This product consists of baseband and sizing glue. Baseband is made of natural rubber, synthetic rubber, polymer rubber, epoxy coal tar pitch and other additives mixed and hot-pressed on non-woven fabrics. After cutting into widths of125mm, 250mm and 400mm, the coil was harvested. Primer is solvent-free epoxy coal tar pitch sizing agent. After the primer is mixed in proportion, it is painted on the surface of steel or concrete, and RPC tape is wound or pasted. The primer wets the polypropylene non-woven fabric fibers on the RPC belt, and after curing, it forms polymer resin fiber reinforced epoxy coal tar pitch consistent with the anti-corrosion coating. Replacing the alkali-containing and wax-containing glass fiber cloth in the original epoxy coal tar pitch anticorrosive coating with polypropylene non-woven fabric greatly improves the mechanical strength and adhesion, reduces the water absorption, improves the resistance to chemical media and improves the electrical properties. It is an improvement and improvement of the anticorrosive coating of epoxy coal tar pitch glass cloth in the original GB50268 and SY/t0447 standards. The outer layer of RPC belt is rubber protective layer, which has low water absorption, excellent electrical properties, high temperature resistance and aging resistance, and will not rot in underground and water for a hundred years. The rubber outer layer has high toughness and elasticity, which can cushion the impact and friction of external forces and reduce the damage in construction and transportation.
The product is temperature-resistant, microorganism-resistant, chemical-resistant, aging-resistant, and has a long service life, with an expected service life of more than 60 years. Mechanical damage resistance, simple and quick construction method, no pollution in the construction process and environmental protection; It is suitable for external wall corrosion protection of buried and underwater steel pipelines, and then on-site joint repair and damage repair. It is also suitable for anticorrosion of steel storage tank bottom, waterproofing and leakage prevention of concrete structures such as sewage pools, roofing waterproof layers, ditches and tunnels.
