Method for preparation of an adhesive sheet

The present invention relates to a method for producing an adhesive sheet. According to the method for producing the adhesive sheet, it is possible to produce adhesive sheets which are not cured until the adhesive sheets are applied to components but are cured after applied to the components when a temperature is raised by heat application, thereby remarkably increasing user convenience. To this end, the method for producing the adhesive sheet comprises the following steps: supplying a curing agent composition through an internal pipe of an electrospraying dual supply nozzle, and supplying a polymeric composition including polyvinylidene fluoride (PVDF) through an external pipe of the electrospraying dual supply nozzle; producing a potential curing agent by spraying the curing agent composition and the polymeric composition to a substrate through the electrospraying dual supply nozzle; producing a composition for forming the adhesive sheet by mixing the potential curing agent and an acrylic compound; and applying the composition for forming the adhesive sheets on a film. 본 발명에 따른 점착시트의 제조 방법은, 점착시트를 부품에 적용하기 전까지는 경화를 억제하면서도, 점착시트를 부품에 적용한 후에는 가열에 의하여 온도를 높였을 때 경화가 진행될 수 있는 점착시트를 제조할 수 있어, 사용의 편의성이 현저히 향상되는 효과가 있다.
