目前在建筑工程中以使用低档油脂型涂料为主,如厚漆(铅油)、调合漆及醇酸磁漆(多为罩面用)等。低档油脂型涂料具有施工期长、不安全、有微毒、漆质较差等缺点。制造低档油脂型涂料需用桐油、植物油,目前桐油产量低、价格较高,大量供应十分困难。为使我国涂料工业向节能、防污染方向发展,生产水溶性涂料是一条重要途径。水乳胶涂料是水溶性涂料两大类之一,大部属于热塑型,它的特点是施工期短,
At present, the use of low-grade oil-based paints, such as thick lacquer (lead oil), blending lacquer, and alkyd enamel (mostly for overcoats), is currently used in construction projects. Low-grade grease type coatings have the disadvantages of long construction period, insecurity, micro-toxicity, and poor paint quality. The production of low-grade oil-based paints requires the use of tung oil and vegetable oil. Currently, the tung oil has low output and high prices, and it is difficult to supply large quantities of oil. In order to make the paint industry in China develop toward energy conservation and pollution prevention, the production of water-soluble coatings is an important approach. Water emulsion paint is one of the two major categories of water-soluble paints. Most of them are thermoplastic type. Its characteristics are short construction period.
