【Abstract】 In order to better utilize the lignite wax resources, the morphological centrifugal stability, salt resistance, acid and alkali resistance, thermal decomposition, bacteriostatic and application properties of three composite wax emulsions were analyzed. The particles of the wax emulsions were spherical with particle sizes ranging from 50 nm to 250 nm. The wax emulsions had good centrifugal stability, and the delamination rate was less than 3% at 6 000 r·min^-1 for 30 min. The wax emulsion had good salt and alkali resistance, and had good stability under the conditions of salt concentration less than 100 mmol·L^-1 and pH less than 11. The decomposition temperature of the main substances in the emulsion was from 250 ℃ to 400 ℃. And it had good antibacterial property to E.coli. Applying it on the surface of leather could make the leather get good color change performance, enhance its brightness and handfeel, and had certain covering property. The excellent performance of lignite wax emulsion makes it have a broad application prospect.更多还原
