preparation example Construction

[0035] The preparation method of cleaning antirust agent of the present invention, this method comprises the following steps:

[0036] Add metered deionized water into the reaction kettle; first add citric acid, ammonium nitrate, ethylenediamine tetraacetate under stirring, then add solubilizer, scale inhibitor dispersant, corrosion inhibitor and penetrating agent to make it fully Dissolve; adjust the pH value with citric acid or ammonia water, filter, take samples for inspection, and repackage after passing the test.

[0037] The present invention uses the method for descaling and antirust of described cleaning antirust agent, and this method comprises the following steps:

[0038] Add the cleaning antirust agent into the antifreeze coolant of the water tank of the motor vehicle. After the vehicle is idling for a predetermined time, open the drain valve of the water tank to discharge the cleaning antirust agent, and add new antifreeze coolant into the water tank.

Embodiment 1

[0040] Add metered 69g deionized water in the batching reactor, under stirring action, add 10% citric acid (10g), 5% ammonium nitrate (5g), 3% edetate disodium (3g), 5% % ethylene glycol monobutyl ether (5g), 2% acrylic acid-2-acrylamide-2-methylpropanesulfonic acid copolymer (AA / AMPS) (2g) and 1% benzotriazole (1g), 2% % hexamethylenetetramine (2g), then add 1% polyaniline nano-dispersion (1g), 2% sodium diisooctyl succinate sulfonate (2g), high-speed stirring made it fully dissolve in 20~30 minutes, finally Adjust the pH value to 3.5-4.5 with citric acid or ammonia water, filter, take samples for inspection, and pack.

Embodiment 2

[0042] Add metered deionized water into the batching reaction kettle, and add 10% citric acid, 4% ammonium nitrate, 4% disodium edetate, 5% ethylene glycol monoethyl ether, 3% hydrolyzed horse To acid anhydride (HPMA), then add 1% lan826 corrosion inhibitor, 0.5% polyaniline nano-dispersion, 3% polyether modified polydimethylsiloxane, stir at high speed for 20-30 minutes to fully dissolve, and finally use Adjust the pH value to 3.5-4.5 with citric acid or ammonia water, filter, take samples for inspection, and repackage.

Abstract

The invention discloses a cleaning antirust agent, a preparation method for the cleaning antirust agent and a method for removing scale and preventing rust by using the cleaning antirust agent. The cleaning antirust agent mainly comprises the following components in percentage by weight: 5 to 15 percent of citric acid, 3 to 12 percent of ethylene diamine tetraacetic acid salt, 1 to 5 percent of ammonium nitrate, 5 to 15 percent of dirt dispersion agent, 1 to 5 percent of penetrating agent, 0.5 to 3 percent of corrosion inhibitor, 1 to 6 percent of solubilizing agent and the balance of deionized water. Due to the adoption of the efficient penetrating agent and corrosion inhibitor in the cleaning antirust agent, scale deposit on the inner wall of a water tank of an automobile can be cleaned within a short time, so that matrix metal is protected in the cleaning process, a corrosion inhibition film clad layer is formed on the water tank, the corrosion resistance of the water tank is improved, and the cleaning antirust agent is convenient to use.

Description

technical field [0001] The invention relates to the field of chemical cleaning agents, in particular to a cleaning and antirust agent that effectively cleans scale and has an antirust function, a preparation method of the cleaning and antirust agent, and a method for removing scale and preventing rust using the cleaning and antirust agent. Background technique [0002] Limescale typically forms on the walls of containers, such as the inside of a water tank in a motor vehicle. The main components of scale are calcium carbonate and magnesium carbonate. The deposited scale is not conducive to the heat dissipation of the container and affects the uniform heating of the container. For example, when the scale of the car water tank reaches 0.5mm, it will make the water tank unable to dissipate the temperature normally, which will affect the heat dissipation of the cooling system. When the scale on the inner wall of the water tank exceeds 0.8mm, it will cause poor water circulatio...
