波兰发表了有关铁路机车车辆内墙板表面用油漆腻子的成份和配制方法的一项专利。这种腻子主要用聚辛烷乙稀乳胶液作为粘合剂,白垩、赭石、滑石粉和高岭土作为填料。为了消除脆性、多孔性、与墙板表面连接不好和长期干燥,以及改善磨光时的加工性能,考虑对聚辛烷乙稀进行变性处理,在腻子成分中加入甲醛(0.2～3%),磷酸(0.1～1%,按重量计)和石墨粉(1～7%,按重量计)。研究表明,添加甲醛能提高漆层抗霉菌性能和老化阻
Poland issued a patent on the composition and formulation of paint putty on the interior wall panels of railway rolling stock. This putty mainly uses polyoctane latex as adhesive, chalk, ocher, talcum and kaolin as filler. In order to eliminate brittleness, porosity, poor connection with the wall surface and long-term drying, as well as to improve the processing performance when polished, consider the polyoctane ethylene denatured, putty composition added formaldehyde (0.2 ~ 3%), , Phosphoric acid (0.1 to 1% by weight) and graphite powder (1 to 7% by weight). Research shows that the addition of formaldehyde can improve the anti-fungal properties of the paint and aging resistance
