NOVELTY - Cell regulator comprises 5-25% polyether modified silicone surfactant, 15-35% dimethicone, 1-25% emulsifying agent, 1-10% wax and 40-55% inorganic powder. The emulsifying agent comprises fatty acid polyoxyethylene ester, fatty alcohol polyoxyethylene ether, alkyl aryl sulfonate and/or ester compound. The wax comprises polyethylene wax, polypropylene wax, polytetrafluoroethylene wax, Fischer-Tropsch wax, polyamide wax and/or carnauba wax. USE - The regulator is useful in preparing polyurethane foam (claimed). ADVANTAGE - The cell regulator: prepares polyurethane foam with better density uniformity, supporting performance, air permeability, elasticity, good stability and good supporting performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing cell regulator comprising (a) placing the polyether modified silicone surfactant, emulsifying agent and dimethicone into the reactor, replacing the air in the reactor with nitrogen, keep the system at normal pressure, and stir evenly to form a turbid emulsion and (b) heating up the turbid emulsion to 50-160℃, adding wax and inorganic powder respectively and stirring to obtain the cell regulator; and a polyurethane foam comprising polyol, isocyanate, catalyst and the cell regulator to form by foaming.
