Description

목재 절삭용 수계 세정제 조성물{Aqueous detergent composition for wood cutting}Aqueous detergent composition for wood cutting

본 발명은 목재 절삭용 수계 세정제 조성물에 관한 것으로, 더욱 상세하게는 목재 절삭용으로 사용되는 금속의 세정에 사용되는 수계 세정제 조성물에 관한 것이다.The present invention relates to an aqueous detergent composition for cutting wood, and more particularly, to an aqueous detergent composition used for cleaning metals used for cutting wood.

목재를 절삭할 때에 레진산과 일부 소수성 물질이 절삭용 톱과 강한 흡착을 일으켜 표면에서 산화막과 오염물질이 형성되고 마찰열이 발생한다. 이러한 오염물질을 제거하기 위해 산성 세정제와 알카리성 세정제가 사용되어 왔으며, 산성 세정제로서 크롬산계나 불화수소산계 세정제가 주를 이루었다. 그러나, 이들 세정제는 유해물질을 함유하고 있기 때문에 크롬이나 불소를 사용하지 않는 세정기술이 발표되기도 하였다. 일본 특허공보 평3-50838호, 일본 특허공보 평3-65436호의 경우 불소 이온을 함유하지 않은 황산 또는 질산을 사용하였으나, 표면 손상과 함께 세정성이 저하되는 문제가 있었다. When cutting wood, resinic acid and some hydrophobic materials generate strong adsorption with the cutting saw, forming oxides and contaminants on the surface and generating frictional heat. Acidic cleaners and alkaline cleaners have been used to remove such contaminants, and chromic acid or hydrofluoric acid cleaners have been mainly used as acidic cleaners. However, since these cleaners contain harmful substances, cleaning techniques that do not use chromium or fluorine have been published. In Japanese Patent Laid-Open No. 3-50838 and Japanese Patent Laid-Open No. 3-65436, sulfuric acid or nitric acid that does not contain fluorine ions was used, but there was a problem of deterioration in cleaning with surface damage.

대한민국 공개특허 제1990-0001828호는 가성소다, 메타 또는 올소 규산소다, 트리에탄올아민에 알킬 글루코사이드계 비이온 계면활성제를 첨가한 강알카리성 투 명 액상 금속 세정제 조성물을 개시하고 있다. 그러나, 알칸올 아민류와 같은 유기 알카리성 세정제도 금속의 부식현상을 유발한다는 문제점이 있으며, 부식을 방지하기 위하여 알카리 금속 메타실리케이트나 1~3호 규산나트륨을 사용할 경우 부식방지 효과는 좋으나 장기 보관시 제품 내에서 침전을 일으키는 문제점이 있었다.Korean Patent Laid-Open Publication No. 1990-0001828 discloses a strongly alkaline transparent liquid metal detergent composition in which an alkyl glucoside-based nonionic surfactant is added to caustic soda, meta or olso silicate, and triethanolamine. However, organic alkaline cleaners such as alkanol amines also cause problems of corrosion of the metal.Also, alkali metal metasilicate or sodium salts 1-3 are good to prevent corrosion. There was a problem causing precipitation within.

또한, 공업용 탈지, 정밀가공 및 미세 가공된 구조물의 표면 또는 미세 틈새에 존재하는 오염물질을 제거할 때는 주로 오염물질에 대한 젖음성, 침투성 및 용해성이 우수한 프론계 용제 및 염소계 용제가 폭넓게 사용되었으나, 프론계 용제 및 염소계 용제는 뛰어난 세정효과를 나타내지만, 환경 규제로 인해 전세계적으로 그 사용량을 줄이고 있는 실정이며, 2010년 이후에는 사용금지 품목으로 구분되었다. 따라서, 목재 절삭용 톱날의 부식을 방지할 수 있고, 세정효과가 개선되며 친환경적인 목재 절삭용 수계 세정제 조성물을 필요로 하고 있는 실정이다.In addition, when removing the contaminants present on the surface of the industrial degreasing, precision processing and micro-fabricated structures or micro crevices, mainly used fluoro solvents and chlorine solvents excellent in wettability, permeability and solubility to contaminants, System solvents and chlorine solvents show excellent cleaning effects, but due to environmental regulations, they are being reduced worldwide. Since 2010, they have been classified as prohibited. Therefore, it is possible to prevent the corrosion of the saw blade for wood cutting, the cleaning effect is improved and environmentally friendly wood cutting aqueous cleaning composition is required.

