Abstract

The invention relates to a processing method and equipment of waste high polymer. Asphalt and waste polymer are mixed and liquefied in a liquefaction reaction kettle under high-temperature inert gases according to the ratio of 3:1 to 4:1, to obtain polymer modified asphalt--plastic asphalt. The reaction kettle adopts the structure that an asphalt inlet is arranged at the top part; an asphalt distributing plate is arranged at the asphalt inlet; a liquefying furnace is arranged at the middle part of the kettle; heating wires are arranged inside the kettle; a plastic asphalt outlet is arranged at the lower part of the kettle; and a plastic asphalt distributing plate and a stirrer are arranged at the upper part of the outlet. The waste high polymer liquefaction reaction kettle and the processing method change the usage of waste plastic, the waste plastic in electronic waste is directly liquefied under high temperature and high pressure without sorting and cleaning, and then is prepared into the plastic asphalt; compared with the plain asphalt, the plastic asphalt has better flow resistance, skid prevention, abrasion resistance, cold cracking reducing and better drainage performance; and the technological processes are reduced, and the regeneration and utilization of the resource are realized.

Description

technical field [0001] The utility model relates to a method and equipment for treating waste high molecular polymers. Background technique [0002] At present, the international and domestic methods of recycling high molecular polymers in electronic waste are physical methods: these polymers are divided into three types (PU, PP, ABS) and sold to related companies. Combined with pressure molding, filling, extrusion molding and other methods of reuse, this method is simple and mature; but the recovered materials are suitable for low-end products, and aging and elimination are faster. There are also chemical methods for recovery: chemical methods are divided into alcoholysis, hydrolysis, alkali hydrolysis, pyrolysis and other methods. There are many alcoholysis methods, among which small molecule alkyl glycols are used as the main alcoholysis agent. The reaction temperature is controlled at 150-250° C. for alcoholysis reaction for 15 hours to obtain a mixture of regenerated ...
