The Synthesis And Utility Of Siliconge Foam Stabilizer

Foam stabilizers, also known as foam stabilizer, mainly used in polyurethanefoamprocess,wherein an additive one.This article uses the alcohol-modified platinum catalyst briefly its catalytic performancecompared with traditional speier catalyst, results show that the than speier catalyst has ahigher activity compared，and explore punishments for such catalyst.Then telomerization synthesis of hydrogen silicone oil, hydrogen content,viscosity,crosslinked case was discussed on the synthesis of hydrogen silicone conditions, such aswater content, the reaction temperature, the amount of sulfuric acid, the reaction timeobtained at room temperature,2%by mass of concentrated sulfuric acid, before the reactionand dehydration treatment, the reaction of4hours can be obtained relatively satisfied withthe hydrogen-containing silicone oil.By synthetic alcohol platinum catalyst and synthesis of hydrogen silicone oil, coupledwith commercially available the allyl polyether synthesis of polyether silicone oil, the use ofsingle-factor method examines the various reaction conditions of low hydrogen silicone andallylpoly ether hydrosilylation reaction to obtain the optimum reaction conditions, the amountof30ppm of catalyst, the reaction temperature is120℃, the reaction time was4hours,solvent-free,transparent silicone polyether.Own synthesis of polyether silicone oil as foam stabilizers were discussed the siliconepolyether siloxane and polyether chain section to find out the best ratio of dimethyl siloxanechain80, methyl siloxane foam13when the best results.Subsequently also discussed the offoam stabilizers quality foam effect.Through this series of work, to identify the soft foam foam stabilizers, foaming effect.
