水性木器漆增稠剂的刷涂性能及涂膜性能探讨

Discussion on the Brushability and Film Property of Thickener Water-borne Wood Coating

文章根据不同类型增稠剂的特点以及刷涂施工的流变状态的特点,通过不同增稠剂的搭配来满足水性木器涂料刷涂的施工需求。但是不同的增稠剂的配合方式对水性木器漆漆膜的性能有不同的影响。采用纤维素增稠剂与聚氨酯增稠剂时,影响漆膜的丰满度,但是不影响漆膜的耐水性,而采用丙烯酸增稠剂和聚氨酯和增稠剂时,不影响漆膜的丰满度,但是对漆膜的耐水性有影响。

Based on the character of different type of thickener and requirement of brushing application, combination of different types of thickener could meet the requirement on brushing application. But different combinations had different effects on the properties of coating film. Combination of cellulose thickener and polyurethane thickener was good for water resistance film and bad for build of film. And combination of polyacrylate thickener and polyurethane thickener was good for build and bad for water resistance of film.
