The invention discloses a method for treating calcite corner waste for plastics. The calcite corner waste is firstly crushed and ground, and then the waste powder is dried to a constant weight to obtain the waste powder; the waste powder is preheated, and then the stirring speed is 100~ Under the condition of 120r/min, firstly add the initiator and mix for 3-5min, then add the premix and immediately place it in a constant temperature box of 120-160℃, react at constant temperature for 20-60min, and then naturally cool to room temperature to obtain the modified powder ; The premix is obtained by mixing vinyl silane coupling agent and vinyl monomer, and the mass ratio of the vinyl silane coupling agent and vinyl monomer is 1: (1-1.5); The plastic product is obtained by injection molding after mixing the plastic powder with the polyethylene resin. The invention recovers the calcite corner waste for modification treatment, improves the compatibility with organic materials such as polyethylene, enables it to be fully integrated with the plastic mixture, and further improves the comprehensive performance of the plastic material. |
