COMPOSITION FOR REPAIRING AND REINFORCEMENT OF CRACKS USING EPOXY RESIN AND METHOD FOR REPAIRING AND REINFORCING CRACKS USING SAME

摘要

The present invention relates to a composition for repairing and reinforcement of cracks and a method for repairing and reinforcing cracks using the same. The composition includes, based on 100 parts by weight of epoxy resin: 5-30 parts by weight of calcium sulfoaluminate; 5-50 parts by weight of calcium carbonate; 10-30 parts by weight of nanoceramic particles; 5-20 parts by weight of a curing agent; 3-15 parts by weight of a shrinking-reducing agent; 3-15 parts by weight of methyl methacrylate; 1-5 parts by weight of octyl triethoxysilane; 2-10 parts by weight of polyvinyl alcohol powder; 1-10 parts by weight of an adhesion enhancing agent; 1-10 parts by weight of a dispersant; 1-10 parts by weight of an emulsifier; and 1-10 parts by weight of a thickener. The composition improves adhesiveness inside of the cracked portions and provides excellent water-proof properties and increased long-term durability.;COPYRIGHT KIPO 2020
