Problems solved by technology

[0002]Aluminum powder asphalt paint is a commonly used steel primer, which has the advantages of strong compactness, low water permeability, and good antirust effect; but on the one hand, due to the The floating type aluminum powder has strong activity, and when the temperature reaches above 30°C, it is easy to chemically react with the acidic substances and free impurities in the coal tar pitch, so that the metallic luster on the surface of the aluminum powder disappears, and at the same time, too much harmful gas is produced. On the other hand, because aluminum powder is easily oxidized and blackened in water and acid-base environment, aluminum powder asphalt paint is very easy to produce darkening of aluminum powder in the paint, pigment precipitation, construction sagging and other phenomena, so in use And the quality is very unstable in the process of storage, which limits its wide application, especially it cannot be used as a primer for steel ships

Embodiment 1

[0030] A new type of aluminum powder asphalt ship bottom paint, which is composed of the following components: 50kg of low-temperature coal tar pitch with a softening point of 50°C, 15kg of floating aluminum powder with a floating rate of 65%, 10kg of smelted zinc oxide, and 400 mesh silk 3kg of mica powder, 5kg of 400 mesh talc powder, 0.5kg of silicon dioxide, 1kg of CF-3008I modified polysaccharide resin, and 15.5kg of heavy benzene.

[0031] The concrete preparation method of above-mentioned novel aluminum powder asphalt ship bottom paint is as follows:

[0032] (1) Put coal tar pitch into the paint mixing tank, add smelted zinc oxide, sericite powder, talcum powder, heavy benzene under stirring, disperse and grind until the fineness is 60 microns;

[0033] (2) Add floating aluminum powder slurry, silicon dioxide, CF-3008I modified polysaccharide resin, and continue to disperse for 20 to 40 minutes. The degree that the aluminum powder does not exist in the form of particle...
