Problems solved by technology

[0004] At present, due to the increasing attention to environmental protection issues, traditional organic antirust agents are gradually being eliminated. In the prior art, there are water-based antirust agents with water as the base, but most of the water-based antirust agents have poor antirust effects, and the antirust It can only be used for short-term rust prevention between processes; moreover, water-based rust inhibitors usually contain sodium nitrite which is a pollutant

Abstract

The invention belongs to the technical field of antirust agents, and particularly discloses an antirust agent and a preparation method thereof. The antirust agent comprises organic alkali, a surfactant, a curing agent, silicate, an antirust agent body, water and the like. The antirust agent is stable in system, and is used for preventing the surface of a metal product from being rusted, a firm glass film can be formed on the surface of an object, and the antirust agent resists high temperature and friction, and is unlikely to crack and damage, and the antirust effect is remarkable; and the preparation method of the antirust agent is simple and practicable, the cost is low, and the antirust agent is easily popularized and used.

Description

technical field [0001] The invention belongs to the technical field of antirust agents, and in particular relates to an antirust agent and a preparation method thereof. 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] Antirust agent is a kind of surfactant that can make liquid quickly and evenly penetrate into a certain solid, and has a wide range of uses in the printing and dyeing industry. Superrun penetrating agent is formulated with active penetrating aids, lubricants and rust removers. It has multiple functions such as rust loosening, anti-corrosion, moisture-proof, cleaning, lubri...
