Problems solved by technology

However, with the acceleration of industrialization in our country, there are more and more pollutants such as industrial waste gas and automobile exhaust in cities. These pollutants will significantly affect the durability and stain resistance of fluorocarbon coatings; Organic coatings release large amounts of fumes, which can easily lead to suffocation

[0041] Aluminum alloy curtain wall light blue ceramic coating formula

[0042]

[0043] The preparation method of light blue ceramic crystal coating for aluminum alloy curtain wall is as follows:

[0044]Step 1. In the batching tank, add the raw materials of organic modifier, wetting and dispersing agent and ethylene glycol ether acetate in sequence according to the weight fraction, and mix evenly;

[0045] Step 2. Slowly add titanium dioxide (TS-6200), fumed silica and cobalt blue into the batching tank according to the weight fraction and disperse evenly, and then use a sand mill to grind to a fineness of ≤25um;

[0046] Step 3, add aluminum silicate sol and isopropanol paint in turn, mix well;

[0047] Finally, after degreasing and degreasing the aluminum plate, use 120-mesh corundum for sandblasting, then use high-pressure air to remove dust, mix the paint evenly and then spray it. The thickness of the paint film is controlled at 20-30um.

Abstract

The invention discloses a ceramic crystal coating for metal surfaces and a preparation method thereof. The ceramic crystal coating for metal surfaces is composed of nano-oxides or nano silicate colloids, high-temperature-resistant pigments and fillers, organic modifiers and additives, has the characteristics of high temperature resistance, no stain sticking, super weather resistance, super wear resistance, non combustion, fire prevention and high hardness, can be used on the surfaces of iron and steel or aluminum alloys required to be high-temperature-resistant and wear-resisting, and also can be applied to the coating of aluminum sheets, aluminum honeycomb panels or other metal plates for outdoor and indoor decoration.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to inorganic-based coating compositions. Background technique [0002] The existing non-stick pans have been used around the world for decades, but the debate on it has never stopped. Until a few years ago, the U.S. Environmental Protection Agency (EPA) released the results of long-term follow-up tests, and finally made a ruling, ordering eight chemical companies including DuPont to gradually reduce or stop using the core components required to manufacture Teflon non-stick coatings Ammonium perfluorooctanoate (PFOA). In addition, according to the requirements of the EPA, the use of PFOA should be reduced by 95% in 2010, and its use should be completely banned by 2015. In addition, the high temperature resistance of Teflon non-stick pans is not good, and the risk of coating decomposition increases greatly when the temperature is higher than 250 ° C. Once these organic coatings are...
