Study On Synthesis And Properties Of Oil Absorption Materials Based On Natural Macromolecule

The new highly oil absorption material development involves the material study, the environmental science as well as chemistry and the biology overlapping international front domain, has the important theory and the practical significance. This dissertation plans through the multi-carbohydrates natural high polymer chemistry modification and its compound, prepares both can highly absorb oil and the biodegradation new oil absorption material, with the aid of FT-IR, SEM studies its composition and the structure, tests its corresponding physics and chemistry performance according to the conventional method, discusses each kind of influence factor, determined the best raw material formula and the preparation condition, form the more complete technical parameter.The dissertation is mainly composed by following three parts:Part I Has the esterification take the methyl benzene sulfonic acid as the catalyst catalysis cellulose and the acetic anhydride to respond that, obtained the acetyl cellulose ester oil absorption material. Around through attribute analysis (FT-IR, SEM), studied the oil absropiton material which the acetyl cellulose ester composition and made results in to blot the fibrous hole structure. The result indicated that, makes the acetyl cellulose highly oil absorption material which results in to have good blots the performance, blots the percentage most to reach as high as 15.96, guarantees the oil rate most to reach as high as 92%.Part II BPO as the initiator initiation cotton fiber and the styrene carries on the stem grafting copolymerization take the benzoyl peroxide, obtained the cellulose and the styrene graft polymer. Through FT-IR, the SEM division analyzes the attribute, has studied the obtained cellulose stem grafting styrene copolymer composition and the structure, obtains its stem grafting rate through the computation size. In the infrared spectrogram the ethenyl characteristic peak had indicated the stem grafting responds prepares successfully. Makes the cellulose stem grafting styrene high oil absorption material which resultsin to use in the vegetable oil absorption, blotted the performance to be good, blots the percentage most to reach as high as 20, guaranteed the oil rate to achieve 93.7%.Part III Carries on the stem grafting copolymerization take the chromic acid as the initiator initiation cotton fiber and the butyl acrylate ester, obtained the cellulose and the butyl acrylate graft polymer. Through FT-IR, the SEM division analyzes the attribute, has studied the obtained cellulose stem grafting butyl acrylate copolymer composition and the structure, obtains its stem grafting rate through the computation size. In the infrared spectrogram the ester base and the ethenyl characteristic peak had indicated the stem grafting responds prepares successfully. Makes the cellulose stem grafting butyl acrylate oil absorption material which results in to use in the vegetable oil absorption, blotted the performance to be good, blots the percentage most to reach as high as 12, guaranteed the oil rate to achieve 80%.
