Concrete thin-layer repairing polymer mortar and preparation method thereof

Abstract

The invention provides concrete thin-layer repairing polymer mortar and a preparation method thereof and relates to the field of mortar. The concrete thin-layer repairing polymer mortar is prepared from the following raw materials in weight ratio: two-component slow reaction type polyurea waterproof coating and a sand material, wherein the weight ratio of the two-component slow reaction type polyurea waterproof coating to the sand material is 1:(1-3). By utilizing the concrete thin-layer repairing polymer mortar, the problem that polymer mortar in the prior art cannot well repair a concrete building component can be solved, and the concrete thin-layer repairing polymer mortar has the advantages of good bonding performance, corrosion resistance and scour and wear resistance.

Description

technical field

[0001] The invention relates to the technical field of mortar, in particular to a thin-layer concrete repair polymer mortar and a preparation method thereof. Background technique

[0002] In the construction or repair of concrete building components, ordinary mortar often has quality problems such as leakage, cracking, low bond strength, and easy peeling after use. In places with severe erosion, such as spillways and water culverts, the damage to ordinary mortar is more serious. Polymer mortar is a new type of building material emerging in engineering in recent years. It is made by mixing organic polymers and sand. Adding a certain proportion of polymers with excellent performance to the sand can improve the cohesiveness of the mortar and enhance the erosion resistance.

[0003] Existing polymer mortars include acrylic emulsion mortar, epoxy mortar and single-component polyurea mortar, etc. These polymer mortars improve the erosion resistance of the mortar ...
