Problems solved by technology

[0003] 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
[0004] On the other hand, although the existing water-based metal cleaning agents have certain antirust properties on metal materials, the antirust period is relatively short, generally 1-3 days, which cannot satisfy the cleaning between processes and does not prevent rust for a long time. processing request

Abstract

The invention discloses a phosphorus-free cleaning agent. The phosphorus-free cleaning agent comprises the following components in parts by weight: 12-18 parts of sodium citrate; 10-15 parts of a surfactant; 4-7 parts of a chelating agent; 10-15 parts of 2,4-di-(p-aminobenzoic acid)-6-diethylamino-1,3,5-triazine, 1-3 parts of a corrosion inhibitor; 5-8 parts of a penetrating agent; 2-4 parts of propylene glycol monomethyl ether; 0.8-1.4 parts of a defoaming agent; and 2-20 parts of water. The phosphorus-free cleaning agent disclosed by the invention has the advantages of excellent cleaning capacity, a long antirust period, good stability, long service life, no volatilization and no irritation.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a phosphorus-free cleaning agent. Background technique [0002] Water-based metal cleaning agents are widely used in various industries such as machinery manufacturing and repair, automobile manufacturing and repair, transportation vehicle cleaning, equipment maintenance, electroplating and painting, etc. Water-based metal cleaning agents have become an indispensable process in many industries. quality control process. [0003] 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. [0004] On the other hand, although ...
