CN103484223A - Gas-phase rust preventive oil and preparation method thereof - Google Patents

Abstract

Gas-phase rust preventive oil comprises the following components: 12-19 parts of an acid soap complex agent, 4-8 parts of a rust preventive 1, 6-10 parts of a rust preventive 2, 5-7 parts of an improver, and 60-70 parts of a complex solubilizer. The invention further discloses a preparation method of the gas-phase rust preventive oil. Aiming at the condition that complete rust preventive oil cannot be produced a large-scale closed storage tank, a dedicated gas-phase rust preventive oil is developed, and the gas-phase rust preventive oil can not only form a good rust preventive protection layer on the metal surface, but also diffuses VCI gas-phase rust preventive gas at the same time.

Description

Volatile rust preventive oil and preparation method thereof

Technical field

The present invention relates to a kind of slushing oil and preparation method thereof, be specifically related to a kind of volatile rust preventive oil and preparation method thereof.

Background technology

Corrosion is one of principal mode that fastening piece is destroyed, and to automobile, motorcycle and various vehicle, machinery, can cause very large loss.According to statistics, the annual direct economic loss caused due to metallic corrosion accounts for 2%～4% of total value of production in national economy.The method that prevents corrosion of metal is a lot; the most frequently used method is to cover various corrosion protection layers in metallic surface; also can in corrosion protection medium liquid state or gaseous state, add inhibiter, make metallic surface generate protective membrane, to completely cut off contacting of metallic surface and corrosives.

For avoiding corrosion, reducing the loss, people have adopted various methods, as adopted slushing oil.

Slushing oil is a kind of of lubricating oil, is the Oil solvent with antirust function, base oil and supplementary additive etc., consists of.Be widely used in steel, copper, aluminium, zinc-plated, indoor rust prevention during manufacture or the packing of the various metallic articles such as cadmium plating and subassembly thereof are sealed up for safekeeping antirust.But the slushing oil that rust-proof life is longer, easily produce thicker oil film, easily sticky hand after oiling on part; The slushing oil rust-proof life that oil film is thin is shorter, damp and hot not ideal with salt-fog test.

Tradition slushing oil is to form the protective layer that intercepts aqueous vapor in metallic surface; but large scale structure complex apparatus; can't use and soak the main equipment that reaches 100% comprehensive application slushing oil for this type of; or large-scale sealed storage bucket; or only can carry out the sealed storage groove equipment of oil spout operation with small filler port, have surface coverage water proof gas concurrently and imitate the Novel state Gas Xiang Fang Rust oil of unification in response to birth with Gas phase Fang Xiu Twin.Workpiece operation like that all easily causes oil film imperfect, produces antirust school fruit not good.

Conventional gas-phase slushing oil is all to add dicyclohexyl amine, strong amine gas is distributed in utilization, produce antirust oxidation resistant effect for metal, but dicyclohexyl amine there is intense stimulus to eyes, skin and respiratory tract, human body is caused harm quite large, as careless eyes directly contact, may cause permanent visual impairment, and the prolonged and repeated lower concentration contact of skin also can cause the problems such as dermatitis, so the strong European Union member countries in environmental consciousness, dicyclohexyl amine is to be regarded as unwelcome pharmaceutical chemicals.

Summary of the invention
