)결합이 알칼리성 자극제의 강알칼리 때문에 절단되어 그 망목 구조내에 들어있는 Ca Mg Al등의 이온이 용이하게 용출되고 용출된 각 이온이 칼슘실리케이트 수화물, 칼슘 알루미네이트 수화물을 생성하여 경화하게 된다.Furthermore, in the present invention, an alkaline stimulant is required because the latent hydraulic inorganic powder is the center, and an alkaline substance of hydraulic cement is applied as the related alkaline stimulant, and when the amount of the hydraulic cement is small, the combination of the alkaline stimulant is necessary. Thereby, a more stable hydroponic reaction can be advanced. Relevant alkaline stimulants include strong alkaline substances such as calcium hydroxide, sodium hydroxide, sodium cate, sodium metagarate. In addition, the related alkaline stimulant breaks the glass structure of the furnace slag to promote the elution of CaO, SiO 2, Al 2 O 3, MgO to increase the concentration of each ion in the liquid phase and to continuously extract the hydrate. That is, the chain-like bonds of the irregular -O-Si-O-Al-O- three-dimensional network structure constituting the glass of the furnace slag are cut due to the strong alkali of the alkaline stimulant, and the Ca contained in the mesh structure. Ions such as Mg Al are easily eluted, and each of the eluted ions generates and hardens calcium silicate hydrate and calcium aluminate hydrate.
또, 관련 알칼리성 자극제는 용광로slag의 표면을 PH1, 2 전후까지 상승시키는 것이 좋으며, 일단 반응이 시작되면 용광로slag 자체에서 용출하는 알칼리 성분에 의해 PH의 지속이 가능하다. 때문에 알칼리성 자극제는 용광로slag 100 중량부에 대해 0∼15 중량부의 배합비율로 첨가하고 배합비율이 15중량부를 넘어서는 경우에는 과다한 알칼리 분에 의해 백화가 생기거나 내수성의 저하, 과잉 알칼리의 용출에 의한 환경오염 등을 초래 시킬 위험이 있기 때문에 바람직하지 않다. 또, 수경반응을 진행하지 않으면, 동결 사이클(-20℃ 대기중 동결 5℃ 수중융해)에 대한 저항성이 저하된다.In addition, it is preferable to raise the surface of the furnace slag to about PH1 and 2 before and after the related alkaline stimulant, and once the reaction is started, the PH can be sustained by the alkaline component eluting from the furnace slag itself. Therefore, alkaline stimulants are added at a blending ratio of 0 to 15 parts by weight with respect to 100 parts by weight of the furnace slag, and when the blending ratio is more than 15 parts by weight, whitening occurs due to excessive alkali content, a decrease in water resistance, or an environment caused by excessive alkali elution. It is not preferable because there is a risk of causing contamination. In addition, if the hydroponic reaction is not carried out, the resistance to the freezing cycle (freezing at -20 ° C and freezing at 5 ° C in water) is lowered.
본 발명은 상술한대로 구성되어 있기 때문에 수경성 시멘트를 중심으로 수성수지 에멀젼(emulsion)을 조합한 종래의 예에 비하여 잠재수경성 무기질분말을 중심으로 수경성 시멘트와 수성수지 에멀젼을 조합 시킨 것이기 때문에 백화(白華)를전혀 발생 시키지 않고 유연성(柔軟性), 내온수성에 뛰어나다. 더구나 생산효율이 좋아 석목상 시트 등 필요한 시트를 생성시키는 것이 가능하다.Since the present invention is constructed as described above, the combination of hydraulic cement and aqueous resin emulsion centered on the latent hydraulic inorganic powder, compared to the conventional example of combining an aqueous resin emulsion (emulsion) mainly on the hydraulic cement. It is excellent in flexibility and hot water resistance without generating at all. In addition, the production efficiency is good, it is possible to produce the necessary sheet, such as granite sheet.
