High temperature resistance mirror-like silver resin

Abstract

The invention relates to a high temperature resistance mirror-like silver resin. A method for preparing the mirror-like silver resin comprises the following steps: based on 100 parts of the total weight parts, weighing 80 parts of a linear polymer compound, 7 parts of a double-bond-containing linear oligomer, 5 parts of MIBK (methyl isobuty ketone) 4-methyl-2-pentanon, 3 parts of isopropanol, and 5 parts of polymethyl acrylate; putting the materials in a stainless steel pot of 500-1,000ml sequentially; preparing a variable-speed high-speed disperser, mounting an explosion-proof motor and an anti-static switch on the disperser, and performing high-speed dispersion and low-speed dispersion sequentially. The high temperature resistance mirror-like silver resin has the beneficial effects of enduring high temperature of 300 DEG C without color changing, effectively improving the whiteness of the aluminum powder, increasing the covering power of metal pigment, resisting scrubbing of alcohol and other solvents and being excellent in aluminum powder arrangement and excellent in adhesion to various metals, glass and plastics, and can be cured at normal temperature, heated and cured at 180 DEG C for 30 minutes and cured by UV (ultraviolet ray).

Description

Technical field [0001] The invention relates to the fields of aluminum powder paint, electroplating silver oil for imitation electroplating and mirror silver ink, in particular to a high temperature resistant mirror silver resin. Background technique [0002] Electroplating silver, also known as mirror silver, is a relatively special metal pigment that has the effect of electroplating, so it is often called "electroplating silver" in the market. It is also known that vacuum aluminum metal pigments can be used as materials for their production. They are produced through a special vacuum aluminum plating process. Compared with aluminum pigments produced by traditional methods, this pigment is made of very smooth and very thin scaly aluminum flakes. The composition of the suspension, this pigment has a high reflective effect, and the ratio of its average particle diameter to its thickness is relatively large. [0003] However, there are no mature mirror silver coating products. Many ...

Problems solved by technology

[0003] However, there is no mature mirror silver coating product at present, and many traditional or imported materials are expensive, and cannot meet the requirements of electroplating silver oil and mirror silver ink used in aluminum powder paint and imitation electroplating on the market, as well as automotive wheel paint, Mobile phone casings, various electrical appliances, instruments and other high-end decorations; it should be pointed out that the existing similar products are easy to change color under high temperature conditions, which is not conducive to improving the whiteness of aluminum powder and the hiding power of metallic pigments

In addition, the compactness of the existing mirror silver paint film is poor, and the mirror effect will be lost after varnishing, and the protective effect of the paint film will be lost if it is not varnished.
