Description
Technical field
The invention belongs to blank synthetic paper production technical field more particularly to a kind of knots of the blank synthetic paper of two-sided writing
Structure and its production technology.
Background technique
Since the forest reserves are gradually few, paper raw material demand becomes new problem for the world today (especially China).Synthetic paper
Production process can not only solve the problems, such as raw material based on polypropylene and Paris white, and more important is both raw materials are pollution-free
Property, generation waste material is also recyclable in the fabrication process, does not use such as and does not also pollute air.Synthetic paper has at low cost, strong
Spend the characteristics such as excellent, printing performance is good, water-fast, oil resistant, drug resistance, there is wide prospect in function and purposes, be suitable for the people,
The all trades and professions such as quotient, work, army.Current synthetic paper technique is mostly membrane process or fibre method, high to high molecular material performance requirement,
Material needs import or modification, and manufacturing cost is high.With synthesize high molecular material (such as polyethylene, polypropylene) with membrane (press mold or
Blown film) method page semi-finished product are made, be then allowed to paper using method chemically or physically, as sandization can increase it is impermeable
Lightness can obtain lyophobic performance etc. with chemicals processing surface.Synthetic pulp can be used in another kind of synthesis paper product, through beating
It manufactures paper with pulp after slurry processing.Synthetic paper has high tensile strength, high tearing strength, good insulation performance, optical property
With excellent wet strength.As insulating materials, chart paper, military map paper etc..Its primary raw material is polyethylene, polypropylene, gathers
The organic resins such as styrene.Preparation method is that above-mentioned resin is generated by melting, extruding, film forming along axially different stretching first
Film；Then, which is carried out " paper-like " processing, is allowed to become opaque, whiteness raising, synthesis has then just been made
Paper.The tensile strength of this paper is high, and it is not afraid of water, do not damage by worms, be flexible, can heat-insulated, dimensionally stable, smooth surface, be suitable for
Books and periodicals and printing.It is mostly used wide come fishery paper processed, nautical chart, perforating hole card, water-fast newpapers and periodicals, disc envelope, Commercial goods labels, open air
Announcement, business card etc..The disadvantage is that folding quality is poor, there is not evanescent folding line after folding, useless synthetic paper recycling is had any problem.
Blackboard plays great role in modern school instruction, is placed in support by being fixed on metope or installation,
It is write by chalk in blackboard surface and is then altered by blackboard eraser, biggish dust can be generated in this way, further, since blackboard eraser ratio
It is smaller, it rubs relatively elaborate, has in the prior art to blackboard panel material improvement, by selecting with magnetic white in this way
Plate, white board writing is clear, and modification is convenient, but since white board marker trace is thinner, is sitting in and is not readily visible apart from farther away student,
Quality of instruction is influenced, blackboard in the prior art is easy to produce larger dust, has a single function, and cannot send out for the teaching of diversification
Wave advantage.
Currently, blank material uses PET as substrate mostly, the primary solvent of white board marker pen oil is alcohol, it is desirable that material
Having an excellent resisting alcoholic energy, traditional blank material mostly uses the mode of overlay film after first printing to carry out, but as hereafter
Continuous production technology is complicated, and covered film is difficult white board marker writing after accomplishing light aging gently to wipe number by pine, it is often necessary to heavy
Solvent rub is newly used, user is caused and uses difficulty.The difficult point for developing this material is that coating material is necessarily required to treat
Alcohol possesses absolute resistance, additionally needs to take into account ink printing performance.
China Patent Publication No. is CN102584105A, and invention and created name is a kind of production technology of synthetic paper, special
Sign is, processing step are as follows: (1) prepares synthetic paper and prepare raw material；(2) resin and auxiliary agent are added in high-speed mixer and are filled
Divide mixing；(3) material mixed is sent to preplasticizing in mixer；(4) extruder is transported to after to be plasticated repeatedly plasticizing；
(5) it is sent into calendering formation in calender；(6) deflected from roller extraction, then through cotton ginning, cooling, thickness measuring, batch to obtain product.
But there is the blanks of production not to tolerate alcohol in white board marker pen oil for the blank synthetic paper of existing two-sided writing
Erosion, the surface that ink is attached to blank be difficult to wipe and can not anti-light aging the problem of.
