현대사회를 사는 우리로서는 주거환경의 변화로 인하여 건축자재 및 시공상의 이익 극대화를 목적으로 피해가 고스란히 소비자에게 전달되어 주거환경으로 인한 소비자들의 삶이 위협받고 있는 상황이다. As a living in the modern society, the damage has been transmitted to the consumers for the purpose of maximizing the profit of the building material and the construction due to the change of the residential environment, and the life of the consumers due to the residential environment is threatened.
특히 주거용 건축물의 마감재인 도료나 접착제 등은 제조과정뿐만 아니라 시공 중에도 발암 물질과 같은 인체에 해로운 물질을 발생함은 물론 시공 후에도 상당기간 잔존하여 지속적으로 배출함으로 인하여 아토피나 천식 등의 여러 가지 질병의 원인으로 인식되고 있으며, 특히 신축건축물에서는 호흡기 장애, 알레르기, 두통, 신경계 이상, 구토, 현기증, 시력 저하 등을 유발하는 새집 증후군 증후군의 사례가 빈번히 발생하고 있다.In particular, paints and adhesives, which are the finishing materials for residential buildings, cause not only the manufacturing process but also harmful substances such as carcinogenic substances during construction, as well as the persistent release after a long period of time. In particular, new housing syndromes that cause respiratory disorders, allergies, headaches, nervous system abnormalities, vomiting, dizziness, and poor visual acuity are frequently encountered in new buildings.
더 나아가서는 화재 발생시 휘발성 유기화합물(VOC)로 인하여 심각한 유독 가스가 발생할 뿐만 아니라 연소성이 용이하므로 수많은 인명피해 및 막대한 재산피해가 발생하고 있다.Furthermore, when a fire occurs, a toxic gas is generated due to volatile organic compounds (VOC), and since it is easy to combust, numerous human lives and enormous property damage are occurring.
특히 종래에는 폴리우레탄 수지를 유기용매 중에서 합성하여 사용하였는바, 이러한 경우, 제조 및 경화과정 중 유기용매가 대기 중으로 증발되어 용매의 손실에 의한 경제적 손실뿐만 아니라, 대기 오염물질의 발생으로 환경오염을 야기하였으며, 이러한 오염물질은 공기 중 다른 기체와 반응하여 제3의 오염물질을 생성시키는 문제점이 있을 뿐만 아니라 인화성과 연소성이 높은 휘발성 유기화합물을 포함하고 있다.In particular, in the past, a polyurethane resin was synthesized in an organic solvent. In such a case, the organic solvent evaporated into the atmosphere during the production and curing process, resulting in an economic loss due to the loss of the solvent, These pollutants not only have a problem of reacting with other gases in the air to generate third pollutants, but also contain volatile organic compounds having high flammability and high combustion.

또한, 본 발명의 실시예에 따른 친환경 무기질 난연성 접착제 조성물의 제조방법은 제1용액 준비단계와, 제2용액 준비단계와, 제1,2용액 혼합 및 교반단계와, 제3용액 준비단계 및 접착제 제조단계로 구성된다.The method for producing an environmentally friendly inorganic flame-retardant adhesive composition according to an embodiment of the present invention may further include a first solution preparing step, a second solution preparing step, a first solution mixing and stirring step, a third solution preparing step, And a manufacturing step.
상기 제1용액 준비단계는 물 35중량%에 폴리비닐알코올(Polyvinyl alcohol, PVA) 5중량%를 넣어 교반 하고, 교반 중에 염화마그네슘(MgCl2)을 첨가하여 교반함으로써 염화마그네슘이 분산된 용액을 준비하는 단계이다.In the first solution preparation step, 5% by weight of polyvinyl alcohol (PVA) is added to 35% by weight of water, stirring is performed, and magnesium chloride (MgCl 2 ) is added during stirring to prepare a solution in which magnesium chloride is dispersed .
상기 제2용액 준비단계는 물 5중량%에 활석(Talc) 16중량%와 덱스트린(Dextrin) 2중량%, 폴리아크릴아마이드(Polyacrylamide, PAM) 2중량% 및 아세트산(CH3COOH) 1중량%를 넣어 교반하면서 녹여 준비하는 단계이다.The second solution preparation step may be performed by adding 16 wt% of talc, 2 wt% of dextrin, 2 wt% of polyacrylamide (PAM) and 1 wt% of acetic acid (CH 3 COOH) Followed by melting and preparing the mixture while stirring.
