Problems solved by technology
In the production process of home appliances, the components made of fingerprint-resistant boards will not leave fingerprints, sweat stains, affect the appearance, and hinder sales after repeated touches by workers.
[0004] At present, the anti-fingerprint liquid for commercial application generally uses the thermal effect of infrared or hot air to dry the water, and cross-links the hydroxyl groups of the organic resin with the alcohol groups on the surface of the colloidal silica to form a solid film, and there is obvious water evaporation. and volume shrinkage, so it is easy to produce film defects. In addition, the hot air drying equipment occupies a large area and consumes a lot of energy

Abstract
The invention relates to a film forming method of fingerprint-resistant liquid containing double photosensitive resin skeletons. After the fingerprint-resistant liquid is applied, photocuring film forming is realized through twice light irradiation. The method specifically comprises the following steps that 1), the fingerprint-resistant liquid is applied to the surface of a steel plate in a roller applying, spray applying or spin applying mode, and a wet film is formed; and 2), the wet film is irradiated with visible light to enable the photosensitive resin capable of absorbing visible light to be cured in the fingerprint-resistant liquid to be solidified, and net-shaped skeletons are formed, wherein the wet film is irradiated by ultraviolet light, so that the residual fingerprint-resistant liquid is completely solidified to fill pores of the net-shaped skeletons, and a compact fingerprint-resistant leather film is formed. The method has the advantages that a two-step photocuring mode is adopted to replace a traditional hot air drying film forming mode, the film cracking phenomenon in the rapid curing process is avoided, and the process is simple and reasonable. According to the method, the traditional hot air drying mode is replaced, the occupied area of equipment is reduced, the energy utilization rate is increased, and energy consumption is reduced.
Description
technical field [0001] The invention belongs to the field of anti-fingerprint plate production, and in particular relates to a film-forming method of an anti-fingerprint liquid containing double photosensitive resin skeletons. Background technique [0002] Chromium-free hot-dip galvanized anti-fingerprint plate is a product coated with anti-fingerprint coating on cold-rolled galvanized sheet, which has excellent characteristics such as fingerprint resistance, conductivity, and corrosion resistance. It is widely used in high-end home appliance casings. In recent years, the transformation and upgrading of the domestic home appliance industry has provided good opportunities for the development of high-end home appliance steel represented by high-quality chrome-free hot-dip galvanized anti-fingerprint plates. [0003] The origin of anti-fingerprint treatment was originally to meet the user's requirements for the aesthetics of home appliances. This technology achieves the so-cal...
