水性涂料一般包括三种:一种是将水溶性的高分子化合物溶解在水中配制而成,如106涂料是用可溶于水的聚乙烯醇配制而成,但其耐水性较差;另一种是以高分子乳液配制的,我们通常称为“乳胶漆”,它的性能比第一种有所提高;第三种是当今国际流行的水性漆,涂刷后水份蒸发,高分子化合物颗粒与特种助剂相互结合形成高附着力的防水涂膜。 国外的建筑涂料,特别是发达国家的建筑涂料,在其涂料生产总量中所占的比例较大。如美国的建筑涂料占涂料总产量的56％,居首位;曰本的建筑涂料占涂料总产量的34％;我国目前以乳胶漆为主,占70—75％的份额,但因乳胶漆有毒,将会被逐渐淘汰。 随着我国经济的迅速发展,涂料的需求量在逐年增长。预计到2000年需求量将
Waterborne coatings generally include three types: one is formulated by dissolving water-soluble polymer compounds in water. For example, 106 coatings are formulated with water-soluble polyvinyl alcohol, but their water resistance is poor; These are formulated as polymer emulsions. We often refer to them as “latex paints.” Their properties are improved compared to the first. The third type is the internationally popular water-based paints. The moisture evaporates after coating and the polymer compound. Particles and special additives combine to form a high adhesion waterproof coating. Foreign architectural coatings, especially those of developed countries, account for a large proportion of their total paint production. For example, architectural coatings in the United States account for 56% of the total output of paints, ranking the first; Sakamoto’s architectural coatings account for 34% of total paint output; China currently uses latex paints, accounting for 70-75% of the total, but due to latex paints. Toxic, it will be gradually eliminated. With the rapid development of China’s economy, the demand for coatings has increased year by year. It is estimated that by 2000, the demand will be
