Method for producing extruded polystyrene resin foam board and extruded polystyrene resin foam board |
| abstract |
PROBLEM TO BE SOLVED: To provide a foam produced by using isobutane having an ozone depletion potential of 0 and a low global warming potential as a blowing agent in view of the drawbacks of a conventional extruded heat-insulated foamed polystyrene resin foam plate. Provided is a polystyrene resin extruded heat insulating foam board which is a board and has excellent flame retardancy and small thermal conductivity. SOLUTION: The method for producing an extruded polystyrene resin foam board of the present invention is a foamable molten resin mixture obtained by heating a polystyrene resin in an extruder and kneading it together with a foaming agent, a flame retardant and a cell regulator. Is extruded into a low-pressure region through a die attached to the tip of an extruder, wherein the foaming agent contains isobutane and has a content of 25% by weight or more and 65% by weight or less based on the total amount of the foaming agent. , 5% to 70% by weight, based on the total amount of the blowing agent, of dimethyl ether, 5% to 55% by weight of carbon dioxide, based on the total amount of the blowing agent, and total weight of the blowing agent. 0 to 25% by weight of other blowing agents are used. |
