Problems solved by technology

General water-based anti-rust agents have unsatisfactory anti-rust effect and short anti-rust time; while anti-rust oil has good anti-rust performance, but the cost is high and the viscosity is high, especially for sheet products (such as engine gaskets and Piston rings, etc.) are easy to stick together. When the main engine factory automatically assembles the products, they need to be separated manually, which greatly reduces production efficiency and increases production costs. It is very inconvenient

Abstract

The invention discloses a water-based environment-friendly antirust agent. The water-based environment-friendly antirust agent comprises diethylene glycol monobutyl ether, pentaerythritol tetraoleate, polyethylene glycol, gluconate, triethanolamine, molybdate, organic phosphoric acid, fluorescent granules, sodium nitrate, urotropine, a surfactant and deionized water. The raw materials in the formula do not contain benzene and nitrite, the organic volatile matter content is 0.3 to 0.5 ppm, the harmful volatile matter content is low, and human health is not influenced, so the prepared water-based environment-friendly antirust agent is environment-friendly and healthy; the water-based environment-friendly antirust agent has a good antirust effect and can resist rust at normal temperature for one year; the water-based environment-friendly antirust agent has low viscosity, the film thickness reaches 3 to 6 microns after a product is coated with the water-based environment-friendly antirust agent, and subsequent treatment is not needed, for example, a cleaning agent for cleaning again is not needed, so that the use cost can be reduced; the small amount of fluorescent granules can reflect light easily under light, so that the missed spraying or missed coating phenomenon is avoided when the water-based environment-friendly antirust agent is used; and the preparation method is simple, low in cost and suitable for large-scale production and application.

Description

technical field [0001] The invention belongs to the technical field of antirust agents and their preparation, in particular to a water-based, environment-friendly and long-acting antirust agent suitable for metals. Background technique [0002] Anti-rust agent is a super-efficient synthetic penetrating agent, which can penetrate into rust, corrosion, and oil stains to easily remove rust and corrosion on screws and bolts. Corrosion, metal protection and other properties. And it can form and store a layer of lubricating film on the surface of the component, which can inhibit the corrosion caused by moisture and many other chemical components. [0003] Most of the traditional metal water-based anti-rust agents contain sodium nitrite. Nitrite-based water-based anti-rust liquid has obvious advantages such as low price, good effect, convenient use, and easy removal, so it is widely used. Nitrates can be converted into carcinogens and their use and discharge are strictly limited....
