<p>Disclosed are an ethylene-propylene-diene monomer grafted maleic anhydride and a preparation method therefor, wherein the ethylene-propylene-diene monomer grafted maleic anhydride comprises the following formulation components in weight percentages: 95% - 97% of ethylene-propylene-diene monomer, 0.1% - 0.2% of an initiator, 1% - 2% of maleic anhydride, 0.8% - 1.5% of a styrene monomer, and 0.2% - 0.5% of hexamethylphosphoric triamine. The present invention uses the ethylene-propylene-diene monomer as a grafting substrate and maleic anhydride as a grafting monomer, and performs the graft under the action of the initiator during melt extrusion. The grafting ratio and the grafting efficiency thereof are high, and the product has little odour, white colour, and is environmentally friendly and safe. The preparation method therefor has a simple process, easily controllable conditions, and is suitable for industrial production.</p> |
