摘要： PROBLEM TO BE SOLVED: To improve productivity of a powder coating material, and dispersibility of a resin, a pigment, a curing agent and the like which are raw materials therefor.
SOLUTION: The method for producing the powder coating material comprises mixing the resin, the pigment, the curing agent and the like which are the raw materials for the powder coating material, charging the mixed product in a cavity 1a of a mold 1, and repeatedly adding a load to the mixture by punches 2 and 3 from upper and lower sides, that is, by a bulk mechanical alloying (BMA) method to disperse and mix the raw materials. A melting step by heat becomes unnecessary by dispersing the raw materials by the BMA method to enable constrained conditions of the raw materials therefor to be eliminated. Further, the amount of the curing agent is reduced to make the coating operability excellent by increasing the dispersibility of the curing agent. A low-temperature curable coating material can be designed, and a curing agent which can not be used conventionally can be used to widen the width of selection of the curing agent because the melting step becomes unnecessary.

摘要： PROBLEM TO BE SOLVED: To provide a more accurate and rapid behavior analyzing and evaluating method in relation to a process for forming an organic film on the surface of a metal before the synthesis of an organic film compound and a film forming experiment.
SOLUTION: The potential energies in an atomic or molecular unit of the surface of the metal to be analyzed and the organic film on the surface of the metal are respectively calculated on the basis of a molecular dynamic method by a computer to culculate the most stable structures being the minimum energy values thereof. This calculation is performed using a monomer model as a unit in relation to the organic film and performed in relation to the surface of the metal by constructing the periodic boundary model of a crystal state. Next, the total energy value (=the potential energy value of the periodic boundary model of the surface of the metal-the potential energy value of the monomer model of the organic film) of the most stable structure model wherein the organic film and the periodic boundary model are combined is repeatedly calculated on the basis of molecular kinetics so as to be converged to a definite value to simulate the most stable structure model by the computer. When the total energy value is converged to the definite value, the organic film on the surface of the metal is determined to be stable and the bonded state of the organic film at this time of the behavior reaching the bonded state is analyzed.
