preparation example Construction
[0121] A kind of preparation method of the two-component water-based epoxy latex paint component that can replace ceramic tile in the kitchen interior wall construction of the present invention comprises the steps:
[0122] The various components of the composition component A described in claim 1 are mixed to obtain the component A of the two-component water-based epoxy latex paint that can replace tiles in the kitchen interior wall construction.
[0123] Afterwards, component A and component B (100% water-based epoxy resin) are mixed in a certain proportion, and the preferred ratio of the two components is 100:8±1.0, so as to obtain the effect of the replaceable ceramic tile on the kitchen interior wall. Two-component waterborne epoxy latex paint composition.
[0124] In a specific embodiment, the component A of the two-component water-based epoxy latex paint that can replace ceramic tiles in kitchen interior wall construction is made by the method comprising the following ste...
specific Embodiment approach
[0145] The present invention is further illustrated below by examples and comparative examples.
[0146] In the following implementation and comparative examples, component A of the two-component water-based epoxy latex paint that can replace tiles in the kitchen interior wall construction is investigated for its freeze-thaw stability, film-forming property, mildew resistance, and scrub resistance; and After component B is mixed, test the hardness of the paint film, the bending resistance, abrasion resistance and stain resistance of the paint film, etc.
