The invention relates to a drag-reducing abrasion-resisting solventless
coating for a pipeline as well as a preparation method and application thereof. The drag-reducing abrasion-resisting solventless
coating contains an A component and a B component, wherein the
mass percentage of raw materials is as follows: the A component includes the following materials in percentage by weight: 30%-40% of
epoxy resin, 5%-10% of
toughening resin, 4%-8% of active diluents, 4%-8% of
zinc phosphate, 0.2%-0.5% of
levelling agents, 0.2%-0.5% of
defoaming agents, 0.4%-0.8% of dispersing agents, 0.2%-1.0% of anti-
settling thickening agents, 8%-20% of
ferric oxide red
powder, 5%-15% of
aluminium triphosphate and 5%-15% of white pottery
magnetic powder; the B component includes the following materials in percentage by weight: 5%-20% of modified amine and 2%-10% of modified
polyamide; and the A component and the B component are matched for use according to the
mass ratio of 3-5:1. The drag-reducing abrasion-resisting solventless
coating is prepared through material blending, dispersion,
grinding,
filtration and packaging and can be applied in delivery pipelines of oil and natural gases. The drag-reducing abrasion-resisting solventless coating does not contain
volatile solvents and has the advantages of good
adhesive force, flexibility, salt spray resistance and
solvent resistant property, smooth coating surface, good drag-reducing abrasion-resisting effect, convenient construction,
resource saving and good popularization and application prospect.
