[0041] A kind of supercritical foaming nucleating agent, its formula is shown in Table 1.
[0042] The supercritical foaming nucleating agent is prepared by the following method: the organic acid and its derivatives, the inorganic acid and its derivatives and the carbonate in the raw material are ground into a median particle size of 1-20 microns by jet milling Then add polymer and lubricant to pre-disperse the material in the state of ultrafine powder, and get granular supercritical foaming nucleating agent through banburying and granulation.
