Description

The colored external packing smoke box of a kind of LWC environmental protection ink cardboard

Technical field

The present invention relates to the cigarette raw and auxiliary material, the colored external packing smoke box of promptly a kind of LWC environmental protection ink cardboard.

Background technology

The cigarette outer packing box is the special-purpose corrugated case that is used for cigarette package, for a long time, domestic main employing be the common corrugated case that yellow plate sheet lining simply prints.In recent years, because the fineness of external packing instructions, the part cigarette enterprise has adopted the external packing corrugation smoke box of offset printing colored printing, it is with fluting medium, boxboard, be combined into four layer paperboards by corrugated paper board production line, after precuting, paste the facial tissue that offset printer is brushed with pattern and character, after on four layer paperboards, carry out cross cutting with the applying glue by facing machine, the offset printing encaustic tile corrugated paper board cigarette case of moulding, its exterior design literal is clear, bright in colour, attractive in appearance, so be subjected to the favor of most of cigarette enterprises, but also have following defective: one contains solvent borne oil-based ink composition and applying glue because of offset printing external packing smoke box, its discarded object has harm to human body, causes for the second time to environment and pollutes; It two is to be the solvent-borne type product because of offset ink and applying glue, itself contains organic compound, volatile organic content pollutes to environment in process of production, solvent in product not volatilization organic residual give the consumer healthyly bring harm, and as the exporting packing case, be prohibited from entering western developed country, simultaneously, its complex manufacturing, the production cost height.

Summary of the invention

In order to solve the health problem of the existing secondary pollution of the colored smoke box of external packing, solvent type ink and the harmful human body of applying glue, the present invention proposes and a kind ofly not use solvent ink, the glue of need not fitting, and the colored cigarette extranal packing box cardboard of nontoxic environmental protection LWC ink.

The colored external packing smoke box of this LWC environmental protection ink cardboard, be with facial tissue, fluting medium, ordinary case paperboard is after being processed into cardboard through corrugated paper board production line, on cardboard, adopt water color ink printed patterns literal, it is characterized in that: facial tissue is a LWC, smoothness is 500～1000s, the unit are facial tissue weighs 200～220g/ ㎡, the cardboard wet weight is 7～10%, thickness 4～6 ㎜, the water color ink consumption is counted 4.5～6g/ ㎡ with solid content, the operation of printing water color ink is followed successively by: paper feeding, printing, last water-based gloss oil, oven dry, the collection plate, cross cutting is put cardboard, cross cutting collection plate, folding and unfolding cardboard speed be 100-150 open/minute, rate of drying 0.05-0.12 second/open.

The preparation method of water color ink is as follows:

One, get material ready by following part by weight:

A, emulsion acrylic resin, 15 parts～35 parts,

B, solid pigment, 20 parts～40 parts,

C, water, 25 parts～35 parts,

D, ethanol, 2 parts～8 parts,

E, ethanol ammonium, liquid, 1 part～6 parts,

F, defoamer, i.e. organic silicone, liquid, 0.1 part～0.3 part;

Two, make mill base, in milling apparatus, add institute and be equipped with 1/2 of emulsion acrylic resin, add in the stirring solid pigment be equipped with 2/3 of water, stir and grind after 20-40 minute, solid particle size is controlled at 5～10um, and is standby after qualified;

Three, preparation printing ink, in agitator, slowly add in turn ground mill base and be equipped with 1/2 of emulsion acrylic resin, stir, and 1/3 mixing ethanol and being equipped with water, add organic silicone and ethanol ammonium again, stir and promptly get the printing ink first product after 20-40 minute;

Four, quality inspection:

A, usefulness fineness instrument detect the particle diameter of solid, are controlled at 5～10um;

B, carry out the form and aspect adjustment with the color matching instrument, the printing ink first product that adds different colours by required form and aspect is mixed colours;

C, usefulness 100-140 order screen pack filter, pack, and get the printing ink finished product and are equipped with printed paperboard usefulness.

Product of the present invention has following advantage:

1, water color ink free from extraneous odour, avirulence are fit to the various LWCs of flexographic printing, and workshop condition is not contaminated in the production, no hazard residue thing on the paper;

2, can not produce secondary environmental pollution, carton with after, recyclablely be used to copy paper, economize on resources;

3, can increase carton side pressure strength, expose intensity and compression strength, can be widely used in the packing of product of industries such as food, health and exporting packing.

4, owing to reduced veneer, pressing plate operation, improved production efficiency, reduced production cost, strength of paper is improved.
