Abstract

The invention discloses environment-friendly water-based antirust liquid as well as a preparation method and application thereof, and belongs to the field of water-based antirust liquid. The environment-friendly water-based antirust liquid comprises the following preparation raw materials in percentage by mass: 5-15% of an antirust agent, 5-15% of special amine, 1-5% of a water-based film-forming agent, 0.5-5% of a penetrant, 0.01-1% of a defoaming agent and the balance of water. The environment-friendly water-based antirust liquid has the characteristics of excellent salt spray corrosion resistance, humidity and heat resistance and low foam, is free of environmental pollution substances such as heavy metal residues and the like, and meets the requirements of environmental protection laws and regulations. The antirust liquid can be directly applied to protection of materials such as metal materials, instrument and equipment parts and the like. The preparation method provided by the invention is simple and convenient to operate, does not need a special process and can realize industrial production.

Description

technical field [0001] The invention belongs to the field of water-based antirust liquid, and in particular relates to an environment-friendly water-based antirust liquid and its preparation method and application. Background technique [0002] Metal materials are subjected to chemical or electrochemical reactions under the influence of corrosive media such as oxygen and water in the air to corrode the metal. According to statistics, the annual steel corrosion is 10% to 20% of the steel production in that year. Metal corrosion not only affects the appearance of metal materials and the accuracy of equipment, but can even directly affect the service life of equipment, causing a lot of economic losses. Metal protection plays an important role in the manufacture of production equipment, chemicals, auto parts, and military industries. [0003] At present, the domestic existing water-based anti-rust liquid technology mainly uses nitrite, phosphate, benzotriazole, boric acid, seb...
