2, thickness 2.3mm～2.5mm, tensile strength 〉=1.8kn/cm
2, immersion after 4 hours tensile strength 〉=0.8kn/cm2, interlaminar strength 〉=0.40kn/m, deflection be controlled at 235mn.m～315mn.m scope, has good performance when guaranteeing the cap cardboard as the brim of a hat, easily processing, processing back product is indeformable, the advantage that deflection is moderate.
The theoretical foundation of adding various auxiliary materials in the present invention is:
1, the interpolation of cationic starch
At first determine the use of cationic starch.Starch is converted starch extensive use papermaking enterprise particularly, it generally can be divided into following several types (1) cationic starch is under the existence with starch and cationic etherifying agent, anticoagulant, add thermal response and generate quaternary amine type, tertiary amine-type starch, strong suction-operated takes place owing to itself have the fibrous particle of cation energy and electronegative property in the solution.Therefore, it is added in the slurry, can be used as retention, filter aid and reinforcing agent; (2) anionic starch is that chemical reactions such as starch and phosphate, acetate generate, but presents negative electrical charge because of it in solution, and is poor with fiber knot and property, so additive effect is not good in the slurry, generally is coated with as surperficial; (3) nonionic starch, be starch and epoxy alkyl etherifying agent be blended in add anticoagulant under the alkali condition after, heating makes, and generally is not used in the slurry to add.At this principle, for considering manufacturing paper with pulp of heavu weights, improve water filtering performance, improve the l Water Paper mass dryness fraction, and strengthen the cardboard splitting, so select 3%～6% cationic starch for use.Therefore, one of this basic foundation that designs for the present invention.
2, the interpolation of carboxylic styrene butadiene latex and high-phenylethylene emulsion mixed impregnant liquor
Synthetic latex obtains develop rapidly in recent years, its reason can fully remedy the source deficiency of natural rubber, and some specific function of giving goods, as intensity, oil resistant, tear-resistant etc., its major product has styrene-butadiene latex, polychloroprene latex, NBR latex, carboxylated latex, butadiene latex, isoprene rubber latex, butyl latex, ethylene propylene rubber latex, acrylic latex, polyvinylchloride latex, polyvinyl acetate latex, polystyrene latex, high styrene latex etc., and wherein carboxylic styrene butadiene latex is most widely used general in paper conversion, it is on the basis of styrene-butadiene latex, add suitable unsaturated carboxylic acid, and the formation ternary polymerization, thereby carboxylic styrene butadiene latex stability and aspect of performance have been had significantly to be improved, its mechanism: the carboxyl that (1) is aggregated on the macromolecular chain is hydrophilic, and main chain is hydrophobic, and this structure can form interparticle " barrier " makes latex obtain to stablize.(2) because carboxyl combines with main chain with chemical bond, can not disconnect because of external shearing force or other factors.(3) even carboxyl generation ionization repels each other with latex particle because of it is electronegative and to separate, thereby improves its stability.Therefore, carboxylic styrene butadiene latex infilters in the paper in that the papermaking process is easier, while carboxylic styrene butadiene latex mechanical stability height, can bear the shear action of process, excellent machinability is arranged, simultaneously with the paper of this dipping, by extremely strong stretching, tear-resistant, folding and moderate hardness and water repelling property.But the carboxylic styrene butadiene latex overall hardness is on the low side, at this, the present invention considers that molecule increases with styrene-content in the styrene-butadiene latex, the characteristics that its glued membrane hardening, intensity improve, the present invention suitably selects the 10-20% high styrene latex for use, reaching reinforcement and to improve moderate soft durometer index, two of the basic foundation that this designs for the present invention.
3, the interpolation of wax emulsion and neutral sizing agent
Heavu weights is opened and will be satisfied extremely strong water repelling property, the most critical paper surface must have certain hydrophobicity material, could stop entering of hydrone and obtain certain water repelling property, the tradition water repellent agent has gum rosin, sizing agent (AKD), the wax emulsion, paraffin, organosilicon etc., therefore the present invention has selected the wax emulsion for use, this is efficient hydrocarbon mixture, refuse water, anti-water electrode is strong, but consider the infiltration of dipping portion latex, the present invention has only added 0.05%～0.08% on a small quantity, select cationoid reaction type glue used in paper-making (SR) in a large number for use, this is epoxychloropropane and triethylene tetramine copolymer, starches interior interpolation, helps to combine with fiber, improve sizing efficiency, this for the present invention designs basic foundation three.
With the technical scheme in the foregoing description is example, and made paper hat brim can reach following technical indicator:
| Index | Unit | Regulation |
| Thickness | ??Mm | ??2.4±0.20 |
| Tightness | ??g/cm 3 | ??0.56±0.20 |
| Tensile strength | ??kN/cm 2 | ??≥1.8 |
| Immersion 4H tensile strength | ??kN/cm 2 | ??≥0.8 |
| Splitting | ??kN/cm | ??≥0.40 |
| Deflection (mean value) | ??mN.m | ??235--315 |
| Immersion 1H percentage elongation | ??％ | ??≤1.8 |
| High temperature drying 1H shrinkage factor | ??％ | ??≤1.5 |
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
