Description
Technical Field
The invention relates to the field of preparation of strippable plastic rust inhibitors, in particular to a solvent-based strippable plastic rust inhibitor and a preparation method thereof.
Background
The prevention of corrosion of metal parts is a major concern for manufacturing enterprises, and common corrosion prevention measures include: painting, soaking in antirust oil, anodizing, surface coating and other steps. The anodizing and surface coating processes are expensive and the subsequent treatment of waste liquid is complicated, so the method is not a common means for corrosion prevention and rust prevention. For parts painted with paint, a film layer on the surface needs to be removed, and alkali washing, organic solvent washing and physical film removal methods are generally adopted, but the method often cannot treat or damages the surface. The traditional antirust oil products are prepared by dissolving various corrosion inhibitors and film forming agents in mineral oil and then fully mixing the corrosion inhibitors and the film forming agents with refined solvents. Most of the corrosion inhibitors are petroleum sulfonate and carboxylic acids, most of the film forming agents are vaseline, beef tallow and oxidized petroleum ester metal soaps, and after the rust inhibitors are sprayed on the surfaces of parts and a solvent is volatilized, an oily mucosa can be left, and the following problems are caused:
(1) when the antirust agent is transported by sea, the temperature difference change is large, and the antirust agent is easy to desorb;
(2) the seal is rustproof, and an oil film is difficult to remove during unsealing;
(3) when the laminated steel plate is stored in a laminated mode, the abrasion and the damage to an oil film inevitably occur, and the corrosion of parts is caused.
Therefore, compared with the rust-proof products of the above types, the strippable plastic has the following advantages:
(1) the film layer is transparent and has no greasy feeling;
(2) the plastic film has certain mechanical strength, and the outer surface of the plastic film is not easy to be injured;
(3) can withstand large temperature differences;
(4) the oil seeped from the film layer separates the metal surface from the film layer, which is convenient for unsealing;
(5) the rust-proof period is longer, and can reach 5-10 years if the package is good;
the strippable plastic is prepared by adding mineral oil, plasticizer, antirust agent, stabilizer, mildew preventive and the like into plastic serving as a base material and heating or dissolving the mixture. The coating is coated on a required sample by using the methods of dipping, coating, brushing, spraying and the like, and a plastic film layer is formed after the sample is cooled or the solvent is volatilized, so that the metal can be prevented from being corroded or scratched. This plastic film can be peeled off from the substrate surface at the time of unsealing, and is therefore also called a peelable plastic. According to different production processes, the strippable plastics can be divided into: hot melt type strippable plastics and solvent type strippable plastics. The hot-melt peelable plastic is a soft solid plastic formed by heating and melting a resin, adding other auxiliary materials, and melting the mixture. The hot melt type strippable plastic is not suitable for being used on articles which cannot bear higher temperature of dip coating, and the large-scale application of the hot melt type strippable plastic in industry is limited due to stricter requirements on the formula, the material selection and the preparation of the hot melt type strippable plastic. The solvent type strippable plastic is liquid plastic formed by dissolving resin in an organic solvent and then fusing the organic solvent with other additives at normal temperature. However, the current solvent-based strippable plastic rust inhibitors do not achieve the optimal storage time and excellent mechanical strength and corrosion resistance, so the components and process of the rust inhibitor need to be optimized.
