Abstract

The invention provides a solvent-free epoxy coating for steel pipe piles. The coating is composed of a main agent and a curing agent. The main agent contains epoxy resin, an active diluent, a filler and an anti-settling agent; and the curing agent contains an epoxy curing agent, a filler, a drying promoter and an anti-settling agent. Compared with traditional solvent based epoxy paint, the solvent-free epoxy coating for steel pipe piles is a solvent-free product, does not contain volatile organic compound, has low odor and little harm to human body, shows its unique security in storage, transportation and usage, eliminates the safety hidden trouble due to aggregation of a large number of harmful solvents, and reduces the harm to physical and mental health of construction workers to the lowest; one-time coating thickness reaches up to above 500 micrometer, so as to reduce the construction frequency, and improves the production efficiency.

Description

technical field [0001] The invention relates to a coating, in particular to a solvent-free epoxy coating for steel pipe piles. Background technique [0002] In the prior art, anti-corrosion coatings are generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, and are an indispensable coating in paint coatings. Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions and protect the service life of non-ferrous metals; A type of anti-corrosion coating that achieves a longer protection period than conventional anti-corrosion coatings. Heavy-duty anti-corrosion coatings are generally used in emerging marine engineering such as offshore facilities, coastal and bay structures, modern transportation such as highway guardrails, bridges and other fields, large industrial enterprises such as food and chemical equipment, inner and outer walls of metal containers, chemicals, steel, etc. field.
