摘要:
The present invention provides a powder additive for coating materials, plastics, or rubbers comprising particles of a metal or glass, the particles each having a thickness of 0.5 to 5 micrometres, a minor axis/major axis of from 5 to 500 micrometres, an aspect ratio (ratio of the major axis to the thickness) of not less than 5, and a ratio of the minor axis to the major axis, of from 1 to 10, and the particles being leaf-shaped. This powder can readily cause the leafing phenomonon when added to coating materials which are then applied as a coating hence the coating surface can be effectively covered with the powder, so that it can impart superior corrosion resistance and weathering resistance as compared with conventional powders. It can also impart superior electromagnetic shielding properties when added to plastics or rubbers.
摘要(中):
本发明提供一种用于涂覆材料,塑料或橡胶的粉末添加剂,其包括金属或玻璃颗粒,每个颗粒的厚度为0.5至5微米,短轴/长轴为5至500微米, 比例(长轴与厚度的比)不小于5,短轴与长轴的比例为1至10,并且该颗粒是叶形的。 当添加到涂层材料中时,该粉末可以容易地引起翻转现象,然后将其涂覆在涂层上,因此涂层表面可以被粉末有效地覆盖,从而与常规粉末相比,可以赋予优异的耐腐蚀性和耐候性。 当添加到塑料或橡胶中时,它也可以赋予优异的电磁屏蔽性能。
