Embodiment 1

[0024] Preparation of degreasing agent: Add 500g of water to a 1000ml beaker, add 50g of fluorocarbon surfactant 3-trimeric epoxyhexafluoropropane amidopropyl (2-sulfurous acid) ethyl dimethyl ammonium, and stir for 10 minutes at room temperature Then add synthetic penetrant A50g, stir at normal temperature for 10 minutes; then add cationic surfactant fluorocarbon-hydrocarbon flexible bridge mixed chain diquaternary ammonium 200g, stir for 10 minutes; add anhydrous sodium silicate 100g, stir for 10 minutes Add 100 g of sodium metasilicate pentahydrate and stir for 60 minutes to obtain the degreasing agent.

[0025] The method of use is: the general tank dosage is 3-5%, that is, 30-50 kg of degreasing agent can be prepared in one ton of clean water; the daily addition amount depends on the specific condition and quantity of the workpiece.

Embodiment 2

[0027] Preparation of degreasing agent: Add 1000g of water to a 2000ml beaker, add 100g of fluorocarbon surfactant 3-tripolyepoxyhexafluoropropane amidopropyl (2-sulfurous acid) ethyldimethylammonium, and stir at room temperature for 20 minutes Then add synthetic penetrant A100g, stir at normal temperature for 20 minutes; then add 400g of cationic surfactant fluorocarbon-hydrocarbon flexible bridge mixed chain diquaternary ammonium, stir for 20 minutes; add anhydrous sodium silicate 200g, stir for 20 minutes Add 200 g of sodium metasilicate pentahydrate and stir for 100 minutes to obtain the degreasing agent.

[0028] The method of use is: the general tank dosage is 3-5%, that is, 30-50 kg of degreasing agent can be prepared in one ton of clean water; the daily addition amount depends on the specific condition and quantity of the workpiece.

Abstract

The invention relates to a normal-temperature phosphorus-free degreasing agent.A preparation method of the normal-temperature phosphorus-free degreasing agent includes: adding 500g of water into a 1000ml beaker, then adding 50g of fluorocarbon surfactant, and stirring under normal temperature for 10-20 minutes; adding 50g of synthesized penetrating agent A, and stirring under normal temperature for 10-20 minutes; adding 200g of cation surfactant, and stirring for 10-20 minutes; adding 100g of anhydrous sodium silicate, and stirring for 10-20 minutes; adding 100g of sodium metasilicate pentahydrate, and stirring for 60-120 minutes to obtain the degreasing agent.The degreasing agent is free of phosphorus, capable of being used under normal temperature, efficient and environmentally friendly and only needs 5-10 minutes to completely remove the greasy dirt on the surface of a workpiece soaked in the degreasing agent.

Description

technical field [0001] The invention relates to the field of oil stain treatment, in particular to a normal-temperature phosphorus-free degreasing agent for treating heavy oil and heavy stains on workpieces. Background technique [0002] Generally, degreasing agents contain a large amount of phosphorus, and the temperature used is generally between 45-65°C. At room temperature, these degreasing agents have extremely poor ability to remove oil stains. They need to soak the workpiece for more than 2-12 hours to barely remove oil stains. [0003] Publication No. CN104498971A discloses a normal temperature phosphorus-free degreasing agent for quickly removing putty on the surface of metal workpieces. The degreasing agent is composed of sodium hydroxide, sodium metasilicate, sorbitol, polyvinylpyrrolidone, hydroxyethylcellulose, di Sodium octyl sulfonate, triethanolamine and appropriate amount of water in the system. It has the characteristics of normal temperature, no phosphoru...
