CN103484223B - 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 can cause very large loss to automobile, motorcycle and various vehicle, machinery.According to statistics, the direct economic loss caused due to metallic corrosion every year accounts for 2% ~ 4% of total value of production in national economy.Prevent the method for corrosion of metal a lot; the most frequently used method covers various corrosion protection layer; also can liquid state or gaseous state corrosion protection medium in add inhibiter, make metallic surface generate protective membrane, with the contact of isolated metallic surface and corrosives.

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

Slushing oil is the one of lubricating oil, is the Oil solvent with antirust function, is made up of base oil and supplementary additive etc.Be widely used in steel, copper, aluminium, zinc-plated, indoor rust prevention during manufacture or the packaging of the various metallic article such as cadmium plating and subassembly thereof are sealed up for safekeeping antirust.But the slushing oil that rust-proof life is longer, part easily produces thicker oil film after oiling, easily sticky hand; 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 forms the protective layer intercepting aqueous vapor; but large scale structure complex apparatus; the main equipment soaking and reach 100% comprehensive application slushing oil cannot be used for this type of; or large-scale sealed storage bucket; or the sealed storage groove equipment of oil spout operation only can be carried out with small filler port, have surface coverage water proof gas and Gas phase Fang Xiu Twin concurrently and imitate the Novel state Gas Xiang Fang Rust oil unified in response to birth.Workpiece operation like this all easily causes oil film imperfect, produces antirust school fruit not good.

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