Problems solved by technology

In order to prevent the temperature of the curing material from being too high, the curing system is usually equipped with air cooling or water cooling measures, but the cooling effect is not ideal, and the temperature of the curing furnace will eventually be as high as 80°C

Embodiment Construction

[0027] The specific implementation of the present invention will be further described in detail below in conjunction with the examples.

[0028] The concrete technical index requirement of the embodiment of the present invention is:

[0029] wavelength(nm) Transmittance and reflectivity requirements 320-395 T≥80％ 1000-1500 R≥90％

[0030] The base material is JGS-1 quartz crystal.

[0031] According to technical requirements, when designing the film system, it is necessary to consider not only the high transmission in the ultraviolet band, but also the high reflection in the near-infrared wide spectral band. Glass is used as the substrate, choose Ta which absorbs less in the ultraviolet (320-395nm) and near-infrared (1000-1500nm) bands, and can produce high-reliability films 2 o 5 and SiO 2 The materials are used as high and low refractive index materials respectively. The overall film system adopts a post-cut film structure, and the reflection ba...

Abstract

The invention discloses an ultraviolet-transmission heat-insulation film for ultraviolet curing. The ultraviolet-transmission heat-insulation film takes Ta2O5 and SiO2 as high and low refraction index materials; bandwidth of a reflection band is widened by adopting a post-cutting-off film series structure, and a design method of overlapping of membrane packs with different central wavelengths and alternating refractive index film series; meanwhile, a design result meeting requirements is obtained through matching layer optimizing. In a preparation process of the ultraviolet-transmission heat-insulation film, specific processes including ion assisted deposition, a proper deposition temperature, a deposition speed and the like are adopted. The ultraviolet-transmission heat-insulation film disclosed by the invention can realize high transmission at an ultraviolet waveband of 320nm to 395nm; meanwhile, high reflection at a near-infrared waveband of 1000nm to 1500nm is realized. The ultraviolet-transmission heat-insulation film disclosed by the invention has stable performances and is suitable for regulating and controlling a light spectrum and energy of an ultraviolet curing system so as to reduce the temperature of a working region.

Description

technical field [0001] The present invention relates to optical thin film technology, especially refers to the ultraviolet heat-insulating film for ultraviolet curing system based on quartz glass. By coating multi-layer film on quartz glass, it can realize the wavelength including the required wavelength of ultraviolet curing. The ultraviolet band 320-395nm achieves high transmission, and at the same time realizes high reflection for the near-infrared band 1000-1500nm that carries infrared heat radiation energy. [0002] technical background [0003] UV curing is widely used in printing, coloring, viscose and other industries. Its most notable advantage is that the curing temperature is low, which greatly accelerates the curing speed, and at the same time avoids the adhesion problem caused by solvent-based curing materials due to temperature changes. . The spectral range of ultraviolet light sources used in ultraviolet curing in industrial production is mostly within 300-400...
