Abstract

The invention discloses a polymer repairing mortar. The polymer repairing mortar comprises 400-500 parts of cement, 500-600 parts of quartz sand, 1-5 parts of a high-molecular polymer, 5-15 parts of a polymer, 1-5 parts of silicon micropowder and 0.1-0.3 parts of wood fiber, wherein the high-molecular polymer is cellulose ether, and the polymer is re-dispersible latex powder. The purpose of the invention is to provide the polymer repairing mortar with the characteristic of long service life and no cracking, and a preparation method thereof.

Description

technical field [0001] The present invention relates to a kind of article commonly used in construction and its preparation method, more specifically, it relates to a kind of polymer repair mortar and its preparation method. Background technique [0002] Polymer repair mortar is a high-strength inorganic adhesive specially developed for ordinary cement mortar that is not suitable as a protective layer of thermal insulation materials. It can replace various organic adhesives and greatly improve the quality of thermal insulation systems. [0003] Polymer repair mortar is a new type of concrete repair mortar that has both the adhesiveness of polymer materials and the durability of inorganic materials; it has high compressive strength, rapid curing, and good bonding performance; it has good water retention and resistance Cracking, high alkali resistance, UV resistance; easy to operate, wet base construction, healthy and environmentally friendly. The construction steps become si...
