Problems solved by technology

This not only requires a lot of financial and manpower for perennial anti-corrosion maintenance, but also has potential safety hazards.
[0003] As far as the current stock of science and technology is concerned, it is unrealistic to solve the corrosion problem from the steel structure itself. Generally, the cost of stainless steel is expensive, and the price is several to ten times that of ordinary high-quality steel of the same specification, and the service life is limited.
Other corrosion-resistant materials mainly have a series of problems such as insufficient strength, limited service life, and poor economy, and the use of paint to prevent metal corrosion is the most widely used, most effective and economical means
And because the organic volatiles in solvent-based coatings pollute the atmosphere

Embodiment 1

[0012] Weigh 15 grams of zinc phosphate and 10 grams of aluminum phosphate, add 200 ml of ammonia water with a concentration of 2% by weight, stir for 12 hours at a high speed of 2500 r / min, then filter the above-mentioned mixed solution with a 1000-mesh filter, and pour it into the filtrate Add 150 grams of BH-620 water-dispersible epoxy resin, 2 grams of BZ-1250 superfine talc powder, 6 grams of R-930 titanium dioxide and 4,5,6,7-tetrahydrothieno[3,2-C] 2 grams of pyridine hydrochloride, stirred at 500r / min for 20 minutes, then sanded with a sand mill, tested the fineness with a scraper fineness meter, sanded to below 50 μm, filtered through a 200-mesh filter, and packaged to obtain the coating finished product.

Embodiment 2

[0014] A water-based anticorrosion coating was prepared in the same manner as in Example 1, except that 4,5,6,7-tetrahydrothieno[3,2-C]pyridine hydrochloride was not used.

experiment example

[0016] Acid resistance is measured according to GB / T 9274-88 standard, alkali resistance is measured according to GB 9265-88 standard, and salt water resistance is measured according to GB 1763-79 standard.

[0017] The acid resistance, alkali resistance and salt water resistance of the coating in Example 1 were all normal at 1200 hours, while the acid resistance, alkali resistance and salt water resistance of the coating in Example 2 were all normal at 480 hours. There is a significant difference between the two (P<0.05). This shows that the addition of anti-corrosion additives greatly strengthens the anti-corrosion effect of the coating.

Abstract

The invention relates to water-base anticorrosive coating which is prepared from the following raw materials in parts by weight: 100 to 200 parts of BH-620 water dispersible epoxy resin, 10 to 20 parts of zinc phosphate, 10 to 20 parts of aluminium phosphate, 1 to 5 parts of a BZ-1250 superfine talcum powder, 1 to 10 parts of R-930 titanium dioxide, and 1 to 10 parts of a corrosion-resistant additive. The water-base anticorrosive coating provided by the invention has a better corrosion-resistant effect and has a wide prospect in industrial application.

Description

technical field [0001] The invention relates to the field of coatings, in particular, the invention relates to a water-based anticorrosion coating. Background technique [0002] Steel structure engineering is a structure mainly made of steel, which is one of the main types of modern building structures. The annual steel production in the world exceeds 1 billion tons. It is estimated that the scrapped steel equipment due to corrosion is equivalent to about 30% of the annual output, and about 1 / 3 of them are permanently lost due to unrecyclable, resulting in economic losses of up to ten thousand yuan. One hundred million U.S. dollars. In addition to a large number of steel structures being exposed to atmospheric corrosion outdoors, metal equipment around the coast and in chemical production are particularly severely eroded by corrosive media such as acids, alkalis, and salts. This not only requires a lot of financial and manpower to carry out perennial anti-corrosion mainten...