상기의 문제점을 해결하기 위하여, 본 발명에서는 소수성 물질의 제거를 위해 프론계 및 염소계 용제를 사용하지 않으며, 부식을 방지할 수 있고 세정효과가 우수한 목재 절삭용 수계 세정제 조성물을 제공하는 것을 목적으로 한다.In order to solve the above problems, the present invention does not use a pron-based and chlorine-based solvent for the removal of hydrophobic substances, it is an object of the present invention to provide an aqueous cleaning composition for wood cutting that can prevent corrosion and excellent cleaning effect. .

상기의 목적을 달성하기 위하여, 본 발명은In order to achieve the above object, the present invention

이하 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.

본 발명은 알칼리 용액, 계면활성제, 금속부식 방지제, 및 용매를 포함하는 목재 절삭용 수계 세정제 조성물을 제공한다.The present invention provides an aqueous cleaning composition for wood cutting comprising an alkali solution, a surfactant, a metal corrosion inhibitor, and a solvent.

목재를 절삭할 때에는 피치트러블 (pitch trouble)에 의한 마찰열이 발생할 수 있으며, 이는 주로 레진산과 일부 소수성 물질에 의한 톱면에서의 강한 흡착에 기인한 것이다. 목재 수지의 주요 구성 성분인 레진산(예: abietic acid, pimaric acid)은 알코올류, 벤젠, 클로로포름, 에테르, 아세톤, 카본 디설파이드(carbon disulfide), 알칼리 수용액 등에 용해될 수 있다.When cutting wood, frictional heat due to pitch trouble may occur, mainly due to strong adsorption on the saw face by resin acid and some hydrophobic materials. Resin acid (eg abietic acid, pimaric acid), the major constituent of wood resins, can be dissolved in alcohols, benzene, chloroform, ether, acetone, carbon disulfide, aqueous alkali solution, and the like.

본 발명의 세정제 조성물은 상기 용해 특성에 근거하여 가성소다(NaOH) 또는 가성칼륨(KOH) 등을 이용하여 제조되는 고농도의 알칼리 용액을 포함한다. 상기 알칼리 용액에 용매로서 메탄올, 에탄올, 및 이소프로판올 중에서 선택된 한 종 이상의 알코올을 혼합하여 근본적으로 레진산에 대한 세정 특성을 개량할 수 있다. 또한, 상기 용매는 물을 포함할 수 있다. The detergent composition of the present invention contains a high concentration of alkaline solution prepared using caustic soda (NaOH) or caustic potassium (KOH) or the like based on the above dissolution characteristics. One or more alcohols selected from methanol, ethanol, and isopropanol as the solvent may be mixed with the alkaline solution to fundamentally improve the cleaning properties for the resin acid. In addition, the solvent may include water.

세정제 조성물에서 알코올은 레진산과 소수성 물질을 분산시키는 역할을 하며 이로 인해 알칼리와의 접촉면적을 극대화시켰으며, 알칼리에 의해 레진산은 레진산염을 형성하여 지용성 계면활성제로서 소수성 물질을 세정하는데 상승 효과를 나타낸다.In the cleaning composition, alcohol plays a role in dispersing resin acid and hydrophobic substances, thereby maximizing the contact area with alkali, and the resin forms a resinate by alkali, thereby synergistically cleaning the hydrophobic substance as a fat-soluble surfactant. .

또한, 세정제 중에 다량의 알코올을 함유하는 경우 화재의 위험성이 대두될 수 있으나 이러한 문제점을 보완하고 우수한 침투력을 유지할 수 있도록 용도에 따라 희석하여 사용할 수 있다.In addition, if the cleaning agent contains a large amount of alcohol may be a risk of fire, but may be diluted according to the use to compensate for this problem and maintain excellent penetration.

