Embodiment 1

[0056]Application on titanium alloy plates: Most titanium alloys are military products or precision instruments, which require metallic luster and good adhesion. Silver metallic glitter paint can be sprayed directly on the metal, and it can be stored after 1 hour of natural drying.

Embodiment 2

[0058] Application on non-standard containers: the sheet is hot-dip galvanized sheet, the color is consistent with the color of hot-dip galvanized sheet, air spraying is used during construction, and it is divided into inside and outside the box, and epoxy zinc-rich primer is used for leveling inside the box 1-2 minutes, then spray silver metallic glitter paint leveling for 1-2 minutes, spray silver metallic glitter paint directly outside the box, enter 40-60 ℃ drying tunnel to bake for 10-15 minutes, leave the drying tunnel to cool for about 2 minutes, and stack.

Embodiment 3

[0060] Application on aluminum alloys: decorative panels, aluminum alloy panels, and applications on building exterior walls, spray silver metallic flash paint directly, and then bake in an oven at 80°C for about 8 minutes, completely dry, and after cooling, storage.

[0061] The formulations of the silver metallic glitter paint used in the above three examples are as follows:

[0062]

[0063]

[0064] Production Process:

[0065] (1) The paint making equipment must be clean, check whether the stirring is regular and whether the paint outlet valve is closed.

[0066] (2) Use 3 materials to pre-disperse 2 materials, and use a stirring device with a motor power of 45 kilowatts at a dispersing speed of 800r / min to stir for 10 minutes until the uniform fineness of no dispersion is ≤ 20 microns. Component A is obtained.

[0067] (3) Use 5 ingredients to pre-disperse 3 ingredients, and use a stirring device with a motor power of 45 kilowatts at a dispersing speed of 800r / m...

Abstract

The invention belongs to the field of paint and particularly relates to paint special for the surface of special non-ferrous metal and a preparation method of the paint. The paint special for the surface of special non-ferrous metal comprises, by weight percentage, 65-68% of modified acrylic resin, 0.8-1.2% of bentonite, 7-11% of xylene, 0.1-0.3% of cellulose, 1-2% of butyl ester, 1-3% of dibutylester, 0.2-0.4% of leveling agent, 3-5% of non-floating type aluminum powder, 1-3% of adhesion promoter and 16-18% of toluene, wherein the modified acrylic resin is prepared by mixing butyl acetate, butyl acrylate, epoxy resin, methacrylic acid, styrene, methyl methacrylate, isopropyl methacrylate, toluene and benzoyl peroxide (BPO). The prepared paint special for the surface of special non-ferrous metal has the advantages that the paint is quick in drying and has super-high adhesion on the surface of the special non-ferrous metal, the paint film of the paint does not become sticky when meeting with heat, and the paint conforms to the national lead-free and environment-friendly regulations.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a special paint for the surface of special non-ferrous metals and a preparation method thereof. Background technique [0002] The special paints for special non-ferrous metal surfaces on the market are mainly ordinary one-component acrylic paints, which are formulated from ordinary thermoplastic acrylic resins. They have poor adhesion on non-ferrous metal surfaces, general weather resistance and corrosion resistance, and are easy to stick back when heated. And other issues. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the invention provides a special paint for the surface of non-ferrous metals, which is prepared by modifying acrylic resin and other additives. The topcoat product prepared by the method has super-strong adhesion, excellent weather resistance, excellent anti-corrosion performance, no sticking back when hea...
