Non-phosphorus water-based metal cleaner

Abstract

The invention discloses a non-phosphorus water-based metal cleaner which is prepared from raw materials, namely, isodecanol polyoxyethylene ether, 1,3-butanediol, dodecanedioic acid, petroleum barium sulfonate, water, modified siloxane defoaming agent, sylvite, fatty alcohol polyoxyethylene ether, p-tertiary butyl benzoic acid, triazine polycarboxylic acid compounds, fatty alcohol-polyoxyethylene ether, benzyl alcohol fatty alcohol polyoxyethylene ether, isoundecanol polyoxyethylene ether, butyl cellosolve, n-hexane, glycol, glycerol, fatty alcohol-polyoxyethylene ether, fatty alcohol-polyoxyethylene ether, alkyl polymers or blocked polyether, castor oil polyoxyethylene ether, succinic acid derivative, boric acid, petroleum sodium sulfonate, imidazoline, methyl triazole, polyoxyethylene ether, fatty alcohol alcoxyl compounds, triazole, ether carboxylic acid organic chelating agents and the like. The non-phosphorus water-based metal cleaner is excellent in cleaning capability, long in anti-rusting period, low in foam, long in service life and applicable to ferrous metal and non-ferrous metal processing industry.

Description

technical field [0001] The invention relates to a phosphorus-free water-based metal cleaning agent. Background technique [0002] Existing water-based metal cleaning agents, due to various reasons such as their formulations, use phosphorus-containing builders and other additives. Although they have a certain cleaning ability, the phosphorus element will cause eutrophication of the environmental water body. The discharge of waste liquid is strictly restricted, which cannot meet the requirements of the market and environmental protection. And the existing water-based metal cleaning agent, although it has certain anti-rust properties to metal materials, the anti-rust period is relatively short, generally 1-3 days, which cannot meet the requirement of not doing anti-rust treatment for a long time during cleaning between processes . Contents of the invention [0003] The object of the present invention is to provide a phosphorus-free water-based metal cleaning agent, which ha...
