▎ 摘　　要

NOVELTY - Processing composite release film comprises (i) configuring base material solution, (ii) configuring solution of first composite layer and second composite layer, (iii) removing the bubbles of base material solution, heating and curing for the first time and forming a base layer film after curing, (iv) coating the first composite layer solution on substrate film, heating and curing for second time and forming a first composite layer after curing, (v) adding buffer particles and flame retardant particles on the surface of the first composite layer, and (vi) coating a second composite layer solution on the surfaces of the buffer particles and flame retardant particles, heating and curing for the third time. USE - The method is useful for processing composite release film. ADVANTAGE - The release film: has specific flame retardant in the condition of having a buffer.
