ABSTRACT:
A flame-resistant carpet tile having low smoke values and improved flame resistance which carpet tile comprises a primary backing having a fibrous face and a fibrous back, a barrier layer adjacent to fibrous back to an acrylic polymer heavily loaded with a metallic flame-retardant salt filler material which acrylic polymer is compatible with a vinyl chloride polymer layer and a relatively thick vinyl chloride polymer backing layer adhering to the barrier layer.
The method of preparing a flame-resistant carpet tile which comprises pre-coating the back of a carpet with an acrylic polymer latex containing a metallic salt flame-retardant filler material, coating the latex material with a PVC layer, thereafter laying the latex PVC coated carpet into the top surface of a liquid PVC backing layer, heating the laid-in carpet to fuse the PVC layers, cooling the carpet and cutting the carpet into carpet tile.
