Non-phosphorus environment-friendly water-based degreasing agent and manufacturing method thereof

Abstract

The invention discloses a non-phosphorus environment-friendly water-based degreasing agent with good degreasing effect, easy cleaning and capability of meeting the requirements of back end of line process and a manufacturing method thereof, and the degreasing agent is water solution formed by mixing an A agent with a B agent, wherein the concentration of the A agent is 3-5%, and the concentrationof the B agent is 1-3%; the A agent comprises the following raw materials by weight percent: 2-4% of sodium carbonate, 2-4% of sodium silicate pentahydrate, 2-4% of sodium citrate, 3-7% of sodium nitrite, 0.5-1% of nekal, 3-5% of triethanolamine, 0.1-0.3% of defoaming agent and the balance of tap water; and the B agent comprises the following raw materials by weight percent: 0.5-1.8% of potassiumhydroxide, 4-6% of activating agent QYL-20, 1.5-3% of activating agent AEO-9, 0.5-1% of penetrating agent JFC, 0.8-1.5% of turkey red oil, 0.4-0.8% of defoaming agent and the balance of the tap water.

Description

technical field [0001] The invention relates to a metal workpiece surface degreasing agent and a manufacturing method thereof, in particular to a phosphorus-free and environment-friendly water-based degreasing agent which has good degreasing effect, is easy to clean and can meet the requirements of subsequent processes, and a manufacturing method thereof. Background technique [0002] During the manufacture and use of metal workpieces, due to mechanical processing, rust prevention, loading, storage and transportation, etc., the surface of metal workpieces is often in contact with various oils based on mineral oils or animal and vegetable oils and added with various organic additives or inorganic substances. (oil stain). Therefore, in the surface treatment process of metal workpieces, the first important process to be implemented is the need for these oils (degreasing, degreasing), otherwise it is difficult to ensure the quality of the conversion film in the subsequent proces...

Problems solved by technology

Because phosphate will directly promote the proliferation of microorganisms in water, excessive consumption of oxygen in water, the discharge and accumulation of phosphate will pollute the water quality of rivers, lakes and seas, affect the survival of aquatic organisms and animals, and destroy the ecological balance. Discharge of phosphorus waste is already limited by environmental regulations
