<p>An adhesive for floor coverings containing a) 100 parts by weight of an aqueous polymer dispersion having a solids content of from 30% to 70% by weight of the total weight of said dispersion, the solids content consisting of synthetic resin particles of at least a bimodal particle size distribution wherein the majority of the larger particles is at least twice the size of the majority of the smaller particles and where the majority of the larger particles has a particle site distribution of from 0.5 to 3 .mu. m and the majority of the smaller particles has a particle size distribution of from 0.1 to 1 .mu. m , b) from 30 to 120 parts by weight of a plasticizing mixture of 1) from 45% to 100% by weight of a synthetic resin plasticizer/soft resin mixture with 1 part by weight of said plasticizer per from 1 to 20 parts by weight of said soft resin, 2) from 0 to 20% by weight of at least one organic solvent, and 3) from 0 to 35% by weight of at least one hard resin and c) from 0 to 60% by weight of said adhesive of inert finely-divided fillers. The adhesive is produced by mixing the aqueous polymer dispersion with the plasticizer/soft resin mixture in a ratio of 1:0.3 to 1:1.2 and, optionally, by adding up to 60+++% by weight fillers, related to the total weight. The adhesive is particularly suitable for laying floor coverings of textile or foamed materials.</p> |
