Problems solved by technology

(5) The heat generation is small, the traditional UV light source consumes a lot of power, and the photoelectric conversion efficiency is low. Except about 20% of the energy is converted into ultraviolet light energy, the rest is converted into heat, making the surface temperature of the lamp tube up to 800 ° C. High heat generation, easy to cause damage to the dryer itself and the plate
[0004] For UV light-curing products, simple operation, curable special-shaped parts and special-shaped surfaces, and low equipment purchase and maintenance costs are important problems to be solved. This is due to the large investment in various equipment in traditional UV coating production lines, and product requirements are restricted. The painted piece is flat, and when the UV paint is cured, the intensity of the ultraviolet light will attenuate depending on the distance, resulting in a huge difference in absorbed energy, resulting in uneven curing of the paint film. This is why the mature technology of UV paint is only suitable for flat coating. Hand-held light source curing is particularly important

Description

technical field [0001] The invention relates to the technical field of coating compositions. Background technique [0002] With the further improvement of environmental protection regulations, new water-based coatings with low or zero VOC emissions have become a hot spot in research and development for the purpose of reducing loads. Ultraviolet (UV) curing refers to the process of completely and rapidly transforming a reactive liquid material into a solid using ultraviolet light as an energy source. Compared with the existing UV light source, the advantages of LED-UV light source are mainly reflected in the following aspects. (1) Lower energy consumption and high effective luminous efficiency can reduce energy consumption by 70% to 80%. (2) No ozone is generated during the curing process, and the LED-UV light source does not generate short-wave ultraviolet light, so no ozone is generated during the curing process, and there is no need to install auxiliary devices such as d...
