Embodiment 3
[0024] The weight ratio of each raw material is: 20 parts of sodium benzoate, 10 parts of sodium nitrite, 8 parts of polymer compound synergistic active agent, 6 parts of ethylenediaminetetraacetic acid, 5 parts of sodium tripolyphosphate, dipotassium benzene 5 parts, 8 parts of polyethylene glycol, 6 parts of urea, 5 parts of glycerin and 70 parts of water.
[0025] Compound method of the present invention carries out according to the following steps:
[0026] (1) Preparation of raw material aqueous solution: Weigh sodium phenylpotassium, sodium nitrite, ethylenediamine tetraacetic acid, sodium tripolyphosphate, polyethylene glycol and urea respectively according to the stated ratio, and put each raw material in an acid-resistant container Add water and heat to dissolve, and stir evenly. The amount of water added is based on the fact that all raw materials are dissolved into a solution state to make semi-finished aqueous solution raw materials respectively. The temperature co...

Abstract
The invention relates to a metal surface rust protection solution which is prepared by following raw materials of sodium benzoate, sodium nitrite, a high polymer composite enhanced active agent, ethylenediamine tetraacetic acid, sodium tripolyphosphate, dipotassium benzene, polyethylene glycol, urea, glycerol and water. By using the rust protection solution, erosion resistance of a metal surface can be improved, a moist insulation property and an air insulation property of a protective layer are improved, and therefore the metal surface is enabled to have a reliable and longstanding rust protection effect. In addition, the rust protection solution has a function of providing excellent rust protection for metal materials and metal products, is reusable, without liquid waste discharging, without acid mist which can cause pollution to the environment, safe and reliable, and easy to operate, can not burn the skin in use, and causes no stimulation and no harm to human bodies.
Description
technical field [0001] The invention belongs to the technical field of metal surface treatment, and relates to an antirust liquid for performing anticorrosion pretreatment on the surface of metal materials and metal products. Background technique [0002] Metal corrosion protection has always been a very important research and development in the world. According to statistics, the weight of steel produced every year in the world and the metal products that cannot be used due to corrosion is about one-third of the annual output of metal. And the corrosion of metal products directly affects its use value or even scrapping. Especially metal materials are rusted due to air pollution and corrosion when they are stored in steel factories, machinery processing plants, and building materials markets. The loss of steel products all over the world due to corrosion is huge. In the existing technology, the traditional methods for removing the rust layer on the surface of metal materia...
