Preparation of Slate-Plastic Composite

슬레이트에 단량체 methyl methacrylate를 침투시키고 감마선 및 촉매 가열법으로 중합시켜 슬레이트-플라스틱 복합체를 제조하였다. 제품의 성질은 휨강도, 내수성 내산성등에 현저한 증가를 나타내었으며, 중합조건에 의한 차이점도 그 원인과 함께 비교 검토하였다.

Slate-plastic composite was prepared by impregnating methyl methacrylate monomer into the slate and subsequent curing the monomer either by gamma radiation or by thermal-catalytic method. Experiments were carried out to determine the polymerization rate and to investigate the properties of the composite. Significant improvements in flexural strength, water absorbability and acid resistance were observed in the products. Differences in properties between the composites obtained via two different methods were discussed as well as the cause of such results.
