Process for producing polyurethane foam, polyurethane foam, and abrasive sheet |
| abstract |
A process for producing a finely cellular polyurethane foam by mixing a first ingredient comprising an isocyanate compound with a second ingredient comprising a compound containing an active hydrogen group, characterized by comprising adding a nonionic silicone surfactant containing no hydroxyl group to at least one of the first and second ingredients in an amount of 0.1 to 5 wt%, excluding 5 wt%, based on the total amount of the first and second ingredients, subsequently agitating the surfactant containing ingredient together with an unreactive gas to disperse the unreactive gas as fine bubbles to prepare a bubble dispersion, and then mixing the bubble dispersion with the remaining ingredient to cure the resultant mixture. Thus, a polyurethane foam having uniform fine cells and a higher hardness than ones having the same density can be produced without using a chemically reactive blowing agent such as water, vaporizable expandable blowing agent such as a fluorocarbon, or other substance such as a finely particular hollow foam or solvent-soluble substance. |
