水乳型芳香涂料的制备 制备水乳型芳香涂料的前提是要制出合格的苯丙乳胶漆,在此基础上再考虑加香和保香问题。 颜料体积浓度(P.V.C)低是获得涂料与涂膜优良性能的条件,但是出现大量泡沫,一是给操作带来不便,二是涂膜出现缩孔,为了消除泡沫,我们用了如下措施: Preparation of Aqueous Emulsion Aromatic Coatings The premise for the preparation of aqueous emulsion aroma coatings is the preparation of qualified styrene-acrylic emulsion paints, on the basis of which the issues of aromatization and preservation of fragrances are again considered. The low pigment volume concentration (P.V.C) is a condition for obtaining good performance of paints and coating films, but there are a lot of foams. First, it causes inconvenience to the operation. Second, shrinkage occurs in the coating film. In order to eliminate foam, we use the following measures:
