Problems solved by technology

Most of the anti-rust agents currently used are made of nitrite, which will cause personal injury when used. The anti-rust period is generally only about 10 days, and it is not resistant to salt spray corrosion, which is far from meeting the needs of parts storage. and also itches the need for long-distance transport

Abstract

The invention provides an emulsified-type metal antirust agent. The emulsified-type metal antirust agent comprises, by weight, 1-5 parts of monobasic acid, 4-10 parts of dibasic acid, 2-6 parts of tribasic acid, 4-10 parts of monoethanolamine, 2-6 parts of diethanol amine, 40-50 parts of triethanolamine, 10-20 parts of polyacrylate, 20-30 parts of butyl acrylate, 10-20 parts of tricresyl phosphate, 30-50 parts of olefin succinic acid, 20-30 parts of dodecyl phenyl succinic acid, 30-40 parts of Octadecylamine N-oleoyl Sarcosinate and 600-700 parts of water. The emulsified-type metal antirust agent is resistant to salt mist, long in rust-proof life and good in rust-proof effect. The rust-proof life can reach 1-4 months. Moreover, the source of the raw materials is wide, production cost can be effectively reduced, and the emulsified-type metal antirust agent is particularly suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of antirust agents, in particular to emulsified metal antirust agents Background technique [0002] In the metal processing and machinery manufacturing industries, the processed metal parts need to be rust-proof, and the surface of the metal parts needs to be coated with anti-rust agent, otherwise they will be rusted soon and cannot be used, especially in ocean transportation. Parts are more likely to rust due to erosion by seawater salt spray. Most of the anti-rust agents currently used are made of nitrite, which will cause personal injury when used. The anti-rust period is generally only about 10 days, and it is not resistant to salt spray corrosion, which is far from meeting the needs of parts storage. And also itches the need for long-distance transport. Contents of the invention [0003] The purpose of the present invention is to disclose an emulsified metal antirust agent to solve one or more of th...
