Problems solved by technology

[0002] With the popularization and development of various modern buildings, the requirements for waterproof materials in the field of construction engineering are increasing, and the requirements for their quality are getting higher and higher. At present, there are still many problems in the waterproofing of my country's construction industry, especially in coastal areas and Leakage of buildings in high-saline-alkaline areas is relatively serious. In some places, industries develop rapidly, there is air pollution, and acid rain occurs in some areas. These acids, alkalis, and salts can cause serious corrosion to buildings, bridges and other facilities. For this reason, traditional waterproof materials It is difficult to completely solve these problems
Although general waterproof materials can improve the waterproof performance of buildings, for areas where acid rain occurs, coastal areas and high-salinity areas, such materials will be corroded, and it is difficult to better complete the task of waterproofing and impermeability.

Abstract

The invention discloses an anticorrosive thermoplastic polyolefin (TPO) modified asphalt composite waterproof coiled material. The coiled material has a multilayer laminar structure formed by compounding and solidifying a TPO material layer, an adhesive isolation layer, an upper anticorrosive asphalt layer, a polyester filament non-woven fabric, a lower anticorrosive asphalt layer and a protective film layer, with a thickness of 2 to 5mm. A manufacturing method for the coiled material comprises the following steps of: conventionally manufacturing the TPO material layer, preparing an anticorrosive asphalt mixture constructed by a hot melting method and a normal temperature self-adhesive method, selecting the anticorrosive asphalt mixture according to the technical requirements, spreading the polyester filament non-woven fabric on a production line and guiding the polyester filament non-woven fabric into an immersion trough to immerse non-woven fabric in the anticorrosive asphalt mixture, and performing double-roll calendering and film coating, cooling, airing and coiling on the non-woven fabric and the TPO coiled material to form a finished product. The upper and lower layers of anticorrosive modified asphalt are wrapped on the polyester filament non-woven fabric, so the coiled material has predominant long-term acid, alkali and salt corrosion resistance; and No.90 road asphalt is used as a raw material, so the cost is low, and the preparation method is simple and scientific.
