Environment-friendly long-life emulsified antirust agent and preparation method thereof

Abstract

The invention discloses an environment-friendly long-life emulsified antirust agent and a preparation method of the environment-friendly long-life emulsified antirust agent. The antirust agent is prepared from the following components: 40-50% of white oil with the ISO viscosity grade lower than 46#, 20-30% of diglycolamide oleate borate, 5-10% of sorbitan fatty acid ester, 5-10% of sodium dodecyl benzene sulfonate, 3-5% of N-oleoylsarcosine octadecylamine, 3-5% of zinc naphthenate, 2-3% of nonylphenol polyoxyethylene ether, 0.5-1% of benzotriazole, and 5-10% of water. The preparation method is as follows: the benzotriazole and the sorbitan fatty acid ester are weighed and fully stirred to be transparent, then, the white oil, the diglycolamide oleate borate, the N-oleoylsarcosine octadecylamine, the zinc naphthenate, the nonylphenol polyoxyethylene ether and the sodium dodecyl benzene sulfonate premixed with water are added sequentially, and the mixture is fully stirred at the temperature of 25-40 DEG C for 30-60 minutes to complete transparency. The antirust agent provided by the invention has a good antirust property, and still has an excellent antirust property after being added with water with the weight of 4-20 times that of the antirust agent, meanwhile, the antirust agent is convenient to clean, the energy is saved and the consumption is reduced, and the damage to the environment and workers is reduced.

Description

technical field [0001] The invention belongs to the technical field of metal antirust, and in particular relates to an environment-friendly long-life emulsified antirust agent and a preparation method thereof. Background technique [0002] Traditional medium- and long-term rust prevention of metal generally uses anti-rust oil for brushing treatment to prevent rust. The amount of anti-rust oil used is large and the cost is high. The parts to be processed in the subsequent process are difficult to clean after anti-rust oil is used. [0003] At present, there are still some water-based anti-rust agents such as borates, phosphates, and carboxylates on the market. Due to the short anti-rust time, they can only be used for short-term anti-rust. Sodium nitrite is also used as a water-based antirust agent. Although it has a certain antirust effect, sodium nitrite is carcinogenic and is banned in many countries. Contents of the invention [0004] The purpose of the present invent...
