Description
Technical field
The present invention relates to the fields such as macromolecular material packaging, papermaking, printing, specifically, relate to a kind of fire-resistant moisture resistance and high tenacity gel paper and preparation method thereof.
Background technology
The accumulation of Zhi Shi Han nationality working people protracted experience and crystallization of wisdom, for writing, printing, paint or the sheet-like fiber goods of packaging etc.At ancient times, ancestors mainly rely on and keep records by tying knots, and have gradually invented the inscriptions on bones or tortoise shells later, start with first bone as writing material.Found again and utilized bamboo chip and wood chip and fine silk silks as writing material afterwards.But because fine silk silks is too expensive, bamboo chip is too heavy, so just result in the generation of paper.According to textual criticism, during the Chinese Western Han Dynastry, start the making of paper, early Medieval China paper in period widespread, and be commonly people and use.Along with papermaking technology improves further, paper making raw material is also diversified, a multitude of names of paper, as bamboo curtain splint paper, rattan paper, fish-egg paper etc.The raw material of Cai Lun papermaking is extensive, and the paper made with rotten fishing net is on net paper, and the paper that rag is made is on cloth paper.Sui-Tang bines; Famous rice paper is born.The Tang Dynasty contaminates on the basis of yellow paper at former generation, evenly waxes again on paper, and make paper have gloss jade-like stone profit, the advantage of gorgeous U.S., it is called hard yellow paper.During to Shanxi generation (4th century), paper finally replaces silks letter becomes main writing material.
The kind of paper is a lot, and classification of habits method is as follows:
1, hand-made paper and machine-made paper is divided into by the mode of production.Hand-made paper, based on manual operations, utilizes curtain screen frame frame, manually the system of dragging for forms one by one.Quality is soft, and suction force is strong, is suitable for ink and writes, paint and print use, as the rice paper of China.The proportion of its output shared by the ultimate production of Modern Paper is very little.Machine-made paper refers to the general name of the paper of mechanized manner production, as printing paper, wrapping paper etc.
2, paper and paperboard is divided into by the thickness of paper and weight.Both still do not have strict distinguishing limit.General be called paper with every below weight per square meter 200g, above is called cardboard.Cardboard accounts for about 40 ~ 50% of paper ultimate production, is mainly used in commodity packaging, as Case Board, packaging board etc.Usual in the world paper and paperboard to be added up respectively.
3, being divided into by purposes: newsprinting paper, is a kind of main specialty printing paper for journalism, because proportion is comparatively large, and a single-row class traditionally; Printing paper, writing paper, for printing and writing and comprise drawing and drawing paper using; Wrapping paper; Kraft paper; Technical paper (industrial or agricultural technical paper); Living-hygienic paper using; Base paper, for manufacturing converted paper further; Cardboard; Converted paper etc.
By upper sight it, the manufactured materials of current paper is mostly processed from strand by vegetable fibre and non-plant fibre (inorganic fibre, man-made fiber, steel fiber etc.).The feature of paper has a lot, the most generally use now with vegetable fibre be main raw material synthesis paper has light weight, water-absorbent is strong, hardness is little, snappiness is poor, the feature of foldable, not easy conductive.But its under the outside atmosphere of complexity (temperature, humidity, electric field change are frequent) easily there is paper spontaneous combustion, the phenomenon such as mouldy, the corrosion of becoming damp, not easily life-time service and preservation.Modern science and technology is in order to meet paper application under given conditions, and adopting increases that some has additive of specific function or coating, the mode of synthesis carries out compound.Such as, the Aerogel paper that Chinese patent CN103334336A provides, is composited by aerosil and glass fiber paper.Thickness is 0.3 ~ 1.2mm.There is the same flexibility of sensitive paper and flexibility, can resistance to 600 DEG C of high temperature, nonflammable and thermal conductivity is low.Chinese patent CN103303930A prepares the minimum Aerogel paper being only 0.3mm of thickness, by being used alone or superposing use this Aerogel paper, almost can apply to all occasions needing heat-insulation and heat-preservation.
Along with macromolecular material---the development of plastics, rubber, fiber and tackiness agent and widespread use, plastic paper arises at the historic moment.Plastics to synthesize or natural macromolecule resin is main raw, after adding various auxiliary agent, has ductility under certain temperature and pressure, can fix a class material of its shape after cooling.Plastic paper is the one of converted paper, and outward appearance is as the goods of laminated plastics, tough and tensile and frivolous, has waterproof, the superior character such as acidproof and alkaline-resisting, can for the surrogate of shell etc. manufacturing toy, furniture, receiving set and televisor.In addition the cellulose paper humidity that uses than usual of polymer paper is high, fold resistant, not yielding, water-fast, the advantage of chemical-resistant resistance and the easy modification of micro-raw burn into, easily processing, but, the poor rigidity of polymer paper, and owing to not being decomposed by the microorganisms, difficult treatment, easy contaminate environment, thus limits production and the use of polymer paper.
For the snappiness solving vegetable fibre paper is poor, burning-point is low, the shortcoming of going mouldy of easily becoming damp, we have prepared a kind of macromolecule hydrogel paper material.Macromolecule hydrogel is the superpolymer that a class has three-dimensional net structure.The three-dimensional net structure of gel itself makes it have excellent fire performance, is suitable for preserving under high fire hazardous situations and using; The water conservation water storage performance of its uniqueness can humidity environment that effectively adaptation material itself is residing, has excellent humidity characteristic, and along with the change of outside atmosphere self-regulation to an equilibrium state; The MULTIPLE COMPOSITE crosslinking method of gel itself make it possess paper is necessary writes intensity, and provide high toughness, make paper not easily occur folding line, fold, effectively keep the complete of institute's recording materials.Necessary intensity when the present invention has taken into full account that paper uses, the raw materials cost adopted is low, technique simple, be easy to bulk industrial produces, and have and manufacture the features such as simple and cost is low, the gel paper obtained has excellent resistivity against fire, moisture resistivity and high tenacity, the place that external environment condition (temperature, humidity etc.) changes greatly can be widely used in use for a long time, also gather around under extreme weather area and engineering-environment and have wide practical use.
