| Abstract: | Calcined diatomite matting agent was firstly prepared. This matting agent applies in styrene-acrylic emulsion and acrylic emulsion. The whiteness and crystal structure are influenced by calcined temperature and additive. And the granule appearance and granularity distribution can work on extinction capability and extinction effect of high angle, respectively. Crystal product with the whiteness of 90% was synthesized by adding 4wt% NaCl and 7.5wt% amylum. The reaction temperature is 900℃ and the reaction time is 2h. When the granularity distribution mainly focuses on 8μm～25μm, theglossiness of the coating is adjacent with the angles of incidence are 60° and 85°. And the extinction efficiency can reach 51% and 65%, respectively. is |
