Composite iron-titanium powder and its production process

Abstract

A composite ferro-titanium powder and its production are disclosed. The components consist of ST antirust powder 1-8 proportion, barium sulfate 1-8 proportion, iron oxide red 0.1-2.5 proportion, iron oxide yellow or sun proof yellow 0.1-2.5 proportion and accessories 0.1-0.5 proportion. The accessories are selected from one kind or above of silicane coupling agent, titanic butyrin, titanic carbethoxy and aluminate ester. The process is carried out by adding ST anti-rust powder and barium sulfate into high-speed mixer, adding into iron oxide red, iron oxide yellow or sun proof yellow successively, adding into accessories into high-speed mixer, low-speed agitating for 3-10 mins and high-speed agitating for 10-20 mins. It costs low and has better stability, deposit and rust resistances.

Description

technical field [0001] The invention relates to an antirust pigment, in particular to a novel antirust pigment-composite iron-titanium powder for various oily and water-based paints and its production process. Background technique [0002] Hongdan antirust paint has excellent antirust performance, has a history of nearly a hundred years of use, and has a huge amount of use. However, in the past two years, the amount of red lead antirust paint has been decreasing year by year, and the development trend is to gradually reduce and prohibit its use. Dan antirust paint still accounts for a large proportion of 10%, and it also has a certain market share abroad. Although other antirust pigments are less toxic than red lead or even non-toxic, their antirust performance is far lower than that of red lead, and some antirust pigments are expensive, which limits the field of use. [0003] Anti-rust paint is the primer for anti-corrosion treatment of traditional steel structures, and t...

AI Technical Summary

Problems solved by technology

But its production cost is high, and there is no fundamental breakthrough in technology

The development of non-toxic anti-rust pigments in my country is also facing similar problems. Although non-toxic anti-rust pigments have also appeared, they are more expensive and cannot fundamentally solve the increase in protection expenses after the ban on the use of red lead anti-rust paint , or the trend that the protection cost does not increase but the anti-rust performance declines
