Abstract

An epoxy floor and its preparation method and construction process provided by the present invention, the raw materials of the epoxy floor are composed of A component and B component, wherein, A component is composed of modified water-based epoxy curing agent, water, PTFE ultrafine powder, potassium hexatitanate whisker, wetting agent, clay, leveling agent, titanium dioxide, barium carbonate, polyvinyl alcohol, silane coupling agent and phenylethylphenol polyoxypropylene polyoxyethylene ether Composition, wherein, component B is composed of modified water-based epoxy emulsion, water and active agent. Therefore, the content of volatile organic compounds in the ingredients is low, the environmental protection performance is good, and the prepared epoxy floor has strong adhesion, wear resistance and durability.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an environmentally friendly epoxy floor and its preparation method and construction process. Background technique [0002] At present, traditional craft floors are basically divided into two types: solvent-based and solvent-free. Among them, solvent-based floors contain more organic solvents, which are harmful to people's health and pollute the environment, while solvent-free floors The floor also contains reactive diluents, which have certain toxicity. With the gradual improvement of people's awareness of environmental protection, many countries have promulgated environmental regulations to limit volatile (VOC), so the water-based direction of the floor has become a trend. [0003] The key to water-based floor coatings is to realize the water-based curing agent. The US invention patent USA5962629 discloses a method for a W / O type polyamide epoxy resin curing agent, which improves the pe...