본 발명이 목재 절삭용 수계 세정제 조성물은 계면활성제를 포함한다. 계면활성제로는 당(sugar)계를 친수기로 하는 양친매성 물질(glyco-system amphiphilic substances, GAS) 또는 당계 계면활성제(glycol-system surfactants, GS)를 사용할 수 있다. 상기 예로 든 물질들은 친수기와 소수기의 양쪽 모두가 존재하는 유기물이다. 구체적으로는 알킬 글루코사이드, 이소프렌 글리세라이드, 또는 N-알칸오일-N-메틸글루코사미드를 들 수 있다.The water-based cleaning composition for cutting wood of the present invention includes a surfactant. As the surfactant, a sugar-based amphiphilic substance (glyco-system amphiphilic substances (GAS) or sugar-based surfactants (glycol-system surfactants, GS) can be used. The above mentioned materials are organic substances in which both hydrophilic and hydrophobic groups exist. Specifically, alkyl glucoside, isoprene glyceride, or N-alkanoyl-N-methylglucosamide is mentioned.

당(sugar)계를 친수기로 하는 양친매 물질로는 일반적으로 Krafft점(주어진 농도의 계면활성제를 용해시키기 위한 수용액계의 온도)이 높고, 난용해성의 물질이 많으므로 실용가능한 것이 적다. The amphiphilic material having a sugar-based hydrophilic material generally has a high Krafft point (temperature of an aqueous solution system for dissolving a surfactant of a given concentration), and there are few practically poorly soluble substances.

일부 실온에서 용해할 수 있는 알킬 글루코사이드계 비이온 계면활성제로는 octyl β-D-glucopyranoside, decyl 또는 dodecyl β-D-maltoside, octanoly-N-methylglucamide 등이 있고, octyl α-D-glucopyranoside, dodecyl β-D-cellobioside, N-octylgluconamide 등 대부분 실온에서 용해성이 극히 낮다.Alkyl glucoside nonionic surfactants that can be dissolved at some room temperature include octyl β-D-glucopyranoside, decyl or dodecyl β-D-maltoside, octanoly-N-methylglucamide, and octyl α-D-glucopyranoside, dodecyl β. Solubility at room temperature is extremely low, such as -D-cellobioside and N-octylgluconamide.

현재까지 여러 가지 용도를 목적으로 새로운 당계 계면활성제가 개발되고 있지만, 그 용해성은 실용목표를 충족시키지 못하는 경우가 많다. 기존에 탈지 세정을 목적으로 알킬 글루코사이드계 비이온 계면활성제를 사용하는 경우 이들 계면활성제가 강한 수소결합에 의해 결정 안정성을 가지므로 수용액 중에 용해되는 시간이 길어진다는 단점을 보완하기는 어렵다. 따라서, 본 발명에서는 이러한 문제점에 착안하여 소수기로 직쇄 알킬기(alkyl) 사슬을 사용하지 않는 가지형(branched-type) 골격을 가진 이소프렌 글리세라이드를 사용하였다.To date, new sugar-based surfactants have been developed for various purposes, but their solubility often fails to meet practical goals. When the alkyl glucoside-based nonionic surfactant is conventionally used for degreasing cleaning, it is difficult to compensate for the disadvantage that these surfactants have crystal stability due to strong hydrogen bonding, so that the dissolution time in the aqueous solution increases. Therefore, in view of the above problem, the present invention used isoprene glyceride having a branched-type skeleton that does not use a straight chain alkyl chain as a hydrophobic group.

또한, 당을 친수기로 하는 계면활성제와 이온성 계면활성제와의 혼합계는 미셀 형성 및 계면활성을 현저히 상승시킬 수 있는 상승 효과를 가진다는 점에 착안하여 알킬 글루코사이드계, 이소프렌 글리세라이드, 및 N-알칸오일-N-알칸글루코사 미드(MEGA-n, n=8,9,10) 중 한 종의 계면활성제를 선택하여 알킬 황산나트륨(sodium alkyl sulfate)과 혼합하여 상안정성과 세정효과를 극대화시킬 수 있었다. 이때 알킬 황산나트륨(sodium alkyl sulfate)과 혼합한 계면활성제는 소수성 흡착물질에 대해 바람직한 세정효과를 나타낸다.In addition, the alkyl glucoside, isoprene glyceride, and N- are considered to have a synergistic effect that the mixed system of a saccharide-based surfactant with an ionic surfactant can significantly increase micelle formation and surfactant activity. One of the surfactants of alkanoyl-N-alkanoglucosamide (MEGA-n, n = 8,9,10) can be selected and mixed with sodium alkyl sulfate to maximize phase stability and cleaning effect. there was. At this time, the surfactant mixed with sodium alkyl sulfate (sodium alkyl sulfate) shows a desirable cleaning effect for the hydrophobic adsorbent.

