Referring to fig. 1, a high-strength flame-retardant kraft liner board for packaging comprises a paper core layer board 1, flame-retardant layer boards 2 and buffer layer boards 3, wherein the flame-retardant layer boards 2 are bonded to two sides of the paper core layer board 1, and the corresponding buffer layer boards 3 are bonded to the outer sides of the flame-retardant layer boards 2. Compared with the existing kraft paper board, the high-strength flame-retardant kraft paper board has higher strength toughness and flame-retardant effect, and the high-strength flame-retardant kraft paper board can be suitable for more environments through the arranged paper core board 1 with high toughness and the flame-retardant layer board 2 with fireproof capability, and the buffer layer board 3 can improve the capability of preventing fine cracking on the outer side of the kraft paper board.
Example two
Referring to fig. 1, based on the above embodiment, a method for preparing a high-strength flame-retardant kraft liner board for packaging is used for the high-strength flame-retardant kraft liner board described in embodiment one, and the method includes:
s1: obtaining waste clothes and waste corrugated boards; selecting cotton clothes, crushing the cotton clothes to obtain clothes fragments with the area smaller than 300 square millimeters, crushing waste corrugated paper boards to obtain paper board fragments with the area smaller than 300 square millimeters, and determining the size of the crushed waste clothes and the crushed waste corrugated paper boards according to the self-manufacturing requirement by a user during specific operation, wherein the fragments with the larger length-diameter ratio are easier to break out fibers, and the embodiment is not limited.
S2: putting the waste clothes and the waste corrugated boards into a pulping system according to the part ratio of 1:4; when corrugated container board is as the main raw materials of production cowhide cardboard, can provide enough short fiber and long fiber, the clothes can provide more long fiber, and long fiber and short fiber's combination can prepare the different plywood of function, and a plurality of laminates that have different functions match each other, can improve the whole usability of cowhide cardboard.
S3, performing S3; the pulping system breaks, bleaches, screens and concentrates the waste clothes and the waste corrugated board to prepare primary slurry; the clothing chips and corrugated board chips are mixed with alkaline solution and white liquor in a digester of a pulp mill and cooked at high temperature to dissolve lignin and separate into cellulose fibers, and then the fibers are washed, screened and bleached to obtain primary pulp containing fibers with uniform color.
S4: adding persulfate initiator and melamine polyphosphate into the primary slurry, and stirring to obtain secondary slurry; the ratio of the parts of the primary slurry to the persulfate initiator to the melamine polyphosphate is 10:0.5:1. The persulfate initiator and the melamine polyphosphate are mixed with the fiber, so that the flame retardant can be prepared in the fiber solution, and the flame retardant has high nitrogen content, low price, high flame retardant efficiency, excellent electrical performance and mechanical performance, no color change, low smoke and low corrosiveness. Meanwhile, the flame retardant is low in toxicity, safe to a user, good in environmental compatibility and good in thermal stability, so that the flame retardant directly attached to the surface layer of the fiber enables the fiber to have a certain flame retardant effect.
S5: stirring the secondary slurry, and screening to obtain flame-retardant long fibers and flame-retardant short fibers; the length of the flame-retardant long fiber is more than 50mm, and the length of the flame-retardant short fiber is 20-50mm.
S6: taking out the flame-retardant long fibers, mixing the flame-retardant long fibers and the papermaking auxiliary agent according to the part ratio of 5:1, and carrying out papermaking, squeezing, drying, surface sizing and drying to obtain the paper core laminate 1; the thickness of the paper core plate 1 is 3mm. Because the flame-retardant long fibers have the flame-retardant function, the flame-retardant effect of the paper core laminate 1 prepared by polymerizing the flame-retardant long fibers is better than that of a common paper core laminate, wherein the common paper core laminate is prepared by directly brushing flame-retardant paint on the outer side of a paper core; the characteristics of the long fibers enable the paper core layer board 1 to have better toughness, and under the same bending moment, the bending resistance of the paper core layer board 1 in the embodiment is better than that of a paper core made of mixed fibers, wherein the mixed fibers comprise long fibers and short fibers, the ratio of the parts of the long fibers to the parts of the short fibers is not the exact ratio, and the bending resistance of the paper core in the same batch is different.
S7: taking out the flame-retardant short fibers, mixing the flame-retardant short fibers and the papermaking auxiliary agent according to the part ratio of 8:1, and carrying out papermaking, squeezing, drying, surface sizing and drying to obtain a flame-retardant laminate 2; the gaps among the flame-retardant short fibers are more, and the retained flame retardant is more, so that the flame retardant has better flame-retardant effect.
S8: three paper core laminates 1 are respectively defined as a side paper core laminate 102 and a middle paper core laminate 101, a plurality of silencing holes are uniformly drilled in the side paper core laminate 102, the diameter of each silencing hole is 1.5mm, the silencing holes are arranged in the side paper core laminate 102 in a wave shape, a silencing cotton layer is covered on the side surface of the side paper core laminate, the thickness of the silencing cotton layer is 1mm, and the side paper core laminates 102 are adhered to two sides of the middle paper core laminate 101;
s9: the side surfaces of the side paper core laminates 102 are respectively and correspondingly bonded with the flame-retardant laminate 2; the combined use of the side-position paper core layer board 102 and the middle-position paper core layer board 101 greatly improves the overall toughness and flame retardant capability, and the use of the silencing holes and the silencing cotton enables the side-position paper core layer board 102 and the middle-position paper core layer board 101 to have a certain sound insulation effect, so that even if a noise source is placed in the kraft liner board, a certain silencing effect can be achieved. It can be appreciated that this design can be applied to the side of stereo set for keep apart stereo set shell body and sound production module, make the sound that the stereo set sent can not spill over from the side of shell body as far as possible, if take place to fire, fire-retardant effect can be from the side protection sound production module of shell body to a certain extent avoid burning out.
S10: the outer side of the flame-retardant laminate 2 is bonded with a protective plate, the protective plate is coated with elastic paint, and the protective plate coated with elastic paint is called a buffer laminate 3. The protective plate can be made of a common corrugated paperboard layer, and is coated with an elastic coating, wherein the elastic coating is prepared by taking synthetic resin emulsion as a base material, pigment, filler and auxiliary agent, and after a certain thickness is applied, the dry film thickness is greater than or equal to 150 mu m, and the elastic coating has elastic functional coating for covering tiny cracks generated by bending of a base material, and can further improve the overall toughness of the kraft liner board.
