AUTOCLAVED LIGHTWEIGHT CONCRETE ADHESIVE COMPOSITION, AND AUTOCLAVED LIGHTWEIGHT CONCRETE ADHESIVE COMPRISING SAME
The present invention relates to an autoclaved lightweight concrete (ALC) adhesive composition and an ALC adhesive comprising the same, the ALC adhesive composition comprising: a dry mixture comprising an inorganic binder and an aggregate; and a hydroxyalkyl alkyl cellulose having an alkyl group degree of substitution (DS) of 1.0-1.8 and having a hydroxyalkyl group degree of molar substitution (MS) of 0.2-1.2, wherein the 2 wt% aqueous solution viscosity of the hydroxyalkyl alkyl cellulose is 10,000-100,000 cps when measured by a Brookfield viscometer in a condition of 20°C and 20 rpm. According to the present invention, the ALC adhesive composition comprises a hydroxyalkyl alkyl cellulose having a suitable viscosity and degree of substitution, thereby enabling an ALC adhesive, which has high water retention capacity and high adhesive strength and is applicable to ALC having a high porosity, to be provided.
La présente invention concerne une composition adhésive pour béton léger autoclavé (ALC) et un adhésif pour ALC la comprenant, la composition adhésive pour ALC comprenant : un mélange sec comprenant un liant inorganique et un agrégat ; et une hydroxyalkyl-alkylcellulose ayant un degré de substitution (DS) de groupe alkyle de 1,0 à 1,8 et un degré de substitution molaire (MS) de groupe hydroxyalkyle de 0,2 à 1,2, où la viscosité en solution aqueuse à 2 % en poids de l'hydroxyalkyl-alkylcellulose, mesurée par un viscosimètre Brookfield dans une condition de 20 °C et 20 tours/minute, est de 10 000 à 100 000 cps. Selon la présente invention, la composition adhésive pour ALC comprend une hydroxyalkyl-alkylcellulose ayant une viscosité et un degré de substitution appropriés, permettant ainsi d'obtenir un adhésif pour ALC, qui a une capacité de rétention d'eau élevée et une force d'adhérence élevée et se prête à une application à un ALC de porosité élevée.
본 발명은 무기계 결합재와 골재를 포함하는 건식혼합물; 및 알킬기 치환도(DS)가 1.0 ~ 1.8이고 히드록시 알킬기 치환도(MS)가 0.2 ~ 1.2인 히드록시알킬 알킬 셀룰로오스;를 포함하고, 상기 히드록시알킬 알킬 셀룰로오스의 2중량% 수용액 점도는 브룩필드 점도계로 20℃ 및 20rpm의 조건에서 측정할 때 10,000 ~ 100,000cps인 것을 특징으로 하는 경량 기포 콘크리트용 접착제 조성물 및 이를 포함하는 경량 기포 콘크리트용 접착제에 관한 것이다. 본 발명에 따른 ALC용 접착제 조성물은, 적절한 점도 및 치환도를 갖는 히드록시알킬 알킬 셀룰로오스를 포함함으로써 높은 기공도를 갖는 ALC에 적용 가능한 고보수성 및 고 접착강도의 ALC용 접착제를 제공할 수 있다.
