EB curing is a form of radiation curing. It is a process of inducing specially prepared one hundred percent reactive liquid to be quickly converted into solid by taking electron beams as radiation sources. The principle is as follows: firstly, high-energy electrons interact with paint or ink molecules to decompose the paint or ink molecules into free radicals; then, the free radical reacts with the C ═ C double bond to form a propagating chain; finally, the chain-extending chain reacts with the rest of the components of the coating or ink, so that the cured coating is crosslinked and the crosslinking density is increased. Due to the high energy of the irradiated electrons, the above reaction is often accompanied by negative reactions such as molecular degradation and molecular ion rearrangement. The EB cured coating thus produces a greater degree of branching and a higher crosslink density.
EB curing requires dedicated curing equipment. The working principle is as follows: after the electrons are emitted from a group of linear cathode plates, the electrons are accelerated by a vertical uniform electric field, and curtain-shaped electron beams are obtained under an accelerator irradiation box. The acceleration voltage is not high (less than 500kV) because the irradiated article is closer to the electric field, but the power is higher because of the large output current. The linear cathode gun is far more compact than scanning type equipment, is easier to install on a production line and is easier to shield.

2. In the present invention, the excimer lamp treatment is used, the depth of penetration of the excimer lamp photons can reach 0.3 μm, the lower surface is still wet and not cured, and the surface free radicals are directly crosslinked, thus increasing the crosslinked area, which is expected to increase the area by 25%.
3. The invention uses the excimer lamp and the accelerating high-energy electron beam process, the surface has no shrinkage, and the finally formed pattern structure is very stable. In addition, a set of equipment is used for processing various patterns, a production mode that the texture of the traditional decorative plate needs to be pressed by a steel plate with prefabricated texture at high temperature is abandoned, the die making cost of the steel plate is reduced, the production cost of the decorative plate is further reduced, and the processing efficiency is improved.
4. The invention is environment-friendly and pollution-free, and does not use toxic substances such as an inducer, thereby avoiding the pollution of food and ensuring the edible health.
5. The decorative plate has good ultraviolet resistance, acid and alkali corrosion resistance, scraping resistance and wear resistance, and meanwhile, the surface patterns are wavy, super-matte and non-reflective, so that light pollution is avoided, and the decorative plate is safe and environment-friendly.
