Embodiment 1

[0039] In a 10-liter high-speed mixer (SHR-10A, the same below), add 720 grams of light calcium carbonate with a particle diameter of 60-90nm and 1080 grams of heavy calcium carbonate with a particle diameter of 70%≤3 μm, turn on high speed, stir and heat up to Keep at 110°C for 10 minutes to remove moisture. Add the stearic acid of 3.6 grams, stop after stirring for 15 minutes, be cooled to below 70 ℃. Then add 36 grams of aluminate coupling agent, stir at high speed for 20 minutes, and stop. Add 1200 grams of Y3700pp, 25 grams of polysiloxane, 8 grams of antioxidant 1010, 16 grams of antioxidant 168, 9 grams of calcium stearate, 120 grams of polypropylene wax, and 9 grams of HE86, and take it out after stirring for 10 minutes. Bagging.

Embodiment 2

[0041] In a 10-liter high-speed mixer, add 300 grams of light calcium carbonate with a particle size of 60-90nm and 1200 grams of heavy calcium carbonate with a particle size of 70%≤3μm, stir and heat up to 110°C for 10 minutes, and then add 4.5 grams of calcium carbonate Stearic acid, stirring stopped after 20 minutes. After cooling to below 70°C, 18 grams of titanate coupling agent was added, and the stirring was stopped after 15 minutes. Add 120 grams of maleic anhydride grafted pp, 1200 grams of Y3700pp, 20 grams of ethylene bis stearic acid amide, 8 grams of antioxidant 1010, 8 grams of antioxidant 168, 9 grams of calcium stearate, 377 grams of polypropylene wax , 6 grams of HE86, stirred for 10 minutes and removed. Bagging.

Embodiment 3

[0043]In a 10-liter high-speed mixer, add 625 grams of light calcium carbonate with a particle size of 60-90nm and 1875 grams of heavy calcium carbonate with a particle size of 80%≤1.6μm, stir and heat up to 110°C for 10 minutes, and then add 5.4 grams Stearic acid, stop stirring after 15 minutes, and cool to below 70°C. Then add 188 grams of nano-montmorillonite with a lamination thickness of less than 25 nm and a diameter / thickness ratio of 200, and 85 grams of aluminate coupling agent, and stir at high speed for 20 minutes before stopping. Add 1250 grams of S2040pp, 250 grams of polyethylene wax, 150 grams of polypropylene wax, 8 grams of antioxidant 1010, 8 grams of antioxidant 168, 19 grams of silicone lubricant, 8 grams of zinc stearate. Remove after stirring for 8 minutes. Bagging.

Abstract

A preparation method of inorganic-material-containing polypropylene composite master batch which is used in polypropylene fiber: composing polypropylene, inorganic material, additive A, B, C, D, E, specifically, the inorganic material is one or the compound of kaolin, calcium carbonate and montmorillonite with submicron-, micron- and nano-scales; the additive A is dispersant, B is lubricant, C is antioxidant, D is heat stabilizer, E is modifier; additive F is also added, which is coupling agent. As the coupling agent is added in compound by the method of the present invention, and the compatible effect of various components, there is a good compatibility between inorganic material and polypropylene resin with submicron-, micron- and nano-scales, and the dispersive property, the rheological property and the crystallization property are improved, and the spinnability is increased. The polypropylene composite master batch prepared by this method, can be used as a kind of low-cost composite master batch; being even mixed with fiber grade polypropylene according to proportions, the qualified polypropylene fiber can be produced.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a method for preparing a polypropylene composite masterbatch, a method for preparing a polypropylene composite masterbatch containing inorganic materials for polypropylene fibers Background technique [0002] Polypropylene fiber has many excellent properties, and it has a huge market in the three major fields of decoration, agriculture and clothing. The varieties of polypropylene fiber include BCF, staple fiber, filament, spunbond / meltblown nonwoven fabric, membrane split fiber, filter material, etc. [0003] Polypropylene fiber has strict requirements on the quality of raw polypropylene resin, including molecular weight and molecular weight distribution, isotacticity, rheological properties of melt, crystallization properties, etc., especially the content of impurities or ash. Excessive impurity content can easily lead to an increase in the filter pressure in the component during the me...
