Problems solved by technology

[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

Abstract

The invention relates to a water epoxy ground floor coating and its making method and constructing process, where one component is low-molecular weight liquid-state epoxy resin assorted with active diluter in a proper proportion, and the other component is a dispersoid with hydrophilic curing agent as the principal thing, containing water-borne curing agent, water, acid-resistant wearable color filler, various auxiliaries, etc. and its producing method is simple and mainly includes mechanical dispersing and mixing; it does need to clean paint-covered surface as used on humid basal surface; the paint film has excellent properties of oily products and unilateral permeability. It uses water as dispersing medium, has no VOC, safe and environmental-protection.

Description

technical field [0001] The invention relates to a water-based epoxy floor coating, a production method and a construction process thereof, and relates to a development technology and a construction technology of an architectural coating. Especially the development technology and construction technology of floor coatings. technical background [0002] Due to the existence of solvents in solvent-based floor coatings, it 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. The desire 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 ...
