Description

Paper that a kind of difficulty is torn and preparation method thereof
Technical field
The present invention relates to a kind of paper and preparation method thereof, be specifically related to paper that a kind of difficulty tears and preparation method thereof, belong to paper preparing technical field.
Background technology
Along with the continuous enhancing of people's environmental protection consciousness, the exploitation of degradation material has become the study hotspot of Material Field 21st century.Be no matter the refuse pollution problem for solving packaging material, or in order to solve the raw material resources problem of the increasingly exhausted plastics industry of material feedstock especially based on petroleum resources, research and development degradation material is all significant.
As human being's production and the requisite fibrous material of life, its discarded object also receives much concern, especially the chemical fibre of Prof. Du Yucang, is difficult to degraded, has become new pollution sources.Method of reproduction, combustion method and edman degradation Edman is mainly adopted to process these discarded objects at present, wherein generally acknowledge that the best approach is edman degradation Edman, and in this several method of biodegradation, light degradation and thermal degradation, biological degradation method is low, effective and noticeable with its original again.BIODEGRADABLE FIBER MATERIAL refers to the fibrous material that degraded can be occurred under enzyme or chemical breakdown effect by microorganism (as bacterium, fungi, algae etc.) or its secretion under certain hour and suitable natural conditions.BIODEGRADABLE FIBER MATERIAL is environment amenable material, and it can help the mankind to reduce burden to environment, keeps modern civilization and natural relative equilibrium, therefore by one of majority fibers becoming 21 century.
The synthetic method of Biodegradable material mainly contains biological synthesis process, chemical synthesis macromolecule method, natural macromolecule modification method etc., and wherein biological synthesis process adopts microorganism or adopts gene chemical synthesis, is the synthetic method most with vitality and bright prospects.
The BIODEGRADABLE FIBER MATERIAL being applied to medical domain is generally all harmless to human non-toxic, the macromolecular material that can be absorbed after inside of human body disintegrate or excrete.Medical degradable fiber is divided into natural degradable fiber and Prof. Du Yucang degradation of fibers two class.Natural degradable fibrous material is all taken from organism material or natural materials, completes degraded in vivo by enzyme catalysis, as collagenous fibres, calcium alginate fibre, poly (hydroxyalkanoate) fibrid and chitin kind fiber etc.Prof. Du Yucang degradation of fibers has poly-dioxanone fiber (PDS), vinal (PVA), polyglycollide fibre (PGA) and poly-third glycolide fiber (PGLA) etc.The most important purposes of biodegradable medical fibre is exactly operation suture thread, and that relatively commonly uses at present has: poly-to dioxanone fiber (PDS), acid fiber by polylactic (PLA), poly (hydroxyalkanoate) fiber (PHA) etc.In addition, slower fiber such as the polycaprolactone fiber etc. of some degradeds can be made into the biodegradable fiber with insoluble drug release function; Alginate fibre also can be used as the carrier of medicine, for controlling the release of medicine.
Chinese Patent Application No. CN201210548235.5 discloses a kind of paper, and its at least one surface is applied with the microcapsules of parcel antibacterial material, and the antibacterial material wrapped up in these microcapsules is have the volatile essential oil of antibacterial functions, natural extract or natural organic matter.Paper surface of the present invention is applied with the microcapsules of parcel antibacterial material, the diffusion that effectively prevent antibacterial material before using is run off, in use procedure, paper acts on microcapsules pressure-rupturable through wiping, rubbing, fold etc., and the antibacterial material inside microcapsules discharges and plays effective antibacterial effect.But the characteristic of this paper is antibacterial, do not have environment-friendly degradable function, so it is significant to develop a kind of biodegradable paper and preparation method thereof.
