Abstract
The invention relates to a special UV type PVD (plating vacuum deposition) primer for improving vibration abrasion resistance. The primer comprises the following components in percentage by weight: 20-40 percent of urethane acrylate, 2-10 percent of modified epoxy acrylate, 2-10 percent of thermoplastic acrylic ester, 1-5 percent of auxiliary resin, 5-20 percent of active diluent, 2-5 percent of photoinitiator, 0.2-0.5 percent of flatting agent and 40-60 percent of diluent. The special UV type PVD primer for improving vibration abrasion resistance has the advantages of low cost, high adhesion, excellent construction performance, good oil attachment and good flexibility, and can be widely applied to PC, ABS/PC, ABS and other materials.
Description
technical field [0001] The invention belongs to the field of ultraviolet curing coatings, and relates to a UV-type PVD primer specially used for vibration and wear resistance, in particular to a UV-type PVD primer specially used for vibration and wear resistance of mobile phones. Background technique [0002] UV vacuum coating coating started at the beginning of this century, which is the perfect combination of UV technology and vacuum coating technology. Compared with other ordinary primers, the vacuum electroplating primer has the advantages of high brightness and good interlayer adhesion with the coating layer. Efficiency has been greatly improved. [0003] Vacuum electroplating is a process of coating metal, metal compound or non-metallic coating on the surface of the plated part by using the migration effect of the electric field in an ultra-low pressure container. It belongs to the physical vapor deposition process (PVD) and is widely used in ABS﹑PE ﹑PP﹑PVC﹑PA﹑PC﹑PMM...
