Flame heating, solidifying technique of solvent-free epoxy paint

Abstract

The invention discloses a flame heating curing technique for coating solidified solventless epoxy paint in the construction of coating the solventless epoxy paint, which relates to the technical field of the piping system and a common technique for coating liquid or other fluids on surfaces. In the technique, a workpiece to be coated is pretreated and qualified, material sheet with antisticking property is adhered and wound on the surface of the workpiece, flame is adopted for heating, and then the antisticking sheet is removed from the surface of the workpiece which is coated with the epoxy paint; after the epoxy paint is coated, the material sheet with antisticking property is again adhered and wound on the surface of the paint, flame is adopted for heating again, after the paint is cured, the adhered and wound material sheet which is antisticking is removed. The invention provides a new flame indirect heating curing technique which only adopts a little antisticking material sheet and a flame generating device to quickly solidify the solventless epoxy paint and to guarantee no coking, flowing and sagging of the solventless epoxy paint. When in construction, the solidification and coating are convenient and economical.

Description

Flame heating curing process of solvent-free epoxy coating Technical field The invention is a flame heating curing process for solvent-free epoxy coatings that is coated and cured during the construction of solvent-free epoxy coatings, and relates to the general process of coating liquid or other fluids on the surface and the technical field of pipeline systems. Background technique At present, solvent-free epoxy coatings are mostly cured without heating. However, in a low temperature environment (below 5 ℃), solvent-free epoxy coatings cannot be cured completely, or when solvent-free epoxy coatings are required to be cured in a short period of time (less than 30 When the curing is completed within minutes), the solvent-free epoxy coating cannot be cured in time. For this reason, people need to use heat curing to accelerate curing. In order to accelerate the curing of the coating, people usually use far-infrared or mid-frequency induction heating. These methods will cause the so...

Problems solved by technology

In order to accelerate the curing of coatings, people usually use far-infrared or medium-frequency induction heating. During the heating process, these methods will cause solvent-free epoxy coatings to flow and hang, destroy the uniformity of coating thickness, and affect the anti-corrosion performance of coatings. , while using far-infrared or medium-frequency induction heating, which requires a lot of equipment. When repairing pipes, these operating methods are low in efficiency, high in cost, and inconvenient
