preparation example Construction

[0044] The preparation method of the environmentally friendly wear-resistant plastic material modified by graphene comprises the following steps:

[0045] 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;

[0046] 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;

[0047] 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;

[0048]S4: Under the protection of nitrogen, add the graphene energy powder ...
