Embodiment Construction

[0019] Take the following components by weight percentage respectively:

[0020] Nano gold particles 0.3%; Dispersant PA-1 0.4%; Hydroxyethyl cellulose 0.3%;

[0021] Preservative KS-2 0.1%; Heavy calcium 16.0%; Titanium dioxide 12.0%;

[0022] Wollastonite powder 8.0%; Talc powder 8.0%; Propylene glycol 3.0%;

[0023] Alcohol ester-12 1.5%; Leveling agent L-150 0.3%; NXZ defoamer 0.6%;

[0024] Pure acrylic emulsion 28.0%; water 21.5%.

[0025] The nano-gold particles are prepared by the chloroauric acid reduction method, and the particle size of the nano-gold particles is controlled within 20nm. Under normal temperature and pressure, put the above-mentioned various components in a mixer and stir for 80 minutes, and mix well.

Abstract

The invention discloses application of nanogold particles in paint. The paint added with the nanogold particles comprises the following components in percentage by weight: 0.001 to 3.0 percent of nanogold particles, 0.1 to 0.5 percent of dispersing agent, 0.1 to 0.5 percent of thickening agent, 0.1 to 0.2 percent of antiseptic agent, 10.0 to 25.0 percent of ground calcium carbonate, 5.0 to 20.0 percent of titanium pigment, 5.0 to 10.0 percent of wollastonite powder, 6.0 to 10.0 percent of talcum powder, 1.0 to 5.0 percent of antifreezing agent, 0.5 to 3.0 percent of film forming additive, 0.1 to 0.5 percent of levelling agent, 0.1 to 0.8 percent of antifoaming agent, 15.0 to 40.0 percent of latex, and 10.0 to 30.0 percent of water. By adding the nanogold particles to the paint, the content of organic pollutants in the paint is effectively reduced, and the environment-friendly property of the paint is improved.

Description

technical field [0001] The invention relates to the application of nano-gold particles in coatings and belongs to the field of chemical industry. Background technique [0002] Paints, latex paints and other coatings that are applied in different fields and have different functions and uses are widely used and closely contacted in people's daily life and industrial production. In the traditional forms of solvents and adhesives used in these coatings, it is inevitable to use toxic and harmful components such as volatile organic compounds (such as formaldehyde, benzene), which have a very serious impact on human health and environmental pollution. . [0003] Chinese patent application CN101020791A published on August 22, 2007 discloses a method for applying nanometer metal powder to plastics, rubber, coatings and paint modification. In this method, nano metal powder is mixed with inorganic compound carrier, and the high energy on the surface of nano metal powder is used to fo...
