Abstract

The invention relates to a novel polyethylene powder coating, and especially relates to the preparation of the polyethylene powder coating compositely modified by carbon nanofibers and epoxy resin. The polyethylene powder coating of the invention comprises 100 parts of linear low density polyethylene (PE), 5-10 parts of carbon nanofibers, 10-15 parts of epoxy resin, 5-20 parts of micron-grade inorganic fillers, 1-3 parts of silane coupling agents, and 1-5 parts of powder additives. The preparation employs a parallel-exhausting twin-screw extruder, a high-speed mixer, and a high-speed pulverizer. The obtained product has high mechanical strength, good impact resistance, and excellent adhesion to metal substrates.

Description

1. Technical field

[0001] The invention relates to a novel polyethylene powder coating, in particular to the preparation of a composite modified polyethylene powder coating with carbon nanofibers and epoxy resin. 2. Background technology

[0002] Polyethylene powder coating is a thermoplastic powder coating made of polyethylene (PE) as the main raw material, adding various additives, mixing, pulverizing and grinding. The polyethylene powder coating film has excellent water resistance, acid and alkali resistance, chemical resistance, water absorption below 0.001%, good low temperature resistance, and no cracking at -40°C for more than 400 hours. Polyethylene powder coating endows the coating film with excellent leveling, soft texture and waxy feeling, and has been widely used in chemical equipment, chemical pipelines, chemical storage tanks, plates, wires, mechanical parts, light industrial appliances and food industries, etc. aspect. However, ordinary polyethylene powder h...
