And (4) performance testing:
(1) paint film condition: curing the waterborne epoxy resin floor paint provided by the embodiment and the comparative example under an ice bath condition, and observing the curing condition of a paint film by eye;
(2) paint film strength: testing the strength of the coating by using a resiliometer;
(3) corrosion resistance: and (5) testing the paint film condition for 500h by using a salt spray test box.
The waterborne epoxy resin floor paints provided in the embodiments 1 to 9 and the comparative examples 1 to 4 were tested according to the test method, and the test results are shown in table 1:
TABLE 1
From the data in table 1, it can be seen that: the waterborne epoxy resin floor paint provided by the invention can still be cured under the ice bath condition. By optimizing the mass ratio of the component A to the component B and limiting the type of the heat-release filler in the component B, the water-based epoxy floor paint can be flat and free from color change after being cured under the ice bath condition, the strength of the paint film can reach 52-60 MPa, and the paint film after being subjected to a salt spray test for 500 hours is still unchanged and does not fall off (examples 1-4 and 6-7).
Comparing example 1 with comparative examples 1 and 3-4, it is found that the lower addition amount of calcium silicate (comparative example 1), the replacement of calcium silicate with conventional silica (comparative example 3) or the direct addition of no calcium silicate (comparative example 4) can cause the obtained waterborne epoxy floor paint to be incapable of being normally cured under the ice bath condition.
Comparing example 1 with comparative example 2, it is found that too high calcium silicate content leads to too strong alkalinity, and further causes foaming, peeling and discoloration of the cured paint film of the waterborne epoxy floor paint.
Further comparison of example 1 and example 5 shows that the use of calcium hydroxide in place of calcium silicate as the exothermic filler results in longer cure times due to the slower exotherm upon contact of the calcium hydroxide with water.
Further comparing example 1 with comparative examples 8-9, it can be found that the mass ratio of the component A to the component B is not within the range defined in the application, which results in incomplete curing of the waterborne epoxy resin floor paint and sticky paint film surface.
The applicant states that the present invention is illustrated by the above examples to provide a waterborne epoxy floor paint, a preparation method and applications thereof, but the present invention is not limited to the above examples, i.e. it does not mean that the present invention must rely on the above examples to be implemented. It should be understood by those skilled in the art that any modification of the present invention, equivalent substitutions of the raw materials of the product of the present invention, addition of auxiliary components, selection of specific modes, etc., are within the scope and disclosure of the present invention.
