Abstract

The invention provides photocurable silver powder paint, which is composed of the following components (by weight): 50-70 parts of photocurable resin, 10-15 parts of a photocurable active monomer, 0.5-5 parts of pyrolysis type visible light initiator, 1-3 parts of a hydrogen abstraction type visible light initiator, 1-5 parts of a photosensitizer, 4-7 parts of a silver powder orientation agent, 0.1-0.5 part of a wetting agent, 0.1-0. 5 part of an antifoaming agent, 0.5-2 parts of a rheological additive, 3-6 parts of silver powder, and 0.1-0.5 part of a dispersing agent. The invention also provides a method for preparing the above photocurable silver powder paint. The coating of the powder paint can be cured by the use of visible light with a wavelength of 405 nm. The curing speed is fast;energy consumption is low; environment is protected and VOC is low; construction efficiency is high; and construction cost is low. In addition, the coating has excellent mechanical properties, good weather resistance and scratch resistance.

Description

technical field [0001] The invention relates to a photocurable silver powder paint and a preparation method thereof. Background technique [0002] Silver powder paint has a good metallic surface gloss and has been widely used. [0003] Although the existing silver powder paint is a water-based system, it uses heat curing, the curing speed is slow, the temperature and humidity of the construction are high, and there is a large amount of VOC emissions. The construction will cause serious air pollution and high energy consumption. And the surface properties of the cured coating film are poor. Contents of the invention [0004] The object of the present invention is to provide a light-cured silver powder paint and its preparation method. The silver powder paint of the present invention can use visible light with a wavelength of 405nm to cure the coating, with fast curing speed, low energy consumption, environmental protection, low VOC, and high construction efficiency. , The...
