Abstract

The invention provides polymer repair mortar and a preparation method thereof. The polymer repair mortar comprises the following components in parts by weight: 54 to 55 parts of rubber powder, 164 to 164.3 parts of a water reducing agent, 10 to 11 parts of cellulose ether, 10 to 11 parts of starch ether, 5 to 6 parts of a defoaming agent, 24 to 25 parts of an expanding agent, 1700 to 1764.4 parts of water, 20 to 24.3 parts of polyvinyl alcohol, 4470 to 4490.3 parts of cement, 390 to 394.3 parts of slag powder, 42.1 to 43.8 parts of micro beads, 1505.55 to 1506 parts of washed yellow sand and 1505.55 to 1506 parts of quartz sand. The polymer repairing mortar mainly takes an inorganic material as a reinforcing material, is convenient and simple in material taking and low in price, and can be matched with an alkali-resistant glass fiber mesh to repair and reinforce a masonry wall; and the polymer repair mortar has good tensile adhesive strength, and is beneficial to enhancing the stability of the masonry wall.

Description

technical field [0001] The present application relates to the technical field of repairing mortar, in particular to a polymer repairing mortar and a preparation method thereof. Background technique [0002] Construction mortar is a mortar that bonds masonry block materials (bricks, stones, blocks) into a whole. Traditional building mortars suffer from low tensile bond strength, resulting in low stability of masonry walls repaired or reinforced using them. Contents of the invention [0003] The purpose of this application is to provide a polymer repair mortar and a preparation method thereof for the above problems. [0004] In a first aspect, the application provides a polymer repair mortar, comprising the following components in parts by weight: [0005] [0006] According to the technical solution provided by some embodiments of the present application, the polymer repair mortar includes the following components in parts by weight: [0007] [0008] [0009] A...
