    • The present invention relates to a silicone rubber clay composition and, more particularly, to a silicone rubber clay composition that has a proper strength (softness) in an uncured state to facilitate shape change and is capable of showing an excellent appearance in a cured state. According to the present invention, there is provided a silicone rubber clay composition that has a proper softness in an uncured compound state to facilitate shape change. According to the present invention, silica with a particle size of 7 to 50 nm and a specific surface area (BET value) of 50 to 300 m2/g is applied as a filling agent, and thus the silicone rubber clay strength can be controlled and problems of existing clay associated with easy form collapse can be improved. Also, a plasticizer that has a viscosity of 200 centipoise or less at 25°C is applied, and thus a plasticity increment can be controlled. Accordingly, the present invention can be reused in a non-hardened state over a long period of time and a solidification problem of existing clay can be improved. Also, the silicone rubber clay composition according to the present invention generates few surface bubbles in a cured state, and thus is capable of showing an excellent appearance.
    • 硅橡胶粘土组合物技术领域本发明涉及一种硅橡胶粘土组合物,更具体地说,涉及一种在未固化状态下具有适当强度(柔软度)以促进形状变化并且能够在固化状态下显示出优异外观的硅橡胶粘土组合物。 根据本发明,提供一种硅橡胶粘土组合物,其在未固化的化合物状态下具有适当的柔软性,以促进形状变化。 根据本发明,作为填充剂,使用粒径为7〜50nm,比表面积(BET值)为50〜300m 2 / g的二氧化硅,由此可以控制硅橡胶粘土强度, 可以改善与容易形状崩溃相关的现有粘土的问题。 此外,施加在25℃下粘度为200厘泊或更小的增塑剂,因此可以控制可塑性增量。 因此,本发明可以在非硬化状态下长期重复使用,可以提高现有粘土的固化问题。 而且,根据本发明的硅橡胶粘土组合物在固化状态下产生很少的表面气泡,因此能够表现出优异的外观。
