Plant type soft polyurethane foam for seamless wallpaper
Disclosed plant type soft polyurethane foam for seamless wallpaper is prepared from the following raw materials in parts by weight: 0.07-0.08 part of triethylamine, 0.2-0.26 part of dibutyltin dilaurate, 0.28-0.34 part of water, 56-58 parts of tolylene-2,4-diisocyanate, 0.9-1.1 parts of an organosilicon foam stabiliser, 85-87 parts of polyethylene glycol 400, 9.5-10 parts of glycerin, 18-20 parts of corn straw, 0.6-0.9 part of tetrapod-like zinc oxide whisker, proper amount of a sodium hydroxide solution with the concentration of 0.2%, 9-10 parts of waste and old tyre rubber powder, and 3-3.2 parts of concentrated sulfuric acid . The polyurethane foam employs waste and old tyre rubber powder for modification, and is improved in elasticity, water proofness, heat insulation property and sound insulation property. By using tetrapod-like zinc oxide whisker, the foam is improved in strength and possesses performances of wave absorption, resistance to ageing, resistance to static electricity, resistance to bacteria, and the like.