또한 상기 제1,2용액 혼합 및 교반단계는 상기 제1용액 준비단계를 통해 준비된 제1용액과 제2용액 준비단계를 통해 준비된 제2용액을 혼합한 후 교반하는 단계를 거치게 된다.The mixing and stirring of the first and second solutions may be performed by mixing the first solution prepared through the first solution preparing step and the second solution prepared through the second solution preparing step.
상기 제1,2용액 혼합 및 교반단계를 수행한 다음에는 물 5중량%에 아교 8중량%를 넣어 충분히 교반하고, 교반 중에 카세인(Casein) 2중량%를 첨가하여 계속 교반하여 졸(sol) 상태의 아교 및 카세인 혼합용액을 준비하는 제3용액 준비단계를 거치게 되며, 상기 제1,2 혼합용액과 제3용액을 혼합하고 교반하면서 교반 중에 테레빈유(Turpentine) 1중량%를 첨가하여 교반하고 다시 교반 중에 카복시메틸셀룰로스(Carboxymethyl cellulose, CMC) 2중량%를 첨가하고 교반하는 접착제 제조단계를 통해 접착제를 완성하게 된다.After the first and second solutions were mixed and stirred, 8 wt% of glue was added to 5 wt% of water and sufficiently stirred. 2 wt% casein was added to the solution while stirring, The first and second solutions are mixed and stirred. While stirring, 1% by weight of Turpentine is added to the solution, and the mixture is stirred again. During the stirring, 2% by weight of carboxymethyl cellulose (CMC) is added and the adhesive is finished through the stirring step of producing the adhesive.
보다 상세히 설명하면, 상기 제1용액 준비단계에서는 약 70~80℃로 가열된 물 35중량%에 폴리비닐알코올(Polyvinyl alcohol, PVA) 5중량%를 넣고 교반하면서 염화마그네슘(MgCl2) 16중량%를 첨가하여 약 30~40분간 교반하여 완전히 분산되도록 한다. More specifically, in the first solution preparing step, 5% by weight of polyvinyl alcohol (PVA) is added to 35% by weight of water heated to about 70 to 80 ° C. and 16% by weight of magnesium chloride (MgCl 2 ) And the mixture is stirred for about 30 to 40 minutes to be completely dispersed.
상기 폴리비닐알코올(PVA)과 후술하는 아교 등은 접착제로서의 효과를 발휘하며, 상기 염화마그네슘(MgCl2)은 염소와 마그네슘의 화합물로서 대기 중에 습기를 빨아들이는 성질이 있어 접착제가 도포되거나 혼합되는 기초 재료의 항습과 방염 특성을 향상시키는 조성물로서 본 발명에 의한 친환경 접착제의 효능을 향상시키는 역할을 수행한다.The polyvinyl alcohol (PVA) and the glue described below exhibit an effect as an adhesive. The magnesium chloride (MgCl 2 ) is a compound of chlorine and magnesium, and has a property of absorbing moisture in the air, The composition improves the moisture-proofing and flame-proofing properties of the base material and improves the efficacy of the environment-friendly adhesive according to the present invention.
상기 제2용액 준비단계에서 활석과 폴리아크릴아마이드(Polyacrylamide, PAM) 및 아세트산(CH3COOH)과 함께 물에 넣어 교반되는 덱스트린(Dextrin)은 물과 혼합되는 과정에서 잘 녹지 않는 상태가 되므로 폴리아크릴아마이드(PAM) 용액을 잘 녹이고 아세트산을 첨가함으로써 분산 혼합을 촉진시킨다. 특히, 활석과 폴리아크릴아마이드 및 덱스트린은 접착제가 도포되거나 혼합되는 분쇠된 목재나 발포된 스티로폼과 같은 기초재료의 탄성을 증가시키고 도포 시나 혼합시의 접착력을 향상시키는 조성물로서 교반시 용액 내에서 골고루 분산되도록 하는 것이 바람직하다.In the second solution preparing step, dextrin stirred with talc and water together with polyacrylamide (PAM) and acetic acid (CH 3 COOH) becomes insoluble in the process of mixing with water, Amide (PAM) solution is dissolved well and acetic acid is added to promote dispersion mixing. Particularly, talc, polyacrylamide and dextrin are compositions which increase the elasticity of basic materials such as crushed wood or foamed styrofoam in which an adhesive is applied or mixed, and improve the adhesive force during application or mixing, .
