Abstract

The invention discloses an environment-friendly type water-based anti-rusting agent which consists of the following components in percentage by weight: 15-25% of organic amine, 40-55% of pure water, 20%-25% of polybasicester, 2%-5% of diglycolamine, 2%-5% of borate, 0.1%-0.5% of an efficient de-foaming agent, 0.05%-0.1% of an environment-friendly penetrating agent and 0.02%-0.5% of a preservative. The invention further provides a preparation method of the environment-friendly type water-based anti-rusting agent. According to the environment-friendly type water-based anti-rusting agent, mineral oil is not used as a medium, so that the petroleum resources are saved. Meanwhile, the environment-friendly type water-based anti-rusting agent is good in anti-rusting performance, and a cast iron material has an anti-rusting period of 9-11 months under humid and temperature environments.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an environment-friendly water-based antirust agent for metals, in particular to an environment-friendly water-based antirust agent and a preparation method thereof. Background technique [0002] In the field of metal machining, since the metal workpiece needs to go through multiple processing processes from the blank to the finished product, the original reserve parts cannot be processed in the next process in a short period of time, so they need to be stored in the warehouse. Metals will be more or less corroded due to different surrounding environments. Traditional anti-rust oils use different lubricating oils as the medium. The oil-soluble barium salt used in anti-rust oil is an organic compound. Although it is not poisonous in itself, it will decompose into soluble barium salt when scattered in the natural environment, forming There are barium-containing toxic substances, an...
