초록

아크릴 에멀젼 수지에 HW-100, Aerosil, HEMC (hydroxyethyl methylcellulose), HPMC(hydroxypropyl methylcellulose)을 종류별로 혼합하여 물리적 특성을 조사하였다. 아크릴 수지계 증점제인 HW-100 혼합물은 높은 점도와 큰 칙소성을 나타내었으며, 증점제를 증량시킴에 따라 점도는 높은 값을 나타내었고, 칙소성이 클수록 흐름 특성이 나빠 제조작업성은 불량하였다. 미립자 실리카계 증점제인 Aerosil 혼합물은 제조 작업성, 접착력, 내수성등에서 우수하였지만 큰 수축율을 나타내었으며, 수축율에 가장 큰 영향을 미치는 인자는 수분과 기포의 함량이었다. 셀루로오스계 증점제인 HEMC 혼합물은 높은 pH와 부착력을 나타내었으며, HPMC 혼합물은 긴 건조 시간과 우수한 내알칼리성을 나타내었다. 내수성 및 내알칼리성에 영향을 미치는 인자는 수지의 분자 구조 및 기포의 함량 등이었다.

HW-100 (acryl oligomer), Aerosil 200 (fine silica), HEMC (hydroxyethyl methylcellulose) and HPMC (hydroxypropyl methylcellulose) were each mixed with acryl emulsion resin. For each mixture, various physical properties were tested experimentally. Hw-100 mixtures showed higher viscosity and thixotropy than the other mixtures. The viscosity increased rapidly with adding of thickener. Fabrication workability decreased substantially with increased thixotropy. Aerosil mixture represented good properties in workability, adhesive strength and water-resistance, however, it had large shrinkage. The shrinkage was typically influenced by content of water and void. HEMC mixture showed higher pH and adhesion than others, while HPMC mixture had long drying-time and excellent alkali-resistance characteristics. Water-resistance and alkali-resistance were mainly influenced by the molecular structure of thickener and the content of voids.
