| Faced with the increasingly scarce fossil resources and its serious environmental pollution, people want replace it with renewable biomass resources. As people valued health, people found unsaturated acid contained in the camellia. When one ton of camellia produced, there has been nine ton of leftovers(YJS).The biorefinery technology takes full consideration of the idea as much as possible that each main components of the raw material are converted to different products, expecting to make efficient and full use of the whole components of the material and maximize the value of the products. To overcome the shortcomings of AKD emulsion:easily hydrolyzed, low filler retention rate, sizing in high cost, and so on.This paper made preliminary exploration to emulsion technology, applied biomass surfactants into emulsified paraffin by focusing on AKD emulsion emulsifiers and paraffinemulsifiers. Opened up a high value utilization way of YJS.Considered the surface activity of the extracted liquids from camellia meal, all components are extracted integratedly by carrying biorefining towards the camellia dregs to give the novel biomass surfactant. Firstly, the camellia meal is extracted to study the best extraction conditions, and investigated the surface activity of the extracted liquids from camellia meal; Secondly, we identified the best complex commodity emulsified by surfactants AKD, which can remix with extracted liquids, to get the AKD emulsion of low hydrolysis rate, high efficiency and low cost of sizing. Thirdly, according to the domestic direction of development on AKD emulsion technology,self-made polymerizable emulsifiers synthesized a series of AKD special polymeric emulsifiers and investigated how the structure of polymeric emulsifier influences the performance of AKD emulsion. Finally, the extracted liquids from camellia dregs are used in the emulsification process of paraffin emulsion to give the paraffin emulsion of good stability and good film-forming ability. |
