The hyperbranched phosphorus-containing epoxy acrylic resin can form an expanded carbon layer after being burnt during burning, so that the hyperbranched phosphorus-containing epoxy acrylic resin plays a role in blocking temperature and oxygen, and the flame retardant property is improved.
2. Inorganic nanoparticles also have a flame-retardant effect, ZnSnO4Zn and Sn ions in the catalyst have the function of catalyzing polymer to form carbon in the polymer combustion process, and SiO2The nano particles can form a barrier layer on the surface of the carbon layer during combustion, and the flame retardant property can be effectively improved under the combined action of the nano particles and the carbon layer. The addition of the inorganic nano-particles also increases the wear resistance and adhesive force of UV glaze.
3. The first photoinitiator and the second photoinitiator have different characteristic absorption wavelengths, and the curing speed is effectively improved through compatibility.
