Composition for polymer mortar, polymer mortar as well as preparation method and application of polymer mortar
The invention relates to the technical field of building materials, and discloses a composition for polymer mortar, the polymer mortar and a preparation method and application of the polymer mortar. The composition contains cement, a polymer emulsion, a water-soluble polymer, sand, an expanding agent, a defoaming agent, a retarder, a water reducing agent and water. Relative to 100 parts by weight of cement, the content of the polymer emulsion is 80 to 120 parts by weight, the content of the water-soluble polymer is 0.04 to 0.2 part by weight, the content of the sand is 115 to 190 parts by weight, the content of the expanding agent is 2 to 8 parts by weight, the content of the defoaming agent is 0.1 to 0.6 part by weight, the content of the retarder is 0.01 to 0.15 part by weight, and the content of the water reducing agent is 0.4 to 1.5 parts by weight; the content of water is 0-10 parts by weight; the polymer mortar prepared from the composition provided by the invention has the repair requirements of early strength and low elastic modulus, and meets the maintenance requirements of high-speed railway skylight period repair.
