Water solubility antirust agent and preparation method thereof

Abstract

The invention discloses a water solubility antirust agent and a preparation method thereof. The water solubility antirust agent is prepared by the following steps that phytate, gluconic acid, phosphorous acid calcium hydrogen, polyaspartic acid, phenylalanine, sodium tetraborate, lignin sulfonate, sodium citrate and distilled water are mixed and stirred for 20-30 minutes under the rotating speed of 200-400 r / min, heated to 75-80 DEG C, stirred for 10-30 minutes and reduced to 50-60 DEG C after hydroxyl silicone oil emulsion is added, stirred for 20-40 minutes under the rotating speed of 300-500 r / min and cooled to indoor temperature after sodium silicate, polyving akohol and diethylenetriamine are added, and the water solubility antirust agent is obtained after filtering is conducted. The water solubility antirust agent has the advantages of being excellent in antirust performance, good in corrosion resistance, great in anticorrosion effect and good in antirust performance.

Description

technical field [0001] The invention relates to the field of fine chemical materials, in particular to a water-soluble antirust agent and a preparation method thereof. Background technique [0002] Metal corrosion is very common in the process of storage and use. It is a serious problem that people must face. It not only affects the appearance and performance of metal products, but also directly affects their service life, causing huge losses to the national economy. From a perspective, it is still a waste of resources. It may even hinder the development of new technologies. According to statistics, the annual economic loss caused by metal corrosion in the world reaches 700 billion U.S. dollars, which is about 6 times the sum of natural disaster losses such as earthquakes, fires, and typhoons. Therefore, the research on rust inhibitors is of great significance to the protection of metal materials. From the point of view of saving resources and protecting the environment, th...

Problems solved by technology

From the point of view of saving resources and protecting the environment, the use of water-soluble antirust agents instead of oil-soluble antirust agents has many advantages, especially for inter-process rust prevention, because oil-soluble antirust agents are used during heat treatment. It emits unpleasant oil fumes, pollutes the environment, affects people's health, is easily contaminated with dust and affects its anti-rust performance, and at the same time has the danger of causing fire

But on the other hand, most of the general water-soluble corrosion inhibitors contain nitrite, phosphate or chromate. Such rust inhibitors are highly toxic, and the discharge of wastewater is likely to cause eutrophication of the water body. The use and discharge are strictly restricted.
