摘要
Abstract
This is an article in the field of mineral processing engineering.Tourmaline has been widely used for its spontaneous polarity,pyroelectric effect,far-infrared radiation and negative-ion release effect.In order to increase its stability in water-based coatings and improve its performance in water-based coatings,in this work,the surface modification of tourmaline with carboxylated nanolocellulose(C-CNF)was studied and optimized.The test results show that the performance of modified tourmaline was optimal while the addition of C-CNF was 2 g,solid-to-liquid ratio 1:5,and reacted 2h at 50 ℃,its turbidity reached 1361 ntu,contact angle to 53°.It was found that C-CNF was successfully grafted to the tourmaline surface by means of characterization of the modified tourmaline,and the dispersion of the modified tourmaline in the aqueous medium was better improved.关键词
