Abstract

The present invention provides a method for preparing a matte anti-fingerprint stainless steel decorative plate. The method comprises the steps of: 1) selecting a polymer coating material, wherein the polymer coating material is formed by mixing a film forming material, an inorganic nano-filler, a solvent and an auxiliary agent, wherein the film forming material comprises the following ingredients based on the weight ratio: 30-50 parts of acrylate composite resin, 5-20 parts of amino resin, and 5-15 parts of epoxy resin; and 1-8 parts of a matting agent and 1-8 parts of an anti-settling agent are added; and 2) performing a spray coating using the polymer coating material, wherein a coating film has a thickness of 1.5-2.5 μm, the precision of the atomization air pressure of a spray gun is controlled at ±0.1 bar during spray coating, and the coating is dried to obtain a finished product and then a matte anti-fingerprint stainless steel decorative plate which has a high-standard matte and anti-fingerprint index is prepared.

Claims

1. A method for preparing a matte anti-fingerprint stainless steel decorative plate, comprising:

1) selecting a polymer coating material, wherein the polymer coating material is formed by mixing the following ingredients in weight ratio;

a film forming material, comprising 30-50 parts of acrylate composite resin, 5-20 parts of amino resin, and 5-15 parts of epoxy resin;

an inorganic nano-filler, in 1-5 parts;

a solvent, in 40-50 parts;

an auxiliary agent, in 10-20 parts;

1-8 parts of a matting agent; and

1-8 parts of an anti-settling agent;

wherein the polymer coating material has a PH value at about 4.8 to ensure film uniformity;

2) performing a spray coating using the polymer coating material to form a coating film, wherein the coating film has a thickness of 1.5-2.5 μ

m, and a precision of the atomization air pressure of a spray gun is controlled at ±

0.1 bar during the spray coating; and

drying the coating to obtain a finished product.

2. The method according to claim 1, further comprising:

pretreating before the spray coating step by washing the stainless steel plate by a neutral detergent, and rinsing the stainless steel plate with deionized water using ultrasonic wash.

3. The method according to claim 1, wherein the drying step further comprises

drying the stainless steel plate in a drying oven placed in a clean environment, wherein the oven is equipped with high temperature-resistant high-efficiency filter at an air inlet and an air outlet of the air passage of the oven, the filter has a filtering material coated with microporous fluorine resin.
