Problems solved by technology

However, most epoxy coatings on the market at this stage can only add some talcum powder, quartz powder and double fly powder. When Portland cement is added, Portland cement will destroy the interface properties of epoxy coatings, resulting in serious problems. Demulsificati

Abstract

The invention discloses an epoxy mortar coating and a preparation method thereof. The epoxy mortar coating special for the waterborne terrace is prepared from a component A and a component B. The component A is prepared from, by mass, 30-50 parts of an epoxy curing agent, 30-40 parts of deionized water, 0.1-0.3 part of an antifoaming agent, 0.1-0.4 part of a dispersing agent, 0.2-0.6 part of a base material wetting agent and 0.5-0.6 part of a leveling agent. The component B is prepared from 85-95 parts of epoxy resin and 5-15 parts of aliphatic glycidyl ether. The component C is prepared from80-100 parts of 80-120 quartz sand and 20-40 parts of 325 Portland cement. The epoxy mortar coating is low in VOC content and good in skid resistance, and a formed paint film is high in adhesive force, extremely high in hardness and excellent in water resistance and solvent resistance.

Description

technical field [0001] The invention relates to the technical field of preparation of architectural coatings, in particular to an epoxy mortar coating and a preparation method thereof. Background technique [0002] Water-based epoxy floor refers to the floor formed after construction with water-based epoxy resin coating as the primer, middle coat and top coat. The intermediate coating is also called surfacer, surfacer, etc. After the primer and putty are applied to the object to be coated, the sandpaper is smoothed. Before the topcoat is applied, a transitional layer is usually applied, which is the intermediate coating. The intermediate coating has the characteristics of good filling and leveling, low paint film strength, and easy polishing. It is used as a primer when the surface decoration is high. [0003] Compared with wall coatings, water-based epoxy flooring needs to have a certain load-bearing capacity. Therefore, a certain proportion of inorganic curing agent need...
