Abstract

The invention discloses a metal rust inhibitor containing peregal O. The metal rust inhibitor is prepared from the following raw materials in parts by weight: 2-5 parts of urea, 5-8 parts of liquefied paraffin, 3-5 parts of acetyl tri(2-ethylhexyl)ester citrate, 4-6 parts of acrylic acid, 0.2-0.3 part of zinc powder, 3-5 parts of epoxidized rice bran oil, 2-3 parts of dimethylbenzene, 3-5 parts of polyethylene wax, 0.2-0.3 part of potassium persulfate, 0.3-0.5 part of borax, 1-2 parts of zinc naphthenate, 0.5-0.9 part of 2-methylimidazole, 1.3-1.5 parts of benzotriazole, 0.5-1.5 parts of methenamine, 1.1-1.7 parts of 2-n-octyl-4-isothiazolinone, 1.2-1.9 parts of peregal O and 95-105 parts of water. The metal rust inhibitor has rust inhibiting time as long as 4-6 months, has better adaptability to copper and aluminium and can form films on the metal surfaces while carrying out slow release and rust inhibition, thus lengthening the rust inhibiting time.

Description

technical field [0001] The invention relates to the field of anti-rust agents, in particular to a metal anti-rust agent containing pepina O. Background technique [0002] Water-based anti-rust agent is a water-based anti-rust solution, which can effectively protect steel, iron and other materials from rusting. According to different anti-rust period requirements, if it is mixed with water in a certain ratio, the anti-rust period can reach several days to several months. If there are certain external packaging conditions, the anti-rust time can reach more than one year. Most of the existing antirust agents have poor antirust performance, and there is an urgent need for a metal antirust agent with good antirust performance. Contents of the invention [0003] The object of the present invention is to provide a metal antirust agent with good antirust performance. [0004] The above purpose is achieved through the following schemes: [0005] A metal antirust agent containing...
