Abstract
The invention discloses sack paper, and relates to the field of packaging materials. The sack paper comprises a paper pulp layer and a glue binding layer which are compounded together through adhesives, the paper pulp layer is formed by mixing sulfate wood pulp with long fibers, and the glue binding layer is formed by compounding styrene-acrylic emulsion with rosin. The sack paper is tough in paper quality, not easy to fracture, fine in waterproof property and breathability, high in elongation and suitable for packaging industrial products such as cement, chemical fertilizers and pesticides.
Description
Technical field
The present invention relates to the packaging material fields, be specifically related to a kind of sack kraft paper.
Background technology
Sack kraft paper (stretchable paper) is similar to brown paper, produce mainly with the needlebush sulfate pulp greatly, domestic also have mix that part bamboo pulp, cotton stalk pulp, rag stock produces, so the sack kraft paper mechanical strength is very high, generally is used for making the packaging bag of cement, agricultural chemicals, chemical fertilizer and other industrial goods.requirement during for suitable can, sack kraft paper requires to have certain gas permeability and larger percentage elongation, application number is that CN201010594658.1 discloses a kind of stretched paper bag and production method thereof, operating weight part is 70～100 masson pine sulfate true qualities paper pulp, weight portion is 0～30 Eucalyptus sulfate true qualities paper pulp, paper pulp is through with slurry, 23%～28% beating consistency making beating, beating degree is 15～24SR, after making beating again through desanding, condiment, the pressurized screen fine screen, upper net forming, squeezing, front drying, the compression of stretching property, rear drying, batch, rewinding, pack and make, vertical tensile index of paper is 54～62Nm/g, the longitudinal tensile strain rate is 6.0%～8.1%, vertically tensile energy absorption index is 2.2～3.3J/g, the longitudinal tear index is 15～22mNm2/g, burst index is 4.3～5.3kPam2/g, air permeability is 3.5～15 μ m/Pas, but this sack kraft paper papery toughness is not high, easily break, water resistance is poor, gas permeability is bad, percentage elongation is low.
Summary of the invention
The technical problem to be solved in the present invention is to provide the sack kraft paper that a kind of papery is tough, percentage elongation is high.
For solving the problems of the technologies described above, a kind of sack kraft paper of the present invention comprises pulp layer and mucilage binding layer, and described pulp layer and mucilage binding layer are combined with each other by adhesive, described pulp layer is mixed by sulfate wood pulp and long fiber, and described mucilage binding layer is by benzene-acrylic emulsion and rosin is compound makes.
Preferably, described pulp layer thickness is 80 ~ 100 μ m.
Preferably, described adhesive is neoprene.
Preferably, described sulfate wood pulp and long stapled mass ratio are 3.5 ~ 4:1.
Preferably, the mass ratio of described benzene-acrylic emulsion and rosin is 1 ~ 2:1.
The invention has the advantages that: long fiber has the characteristics such as well-pressed, smooth, quick-drying washable, non-ironing and with low cost, the resistance to water alkali resistance is high, and other side will be lower than vinegar the third, thus the emulsion consumption high in high paint vinegar third to get well, the benzene emulsion that consumption is low is handy, uncle's acrylate and vinyl acetate emulsion is better, and therefore papery of the present invention is tough, is difficult for breaking, water resistance is good, good permeability, percentage elongation is high, is suitable for the packing of the industrial goods such as cement, chemical fertilizer, agricultural chemicals.
Description of drawings
Fig. 1 is the structural representation of a kind of sack kraft paper of the present invention.
Wherein: 1-pulp layer, 2-mucilage binding layer, 3-adhesive.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As shown in Figure 1, a kind of sack kraft paper comprises pulp layer 1 and mucilage binding layer 2, and described pulp layer 1 is combined with each other by adhesive 3 with mucilage binding layer 2, described pulp layer 1 is mixed by sulfate wood pulp and long fiber, described mucilage binding layer 2 is by benzene-acrylic emulsion and rosin is compound makes, and papery is tough, is difficult for breaking, water resistance is good, good permeability, percentage elongation is high, is suitable for the packing of the industrial goods such as cement, chemical fertilizer, agricultural chemicals.
It should be noted that described pulp layer 1 thickness is 80 ~ 100 μ m, described adhesive 3 is neoprene, and the thickness of 80 ~ 100 μ m has guaranteed tough, the elongation performance of sack kraft paper, and the neoprene bond properties is good, is suitable for using in the present invention.
In one embodiment of the invention, described sulfate wood pulp and long stapled mass ratio are 3.5 ~ 4:1, the mass ratio of described benzene-acrylic emulsion and rosin is 1 ~ 2:1, and the rational quality proportioning of pulp layer and mucilage binding layer can guarantee that tough, extensibility increases gas permeability in good.
Based on above-mentioned, the characteristics such as it is well-pressed, smooth, quick-drying washable, non-ironing and with low cost that long fiber has, the resistance to water alkali resistance is high, other side will be lower than vinegar third, so the emulsion consumption high in high paint vinegar third to get well, the benzene emulsion that consumption is low is handy, uncle's acrylate and vinyl acetate emulsion is better, therefore papery of the present invention is tough, be difficult for breaking, water resistance is good, good permeability, percentage elongation is high, is suitable for the packing of the industrial goods such as cement, chemical fertilizer, agricultural chemicals.
As known by the technical knowledge, the present invention can realize by other the embodiment that does not break away from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All within the scope of the present invention or the change within being equal to scope of the present invention all be included in the invention.
