Description
본 발명은 아크릴계 에멀젼 점착제에 대한 것으로서 더욱 상세하게는 내열특성 및 점착성이 우수하고 고고형 분화에 의하여 건조시간의 단축이 가능한 아크릴계 에멀젼 점착제에 관한 것이다.The present invention relates to an acrylic emulsion pressure-sensitive adhesive, and more particularly, to an acrylic emulsion pressure-sensitive adhesive which is excellent in heat resistance and adhesiveness and which can shorten the drying time by solidifying differentiation.
지금까지 수분산성 점착제는 점착력이나 내열성 等 성능면에서 유기용제형 점착제에 비하여 저하되므로 점착성이나 내열성이 크게 요구되지 않는 분야에 한정되어 사용되어 왔으나 점착제 산업의 무공해와, 작업 청정화에 대한 요구의 증대에 따라 수분산성 점착제에 대한 요구도 증대되고 있는 실정이다.Until now, water-dispersible pressure-sensitive adhesives are lower than those of organic solvent-type pressure-sensitive adhesives in terms of adhesive strength and heat resistance and performance. However, water-dispersible pressure-sensitive adhesives have been used in areas where adhesiveness and heat resistance are not largely required. Accordingly, there is an increasing demand for water-dispersible pressure-sensitive adhesives.
따라서, 수분산성 점착제는 지금까지 용제형 점착제가 사용되고 있던 고성능, 고기능 점착제 분야로 응용범위를 확장하고 있으나 아직까지 수분산성 점착제가 갖는 내수성, 초기 점착성이 떨어지는 문제, 약한 점착력 등의 문제로 인해 사용량이 한정되고 있으며, 특히 수분산성 아크릴계 에멀젼 점착제를 자동차와 같이 높은 점착력을 요구하면서도 고도의 응집력과 내열성 등 요구물성이 까다로운 분야에 응용하기 위해서는 해결하여야 할 문제가 많은 것으로 알려져 있다.Therefore, the water-dispersible pressure-sensitive adhesive is expanding the application range to the high-performance, high-performance pressure-sensitive adhesive field that has been used solvent-based pressure-sensitive adhesives, but the amount of water-dispersible pressure-sensitive adhesive is still used due to problems such as water resistance, poor initial adhesiveness, weak adhesive strength, etc. In particular, in order to apply a water-dispersible acrylic emulsion pressure-sensitive adhesive in a field where demanding properties such as high cohesion and heat resistance are required while requiring high adhesive strength as in automobiles, there are many problems to be solved.
본 출원인은 상기와 같은 사항을 고려하여 고도의 점착력과 응집력 및 내열성이 요구되는 분야에 사용될 수 있는 아크릴계 에멀젼 점착제를 개발하기 위하여 예의 연구 검토한 결과 건조시간이 짧고 낮은 유리전이 온도를 가지면서도 고도의 응집력과 내열성을 발휘하는 아크릴계 에멀젼 점착제를 개발하고 본 발명을 완성하였다.In light of the above, the present inventors have conducted extensive studies to develop an acrylic emulsion adhesive that can be used in a field requiring high adhesion, cohesion and heat resistance, and have a high drying time and low glass transition temperature. An acrylic emulsion pressure sensitive adhesive exhibiting cohesion and heat resistance was developed and the present invention was completed.
본 발명의 아크릴계 에멀젼 점착제는 단량체의 조성을 변화시켜 유리전이온도와 극성을 적절히 변화시키고 점착성 부여수지나 액상고무 또는 일반 고체고무를 적절하게 사용하고 가교 가능한 작용기를 갖는 단량체를 적정량 사용하므로서 고도의 점착력과 응집력 및 내열성 등을 발휘할 수 있다.The acrylic emulsion pressure-sensitive adhesive of the present invention changes the composition of the monomer to suitably change the glass transition temperature and polarity, and suitably uses a tackifying resin, a liquid rubber or a general solid rubber, and uses an appropriate amount of a monomer having a crosslinkable functional group, thereby providing a high adhesive strength. Cohesion force, heat resistance, etc. can be exhibited.
