Epoxy self-leveling floor coating and preparation method thereof

Abstract

The invention discloses an epoxy self-leveling floor coating and a preparation method thereof. The epoxy self-leveling floor coating comprises a component A and a component B, wherein the mass ratio of the component A to the component B is (4:1)-(6:1); the component A is prepared from the following raw materials by weight percent: 35.0-38.0 parts of liquid epoxy resin, 5.0-10.0 parts of an epoxy active diluent, 0.3-0.5 part of a dispersing agent, 0.3-0.5 part of a defoaming agent, 1.0-2.0 parts of pigment, 10.0-15.0 parts of talcum powder, 15.0-20.0 parts of quartz powder, 20.0-25.0 parts of barium sulfate, 0.3-0.5 part of a flatting agent and 2.0-3.0 part of benzyl alcohol; the component B is a curing agent. The epoxy self-leveling floor coating is low in VOC (Volatile Organic Compound) and high in flowbility, can meet the environment-friendly theory, and is harmless to human bodies; a prepared paint film is smooth, bright and attractive in surface, the brightness is greater than 95%, and the effect of mirror surface is achieved; the paint film is low in viscosity, good in flowbility even at a low temperature, and high in drying speed; a high stirring method preparation process is adopted, so that the waste of raw materials is reduced, and the energy consumption is reduced.

Description

technical field

[0001] The invention belongs to the technical field of coatings, in particular to an epoxy self-leveling floor coating and a preparation method thereof. Background technique

[0002] In the middle and late part of the last century, many clean workshop floors appeared in Europe and the United States. It uses an integral polymer surface layer, called "epoxy flooring", and its main components are epoxy resin and curing agent. Epoxy floor coatings can be divided into two types: solvent-based and solvent-free. Although solvent-based epoxy floor coatings have the advantages of low cost, dense and hard paint film, high hardness, and low shrinkage, solvent-based epoxy floor coatings Terracotta coatings contain a lot of organic solvents, which will emit a certain amount of volatile organic compounds (VOC) during production, construction and curing, which is harmful to the environment and personnel.
