Embodiment 1

[0021] Example 1: 500g deionized water, add 80g ethanol, add 3.5g BTSE while stirring, let it stand for 2 to 5 days, the solution is transparent and clear, then add 25gA-151, 15gr-UPS while stirring, after the solution is transparent and clear, use 4g of acetic acid was used to adjust the pH, and then 1.5g of propylated zirconia was added to replenish the water to 1000g.

[0022] First, the cold-rolled steel is washed with degreasing water. The degreasing solution is best to use a formula that does not contain phosphorus to achieve phosphating-free production in the entire production line. After degreasing and washing, it can directly enter the aforementioned silanization treatment agent for treatment. A layer of coating can be obtained on the surface of the metal substrate, and then it can be washed or not washed to the next process-drying according to the process requirements, and powder spraying and other processes can be carried out after drying.

Embodiment 2

[0023] Example 2: 500g deionized water, add 100g ethanol, add 6g BTSE while stirring, let it stand for 2-5 days, the solution is transparent and clear, then add 20gA-151, 30gr-UPS while stirring, after the solution is transparent and clear, use 10g Acetic acid was used to adjust the pH, and then 1g of propylated zirconia and 3g of titanium isopropoxide were added to make up water to 1000g.

[0024]First, the aluminum alloy is degreased and washed with water. It is best to use a phosphorus-free formula for the degreasing solution to achieve non-phosphating production in the entire production line. After degreasing and washing, it can be directly treated in the aforementioned silanization treatment agent. The treatment time is 100 seconds. A layer of coating can be obtained on the surface of the substrate, and then it can be washed or not washed according to the process requirements to the next process-drying, and powder spraying and other processes can be carried out after dryin...

Abstract

The invention relates to a metal surface silanization treatment agent and a metal surface silanization treatment method using the same, and in particular relates to a non-phosphorus metal surface treatment method which replaces or partially replaces the traditional zinc phosphorization and iron phosphorization process. The metal surface silanization treatment agent comprises organosilane, organic acid, alcohol, a promoter and deionized water; and the mixed silanol solution can generate a surface protective film on a metal matrix. The surface silanization treatment agent has the advantages of no need of heating, no phosphorus and sediments and heavy metals, less energy consumption and simple management method, and the treatment agent can provide excellent adhesive force for combination between metal substrates and polyester, epoxy, acrylic and other types of coatings. The metal surface silanization treatment agent is particularly applicable to non-phosphorus environmentally-friendly conversion coating treatment on surfaces of cold rolled steel, zinc, iron, aluminum and aluminum alloys.

Description

technical field [0001] The invention relates to a silanization treatment agent on the metal surface and a process method for the silanization treatment on the metal surface. Background technique [0002] Since the British Charles Ross obtained the patent of phosphating treatment process in 1869, after more than a century of development, phosphating treatment has been widely used in pre-painting treatment, lubrication, anti-rust 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. 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 lub...
