Field of the Invention
The present invention relates to a method of preparing a thermosetting resin composition having an excellent handleability and moldability.
2. Description of the Prior Art
In recent years, an acrylic resin obtained by a reaction of an acrylic monomer and an epoxy compound, and a urethane resin obtained by a reaction of a polyol and an isocyanate compound are increasingly used as an adhesive.
However, the acrylic resin and the urethane resin have a glass transition temperature lower than that of the thermosetting resin, and thus have a disadvantage of low heat resistance.
A method of preparing a thermosetting resin by reacting a polyurethane prepolymer with a polyamine is known as a method for improving the heat resistance of the acrylic resin and the urethane resin. However, when the thermosetting resin is prepared by such a method, a high level of heat resistance can not be achieved.
In order to prevent a reactive group from being hydrolyzed in an alkali solution, it is disclosed in Japanese Laid-Open Patent Application No. 6-296992 that after a polyol and an epoxy compound are mixed, the mixture is reacted with an amine in the presence of a catalyst.
However, when the reaction is conducted at a high temperature, the viscosity of the mixture increases, so that the mixture does not have a desired viscosity. Furthermore, when the viscosity of the mixture is reduced, the reaction temperature must be lowered to maintain the viscosity.eBook Helping People Find Happiness
