Description
Technical field
The present invention relates to new material the field of chemical synthesis, more particularly to a kind of hydrophobically modified acrylic compounds association thickener
And preparation method thereof.
Background technology
In recent years, water paint substitutes oil paint turns into trend of the times, during due to water paint to storage and construction
Viscosity requirement it is different, it is necessary to come regulation system viscosity and rheological property using thickener, during storage, remain high viscous
Degree, prevents cohesion and the precipitation of pigment, in painting process, by shear shinning, coating is had preferable brushability, brushes
After, lagged by of short duration viscosity, treat film levelling, viscosity recovery.By using thickener, coating height can be balanced and cut
Cut with low sheraing mobile performance, can both avoid storage during deposited phenomenon, also solve the problem that the levelling and stream during coating application
Extension problem, assign the good storage stability of coating and application property.
Polyacrylate-type thickeners are wide in variety because of its various structures, can meet the requirement of various rheological properties, be mesh
Preceding wide variety of a kind of thickener.Such thickener (UIG) is polymerized by 3 kinds or more of monomer at present, main monomer one

Alkali neutralizes, and makes its molecular ionization and produces negative electrical charge along the main chain of polymer, promotes by repelling each other between same sex electric charge
Strand, which stretches opening and forms network structure, reaches thickening effect.Hydrogenbond thickening is that polyacrylic acid molecule combines to form with water
Hydrate molecule, then pass through carboxylate radical as having the nonionic surfactant of 5 or more ethyoxyls to be combined with hydroxyl donor
The same sex electrostatic repulsion of ion, strand are stretched to bar-shaped by helical form, the strand of curling is solved open form in Aquo System
Reticulate structure and reach thickening effect.Inorganic electrolyte mass-energy significantly affects the thickening efficiency of such thickener, and monovalent ion can only
The thickening efficiency of reduction system, divalence or trivalent ion can not only make system thinning, and can be produced not when content is sufficiently high
Insoluble precipitate.Therefore, the electrolyte resistance of polycarboxylic acid thickener is very poor, it can not be answered in fields such as oil exploitations
