| Fluorine-containing compounds with hydropHobic oleopHobic location, good heat resistance, chemical stability, low surface free energy characteristics, fluorochemicals can handle paper fibers by surface sizing, sizing pulp paper and other craft making good anti-oil properties, can be used in food packaging, fast food packaging and other aspects of daily necessities, has good prospects. Recent study found that ammonium perfluorooctanoate fluorinated compounds produced during / perfluorooctane sulfonate(PFOA /S) exists harm to humans and the environment, low doses of PFOA/S can cause genetic, reproductive, developmental, liver and cardiovascular and other diseases, the EU, Environment Canada, the US Environmental Protection Agency has restricted the use of PFOA / S’s. Perfluoropolyether raw material for the preparation of fluorinated compounds do not generate PFOA/S, environmental pollution, harmful organisms, reducing the impact on the environment, environmental safety, people’s attention. This article was prepared by a novel perfluoropolyether Fluorinated anti-oil, anti-oil has a good performance, application prospects.In this paper, perfluoropolyether, N-N-dimethyl-propylene diamine, pHospHoric acid, sodium hydroxide, sodium chloroacetate, polyethylene glycol and the like synthesized perfluoropolyether type ampHoteric fluorine compounds:(1) perfluoropolyether, deionized water was synthesized fluorinated acid type perfluoropolyether oil repellent. By pulp sizing and surface sizing method, the influence of acid type fluorinated perfluoropolyether oil and oil-repellent properties of the paper. The results show that through the pulp sizing, anti-oil dosage is 1.8%, 5.0% water dosage, dosage 2.0% retention, retention aids retention time is 11 min, beating 30 degrees SR, the fluorine-containing oil-repellent having a good anti-oil properties; through surface sizing, a carboxylic acid type fluorinated perfluoropolyether oil repellent agent in an amount of 0.5%, the amount of polyvinyl alcohol 2.0%, the amount of cationic starch 2.0%, anti-oil grade nine.(2) perfluoropolyether, pHospHoric acid, sodium hydroxide, NN-dimethyl-propanediamine and polyethylene glycol pHospHate synthesized perfluoropolyether type oil-repellent fluorine studied perfluoro poly p HospHoric acid impact on paper and oil properties and oil repellent fluorinated ethers. The results show that through the pulp sizing, anti-oil dosage is 1.8%, 5.0% water dosage, dosage 2.0% retention, retention aids retention time is 11 min, beating 30 degrees. When SR, oil rating of 7; through surface sizing, a perfluoropolyether pHospHoric acid type fluorine-containing oil-repellent in an amount of 0.5%, the amount of polyvinyl alcohol 2.0%, the amount of cationic starch 2.0%, oil rating of 8 level.(3) perfluoropolyether, chloroacetic acid, sodium hydroxide, NN-dimethyl-propanediamine and polyethylene glycol, sodium chloroacetate synthesized perfluoropolyether type oil-repellent. The effects of acid sodium type fluorinated perfluoropolyether oil and oil-repellent properties of the paper pulp by the method and surface sizing. The results show that through the pulp sizing, anti-oil dosage is 1.8%, 5.0% water dosage, dosage 2.0% retention, retention aids retention time is 11 min, beating 30 degrees. When SR, oil rating of 7; when the sodium chloroacetate by surface sizing perfluoropolyether type oil-repellent fluorine-containing an amount of 0.5%, the amount of polyvinyl alcohol 2.0%, the amount of cationic starch 2.0%, oil rating 8. |
