Epoxy resin emulsion modified cement-based patching material and preparation material thereof
The invention relates to an epoxy resin emulsion modified cement-based patching material and a preparation material thereof. The epoxy resin emulsion modified cement-based patching material is characterized by comprising the following raw materials in parts by weight: 100 parts of sulphate aluminum cement, 5 to 40 parts of epoxy resin emulsion, 5 to 20 parts of waterborne curing agent, 0.4 to 1.0 parts of accelerator, 2 to 10 parts of waterborne tackifier rosin resin emulsion, 0.2 to 1.0 parts of water reducer, 5 to 15 parts of silica fume, 40 to 60 parts of quartz powder and 10 to 30 parts of water. According to the epoxy resin emulsion modified cement-based patching material and the preparation material thereof disclosed by the invention, the sulphate aluminum cement and the accelerator are adopted so as to shorten the setting time of the patching material, therefore the underwater dispersion resistance of the patching material is improved; the mechanical property of the cement-based patching material and bonding strength between the cement-based patching material and a basement layer are improved by utilizing the epoxy resin emulsion; the prepared epoxy resin emulsion modified cement-based patching material has the characteristics of being short in setting time, high in underwater dispersion resistance, good in underwater bonding performance and the like, and can be used for concrete crack mending in underwater and humid environments.
