Metal cleaner used for coating production line and preparation method thereof

Abstract

The invention relates to a metal cleaner used for a coating production line and a preparation method thereof. The metal cleaner consists of the following components in percentage by weight: 10 to 14 percent of triethanolamine, 2 to 4 percent of neodecanoic acid, 6 to 12 percent of dodecyl polyglycoside, 10 to 15 percent of heterogeneous XI alcohol ethoxylate, 10 to 15 percent of block polyether of ethylene oxide and propylene epoxide, 20 to 25 percent of caster oil diethanolamide-based non-ionic surfactant, 0.1 to 0.2 percent of styrene triazole and the balance of water. The appearance of the metal cleaner is transparent light yellow liquid; and when the metal cleaner is diluted at the concentration of 5 percent with water, the pH value is between 8.2 and 8.8. The metal cleaner is particularly suitable to be used for cleaning a metal workpiece on a coating production line before coating, meets the requirement on environmental protection, and has the characteristics of high cleaning performance, long service life, low foam, high compatibility with anti-rust oil and anti-rust paint, low influence on rubber plastic parts, high cost performance and capacity of replacing similar imported cleaner products.

Description

technical field [0001] The invention relates to a metal cleaning agent used in a coating production line and a preparation method thereof, which is particularly suitable for cleaning metal parts of the coating production line before coating. Background technique [0002] Recently, with the rapid development of the national economy, more and more metal products have begun to be painted on the assembly line. When coating metal parts on the assembly line, in order to ensure the quality of the coating, the metal parts need to be cleaned before coating. The metal cleaning agent used in the coating production line not only requires good cleaning performance, but also requires no corrosion of ferrous metals and non-ferrous metals and has a certain anti-rust property, especially to be combined with anti-rust oil or anti-rust oil used in the subsequent coating process. Rust paint is compatible and has no harm to people and the environment. However, the current domestic cleaning age...

Problems solved by technology

Among foreign products, although the metal cleaning agent of German Henkel Company can better meet the requirements of the coating production line, its cost performance is greatly reduced due to its high price.
