Embodiment 1

[0023] Produce 1000kg vitrifying agent, its preparation method comprises the following steps:

[0024] Step 1: Provide the following raw materials: 26kg vinyl silane, 53kg citric acid, 65kg sodium nitrate, 9kg acetic acid, 6kg propyl zirconia and 841kg tap water; provide the following equipment: a clean reaction kettle and a liquid agitator;

[0025] Step 2: under normal temperature and pressure, add 841 kg of tap water into the reactor, and the liquid stirrer stirs slowly;

[0026] Step 3: The liquid agitator keeps stirring, and at the same time, slowly add 26kg of vinylsilane, 53kg of citric acid, 9kg of acetic acid, 65kg of sodium nitrate, and 6kg of propylated zirconium to the reactor;

[0027] Step 4: The stirrer is continuously stirred for 0.5-1.0 hours, and tap water is added to adjust the density to 1.01-1.06 g / ml to obtain the ceramic agent.

[0028] The method of using the ceramic agent is as follows: dilute the ceramic agent with tap water at a ratio of 1:50-1:25 b...

Embodiment 2

[0030] Every 1000Kg vitrifier is made of the following raw materials:

[0031] 1kg vinylsilane, 10kg citric acid, 30kg sodium nitrate, 1kg acetic acid, 5kg propylzirconia and 953kg tap water.

[0032] The preparation method and the method of use are the same as in Example 1.

[0033] Example 2

[0034] Every 1000Kg vitrifier is made of the following raw materials:

[0035] 50kg vinyl silane, 100kg citric acid, 100kg sodium nitrate, 40kg acetic acid, 50kg propyl zirconia and 760kg tap water.

[0036] The preparation method and the method of use are the same as in Example 1.

Abstract

The invention provides a vitrification agent and a preparation method and a using method thereof. The preparation method of the vitrification agent mainly comprises the following steps: under the condition of continuous stirring, adding low-molecular-weight water-soluble silane, citric acid, a complexing agent, sodium nitrate and zirconium propyl oxide in water of a reaction kettle; and finally, adding water to regulate density. The vitrification agent is prepared from the following raw materials according to the formula: the low-molecular-weight water-soluble silane, the citric acid, the zirconium propyl oxide, the complexing agent, the sodium nitrate and the water. The using method of the vitrification agent comprises the step of only needing to dilute the vitrification agent with water.By the vitrification agent and the preparation method and the using method thereof, the technical problems of environmental pollution, complicated process, high energy consumption and high cost in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a ceramic agent and its preparation method and use method. Background technique [0002] Phosphating treatment is one of the most commonly used pretreatment methods in the coating pretreatment industry. Because the phosphating film formed by phosphating treatment is firmly combined with the substrate, has a microporous structure, and has good adsorption performance, it can greatly improve the coating quality. In addition, phosphating film also has good lubricity, insulation and corrosion resistance, so it is widely used in the manufacturing fields of automobiles, machinery manufacturing, aerospace and household appliances. Phosphating treatment has many advantages, but there are also many disadvantages that cannot be overcome by itself: the phosphating treatment process uses phosphoric acid, zinc, manganese, and nickel as the main raw materials, causing environme...
