一、前言要想向用户提供能够长期保持新车状态的漆膜,就必需防止以酸雨为首、煤烟、花粉、虫害等自然环境造成的侵蚀,通过采用漆膜保护剂可以达到这一目的。过去的漆膜保护剂,有以碳酸钙为主要成分的粉末型、以石蜡为主要成分的油性石蜡型、聚烯烃类薄膜型、与北美的HC规制相对应的水溶型等。但是,以上这些漆膜保护材料都有各自的缺点。粉末型,由于风吹雨打造成保护层消失,所以,保护性能的寿命较短,而且有些间隙部分不易除去。目前为止,主流是油性石蜡型,在自动化喷涂方面较容易施工,是有利的一面,但如果喷涂膜层薄时,容易影响保护性能。而且因为蜡成份是主体,会由于紫外线的氧化劣化作用,而造成保护性能降低,同时除去性能也明显降低。因此,不仅除去作业时间长,而且除去时造成的细伤等,必需经过磨光处理。而且,由于使用溶剂作为除去剂,所以需要排水处理设备。在作业环境方面也存在问题。
First, the foreword In order to provide users with long-term maintenance of the state of the new paint film, it is necessary to prevent acid rain led, soot, pollen, pests and other natural environment caused by erosion, through the use of protective film can achieve this goal. In the past, the protective film-coating agents include powdered calcium carbonate as a main component, oily paraffin waxes containing paraffin as a main component, polyolefin film-based ones, and water-soluble ones corresponding to HC regulations in North America. However, these film protective materials have their own shortcomings. Powder type, the protective layer disappears due to the wind and rain, so the protective properties of the shorter life expectancy, and some of the gap part is not easy to remove. So far, the mainstream is oily paraffin, which is easier to apply in automated painting, but it is an advantage if the sprayed film is thin, which can easily affect the protective properties. Moreover, since the wax component is the main component, the protective performance is reduced due to the oxidative deterioration of the ultraviolet light, and the removal performance is remarkably reduced. Therefore, it is necessary not only to remove the long working time, but also to eliminate the fine scratches caused by the removal and the like, and it must be polished. Moreover, since a solvent is used as a remover, a drainage treatment facility is required. There are also problems with the working environment.
