초록

Butylacylate (BA)와 2-Ethylhexylacrylate (2-EHA)를 토대로 하여 수성 아크릴 점착제를 제조함에 있어서 경질성(rigidity)을 부여 하기 위하여 methyl methacrylate (MMA)를 부가 단량체로 사용하였다. 기능성 단량체의 영향을 파악하기 위하여 여러가지 기능성 단량체를 각각 1, 2, 3%를 사용하여 유화 중합(emulsion polymerization)을 하였다. 2-acrylamido-2-methyl-1-propanesulfonate acid를 사용한 아크릴 에멀젼 점착제가 접착물성이 가장 좋았다. Acrylic acid와 dimethyl-2-imidazlidon acrylate를 포함하는 아크릴 에멀젼 점착제는 물성은 좋으나 응집력이 약해 점착력 시험 중에 피착체로의 전이가 일어나는 것을 볼 수 있었다. 2-acrylamido-2-methyl-1-propanesulfonate acid의 함량이 많아질수록 접착력이 좋아졌으나 7 w% 이상에서는 점착력이 저하되는 것을 볼 수가 있었다.

The waterborne acrylic pressure-sensitive adhesive in the basis of butylacylate (BA) and 2-Ethylhexylacrylate (2-EHA) was synthesized and the methyl methacrylate (MMA) have been used to give the rigidity perfroamce. The polymreric latex was synthesized using butyl acrylate (BA), 2-ethylhexyl acrylate (EHA), methyl methacrylate (MMA) and each 1, 2, 3% of various functional monomers. The dimethyl-2-imidazlidon acrylate and 2-acrylamido-2-methyl-1-propanesulfonate was used in order to increase the wetting properties of acrylic emulsion. To study of properties of functional monomer, The polymreric latex was synthesized various functional monomers each 1, 2, 3%. The 2-acrylamido-2-methyl-1-propanesulfonate showed the best properties. Latex with acrylic acid and dimethyl-2-imidazlidon acrylate had good peel strength, holding power, but it showed that they didn't separate from adhered cleanly by weak cohesion strength. The adhesion performance was increased by increasing amount of 2-acrylamido-2-methyl-1-propanesulfonate however latexes with upper 7% 2-acrylamido-2-methyl-1-propanesulfonate showed that the properties of PSA decreased.
