Moistureproof machine coating and a preparing method thereof

The invention relates to moistureproof machine coating and a preparing method thereof. The coating is prepared from, by weight, 4-9 parts of chlorosulfonated polyethylene, 2-7 parts of trioctyl phosphate, 3-8 parts of talcum powder, 5-9 parts of rosin resin, 1-3 parts of fumed silica, 2-5 parts of hydroxyethyl cellulose, 5-9 parts of acetyl acetate, 3-5 parts of PVC resin and 2-6 parts of zinc oxide. Beneficial effects of the coating and the method are that the coating can effectively have good weatherability, anti-shedding performance, moistureproof performance, acid and alkali resistance and waterproofness in an environment that is moist for long time. 本发明涉及种防潮机械涂料及其制备方法，由如下重量份数的组分制成：氯磺化聚乙烯4-9份、磷酸三辛酯2-7份、滑石粉3-8份、松香树脂5-9份、气相二氧化硅1-3份、羟乙基纤维素2-5份、醋酸乙酯5-9份、PVC树脂粉3-5份和氧化锌2-6份。本发明的有益效果是：可有效的在长期潮湿环境下，具良好的耐候、防涂料脱落、耐潮湿、耐酸碱、耐水的性能。
