Abstract

A process for incorporating silica fillers in polyurethanes comprises dissolving the silica filler in a fatty glyceride containing hydroxyl groups or a liquid polymeric organic hydroxyl group-containing substance which may contain other groups having active hydrogen atoms or with a prepolymer and thereafter converting the hydroxyl group-containing substance or prepolymer into a polyurethane. Conversion of the propolymers to polyurethanes can be effected by reaction with diols or triols, e.g. ethylene or, propylene glycol, 1:3- or 1:4-butanediol, glycerol or tri-hydroxymethyl propane or with polyamines, e.g. ethylene or hexamethylene diamine, benzidine, dichlorobenzidine, diamino-diphenyl-methane or dichlorodiamino-diphenylmethane. The fillers may be acid, alkaline or neutral silicas and may be obtained artificially, such as products obtained by acidification of sodium or potassium silicates followed by washing and drying. Diatomaceous earths may also be employed. The resulting silicas may be partially hydrated. When the fillers are mixed with the hydroxyl group-containing substances in the liquid condition they swell and dissolve. Lists are given of suitable polyisocyanates, polyethers and reactants from which polyesters can be prepared. Polyesteramides obtained by including, e.g. ethanolamine, propanolamine, ethylene or hexamethylene diamine, diaminodiphenyl-methane and benzidine with the polyester-forming reactants are also suitable. In Example (1) partially hydrated silica is agitated while heating under reduced pressure with a dehydrated polydiethylene glycol/pentaerythritol adipate to give a clear solution. This is cooled to 80 DEG C. and reacted with mixed 2:4- and 2:6-tolylene diisocyanates and after degassing the product is cast into moulds and cured at 110 DEG C. Similarly employed are (2) polyethylene glycol adipate, a polyester from glycol and terephthalic and adipic acids, with mixed isocyanates from an aniline/o-toluidine/formaldehyde condensation product, (3) castor oil and 2:4-tolylene diisocyanate, to give a cold-jointing compound or a heat-resisting cement for electrical components. Specification 733,624 is referred to.
