Example Embodiment

[0017] Example 1:

[0018] An environmentally friendly non-toxic metal surface treatment agent, which is composed of the following parts by weight of raw materials:

[0019] Alkenyl succinate 4, tetramethylglutaric acid 0.2, α-alkenyl sodium sulfonate 0.8, sodium polycarboxylate 2, N,N-diethylaniline 0.6, tetraethylammonium tetrafluoroborate 0.3, Sodium diacetate 0.2, sodium pyrrolidone hydroxy acid 0.7, diethanolamine 3, triethanolamine borate 4, yttrium nitrate hexahydrate 0.05, silane coupling agent KH-550 0.4, water 200.

[0020] An environment-friendly and non-toxic metal surface treatment agent preparation method includes the following steps:

[0021] (1) Take sericin, add 60% of the above water weight, stir evenly, add silane coupling agent KH-550, yttrium nitrate hexahydrate, stir and disperse at 1000 rpm for 20 minutes to obtain silane liquid;

[0022] (2) Mix sodium diacetate and sodium pyrrolidone hydroxy acid, add 70% of the remaining water weight, and stir evenly to obtain...

Abstract

The invention discloses an environment-friendly non-toxic metal surface treatment agent which is prepared from the following raw materials in parts by weight: 4-6 parts of alkenyl succinate, 0.1-0.2 part of tetramethyl glutaric acid, 0.8-2 parts of alpha-olefin sulfonate, 1-2 parts of sodium polycarboxylic acid, 0.6-1 part of N,N-diethylaniline, 0.2-0.3 part of tetraethylammonium tetrafluoroborate, 0.1-0.2 part of sodium diacetate, 0.7-1 part of pyrrolidone hydroxy acid sodium, 2-3 parts of diethanol amine, 4-5 parts of triethanolamine borate, 0.05-0.1 part of yttrium nitrate hexahydrate, 0.4-1 part of a silane coupling agent KH-550 and 150-200 parts of water. The metal surface treatment agent has the advantages of being non-toxic and pollution-free, good in environment-friendly property, good in anticorrosive and antibacterial properties, good in storage stability and long in service life.

Description

technical field [0001] The invention mainly relates to the field of metal surface treatment agents, in particular to an environment-friendly and non-toxic metal surface treatment agent. Background technique [0002] Metal surface treatment agent refers to the general term for various chemical agents for metal surface treatment. Metal surface treatment includes degreasing, rust removal, phosphating, antirust and other substrate pretreatments, which are prepared for metal coating technology and metal protection technology. The quality of substrate pretreatment has a great influence on subsequent coating preparation and metal use. The water-soluble rust inhibitor can be dissolved in water to form an aqueous solution, and the metal can prevent corrosion and rust after being treated with this aqueous solution. Their antirust effect can be divided into three categories. [0003] ①The metal and the antirust agent form an insoluble and dense oxide film, thus preventing the ano...
