| titleOfInvention | A kind of polyurethane foam stabilizer and preparation method |
| abstract | The present invention provides a kind of polyurethane foam stabilizer and preparation method, step includes: silicon oil of low hydrogen content synthesis, the synthesis of unsaturated polyether, it the synthesis of isocyanate-terminated unsaturated polyether and reacts silicon oil of low hydrogen content and isocyanate-terminated unsaturated polyether to obtain polyurethane foam stabilizer, unsaturated end capped polyether makees end-capping reagent using isocyanates in the present invention, its dosage is few, reaction time is short, do not generate abraum salt, stable product quality, it is at low cost, and reactivity is strong, it has excellent performance, solve the problems, such as that existing alkyl-blocked unsaturated polyether sealing end exists, the kind of existing polyurethane foam stabilizer can be enriched by adjusting isocyanate-terminated dose of type. |
