Abstract：
Experimental light-curing pattern resins were fabricated to produce pattern resin materials with adequate dimensional stability. The light-curing pattern resins consisted of poly(n-butyl methacrylate) or poly(iso-butyl methacrylate) (PiBMA) polymers and methacrylate monomers. The physical properties, amount of residual ash after burning, Vickers hardness, flexural strength, and volumetric polymerization shrinkage of each material were determined. The data obtained for the prepared resins were compared with those of a commercially available pattern resin, Palavit G (PG). A lower amount of residual ash was observed for some of the prepared resins than for PG. The Vickers hardness and flexural strength values of all experimental resins were lower than those of PG. The volumetric polymerization shrinkage of all the experimental resins based on PiBMA was lower than that of PG. These results suggest that acrylic light-curing resin materials based on PiBMA may be useful for patterning and indexing during soldering.
摘要：
制造实验性光固化图案树脂以生产具有足够尺寸稳定性的图案树脂材料。光固化图案树脂由聚(甲基丙烯酸正丁酯)或聚(甲基丙烯酸异丁酯)(PiBMA)聚合物和甲基丙烯酸酯单体组成。物理性质，燃烧后的残余灰分量，维氏硬度,抗弯强度,测定每种材料的体积聚合收缩率。将制备的树脂获得的数据与市售图案树脂的数据进行比较，帕拉维特G（PG）。与PG相比,一些制备的树脂观察到较低量的残余灰分。所有实验树脂的维氏硬度和弯曲强度值均低于PG。所有基于PiBMA的实验树脂的体积聚合收缩率均低于PG。这些结果表明，基于PiBMA的丙烯酸光固化树脂材料可用于焊接过程中的图案化和索引。
