光敏涂料及其在木材涂装中的应用试验

进行了合成丙烯酸环氧酯树脂、安息香乙醚的试验,确定了合成的条件。用反应性予聚物丙烯酸环氧酯树脂、活性稀释剂苯乙烯、光敏剂安息香乙醚和其他添加剂配成了光敏涂料,并用此涂料加上适当的填料和颜料配成了光敏腻子。用光敏腻子和光敏涂料对木家俱、人造板进行了涂装试验,试验证明此两种材料具有固化快、涂膜理化性能好等优点。试验也确定了薄木装饰纤维板的涂装工艺,为生产性大车间的设计提供了工艺路线和基本工艺数据。使用光敏涂料的经济效果与现用的高级木家俱漆硝基木器清漆和不饱和聚酯漆相比较是合理的。

Preparation of a UV-curable Coating and Its Application in Wood Finishing

Experiments in syethesizing acrylic epoxy and benzoin ethyl ether were carried out, and the conditions for synthesizing, them found out. With this reactionary prepolymer acrylic epoxy, and this sensitive agent benzoin ethyl ether together with an activated thinner siyrone, and other additives, UV-curable coating was made up. And, by adding proper packings and pigments to this coating, UV-curable filler was composed. Experiments in coating wooden furnitures and wood-based panels with both the UV-curable filler and the UV-curable coating were carried out.The experiments proved that the two materials possessed the advantage of curing fast with the film being of excellent physical and chemical properties. A coating technology for veneered fibrebcard was also found out, thus supplying the designing of the workshop with technological process and essential technological data. The experiments also preved that using UV-curable coating would lead to more economical results than using uitrceeltelese lacquer or unsa turated polyester Lacquer.
