<p>PROBLEM TO BE SOLVED: To provide a thermosetting resin composition containing a lignin resin, capable of shortening a reaction time during thermal curing, suppressing production of gas during curing, not producing swelling on a molded article, and being almost free from reduction of strength and poor appearance of the molded article, and a method of manufacturing the thermosetting resin composition.SOLUTION: There is provided a thermosetting resin composition which can be obtained by melt-blending a lignin resin, a novolak type phenol resin and an amine-based curing agent and thereafter, thermally curing the melt-blended product. There is provided a method of manufacturing the thermosetting resin composition including: a process 1 of melt-blending a part or all of the lignin resin and the novolak type phenol resin; and further, a process 2 of melt-blending a part or all of the amine-based curing agent and a curing assistant. There is also provided a thermosetting resin composition having 5 to 20 pts.wt. of an amine-based cured product based on 100 pts.wt. of a resin composition and containing hexamethylene tetramine.</p> |
