Definitions
- the present invention is a new additive for construction chemical applications, consisting of a core component A) and applied to this shell component B).
- modified cellulose ether The almost most important role in such organic modifications plays the so-called modified cellulose ether, which can be summarized under this term a large variety of multi-component systems. Through the use of such cellulose ethers numerous building material properties can be specifically adapted to the particular application.
- European Patent EP 053 768 B1 describes in detail the composition of the named components and their effects on the adhesion tendency of corresponding building material systems.
- additive combinations of water-soluble cellulose ethers and their derivatives, polyacrylamide, alkali metal or ammonium salts of crosslinked polyacrylates optionally grafted with starch are used commonly referred to as superabsorbents (SAB);
- starch ethers and additions of alkali metal, alkaline earth metal or ammonium salts of condensation products of naphthalenesulfonic acid or phenolsulfonic acid with formaldehyde or with sulfonic acid-modified polycondensation products of melamine and formaldehyde are also suitable.
- this multicomponent additive contains the starch ethers together with polyacrylamide as a synthetic polymer compound in admixture with water-soluble mixed substituted cellulose ethers which, in addition to hydroxyethyl substituents, have 3-alkoxy-2-hydroxypropyl radicals having 2 to 6 carbon atoms in the alkoxy group.
- water-soluble mixed substituted cellulose ethers which, in addition to hydroxyethyl substituents, have 3-alkoxy-2-hydroxypropyl radicals having 2 to 6 carbon atoms in the alkoxy group.
