Abstract

The invention discloses epoxy seal paint which comprises a main material and a curing agent. The main material is prepared from, by weight, 15-25 parts of epoxy resin, 50-60 parts of xylene and 20-30 parts of n-butyl alcohol; the curing agent is prepared from, by weight, 45-60 parts of polyamide resin, 30-40 parts of xylene and 10-20 parts of n-butyl alcohol. When the epoxy seal paint is used, the main paint and the curing agent are uniformly mixed to be used according to the weight ratio of 5:1. The invention further discloses a preparation method of the epoxy seal paint. The epoxy seal paint is simple in component, convenient and fast to produce, convenient to construct, high in seepage force and capable of preventing concrete members from alkali efflorescence, good caking properties with a concrete base surface and polyurethanes class or fluorocarbon class finishing coat are achieved, and adhesive force is larger than 2.5 MPa.

Description

technical field [0001] The invention relates to waterproof materials, in particular to an epoxy sealing paint and a preparation method thereof. Background technique [0002] Epoxy sealing primer is mainly suitable for cement or concrete base surface treatment before coating, providing impermeability, easy cleaning and good adhesion surface for subsequent coatings, especially suitable for denser ground as an adhesive layer, such as high High-strength cement or concrete floors, treated terrazzo and marble surfaces, also suitable for use as a primer sealer before painting solvent-based exterior wall coatings. The existing epoxy sealer has poor compatibility with fluorocarbon paint or polyurethane paint, and the adhesion is not good, so it has been perplexing the research and development, production and construction of the paint. Contents of the invention [0003] The object of the present invention is to provide a kind of epoxy sealer with good adhesion and compatibility wit...
