Water-based terrace phase-change epoxy putty coating and preparation method thereof

Abstract

The invention discloses a water-based terrace phase-change epoxy putty coating and a preparation method thereof. The water-based terrace phase-change epoxy putty coating is formed by compounding a component A, a component B and a component C; the component A comprises, by weight, 30-50 parts of a waterborne epoxy curing agent, 30-40 parts of deionized water, 0.1-0.3 part of a defoaming agent, 0.1-0.4 part of a dispersing agent, 0.2-0.6 part of a base material wetting agent, 0.8-1.2 parts of a leveling agent and 10-20 parts of a microcapsule phase change material; the component B comprises, byweight, 85-95 parts of waterborne epoxy resin and 5-15 parts of aliphatic glycidyl ether, and the aliphatic glycidyl ether meets the following requirements: (1) the viscosity at 40 DEG C is 3-7 mpa.s,and (2) the epoxy equivalent is 290-310 g / eq; and the component C comprises, by weight, 80-100 parts of 200-mesh quartz powder and 1.5-4.5 parts of a composite fiber. The addition of the microcapsulephase-change material and the composite fiber greatly improves the cracking resistance and adhesive force of the putty coating.

Description

technical field

[0001] The invention belongs to the technical field of paint preparation, and in particular relates to a water-based floor phase-change epoxy putty paint and a preparation method thereof. Background technique

[0002] Putty paint is a decorative material for leveling the surface of the wall. It is a thick paste paint and an indispensable product before the paint is painted. Applied on the primer or directly on the object to remove uneven defects on the surface of the object to be coated. The usual putty batching is to use slaked lime to level it first, and then to batch ordinary putty. This way, although it can save money, it will bury hidden dangers from then on. The slaked lime in the wall will react with carbon dioxide in the air to form calcium carbonate, which will expand in volume, causing the wall to crack and cause wall leakage, endangering the normal living of residents. In addition, due to the large thickness of the putty coating, during the dryin...
