▎ 摘　　要

NOVELTY - Anti-corrosion powder coating comprises an outer protective coating and an inner primer. The outer layer protective coating comprises 20-40 pts. wt. thermosetting resin, 1-9 pts. wt. zinc oxide, 1-8 pts. wt. graphene, 1-4 pts. wt. titanium dioxide, 1.5-5 pts. wt. silicon dioxide, 1-5 pts. wt. ultra-fine quartz powder, 1-5 pts. wt. synthetic mica powder, 0.3-2 pts. wt. ultraviolet absorbent, 0.3-1 pts. wt. curing agent, 0.3-2 pts. wt. stabilizing agent, 0.3-1.5 pts. wt. inorganic pigment and 0.3-1.5 pts. wt. coupling agent. The inner layer primer comprises a pipeline inner wall coating and a pipeline outer wall coating. The pipeline inner wall coating includes 25-35 pts. wt. thermoplastic resin, 1-9 pts. wt. antibacterial agent, and 1-5 pts. wt. muscovite powder, 0.5-3 pts. wt. curing agent, 0.5-2 pts. wt. inorganic pigment and 0.5-1.5 pts. wt. coupling agent. USE - The anti-corrosion powder coating is useful for protecting pipeline. ADVANTAGE - The powder coating is reasonable in design, simple and practical, has high weather resistance and corrosion resistance, high leveling, excellent toughness, strong cohesion, and high cost performance, and reduces the overall engineering cycle. DETAILED DESCRIPTION - Anti-corrosion powder coating comprises an outer protective coating and an inner primer. The outer layer protective coating comprises 20-40 pts. wt. thermosetting resin, 1-9 pts. wt. zinc oxide, 1-8 pts. wt. graphene, 1-4 pts. wt. titanium dioxide, 1.5-5 pts. wt. silicon dioxide, 1-5 pts. wt. ultra-fine quartz powder, 1-5 pts. wt. synthetic mica powder, 0.3-2 pts. wt. ultraviolet light absorbent, 0.3-1 pts. wt. curing agent, 0.3-2 pts. wt. stabilizing agent, 0.3-1.5 pts. wt. inorganic pigment and 0.3-1.5 pts. wt. coupling agent. The inner layer primer comprises a pipeline inner wall coating and a pipeline outer wall coating. The pipeline inner wall coating includes 25-35 pts. wt. thermoplastic resin, 1-9 pts. wt. antibacterial agent, and 1-5 pts. wt. muscovite powder, 0.5-3 pts. wt. curing agent, 0.5-2 pts. wt. inorganic pigment and 0.5-1.5 pts. wt. coupling agent. The pipe outer wall coating comprises 20-35 pts. wt. epoxy resin powder, 1-3 pts. wt. muscovite powder, 0.3-1 pts. wt. inorganic pigment, 0.3-1 pts. wt. coupling agent, and 0.5-1.5 pts. wt. curing agent, 0.5-1 pts. wt. stabilizing agent and 1-3 pts. wt. silicon dioxide. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of composition of anti-corrosion powder coating for protecting pipeline (Drawing includes non-English language text).
