Embodiment 1

[0029] An embodiment of the novel water treatment agent of the present invention, said water treatment agent comprises the following components in mass percent:

[0030]

[0031] The water treatment agent described in this embodiment is prepared by the following method:

[0032] (1) At normal temperature and pressure, inject part of the water into the reaction kettle, and turn on the mixer;

[0033] (2) Slowly add zinc sulfate heptahydrate into the reaction kettle. After the zinc sulfate heptahydrate is completely dissolved, add polyaspartic acid and 2-phosphonic acid group-1, 2, 4 tricarboxybutane, and stir 30 minutes to get the premix;

[0034] (3) dissolving benzotriazole in the remaining water to form an aqueous solution of benzotriazole;

[0035] (4) Add the aqueous solution of benzotriazole to the premixed solution obtained in step (2), stir for 15 minutes and mix well to obtain the water treatment agent of this embodiment.

Abstract

The invention discloses a novel water treatment agent. The water treatment agent comprises the following components by mass percent: 20 to 25% of polyaspartic acid, 15 to 20% of 2-phosphonic-1, 2, 4 tri-carboxyl butane, 7 to 9% of heptahydrate, 1 to 2% of benzotriazole, and the balance of water. The novel water treatment agent is formed by the compounding of polyaspartic acid, 2-phosphonic-1, 2, 4 tri-carboxyl butane, heptahydrate, benzotriazole and water in a specific proportion; all the materials are synergistically interacted with each other, so that the corrosion inhibition and scale inhibition capability of the water treatment agent can be improved obviously; the water treatment agent is suitable for a cooling water system with high alkalinity, high hardness and high pH (Potential of Hydrogen) and can realize the operation in high cycles of concentration; in addition, non-phosphorus or low-phosphorous raw materials are adopted, which are harmfulless and easy for biodegradation, so that the green and environmental protection can be realized. The invention also discloses a preparation method of the water treatment agent; the water treatment agent prepared by the method can be stored stably for a long term.

Description

technical field [0001] The invention relates to a water treatment agent and a preparation method thereof, in particular to an efficient, multifunctional, green and environment-friendly water treatment agent and a preparation method thereof. Background technique [0002] In industrial circulating cooling water, chemicals added to control the hazards of scaling, corrosion, and biological slime are called water treatment agents. In the early stage of water treatment technology development, inorganic compounds, such as phosphate, chlorine, lime, etc., were generally added as water treatment agents, but the water treatment effect was limited to a certain extent. Later, it was developed to use pure natural organic compounds such as tannin, starch, lignin as water treatment agent, but because of its large dosage in water treatment application, it is easy to decompose under high temperature and pressure, and its impurity content is high, so it is rarely used. [0003] In the 1970s,...
