    摘要: The present invention relates to optionally foamed intumescent masses obtained by reacting(1) polyisocyanates with a mixture containing(2) polyethers having an average OH number of from about 150 to 500 and obtained by the chemical addition of alkylene oxides having an ethylene oxide content of from about 50 to 100% by weight to low molecular weight starters, and/or(3) hydroxyl polyesters having an OH number of from about 100 to 350 obtained by the reaction of aliphatic, cycloaliphatic, araliphatic and aromatic polycarboxylic acids having 2 to 10 carbon atoms with at least two polyols selected from two different groups of the three following groups:(a) hydroxyl compounds with a molecular weight of up to about 200 having more than three OH groups,(b) hydroxyl groups with a molecular weight of up to about 150 having three OH groups, and(c) hydroxyl compounds with a molecular weight of up to about 80 having two OH groups, wherein one of the polyols belongs to group (a), and(4) a phosphate of the melamine phosphate type.The invention additionally relates to the use of the intumescent masses for preparing moulded articles or devices for preventive fire protection.
