Abstract

A process for the production of fire resistant rigid polyurethane foams comprises reacting the unpurified product, containing from 40 to 90% by weight of volatile aromatic diisocyanate, from the phosgenation of an aromatic diamine, with a polyol and a fire retardant agent, in the presence of a blowing agent, using at least one equivalent of isocyanate group per equivalent of active hydrogen. Preferred volatile aromatic diisocyanate components are the products of phosgenation of a tolylene diamine and p,p1 diaminodiphenylmethane, but suitable alternatives are meta- and paraphenylene diisocyanate chlorophenylene diisocyanate 1.5. napththalene diisocyanate and 3,31 - dimethyl - 4,41 - diphenylmethane diisocyanate, from the phosgenation of the corresponding amines. The product of the phosgenation may be used by itself or blended with one or more volatile aromatic diisocyanates from a separate source. The polyols specified are poly-functional polyesters, hydroxyl-ended polyesteramides and polyethers containing a plurality of hydroxyl groups. The fire retardant agents specified are those containing halogen and/or phosphorus such as diallyl styrene phosphonate, diallyl phenyl phosphonate, tetrachlorophthallic acid, dibromophthallic acid, dibromosuccinic acid, tri-(2,3-dibromopropyl) phosphate; tris-(2,3-dichloropropyl) - phosphate, tris - (chloroethyl) phosphate; bis - b - chloroethylvinyl phosphonate, a phosphorus-containing diol, and chlorinated naphthene. Preferred fire-retardant agents are polyfunctional polyethers which contain halogen and/or phosphorus as an integral part of the polyether molecule, e.g. the products of epichlorohydrin and glycerin and sorbitol. Examples of suitable blowing agents are carbon dioxide (produced in situ) and fluorinated aliphatic hydrocarbons and mixtures of these. Other substances such as catalysts, acid dispersing agents, cross-linking agents, auxiliary blowing agents and pigments may also be added. Suitable catalysts are tertiary amines, tertiary amines containing hydroxyl groups, organic tin salts and organo-tin compounds. Examples of suitable dispersing agents are polyethylene phenol ethers, blends of polyalcohol carboxylic acid esters, oil-soluble sulphonates and siloxaneoxyalkylene block copolymers. The examples describe the preparation of fire-resistant rigid foams from phosgenated tolylene diamine and phosgenated p,p1-diaminodiphenylmethane with various polyols and additives and compare their fire-resistance with polyurethane prepared similarly from the corresponding pure diisocyanates.
