Problems solved by technology
[0003] Epoxy resin is a commonly used material for the reinforcement and maintenance of roads, bridges and buildings. It has the advantages of high strength and short curing time. However, epoxy resin has insufficient toughness under dynamic load and is prone to brittle failure. In addition, epoxy resin cannot be used with Mixing with water is inconvenient for construction; therefore, the high-content water-based epoxy resin emulsion material of styrene-butadiene emulsion containing olefin polymer emulsion was invented to solve the above problems

Abstract
The present invention relates to a high-content aqueous epoxy resin emulsion combination containing toughening agent of styrene-butadiene latex, that is, the mixture of styrene-butadiene latex and high-content aqueous epoxy resin emulsion. The solidification of a solidifier is used to improve the performances of epoxy resin material. The weight percent of the styrene-butadiene latex and the high-content aqueous epoxy resin emulsion is: 1 to 10 portion of styrene-butadiene latex; 100 portion of high-content aqueous epoxy resin emulsion; the solidifier is 20 percent to 25 percent of the aqueous epoxy resin emulsion. The performances of the epoxy resin mixed with the styrene latex are improved. The technical indicators and utilization performances of the tenacity in strengthening and maintenance of roads and bridges are all superior to the ordinary epoxy resin, which can better meet the utilization performances of roads and bridges and extend the service life of roads and bridges. The time for enclosing traffic for maintenance and conservation is greatly shortened; the construction and operation are simple; the work efficiency is improved.
Description
technical field [0001] The present invention relates to a kind of epoxy resin emulsion composition that is used for road bridge and building reinforcement and maintenance, especially relate to a kind of styrene-butadiene emulsion containing olefin polymer emulsion, the high content that can improve bonding performance and strengthen toughness Waterborne epoxy resin emulsion material. Background technique [0002] With the rapid development of the national economy, the number and mileage of urban and rural transportation roads are increasing, the traffic load is becoming more and more heavy, and the overloaded vehicles are becoming more and more serious, which accelerates the damage of cement pavement. Therefore, strengthening the research on the maintenance and repairing technology of concrete pavement, and how to prolong the service life of concrete pavement is a relatively urgent subject. [0003] Epoxy resin is a commonly used material for the reinforcement and maintenan...
