Environment-friendly waterborne antirust agent and preparation method thereof

Abstract

The invention discloses an environment-friendly waterborne antirust agent. The environment-friendly waterborne antirust agent is prepared by proportioning the following components in parts by weight:7 parts of rosin polymer, 5 parts of heterocyclic antirust agent, 20 parts of triethanolamine borate, 12 parts of ethanolamine (MEA), 0.3 part of ethylenediamine tetraacetic acid disodium (EDTA disodium), 0.2 part of polyethylene glycol 400 and 55.5 parts of pure water. The antirust agent made of the rosin polymer has good post-cleaning performance and better antirust capability than conventionalwaterborne antirust agent, has very high absorptivity and spreadability on the surface of steel and iron, and has performance similar to that of oily products, and the raw materials for preparing theantirust agent are easily available and low in price; and meanwhile, the environment-friendly waterborne antirust agent does not contain organic solvents such as benzene, toluene, xylene, formaldehydeand the like and heavy metals, is incombustible and non-explosive, does not pollute the environment, and belongs to an environment-friendly product.

Description

technical field [0001] The invention relates to the technical field of antirust liquid, in particular to an environment-friendly water-based antirust agent and a preparation method thereof. Background technique [0002] Anti-rust oil is generally used for medium and long-term anti-rust of traditional steel products, but anti-rust oil generally contains heavy metal ions such as barium and chromium. High, from the perspective of energy saving and environmental protection, it is also an extremely unenvironmental behavior, especially for some parts that need to be processed later, it is difficult to clean after using anti-rust oil to prevent rust. Contents of the invention [0003] The purpose of the present invention is to provide an environmentally friendly water-based anti-rust agent to solve the problems of short time for using anti-rust oil and cleaning after use when metal products are rust-proof, and at the same time solve the problem that other water-based anti-rust ag...
