Problems solved by technology

[0005] There are also oil-based architectural coatings on the market that can be applied to kitchen decoration, but the environmental protection and odor of oil-based architectural coatings cannot be popularized and applied, and they are also unacceptable for home decoration. Moreover, their use requirements are also relatively high, and it is not very easy to use. , these shortcomings greatly limit the application of oil-based architectural coatings in kitchen decoration
[0006] In summary, in the field of kitchen decoration, there is a lack of a two-component water-based epoxy latex paint composition that can replace ceramic tiles on the kitchen interior wall, and maintain good environmental protection and routine application performance

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.

Abstract

The invention provides a bi-component aqueous epoxy latex paint composition capable of substituting for ceramic tile. The composition is obtained by mixing a component A and a component B in a ratio of 100:(8+ / -1.0) (in parts by weight), wherein (a) the component A includes the following components in parts by weight: 40.0-50.0 parts of a first film-forming material, wherein the first film-forming material is acrylic emulsion grafted by a functional group capable of blending, cross-linking and curing with aqueous bisphenol A epoxy resin, the binding degree of the functional group is not less than 5%, the solid content is 42-45%, the glass transition temperature (Tg) is 53-57 DEG C, the minimum film-forming temperature (MFFT) is 25-30 DEG C, and the content of total volatile organic compounds (TVOCs) is not more than 500 ppm (tested according to a test method of GB 18582-2008); 4.0+ / -1.5 parts of a film-forming additive, wherein the film-forming additive is 2,2,4-trimethyl-1,3-pentanediol isobutyrate, dipropylene glycol butyl ether, diethylene glycol-2-ethyl hexyl ester or a combination thereof; 20.0-25.0 parts of pigment filler; 8.0-12.0 parts of a functional super-fine hard material, 7.0+ / -1.0 parts of a coating additive and acceptable parts of water; and (b) the component B is 100.0 parts of a second film-forming material.

Description

technical field [0001] The invention relates to a synthetic resin interior wall coating and a preparation method thereof, which is characterized by replacing ceramic tiles in the interior wall of the kitchen, and highlights the environmental protection and functionality of the product, and more specifically relates to a propylene copolymer as the main component. The latex paint of the film material is composed of component A and water-based bisphenol A epoxy resin as the film-forming material of component B mixed in a certain proportion to form a two-component water-based epoxy latex paint composition and a preparation method thereof. Background technique [0002] Water-based architectural coatings are fine chemical products with the characteristics of simple construction, environmental friendliness, environmental protection and health, and high added value. It is mainly used for decoration and protection on the surface of building walls, decorative building materials and ot...
