Composite iron-titanium powder and its production process

Abstract

The invention relates to an antirust pigment and its production process. The antirust pigment consist of ST antirust powder with grain size 400-600 meshes 1-8 proportion, barium sulfate with grain size 400-600 meshes 1-8 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 production process is as follows: adding the ST antirust powder and the barium sulfate into high-speed mixer, simultaneously adding the prepared accessories into the high-speed mixer, starting the high-speed mixer, firstly low-speed agitating for 3-10 mins, then high-speed agitating for 10-20 mins. Compared with other antirust pigment, the antirust pigment of the invention has a better dispersibility, and partially replaces the antirust paint prepared by other antirust pigment, its main indexes such as stability, anti-deposition and antirust property etc. all approach or reach the performance requirement of the antirust paint prepared by the replaced pigment at these aspects, and its performance-price ratio is significantly high, the cost of per ton decreases 1000-2000 yuan.

Description

technical field [0001] The invention relates to an antirust pigment, in particular to a novel antirust pigment 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 the anti-rust pigments used to m...

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
