Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coatings, and more specifically to an anti-corrosion alkyd coating for wall surfaces. Background Art
[0002] As a traditional coating, alkyd coating has been widely used in many fields, including wall coating, due to its good adhesion, weather resistance, glossiness and relatively economical cost; however, alkyd coating also has some shortcomings and disadvantages in specific application environments, especially in terms of corrosion resistance, which may not be ideal, as shown below:
[0003] Hardness and wear resistance: Alkyd coatings have relatively low hardness and wear resistance and are susceptible to scratches and abrasion;
[0004] Limited resistance to chemical corrosion: When used on walls with strong chemical corrosion environments, the resistance to chemical corrosion is weak;
[0005] Water and moisture resistance: Not strong. Long-term exposure to a humid environment may cause the coating to bubble and fall off.
[0006] Environmental protection: Traditional alkyd paints may contain more volatile organic compounds (VOCs), which have certain impacts on the environment and human health; etc.
[0007] The existing {publication (publication) number: CN213015070U, a universal solid white alkali-resistant primer for interior and exterior walls} states that "it includes an alkali-resistant emulsion layer, an oil alkyd resin layer, a hydroxyl cellulose solution layer, a dispersant layer, a propylene glycol layer, a talc slurry layer, a thickener layer, a film-forming aid layer, an environmental protection aid layer, and a colorant layer, which are sequentially laminated"; although the alkali-resistant emulsion layer can improve the adhesion of the oil alkyd resin layer (a type of alkyd paint) when it is set, the effect is not good; and there is still no better compensation for the other shortcomings and deficiencies. Utility Model Content
[0008] The purpose of the utility model is to solve the above technical problems and provide an anti-corrosion alkyd coating for wall surfaces.
[0009] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0012] The primer layer and the intermediate layer are water-resistant and moisture-proof;
[0013] The middle layer is chemical resistant.
[0014] As a preferred technical solution of the utility model, the wall surface, the primer layer, the intermediate layer and the alkyd paint layer are arranged in sequence.
[0015] As a preferred technical solution of the utility model, the alkyd paint layer is a water-based alkyd resin paint layer or a high-solid content alkyd paint layer.
[0016] As a preferred technical solution of the utility model, the primer layer is an epoxy primer, and the epoxy primer is an epoxy zinc yellow primer layer.
[0017] As a preferred technical solution of the utility model, the intermediate layer is an epoxy intermediate paint layer, and the epoxy intermediate paint is a two-component epoxy mid-coat paint layer.
[0018] As a preferred technical solution of the utility model, the method further includes a varnish layer which is bonded and fixed to the outside of the alkyd paint layer to improve its wear resistance.
[0019] As a preferred technical solution of the utility model, the varnish layer is a polyurethane varnish or an acrylic varnish layer.
[0020] The beneficial effects of the utility model are as follows:
[0021] By sequentially arranging the primer layer 2 and the intermediate layer 3 between the wall surface 1 and the alkyd paint layer 4, the connection strength after the alkyd paint layer 4 is arranged is improved, the chemical resistance and the sealing property are improved to improve the water barrier property, and the service life is enhanced;
[0022] A varnish layer 5 is arranged outside the alkyd paint layer 4. The varnish layer 5 is a polyurethane varnish or an acrylic varnish layer with its high hardness and high gloss functionality to increase the hardness and wear resistance of the surface, improve the anti-fouling property and glossiness, and extend the life of the coating. BRIEF DESCRIPTION OF THE DRAWINGS
[0023] Figure 1 It is a structural schematic diagram of the utility model.
[0024] Figure numerals: wall surface-1, primer layer-2, intermediate layer-3, alkyd paint layer-4, clear varnish layer-5. DETAILED DESCRIPTION Embodiment 1:
[0025] like Figure 1 As shown, this embodiment proposes: an anti-corrosion alkyd coating for a wall, comprising a wall 1 and an alkyd paint layer 4 arranged on the outer side thereof;
[0026] The alkyd paint layer 4 is a water-based alkyd resin paint layer or a high-solid content alkyd paint layer, etc.;
[0027] Waterborne alkyd resin paint is a modified alkyd paint that uses water to replace most of the solvents in traditional alkyd paint, thereby significantly reducing the VOC content; while maintaining the good coating properties of alkyd paint, it is more environmentally friendly, has high hardness after drying, and has good weather resistance and corrosion resistance, making it suitable for wall painting;
[0028] High-solid alkyd coatings reduce the use of solvents and thus reduce VOC emissions by increasing the proportion of solid components; they are usually used for industrial and architectural surfaces that require higher performance and environmental protection, including walls, and can provide good corrosion resistance;
[0029] It also includes a primer layer 2 and an intermediate layer 3 (the primer layer 2, the intermediate layer 3 and the alkyd paint layer 4 can be provided by spraying or the like) which are arranged between the wall surface 1 and the alkyd paint layer 4 and are attached thereto to improve adhesion, so as to improve the connection strength after the alkyd paint layer 4 is provided;
[0030] The primer layer 2 and the intermediate layer 3 are water-resistant and moisture-proof, and the intermediate layer 3 is chemical-resistant, which improves functionality and enhances service life;
[0031] The primer layer 2 is an epoxy primer, and the epoxy primer is an epoxy zinc yellow primer layer, etc., which improves adhesion and has good sealing properties to improve moisture barrier properties;
[0032] The intermediate layer 3 is an epoxy intermediate paint layer, and the epoxy intermediate paint is a two-component epoxy mid-coat paint layer, etc., which improves the corrosion resistance to increase durability, and the thickness of the overall coating is to improve the moisture barrier property;
[0033] The wall surface 1, the primer layer 2, the intermediate layer 3 and the alkyd paint layer 4 are arranged in sequence, and a reasonable arrangement sequence is provided to ensure the functional performance. Embodiment 2:
[0034] like Figure 1 As shown, the difference between it and embodiment 1 is that: it also includes a varnish layer 5 bonded and fixed outside the alkyd paint layer 4 to improve its wear resistance, thereby improving functionality and extending service life;
[0035] The varnish layer 5 is a polyurethane varnish or an acrylic varnish layer, etc., which has high hardness and high gloss functionality to increase the hardness and wear resistance of the surface, improve the anti-fouling property and glossiness, and extend the life of the coating;
[0036] The varnish used, such as polyurethane varnish or acrylic varnish, also has good sealing properties, which can further prevent moisture penetration and enhance the moisture and water resistance of the entire coating.
[0037] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.
