Description

A kind of fire-retardant brown paper
Technical field
The present invention relates to field of papermaking, specifically disclose a kind of fire-retardant brown paper.
Background technology
Packaging material is to one of the major function that the protectiveness of built-in amount of substance is packaging, and inner packing is even more to be protected to commodity Shield property plays the role of vital.
Brown paper is tough and tensile water-fast package paper, is in brown color, has many uses, main quality requirement is flexible knot Real, bursting strength is high, can bear larger pulling force and pressure does not rupture, and is mainly used for wrapping paper, envelope, paper bag etc. and printing machine rolling Cylinder cylinder-packing etc..
However, although brown paper has a higher tearing toughness, but the common fault that unavoidable paper is inflammable, for The storage of brown paper brings limitation with use, therefore the anti-flammability for improving brown paper has application value very much.
Invention content
In order to overcome shortcoming and defect existing in the prior art, the purpose of the present invention is to provide a kind of fire-retardant ox-hides Paper.
To achieve the above object, the present invention uses following scheme.
There is a kind of fire-retardant brown paper lamination layer structure, composite layer to be followed successively by flame-retardant layer, kraft paper core, and filled layer is fire-retardant Layer, filled with fire extinguishing material in the filled layer.The group of fire extinguishing material becomes tetrachloro Bromofume, ammonium carbonate and talcum powder, matter Amount is than being 1:12:10.
Wherein, the fire extinguishing material in filled layer by accidental destruction and when burning, can play resistance in brown paper because of flame-retardant layer The effect of combustion and fire extinguishing, prevents the burning of brown paper.
Wherein, flame-retardant layer is formed by top sizing.Flame-retardant layer is by 30-45 parts by weight epoxy-polyurethane adhesive, 5-10 weight Part melamine, 10-12 parts by weight of urea, 3-5 parts by weight of phosphoric acid front threes phenyl ester, 1-3 parts by weight magnesium hydroxide, 2-6 parts by weight Line borate, 3-10 weight parts of calcium carbonate, 15-22 parts by weight hydroxypropyls PASELLI EASYGEL, 6-11 parts by weight sodium perborate composition.
Fire-retardant brown paper can be formed by flame-retardant layer, kraft paper core, filled layer and flame-retardant layer are compound successively, specifically, will Wood pulp, starch and sugarcane fasciated fiber are by weight 10:4:2:1 is mixed, and passes through size degradation, purification, flotation and defibrination process Gained slurry is manufactured paper with pulp afterwards, obtains kraft paper core；By two kraft paper cores and fire extinguishing material therein is placed by pressing, is formed Filled layer；After kraft paper core and filled layer pressing, flame-retardant layer is formed in top sizing, to obtain fire-retardant brown paper.
Surface sizing method is：
(1) melamine, urea, tricresyl phosphate are mixed first, is added in reaction kettle, alcohol solvent is added, then Magnesium hydroxide and line borate, calcium carbonate are added, is heated to 160-180 DEG C, soaking time 1-1.5 hours；
(2) hydroxypropyl PASELLI EASYGEL, sodium perborate, 65-85 DEG C of temperature, reaction time 2-3 hour is secondly added；Then plus Enter the stirring of epoxy-polyurethane glue, forms glue；
(3) it is stirred evenly after water repellent agent being added in glue, mixed glue solution is then transported to holding vessel, then will be in holding vessel Glue is delivered directly in sizing applicator, is carried out top sizing, is then dried, and top sizing layer is formed.
Beneficial effects of the present invention：Fire-retardant brown paper has been obviously improved Flame Retardancy, prevents it as packaging material When lose because of combustion zone.
Description of the drawings
Fig. 1 is the structural schematic diagram of size applicator of the present invention.
Specific implementation mode
For the ease of the understanding of those skilled in the art, the present invention is made further with reference to embodiment and attached drawing Bright, the content that embodiment refers to not is limitation of the invention.
The preparation method of fire-retardant brown paper is：It is formed by flame-retardant layer, kraft paper core, filled layer and flame-retardant layer are compound successively, Specifically, the kraft paper core, by wood pulp, starch and sugarcane fasciated fiber and by weight 10:4:2:1 is mixed；Pass through Gained slurry is manufactured paper with pulp after size degradation, purification, flotation and defibrination process, obtains kraft paper core；By two kraft paper cores and placement Fire extinguishing material therein passes through high pressure, forms filled layer；After kraft paper core and filled layer pressing, in top sizing, ox is formed Mulberry paper.
Surface sizing method is：
Embodiment one：
(1) 5 parts of melamines, 10 parts of urea, 5 parts of tricresyl phosphates are mixed by weight first, are added in reaction kettle, Then the 1 part of magnesium hydroxide, 6 parts of line borates, 10 parts of calcium carbonate for adding proportional quantity, are heated to 180 DEG C, soaking time 1.5 is small When；
(2) said mixture is added in hydro-thermal tank, and sequentially adds 15 parts by weight hydroxypropyl PASELLI EASYGELs, 11 weight Part sodium perborate, 85 DEG C of temperature, 2 hours reaction time；Then the stirring of 45 parts by weight epoxy-polyurethane adhesive is added, forms glue
