在压铸生产中,目前国外普遍采用水基涂料和自动喷涂技术。可提高压铸件表面质量和内部质量,减少工业污染,有利于工人健康和文明生产。我所于1981年开始水基涂料的研究,做过一些探索,现叙述如下: 一、水基涂料中润滑介质 有机硅化合物中由于硅氧键的稳定性和甲基的憎水性,以及甲基硅烷聚合体的结构特点,使甲基硅油具有良好的耐热性,闪点高,不易挥发,粘度温度系数小,耐压缩力大,表面张力小,化学性稳定,电绝缘性能好,对生物体(包括人类)无毒害作用,是较理想的耐高温润滑介质。水基涂料中引进
In die-casting production, water-based paint and automatic spraying technology are widely used abroad. Die casting can improve the surface quality and internal quality, reduce industrial pollution, is conducive to workers’ health and civilized production. I started in 1981, the study of water-based coatings, made some exploration, are described as follows: First, the water-based coatings in the lubricating medium Silicone compounds due to the stability of silicone and methyl hydrophobic, and methyl Structural characteristics of silane polymers, methyl silicone oil has good heat resistance, high flash point, not volatile, viscosity temperature coefficient, compression resistance, surface tension, chemical stability, good electrical insulation, biological Body (including humans) non-toxic effects, is the ideal high temperature lubrication medium.
