Problems solved by technology

[0002] Now, epoxy materials still have a considerable share in the floor market. Based on its application in the domestic market for 20 years, although it also has some undeniable advantages, the shortcomings and disadvantages of epoxy materials are becoming more and more prominent. Exposure during use, such as: epoxy material is brittle, poor aging resistance, short service life, poor chemical resistance, poor water resistance, these series of problems bring troubles and losses to users who use it
[0003] Traditional epoxy floor coatings have average leveling properties and contain toxic substances such as benzene. Not only can they not be naturally leveled after construction and brushing, but the paint surface cannot be bright and smooth, and the existence of toxic substances is harmful to the user's body.

Embodiment 1

[0039] Coating of the present invention is mainly made up of main paint and solidifying agent of 20: 1 by weight ratio, wherein, main paint is the CYDW113-W50 type water-based epoxy resin of Baling Petrochemical by weight percentage of 43%, the R706 of 25% Du Pont Type titanium dioxide, 24.8% pure water, 1.5% Sunrise Chemical TM-3 coalescent, 0.9% BYK 194 dispersant, 2.4% BYK 028 disinfectant Foaming agent, 0.8% PCTS BIOX VFB1 type preservative, 0.5% PCTS BIOX CM type antifungal agent, 0.5% Rohm and Haas 3065 type associative thickener, 0.3% Lockwood ARM 259 type thickener agent and 0.3% of American Dow DOW AP 95 PH regulator; and the curing agent is composed of 30% pure water by weight, 50% CYDHD-W280 water-based epoxy curing agent of Baling Petrochemical and 20% Composed of Sunrise Chemical's TM-3 coalescent.

[0040] During preparation, firstly weigh corresponding main paint raw materials and curing agent raw materials respectively according to the above weight percentages...

Embodiment 2

[0050] Compared with Example 1, the present embodiment differs in the types and weight percentages of the dispersant and defoamer used in the main paint.

[0051] The main paint in the present embodiment is to be the CYDW113-W50 type water-based epoxy resin of 55% Baling Petrochemical by weight percentage, the R706 type titanium dioxide of 20.2% Dupont, 15% pure water, 2% sunrise chemical industry TM-3 film-forming aid, 1.2% Tego D168 dispersant, 3% BYK 028 defoamer, 1.2% PCTS BIOX VFB1 preservative, 1% PCTS BIOX CM antifungal agent, 0.6% Rohm and Haas 3065 associative thickener, 0.4% Lockwood ARM 259 thickener and 0.4% American Dow DOW AP 95 pH regulator.

[0052]The curing agent is composed of 35% by weight of purified water, 40% of CYDHD-W280 water-based epoxy curing agent of Baling Petrochemical and 25% of TM-3 film-forming aid of Sunrise Chemical.

[0053] The preparation steps of this paint are as follows:

[0054] First, at the rotating speed of the stirring vessel at...

Embodiment 3

[0062] The difference between this embodiment and Example 1 is that the dispersant used in its main paint is the FX600 type dispersant of Hemings, and what the defoamer adopts is the AD01 type defoamer of gas chemistry. The product of this embodiment The various test parameters are shown in Table 1.
