Problems solved by technology

[0004] At present, although the traditional phosphate conversion and chromate passivation surface treatment technologies can achieve good results, the waste liquid discharged during the treatment process contains heavy metal ions such as zinc, manganese, nickel, chromium, and carcinogenic substances such as sub-environmental protection and fluorine-free. Substances that pollute the environment are very serious, and the metal surface silanization treatment technology is considered to be expected to replace phosphate conversion treatment and chromate passivation treatment because it does not involve substances that are harmful to the environment, the production process has low energy consumption, and the technology has a wide range of applications. It is the latest development direction of metal surface protection alone

Abstract

The invention discloses a polyaniline sol metal surface treatment agent. The polyaniline sol metal surface treatment agent is composed of, by weight, 1-2 parts of seignette salt, 110-120 parts of polyaniline sol, 1-2 parts of polydimethylsiloxane, 0.7-1 part of silane coupling agent kh550, 2-4 parts of sodium fluorosilicate, 3-5 parts of triethyl phosphate, 0.1-0.2 part of 2-mercaptobenzimidazoleand 0.5-1 part of nickel aminosulfonate. The added sol can effectively improve the adhesive force intensity of a coated film with metal, and therefore the metal protectiveness is improved.

Description

technical field [0001] The invention belongs to the field of surface treatment agents, in particular to a polyaniline sol 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 dissolution of the metal or promo...
