1. a polyurethane foam, it obtains reaction mixture by the following component of mixing and the reaction completing described reaction mixture obtains to obtain polyurethane foam:

  • (a) polyisocyanates,B () has the polymkeric substance of group isocyanic ester to reactive behavior,C () comprises the catalyzer of combinative amine catalyst,(d) phosphoric acid ester, polyphosphate, phosphonic acid ester and/or phosphorous acid ester,E whipping agent that () is moisture, and optionally(f) chain extension agent and/or linking agent, and(h) auxiliary agent and/or additive,The general formula that wherein phosphoric acid ester has is(R 1-O) 3-P=

    O,

    Wherein three R 1part is independently of each other for comprising one or more phenyl, one or more phosphate group (the many alkyl phosphates with oxyethane) or its ester and/or one or more organic moiety being selected from the atom of nitrogen, oxygen, fluorine, chlorine and bromine;

    The general formula that polyphosphate has is–

    [P(O)(O -R

    +
    )-O] n-,

    Wherein n is the integer of 2 to 10000, R '"'"'+for alkali metal cation or ammonium cation;

    The general formula that phosphonic acid ester has is(R 3)(R 2-O) 2-P=

    O,

    Wherein R 2part is independently of each other for comprising one or more organic moiety being selected from the atom of nitrogen, oxygen, fluorine, chlorine and bromine, R 3part is hydrogen or the aromatics with 1 to 10 carbon atom, aliphatic series or cycloaliphatic moiety;

    The general formula that phosphorous acid ester has is(R 4-O) 3-P,

    Wherein R 4part is independently of each other for comprising one or more organic moiety being selected from the atom of nitrogen, oxygen, fluorine, chlorine and bromine.
