In fento in situ Polymerization coated high molecular material green pulp and paper technology.
Background technique
Through from 105 years Christian eras Cai Lunyong bark, the numb plant materials such as head and worn-out cloth, fishnet and the techniques such as frustrating, smashes, copies, dries
Invention papermaking starts, and have passed through Shanxi and makes with Northern and Southern Dynasties fiber crops and the papermaking of paper mulberry skin and paper polish, Tang, Song Shiyong rattan and Sang Pi etc.
When paper, the Northern Song Dynasty Anhui use solarization night holding work hemp fiber with when paper processed, the Southern Song Dynasty produce bamboo paper and with the papermaking of paddy and wheat grass, member Ming and Qing
Hand papermaking, thousands of years of papermaking culture of the Chinese nation are continued to develop and are propagated, and have been continued slurrying substantially, have been modulated, manufacture paper with pulp, adding
The technique of work etc., environmental problems such as very important real estate unboiled water pollution, atmosphere pollution；The dependence of the resources such as timber is high, and
And resource recovery is low.
China is that an area of woods is relatively small, the timber resources also opposite country lacked, but the bamboo timber resource in China
But very abundant, so bamboo grove is referred to as " the second forest " in China.But at this stage using paper made of bamboo fibre because using
Bleaching agent will cause serious environmental pollution, and the application of paper will be limited if not using.The natural plant fibre base of synthesis is multiple
Condensation material can solve the problem of bamboo fibre bleaching agent environmental pollution just, combine the excellent of natural plant fibre and synthetic resin
Point, but due to the factors such as the thermal degradation of poor compatibility between fiber and resin and plant fiber process cause it is compound
The decline of material property constrains popularization and application of this material on paper technology.
Summary of the invention
For the deficiency of existing bamboo wood slurrying, propose a kind of to make full use of the environmentally protective and easily prepared of bamboo timber resource
Pulp and paper technology.
The technical scheme is that the method preparation using PVC woven fabric in-situ polymerization blending combination vacuum dehydration contains
There is the PVC resin powder master batch of bamboo fibre and then be used for papermaking, concrete scheme is as follows:
A kind of fento in situ Polymerization coated high molecular material green pulp and paper making method, slurry are prepared in reaction kettle,
Water and suspending agent are added into the feed inlet of polymeric kettle, closed polymeric kettle after modified initiator, air in the de- drop kettle of vacuum is added
With the oxygen being dissolved in material, then from air inlet be added monomeric vinyl chloride after start to warm up, stir, react and control temperature and
Pressure.Extract unreacted monomer after polymerization out, slurry is stripped, and vinyl chloride monomer, the slurry after gas bleeding are recycled
It is discharged and is centrifuged from discharge port, up to resin-in-pulp powder after sieving.Then magma feeding extruder is passed through into mouth mold
It is extruded into continuous slab, and rolls to form paper tire with calender, through big cylinder dried, adjusts the thickness uniformity by calender, most
It is wound afterwards by reel machine.Magma includes resin-in-pulp powder, auxiliary agent and modifying agent.Auxiliary agent in magma is to improve processing
Property, modifying agent is for adjusting polrvinyl chloride product surface hydrophilic or lipophilicity.Entire pulping and paper-making production process does not have to water and has
Malicious industrial chemicals has a preferable uniformity and mechanical strength at paper, at low cost, process strong adaptability, saving and alternative big
Timber is measured, while yield is big, high-efficient.
A kind of fento in situ Polymerization coated high molecular material green pulp and paper making method of the present invention, modified initiator packet
The particle of initiator containing PVC and fiber molecule chain, in conjunction with PVC initiator is carried out physical blending or chemical method with bamboo fibre
Together, realize that fiber molecule chain periphery coats initiator molecule, to prepare modified initiator.The resin-in-pulp powder prepared
Basic unit includes fiber molecule chain and PVC strand, and PVC strand replaces initiator particle to wrap fiber molecule chain
It covers, resin-in-pulp powder contains bamboo fibre, and fiber problem compatible with PVC resin powder is realized from source, is conducive to PVC cladding bamboo pulp
Preparation and uniformity.
A kind of fento in situ Polymerization coated high molecular material green pulp and paper making method of the present invention, the advantage is that:
(1) pulp and paper technology is environmentally protective, easy to implement；(2) it realizes resource cascade utilization, makes full use of bamboo timber resource and production capacity
Superfluous PVC resource；(3) it is easy to form to prepare paper for the PVC master batch containing bamboo fibre, can mass production, and greatly improve
Production efficiency；(4) paper surface prepared by can hydrophobic, oleophobic or hydrophilic, oleophylic, surface nature it is controllable.
