Patent name: Preparation method of cellulose acrylate composite macromolecule degradable material Patent Applicant Chinese Academy of Forestry Science Institute of Forest Chemical Industry Principal Applicant Address 210042, No.16, Suojinwu Village, Nanjing, Jiangsu Province Inventor Chen Riqing; Chu Fuxiang; Wang Chunpeng ;Jin Liwei; Lin Mingtao Application (Patent) No. 200510040286.7 Date of application 2005.05.27 Certification date Approval Notice No. 1693360 Approval announcement date 2005.11.09 Manual CD No. D0545 Main classification number C08L33/04 C08L33/04; C08L1/02; C08F2 /44;C08F2/26;C08F220/14 Subsidiary Original Application No. Priority Abstract A method for preparing a cellulose acrylate composite macromolecule degradable material, the lipophilic powdered cellulose, water, an emulsifier, and a stabilizer Mix with dispersant, add acrylate under stirring, raise temperature, add persulfate initiator, continue heating reaction, drying, wherein emulsifier is sodium dodecyl sulfate, polyoxyethylene nonylphenol ether, One or a mixture of phenol ethoxylates and sodium maleate, 1 to 10% by weight of powdered cellulose; stabilizer Hexadecane, accounting for 1-10%; dispersant is sodium polyacrylate or polyacrylamide, and the weight accounts for 1 to 10% of powdered cellulose; persulfate initiator is sodium persulfate, potassium persulfate or ammonium persulfate. One is 1 to 10% of powdered cellulose; water is 200 to 2000% of powdered cellulose. The invention prepares a new polymer material with excellent comprehensive performance, non-toxic, degradable and environment-friendly, and can be widely applied to many occasions such as plastic film, packaging bag, medicine and the like. Sovereign matter 1, a method for preparing a cellulose acrylate composite macromolecule degradable material, characterized in that oleophilic powdered cellulose, water, an emulsifier, a stabilizing agent and a dispersant are mixed, and powder is added under stirring. Acrylic ester with a cellulose weight of 51% to 1010% is heated to 55-65°C, persulfate initiator is added, and heating is continued to 70-90°C to polymerize cellulose and acrylate into acrylate-embedded fibers. Dispersion, reaction for 2 to 6 hours, drying to form a cellulose-acrylate degradable material, the above emulsifier sodium dodecyl sulfate, polyoxyethylene nonylphenol ether, octylphenol polyoxyethylene ether One or a mixture of sodium maleate, used in an amount of 1 to 10% relative to the weight ratio of powdered cellulose; the stabilizer is n-hexadecane, and the amount used is 1 to 10 in terms of the weight ratio of powdered cellulose. %; dispersant is sodium polyacrylate or polyacrylamide, the amount used is 1 to 10% of the weight ratio of powdered cellulose; persulfate initiator is sodium persulfate, potassium persulfate or ammonium persulfate, The amount used is 1 relative to the weight ratio of powdered cellulose 10%; 200 to 2000% of water relative to the amount of powdered cellulose weight ratio.
