Problems solved by technology

[0003] At present, most of the floor coatings are oil-based materials and two-component water-based epoxy coatings. Most of the oil-based floor coatings contain benzene-based dilution solvents, which are toxic, cause great pollution to the environment, and threaten human health. It meets the requirements of environmental protection; however, with the improvement of people's awareness of environmental protection, coatings are developing in the direction of water-based, while the existing two-component water-based epoxy coatings have poor surface scratch resistance, poor aging resistance, and short service life

Abstract

The invention provides an aqueous environment-friendly anti-aging floor coating and a preparation method of the floor coating. The floor coating comprises components A and B in weight ratio of 4:1, wherein the component A comprises water, modified polyalcohol emulsion, wetting agent, dispersing agent, thickening agent, defoaming agent, flatting agent, filler and anti-settling agent and the component B comprises aqueous curing agent and drier. The preparation method of the invention comprises the steps of putting water, the thickening agent, the wetting agent, the dispersing agent, the defoaming agent and the filler in a dispersing vat to disperse at a high speed, adding the emulsion, a color paste, the anti-settling agent, an ultraviolet absorbent and the flatting agent, uniformly mixing and packaging to obtain the component A; and putting the aqueous curing agent and the drier in the dispersing vat to disperse for 10-20min, uniformly mixing and packaging to obtain the component B. The floor coating of the invention has the advantages of environmental friendliness, soft gloss, wear and shock resistance, simpleness and convenience for construction, ultraviolet and aging resistance, long service life and suitability of being used indoors and outdoors.

Description

technical field [0001] The invention relates to a floor paint, in particular to a water-based, environment-friendly and aging-resistant floor paint and a preparation method thereof. technical background [0002] Flooring is a building material that has entered China in recent years and is mainly used for laying the ground. The floor is suitable for places that require relatively high sanitary conditions and grounds that require resistance to stamping, corrosion and wear, such as underground parking lots, factory warehouses (passing forklifts), etc. [0003] At present, most of the floor coatings are oil-based materials and two-component water-based epoxy coatings. Most of the oil-based floor coatings contain benzene-based dilution solvents, which are toxic, cause great pollution to the environment, and threaten human health. It meets the requirements of environmental protection; however, with the improvement of people's awareness of environmental protection, the coatings ar...
