| Title of the article | Study the effect of acid activated kaolin on the properties of waterborne coatings |
| Abstract. | Influence of the kaolin activated by 3 % solution of acetic acid on properties of waterborne styrene – acrylic coatings is considered. It is carried out derivatographic and dispersion analyses of the activated filler for the purpose of definition of possible changes of a chemical composition and dispersion of particles of a kaolin. It is established that acid treatment of filler allows lowering the content of foreign impurity and doesn't influence the mean size of kaolin particles. The analysis of the data obtained after tests in accordance with GOST allowed establishing that filling by the acid activated filler increases value of an indicator of covering ability, water absorption and washability for coatings based on the styrene – acrylic dispersion «Lakroten E-25» brand. However, it should be noted that application as a polymeric matrix of dispersion «Lakroten E-244» brand allows to achieve improvement of coating. The carried-out comparative analysis demands research of the acid-base analyses of the protective coatings filled by acid activated kaolin for the purpose of detailed studying of processes occurring when it forming. |
