| 摘要 |
The present invention relates to a manufacturing method of a core material for a lamella type sun shade board comprising complex carbon materials which, in detail, includes the following steps: a mixed solution applying step which applies a mixed solution having an unsaturated polyester, a low shrinking agent, a hardening initiator, a polymerization retarder, a filler, a release agent and a viscosity agent; a glass fiber laminating step which laminates glass fiber on the upper part of the polypropylene film having the mixed solution applied through mixed solution applying step; and a pressurization step which pressurizes the laminated layers having undergone the drying stage that drives laminating layers produced through the glass fiber laminating step. |
