Definitions
- the invention relates to a thickening copolymer and its batch preparation method.
- the preparation method first includes a polymerization reaction of a dihalogen compound and a polyhydroxy monomer and then the reaction with a hydrophobic monoalcohol.
- This copolymer makes it possible to control the viscosity of an aqueous composition.
- thickening agents which are generally water-soluble polymers comprising hydrophobic groups that are often insoluble in water.
- Such macromolecules have an associating character: once introduced into water, the hydrophobic groups are likely to assemble in the form of micellar aggregates. These aggregates are linked together by the hydrophilic parts of the polymers. A three-dimensional network is then formed which causes the viscosity of the medium to increase.
- compositions also comprising a latex-type binder compound
- the thickening agents generally make it possible to develop interactions with the particles of these binder compounds. Such interactions generally make it possible to increase the thickening effect.
- a thickening composition comprising a hydrophilic polymer, advantageously water-soluble, which are flexible and reproducible.
- the term water-soluble polymer means a polymer that is completely miscible with water at a temperature higher than the melting temperature of this polymer.
- aqueous coating compositions and in particular for aqueous paint or varnish compositions, it is necessary to control the viscosity both for low or medium shear gradients and for high shear gradients. Indeed, during its preparation, its storage, its application or its drying, a paint formulation undergoes numerous constraints requiring particularly complex rheological properties.
- pigment particles tend to settle out due to gravity. Stabilizing the dispersion of these pigment particles then requires having a paint formulation whose viscosity is high at very low shear gradients corresponding to the limiting speed of the particles.
- Paint hold is the amount of paint carried away using an application tool, such as a paintbrush, brush or roller for example.
- the tool dipped and then removed from the paint pot carrying a high quantity of paint will avoid having to be refilled more frequently.
- Paint setting is an increasing function of viscosity.
- the calculation of the equivalent shear rate is a function of the paint flow speed for a particular thickness of paint on the tool.
- the paint formulation should therefore also have a high viscosity at low or medium shear gradients.
- a high filling power of the paint must be sought so that when it is applied to a substrate, a significant quantity of paint is deposited during each pass.
- a high filling power then makes it possible to obtain a greater wet film during each pass of the tool.
- High viscosity of the paint formulation must therefore be sought at high shear gradients.
- High viscosity at high shear gradients will also reduce or eliminate the risk of splashes or droplets forming during paint application.
