Abstract
Building material products, such as, for example, jointing compounds, adhesives, emulsion paints, synthetic plasters, fillers and the like, comprising a mixture of a) at least 10% by weight, in particular 10 to 99% by weight, of a water-soluble natural polymer and derivatives thereof, b) 1 to 89% by weight of an alkali metal salt or ammonium salt of a crosslinked polyacrylate which, if desired, is grafted with a starch, and c) 0 to 60% by weight of a water-soluble alkali metal salt or alkaline earth metal salt of arylsulfonic acid/formaldehyde condensation products or of a sulfo-modified melamine/formaldehyde polycondensation product.
Claims14
A mixture consisting essentially of the following components
- a) at least 10% by weight of
- 1) water-soluble natural polymer or
- 2) a derivative of said water-soluble natural polymer selected from the group consisting of cellulose ethers, starch ethers, carboxymethyl guar, hydroxypropyl guar, carboxymethyl hydroxypropyl guar, and cationized guar.
- b. 1 to 89% by weight of an alkali mend salt or ammonium salt of a crosslinked polyacrylate which polyacrylate is optionally grafted with a starch, and
- c. 5 to 60% by weight of a water-soluble alkali metal salt or alkaline earth metal salt of an arylsulfonic acid/formaldehyde condensation product or of a sulfo-modified melamine/formaldehyde polycondensation product;
- said mixture is used in a building product.
