Abstract: The microcapsule latex used for coating was prepared using melamine as wall and the air (or carbon dioxide ) as core by combining the orificing method and emulsification condensation technique. The surface structure, stability of microcapsule latex, heat transfer coeffcient as the evaluation basis, the method and process for preparaing microcapsule latex were discussed. Results showed the method is simple and feasible; process for preparaing is economic; the heat insulation property of microcapsule latex is satisfactory.
