Embodiment approach

[0036] As a preferred embodiment of the present invention, it includes raw materials in the following weight ratio: two-component slow-response polyurea waterproof coating: sand material = 1: (1-2.5).

[0037] As a further preferred embodiment of the present invention, it includes raw materials in the following weight ratio: two-component slow-response polyurea waterproof coating: sand material = 1: (1-2).

[0038] By further optimizing the ratio of the two-component slow-response polyurea waterproof coating and sand, the cohesiveness, elasticity and aging resistance of the polymer mortar for repairing thin concrete layers can be further improved.

[0039] As a preferred embodiment of the present invention, the two-component slow-response polyurea waterproof coating includes the following raw materials in parts by weight:

[0040]Polyether polyol 2471 200-260 parts, polyether polyol DDL-2000 60-80 parts, polyether polyol DDL-1000 20-30 parts, 4,4'-dicyclohexylmethane diisocyan...

Embodiment 1

[0052] This embodiment is a polymer mortar for repairing a thin concrete layer. The weight ratio of the two-component slow-response polyurea waterproof coating to the sand material in the polymer mortar for repairing a thin concrete layer is 1:1. Among them, the two-component slow-response polyurea waterproof coating includes the following raw materials in parts by weight: 2471 230 parts of polyether polyols, 70 parts of DDL-2000 polyether polyols, 25 parts of DDL-1000 polyether polyols, 4, 90 parts of 4'-dicyclohexylmethane diisocyanate, 40 parts of T5000 polyether amine, 7 parts of amine chain extender, 120 parts of superfine calcium powder, 25 parts of solvent T-305, 13 parts of plasticizer, 65 parts of mica powder 15 parts of titanium dioxide, 7 parts of white carbon black and 4 parts of black carbon black for pigments and fillers.

Embodiment 2

[0054] This embodiment is a polymer mortar for repairing a thin concrete layer. The weight ratio of the two-component slow-response polyurea waterproof coating to the sand material in the polymer mortar for repairing a thin concrete layer is 1:1.5. Wherein, the composition of the two-component slow-response polyurea waterproof coating is the same as that of Example 1.

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 ...
