Abstract

The invention discloses a modified nanoscale titanium dioxide-containing metal rust prevention wax and a preparation method thereof. The modified nanoscale titanium dioxide-containing metal rust prevention wax comprises raw materials in parts by weight: 70-80 of PE (polyethylene) wax, 30-40 of styrene, 1-2 of dicyclopentadienyl iron, 4-5 of film-forming resin, 1-2 of modified diatomaceous earth, 10-15 of dibutyl phthalate, 0.9-1.1 of fatty alcohol polyoxyethylene ether sulfate, 2-3 of dibutyltin dilaurate, 2-4 of tribasic lead sulphate, 3-5 of N-phenyl-2-naphthylamine, 1-3 of dodecencylsuccinic acid, 5-7 of modified nanoscale titanium dioxide, 1-3 of Tween 80, and 0.8-1.2 of catechol. The rust prevention wax not only has good rust prevention property and is convenient to use, but also adds the modified nanoscale titanium dioxide into raw materials; and compared with the similar products, the rust prevention wax has better temperature resistance performance and better surface flatness, as well as good flowability, salt fog resistance, and heat and humidity resistance.

Description

technical field [0001] The invention relates to a metal antirust wax containing modified nano-level titanium dioxide and a preparation method thereof, belonging to the technical field of metal antirust. Background technique [0002] Under natural storage conditions, iron and steel metals are prone to corrosion due to environmental and other factors, thereby reducing or losing their use value, resulting in safety accidents and economic losses. The amount of direct economic loss caused by metal corrosion in our country is huge every year. [0003] Metal corrosion is mainly divided into chemical corrosion and electrochemical corrosion in terms of mechanism. There are many reasons for corrosion, such as mechanical damage, surface defects, internal defects, environmental factors, etc. Common corrosion factors include contact with air, surface pollution, and electrochemical corrosion. and surface scratches. Contents of the invention [0004] The purpose of the present inve...
