Embodiment 1

[0018] In the present invention, each raw material component of the multifunctional brushing agent and its content are 560g / L of phosphoric acid, 20g / L of citric acid, 15g / L of surface activity, and 405g / L of water. The preparation method of the multifunctional brushing agent is: first weigh Quantitative water, then add phosphoric acid, citric acid, and surfactant and stir at 40°C for 30 minutes until a uniform solution is formed, stop stirring, and cool out of the pot.

Embodiment 2

[0020] In the present invention, each raw material component of the multifunctional brushing agent and its content are 360g / L of phosphoric acid, 30g / L of citric acid, 10g / L of surface activity, and 600g / L of water. The preparation method of the multifunctional brushing agent is: first weigh Quantitative water, then add phosphoric acid, citric acid, and surfactant and stir at 45°C for 45 minutes until a uniform solution is formed, stop stirring, and cool out of the pot.

Embodiment 3

[0022] In the present invention, each raw material component of the multifunctional brushing agent and its content are 560g / L of phosphoric acid, 15g / L of citric acid, 20g / L of surface activity, and 250g / L of water. The preparation method of the multifunctional brushing agent is: first weigh Quantitative water, then add phosphoric acid, citric acid, and surfactant and stir at 60°C for 60 minutes until a uniform solution is formed, stop stirring, and cool out of the pot.

Abstract

The invention discloses a multifunctional brush coating agent which is prepared from 360-700g / L of phosphoric acid, 10-30g / L of citric acid, 10-20g / L of surfactant and 250-600g / L of water. Heating isneeded, preparation is carried out at the constant temperature, one product has three functions of oil removal, dust removal and rust prevention, operation is easy, and only wiping is needed.

Description

【Technical field】 [0001] The invention relates to the field of chemical industry, in particular to a multifunctional brushing agent and a preparation method thereof. 【Background technique】 [0002] At present, many steel parts such as cold-rolled plates and steel pipes are prone to rust after being placed for a period of time. The general rust removal methods are divided into two types, one is pickling and the other is mechanical rust removal. Both of these two types of equipment require a large investment in equipment, and if the surface after pickling is not treated with antirust, it will accelerate the corrosion of the workpiece. And mechanical derusting will bring unnecessary stress. The three-in-one product of oil removal, rust removal and anti-rust developed by our company only needs to be wiped gently on the rusted place several times, and the scale will disappear, thus returning to the original color of the metal substrate, and after treatment High-quality workpiec...
