随着公路建设的不断发展,路面标线作为交通安全设施中的特殊语言,越来越受到重视。目前,我国的路面标线涂料基本上形成以热熔型为主,溶剂型为辅的局面。整个行业年产量达150万吨,但实际年需求量仅15万吨。为改变其环保性、节能性与施工效率等方面的不足,近年来开发应用了水溶型涂料,以其长效、环保、经济的特点显示强劲发展势头。几种路面标线涂料的比较热熔型涂料热熔型涂料以石油树脂或松香树脂为主,施工时需要加热至180℃左右,为刮涂式施工。优点是使用寿命长,可使
With the continuous development of highway construction, pavement marking as a special language in traffic safety facilities has drawn more and more attention. At present, the pavement marking paint in our country basically forms a hot-melt type and a solvent-based one. The entire industry annual output of 1.5 million tons, but the actual annual demand of only 150,000 tons. In order to change its environmental protection, energy saving and construction efficiency and other shortcomings, the development and application of water-soluble paint in recent years, with its long-lasting, environmentally friendly and economical features show strong momentum of development. Several kinds of pavement marking paint hot-melt coating Hot-melt paint to petroleum resin or rosin-based, the construction needs heating to about 180 ℃, for the construction of the scraping coating. The advantage is that it has long service life
