Problems solved by technology

[0003] At present, these simulated copper coatings are mostly organic solvent-based coatings, such as using organic resin varnishes as film-formers, and this organic solvent-based simulated copper coating is used for the coating of utensils and decorations, especially for indoor When the decoration is painted, there is a large amount of organic solvents, residual plasticizers, and formaldehyde volatilization, and the emission of volatile organic compounds (VOC) does not meet the requirements, which is harmful to human health and does not meet environmental protection requirements.

Embodiment Construction

[0025] In order to facilitate understanding of the present invention, the present invention enumerates the following examples. Those skilled in the art should understand that the examples are only used to help understand the present invention, and should not be regarded as specific limitations on the present invention. Unless otherwise specified, various raw materials of the present invention can be obtained commercially; or prepared according to conventional methods in the art.

[0026] The formula of each component of water-based simulated copper coating is as shown in table 1 among the embodiment 1~12;

[0027] The preparation steps of the water-based simulated copper coating in Examples 1 to 12 are as follows:

[0028] Step (1): Add the aqueous electroplating silver dispersion and dimethylethanolamine into the mixing tank, stir at a low speed to neutralize;

[0029] Step (2): adding 80% to 90% of the total amount of coalescence aids under stirring conditions of 350-450 r...

Abstract

The invention discloses waterborne simulation copper paint. A formula of the waterborne simulation copper paint is prepared from: 40 to 50 parts of waterborne electrosilvering dispersion, 6 to 9 parts of dimethylethanolamine, 5 to 8 parts of film forming additives, 8 to 15 parts of methylated amino resin, 1 to 5 parts of waterborne directional anti-settling agent, 8 to 15 parts of waterborne crystal pearlescent powder, 1 to 5 parts of waterborne color paste, 1 to 5 parts of waterborne coupling agent and 8 to 15 parts of deionized water. According to the waterborne simulation copper paint, the waterborne electrosilvering dispersion and the methylated amino resin are used as main body film forming substances, and water is used as a diluting agent, so that the construction method is simple and basically consistent with an oil construction method, the performance can reach a solvent-type simulation copper paint effect, the VOC emission is also low, the environmental protection requirement can be met, and the requirement of the industrialized production can be well met.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based simulated copper coating which is safe, environment-friendly and highly simulated. The invention also relates to a preparation method of the water-based simulated copper paint. Background technique [0002] All kinds of utensils and decorations made of copper are deeply loved by people because of their noble atmosphere. For this reason, there are increasing utensils or decorations made by coating imitation copper paint on the surface of metal handicrafts or anti-theft doors. [0003] At present, these simulated copper coatings are mostly organic solvent-based coatings, such as using organic resin varnishes as film-formers, and this organic solvent-based simulated copper coating is used for the coating of utensils and decorations, especially for indoor During the painting of decorations, there is a large amount of organic solvents, residual plasticizer...
