Embodiment Construction

[0016] The following is an embodiment of the invention:

[0017] The present invention comprises 15 parts of sodium benzoate, 15 parts of urotropine, 55 parts of ethanol, 2 parts of β-naphthol, 8 parts of potassium ferrocyanide, 10 parts of sodium nitrite, Freon-11 and Freon-12, It is characterized in that: sodium benzoate, urotropine, β-naphthol, potassium ferrocyanide, sodium nitrite are added to ethanol, combined and stirred evenly, and the filtrate and filter residue are further filled into the tank quantitatively, and installed The valve and tank are further filled with freon-11 and freon-12 to combine to obtain the propellant, and the ratio of the filtrate to freon-11 and freon-12 is 1:2:2.

[0018] The proportions of the above weight ratios, especially the proportions of the filtrate to Freon-11 and Freon-12, can also be appropriately replaced with different proportions, and the effect after the replacement remains unchanged.

[0019] The propellant is automaticall...

Abstract

The invention, which belongs to the field of chemical antirusting technology, relates to a metal antirusting spray agent for packaging paper, which is sprayed on the surfaces of metal materials and metal product-packaging paper to prevent rusting. The metal antirusting spray agent consists of 15 parts of sodium benzoate, 15 parts of urotropin, 55 parts of ethanol, 2 parts of Beta-naphthol, 8 parts of potassium ferrocyanide, 10 parts of sodium nitrite, freon-11 and freon-12. The metal antirusting spray agent is characterized in that: the sodium benzoate, the urotropin, the Beta-naphthol, the potassium ferrocyanide and the sodium nitrite are added into the ethanol and uniformly stirred, liquid and residue are then filtered, the filtrate is further quantitatively filled into a tank, a valve is mounted, the freon-11 and the freon-12 are further filled into the tank, so that the spray agent is obtained, and the proportion of the filtrate, the freon-11 and the freon-12 by part is 1:2:2. When in use, the metal antirusting spray agent is forcibly shaken to become uniform, the valve is pressed, so that the metal antirusting spray agent is sprayed on a piece of packaging paper or a packaging carton, the content of the metal antirusting spray agent on the paper is 6g/m2 to 8g/m2, a piece of antirusting paper is obtained after a few minutes, and thereby various packaging can be done.

Description

technical field [0001] The invention belongs to the technical field of antirust in chemical industry, and relates to a metal antirust spray agent for wrapping paper, which is used for antirust spraying on the surface of the wrapping paper of metal materials and metal products. Background technique [0002] Metal is the most important structural material in the modern machinery industry, national defense industry and other departments. It is easily corroded by the chemical and electrochemical effects of the external environment. It is usually packaged with paper products, or paper products are used for packaging. To seal metal and its products. However, due to the insufficient sealing degree of the packaging during use, the existence of atmospheric corrosion is easy to corrode and rust, and the loss caused is about 100%. Corrosion and rusting of the metal requires time spent on rust removal or even damage. To protect the metal from rust, the main measures currently taken are...
