Abstract
The invention relates to a composition for making flooring material comprising resin and particles comprising ammonium quaternary salt. The resin is generally an unsaturated polyester resin. The flooring materials, or engineered stone slabs from which the flooring materials or other material can be formed, are generally made from combining the resin, particles, inorganic particulate material and an initiator and allowing the resin to cure. The flooring material composition may be cobalt free. Metal catalysts may be used to cure the resin.
Claims28
A flooring material composition comprising
- (A) an unsaturated polyester resin formulation comprising
- (i) an unsaturated polyester resin component;
- (ii) a metal catalyst capable of catalyzing curing of the unsaturated polyester resin component;

- and
- (iv) optionally, one or more additives selected from the group consisting of pigments, accelerators, co-promoters, dispersing agents, UV absorbers, stabilizers, inhibitors and rheology modifiers;
- (B) particles comprising ammonium quaternary salt;
- (C) an inorganic particulate material;
- and
- (D) an initiator.
A flooring material composition comprising i) a resin selected from the group consisting of vinyl ester resin and epoxy resin and ii) particles comprising ammonium quaternary salt.
A method for the making flooring material comprising the steps of
- (a) preparing a formable composition by mixing
- (A) an unsaturated polyester resin formulation comprising
- (i) an unsaturated polyester resin component;
- (ii) a metal catalyst capable of catalyzing curing of the unsaturated polyester resin component;
- (iii) a quaternary ammonium salt;
- and
- (iv) optionally, one or more additives selected from the group consisting of pigments, accelerators, co-promoters, dispersing agents, UV absorbers, stabilizers, inhibitors and rheology modifiers;
- (B) particles comprising ammonium quaternary salt;
- (C) an inorganic particulate material;
