Abstract

The invention discloses a treatment process of a rust-proof bolt. The treatment process of the rust-proof bolt comprises the following steps of S1, surface cleaning; S2, surface passivation; S3, smearing of a rust-proof solution; S4, drying, wherein the rust-proof solution comprises, by weight, 20-25 parts of trisodium phosphate, 2-5 parts of sodium silicate, 3-5 parts of urotropin, 3-5 parts of 2-mercapto benzimidazole, and 80-90 parts of water. The treatment process of the rust-proof bolt has the following advantages that trisodium phosphate can form a phosphating film on the surface of thebolt, and sodium silicate can form an oxidation film on the surface of the bolt, so that an anti-oxidation function and a rust-proof function are achieved, and the rust-proof cycle is long. Urotropincan improve the corrosion resistance of the bolt and has a complexing function to improve the adhesive force of the oxidation film and the phosphating film on the surface of the bolt. 2-mercapto benzimidazole has a good anti-oxidation effect, can improve the anti-oxidation and rust-proof effects of the bolt and improve the storage performance of the rust-proof solution, and has good corrosion inhibition.

Description

technical field

[0001] The invention relates to the technical field of bolt treatment technology, more specifically, it relates to a treatment technology of antirust bolts. Background technique

[0002] After the bolts are produced in the workshop, they are usually treated with anti-rust oil to ensure that they will not rust during storage.

[0003] The Chinese patent with the notification number CN103421393B discloses a steel antirust solution, which is composed of the following components according to the weight ratio: 4 parts of diethylene glycol dibutyl ether, 12 parts of isopropyl myristate, calcium palmitate 7 parts, 5 parts of triethanolamine oleate, 6-8 parts of zinc naphthenate, 58-63 parts of rubber oil.

[0004] As long as the components of this anti-rust liquid are oils and esters, they are more likely to deteriorate, resulting in a shorter anti-rust cycle, which needs to be improved. Contents of the invention

[0005] In view of the deficiencies in the prior...
