Problems solved by technology

However, due to the fact that the existing soft film antirust oil products tend to focus on certain aspects of performance, the oil film is thin, easy to flow or dry and brittle, and the comprehensive performance is not good, and the antirust effect is poor when the use environment is relatively complicated or harsh.
Chinese patent CN102031189A discloses a soft film antirust oil, which mainly consists of kerosene, machine oil, zinc naphthenate, barium dinonylnaphthalenesulfonate and other antirust agents. The oil film is thin, the strength is low, and the dropping point is low. It is easy to be lost under the action of light, heat or rain. Although the antirust performance is good, it can only be used indoors in a natural environment without rain or light; Chinese patent CN101768499A discloses a grease-type antirust with gas phase antirust function. Rust oil, due to the addition of phenolic resin lipid film modifier and octadecylamine, benzotriazole tributylamine vapor phase anti-rust agent in the formula, although the anti-rust oil film has the ability to resist the sun and rain, and has a gas-phase anti-rust function, But because there is no self-healing function, it cannot resist damage
In addition, Chinese patent CN102719184A discloses a self-healing anti-corrosion coating, which is made by adding polyurethane microcapsules to a coating composed of hydroxyacrylic resin, pigments, corrosion-inhibiting pigments, organic solvents, etc., and the coating surface treatment requirements are high. The coating film is difficult to remove, it is inconvenient to use, and the surface treatment will destroy the original shape of the metal surface, which greatly limits its scope of use, and is not suitable for use as an anti-rust soft film

Abstract

The invention discloses a rust-proof soft film composition and a preparation method thereof, belonging to the technical field of metal protection and particularly relating to a metal rust preventing technology. The rust-proof soft film composition disclosed by the invention comprises the following components in a formula in percentage by mass: 40-70 of film forming agent, 2-10 of corrosion and rust inhibitor, 1-5 of vapor phase inhibitor, 4-10 of microcapsule antirust agent, 0-10 of pigment, 1-3 of rheological agent, 0.2-1.0 of defoaming agent and 10-25 of solvent. The rust-proof soft film composition disclosed by the invention has an excellent rust-proof effect and an excellent self-repairing function; rust-proof gas volatilized by the film can meet the rust-proof requirements of inner and outer surfaces of workpieces with complex structures such as inner metal cavities, inner walls of pipelines, grooves and the like; when the rust-proof soft film is destroyed in a use process, a rust-proof core with an excellent self-repairing function of the microcapsule antirust agent can be automatically repaired, so that the condition that the rust-proof film is invalid in advance because of being destroyed is avoided, and the protection time of a protective film is prolonged; and the rust-proof soft film composition can comprehensively meet the requirement for metal rust-proof protection under severe environments such as outdoor sun and rain, sand-dust and the like.
