Abstract

The invention relates to the technical field of chemical engineering and provides a deruster and a preparation method thereof. The deruster is composed, by weight, of 15-25 parts of trisodium phosphate, 12-16 parts of acrylic ester copolymers, 14-18 parts of antimony trioxide, 10-20 parts of inositol hexaphosphate, 16-20 parts of acrylamide, 6-8 parts of tolyl triazole, 16-24 parts of dodecyl phenyl succinic acid, 11-17 parts of diethoxy estersil ethane, 6-12 parts of dibutyl phthalate, 8-12 parts of fluorocarbon emulsion, 6-8 parts of modified vermiculite powder and 30-40 parts of deionized water. According to the deruster, the derusting time is short, the derusting effect is good, secondary rust of metal after derusting is not liable to occur, the component source is wide, the preparation process is simple, and the deruster is suitable for being popularized in the field of chemical engineering.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of chemical industry, in particular to a rust remover and a preparation method thereof. [0003] 【Background technique】 [0004] Metal is easy to rust when placed outdoors or in the open air. Rust is a chemical reaction, which is essentially an oxidation reaction of metal. Metal rust not only affects the appearance quality, but also affects the normal progress of painting, bonding and other processes. These Rust will seriously affect the operation of subsequent processes and the quality of products. If it is not handled in time, it will lead to scrapping of materials and unnecessary economic losses. Therefore, it is necessary to remove rust from metals. Existing rust removal methods generally use chemical rust removal, mainly using strong acid solution or strong alkali solution to oxidize rust to achieve the effect of rust removal, but insufficient dosage during use will lead to unclean rust removal....
