Problems solved by technology

First of all, mulch or convenience bags made of plastic materials have poor tensile strength; secondly, petrochemical resources are facing a state of over-exploitation, and the regeneration speed of this resource is slow, so it is facing the trend of resource depletion; in addition, using this material to prepare The plastic film or convenience bag is difficult to degrade, so it causes a lot of pollution to the environment

Embodiment 1

[0019] Example 1 Preparation of chemical fiber degradable mulch film

[0020] Preparation of recycled cotton

[0021] Put the old clothes into the pool and soak them in hydrogen peroxide with a content of 27% for 24 hours to achieve the effect of bleaching, sterilization and disinfection. It is then transported to the material selection machine to separate the hard objects and iron nails and other sundries, and then shredded by the shredder, and then deducted into 20-degree fibers by the deduction machine, and combed into the recycled cotton by the card sliver for use.

[0022] The regenerated cotton with a mass fraction of 30% and the chemical fiber with a mass fraction of 70% are mixed together with a high-consistency hydraulic pulper and stirred evenly. After reaching the standard, they are put into the feed well; and then sent to the 450-type double-disc refiner by the material pump. The machine reaches the deduction degree of 32 degrees; it is then sent to the Gaonong Li...

Embodiment 2

[0023] Example 2 Preparation of chemical fiber degradable mulch film

[0024] Preparation of recycled cotton

[0025] Using old quilt as raw material, the preparation process of regenerated cotton is the same as that of Example 1.

[0026] The above-mentioned recycled cotton with a mass fraction of 40% and chemical fiber with a mass fraction of 60% are mixed together with a high-consistency hydraulic pulper and stirred evenly. After reaching the standard, put it into the material well; then use the material pump to send it into the 450-type double-disc refiner. The machine reaches a deduction degree of 35 degrees; it is then sent to the Gaonong Lixin pressure screen for screening and then sent to the material pool, and the slag is recovered and then processed to meet the standard for reuse. After screening, the qualified material is sent to the dispersing machine for dispersing, and then sent to the paddle tank, adding 10% wet strength agent and mixing with a propeller. , th...

Embodiment 3

[0027] Example 3 Preparation of chemical fiber degradation convenient bag film

[0028] Preparation of recycled cotton

[0029] Taking the leftovers of the quilt factory as the raw material, the preparation process of the regenerated cotton is the same as that of the preparation method in Example 1.

[0030] The above-mentioned recycled cotton with a mass fraction of 35% and a chemical fiber with a mass fraction of 65% are mixed and stirred together with a high-consistency hydraulic pulper. After reaching the standard, they are put into the well; The machine reaches a deduction degree of 35 degrees; it is then sent to the Gaonong Lixin pressure screen for screening and then sent to the material pool, and the slag is recovered and then processed to meet the standard for reuse. After screening, the qualified material is sent to the dispersing machine for dispersing, and then sent to the paddle tank, adding 9% wet strength agent and mixing with the propeller. , the horizontal a...

Abstract

The invention discloses a chemical fiber degradable film and a preparation method and application thereof. The chemical fiber degradable film of the present invention uses regenerated cotton with a mass fraction of 30-40% and chemical fiber with a mass fraction of 60-70% as raw materials, and undergoes mixing, stirring, disc grinding, screening, dispersing, spraying, extrusion, and drying. , Hanging film, calendering and rewinding. The invention utilizes all kinds of old clothes, old quilts, old mattresses, and leftovers cut by garment factories, which is not only environmentally friendly but also makes wastes valuable for use. It can be used as a covering film, and can also process various types of convenience bags. , good quality, and under the conditions of wind, sun and rain, it will not degrade for 6 to 8 months, prolonging the degradation time. The preparation method of the chemical fiber degradable film of the present invention adopts a one-machine film-forming process, saves fuel, electricity, labor, low cost, low cost, market competitiveness, and is well recognized by farmers and consumers.

Description

technical field [0001] The present invention relates to the technical field of degradable film production and processing, in particular to a chemical fiber degradable film and its preparation method and application. Background technique [0002] At present, mulch films or instant bags in the domestic market are generally made of plastic materials, and plastic materials are generally prepared from petrochemical raw materials. Therefore, such mulch films or instant bags have three defects. First, the mulch or convenient bag made of plastic materials has poor tensile strength; secondly, the petrochemical resources are facing the state of over-exploitation, and the regeneration of this resource is slow, so it faces the trend of resource depletion; in addition, the use of this material to prepare It is difficult to degrade the mulch film or the convenient bag, so it will cause great pollution to the environment. Therefore, the use of degradable and easy-to-regenerate materials w...
