Problems solved by technology

According to statistics, the annual direct economic loss caused by metal corrosion accounts for about 2% to 4% of the total output value of the national economy. Material is the most common method, and there are many problems in today's anti-rust oil, such as corrosion resistance, durability, adhesion, poor, prone to hardening, falling off, cracking, so it is necessary to continuously improve the anti-rust oil Comprehensive quality, to achieve better rust and corrosion inhibition effect

Embodiment 1

[0023] A salt water resistant antirust oil for ships is characterized in that it is composed of the following raw materials in parts by weight (kg):

[0024] Kerosene 80, trisodium nitrilotriacetate 0.6, calcium palmitate 1, calcium petroleum sulfonate 10, hydroxyethylidene diphosphate 2, alkylated diphenylamine 3, bisphenyltriazole alcohol 2, acrylic acid 3, antioxidant 168 0.8 , 1-hydroxybenzotriazole 1, potassium dichromate 0.3, phthalate 2, polyisocyanate 1, rare earth anti-rust hydraulic oil 20;

[0025] Described rare earth antirust hydraulic oil is made up of the raw material of following weight part:

[0026] N-vinyl pyrrolidone 3, methyl nylon acid 2, Span80 0.7, dodecenyl succinic acid 16, hydraulic oil 110, triallyl isocyanurate 0.5, deionized water 70, potassium persulfate 0.6, Sodium hydroxide 5, cerium nitrate 2;

[0027] Mix N-vinylpyrrolidone and methyl nylonate, stir and mix at 60°C for 10 minutes to obtain esterified alkanone;

Abstract

The invention discloses saline-resistant rust-preventative oil for ships. The saline-resistant rust-preventative oil for ships is composed of the following raw materials in parts by weight: 60-80 parts of kerosene, 0.6-1 part of nitrilotriacetic acid trisodium salt, 1-2 parts of calcium palmitate, 8-10 parts of calcium petroleum sulfonate, 1-2 parts of hydroxyethylidene diphosphonic acid, 1-3 parts of alkylated diphenylamine, 2-3 parts of bitertanol, 2-3 parts of acrylic acid, 0.8-1 part of antioxidant 168, 1-2 parts of 1-hydroxybenzotriazole, 0.3-1 part of potassium dichromate, 2-4 parts of phthalate, 1-3 parts of polyisocyanate and 14-20 parts of rare-earth rust-preventative hydraulic oil. The rare-earth rust-preventative hydraulic oil is added to the rust-preventative oil disclosed by the invention; menthanone dispersing liquid is capable of improving flowability and improving reactivity, and the added rare-earth ions are capable of generating insoluble complexes with the OH<-> generated during an oxygen absorption corrosion process on the surface of a metal base material, slowing down the electrode reaction of the corrosion and acting a great slow-release effect.

Description

[0001] technical field [0002] The invention mainly relates to the field of lubricating oil, in particular to a salt water resistant antirust oil for ships. Background technique [0003] During the storage, transportation and use of metals, due to the influence of water vapor, oxygen, acid, alkali, salt and carbide in the ambient atmosphere, physical and chemical changes will occur under certain temperature, humidity and time extension conditions. rust due to change. The corrosion of metal will cause the loss of metal and the decline and loss of the function of metal parts. Metal corrosion is caused by the oxidation reaction of metal in contact with moist air or electrolyte solution. Corrosion is one of the main forms of damage to fasteners, which will cause great losses to automobiles, motorcycles, various vehicles and machinery. . According to statistics, the annual direct economic loss caused by metal corrosion accounts for about 2% to 4% of the total output value o...
