Embodiment 1

[0029] The raw materials of the embodiments of the present invention are all commercially available raw materials.

[0030] The composition of a metal water-based antirust agent is (take 1000g water-based antirust agent as an example):

[0031] Dibasic acid: content 98.5% ratio 15g

[0032] Triethanolamine: content 98% ratio 35g

[0033] Monoethanolamine: content 99% ratio 10g

[0034] Synthetic borate ester: content 70% ratio 100g

[0035] Polyethylene glycol: content 95% ratio 70g

[0036] Triazine fungicides: content 90% ratio 10g

[0037] Benzotriazole content 98% ratio 1g

[0038] Water: Proportion 759g

[0039] The steps of a preparation method of a metal water-based antirust agent are as follows:

[0040] (1) Add an appropriate amount of water into reaction kettle A, heat up to 40°C, then add dibasic acid to mix, then add triethanolamine and monoethanolamine and stir evenly, keep the temperature at 40-42°C for 4 hours, then add benzotriazepam The azole is fully ...

Embodiment 2

[0045] The composition of a metal water-based antirust agent is (take 1000g water-based antirust agent as an example):

[0046] Dibasic acid: content 98.5% ratio 12g

[0047] Triethanolamine: content 98% ratio 38g

[0048] Monoethanolamine: content 99% ratio 6g

[0049] Synthetic borate ester: content 70% ratio 74g

[0050] Polyethylene glycol: content 95% ratio 80g

[0051] Triazine fungicides: content 90% ratio 20g

[0052] Benzotriazole content 98% ratio 1g

[0053] Water: Proportion 769g

[0054] The steps of its preparation method are the same as in Example 1.

[0055] Mechanism of action of the present invention:

[0056] First, the organic acid reacts with triethanolamine and monoethanolamine to form a water-based antirust agent. The added synthetic boric acid ester provides a stable pH value and plays a synergistic antirust role with the antirust agent. The fungicide makes the antirust The agent working fluid does not rot and inhibits the growth of bacteria. A...

Abstract

The invention relates to a water-base metal antirusting agent and a preparation method thereof. The antirusting agent comprises the components by weight percentage of 1-3% of dicarboxylic acid, 3-4% of triethanolamine, 0.5-1% of monoethanolamine, 5-10% of synthesized borate, 3-10% of polyethylene glycol, 1-3% of antiseptic, 0.1-1% of benzotriazole and the balance of water. The preparation method mainly comprises the following steps of: firstly preparing an antirusting agent body and subsequently adding and mixing the antiseptic, the polyethylene glycol, benzotriazole and the like, thus preparing the antirusting agent. In the invention, the action mechanism is simple and scientific, the cleaning and antirusting effect achieves the best by the cooperative function of all components; the antirusting agent contains the antiseptic that can effectively prevent the antirusting agent from cankering during the memory and working process, the polyethylene glycol can help forming film so that theantirusting agent has good water-repellent function and the antirusting capability can be effectively improved.

Description

technical field [0001] The invention belongs to the field of antirust agents, in particular to a metal water-based antirust agent and a preparation method thereof. Background technique [0002] In manufacturing industries such as electronics, instruments, machinery, etc., the cleaning of metal parts is a key process that affects product quality. The rust prevention of parts after cleaning is particularly important. After cleaning, parts must be treated with antirust agents to keep them within the specified There will be no rust within a period of time. At present, most antirust agents are made of nitrite. This kind of antirust agent contains carcinogens. Direct contact with the human body is likely to cause skin cancer, and some antirust agents tend to remain on the surface of parts to form white spots, and the antirust effect is poor. [0003] By searching, a patent document (patent application number: 200610086252.6, name: preparation process of water-based rust preventiv...
