Embodiment 1

[0029] The hollow elastic fiber masterbatch of this embodiment consists of the following components by weight percentage:

[0030] PP plastic 76%, toughening agent 20%, elastic masterbatch 1%, soft masterbatch 3%.

[0031] PP has a melting point of 164-170°C and a density of 0.91-0.92g / cm3.

[0032] The toughening agent is one or more of high-density polyethylene, ethylene-vinyl acetate copolymer, and acrylonitrile-butadiene-styrene copolymer.

[0033] The soft masterbatch is SOPP273, the bulk density of SOPP273 is 520-560kg / m3; the melt index (230°C, 2.16kg) is 120-150g / 10min, and the specific melt index can be in accordance with the ASTM D1238 standard; the moisture content is <600ppm.

[0034] Elastic masterbatch is SR-558 elastic resin.

[0035] Its preparation method is as follows:

[0036] (1) take each component by above-mentioned percentage by weight;

[0037] (2) Put the PP, toughening agent, elastic masterbatch and soft masterbatch weighed in the step (1) into a ...

Embodiment 2

[0040] The hollow elastic fiber masterbatch of this embodiment consists of the following components by weight percentage:

[0041] PP plastic 77%, toughening agent 15%, elastic masterbatch 3%, soft masterbatch 5%.

[0042] PP has a melting point of 164-170°C and a density of 0.91-0.92g / cm3.

[0043] High-density polyethylene is used as the toughening agent. The density of HDPE is in the range of 0.940-0.976g / cm3, and the molecular weight range is 40000-300000. The weight-average molecular weight roughly corresponds to the range of the melt index, from 100-0.029g / 10min 230°C, 2.16kg). Higher Mw (lower melt index MI) enhances melt strength, better toughness. Toughener.

[0044] The soft masterbatch is SOPP273, the bulk density of SOPP273 is 520-560kg / m3; the melt index (230°C, 2.16kg) is 120-150g / 10min, and the specific melt index can be in accordance with the ASTM D1238 standard; the moisture content is <600ppm.

[0045] The elastic masterbatch is a metallocene modified pro...

Embodiment 3

[0051] The hollow elastic fiber masterbatch of this embodiment consists of the following components by weight percentage:

[0052] 80% PP plastic, 15% toughening agent, 3% elastic masterbatch, 5% soft masterbatch.

[0053] PP has a melting point of 164-170°C and a density of 0.91-0.92g / cm3.

[0054] The toughening agent is one or more of high-density polyethylene, ethylene-vinyl acetate copolymer, and acrylonitrile-butadiene-styrene copolymer.

[0055] The soft masterbatch is SOPP273, the bulk density of SOPP273 is 520-560kg / m3; the melt index (230°C, 2.16kg) is 120-150g / 10min, and the specific melt index can be in accordance with the ASTM D1238 standard; the moisture content is <600ppm.

[0056] Elastic masterbatch is APU55D elastic resin.

[0057] Its preparation method is as follows:

[0058] (1) take each component by above-mentioned percentage by weight;

[0059] (2) Put the PP, toughening agent, elastic masterbatch and soft masterbatch weighed in the step (1) into a ...

Abstract

The invention discloses a masterbatch for hollow elastic fibers. The masterbatch comprises the following components, in percentages by weight: 70-80% of PP, 15-20% of a toughening agent, 1-3% of a soft masterbatch, and 3-5% of an elastic masterbatch. The invention also discloses a preparation method of the masterbatch for the hollow elastic fibers. The method comprises the following steps: (1) weighing the PP, the toughening agent, the soft masterbatch and the elastic masterbatch according to the formula of the masterbatch for the hollow elastic fibers described in the claim 1; (2) adding the PP, the toughening agent, the soft masterbatch and the elastic masterbatch weighed in the step (1) into a mixer, and performing uniform mixing to obtain a mixture; and (3) adding the mixture obtained in the step (2) into a twin-screw extruder, and performing melt extrusion to obtain the masterbatch for the hollow elastic fibers.

Description

technical field [0001] The invention relates to a polymer material, in particular to a master batch for producing hollow elastic fibers and a preparation method thereof. Background technique [0002] In 2000, my country's apparent consumption of polypropylene was 4.87 million tons. In 2001, it reached 5.3 million tons, becoming the second largest consumer of polypropylene in the world. In 2003, it increased to 7.18 million tons, surpassing the United States to become the world's largest consumer. In recent years, the application of PP in my country has continued to diversify. In addition to maintaining a certain growth in traditional woven bags, PP used in the fields of industry, automobiles and home appliances has grown rapidly, especially fiber-grade PP, biaxially oriented PP film (BOPP), household The demand for special materials for electrical appliances and special materials for automobiles has greatly increased. Although most of these products can be provided domestica...
