Problems solved by technology

Although the manufacturers producing hydrobromic acid have better economic benefits, the equipment and workshops are corroded by hydrobromic acid and its volatilized hydrogen bromide gas for a long time, which reduces the service life and increases the cost of equipment maintenance and maintenance. Replacement of capital investment; in addition, the volatilized hydrogen bromide gas has a very serious hazard to the health of the company's staff due to its strong toxicity, causing immeasurable losses to the company and individuals
[0003] In the prior art, chlorosulfonated polyethylene anti-corrosion coatings are often used for anti-corrosion treatment of hydrobromic acid equipment, but such coatings have serious deficiencies in performance indicators such as quick-drying and corrosion resistance. For example, chlorine When the sulfonated polyethylene anti-corrosion coating is used for anti-corrosion treatment of equipment, the anti-corrosion coating on the surface of the equipment is only effective within three months. After three months of use, the equipment will start to bubble and peel off, losing its anti-corrosion effect

Embodiment 1

[0020] formula:

[0021] Toluene 20kg, 120 # Gasoline 25kg, petroleum resin 10kg, VAE 15kg, DOP 6kg, neoprene 12kg, ethyl acetate 4kg, appropriate amount of pigment.

[0022] The production steps of the paint are: according to the formulation requirements, toluene, 120 # Gasoline is added to the reactor with agitator, then petroleum resin, VAE, DOP, neoprene, and ethyl acetate are added into the reactor, stirred and reacted for 1-2 hours, and finally an appropriate amount of pigment is added to continue stirring evenly, and finally sent to high shear Mix emulsifier and sand mill for grinding, and when the fineness of the material reaches below 60μm, it can be filtered and packaged as a finished product.

Embodiment 2

[0024] formula:

[0025] Toluene 39kg, 120 # Gasoline 10kg, petroleum resin 8kg, VAE 11kg, DOP 3kg, neoprene 9kg, ethyl acetate 10kg, appropriate amount of pigment.

[0026] The production steps are the same as in Example 1.

Embodiment 3

[0028] formula:

[0029] Toluene 30kg, 120 # Gasoline 15kg, petroleum resin 10.4kg, VAE 6kg, DOP 3kg, neoprene 10.6kg, ethyl acetate 6kg, appropriate amount of pigment.

[0030] The production steps are the same as in Example 1.

Abstract

The hydrobromic acid corrosion resisting paint is compounded with toluene, No. 120 gasoline, petroleum resin, VAE, DOP, neoprene, ethyl acetate and pigment in certain proportion. The preparation process includes mixing toluene and No. 120 gasoline inside a reactor with stirrer; adding petroleum resin, VAE, DOP, neoprene and ethyl acetate through stirring and reaction for 1-2 hr; adding pigment while stirring; grinding and filtering. The paint has the features of short drying time, high corrosion resistance, high water resistance, good ageing resistance, adaptability to various painting modes, etc.

Description

1. Technical field [0001] The invention relates to an anti-corrosion paint, in particular to a hydrobromic acid anti-corrosion paint. 2. Technical background [0002] Hydrobromic acid HBr is a strong acid with strong acidity and toxicity, and has great corrosive effect. Although the manufacturers producing hydrobromic acid have better economic benefits, the equipment and workshops are corroded by hydrobromic acid and the hydrogen bromide gas volatilized for a long time, which reduces the service life and increases the cost of equipment maintenance and maintenance. Replacement capital investment; In addition, the hydrogen bromide gas that volatilizes brings very serious harm to the health of enterprise staff because of its strong toxicity, and causes immeasurable losses to enterprises and individuals. [0003] In the prior art, chlorosulfonated polyethylene anti-corrosion coatings are often used for anti-corrosion treatment of hydrobromic acid equipment, but such coatings ha...
