Long-acting water-based metal rust preventing agent

Abstract

The invention discloses a long-acting water-based metal rust preventing agent. The long-acting water-based metal rust preventing agent is prepared from, by weight, 2-10 parts of pentaerythritol tetraoleate, 5-10 parts of propylene glycol, 3-10 parts of petroleum-resin-modified paraffin emulsion, 1-2 parts of potassium oleate, 2-4 parts of sodium citrate, 0.5-1 part of lignin sulfonate, 2-6 parts of gas-phase titanium dioxide, 1-3 parts of sodium cocoate, 1-2 parts of polyvinylpyrrolidone, 1-2 parts of a modifying agent, 1-2 parts of other auxiliaries and 30-50 parts of water. Accordingly, an efficient long-acting environment-friendly water-based metal rust preventing agent product is obtained through the reasonable raw material proportion, the long-acting water-based metal rust preventing agent is suitable for rust preventing of cast iron, steel materials and multiple kinds of alloy steel, and the rust preventing cost in the metal processing, storing and transporting process is reduced; a film can be formed on the surface of metal while the long-acting water-based metal rust preventing agent is slowly released to prevent rust, therefore, the rust preventing time is prolonged, and decomposition and deterioration of metal processing liquid are inhibited; the long-acting water-based metal rust preventing agent is safe to use, environmentally friendly, simple in preparation method, low in cost and suitable for massive production.

Description

technical field [0001] The invention relates to an antirust agent, in particular to a long-acting water-based metal antirust agent. Background technique [0002] In the process of production, processing and transportation of metal processing parts, it is easy to rust due to electrochemical corrosion on the metal surface after contact with oxygen, moisture or other corrosive media in the air, which requires the use of anti-rust products on the metal surface A film is formed on the surface to prevent oxygen and water from acting on the metal surface to form a mixture of oxides and hydroxides, thereby preventing metal corrosion. The anti-rust agent is such a product. Specifically, the anti-rust agent is a highly efficient synthetic penetrating agent, which can penetrate into rust, oil stains, and corrosion, so as to easily remove the rust and corrosion on metal objects. , has the properties of resisting corrosion, penetrating rust, loosening and lubricating, protecting metal, ...

Problems solved by technology

Most of the existing antirust products are antirust oils, which often have a greater poisonous effect on the environment due to the addition of oil-soluble antirust agents; the antirust agents in the prior art can be used in water, and compared with antirust oils There is no oily feeling on the surface, and it is a safe and environmentally friendly anti-rust product, but its anti-rust time is shorter than that of anti-rust oil, and its resistance to salt corrosion and water is poor, and the anti-rust cycle is short. In the case of insufficient effect, it is necessary to frequently apply anti-rust agent, and the anti-rust efficiency is low
