Problems solved by technology

[0002] The existence of solvents in traditional solvent-based floor coatings is harmful to people’s health and pollutes the environment. Especially in today’s shortage of oil resources, the price of solvents has risen rapidly. With the increasingly stringent environmental protection requirements of coating products and people’s The thirst for health makes the development of water-based coatings an inevitable trend
[0003] Because the resin and curing agent are in the solution in the molecular form of traditional solvent-based coatings, the system is a homogeneous system, so the curing is very complete, the paint film is very dense, and the air permeability is extremely poor. , due to the rise of underground water vapor to produce osmotic pressure on the paint film, when the osmotic pressure is greater than the adhesion between the paint film and the base layer, the paint film will be lifted up, showing as paint film bubbling, such examples are not uncommon

Embodiment Construction

[0033] As shown in Figure 1, the water-based epoxy floor paint of the present invention is a two-component emulsion paint, composed of A component and B component, and the A component includes water, water-based epoxy curing agent, auxiliary agent, filler, pigment, the B component includes liquid epoxy resin, reactive diluent, environment-friendly organic solvent, the ratio of the A component to the B component is 10:3, wherein the A component And the mass percentage that each component in the B component accounts for the total mass is:

[0034] A component:

[0035] Water: 30.9%;

[0036] Waterborne epoxy curing agent: 21.5%;

[0037] Additives: 1.7%;

[0038] Filler: 15.3%;

[0039] Pigment: 7.7%;

[0040] B component:

[0041] Liquid epoxy resin: 16.1%;

[0042] Active diluent: 3%;

[0043] Environmentally friendly organic solvents: 3.8%.

[0044] Among them, the additives are substrate wetting agent 1.2%, leveling agent 0.2%, and defoamer 0.3%.

Abstract

The invention discloses a water epoxy floor coating which is a double-component emulsion coating comprising a component A and a component B, wherein the component A comprises water, a water epoxy curing agent, an addition agent, a filler and paint; and the component B comprises liquid epoxy resin, a reactive diluent and an environmentally-friendly type organic solvent; and the proportion of the component A to the component B is 10:3. The water epoxy floor coating has the advantages of the avoidance of the environmental pollution and the harm to the health of the human body, strong ventilation property, suitability for moist base planes and satisfaction of environmentally-friendly requirements and can be widely applied to the field of the industrial floor coating.

Description

technical field [0001] The invention relates to the field of industrial floor coating, in particular to a water-based epoxy floor coating and a preparation method and a construction method thereof. Background technique [0002] The existence of solvents in traditional solvent-based floor coatings is harmful to people’s health and pollutes the environment. Especially in today’s shortage of oil resources, the price of solvents has risen rapidly. With the increasingly stringent environmental protection requirements of coating products and people’s The thirst for health has made the development of water-based coatings an inevitable trend. [0003] Because the resin and curing agent are in the solution in the molecular form of traditional solvent-based coatings, the system is a homogeneous system, so the curing is very complete, the paint film is very dense, and the air permeability is extremely poor. , due to the rise of underground water vapor to produce osmotic pressure on th...
