Abstract

Bentonite need to be organiced before it is used in plastics.The raw bentonite comes from Weifang,Shandong.The high-purity bentonite was obtained by wet method and then treated with sodium carbonate.At last the organo bentonite was produced by different organic modifier.The results showed that Na-bentonite could be produced from wet purified bentonite by incubating with 10% Na2CO3 for 2h at 65℃.After treated with 20% Alkyl dimethyl benzyl ammonium chloride and caprolactam compound modification agent at 70℃ and pH value is 6 for 1.5h,the organic bentonite with the layer sacing of 2.44nm was obtained.
