Problems solved by technology

The phosphating treatment process uses phosphoric acid, zinc, manganese, and nickel as the main raw materials, causing serious environmental pollution such as heavy metals, phosphorus, and nitrite, and will more or less produce sediment and harmful gases during the treatment process, which affects production. If it is carried out normally, the discharged wastewater COD and heavy metals will endanger the environment if it is not treate

Embodiment Construction

[0018] A stainless steel plate surface silanization protective treatment agent is made of the following components, and the weight (grams) of each raw material component in every 500 grams of mixed solution is:

[0019] Succinic acid 3, ammonium molybdate 2, gelatin 8, lanthanum nitrate 3, rosin 5, trishydroxyethyl isocyanurate 2, maleic anhydride 12, diethylene glycol butyl ether 6, propylene glycol 8, acetic acid 3. Urea 1, aminopropyltriethoxysilane 12, and the balance is deionized water.

[0020] The preparation method comprises the following steps:

[0021] (1) Heat and melt the rosin to 110-115°C, add diethylene glycol butyl ether and aminopropyl triethoxysilane, and stir for 35-50 minutes;

[0022] (2) Heat up to 145-160°C, add trihydroxyethylisocyanurate, maleic anhydride, acetic acid, and stir for 40-50 minutes;

[0023] (3) Continue to heat up to 190-205°C, add ammonium molybdate, gelatin, and urea, and stir for 40-50 minutes;

[0024] (4) Cool down to 80-90°C, ad...

Abstract

The invention discloses a surface silanization protection treatment agent for stainless steel plates. The surface silanization protection treatment agent is prepared from the following ingredients in weight (gram) in every 500g of mixture liquid: 2-3g of butane diacid, 1-2g of ammonium molybdate, 5-8g of gelatin, 2-3g of lanthanum nitrate, 3-5g of rosin, 1-2g of trihydroxyethyl isocyanurate, 10-12g of maleic anhydride, 4-6g of diethylene glycol butyl ether, 5-8g of propylene glycol, 2-3g of acetic acid, 1-2g of urea, 10-12g of aminopropyl triethoxysilane and the balance of deionized water. According to the surface silanization protection treatment agent, rosin serving as a reaction raw material is polymerized with raw materials, such as maleic anhydride and silane, and then, strong protecting films can be formed on the surface of metal; and the corrosion resistance of metallic matrixes is enhanced.

Description

technical field [0001] The invention relates to a silanization treatment agent on the metal surface and a process for silanization treatment on the metal surface. Background technique [0002] Phosphating treatment has been widely used in metal coating pretreatment, lubrication, antirust and other industries. Especially in the coating pretreatment industry, phosphating treatment is one of the most commonly used pretreatment methods. Phosphating treatment is the process of forming a phosphate protective film on the surface of a metal after reacting in an acidic phosphate solution. Phosphate 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. The phosphating treatment process uses phosphoric acid, zinc, manganese, and nickel as the main raw materials, causing serious environmental pollution such as heavy metals, phosphorus, and nitrite,...
