일반적으로 무기 조성물은 안료분산제, 소포제, 알루미늄실리케이트나 탄산칼슘 등을 고속분산기로 분산시키고 여기에 스티렌아크릴에멀젼 및 암모니아수 등을 넝ㅎ어서 제조하게 되는데 이 자체로 내오염성, 황변성, 내구성, 항균성, 통기성 등에서 결함을 나타내고 있다. 또한 부분적으로 기능성 물질을 투입하여 기능성을 부여하였으나 이 역시 분산성이 현격히 저하되어 기능성을 주지 못하는 실정이다. 또한 이러한 방법은 기능성 부여 특성별로 기능성 첨가제를 각각 첨가하게 되어 생산성 및 제조원가 상승의 커다란 문제점을 안고있다.In general, the inorganic composition is prepared by dispersing a pigment dispersant, an antifoaming agent, aluminum silicate or calcium carbonate with a high-speed disperser, and styrene acryl emulsion and ammonia water, which are produced by themselves. The defect is shown in air permeability. In addition, the functional material is partially added to give functionality, but this situation is also a situation that does not give the functionality significantly reduced dispersibility. In addition, such a method adds functional additives for each functional granting characteristic, which poses a significant problem of productivity and manufacturing cost increase.

이에 본 발명자들은 통상의 무기 조성물에 함유되어서는 상기한 바와 같은 종래 기술에서 예시된 문제 발생없이 요구되는 기능성 부여가 가능한 기능성 무기 미립자를 별도로 제조하여 함유함으로써 본 발명을 완성하게 되었다.Accordingly, the present inventors have completed the present invention by separately preparing and containing functional inorganic fine particles capable of imparting the required functionality without the problems exemplified in the prior art as described above.

따라서, 본 발명은 통상의 무기 조성물의 기능성 부가를 위해 첨가되는 기능성 무기첨가제를 일정량의 무기충전제, 비이온계면활성제, 알칼리금속염 및 암모늄염과 유화중합하여 무기 미립자로 제조하여 함유시킴으로써 무기 조성물 본연의 물성 변화없이 기능성을 부여하게 되는 다기능성 무기 조성물의 제조방법을 제공하는데 그 목적이 있다.Therefore, the present invention is prepared by emulsifying and polymerizing functional inorganic additives added for the functional addition of conventional inorganic compositions with inorganic fillers, nonionic surfactants, alkali metal salts, and ammonium salts to produce inorganic fine particles, thereby intrinsic physical properties of the inorganic compositions. It is an object of the present invention to provide a method for preparing a multifunctional inorganic composition that provides functionality without change.

본 발명은 포타슘실리케이트, 맥섬석, 아크릴 에멀젼, 분산제가 포함된 통상의 무기 조성물에 기능성 첨가제를 함유시켜 기능성 무기 조성물을 제조하는 방법에 있어서, 상기 기능성 첨가제 유효량과, 무기충전제 50 ∼ 90 중량%, 비이온계면활성제 0.01 ∼ 2 중량%, 알칼리금속염 0.01 ∼ 1 중량% 및 암모늄염 1 ∼ 50 중량%를 유화중합하여 무기 미립자로 제조하여 기능성 첨가제로서 함유하는 다기능성 무기 조성물의 제조방법을 그 특징으로 한다.The present invention is a method for preparing a functional inorganic composition by containing a functional additive in a conventional inorganic composition containing potassium silicate, macsumite, acrylic emulsion, dispersant, the effective amount of the functional additive, 50 to 90% by weight, inorganic filler A method for producing a multifunctional inorganic composition comprising 0.01 to 2% by weight of an ionic surfactant, 0.01 to 1% by weight of an alkali metal salt, and 1 to 50% by weight of an ammonium salt, which are prepared as inorganic fine particles and contained as a functional additive.

이와 같은 본 발명을 더욱 상세히 설명하면 다음과 같다.Referring to the present invention in more detail as follows.

본 발명은 통상의 무기 조성물에 기능성을 부여하기 위해 기능성 첨가제를 첨가함에 있어, 기능성 첨가제를 타소재와의 유화중합하여 무기 미립자로 제조하여 함유시킴으로써 요구되는 기능성을 효과적으로 부여하게 되는 다기능성 무기 조성물의 제조방법에 관한 것이다.The present invention provides a multifunctional inorganic composition that effectively imparts the functionality required by adding a functional additive in order to impart functionality to a conventional inorganic composition, by producing the inorganic fine particles by emulsion polymerization with other materials. It relates to a manufacturing method.

