Embodiment Construction
[0019] The present invention will be described in detail below, but it should be noted that the implementation of the present invention is not limited to the following embodiments.
[0020] A water-based antirust agent for hot-rolled and cold-rolled steel plates, said antirust agent is made of the following raw materials in parts by mass: 2-methyl-5-mercapto-1,3,4-thiadiazole 8 -18 parts, 5-10 parts of sebacic acid, 8-10 parts of triethanolamine, 3-6 parts of polyol, 4-8 parts of phosphate, and the balance is deionized water.
[0021] Described polyhydric alcohol is polyethylene glycol or glycerol.
[0022] Described phosphate is potassium phosphate or sodium phosphate.
[0023] A preparation method of hot-rolled and cold-rolled steel plate water-based antirust agent, comprises the following steps:
[0024] 1) weighing the raw materials according to the above-mentioned parts by mass for subsequent use;
[0025] 2) Add 2-methyl-5-mercapto-1,3,4-thiadiazole into the reaction ...

The invention provides a water-based rust inhibitor for hot-rolled and cold-rolled steel plates. The rust inhibitor is prepared from, by mass, 8-18 parts of 2-methyl-5-mercapto-1,3,4-thiadiazole, 5-10parts of sebacic acid, 8-10 parts of triethanolamine, 3-6 parts of polyol, 4-8 parts of phosphate salt, and the balance of deionized water. The rust inhibitor generates a high-strength uniform and complete protection film on a steel plate, and exists as an independent phase to completely isolate metal and a solution and reduce the metal dissolving rate in order to protect a metal material. The rust inhibitor has the advantages of good antirust effect, compounded production technology, normal temperature use, energy saving and environmental protection, solving of an existing technological problem that a lot of rusts appearing in the storage process of the hot-rolled steel plates in a process room affect the phosphating and coating quality of car plate products, good antirust effect, long period, and cooperative use with antirust oil. The rust inhibitor uses the thiadiazole as a rust inhibitor monomer to substitute a traditional nitrate salt, so the rust inhibitor is safe, is friendly to the environment, and reduces the cost.
Description
technical field [0001] The invention relates to the field of water-based metal antirust agents, in particular to a water-based antirust agent for hot-rolled and cold-rolled steel plates and a preparation method thereof. Background technique [0002] Under certain conditions in the atmosphere, metals will react chemically or electrochemically with oxygen, water and other substances to cause corrosion. Among them, cold and hot rolled steel sheets are widely used in many automobile manufacturers due to their good coating performance and excellent stamping performance. The surface corrosion of hot and cold-rolled steel sheets is a product quality issue that steel companies are most concerned about. Steel corrosion will seriously affect the phosphating and coating treatments of automotive sheets. Therefore, there is an urgent need to develop a water-based rust inhibitor that is highly efficient, environmentally friendly and suitable for steel surface corrosion. At present, anti...
