Abstract

The bubble hardened article (4) is manufactured by mixing a polyvinyl alcohol (PVA) of a water soluble synthetic resin as a bubble generating agent with water to form bubbles (1,1') and a soft diaphragm (2), and adding a borax and a sodium silicate as a quick setting agent and a high early strengthening agent to the formed diaphragm (2) to form a hard diaphragm (3). The bubble hardened article is used as a raw material for producing PC panels, sandwich panels, bricks, blocks and heat insulating materials.

본 발명은 기포경화체에 관한 것으로, 더 상세하게는 기포발생체로서 수용성 합성수지인 PVA에 물을 가해 기포를 조성한후 급결 조강제로서 붕사 및 규산소다를 첨가하여 기포는 그대로 유지된체 기포막이 경화된 기포경화체를 제조함으로서 경량인 PC판넬, 샌드위치판넬, 벽돌, 블록, 단열재등의 토목 건축자재를 생산하는 원료로 사용되게 한 것이다.The present invention relates to a bubble hardening body, and more specifically, bubbles are formed by adding water to PVA, a water-soluble synthetic resin, as a bubble generator, and then adding borax and sodium silicate as a quickening adjuvant to cure a bubble film in which a bubble is maintained as it is. By manufacturing a bubble hardening body, it is used as a raw material for producing civil construction materials such as lightweight PC panels, sandwich panels, bricks, blocks, and insulation materials.

최근 각종 화공약품에 의한 조제로서 경량 콘크리트를 제조하고 있으나 많은 화공약품의 사용에 의한 제조단가가 고등하여 대중화시킬 수 없고, 화공약품에 의한 이상 반응으로 그 강도가 저하되어 실용성이 없다.Recently, lightweight concrete is manufactured as a preparation by various chemicals, but the production cost is high due to the use of many chemicals, and it cannot be popularized.

더욱이 최근 합성수지 발포제로서 고안된 제품은 대부분 인화성 물질일뿐 아니라 화재시 유독가스가 발생하여 인명피해를 초래하는 문제점이 있는 것이다.In addition, the products designed as a synthetic resin blowing agent in recent years is not only a flammable material, but also has a problem of causing toxic gases in the event of fire, resulting in human injury.

본 발명은 기포발생제로서 발생시킨 기포의 격막을 급결제와 조강제인 붕사 및 규산소다로서 경화시킨 기포경화체를 제조하여 각종 무기물을 배합 성형하는 토건자재의 원료로 사용되게한 것이다. 이하 발명의 요지를 그 실시예에 의하여 상세히 설명하면 다음과 같다. 기포발생제로서 수용성 합성수지인 PVA에 물을 3 : 1의 비율로 섞어서 통상의 방법으로 제1도(a)와 같이 기포(1)(1') 및 연질격막(2)이 형성되게 된다. 이때 급결재 및 조강제로서 붕사 및 규산소다를 중량비로 약 3% 가량 첨가 혼합하면 중성인 연질격막(2)이 강알카리인 급결제 및 조강제와 반응하여 순간적으로 경질격막(3)으로 변화됨으로서 기포(1)(1')가 그대로 유지된 기포경화체(4)가 제조되는 것이다.The present invention is to prepare a bubble cured body of the foamed diaphragm generated as a foaming agent with a fastener and borax and sodium silicate to be used as a raw material for construction materials for mixing and molding various inorganic materials. Hereinafter, the gist of the invention will be described in detail by way of examples. As the bubble generator, water is mixed with PVA, which is a water-soluble synthetic resin, in a ratio of 3: 1, thereby forming bubbles (1) (1 ') and the soft diaphragm (2) as shown in FIG. At this time, when about 3% of borax and sodium silicate are added and mixed as a quickener and a coarse additive, the neutral soft diaphragm 2 reacts with the strong alkaline quickener and the coarse agent to instantly change into a hard diaphragm 3. The bubble hardening body 4 in which the bubble (1) (1 ') was maintained as it is is manufactured.

이와같이된 본 발명의 기포경화체는 무기질인 시멘트, 돌가루와, 세골재에 통상의 방법으로 혼합 임의의 규격 또는 방법으로 성형 양생하게되면 기포성 경량 PC 판넬이나 샌드위치판넬, 블록, 벽돌, 단열재 기타각층 토목 건축자재를 제조할 수 있는 것이다.Thus, the foam hardener of the present invention is mixed with inorganic cement, stone powder, and fine aggregates in the usual way, and molded and cured in any standard or method, foaming lightweight PC panels or sandwich panels, blocks, bricks, thermal insulation materials and other various civil constructions. The material can be manufactured.

이와같이된 본 발명의 기포경화체는 내화성이고 극히 경량임으로 특히 겹충하여 제조하는 샌드위치판넬의 제조에 적합하고 그 물성이 단열, 결로방지등 최근 토건자재가 요구하는 특성을 유지할뿐 아니라 화공약품의 사용이 미소하여 무기질과의 양생시 약화반응된 염려가 없으며 가격이 저렴하여 널리 실용화시킬 수 있는 효과가 있는 것이다.Thus, the foam curable body of the present invention is fire-resistant and extremely lightweight, and is particularly suitable for the manufacture of sandwich panels manufactured by overlapping, and its physical properties not only maintain the characteristics required by recent construction materials such as insulation and condensation prevention, but also use of chemicals is very small. There is no fear of weakening reaction when curing with minerals, and the price is cheap and there is an effect that can be widely used.