본 발명에서의 무기 조성물은 포타시움실리케이트 10 ∼ 40(SiO2함량) 중량%, 맥섬석 분말 5 ∼ 30 중량%, 분산제 0.1 ∼ 0.5 중량%, 아크릴 에멀젼 1 ∼ 5중량% 및 기타 첨가제 등을 혼합하고 고속교반기로 분산시켜 얻은 균일한 용액 조성물이다. 일반적으로, 상기한 무기 조성물은 농수산물, 식품건조, 자동차 가전제품의 도장건조, 회로판건조, 인쇄잉크건조, 염색건도, 시멘트구조물, 페인트 등의 재료로서 사용되어 왔다.The inorganic composition of the present invention is a mixture of 10 to 40% by weight of potassium silicate (SiO 2 content), 5 to 30% by weight of pulsar powder, 0.1 to 0.5% by weight of dispersant, 1 to 5% by weight of acrylic emulsion, and other additives It is a uniform solution composition obtained by dispersing with a stirrer. In general, the inorganic composition has been used as a material for agricultural and marine products, food drying, coating drying of automobile home appliances, circuit board drying, printing ink drying, dyeing drying, cement structure, paint, and the like.

상기한 무기 조성물에 기능성 부가를 위해 첨가될 수 있는 기능성 첨가제의 종류 및 함량은 극히 제한적으로서 극소량 한도내에서 사용될 수 밖에 없었다. 그러나, 본 발명의 제조방법에 의하면 비교적 과량(대략 1 ∼ 10 중량%)의 기능성 무기 첨가제가 함유가 가능한 바, 이는 기능성 무기 첨가제가 효과적으로 기능성을 발휘할 수 있도록 특정 성분과 함께 유화중합하여 미립자로 제조하여 함유시키므로써 가능해진 것이다.The type and content of the functional additives that can be added for the functional addition to the inorganic composition described above are very limited and can only be used within the minimum amount. However, according to the manufacturing method of the present invention, a relatively excessive amount (about 1 to 10% by weight) of the functional inorganic additive may be contained, which is prepared by the emulsion polymerization with a specific component to produce the fine particles so that the functional inorganic additive can effectively exhibit functionality. It is made possible by containing.

본 발명에 따른 기능성 무기 미립자는, 유기용매에서 기능성 무기첨가제, 무기충전제, 비이온계면활성제, 알칼리금속염 및 암모늄염을 혼합 및 유화중합하여 무기 미립자로 제조한다.The functional inorganic fine particles according to the present invention are prepared as inorganic fine particles by mixing and emulsion polymerizing a functional inorganic additive, an inorganic filler, a nonionic surfactant, an alkali metal salt and an ammonium salt in an organic solvent.

본 발명이 기능성을 부여할 목적으로 사용하는 기능성 무기 첨가제는 당분야에서 기능성을 인정받은 공지의 무기물로서, 예컨대, 은(Ag), 구리(Cu) 함유물을 항균성 무기물로서 첨가할 수도 있다. 상기한 기능성 무기물의 첨가량은 유효활성을 나타낼 수 있는 충분한 양 범위내에서 사용될 수 있다.The functional inorganic additive used for the purpose of imparting functionality to the present invention is a known inorganic substance that has been recognized as functional in the art, for example, silver (Ag) and copper (Cu) content may be added as an antimicrobial inorganic substance. The addition amount of the functional inorganic substance described above may be used within a sufficient amount to exhibit effective activity.

무기충전제는 통상의 것으로서, 소디움실리케이트, 포타시움실리케이트, 소디움 및 포타시움계의 콜로이달실리카, 수산화알루미늄, 점토, 황산바륨, 석분, 탄산칼슘, 티타늄옥사이드, 카오린, 벤토나이트 및 제올라이트 중에서 1종 또는 2종 이상을 선택 사용한다. 무기충전제는 기능성 무기 미립자를 구성하는 전체 조성에 대하여 50 ∼ 90 중량% 범위로 사용하는 바, 그 사용량이 50 중량% 미만이면 -무기조성물을 형성하지 못하고, 90 중량%를 초과하면 과다한 점도 상승으로 인한 입자간의 결합력이 심하여 분산성이 저해되어 사용에 불편함을 초래한다.Inorganic fillers are conventional and include one or two or more of sodium silicate, potassium silicate, sodium and potassium colloidal silica, aluminum hydroxide, clay, barium sulfate, stone powder, calcium carbonate, titanium oxide, kaolin, bentonite and zeolite. Use to select. The inorganic filler is used in the range of 50 to 90% by weight based on the total composition of the functional inorganic fine particles. If the amount of the inorganic filler is less than 50% by weight, it does not form an inorganic composition. Due to the strong bonding force between the particles, dispersibility is inhibited, causing inconvenience to use.

