Problems solved by technology

[0004] However, if the secondary fiber of printed paper and cardboard is used in the midsole board for shoes, its swelling ability and plasticity will decrease, resulting in a significant decrease in the folding resistance of the finished product. Increase, the increase in the number of cycles, these characteristics will be more obvious

preparation example Construction

[0016] A method for preparing midsole boards for shoes, comprising mixing 45-55 parts by weight of fiber pulp and 45-55 parts by weight of bleached kraft wood pulp, and adjusting the mixed pulp to an online concentration of 2.5-3.5 wt%. After the first press, add 0.5-1 parts by weight of dry strength agent for pre-impregnation, and then perform the second press to adjust the pulp after the second press. The dryness of the material is 45-50%, and then the slurry is impregnated, and after the impregnation, the third pressing process is performed to obtain a board, and the glue absorption amount of the board is 30-40% of the mixed slurry. %.

[0017] As can be seen from the foregoing description, the beneficial effects of the present invention are:

[0018] (1) Add fiber pulp raw materials to bleached kraft wood pulp. Fiber pulp can be obtained from waste cardboard, thereby partially replacing bleached kraft wood pulp as the raw material for midsole boards for shoemaking. It is ...

Embodiment 1

[0040] The preparation method of the midsole plate for shoes of the present embodiment comprises the following steps:

[0041] 1. According to the total mass fraction of 100%, it includes the following components: mix the fiber pulp of waste cardboard and 45% bleached kraft wood pulp accounting for 45% of the total mass fraction, and adjust it into a papermaking pulp with an online concentration of 2.5% ;

[0042] 2. Add a sizing agent (one of dispersed loose glue, AKD, etc.) in the slurry tank, and the dosage is 0.5% for the slurry, and carry out preliminary internal sizing to improve the water resistance;

[0043]3. Add a wet strength agent (one of PPE, cationic polyacrylamide, PAE, melamine formaldehyde resin, etc.) to the head box, and the dosage is 0.5% to the pulp to ensure that the cardboard has a certain wet strength;

[0044] 4. Use a vacuum press roller for the first pressing treatment, pre-impregnate after the first pressing treatment, add a dry strength agent (gua...

Embodiment 2

[0049] The preparation method of the midsole plate for shoes of the present embodiment comprises the following steps:

[0050] 1. According to the total mass fraction of 100%, it includes the following components: mix the fiber pulp of waste cardboard and 45% bleached kraft wood pulp accounting for 55% of the total mass fraction, and adjust it into a papermaking pulp with an online concentration of 3.5%. ;

[0051] 2. Add a sizing agent (one of dispersed loose glue, AKD, etc.) in the slurry tank, and the dosage is 1% for the slurry, and carry out preliminary internal sizing to improve the water resistance;

[0052] 3. Add a wet strength agent (one of PPE, cationic polyacrylamide, PAE, melamine formaldehyde resin, etc.) to the head box, and the dosage is 2% to the pulp to ensure that the cardboard has a certain wet strength;

[0053] 4. Use a vacuum press roller for the first pressing treatment, pre-impregnate after the first pressing treatment, add a dry strength agent (guar ...

Abstract

The invention relates to an insole board for a shoe. The insole board comprises, by weight, 45-55 parts of fiber paper pulp and 45-55 parts of bleached sulphate wood pulp. The net mounting concentration of papermaking slurry obtained after the fiber paper pulp and the bleached sulphate wood pulp are mixed ranges from 2.5 wt% to 3.5 wt%. The invention further relates to a preparation method of the insole board for the shoe. The insole board for the shoe has the advantages of being low in tightness, light and soft in material, good in dimensional stability, good in anti-folding performance, good in internal bonding strength, good in surface wet abrasion resistance and good in punching performance during processing.

Description

technical field [0001] The invention relates to regenerated fiber technology, in particular to a midsole plate for shoes and a preparation method thereof. Background technique [0002] Shoe midsoles contain natural fibers, synthetic fibers and resins. Bleached kraft pulp is the main raw material for shoe midsoles. Because shoe midsoles have high requirements for forming, bleached kraft pulp can maintain a good paper width. It has become the main raw material for shoe midsole due to its excellent papermaking performance, but if only this kind of pulp is used, the appearance of the finished product cannot meet the customer's requirements due to its small number of fine fibers. [0003] As the market demand for midsole boards for shoes is increasing, the demand for wood pulp is also increasing. The production of wood pulp needs to consume a lot of forest resources, which will destroy the ecological balance. Therefore, due to the growing awareness of domestic environmental prote...
