The invention relates to novel antirust oil and a preparation method thereof, in particular to novel antirust oil capable of prolonging salt spray time and improving antirust performance and a preparation method thereof.
Background
The rust problem is distributed in various industries, and two protective measures, namely permanent and temporary, can be adopted according to different rust prevention requirements. Permanent rust prevention is mostly performed by using methods such as paint, coating or electroplating, and temporary rust prevention is mostly performed by using rust preventive oil for protection. The rust preventive oil is prepared by taking mineral oil as base oil and adding a proper amount of rust preventive. The rust preventive oil is coated on the surface of metal to form a very thin adhesive film to prevent rust, and is mainly used for indoor short-term sealing and rust prevention of metal materials and products thereof.
The antirust agent generates physical adsorption on the metal surface due to electrostatic attraction between polar dipoles and the metal surface, and some antirust agent polar groups also generate chemical reaction with the metal surface to form chemical adsorption. Most of traditional anti-rust oil is pure mineral oil as base oil, the polarity is poor, the adsorption capacity with the metal surface is not strong, and the anti-rust oil cannot be well isolated from substances such as water in the air, so the anti-humidity performance is poor, and the salt spray resistance test is not performed. According to the invention, PAG synthetic oil is additionally added, and the excellent polarity of PAG synthetic oil compared with mineral oil is utilized, so that the PAG synthetic oil is preferentially combined with the antirust agent to be adsorbed on the metal surface, and the adsorption layers play a role in preventing oxygen, moisture and acidic substances in the air from corroding the metal surface, thereby achieving an antirust effect, wherein the stronger the polarity of the antirust agent is, the firmer the adsorption is, and the better the antirust effect is.
At present, the production current situation of many users is that the product needs long time for transportation, storage, use and sealing after leaving factory, and the ambient climate conditions and the like, and a more durable salt spray resistance test is needed to achieve a longer storage time.
