preparation example Construction

[0076] The preparation method of described graphene printing material, comprises the following steps:

[0077] S1: Purchase two-dimensional graphene raw materials on the market, and prepare primary graphene powder through special treatment;

[0078] S2: Use a hard plastic crusher to initially crush waste plastics, and then use an intermittent stirring plastic washing machine to thoroughly clean the crushed waste plastics to remove surface dirt. After natural drying and selection, selected plastics are obtained;

[0079] S3: Put the selected plastic prepared in step S2 in a nitrogen or dry ice low-temperature pulverizer, pulverize the plastic at a temperature of -90--110°C for 2-3 hours, and obtain 400-600 mesh plastic fine particles after sieving ;

[0080] S4: Add polylactic acid, potassium tripolyphosphate, adipate, and specific synthetic agents to the primary graphene powder obtained in step S1 and the plastic fine particles obtained in step S3, and heat up to 196-225° C. ...
