Description
Technical field
The present invention relates to paper-based composite material prepared by a kind of waste and old paper and preparation method thereof, belong to composite neck
Territory.
Background technology
In recent years, China's paper consumption presents acceleration ascendant trend.China's paper products whole year total quantity consumed nearly hundred million in 2011
Ton, year total quantity consumed increases by 170% (period average growth rate per annum is more than 10%) compared with calendar year 2001, and the same period, the response rate only increased
It is 16%.It is true that rich in natural polymer subconstiuents such as a large amount of celluloses in waste and old paper, there is regeneration and prepare material and circulation
The value utilized.Therefore, based on above-mentioned condition, develop the Efficient Cycle of waste and old paper and utilize that to have environment double with economical
Weight benefit.Strengthening and the effort of the whole society's environmentally friendly economy of promotion, the height of waste and old paper along with Public environmental attitude
Quality secondary utilizes becomes focus of attention, and existing waste paper recycles mode, there is many drawbacks.
Recycle waste and old paper method outside induction and conclusion Present Domestic and approach mainly has three kinds: (1) waterpower recycled pulp
Technology: will separate by the paper pulp in paper base material, produce recycled writing paper.As Shandong century Sunshine Group company limited utilizes again
Raw waste paper is successfully prepared out packaging paper and Board (patent No.: 201020120918.7), additionally, Lu Zhangwen etc. have carried out waste paper
Research (patent No.: 97108542.0) this type of technology production cost of the high-grade paper for cleaning of preparation is low, but deposits in the course of processing
In potential secondary pollution.(2) wood technology is moulded: the paper base material wood fibre containing high-quality itself, this kind of technology is by them
Pulverize extruding to be combined with plastics, produce into and mould wood products.Yue Kong etc. utilize wastepaper-waste wood wood shavings to succeed in developing woodwork plate
(patent No.: 201310325784.0) water-tolerant.(3) color happy plate technique: by reclaim containing paper base material and other materials
Junk, after simple separation, is directly pulverized, hot-forming.As in Tetrapack, Co., Ltd utilizes waste and old paper substrate composite soft packaging
Garbage produces the technology of color happy plate, and Ding Qiuxia etc. utilizes waste paper to carry out the research of Thistle board class construction material,
All there is good value, but it not yet overcomes the factors such as energy consumption is high, processing conditions is harsh.(4) generative fuel technology: adopt
Close with Fiberight company of bio-fuel manufacturer with the generative fuels such as waste paper processing ethanol, such as Novozymes Company of Denmark
Make, use waste paper and waste paperboard to produce alcohol fuel, and be processed into E85 ethanol petrol and carried out automobilism experiment,
But this type of technology products obtained therefrom belongs to disposable products, it is impossible to again reclaim, it is unfavorable for realizing the long-term circulation of waste and old paper
Utilize.
Obviously, for domestic and international prior art situation, in addition to preparing regenerated paper pulp with waste paper, moulding material still with
Plastics are compound and mechanical press is as methods such as molding.But, these obtain the method for regrown material, and unfavorable shadow served by band
Ring: be difficult to degrade after (1) plasticizing: paper this for degradable biomass material, after abandoning can in natural decomposition under atmospheric environment or
Degraded, is difficult to cause environment chronic pollution, and the material after the result compound with plastics is so that abandonment loses big compression ring
Natural degradation or the advantage of decomposition under border；(2) new environmental contaminants are produced during recycling: such as waste and old paper deinking mistake
Cheng Zhonghui produces garbage in the middle of a large amount of, as a series of in sodium hypochlorite, fatty alcohol polyoxyethylene ether sulfate, Isosorbide-5-Nitrae-dioxanes etc.
Noxious substance, easily causes " secondary pollution " in cyclic process, causes vicious cycle；(3) the low-quality paper wood that remanufactures is at knot
Again become garbage after restrainting of short duration service life, do not solve relevant issues from fundamental way, it is impossible to give full play to papery
The natural characteristic of material.Due to the existence of these shortcomings above-mentioned, preparation reach corresponding mechanical property, regenerate pollution-free, improve and make
With the paper-based composite material in cycle etc., the economic and social benefit etc. improving the waste and old paper response rate, raising is reclaimed all is had
There is important meaning.
