Problems solved by technology

However, if pure mineral oil is used as the base oil for anti-rust grease, many additives are insoluble or have low solubility, and the oil film strength is thin, which causes great difficulties for metal anti-rust. However, pure synthetic high-grade oil is used as the base oil. However, it faces many problems such as high cost and waste of resources.

Embodiment 1

[0021] Embodiment 1 biodiesel is used for producing L-F 20-1 Sealed anti-rust oil

[0022] Pump 25 parts by weight of paraffin-based 32# base oil and 44.5 parts by weight of biodiesel into the vacuum reactor, stir, self-circulate and heat up to 75 ° C; sequentially pump the following additives in parts by weight: ① methyl silicone oil: 0.01 Part ② Benzotriazole: 0.01 part ③ 2,6 di-tert-butyl-p-cresol: 0.48 part ④ Zinc naphthenate: 5 parts ⑤ Alkenyl succinate: 2 parts ⑥ Sorbitan monooleate (Emulsifier S-80): 2 parts ⑦ Oxidized petroleum grease barium soap: 4 parts ⑧ Barium dinonylnaphthalene sulfonate: 5 parts ⑨ Barium petroleum sulfonate: 10 parts Finally, fully stir and circulate to mix; keep the temperature of the mixed oil at 75°C, turn on the vacuum pump, and keep the vacuum at -0.096Mpa. After reacting for 0.5 hours, the sampling and analysis are qualified, and the finished product is obtained by metering, filtering and filling.

Abstract

The invention discloses an application of biodiesel in preparation of biodegradable rust preventing oil. According to the biodegradable rust preventing oil prepared by using biodiesel as the raw material, tests of product physical and chemical indexes and practical applications by equipments and workpieces in actual working conditions prove that the biodegradable rust preventing oil is comparable or even surpasses the traditional mineral-oil-based rust preventing oil in performances.

Description

technical field [0001] The invention belongs to the production field of metal anti-rust oil, in particular, the invention relates to the application of biodiesel for preparing biodegradable anti-rust oil. Background technique [0002] Corrosion problems can be found in all walks of life. Most of the metal materials and mechanical equipment are mainly iron, and cast iron, carbon steel and low alloy steel in iron metal are particularly prone to rust. Non-ferrous metals such as copper and magnesium are also easily corroded and discolored. Rust on the surface will greatly damage the performance and commodity value of metal products and mechanical equipment, and even cause major failures and make the equipment scrapped. According to statistics, about 1 / 3 of the metals smelted in the world are scrapped in industry due to rust. Of course, 2 / 3 of them can be regenerated by returning to the furnace, but more than 10% are inevitably lost due to rust. This is a direct loss, while i...