또한 상기 제3용액 준비단계를 통해 준비되는 졸(sol) 상태의 아교 및 카세인 혼합용액은 상기 제1,2용액 혼합 및 교반단계를 통해 교반 혼합되는 물, 폴리비닐알콜, 염화마그네슘, 활석, 덱스트린, 폴리아크릴아마이드 및 아세트산과 분리하여 혼합하도록 하는 것이 바람직하다. 따라서, 약 70~80℃의 물에 아교를 넣고 약 30~40분 동안 교반하여 아교가 녹은 물이 흐물거릴때 까지 녹여 준비하며, 여기에 카세인(Casein)을 첨가하여 10분 이상 계속 교반함으로써 졸(Sol) 상태의 아교 및 카세인 용액을 따로 준비하고 이 용액에 앞에서 준비된 제1,2 혼합 용액을 섞어 교반하게 된다. 제3용액 준비단계에서 혼합 교반되는 아교(Glue)는 본 발명에 의한 접착제가 혼합되는 분쇄된 목재나 발포된 스티로폼과 같은 기초 재료의 진동이나 내충격성, 압축강도 및 인장강도를 향상시키는 조성물로 작용하게 되며, 상기 카세인(Casein)은 점성과 접착력을 높이는 효과를 발휘한다.Also, the mixed solution of glue and casein in the sol state prepared through the third solution preparing step is mixed with water, polyvinyl alcohol, magnesium chloride, talc, dextrin , Polyacrylamide, and acetic acid. Therefore, glue is added to water at about 70 to 80 ° C and stirred for about 30 to 40 minutes to dissolve the glue-dissolved water until it is disturbed. Casein is added thereto and stirring is continued for 10 minutes or longer, (Sol) state of glue and casein solution are separately prepared, and the first and second mixed solutions prepared above are mixed and stirred. The glue mixed and stirred in the third solution preparation step acts as a composition for improving the vibration, impact resistance, compressive strength and tensile strength of the base material such as pulverized wood or foamed styrofoam to which the adhesive according to the present invention is mixed And the casein exerts an effect of increasing viscosity and adhesion.
또한 상기 제1,2 혼합용액과 제3용액을 혼합하고 교반하면서 교반 중에 첨가되는 테레빈유(Turpentine)는 송진(Pine resin)을 수증기로 증류하는 과정에서 얻어지는 정유로서, 접착제가 도포되거나 혼합되는 기초재료의 방충작용 및 응집력을 향상시키는 데 작용한다.Turpentine, which is added during stirring with mixing of the first and second mixed solution and the third solution, is an essential oil obtained by distilling the pine resin with steam, It works to improve insecticide and cohesion of materials.
이와 같이 본 발명의 실시예에 의한 친환경 난연성 무기질 접착제는 폴리비닐알코올 및 아교 등이 접착제의 성능을 발휘하고, 모든 재료가 무기질로서 친환경적이며, 활석 및 염화마그네슘 등의 재료에 의해 난연성을 발휘할 뿐만 아니라 용매가 물로서 수성 접착제의 성질을 발현하여 인화시 유독성 가스의 배출을 방지한다. As described above, the environmentally flame-retardant inorganic adhesive according to the embodiment of the present invention exhibits the performance of an adhesive such as polyvinyl alcohol and glue, and all the materials are environmentally friendly as an inorganic material and exhibit flame retardancy by a material such as talc and magnesium chloride The solvent manifests the properties of an aqueous adhesive as water to prevent the release of toxic gases during printing.
또한 위에서 서술한 각 성분의 성분함량은 최적의 접착력을 제공할 뿐만 아니라 방염, 방습, 방충, 항습의 특성을 극대화시키는 효과가 있다.In addition, the component content of each component described above not only provides the optimum adhesive force but also has the effect of maximizing the properties of flame retardation, moisture-proof, insecticide and moisture-proof.
