| Title of the article | Modification of styrene-acrylic film former by acid-activated kaolin to improve the protective properties of coatings |
| Abstract. | Results of researches on filling styrene-acrylic dispersions by the acid activated kaolin (AA-kaolin) are given in article. It is established that introduction of the AA-kaolin to coatings on water dispersion of E-21 (40-50 %) and E-25 (25-30 %) promotes some improvement of indicators of covering ability and rinsability – by 1,2 times, in comparison with paint and varnish coatings filled with an initial kaolin. Increase in maintenance of the AA-kaolin in a covering promotes to «braking» of process water- and moisture absorptions when filling over 40-50 %. These results are caused by the fact that, the increased maintenance of the activated filler promotes education in a covering of more dense structure from mineral substances which interferes with penetration of hostile environment. Besides, filling by the AA-kaolin allows to achieve increase in adhesive and cohesive durabilities, at the same time increase in the last causes decrease of the first. |
