Abstract
Disclosed herein is an adhesive composition which contains specific amounts of (A) an aqueous emulsion, (B) a filler and (C) a resin solution of a resinous tackifier dissolved in a solvent and/or plasticizer. The adhesive composition has a fast setting time in adhesion strength and excellent water-proofness and hence produces superb adhesion force even when applied to a fresh mortar base which has been aged insufficiently.
Claims19
An emulsion adhesive composition for ceramic tiles, which composition comprises:
- (a) an aqueous emulsion selected from a synthetic rubber latex or an acrylic emulsion, said emulsion containing 40-65% by weight of the resin component;
- (b) a filler in an amount of 50-350 parts by weight on a solid basis per 100 parts by weight on a solid basis to the aqueous emulsion;
- and
- (c) a resin solution in an amount of 20-250 parts by weight on a non-volatile component basis per 100 parts by weight on a solid basis of the aqueous emulsion, said resin solution containing a resinous tackifier dissolved in a solvent and/or plasticizer;
- said composition containing 0.5% by weight or less of a surfactant based on the amount of the composition.
An emulsion adhesive composition for ceramic tiles, which composition comprises:
- (a) an aqueous emulsion selected from a synthetic rubber or an acrylic emulsion, said emulsion containing 40-65% by weight of the resin component,
- (b) an inorganic filler selected from calcium carbonate, clay, talc or asbestos in an amount of 50-350 parts by weight on a solid basis per 100 parts by weight on a solid basis for the aqueous emulsion, and
- (c) a resin solution in an amount of 20-250 parts by weight on the non-volatile component basis per 100 parts by weight on a solid basis for the aqueous emulsion, said resin solution containing at least one resinous tackifier selected from rosin, modified rosins and derivatives thereof, polyterpene resins, modified terpenes, aliphatic hydrocarbon resins, aromatic hydrocarbon resins, phenol resins, xylene resins and coumarone-indene resins, and had a sofenting point of 80.degree. C.-130.degree. C., said tackifier being dissolved in a solvent and/or plasticizer, said composition containing 0.5% by weight of less of a surfactant based on the amount of the composition.
