Abstract

The invention discloses an elastic epoxy resin waterproof coating which comprises components A and B, wherein the component A comprises the following components in parts by weight: 65-85 parts of epoxy resin, 5-10 parts of activity diluent, 5-10 parts of reaction type plasticizer, 5-20 parts of functional additive and 280-500 parts of functional filling agent; the component B comprises the following components in parts by weight: 20-30 parts of modified amine hardener, 1-2 parts of coupling agent and 1-2 parts of prompting agent. The waterproof coating disclosed by the invention can be directly firmly adhered to the surface of a cement substrate when used on the surface of concrete, and 20% of deformation, cracking and the like on the surface of the cement substrate is overcome.

Description

Technical field: [0001] The invention relates to the technical field of cement waterproofing in construction engineering, in particular to a coating for concrete surface waterproofing in a highly corrosive environment. Background technique: [0002] Elastic epoxy resin waterproof coating is a kind of film-forming material mainly composed of epoxy resin and modified amine curing agent, which contains a certain amount of reactive diluent, auxiliary agent, filler, accelerator and coupling agent. When the elastic epoxy resin waterproof coating is used, the components are mixed evenly, and then evenly coated on the surface of the cement substrate; during the curing process, part of the base material penetrates into the interior of the cement substrate, so that the interface is formed A solid whole to achieve excellent bonding strength; at the same time, the high cross-linking degree of epoxy resin is used to block the damage of the external corrosive environment; a certain elonga...
