Complex decomposition additive material having room temperature decomposition properties and pellet for injection molding produced therefrom

The present invention， based on 100 parts by weight of the total room temperature composite decomposition additive composition， 5 to 15 parts by weight of coconut pea; 0.05 to 0.5 parts by weight of wax; 1.0 to 2.0 parts by weight of metal ion salt; 0.5 to 2.0 parts by weight of an organic oxidation initiator; 1.0 to 5.0 parts by weight of an organic acid; 0.01 to 1.0 parts by weight of peroxide; 0.5 to 2.0 parts by weight of a room temperature pyrolysis initiator; 1.0 to 5.0 parts by weight of a redox initiator; It provides a room temperature complex decomposition additive composition comprising 1.0 to 4.0 parts by weight of an antioxidant and a residual amount of a binder resin. The sheet manufactured from the composition for injection molding according to the present invention has excellent tensile strength and elongation that can be applied to various industrial fields such as disposable products， kitchenware， food packaging materials， industrial films and automobile interior materials.
