| titleOfInvention | Flame retardant polyurethane is composite porous and preparation method thereof |
| abstract | It is composite porous and preparation method thereof the invention discloses a kind of flame retardant polyurethane, include the following steps：The industrial-grade sodium silicate that modulus amount is 2.0~3.5 is diluted with water into the water glass solution that mass percent concentration is 10~30%；It takes calcium chloride to be dissolved in the water and is configured to the calcium chloride solution that mass percent concentration is 0.5~1.5%；By water glass solution and gel triggering agent according to mass ratio 1:1 forms gel stoste after mixing；Open-celled polyurethane foam is immersed in gel stoste vacuum infiltration 1 hour or more in the vacuum chamber that vacuum degree is 0.9atm；It will treated that polyurethane foam is still immersed in gel stoste stands 12~24 hours；Will treated that polyurethane foam spontaneously dries 15 days or more at room temperature, 1~5 hour dry, the cooled to room temperature at 80~110 DEG C of temperature later.Flame retardant polyurethane is composite porous to have good fire protecting performance. |
