preparation example Construction

[0059] The preparation method of the graphene-modified heat dissipation material for printing comprises the following steps:

[0060] S1: crush the PET resin and glycol ether acetate and pass through a 200-300 mesh sieve to obtain mixed resin powder;

[0061] S2: adding a surfactant to the mixed resin powder prepared in step S1, and activating it for 1-1.3 hours at a temperature of 68-72° C. and a rotational speed of 150-180 r / min to prepare an activated mixed resin powder;

[0062] S3: Pulverize the graphene and pass it through a 200-300 mesh sieve to obtain a powder. The obtained powder is under a magnetic field strength of 7000-8200GS, an ultrasonic power of 520-650W, a temperature of 52-56°C, and a rotation speed of 200-300r / min. , stirring for 40-50min to obtain graphene energy powder;

[0063] S4: Under the protection of nitrogen, add the graphene energy powder prepared in step S3, polylactic acid, sodium tripolyphosphate, chloropropyl styrene, maleic anhydride grafted ...
