Problems solved by technology

[0003] The pump valve components of centrifugal pumps are often in contact with various liquid substances, especially on industrial pipelines, most of the liquids are corrosive, and the surface is easily rusted, which greatly affects the normal operation of pump valve components and reduces the service life. Therefore, the antirust treatment of pump valve parts is particularly important

Embodiment 1

[0017] A method for preparing environmentally friendly antirust oil for horizontal centrifugal pumps, comprising the following steps:

[0018] S1. Adjust the pH value of the aqueous anionic acrylic resin emulsion to make the pH value reach 5, heat to 60 ° C, add sodium hydroxymethyl cellulose, dibutyl phthalate, nano calcium carbonate and iron oxide after stirring, and then Heating to 70°C and stirring to obtain mixture A;

[0019] S2. When the temperature of mixture A drops to 50-60°C, add sodium dihydrogen phosphate and polyepoxysuccinic acid, and mix thoroughly to obtain mixture B;

[0020] S3. Add anti-rust additives and deionized water to the mixture B in sequence and mix them into the dispersion tank. Control the temperature of the reactor at 80°C, stir and disperse at a speed of 620r / min for 6min, then add titanium dioxide and defoamer After stirring evenly, add thickener 3800, adjust the viscosity to 4, continue to stir for 30 minutes, filter, and pack.

Abstract

The invention discloses a preparation method of environment-friendly anti-rust oil for a horizontal centrifugal pump. The environment-friendly anti-rust oil comprises the following raw materials in parts by weight: 13-16 parts of aqueous anionic acrylate resin emulsion, 5-8 parts of carboxymethyl cellulose sodium, 13-16 parts of dibutyl phthalate, 3-7 parts of nano calcium carbonate, 3-7 parts offerric oxide, 18-20 parts of sodium dihydrogen phosphate, 8-13 parts of polyepoxysuccinic acid, 10-13 parts of an anti-rust additive, 5-7 parts of titanium dioxide, 3-4 parts of an antifoaming agent and the balance of deionized water. Compared with the traditional technology, the method is simple in treatment process and low in cost, the anti-rust additive comprises a dispersing agent, an antifoaming agent, a flatting agent, mercaptoproxy trimethoxysilane and dodecyl succinic acid diethanolamide, and the mercaptoproxy trimethoxysilane and dodecyl succinic acid diethanolamide improve the anti-rust effect of the environment-friendly anti-rust oil. The environment-friendly anti-rust oil is water paint and is environmentally friendly to use.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly antirust oil for horizontal centrifugal pumps, and more specifically relates to a preparation method of environment-friendly antirust oil for horizontal centrifugal pumps. Background technique [0002] The centrifugal pump is designed according to the principle of centrifugal force. The high-speed rotating impeller blades drive the water to rotate and throw the water out, so as to achieve the purpose of transportation. There are many kinds of centrifugal pumps, which can be divided into civil and industrial pumps in terms of use, and can be divided into clean water pumps, impurity pumps, and corrosion-resistant pumps in terms of conveying media. [0003] The pump valve components of centrifugal pumps are often in contact with various liquid substances, especially on industrial pipelines, most of the liquids are corrosive, and the surface is easily rusted, which greatly affects the nor...
