POLYURETHANE RAW LIQUID CONTAINING BIOMASS POWDER， PREPARATION METHOD THEREFOR AND USE THEREOF

Disclosed in the present invention are a polyurethane raw liquid containing biomass powder， a preparation method therefor and use thereof. The polyurethane raw liquid containing the biomass powder comprises a polyurethane raw liquid A component and a polyurethane raw liquid B component. The polyurethane raw liquid A component contains a polyester polyol， a chain extender， biomass powder， a physical enhancer， a foamer， a foam stabilizer and a catalyst， the physical enhancer being one or more of a glycol amine containing a long chain alkyl branch and a long carbon chain monohydric alcohol. The polyurethane raw liquid B component contains an isocyanate， phosphoric acid and a polyester polyol. The polyurethane raw liquid containing the biomass powder can be used for preparing a high performance polyurethane elastomer. The present invention effectively solves the problem of recycling the biomass powder， and the physical improvement effect of the polyurethane elastomer containing the biomass powder is more obvious.
