可剥离水性涂料防护膜虽然成本略高,但因其易施工、易剥离,同时由于黏度大喷涂浪费较小,所以它的综合使用成本并不高。本文引入的新型水性环保防护材料,施工简易,使用成本低,耐盐雾性能达到425h,漆膜色差降低59.8%,光泽度提升13.9%,可在工程机械成品入库和出口海运中推广应用。零部件面漆作为工程机械外观的重要组成部分,不仅对零部件具有重要的防护作用,同时也具有较高的装饰作用。为了保证工程机械外观漆面的丰满度、光泽度,需要在库存、转运过程中防止其出现面漆被磕碰、擦伤、失光、褪色、漆面污染等现象。本文在对面漆防护方 Peelable water-based paint protective film although the cost is slightly higher, but because of its easy construction, easy to peel off, and because the viscosity of the spray less waste, so its comprehensive use of the cost is not high. The new water-based environmental protection material introduced in this paper has the advantages of simple construction, low use cost, salt spray resistance of 425h, color difference of 59.8% and gloss of 13.9%. It can be popularized and applied in finished product storage and export shipping of construction machinery. Spray paint as an important part of the appearance of construction machinery, not only for parts of an important protective effect, but also has a high decorative effect. In order to ensure the appearance of engineering machinery fullness of the paint, gloss, need to prevent the occurrence of stockpiling, transit during the bump was bump, abrasion, loss of gloss, fading, paint pollution and so on. This article is on the top paint protection
