Embodiment Construction

[0030] Metalworking fluids such as metal cutting fluids, grinding fluids, and cleaning agents have similar requirements for water-based antirust agents. Therefore, the antirust effect of 45 steel and chrome steel is tested on the spot when using this antirust agent alone or when it is added to the cleaning agent. Experiment; the advantages of this antirust agent are demonstrated by comparing with the product halox 900 of the American halox company in the residual test, salt spray test and indoor coupon test.

[0031] The water-based cleaning agent is formulated as fatty alcohol polyoxyethylene ether 15WT15%, builder 10%. In the field experiment, the amount of antirust agent added to the cleaning agent was 8%. After the antirust agent is added to the cleaning agent, it needs to be fully stirred until it is uniform.

Abstract

The invention discloses a novel water-based rust inhibitor and a preparation method and a use method thereof, belonging to the technical field of metal material corrosion prevention. The rust inhibitor can substitute for antirust oil and grease to prevent rust in the inter-process of metal processing and store and prevent rust of finished products, and also can be used as antirust additive of metal working fluid such as metal cutting fluid, grinding fluid, washing agent and the like, so as to reduce the antirust cost in metal processing and storage and conveying processes. The rust inhibitor is obtained by adopting the following technical scheme: combining 5-15wt% of organic zinc chelate, 5-10wt% of amide-type surfactant and 1-5wt% of water-soluble antirust additive.

Description

technical field [0001] The invention relates to a water-based antirust agent used for antirust between metal processing processes and for sealing and antirust of finished products, and as an antirust additive for metalworking fluids such as metal cutting fluids, grinding fluids, and cleaning agents. The invention belongs to the technical field of anticorrosion of metal materials. Background technique [0002] Metals in the atmosphere will react chemically or electrochemically with oxygen, water and other impurities under certain conditions to cause metal corrosion. Especially for metal materials in the metal processing process, due to the high surface activity, the workpiece is prone to rust due to humid air, hand sweat, and contact with harmful gases in the atmosphere during processing, handling, and inspection, resulting in Processing workpieces are scrapped or reworked. In order to prevent metal workpieces from rusting during storage, antirust treatment must be carried ...
