Resumen
This study analyzed if process oil and synthetic rubber, the main materials of the previous synthetic polymerized rubber gel waterproofing materials (P-SPRG), can be replaced with waste oil and waste rubber to be recycled as raw waterproofing materials as a part of expanding the recycling of waste resources to waterproof areas. The synthetic polymerized rubber gel waterproofing materials (W-SPRG), based on the mixture of waste oil and waste rubber, were primarily analyzed for the trend of viscosity changes according to the mixture ratio between waste oil and waste rubber and were secondarily tested for eight performances, including viscosity, solid content, water permeability resistance, wet surface adhesion, structural behavior responsiveness, underwater loss resistance, chemical resistance safety, and temperature safety. After testing, the viscosity was the highest when the mixture ratio of waste oil and waste rubber was in the range of 2:1, and wet surface adhesion, structural behavior responsiveness, and temperature safety were relatively improved. Moreover, the comparative analysis of performance between W-SPRG and P-SPRG showed that W-SPRG secured the more stable performance in viscosity, solid content, wet surface adhesion, underwater loss resistance, and chemical resistance safety. Based on the results of this study, it has been confirmed that recycled waste oil and waste rubber can be commercialized as raw waterproof materials. This is expected to contribute to improvements in the cost reduction and environmental pollution arising due to waste disposal and incineration.
