POWDER REDISPERSIBLE IN WATER, PROCESS FOR PRODUCTION THEREOF AND USE THEREOF |
摘要 |
The present invention relates to a process for the production of powders redispersible in water comprising an organic component and a water-soluble organic polymeric protective colloid. The organic component is dispersed and stabilized with the protective colloid in water to form a stable dispersion which is dried to form the powder redispersible in water. The organic component comprises abietic acid, sylvic acid, neoabietic acid, levopinaric acid, pimaric acid, isopimaric acid and/or palustric acid and/or their derivatives. The water-soluble organic polymeric protective colloid comprises synthetic protective colloids and naturally and/or synthetically produced biopolymer which can be synthetically modified. The obtained powder reduces efflorescence in hydraulically set systems.
