초록

고형분 함량이 높고 안정성이 우수한 NBR 라텍스를 얻기 위하여 아크릴계 응집제 라텍스(agglomeration latex)를 합성하였다. 응집제 라텍스는 산성 단량체인 methacrylic acild와 ethylacrylate를 seeded emulsion 중합법으로 합성하였다. 응집제 라텍스의 합성에 있어서 유화제의 양이 감소할수록 그리고 potassium persulfatd 개시제의 양이 증가할수록 입자경은 증가하였으며 KCl, K2CO3와 같은 eletrolyte의 첨가에 의해서도 입자경이 증가하였다. 응집제 라텍스로 응집된 NBR base latex는 bimodal 입자경 분포를 나타내었으며 농축 과정에서도 입자경의 증가가 관찰되었다. 또한 응집제 라텍스를 사용하지 않을 경우, NBR base latex는 고형분을 45 wt%이상 향상시킬 수 없었으나, 아크릴계 응집제 라텍스로 응집된 NBR latex는 고형분 54 wt%까지 안정한 상태를 유지하였다.

In order to increase the solid content of NBR latex while maintaining latex stability, an acrylate type agglomeration lattices were synthesized. Seeded emulsion polymerization was used to get agglomeration latices. As the amount of emulsifier increased and that of potassium persulfate initiator decreased, the particle size of agglomerating latices increased. The addition of electrolytes, such as KCl and K2CO3, also increased the particle size of agglomeration latex. NBR latex after agglomeration process exhibited increased of particle sizes with bimodal distribution. While NBR base latex itself could be concentrated up to 45 wt% solid content, the NBR latex with added agglomeration latex could be concentrated up to 54 wt% without loosing latex stability.
