Problems solved by technology

However, the energy efficiency of high-pressure mercury lamps and metal halide lamps is low. Due to the short curing time, the input power of ultraviolet bulbs is large, but the output power of ultraviolet rays is small; and in the power of general ultraviolet bulbs, only 20% of the power of ultraviolet bulbs is transformed into ultraviolet lamps. Visible light accounted for 10%, while infrared and thermal energy accounted for 70%, resulting in a large amount of heat energy loss
At the same time, the lifespan of high-pressure mercury lamps is generally 2000-3000 hours, and the lifespan of metal halide lamps is about 1000 hours. The amount of ultraviolet rays will decrease near the later stage, and the equipment needs to be replaced and maintained frequently, which increases production costs.

Abstract

The invention discloses a UV curing coating and an application method thereof. The UV curing coating is prepared from, by weight, 79.2% of polyester acrylate, 5.9% of HDDA, 2.9% of UV curing resin TMPTA, 10% of titanium dioxide, 1% of TPO and 1% of ITX. The UV curing coating can be matched with an infiltration type coating curing device to conduct curing under the wave length of 395 nm, the curing speed is high, energy consumption can be reduced, the energy source can be saved, and the use cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a UV curing coating and an application method thereof. Background technique [0002] At present, since the curing of UV coating needs to absorb ultraviolet light of multiple wavelengths at the same time, it is necessary to use high-pressure mercury lamps and metal halide lamps as light sources. However, the energy efficiency of high-pressure mercury lamps and metal halide lamps is low. Due to the short curing time, the input power of ultraviolet bulbs is large, but the output power of ultraviolet rays is small; and in the power of general ultraviolet bulbs, only 20% of the power of ultraviolet bulbs is transformed into ultraviolet lamps. Visible light Accounted for 10%, while infrared and thermal energy accounted for 70%, resulting in a large amount of heat energy loss. At the same time, the lifespan of high-pressure mercury lamps is generally 2000-3000 hours, and t...
