preparation example Construction

[0051] The preparation method of described graphene-modified plastic printing consumables, comprises the following steps:

[0052] S1: Wash and dry the waste plastics until the water content is ≤0.8%, then mix and pulverize the dried plastics and EPDM grafted with maleic anhydride, and pass through a 200-300 mesh sieve to obtain plastic powder;

[0053] S2: adding a surfactant to the plastic powder prepared in step S1, and activating it for 1.2-1.8 hours at a temperature of 70-74° C. and a rotation speed of 150-180 r / min to obtain an activated plastic powder;

[0054] 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 42-55min to obtain graphene energy powder;

[0055] S4: Under the protection of nitrogen, add the graphene energy powder prepared in step S3, po...

Abstract

The invention discloses a graphene modified plastic printing consuming material and a preparation method thereof. The graphene modified plastic printing consuming material is prepared from the following raw materials: graphene, abandoned plastics, maleic anhydride grafted ethylene propylene terpolymer, polylactic acid, sodium tripolyphosphate, 2-hydroxy-4-octyl diphenylbutanone, butenyl distearamide, glycol monostearate, tributoxy ethyl phosphate, tri(2,4-ditert-butylphenyl) phosphite ester, surface active agent, modifier, generating agent, cross-linking agent, compatilizer, bridging agent, catalyst, plasticizer, dispersing agent, tackifier, curing agent, antioxidant, stabilizer, anti-aging agent, fire retardant and smoke inhibitor. The graphene modified plastic printing consuming material is prepared according to the following steps: cleaning, drying, crushing, activating, mixing and extruding. The abrasive resistance and the tensile strength of the graphene modified plastic printing consuming material prepared according to the invention are obviously better than the abrasive resistance and the tensile strength of the plastic material in the prior art.

Description
