preparation example Construction

[0036] The preparation method of antirust agent comprises the steps:

[0037] (1) Mix rosin and maleic anhydride evenly, heat to 170-200° C., and keep warm for 10-20 minutes to obtain maleic rosin;

[0038] (2) Add the diethanolamine to the maleated rosin in the step (1), mix uniformly, leave standstill for 15-30min, and obtain the first product of the antirust agent;

[0039] (3) Add Span and glycerin to the primary product of the antirust agent in step (2), and stir evenly to obtain the antirust agent.

Embodiment 1

[0041] The water-soluble quenching agent of the present invention takes raw materials according to the following weight: hydroxymethylcellulose 4g, sodium chloride 0.4g, sodium benzoate 2g, phenylacetic acid lauryl 0.5g, sodium hydroxide 0.1g, rust inhibitor 0.8g , water 92.2g.

Abstract

The invention discloses a water-soluble quenching agent. The agent comprises the following raw materials of, in percentage by weight, 4%-5% of hydroxymethyl cellulose, 0.2%-0.4% of sodium chloride, 2%-3% of sodium benzoate, 0.2%-0.5% of laurate alcohol ester phenylacetate, 0.1%-0.8% of sodium hydroxide, 0.8%-1.5% of an anti-rust agent and the balance water. The preparation method comprises the following steps that firstly the hydroxymethyl cellulose and the sodium chloride are added into the water, the mixture is heated, stirred and dissolved, and then naturally cooled, then the sodium benzoate and the laurate alcohol ester phenylacetate are added, the mixture is uniformly stirred, then the sodium hydroxide is added, the mixture is uniformly stirred and left to stand, then the anti-rust agent is added, and the mixture is uniformly stirred to obtain a quenching agent finished product. The water-soluble quenching agent is safe, non-toxic and pollution-free during use, strong in anti-aging performance, good in rust resistance and capable of effectively preventing a steel part from being deformed and cracked when the steel part is quenched.

Description

technical field [0001] The present invention relates to the technical field of quenching agent, and more specifically relates to a water-soluble quenching agent. Background technique [0002] With the advancement of science and technology, people have entered a deeper understanding of the influence of cooling rate on the final performance of products in the quenching process, and quenching agent, as a main factor controlling the cooling rate in the quenching process, has become the subject of people's research. [0003] However, the cooling rate of the quenching agent in the prior art is not easy to control, and the antirust and antibacterial properties are poor. [0004] Therefore, how to provide a quenching agent that is easy to control the cooling rate and has strong antirust and antibacterial properties is an urgent problem to be solved by those skilled in the art. Contents of the invention [0005] In view of this, the present invention provides a water-soluble quenc...
