Problems solved by technology

[0006] In the prior art, anti-corrosion oil is often used as steel anti-corrosion. This anti-corrosion oil is not resistant to seawater and salt spray corrosion. Even if the anti-corrosion oil is applied to the steel, the steel will still corrode, which will cause great difficulties for the export of steel.

Embodiment 1

[0023] Formula: n-butanol 45Kg, 200# solvent oil 25Kg, diisobutyl phthalate 5Kg, phenolic resin 3.2Kg, styrene-butadiene rubber 5.8Kg.

[0024] The preparation steps of the metal anti-corrosion protective film are as follows:

[0025] According to the proportion of the formula, put n-butanol and 200# solvent oil into the reaction kettle with agitator and stir for 10 minutes to dissolve them evenly, then add phenolic resin and diisobutyl phthalate, and control the agitator to rotate at 1500-2400 Modification of the rotation speed per minute, react for 1.5-2 hours, finally add styrene-butadiene rubber, control the speed of the agitator to stir at 3600-4000 rpm for 1 hour, and filter and fill to obtain the finished product.

Embodiment 2

[0027] Formula: n-butanol 52.4Kg, 200# solvent oil 25.6Kg, diisobutyl phthalate 4.8Kg, phenolic resin 5.2Kg, styrene-butadiene rubber 5.8Kg.

[0028] The preparation steps are the same as in Example 1.

Embodiment 3

[0030] Formula: n-butanol 56Kg, 200# solvent oil 24Kg, diisobutyl phthalate 5.6Kg, phenolic resin 6.2Kg, styrene-butadiene rubber 5.4Kg.

[0031] The preparation steps are the same as in Example 1.

Abstract

The present invention provides the preparation process of anticorrosive metal paint. The anticorrosive metal paint is prepared with n-butyl alcohol 22-54 weight portions, 200#solvent oil 18-26 weight portions, diisobutyl phthalate 3-8 weight portions, phenolic resin 4-6 weight portions and butadiene styrene rubber 2-4 weight portions. The preparation process includes the following steps: throwing n-butyl alcohol and 200# solvent oil into reactor with stirrer and stirring for 10 min; adding diisobutyl phthalate and phenolic resin and stirring at 1500-2400 rpm for 1.5-2 hr; adding butadiene styrene rubber and raising the rotation speed to 3600-4000 rpm for high speed shearing for 1 hr; and finally filtering and packing. The paint can form protecting film fast, and the protecting film is acid and alkali resistant, water resistant, high in adhesion and weather resistant.

Description

[0001] 1. Technical field. [0002] The invention relates to an anti-corrosion protective film, in particular to a preparation method of a metal anti-corrosion paint. 2. Background technology [0003] Metal surface corrosion directly affects the quality of steel and greatly reduces the quantity of steel and affects the appearance. Therefore, corrosion will not only cause huge economic losses, but also damage environmental protection. Metal corrosion prevention is imminent, and it is urgent to solve it. [0004] At present, my country's steel production is advancing by leaps and bounds, and the steel output has reached 350 million tons. If the anti-corrosion is not in place, 1.75 million tons will be corroded in vain every year, resulting in a direct economic loss of 5.6 billion yuan. [0005] At present, 25.82 million tons of steel products are exported every year. These steel products have to travel at sea for three to four months from the time they are shipped to the port. A...
