本文以特殊异氰酸酯合成的六官能度脂肪族聚氨酯丙烯酸酯,己内基改性二(聚)季戊四醇六丙烯酸酯(DPHA)为主要成膜物质,采用UV固化的方法制备了一种具有超高耐磨性的新型光学薄涂层材料。讨论了光固化树脂、功能单体、光引发剂、助剂及辐照强度对固化涂层性能的影响,通过实验得出最优配方设计,并进行了简单的理论分析。结果表明:实验制备的涂层经0000#钢丝绒测试(1000g,130cycles),硬度4H、透过率99%以上,彩虹纹及表面晶点极少,并具有出色的柔韧性和良好的抗化学性;因此,它是IMD视窗、液晶荧幕、触控面板等产品理想的原材料。
In this paper, hexafunctional aliphatic urethane acrylate and hexahydro-modified di (poly) pentaerythritol hexaacrylate (DPHA) synthesized by special isocyanates were used as the main film-forming materials. A UV- Abrasion of the new optical thin coating material. The influence of light curing resin, functional monomer, photoinitiator, assistant and irradiation intensity on the properties of cured coatings was discussed. The optimal formulation design was obtained through experiments and a simple theoretical analysis was carried out. The results show that the coatings prepared by the experiment are tested by 1000 # steel wool (1000g, 130cycles), the hardness is 4H, the transmittance is more than 99%, the rainbow pattern and the surface have few crystal points, excellent flexibility and good chemical resistance Therefore, it is the ideal raw material for IMD window, LCD screen, touch panel and other products.
