Problems solved by technology

[0004] Existing UV-curable coatings have a long-standing shortcoming that is difficult to overcome: due to the special curing method of UV-curable coatings, the curing process is completed within a few seconds, and the huge shrinkage makes thick coating impossible, which restricts the use in the field of anti-corrosion
UV-curable coatings have not been applied in the field of anti-corrosion technology, especially in the field of heavy-duty anti-corrosion. This technical problem has not been solved for a long time.

Abstract

The invention relates to an ultraviolet curing paint, and concretely relates to an automatically sprayed ultraviolet curing paint and a preparation method thereof. A disadvantage of present ultraviolet curing paints is that: the curing process is completed in several seconds, and the large contraction makes the formation of the thick coating to be impossible, so the usage of the paints in the anticorrosion field is restricted. The ultraviolet curing paint comprises the following substances, by weight, 100 parts of an oligomer, 20-50 parts of a monomer, 10-30 parts of a coupling agent, 2-10 parts of an acid anhydride, 1-2 parts of a mixed assistant, 10-30 parts of nanometer silica, 3-10 parts of a photoinitiator, 80-200 parts of a solvent and 100-200 parts of a propellent. The ultraviolet curing paint of the invention, which allows a technical problem of ultraviolet curing paints for the equipment anticorrosion to be solved, has the advantages of good anticorrosion effect, convenient construction, no need of compressed air, realization of the automatic spray, simple preparation method, safety, no pollution, fast curing speed, high production efficiency, high film quality, and excellent coating performance.
