The invention discloses modified plastic and a processing method for manufacturing a game console handle by using the plastic. The modified plastic is prepared from 40 parts by weight of polypropylene, 25 parts by weight of polyvinyl chloride powder, 30 parts by weight of ceramic powder, 6 parts by weight of polyethylene octene co-elastomer, 4 parts by weight of plasticizer, 4 parts by weight of foaming agent, 4 parts by weight of corrosion inhibitor, 4 parts by weight of chelating agent and 6 parts by weight of peppermint oil. According to the modified plastic, the ceramic powder, the plasticizer, the corrosion inhibitor, the chelating agent, the peppermint oil and other components are added, compared with traditional plastic manufacturing, the modified plastic is smoother in touch feeling, sweat stains and peppermint oil are not prone to adhering, the touch feeling of the hand is cool, hand sweat can be reduced in cooperation with the strip-shaped grooves in the handle and the cooling factors in the strip-shaped grooves, and the problems that the existing game console handle is made of traditional plastic, hand sweat is generated when a user holds the game console handle to play games, the grip of the game console handle becomes sticky, the operation is influenced, and the game experience of game enthusiasts cannot be met are solved.
