Problems solved by technology

Although the above-mentioned dispersant can be used as a dispersion of some solid particles, when in a pigment or coating ink system, because the above-mentioned system usually has a higher solid content, it is required to contain as low a viscosity as possible. The use in the field of pigments and coating inks has great limitations, and most of them have problems such as high viscosity and thixotropy, flocculation and poor fluidity due to poor dispersion

Embodiment 1

[0037] Synthesis of branched polyether-ethyl silicate

[0038] Polyether-ethyl silicate branched product 1

[0039] Under nitrogen protection, 208.33 parts of tetraethyl orthosilicate 28, 2325 parts of polyethylene glycol monomethyl ether (Mn = 750) were added at room temperature In the four-neck flask of the condenser tube of the device, and make it homogenized. Turn on the heating device, set the reaction temperature to 120°C, start stirring at the same time, set the stirring speed to 200rpm, when the reaction mixture reaches about 120°C, the reaction starts, and the transesterification reaction product ethanol is fractionated from the fractionator, collect the fractions, and maintain the temperature for the reaction 1h, then heated the mixture to 160°C, kept at this temperature to collect fractions, maintained the temperature for 1h, finally heated the mixture to 190°C, kept at this temperature to collect fractions, maintained the temperature for 1h, then terminated the re...

[0058] Example 2: Dispersions of particulate solids and their thixotropic properties

[0059] With dispersing aid 1,5,8 (solid content 50%) of the present invention shown in following table 2 or commercially available dispersing aid BYK110 (solid content 50%) respectively with short oil degree alkyd resin (solid content 60%), titanium dioxide in powder form, propylene glycol methyl ether acetate were mixed and dispersed with glass beads in a Dispermat disperser for 1 hour to obtain dispersions 1, 2, 3 and control dispersions of granular solids.

[0063] Note: The viscosity of the dispersion of particulate solids was measured using a Brookfield LVDV-I Prime viscometer using spindle #3.

[0064] The above results show that the solid dispersion of inorganic pigment particles containing the dispersant of the present invention exhibits lower viscosity and thixotropy, and exhibits more excellent dispersibility.

Abstract

The invention relates to an addition compound and a preparation method for the addition compound and a wetting dispersant containing the addition compound used in coating ink. The addition compound isa branched silicon-containing polymer prepared by a monomer mixture through an ester exchange reaction. The branched silicon-containing polymer dispersing auxiliary has a structure as shown in the following formula. An organic silicon component is introduced into the branched polymer, so wetting ability of the dispersant to solid particles is greatly reinforced through a silicon-containing component, and steric hindrance capacity of a branched polyether component to the solid particles is reinforced, an amino residue is bonded and anchored to the surface of the solid particles. While the branched polymer dispersing auxiliary is used for dispersing the solid particles, excellent comprehensive dispersing performance can be provided for an obtained dispersoid.

Description

technical field [0001] The present invention relates to a branched polymer prepared from a monomer mixture by transesterification, which can be used as a wetting and dispersing agent for pigments and fillers. The invention also relates to processes for the preparation of said substances. Background technique [0002] Solid particles are widely used as coloring or filling materials in coatings, adhesives, inks, paints, colorants and other industries. In particular, particulate solids such as pigments and fillers are an important component of coatings. Not only can they impart good hiding power and rich color to the coating, but they can additionally provide coating compositions with improved physical and chemical properties, including improved chemical resistance and thermal stability. [0003] Particulate solids used as pigments or fillers generally have relatively small particle sizes, eg micron or even nanometer particle sizes. If the incorporation of solid particles is...
