Example Embodiment

[0008] Example 1, a long-acting water-based anti-rust agent, is composed of 500-800 parts by weight of industrial alcohol, 15-25 parts of HLD-1 anti-rust dispersant, 100-140 parts of base oil, 1.5-2 parts of 2.6 -Di-tert-butyl p-cresol, 15-25 parts of barium dinonylnaphthalene sulfonate, 40-70 parts of water, 15-25 parts of sorbitol monooleate, HLD-1 anti-rust dispersant is composed of Lanolin magnesium soap, N-oleamic acid ammonium salt, and NP-9 are composed in a weight ratio of 3:2:1. The above materials are added to a 2T reactor to dissolve in batches, fully stirred, and heated to 60℃2 After hours, stop heating after the various raw materials are fully dissolved, and then add deionized water. When the temperature drops below 30°C, release the finished product.

[0009] This embodiment uses 500kg of industrial alcohol, 25kg of HLD-1 anti-rust dispersant, 100kg of base oil, 2kg of 2.6-di-tert-butyl p-cresol, 15kg of barium dinonylnaphthalenesulfonate, 70kg of water, 15kg of sor...

Example Embodiment

[0010] Example 2, a long-acting water-based anti-rust agent, using 800 kg of industrial alcohol, 15 kg of HLD-1 anti-rust dispersant, 140 kg of base oil, 1.5 antioxidants, 25 kg of barium dinonyl naphthalene sulfonate, 40 kg of water, The composition of 25kg sorbitol monooleate is completely the same as in Example 1.

Example Embodiment

[0011] Example 3, a long-acting water-based anti-rust agent, using 650 kg of industrial alcohol, 20 kg of HLD-1 anti-rust dispersant, 120 kg of base oil, 1.8 kg of antioxidants, 20 kg of barium dinonyl naphthalene sulfonate, 55 kg of water , 20kg sorbitol monooleate composition, and the other is exactly the same as in Example 1.

[0012] The long-acting water-based rust inhibitor of the present invention is suitable for long-term rust prevention of cast iron, cast steel and powder metallurgy parts, especially suitable for rust prevention of shipping and storage metal parts, and also suitable for electronic precision instruments, radars, gears, and automatics. Long-term rust prevention of weapons, hardware tools, machinery accessories and other products.

Abstract

The invention discloses a long-acting water-based rust inhibitor. The long-acting water-based rust inhibitor is prepared from, by weight, 500-800 parts of industrial alcohol, 15-25 parts of an HLD-1 rust-inhibition dispersing agent, 100-140 parts of base oil, 1.5-2 parts of 2,6-di-tert-butyl-4-methyl phenol, 15-25 parts of barium dinonyl naphthalene sulfonate, 40-70 parts of water and 15-25 partsof sorbitan monooleate. The materials are added into a 2T reaction kettle to be dissolved and stirred, heating is conducted to 60 DEG C and stopped 2 hours later, then deionized water is added, and when the temperature is reduced to 30 DEG C or below, a finished product can be discharged. The long-acting water-based rust inhibitor has the advantages that the problem of damage caused by aromatic hydrocarbon gas in a solvent to the human body is thoroughly solved, the flammable and explosive danger and the damage to the environment are reduced, and the requirement that special parts must be freeof oil is met.

Description

technical field [0001] The invention belongs to the technical field of antirust agents, and in particular relates to a long-acting water-based antirust agent mainly for long-term sealing and packaging of ferrous metal casting parts and the like. Background technique [0002] Water-based anti-rust is a major problem that has plagued domestic and foreign manufacturing industries for many years. The anti-rust period of most water-based anti-rust agents is about three months, which cannot meet the anti-rust requirements of products and is extremely alkaline (based on Sodium oxide and sodium hydroxide are the main materials to increase alkalinity), pollute the environment, and are difficult to handle and discharge. Most products also use toxic and harmful sodium nitrite chemical components as anti-rust agents. The surface of the parts after anti-rust treatment Dull, and the residual surface is prone to white and yellow, which seriously affects the product quality of the machine p...
