Description
Technical Field
The invention belongs to the technical field of preparation of antirust primer, and particularly relates to superfine slag micro powder antirust primer and a preparation method thereof.
Background
The existing data show that the economic loss caused by metal corrosion is as high as 7000 million dollars each year around the world, which is six times of the sum of natural disasters such as earthquake, flood and typhoon, and the metal corrosion loss accounts for 20-40% of the total metal yield each year, so the metal corrosion must be dealt with, wherein one of the most economic, effective and convenient measures is to adopt metal anticorrosive paint, the most important of the metal anticorrosive paint is metal antirust primer in anticorrosive paint, and during the period, antirust pigment is usually adopted as the main component of the antirust primer. However, these conventional rust preventive pigments have been now banned in many countries because they contain heavy metals such as lead, chromium, mercury, etc., and zinc and its derivatives have recently been restricted in use by the european union because they are harmful to aquatic organisms.
The high-titanium blast furnace slag is a waste resource produced in the iron making of the vanadium titano-magnetite, has the advantages of large yield and low cost, has the properties of stable property and strong covering power, and does not have relevant contents for applying the high-titanium blast furnace slag in the preparation of the anti-rust primer at present.

2. The tetraethoxysilane can be hydrolyzed to generate Si-OH groups during preparation, can react with superfine slag micro powder containing metal to form a cross-linked structure, and can also react with a metal base material serving as a bearing matrix, so that a good film forming system is formed, and the film forming effect of the prepared anti-rust primer can be further improved by matching with a film forming additive. In addition, the hydrolyzed Si-OH groups can be condensed in the drying process to form Si-O-Si bond crosslinking points with strong hydrophobicity, so that the water absorption of the prepared anti-corrosive primer is reduced, and the anti-corrosive effect of the primer is further ensured.
3. Aluminum tripolyphosphate and talcum powder added in the formula are used as a color paste system of the anti-rust primer, so that the color of the anti-rust primer is improved, and meanwhile, P in the aluminum tripolyphosphate is3O10 5-The metal component in the formula and the metal element on the surface of the metal base material can be chelated to form a corresponding chelate, so that a stable protective film is formed on the surface of the base material, and the antirust effect of the prepared antirust primer is further enhanced.