비이온계면활성제는 통상의 것으로서, 구체적으로는 라우릴디메틸아민옥사이드, 코카미도프로필디메틸아민옥사이드 등의 아민옥사이드류, 에틸렌글리콜스테아레이트, 세틸옥타노에이트, 이소옥틸스테아레이트 등의 알킬에스테르류, 폴리옥시에틸렌소비탄모노라우레이트, 폴리옥시에틸렌소비탄모노스테아레이트, 폴리옥시에틸렌소비탄트리올레이트, 포리옥시에틸렌소비탄모노올레이트 등의 폴리소베이트류등이 포함될 수 있다. 상기한 비이온계면활성제는 1종 또는 2종 이상을 혼합 사용할 수 있다. 비이온계면활성제는 기능성 무기 미립자를 구성하는 전체 조성에 대하여 0.01 ∼ 2 중량% 범위로 사용하는 바, 그 사용량이 0.01 중량% 미만이면 무기입자 표면에 효과적인 유화상태를 이루기가 어렵고, 2 중량%를 초과하면 미립자의 크기 조절이 어렵고 또한 잔류 유화제의 회수 및 과다한 원가 상승의 문제가 된다.Nonionic surfactants are conventional ones, specifically, amine oxides such as lauryldimethylamine oxide and cocamidopropyldimethylamine oxide, alkyl esters such as ethylene glycol stearate, cetyloctanoate, isooctyl stearate, Polysorbates such as polyoxyethylene sorbitan monolaurate, polyoxyethylene sorbitan monostearate, polyoxyethylene sorbitan trioleate, and polyoxyethylene sorbitan monooleate. Said nonionic surfactant can be used 1 type or in mixture of 2 or more types. The nonionic surfactant is used in the range of 0.01 to 2% by weight based on the total composition of the functional inorganic fine particles. When the amount is less than 0.01% by weight, it is difficult to form an effective emulsified state on the surface of the inorganic particles, and 2% by weight is used. If exceeded, it is difficult to control the size of the fine particles, and the problem of recovery of residual emulsifier and excessive cost increase.

알칼리금속염으로는 바람직하기로는 알카리금속의 과염소산염을 사용하는 것이며, 예를 들면 리튬퍼클로로레이트, 소디움퍼클로로레이트, 포타시움퍼클로로레이트를 선택 사용할 수 있다. 알칼리금속염은 기능성 무기 미립자를 구성하는 전체 조성에 대하여 0.01 ∼ 1 중량% 범위로 사용하는 바, 그 사용량이 0.01 중량% 미만이면 낮은 전도도가 형성되고, 1 중량%를 초과하면 자체응집 및 전도도를 증가하는데 더 이상의 효과가 없다.As the alkali metal salt, an alkali metal perchlorate is preferably used. For example, lithium perchloroate, sodium perchlororate, or potassium perchlorate can be selected and used. Alkali metal salt is used in the range of 0.01 to 1% by weight based on the total composition of the functional inorganic fine particles. If the amount is less than 0.01% by weight, low conductivity is formed, and when it exceeds 1% by weight, self-aggregation and conductivity are increased. There is no more effect.

암모늄염으로는 암모늄카보네이트, 암모늄비카보네이트, 암모늄비플로라이드, 암모늄비설페이트, 암모늄세릭나이트레이트, 암모늄락테이트 중에서 1종 또는 2종 이상을 선택 사용한다. 암모늄염은 기능성 무기 미립자를 구성하는 전체 조성에 대하여 1 ∼ 50 중량% 범위로 사용하는 바, 그 사용량이 1 중량% 미만이면 효과적인 미립자의 크기조절이 어렵고, 50 중량%를 초과하면 잔류 암모늄의 회수 및 과다한 원가 상승의 문제가 된다.As the ammonium salt, one or two or more selected from ammonium carbonate, ammonium bicarbonate, ammonium bifluoride, ammonium bisulfate, ammonium ceric nitrate, and ammonium lactate are used. The ammonium salt is used in the range of 1 to 50% by weight based on the total composition of the functional inorganic fine particles. When the amount is less than 1% by weight, it is difficult to effectively control the size of the fine particles. This is a problem of excessive cost increase.

그리고, 상기한 조성성분을 혼합하고 유화중합하는 용매로서 물 및 메탄올, 에탄올, 이소프로판올, 2-에톡시에탄올 등이 사용될 수 있으며, 상기 용매는 1종 또는 2종 이상을 사용할 수 있다.In addition, water and methanol, ethanol, isopropanol, 2-ethoxyethanol, and the like may be used as a solvent for mixing and emulsion-polymerizing the above-mentioned components, and the solvent may be used alone or in combination of two or more thereof.

이상의 조성성분들을 혼합 및 유화중합하며, 중합이 완료되면 염산, 황산 질산의 묽은 산 용액으로 세척하여 미반응 물질과 불순물을 제거하고 다시 물로 세척하고 건조하여 기능성이 부여된 무기 미립자를 얻는다. 제조된 무기 미립자는0.05 ∼ 100 ㎛의 균일한 입자크기를 갖는다.The above components are mixed and emulsion-polymerized, and when the polymerization is completed, washed with a dilute acid solution of hydrochloric acid and sulfuric acid nitric acid to remove unreacted substances and impurities, followed by washing with water and drying to obtain inorganic fine particles imparted with functionality. The prepared inorganic fine particles have a uniform particle size of 0.05 to 100 μm.

이상의 제조방법으로 제조된 기능성 무기 미립자는 균일한 크기를 가지고 있고, 다기능성을 부여하고 있어 여러 목적의 재료로서 간편하게 공정에 이용될 수 있다.The functional inorganic fine particles produced by the above manufacturing method have a uniform size, impart versatility, and can be conveniently used in the process as materials for various purposes.
