Description
Technical field
The present invention relates to packing technique field, especially relate to a kind of dampproof protection against insects file envelope delivered for mail packaging.
Background technology
Envelope, after encapsulation letter or file, is sent to addressee by post office or express company, it is achieved the information exchange between sender and addressee；This can be greatly saved, by the way of envelope mailing letter or file realize information exchange, road cost or the time cost that sender exchanges with the addressee human world, letter posted by envelope or file facilitates the life of people.At present, the envelope that post office or express company select is that paper material is made, general paper material dampproof protection against insects poor performance.
The present inventor's early stage is once by using multi-layer mini-type corrugated board, improve hardness and the deflection of file envelope self, ensure that file envelope possesses moistureproof and waterproof performance by coating waterproof layer, by using, tack is good, it is strong to hold viscosity and peel strength is high double faced adhesive tape seals, and utilize tear strip to split, while improving encapsulating firmness, facilitate fractured operation, and achieve the secondary recovery use to file envelope, by interpolation, there is tearing to pieces property, the expendable antitheft edge of a knife, it is ensured that the delivery safety of file envelope loaded article.
But it still suffers from needing improvements, during such as sea transport, the sea-freight time is longer, and the environment at sea is in extreme humidity, and owing to file envelope humidity resistance is poor, the article of transport therein cannot be played a protective role by file envelope.The envelope mainly papery molding of existing file, is placed at the free time after the long period, and file envelope is often gnawed by insect and bitten, and the inside sealed documents also goes to pot.
Currently on the market, the function singleness of file envelope, the most do not possess dampproof protection against insects performance, wet environment can not preferably protect file therein, and insect cannot be avoided to gnaw bite, cause the loss being difficult to retrieve.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of file envelope with preferable dampproof protection against insects performance and production technology thereof.
First, the present invention provides the file envelope production technology with preferable dampproof protection against insects performance, by spraying dampproof protection against insects coating between facial tissue, core paper, inner paper, forms micron order protective layer, prepares the file envelope of dampproof protection against insects function admirable.Specifically, including:
Step 1) core paper and the preparation of inner paper: in chemical wood pulp, add reed pulp or the straw pulp of 10-20wt%, add d cyphenothrin water emulsifier, addition is the 0.1-0.5wt% of chemical wood pulp, obtains suspension, prepares core paper after agitated shearing further.The inorganic filler of general type is added in chemical wood pulp, such as Kaolin, clay, titanium dioxide, Gypsum Fibrosum, Talcum, with natural and both synthetic calcium carbonates, the such as marble of Chalk, pulverizing, the calcium carbonate of pulverizing and winnofil, paper in preparing further after agitated shearing.
The paper stock of core paper and inner paper the most also can be containing other additive for paper making, and such as wet strength agent, sizing agent, such as based on Colophonium, dicthenone, ketene multimers, alkenyl succinic anhydrides etc..
Step 2) core paper and the laminating of inner paper, core paper is preheated to 40-50 DEG C, inner paper is preheated to the temperature identical with core paper, by core paper and inner paper to molded, form one.
Step 3) pretreatment of facial tissue, carry out offset printing after facial tissue is carried out press polish process, use oil-based ink to print, 254nm uv light irradiation 30-60min.
Step 4) preparation of dampproof protection against insects coating, by triple superphosphate, zinc oxide, nano titanium oxide, the mixing of inorganic compounds of boron dispensing, zinc oxide, nano titanium oxide, the addition of inorganic compounds of boron are the 10-60wt% of triple superphosphate respectively, appropriate ethylene glycol, water is added in ball grinder, ball milling 4h, it is subsequently adding appropriate ammonium salt dispersant and wetting agent ball milling 1h, the preferred E80 of ammonium salt dispersant (high Supreme Being Si production), the preferred X405 of wetting agent (Tao Shi production), after discharging, i.e. obtain dampproof protection against insects coating by polyurethane thickener regulation system to appropriate viscosity.
Step 5) file envelope making, use K-formula rubbing method, spraying process or knife coating to step 3) the facial tissue coating dampproof protection against insects coating of pretreatment, paint thickness is 100-8000 μm, facial tissue is mounted on core paper by upper Paper-pasting machine, the most just couch board is produced, die-cutting machine cross cutting, patch braces machine patch haversack, equivalent on forming machine, patch double faced adhesive tape and tearing adhesive tape.
Preferably, step 1) inorganic filler be Kaolin, clay, titanium dioxide, Gypsum Fibrosum, Talcum, and natural with both synthetic calcium carbonates, the such as marble of Chalk, pulverizing, the calcium carbonate of pulverizing and winnofil；More preferably winnofil.
Preferably, step 1) core paper and inner paper in add other additive for paper making, such as wet strength agent, sizing agent, such as based on Colophonium, dicthenone, ketene multimers, alkenyl succinic anhydrides etc.；More preferably add dicthenone.
Preferably, step 2) preheating temperature be 45 DEG C.
Preferably, step 3) uv light irradiation 40-50min, more preferably 45min.
Preferably, step 4) zinc oxide, nano titanium oxide, the addition of inorganic compounds of boron be the 20-40wt%, more preferably 30wt% of triple superphosphate the most respectively.
Preferably, inorganic compounds of boron is boron oxide, boron nitride, more preferably boron oxide.
Preferably, step 5) paint thickness be 100-8000 μm, preferably 1000-3000 μm, more preferably 2000 μm.
The present invention, by adding d cyphenothrin water emulsifier in the raw material wood pulp of core paper and inner paper, makes wood pulp itself have insect protected performance, enhances the insect protected performance of file envelope.Meanwhile, by uv light irradiation after facial tissue press polish, offset printing, coat dampproof protection against insects coating, further ensure the dampproof protection against insects performance of file envelope.Although the present inventor can not its reason of theoretical explanation, but the inventors discovered that the irradiation of uviol lamp is the most necessary for the coating of dampproof protection against insects coating, even if using identical dampproof protection against insects coating, after uv light irradiation, the dampproof protection against insects performance of gained file envelope is better than directly coating the file envelope of dampproof protection against insects coating without uv light irradiation.
The file envelope entirety of brand new the most provided by the present invention changes the security performance of traditional file envelope, has stronger marketing use value.
