PROBLEM TO BE SOLVED: To provide a cold insulation material capable of maintaining a material cooled to a lower temperature than the temperature of the use environment in a state of the low temperature and cooling the material to the lower temperature than that of the use environment. SOLUTION: This cold insulation material comprises a porous cured product composed of a cured resin particle assembly prepared by curing an O/W type thermosetting resin aqueous dispersion obtained by mixing a radical- polymerizable thermosetting resin providing a cured product having 1,000 to 1 MPa tensile modulus of elasticity at 5 deg.C in water and uniformly dispersing resin particles in an aqueous phase in the presence of a reinforcing material. The porous cured product has fine open cells. |
