Description

폴리비닐알콜을 주제로 한 기포제의 제조방법Manufacturing method of foam agent based on polyvinyl alcohol

본 발명은 다포(多泡) 건축 자재 제조용 폴리비닐알콜을 주제로한 기포제의 제조방법에 관한 것이다.TECHNICAL FIELD This invention relates to the manufacturing method of the foaming agent based on polyvinyl alcohol for the manufacture of many fabric materials.

종래에는 다포 건축자재 제조용 기포제로는 금속분말이나 동물성 유지를 가수 분해한 것이 주로 사용되었으나 이와 같은 기포제를 이용하여 제조한 건축자재는 압축강도가 약할 뿐 아니라, 기포 발생이 충분치 못하고 기포 형성도 균일치 못하므로 단열성, 흡음성이 불량하며, 응결시간이 긴 결점이 있어 실용화하는데는 여러가지 난점이 있었다.Conventionally, as a foaming agent for manufacturing multi-porous building materials, hydrolyzed metal powders or animal fats and oils were mainly used, but building materials manufactured using such foaming agents are not only weak in compressive strength, but also have insufficient foaming and uniform bubble formation. As a result, there is a drawback of poor insulation and sound absorption and a long condensation time.

본 발명 기포제를 이용하여 제조한 건축자재는 종래 기포제를 이용하여 제조한 건축자재와는 달리 기포 형성이 균일할 뿐 아니라, 응결시간이 짧고, 압축 강도가 커서 본 발명 기포제를 시멘트와 혼합하여 주형에 부어 제조한 건축자재를 주택의 벽체, 브럭, 고층아파트의 단열, 흡음재로 사용하면 몰탈이나 스티로폴보다 저렴한 가격으로 시공할 수 있다. 이와 같은 본 발명 기포제의 구체적인 제조방법은 다음과 같다.Unlike the building materials manufactured by using the foaming agent, the building material manufactured by using the foaming agent of the present invention has not only uniform foam formation but also a short condensation time and a high compressive strength, so that the foaming agent of the present invention is mixed with cement to form Poured building materials can be used at a lower price than mortar or styropol if used as insulation and sound absorbing materials for walls, blocks, and high-rise apartments. The specific manufacturing method of such a foaming agent of this invention is as follows.

반응조에 기포제인 폴리비닐 알콜을 넣은 후 탄산수소나트륨과 표면활성제로 라우릴황산나트륨을 넣고 발포제로 프레온-113(Freon-113)을 첨가한 다음 교반하여 유액상태로 분산시킨 후 경화제로 염화칼슘, 암모니아수를 가하고 가열 교반하여 균일 용액으로 한 다음 반응 촉진제로 수산화나트륨을 가하고 인산으로 중화시켜 고형분이 전체 중량의 50%가 되도록 농축하여 제조한다.Add polyvinyl alcohol as a foaming agent to the reactor, add sodium carbonate and sodium lauryl sulfate as a surfactant, add Freon-113 as a blowing agent, disperse it in an emulsion state, and disperse it in an emulsion state. The mixture is heated and stirred to form a homogeneous solution, and then, sodium hydroxide is added as a reaction accelerator, and neutralized with phosphoric acid, whereby the solid is concentrated to 50% of the total weight.

상기와 같이 제조한 기포제를 시멘트와 혼합 교반하면 기포제인 폴리비닐알콜이 프레온-113의 발포작용에 의하여 기포 발생이 원활하게 되며 라우릴황산나트륨의 표면활성 작용에 의하여 기포 형성이 균일하게 되고, 염화칼슘, 탄산수소나트륨의 시멘트 조강 작용으로 시멘트의 응결시간이 단축되고, 염화칼슘, 인산나트륨등이 폴리비닐알콜의 응고를 촉진하여 단시간에 목적하는 다포 건축자재를 제조할 수 있을 뿐 아니라, 제조된 제품은 콘크리트 내부에 존재하는 기포의 벽면이 응고 폴리비닐 알콜로되어 있어 콘크리트의 강도를 보강하여 주므로 제품의 압축 강도가 크고 단열성, 흡음성이 큰 특징이 있다.Mixing and stirring the foaming agent prepared as described above, the foaming agent of polyvinyl alcohol, the foaming agent, is smoothly generated by the foaming action of Freon-113, and the foaming is uniformed by the surface active action of sodium lauryl sulfate, and calcium chloride, The cement coagulation time is shortened by the cementing action of sodium bicarbonate, and calcium chloride, sodium phosphate, etc., promote the coagulation of polyvinyl alcohol, so that not only a short time can be manufactured, but also the manufactured products are concrete. The wall surface of the bubbles inside is made of solidified polyvinyl alcohol to reinforce the strength of concrete, so the product has a high compressive strength and high heat insulation and sound absorption.

[실시예]EXAMPLE

교반기와 냉각기가 부착된 반응조에 물500ml에 폴리비닐알콜 200g과 탄산수소나트륨 150g을 넣은 다음 라우릴황산나트륨 5g과 프레온-113 10ml을 넣고 교반하여 유액상으로 분산시킨 후 염화칼슘 80g, 암모니아수(28%) 10g을 첨가하고 70℃ 가 되도록 가열 교반한 다음 가성소오다 20g을 넣고 인산을 주가하면서 냉각하여 중화시킨 후 농축하여 고형분 50%의 최종 생성물을 얻는다.In a reactor equipped with a stirrer and a cooler, 200 g of polyvinyl alcohol and 150 g of sodium hydrogen carbonate were added to 500 ml of water. Then, 5 g of sodium lauryl sulfate and 10 ml of freon-113 were added to the mixture, stirred, and dispersed in an emulsion. 10 g is added, and the mixture is heated and stirred to 70 ° C., 20 g of caustic soda is added thereto, cooled by neutralization with phosphoric acid, and concentrated to obtain a final product having a solid content of 50%.
