Title:
PREPARATION METHOD FOR NON-SILICON DEFOAMER REAGENT USED FOR SOLVENT-TYPE COATING AND INK
Document Type and Number:
WIPO Patent Application WO/2012/167650
Kind Code:
A1
Abstract:
Disclosed are non-silicon defoamer reagent used for solvent-type coating and ink and preparation method thereof. The defoamer reagent is prepared from an acrylate monomer, a functional acrylate monomer, an initiator, a solvent and a fumed silica by adding the acrylate monomer, the functional acrylate monomer, the initiator and the solvent to a reaction kettle for polymerization reaction, then mixing the product and the fumed silica. The non-silicon defoamer reagent has excellent foam inhibiting and defoaming effects, and can replace organosilicone defoamers reagent to be used in a system.
