Environment-friendly metal rust-removing spray liquid and preparation method thereof

Abstract

The invention discloses an environment-friendly metal rust-removing spray liquid and a preparation method thereof, and relates to the technical field of chemical raw materials. The spray liquid is prepared by mixing and processing the following components according to a reasonable formula: organic acid, dextrin, sodium phosphate, deionized water, sodium tripolyphosphate, sodium benzoate, an activator, platinum trioxide, and isopropanol. The preparation method has the advantages of simpleness, convenience, environment-friendliness, easily-available raw materials, little equipment investment, and convenient operation. The prepared environment-friendly metal rust-removing spray liquid has the advantages of good using effect, strong rust removing performance, no side or toxic effect, and safe and reliable application.

Description

technical field [0001] The invention relates to the technical field of chemical raw materials, in particular to an environment-friendly metal derusting spray liquid and a preparation method thereof. Background technique [0002] Rust is a chemical reaction. When iron is left for a long time, it will rust. Tin box will rust for a long time, iron is easy to rust, in addition to its vivid chemical properties, but also has a lot to do with the external conditions. Moisture is one of the substances that make iron easy to rust. However, only water does not make iron rust, only when the oxygen in the air is dissolved in water, the oxygen reacts with iron in the environment with water, and iron oxide will be produced, which is rust. Iron rust is a kind of brownish-red material, it is not so hard as iron, it is easy to fall off, after a piece of iron gets rusty completely, its volume can expand by 8 times. If the rust is not removed, the spongy rust is especially easy to absorb wa...

AI Technical Summary

Problems solved by technology

If the rust is not removed, the spongy rust is especially easy to absorb water, and the iron will rust faster. When the iron rusts, it will be heavier, about 3 to 5 times its original weight. After the metal gets rusted, Its texture and aesthetics will be affected accordingly. However, there are a variety of metal rust removal products on the market, but none of them can really play a significant role, and there will be corresponding toxicity, which will affect human health.
