Abstract

The invention relates to epoxy resin polymer mortar and a production process thereof. The mortar is prepared from the following components in parts by weight: 15-20 parts of epoxy resin slurry, 2-4 parts of an active diluent, 6-8 parts of a curing mixture and 70-80 parts of a base material which are mixed, stirred and mixed, wherein the epoxy resin slurry is prepared from bisphenol A epoxy resin E51, modified epoxy resin, organic bentonite and dioctyl phthalate; the active diluent is prepared from epoxy chloropropane, fatty alcohol and trichloropropane; the curing mixture is prepared from 85 parts of modified phenolic aldehyde amine, hydroxy-terminated liquid nitrile rubber, 2-(3, 4-expoy cyclohexyl) ethyl triethoxyl silane, lauryl phenylacetate and resorcinol; the base material is prepared from ordinary portland cement, quartz sands, hydrophobic expanded perlite, refined graphite powder and sericite powder. The epoxy resin polymer mortar provided by the invention not only has excellent mechanical property and wear resistance, but also has a good adhesive performance, and can be integrally formed with substrate concrete.

Description

technical field [0001] The invention relates to the technical field of polymer mortar, in particular to an epoxy resin polymer mortar and a production process thereof. Background technique [0002] The overflow surface, spillway, stilling basin, apron and other parts of the dam of the hydropower station are often washed by high-speed sandy water flow. The erosion and cavitation damage of the concrete on the overflow surface by high-speed sandy water flow is a common and important problem in the construction and operation of hydropower projects. Improving the anti-scouring and anti-cavitation capabilities of the concrete on the overflow surface is the solution to this problem. important way. Some large and medium-sized hydropower projects in Northwest China generally have high water head and high dam body, and the flow rate of water in the discharge channel is very high. The high-speed water flow entrains suspended and displaced matter, which is very harmful to the erosion a...
