Embodiment 1

[0029] Example 1 A long-acting water-based rust inhibitor

[0030] It includes the following components by weight percentage:

[0031]

[0032]

[0033] The preparation method is:

[0034] (1) Take the formula amount of water and heat it to 70°C, add the formula amount of sodium benzoate, triethanolamine borate, anti-flash rust agent and sebacic acid while stirring, and stir until completely dissolved to obtain a mixed solution A;

[0035] (2) After cooling the mixed solution A obtained in step (1) to room temperature, add glycerin, polyethylene glycol and defoamer in the prescribed amount and stir for 80 minutes to obtain the mixed solution B;

[0036] (3) Add the organic high polycarboxylic acid metal compound in the prescribed amount to the mixed solution B obtained in step (2) while stirring, and after stirring for 20 minutes, the water-based rust inhibitor is obtained.

Embodiment 2

[0037] Example 2 A long-acting water-based rust inhibitor

[0038]

[0039] The preparation method is:

[0040] (1) Take the formula amount of water and heat it to 50°C, add the formula amount of sodium benzoate, triethanolamine borate, anti-flash rust agent and sebacic acid while stirring, and stir until it is completely dissolved to obtain a mixture A;

[0041] (2) After cooling the mixed liquid A obtained in step (1) to room temperature, add glycerin, polyethylene glycol and defoamer in the formula amount and stir for 40 minutes to obtain mixed liquid B;

[0042] (3) While stirring, add the organic high polycarboxylic acid metal compound in the prescribed amount to the mixed solution B obtained in step (2), and after stirring for 40 minutes, the water-based rust inhibitor is obtained.

Embodiment 3

[0043] Example 3 A long-acting water-based rust inhibitor

[0044]

[0045] (1) Take the formula amount of water and heat it to 55°C, add the formula amount of sodium benzoate, triethanolamine borate, anti-flash rust agent and sebacic acid while stirring, and stir until it is completely dissolved to obtain a mixture A;

[0046] (2) After cooling the mixed liquid A obtained in step (1) to room temperature, add glycerin, polyethylene glycol and defoamer in the prescribed amount and stir for 70 minutes to obtain mixed liquid B;

[0047] (3) Add the organic high polycarboxylic acid metal compound in the prescribed amount to the mixed solution B obtained in step (2) while stirring, and after stirring for 25 minutes, the water-based rust inhibitor is obtained.

Abstract

The invention provides a long-acting water-based antirust agent, and aims to overcome the defects in the prior art. The long-acting water-based antirust agent comprises the following components of, byweight, 6-12% of polyethylene glycol, 1-4% of sodium benzoate, 2-6% of glycerol, 45-50% of triethanolamine borate, 2-6% of an anti-flash rust remover, 12-16% of sebacic acid, 1-3% of a defoaming agent, 1-2% of an organic high-polycarboxylate metal compound and the balance water. The water-based antirust agent can be widely applied to rust prevention during procedures of steel materials, cast iron, mechanical parts, alloy steel product assemblies and materials, and the advantages of being long in rust prevention period, convenient to clean, good in stability, not prone to decomposition at a high temperature and long in indoor storage period are achieved.

Description

Technical field [0001] The invention belongs to the field of steel rust prevention, and specifically relates to a rust inhibitor and a preparation method thereof, and more particularly to a long-acting water-based rust inhibitor and a preparation method thereof. Background technique [0002] During the storage and transportation of steel materials, cast iron, mechanical parts, and alloy steel products, if they are not subjected to anti-rust treatment, rust will occur in a short period of time, which will adversely affect the appearance and performance of the finished steel and precision parts, and the corrosion will be serious It may even cause scrap steel, unusable parts, and great economic losses. Therefore, the research of anti-rust solution plays an important role in the protection of steel materials. Most of the metal water-based rust inhibitors used in the past contain sodium nitrite. The nitrite type water-based rust inhibitor has obvious advantages such as low price, good...
