Problems solved by technology

[0004] Aiming at the problems existing in the prior art, the present invention proposes a fly ash-reinforced microfiber degradable nonwoven material and a preparation method thereof. The metal-modified polypropylene is a degradable, high-strength, strong-absorbing, and soft, degradable non-woven material that can be used as writing paper, packaging bags, etc. through melt-blown technology, which solves the problem of the existing polylactic acid melting problem. Spray non-woven materials have problems such as low strength, poor usability alone, relatively astringent hand feeling, and low adsorption capacity.

Embodiment 1

[0020] The preparation method of the fly ash-reinforced ultrafine fiber degradable non-woven material of this embodiment is as follows:

[0021] (1) Mix 15% polylactic acid, 3% polyethylene glycol and 6% metallocene-modified polypropylene and heat it to 170°C to form a melt. The molecular weight of polyethylene glycol used is 3600-4400. Afterwards, 76% of fly ash was mixed into the melt formed by polylactic acid, polyethylene glycol and metallocene-modified polypropylene and stirred uniformly. During the stirring process, the temperature was lowered to form blended slices. The used pulverized coal The particle size of ash is 0.5 micron-300 micron;

[0022] (2) Put the blended slices into an environment with a temperature of 70°C and a vacuum of 0.05Mpa, and dry for 70 minutes;

[0023] (3) The dried blended slices are sent to the screw extruder to form a polymer melt, and then sent to the spinning die after passing through the filter and metering pump, and extruded through the spinn...

Embodiment 2

[0025] The preparation method of the fly ash-reinforced ultrafine fiber degradable non-woven material of this embodiment is as follows:

[0026] (1) Mix 18% polylactic acid, 4% polyethylene glycol, and 7% metallocene-modified polypropylene and heat to 180°C to form a melt. The molecular weight of polyethylene glycol used is 3600-4400. Afterwards, 71% of fly ash was mixed into the melt formed by polylactic acid, polyethylene glycol, and metallocene-modified polypropylene and stirred uniformly. During the stirring process, the temperature was reduced to form blended slices. The pulverized coal used The particle size of ash is 0.5 micron-300 micron;

[0027] (2) Put the blended slices into an environment with a temperature of 65°C and a vacuum of 0.05Mpa, and dry for 90 minutes;

[0028] (3) The dried blended slices are sent to the screw extruder to form a polymer melt, and then sent to the spinning die after passing through the filter and metering pump, and extruded through the spinne...

Embodiment 3

[0030] The preparation method of the fly ash-reinforced ultrafine fiber degradable non-woven material of this embodiment is as follows:

[0031] (1) Mix 21% polylactic acid, 4% polyethylene glycol and 8% metallocene-modified polypropylene and heat it to 200°C to form a melt. The molecular weight of polyethylene glycol used is 3600-4400. After that, 67% of fly ash is mixed into the melt formed by polylactic acid, polyethylene glycol and metallocene-modified polypropylene and stirred uniformly. During the stirring process, the temperature is reduced to form blended slices. The used pulverized coal The particle size of ash is 0.5 micron-300 micron;

[0032] (2) Put the blended slices into an environment with a temperature of 75°C and a vacuum of 0.05Mpa, and dry for 60 minutes;

[0033] (3) The dried blended slices are sent to the screw extruder to form a polymer melt, and then sent to the spinning die after passing through the filter and metering pump, and extruded through the spinner...

Abstract

The invention discloses a flyash-reinforced superfine fiber degradable nonwoven material and a preparation method thereof and belongs to the technical field of preparation of nonwoven materials. A filament-based fiber material is made by subjecting the main material, flyash, polylactic acid modified via polyethylene glycol and the auxiliary material, metallocene-modified polypropylene to polymer melt extrusion molding; the flyash-reinforced superfine fiber degradable nonwoven material made with the filament-based fiber material has the advantages of degradability, high strength, good size stability, high adsorbability, high porosity, good softness and the like. It is intended to solve the problem of comprehensively utilizing flyash generated in flue gas from coal combustion; the flyash-reinforced superfine fiber nonwoven material formed herein has the advantages of availability for writing, usability as packaging materials and the like.

Description

Technical field [0001] The invention relates to the field of non-woven material composites, in particular to a degradable non-woven material reinforced by fly ash with superfine fibers and a preparation method thereof. Background technique [0002] With the development of the power industry, the discharge of fly ash from coal-fired power plants has increased year by year. If it is discharged into the water system, it will block the river, and the toxic chemicals in it will also cause harm to the human body and biology. In addition, fly ash can be used as an admixture for concrete. At present, my country is one of the industrial waste residues with a large amount of fly ash. Secondly, with the improvement of people's living standards, disposable plastic bags, express bags and packaging bags are difficult to degrade, which has caused great pollution to our country's environment. A fly ash ultrafine fiber non-woven material not only uses a large amount of fly ash as a raw material...
