| Abstract |
This study analyzes the performance change characteristics (deterioration characteristics) of the self-adhesive waterproofing sheet when exposed
to a chemical deteriorated Environment according to the content of recycled butyl rubber, focusing on the adhesive strength (with CRC board
surface & between sheet joint). This study was conducted to prepare a database that can be applied to the formulation design for As a result
of the study, it was confirmed that the performance degradation occurs relatively large when exposed to an acid environment among chemical
degradation environments. Accordingly, the recycled butyl rubber content must be limited to 44% to achieve similar performance to the
recycled butyl rubber content of 67% of the untreated test sample. confirmed to be obtainable. Based on the above results, it was suggested
that the appropriate mixing range of recycled butyl rubber considering the performance degradation after field application when manufacturing
the self-adhesive waterproofing sheet is up to 44% compared to the total rubber content. |
