Quick-drying type environmental protection water epoxy floor paint and preparation method thereof

Abstract

The invention discloses quick-drying type environmental protection water epoxy floor paint and a preparation method thereof. The floor paint consists of the following components in percentage by weight: component A: 34-36 percent of ternary water amine epoxy hardener, 0.1-0.3 percent of moistening agent, 8-12 percent of titanium pigment, 0.8-1.2 percent of gaseous phase silica, 0.2-0.6 percent of palygorskite, 14-16 percent of 800-porous silicon powder, 0.13-0.17 percent of mineral oil defoaming agent, 0.13-0.17 percent of organic silicon defoaming agent, and 37-39 percent of water, and the summation of weight ratios of the component A is one hundred percent; component B: 89.5-90.5 percent of epoxy resin, and 9.5-10.5 percent of epoxy activated diluent, and the summation of weight ratios of the component B is one hundred percent; and the component A and the component B are uniformly mixed according to a weight ratio of 4:1. The preparation method comprises the following three steps of preparing the component A, preparing the component B and preparing epoxy floor paint. According to the epoxy floor paint and the preparation method thereof, excellent property of the coating layer is obtained, the time of surface drying and actual drying is greatly shortened, the uniformity of the paint is better, the epoxy floor paint is environment-friendly, and has good compatibility with water color paste.

Description

【Technical field】 [0001] The invention relates to a quick-drying environment-friendly water-based epoxy floor paint and a preparation method thereof. 【Background technique】 [0002] Traditional two-component solvent-based epoxy floor coatings have been used for many years. While having good wear resistance, hardness, adhesion, compressive strength, chemical resistance, etc., their high VOC and low The ideal air permeability has caused application limitations. The traditional two-component solvent-based epoxy floor coating has extremely poor air permeability, and when it is applied to the base surface with heavy underground moisture, it is easy to cause bubbles, peeling and falling off of the paint film. [0003] Water-based coatings have become a trend, and water-based epoxy floor coatings appear in such an environment. Compared with solvent-based epoxy resin coatings, the paint film has a microporous structure, which allows water vapor to penetrate but liquid cannot penetr...

AI Technical Summary

Problems solved by technology

[0004] Although water-based epoxy floor coatings have significantly improved in terms of construction tolerance and environmental friendliness, their overall performance is not as good as that of traditional two-component solvent-based epoxy floor coatings. Domestic reports and water-based coatings available on the market Generally, the overall performance is poor, and it is rare to see excellent performances such as abrasion resistance, hardness, adhesion, impact strength, and chemical resistance, but at the same time, it has a water-based epoxy floor coating with fast drying speed and moderate activation period.

[0005] The water-based epoxy floor coatings on the market fail to optimize various performances, and often pay too much attention to certain performances while ignoring other performances, thus easily causing hidden dangers in application

For example, general paint manufacturers or users generally pay attention to the hardness, wear resistance and adhesion of floor paint, but they do not know that too high hardness tends to cause unsatisfactory impact resistance of the paint film, resulting in poor flexibility, brittle serious problem

However, a paint film that is too flexible will cause problems such as poor hardness and poor stain resistance.

[0006] For the traditional water-based epoxy floor paint, in addition to its poor impact resistance, there are also problems such as slow drying speed, long recoating time, and long storage time after construction.