알킬 글루코사이드에 알킬 사슬과 유사한 탄소수를 포함하는 알킬 알코올류를 공존용매(cosolvent)로 첨가함으로써 천연 오일, 왁스류 등의 세정효과를 더욱 개선할 수 있다. 이는 첨가한 공존용매에 의해 제거하고자 하는 소수성 오일, 왁스류 등이 보다 친수성화됨으로써 인해 나타난 현상이다. 또한, 상대적으로 공존용매의 첨가는 알킬 글루코사이드와 소수성 물질(오일, 왁스류 등) 간의 혼합계에 보다 효과적인 소수성을 부여함으로써 이러한 소수성 물질에 대한 세정력을 향상시킬 수 있다.By adding an alkyl alcohol having a carbon number similar to the alkyl chain to the alkyl glucoside as a cosolvent, the cleaning effect of natural oils and waxes can be further improved. This phenomenon is caused by hydrophilization of hydrophobic oils and waxes to be removed by the added co-solvent. In addition, the addition of the co-solvent can improve the cleaning power for such hydrophobic substances by giving more effective hydrophobicity to the mixing system between the alkyl glucoside and the hydrophobic substances (oils, waxes, etc.).

본 발명에서는 알킬 알코올류를 첨가하여 O/W형의 에멀젼을 W/O형으로 전환함으로써 소수성 물질에 대한 세정력을 개량하였다. 부가적인 효과로서 알킬 알코올은 조성물 중에서 계면활성제에 의한 기포 발생을 억제할 수 있는 소포제(antifoaming agent) 역할을 할 수 있다. In the present invention, the cleaning power for hydrophobic substances was improved by converting the O / W type emulsion into the W / O type by adding alkyl alcohols. As an additional effect, the alkyl alcohol may serve as an antifoaming agent that can suppress bubble generation by the surfactant in the composition.

본 발명인 목재 절삭용 수계 세정제는 금속부식 방지제를 포함할 수 있다. 그 성분은 규산나트륨(sodium silicate), 4차 탄산암모늄(quaternary ammonium carbonate), 4차 중탄산암모늄(quaternary ammonium bicarbonate), 몰포린(morpholine), 피리디늄(pyridinium), 퀴놀리늄(quinolinium), 4차 알킬탄산암모늄(quaternary ammonium alkylcarbonate), 4차 벤질탄산암모늄(quaternary ammonium benzylcarbonate) 및 이들의 유도체 중에서 선택된 하나 이상을 포함한다.The water-based cleaning agent for cutting wood of the present invention may include a metal corrosion inhibitor. Its components are sodium silicate, quaternary ammonium carbonate, quaternary ammonium bicarbonate, morpholine, pyridinium, quinolinium, 4 Quaternary ammonium alkylcarbonate, quaternary ammonium benzylcarbonate, and derivatives thereof.

또한, 본 발명의 다른 일구현예에 따르면, 알킬 글루코사이드와 알킬 알코올 혼합물의 소수기와 유사한 탄소수를 포함하는 알칸을 추가로 첨가할 수 있다. 알칸을 추가로 포함시킴으로써 혼합 세정제는 소수성 물질에 대해 매우 우수한 세정력을 나타낼 수 있다. In addition, according to another embodiment of the present invention, an alkane containing a carbon number similar to the hydrophobic group of the alkyl glucoside and the alkyl alcohol mixture may be further added. By further including alkanes, the mixed detergent may exhibit very good detergency for hydrophobic materials.

본 발명인 목재 절삭용 수계 세정제는 목재 수지 성분인 레진산 제거를 주요 목적으로 함으로써 조성물의 주성분은 알칼리이고, 기타 조성물은 지방족 알코올류(fatty alcohols), 지방족 산류(fatty acids), 왁스류(waxes), 스테롤류 (sterols), 트리글리세라이드류(triglycerides) 등의 소수성 성분 제거 및 세정 효율성을 높이기 위해 첨가된 것이다.
