Abstract

The invention discloses a bridge and tunnel pavement waterproof bonding layer material and a preparation method and application thereof. The material comprises a water-borne epoxy resin, a water-borneepoxy resin curing agent aqueous solution, emulsified asphalt, a water-borne polyurethane emulsion, graphene oxide, mineral active ultrafine powder and the like. The preparation method comprises uniformly mixing waterborne epoxy resin, emulsified asphalt, waterborne polyurethane emulsion, graphene oxide and mineral active ultrafine powder to form a component A, taking a waterborne epoxy resin curing agent aqueous solution as a component B, and uniformly mixing the component A and the component B. According to the invention, the defects of high cost, low strength, poor toughness, poor cohesiveness and the like of the existing waterproof bonding layer material are overcome, and an environment-friendly material with low cost, high strength, good toughness, good durability, excellent cohesiveness and excellent waterproof performance is obtained.

Description

technical field [0001] The invention relates to a bridge and tunnel pavement waterproof bonding layer material and a preparation method and application thereof, belonging to the technical field of road engineering materials. Background technique [0002] The rapid development of urban modernization has made the requirements for road service levels more stringent. However, the construction of urban infrastructure, especially the road system, often lags far behind the needs of economic development. Urban traffic is not smooth, traffic congestion is becoming more and more serious, and road service levels are rapidly declining. Upgrading and reconstruction of urban roads has become an urgent matter. Therefore, urban Viaducts, urban tunnels, etc. continue to emerge, and bridge and tunnel projects have gradually become an important part of the urban traffic construction system, undertaking heavy traffic tasks. [0003] At present, the pavement pavement of urban bridges and tunnel...
