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 treated in an environmentally friendly way; in addition, most of the phosphating treatment needs to be carried out under heating conditions, which consumes a lot of energy, the process is complicated, and the operation is inconvenient
Silane surface treatment technology has appeared, but the film formation of silane surface treatment agent on the metal surface is unstable, the anti-corrosion performance is unstable, and the effect is not good

Embodiment Construction

[0018] A silanization protective treatment agent for the surface of anti-corrosion galvanized steel sheet, which is made of the following components, and the weight (g) of each raw material component in each 500g mixed solution is:

[0019] Ammonium carbonate 1, hexamethylenetetramine 2, zirconium fluoride 1, rosin 5, trihydroxyethyl isocyanurate 1, maleic anhydride 9, diethylene glycol butyl ether 6, isopropanol 8 , Urea 2, benzoic acid 6, N-2-(aminoethyl)-3-aminopropyltrimethoxysilane 20, the balance is deionized water.

[0020] The preparation method of the metal surface silanization protection treatment agent includes the following steps:

[0021] (1) Heat and melt the rosin to 110-115°C, add diethylene glycol butyl ether and N-2-(aminoethyl)-3-aminopropyltrimethoxysilane, stir and react for 35-50 minutes;

[0022] (2) The temperature is raised to 145-160°C, trihydroxyethyl isocyanurate and maleic anhydride are added, and the reaction is stirred for 40-50 minutes;

[0023] (3) Cont...

Abstract

The invention discloses a surface silanization protection treatment agent for corrosion-resistant galvanized steel plates. The surface silanization protection treatment agent is prepared from the following ingredients by weight (gram) in every 500g of mixture liquid: 1-2g of ammonium carbonate, 2-3g of hexamethylene tetramine, 1-2g of zirconium fluoride, 3-5g of rosin, 1-2g of trihydroxyethyl isocyanurate, 6-9g of maleic anhydride, 4-6g of diethylene glycol butyl ether, 5-8g of isopropanol, 1-2g of urea, 4-6g of benzoic acid, 15-20g of N-2-(aminoethyl)-3-aminopropyl trimethoxysilane and the balance of deionized water. According to the surface silanization protection treatment agent, rosin serving as a reaction raw material and is polymerized with raw materials, such as maleic anhydride and silane, and then, a strong protecting film 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 a metal surface and a process for using the silanization treatment agent on the metal surface. Background technique [0002] Phosphating treatment has been widely used in metal coating pretreatment, lubrication, rust prevention and other industries. Especially in the coating pretreatment industry, phosphating treatment is one of the most commonly used pretreatment methods. Phosphating treatment is a process in which a metal is reacted in an acidic phosphate solution to form a phosphate protective film on its surface. 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,...
