Abstract
The invention relates to a preparation method of rust converting antirust powder for promoting dispersion of organic pigments in waterborne coatings, which adopts phosphorus concentrate powder rich in calcium fluorophosphate as a carrier, adopts B216 thixotropic agent as a modifier, and prepares the rust converting antirust powder by adding a rust converting agent D117, nanometer silica, and nanometer titanium dioxide and modifying calcium fluorophosphate powder through a certain modification process. The rust converting antirust powder has the advantages that the powder enables uniform dispersion of organic pigments in waterborne coatings without flooding phenomenon, both has rust converting antirust effect, and is applicable to oily and waterborne antirust paint.
Description
Technical field
The present invention relates to a kind of rust-inhibiting paint technical field, specifically a kind of with colored and have band rust antirust function, be not only applicable to oiliness (paint) but also be applicable to the antirusting powder of water-based (paint).
Background technology
As everyone knows, many pigment dyestuffs are directly used in aqueous industrial protective system, all exist dispersed bad problem, and this is because when producing in coating, these organism and water are incompatible.As when producing " the unleaded red lead paint of water-based ", just there is such problem in use red and the forever solid orange pigment dyestuff that waits.Rust-stabilising pigment composite iron-titanium powder mainly contains antirust function, but can not promote the dispersion of pigment dyestuff in water-based anticorrosive paint.Therefore, for a long time, composite iron-titanium powder just can only be used for solvent-thinned paint and can not be used for water-miscible paint and also do not have " band rust is antirust " this technology kind.
Summary of the invention
The object of the invention is to develop one and can promote pigment dyestuff to be well-dispersed in water-based system coating, there is again band rust antirust function, and can be applicable to the antirusting powder in oiliness, aqueous antirust paint.
A kind of preparation method who promotes pigment dyestuff to be scattered in the band rust antirusting powder in water-borne coatings of the present invention realizes by following scheme:
Take the natural phosphorus fine ore that is rich in calcium monofluorophosphate as carrier, with B216 thixotropic agent (production of Wuhan Shuo Li get scientific & technical corporation) be properties-correcting agent, hexafluorophosphoric acid calcium powder is carried out to modification: the B216 thixotropic agent diluting with dehydrated alcohol after (1:1) is sprayed on hexafluorophosphoric acid calcium powder, and in pulverizer, pulverizing and mixing (ethanol is volatilization automatically in abrasive dust process) B216 consumption is simultaneously 2% of calcium monofluorophosphate total amount.In the end pulverize in abrasive dust process and add in order iron rust changing agent D117 and a small amount of nano silicon oxide and nano-titanium oxide, obtain band rust antirusting powder.
The present invention is a kind of promotes pigment dyestuff to be scattered in the band rust antirusting powder in water-borne coatings: its method is:
(1) the composition weight percent of band rust antirusting powder is:
Component total weight percent is absolutely
(2) thixotropic agent B216 and iron rust changing agent D117 are pressed to 1:1 dilution with dehydrated alcohol respectively;
(3) according to the above ratio hexafluorophosphoric acid calcium powder (moisture is less than 1%) is added in powder modifying machine, start powder modifying machine and stir hexafluorophosphoric acid calcium powder 7 ~ 9min, powder is heated up;
(4) by said ratio and thixotropic agent B216 premix, in temperature, be then under 80-110 ℃ of condition, by modifying machine (1400 revs/min) stirring 10 ~ 15min at a high speed;
(5) according to the above ratio, successively add iron rust changing agent D117, nano silicon oxide and nano-titanium oxide, (1400 revs/min) stirring 10 ~ 30min mixes at a high speed finally; With pulverizer, pulverize together again; In this process, dehydrated alcohol all volatilizees, and prepares the antirust powder of band rust; Smashing fineness >=500 order.
The present invention is a kind of promotes pigment dyestuff to be scattered in the preparation method of the band rust antirusting powder in water-borne coatings, its advantage is: can make organic coloring pigment be evenly dispersed in water-miscible paint and not occur flooding phenomenon, both there is band rust antirust function, and can be applicable to again in oiliness, aqueous antirust paint.
