Derusting paste with polishing effect

Abstract

The invention provides derusting paste with a polishing effect. A boron sulphate derusting agent is mixed with a thickening agent and abrasive; and the mass ratio of the boron sulphate derusting agent, to the thickening agent and to the abrasive is 100: 0.1-1: 0.3-1.2. The strong derusting paste has a fast and simple derusting function on serious rust, and also has a passivating effect and an oxidization preventing function; the derusting effect is superior to a strong acid or nitrogen and phosphorus derusting agent, the derusting paste is green and environment-friendly and has no toxic and side effects on human bodies, and the brightness of a derusted base material can reach 8 K or above.

Description

technical field

[0001] The invention relates to the technical field of rust removal, in particular to a rust removal paste with a polishing effect. Background technique

[0002] Materials such as ferrous metals and non-ferrous metals are prone to rust when placed outdoors or in the open air, which not only affects the appearance quality, but also affects the normal process of painting and bonding. Necessary economic loss.

[0003] The first generation of rust remover is a strong acid, which can chemically react with rust and metal oxides to form soluble salts, so as to achieve the purpose of rust removal. At the same time of rust removal, the acid can react with the base metal to release hydrogen. Hydrogen can generate pressure on rust and insoluble scale, which is beneficial to their peeling and reduction of high-valent iron, and accelerates the pickling process, but the traditional acid treatment method also has obvious defects: a large amount of hydrogen gas in the proce...
