Problems solved by technology

[0007] Regardless of whether it is monomer polymerization or low-melt-index polypropylene adding additives, the high-MFR polypropylene raw material is first prepared, and then the high-MFR polypropylene is used to prepare the melt-blown non-woven fabric, which is a long production process, long working hours, and high cost. High, not conducive to improving production efficiency

Embodiment 1

[0053] Additive A1 was prepared by mixing 2% fatty acid amide and 98% bis-tert-butyl peroxide in a weight ratio.

[0054] Add additive A1 to the polypropylene raw material with low melt index, put it into the extruder to heat and melt it, so that the additive A1 reaches 1.8% of the total proportion of the melt, and extrude it from the spinneret hole on the die through the melt distribution flow channel, The hot air flow is super-drawn, and the ultra-fine fibers are cooled and solidified, deposited on the net collection device, and wound into a net to obtain a melt-blown non-woven fabric. Then make 52g / m2 by conventional process method 2 SMMS non-woven fabric B1.

Embodiment 2

[0056] The additive A1 in Example 1 is added to polyolefin for mixing and kneading, and the mixed masterbatch is obtained through the processing processes such as extruder and other equipment metering, mixing, melting, extrusion, pelletizing, etc., and the mixed masterbatch contains 30% The effective component mixture of additive A2 is obtained.

[0057] Add additive A2 to the polypropylene raw material with low melt index, put it into the extruder to heat and melt it, so that the additive A2 reaches 1.8% of the total proportion of the melt, and extrude it from the spinneret hole on the die through the melt distribution flow channel, The hot air flow is super-drawn, and the ultra-fine fibers are cooled and solidified, deposited on the net collection device, and wound into a net to obtain a melt-blown non-woven fabric. Then make 52g / m2 by conventional process method 2 SMMS non-woven fabric B2.

Embodiment 3

[0059] Add fatty acid amide and bis-tert-butyl peroxide into polyolefin for mixing and kneading respectively, and obtain fatty acid amide masterbatch and bis-tert-butyl peroxide through extruder and other equipment metering, mixing, melting, extrusion, pelletizing and other processing processes. Peroxide masterbatch, the fatty acid amide masterbatch contains 30% fatty acid amide, and the bis-tert-butyl peroxide contains 30% bis-tert-butyl peroxide. Additive A3 was prepared by mixing 2% fatty acid amide masterbatch and 98% bis-tert-butyl peroxide masterbatch by weight.

[0060] Add additive A3 to the polypropylene raw material with low melt index, put it into the extruder to heat and melt it, so that the additive A3 reaches 1.8% of the total proportion of the melt, and extrude it from the spinneret hole on the die through the melt distribution channel, The hot air flow is super-drawn, and the ultra-fine fibers are cooled and solidified, deposited on the net collection device, a...

Abstract

The invention discloses an additive for producing melt-blown nonwoven fabrics. The additive is prepared from 0.05-5wt% of fatty acid amide and 95-99.5wt% of di-tert-butyl peroxide. The invention also discloses a use method of the additive for producing melt-blown nonwoven fabrics. An additive and low-melt index polypropylene raw material mixture contains 0.3-10% of the additive. The additive can improve the fluidity of the melt blow raw material, and can be added to low-melt index polypropylene in order to directly produce the melt-blown nonwoven fabrics, so the product quality is ensured, the flow is simplified, the cost is saved, and the efficiency is increased.

Description

technical field [0001] The invention relates to the field of textiles, in particular to an additive for producing melt-blown non-woven fabrics, and correspondingly, also relates to a method for using the additive. Background technique [0002] After experiencing SARS in 2003 and avian influenza A (H5N1) in 2009, melt-blown non-woven fabrics are recognized by most people because of their good filtration performance and their wide application in disposable masks. In recent years, because of its good filtration performance, melt-blown non-woven fabrics have not only been vigorously promoted in the application of masks, but also in industries (such as automobiles, oil, air conditioners, protective clothing, etc.), medical treatment (such as surgical gowns, etc.), It has also been widely used in hygiene (such as leak-proof partitions of baby diapers, etc.), and life (such as air filtration, water filtration, etc.). With the improvement of people's living standards and the contin...
