Abstract
Synthetic resins are prepared by reacting in an aqueous medium formaldehyde, furfuryl alcohol, urea and thiourea and heating the reaction mixture until an aqueous syrup of the resin is obtained. The quantity of thiourea is preferably between 15 and 30 per cent by weight of the urea. The syrup is incorporated in a floor-covering composition with plasticisers, a filler or mixture of fillers which are free from alkaline constituents and an acid catalyst for the hardening of the resin syrup. In the example, furfuryl alcohol and 40 per cent formaldehyde are refluxed and an aqueous solution of urea and thiourea added. A filler comprising acid-resisting brick dust, silica flour, leather fibre, hardwood sawdust and chromium sesquioxide was combined with a 3 : 1 mixture of finely powdered ammonium chloride and oxalic acid, and a paste made by stirring the filler-catalyst mixture with the resin syrup plasticised with glyceryl sulphide. Other acid catalysts may be used, for example 5 per cent of a 20 per cent solution of sulphuric acid, and other plasticisers, such as glyptal resins or mono ethers of di- or trihydric aliphatic alcohols in which the etherifying group contains not less than four carbon atoms, e.g. monophenyl glyceryl ether.
