Description
Technical field
The present invention relates to packing technique field, more particularly, to a kind of dampproof protection against insects file that delivery is packed for mail
Envelope.
Background technology
Envelope is sent to addressee by post office or express company after encapsulation letter or file, realizes sender and addressee
Information exchange between people；It is this to greatly save sender by way of envelope posts letter or file realizes information exchange
The road cost or time cost exchanged with the addressee human world, envelope mailing letter or file facilitate the life of people.At present, postal
The envelope that office or express company select is made for paper material, general paper material dampproof protection against insects poor performance.
The present inventor's early stage improves file and seals the hardness and deflection of itself once by using multi-layer mini-type corrugated board,
Ensure that file envelope possesses moistureproof and waterproof performance by being coated with waterproof layer, by using tack it is good, hold sticky strong and peel off strong
The high double faced adhesive tape of degree is sealed, and is split using tear strip, while encapsulating firmness is improved, facilitates fractionation behaviour
Make, and realize to file seal secondary recovery use, by addition have tearing to pieces property, the expendable antitheft edge of a knife, it is ensured that
File seals the delivery security of loaded article.
But it, which is still suffered from, needs improvements, such as during sea transport, the sea-freight time is longer, and marine ring
Border is in extreme humidity, and because file envelope humidity resistance is poor, file is sealed can not play protection to the article of transport therein
Effect.Existing file envelope is mainly papery shaping, is placed at the free time after the long period, and file envelope is often gnawed by insect bites, inner
Face sealed documents also goes to pot.
Currently on the market, the unitary function of file envelope, does not possess dampproof protection against insects performance completely, can not be compared with wet environment
Good protection file therein, and insect can not be avoided to gnaw bite, cause the loss for being difficult to retrieve.

Step 2) core paper and inner paper laminating, core paper is preheated to 40-50 DEG C, inner paper is preheated to and core paper identical temperature
Degree, by core paper and inner paper to molded, forms one.
Step 3) facial tissue pretreatment, will facial tissue carry out press polish processing after carry out offset printing, printed using oil-based ink,
254nm uv light irradiations 30-60min.
Step 4) dampproof protection against insects coating preparation, by coarse whiting, zinc oxide, nano titanium oxide, inorganic compounds of boron dispensing
Mixing, zinc oxide, nano titanium oxide, the addition of inorganic compounds of boron are the 10-60wt% of coarse whiting respectively, in ball grinder
Appropriate ethylene glycol, water are added, then ball milling 4h adds appropriate ammonium salt dispersant and wetting agent ball milling 1h, ammonium salt dispersant
It is preferred that E80 (high Supreme Being's Si production), the preferred X405 of wetting agent (Tao Shi productions), after discharging, with polyurethane thickener regulation system extremely
Appropriate viscosity is to obtain dampproof protection against insects coating.
Step 5) file envelope making, using K- formulas rubbing method, spraying process or knife coating to step 3) pretreatment face
Paper coats dampproof protection against insects coating, and paint thickness is 100-8000 μm, and upper Paper-pasting machine mounts facial tissue on core paper, so just makes
Go out on couch board, die-cutting machine cross cutting, patch brace machine patch haversack, forming machine and convert into, paste double faced adhesive tape and tearing adhesive tape.
Preferably, step 1) inorganic filler be kaolin, clay, titanium dioxide, gypsum, talcum, and naturally with synthesis
Both calcium carbonate, such as chalk, the marble crushed, the calcium carbonate and winnofil crushed；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, example
Such as it is based on rosin, dicthenone, ketene multimers, alkenyl succinic anhydrides；More preferably add dicthenone.
Preferably, step 2) preheating temperature be 45 DEG C.
Preferably, step 3) uv light irradiation 40-50min, more preferably 45min.
