Abstract

The invention discloses rapid repair polymer mortar which is prepared from the following raw materials in parts by weight: 70-80 parts of sand, 12-15 parts of cement, 5-8 parts of coal ash, 5-8 parts of mineral powder, 2-5 parts of emulsion powder, 0.1-1 part of cellulose ether, 0.5-1 part of low molecular weight epoxy resin, 0.5-1 part of medium molecular weight epoxy resin, 1-5 parts of glycerol ester of rosin and 2-4 parts of a polyurethane thickener. Besides excellent performances of water-retention rate, shrinking percentage, compressive strength, layering degree and the like, the rapid repair polymer mortar disclosed by the invention also has a performance of rapid agglomeration, so that when the rapid repair polymer mortar is used for engineering repair, the rapid repair polymer mortar not only effectively avoids phenomena such as cracks and hollow protuberances at the repaired parts, but also can be effectively and widely applied to pavement pulverization and suncrack repair of high and cold and high-temperature regions with large temperature difference and complicated climate.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a polymer mortar. Background technique [0002] At present, the polymer mortar products on the market generally have the defect of long gel time. Therefore, when it is applied to pavement flourization and dry crack repair in areas with large temperature difference and complex weather such as high cold and high temperature, it is often due to polymer Mortar gel time is long and lead to repair failure. For this reason, the need for a polymer with short gel time and rapid repair is an urgent problem for those skilled in the art. Contents of the invention [0003] The invention provides a quick-repair polymer mortar, thereby solving the problem that the actual repair effect of the existing quick-repair polymer mortar is far from meeting the repair requirements of engineering design, thus resulting in repair failure. [0004] In order to solve the problems of the technologies des...
