INTRODUCTION
One of the main methods for the industrial production
of coloring preparations based on resins and
plasticizers used for dyeing polymeric materials is the
flushing process (water breaking), which allows direct
transfer of pigments from an aqueous medium into an
organic binder medium, bypassing intermediate drying
and grinding. At the same time, a high dispersion of
primary particles in the finished composition is
maintained.
It is known that the flashing process is based on the
phase transition of the pigment from the aqueous
phase to the organic binder under the following
condition: σ p .v
˃
σ
p.o.s. _ where
σ
a.c. - surface
tension at the pigment-water interface,
σ
p.o.s -
surface tension at the pigment-organic binder
interface [1].
To change the interfacial interaction, surfactants are
used, which are introduced for this purpose into the
process of pigment synthesis, at the last stage of
washing them from water-soluble salts, or in the
process of flushing [2].
The purpose of our work was to identify the degree of
influence of a number of surfactants introduced into
the aqueous pigment paste on the completeness and
rate of water separation in the preparation of colored
preparations based on dibutyl phthalate and
unsaturated polyester resin NPS 609-21M.
Since the question of the nature of the most effective
surfactants used in the flushing process is not entirely
clear in the literature [3, 4], we turned to surfactants of
various types.
Fatty acid monoethanolamides , lauryl pyridinium
sulfate (LPS), triethanolamine salt of lauryl sulfate (
TEASLS).
Zh , inorganic pigment titanium dioxide (rutile) were
studied as organic dyes .
The listed dyes in the form of aqueous pastes were
homogenized in a Werner-Pfleider type laboratory
mixer (Fig. 1) in the presence of surfactants in an
amount of 1-2.0 wt . % of the dye at a temperature of 25
° for 30 minutes (depending on the reaction of the
aqueous dye paste with a 25% solution of ammonia or
acetic acid, the pH value of the reaction medium was
set in the range of 6.5-7.5).

Fig-1. General view of the Warner -P Flyder type mixer.
The process of water beating successfully develops
under the condition of complete wetting of the
pigment particles with an organic binder and some
excess of it up to the “ saturation point”. Based on this
premise, the amount of binder required to cut off
water (in our case, dibutyl phthalate or unsaturated
polyester resin NPS 609-21M) was determined similarly
to oil absorption of I and II types. The oil absorption of
the second kind is determined upon receipt of a drop-
liquid system. The separated water was drained, the
mixer was sealed, with a discharge of 200-400 mm Hg.
Art. and heating up to 70-75° C by running hot water
into the jacket of the apparatus, the residual moisture
was removed to the presence of its traces. The finished
preparation was obtained by diluting a thick paste with
a binder - in the case of dibutyl phthalate, to a pigment
content of 40 wt . %, unsaturated polyester resin HPO
609-21M for organic dyes - 10 wt.%, for titanium dioxide
20 wt.%.
Analysis of the data obtained (Table 1) shows that the
introduction of the considered surfactants at the stage
of mixing aqueous pastes of vat dyes

with dibutyl phthalate or unsaturated polyester resin H
PS 609-21M does not intensify the flushing process.
With the use of LPS in the case of titanium dioxide, the
time of water distillation is reduced from 20 to 1.5 min
with a decrease in residual moisture by almost a factor
of 2 (from 20 to 11%).
For an unambiguous explanation of the observed
picture, we determined the relative change in the
nature of the surface of the dyes when modifying their
surfactants by determining the wettability with water.
Under the conditions under consideration, not only did
the formation of a chemisorption hydrophobic layer on
the surface of the solid phase, which promotes
flushing, occur, but in the case of the use of a
bifunctional surfactant-TEASLS, some of the layer is
observed. hydrophilization of organic dyes (tab.-2)
According to the method described in the literature
[5], we measured the impregnation time of 1 g of the
powder of the initial vat dyes Bordeaux and bright
green G and with the addition of surfactants in the
same quantities as during the flashing process .

Thus, the results obtained confirm that the presence of
LPS macromolecules on the surface of polar rutile,
which contributes to a decrease in the polarity of T iO
2 , led to a significant intensification of water beating
by unsaturated polyester resin HPS 609-21M.
