Embodiment 1

[0018] A kind of antibacterial and anticorrosion metal surface treatment agent, it is made up of the raw material of following weight part:

[0019] Hydrolyzed polymaleic anhydride 0.6, triglyceride 0.04, polyvinyl alcohol 10-15, sericin 6, boric acid 0.07, yttrium nitrate hexahydrate 0.05, silane coupling agent KH-550 0.4, water 200, calcium ascorbate 0.2, coconut oil Acid diethanolamide 1, pyrithione zinc 0.2, Cathone 0.3, simethicone 0.08.

[0020] A kind of preparation method of antibacterial anticorrosion metal surface treatment agent, it is characterized in that comprising the following steps:

[0021] (1) Take sericin, add 40% 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 pyrithione zinc and Cathone, stir evenly, add triglyceride, heat to 50°C, add 50% of the remaining water weight, keep warm and stir for 20 minutes to obtain t...

Abstract

The invention discloses an antibacterial anticorrosive metal surface treatment agent which is composed of the following raw materials, by weight, 0.4-0.6 part of hydrolytic polymaleic anhydride, 0.02-0.04 part of triglyceride, 10-15 parts of polyvinyl alcohol, 4-6 parts of sericin, 0.07-0.1 part of boric acid, 0.05-0.1 part of yttrium nitrate hexahydrate, 0.4-1 part of a silane coupling agent KH-550, 160-200 parts of water, 0.1-0.2 part of calcium ascorbate, 1-2 parts of coco fatty acid diethanolamide, 0.2-1 part of zinc pyrithione, 0.1-0.3 part of Casson and 0.08-0.1 part of dimethicone. According to the invention, water-soluble polymer polyvinyl alcohol and sericin are mixed, and then silanization treatment is carried out. After hydrolysis of silane, an adsorption type film can be formed on metal surface so as to isolate water molecules and oxygen molecules in the environment, thus having a protective effect. Through boric acid modification, tensile strength and heat stability of blend films can be enhanced.

Description

technical field [0001] The invention mainly relates to the field of metal surface treatment agents, in particular to an antibacterial and anticorrosion 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 anodic...
