Description

technical field [0001] The invention relates to a preparation method and application of a modified montan wax resin, belonging to the technical field of montan wax chemical industry. Background technique [0002] Montan wax resin refers to the general term for resin components in montan wax. In the field of montan wax technology, montan wax is generally divided into three basic components: pure wax (about 60-70%), resin (about 20-30%) and bitumen (about 5-10%) ; Pure wax belongs to the "active ingredient" of montan wax processing and utilization, while resin and bitumen are regarded as "harmful ingredients" that hinder its performance, especially the large content of resin makes its impact particularly prominent; therefore, in order to give full play to lignite The excellent performance of wax usually requires the separation of resin and asphalt components from pure wax components as much as possible, especially the presence or absence of resin has become a key factor. In ...
