Embodiment 1

[0027] Put 1 part of ultrafine calcium carbonate particles and 0.02 parts of titanate coupling agent into a high-speed mixer at a speed of 1000r / min, stir and mix for 20 minutes, then add 99 parts of polyphenylene sulfide chips or powder, Keep stirring while raising the temperature, stop heating when the temperature reaches 205°C, continue stirring and cooling, and discharge to room temperature. The prepared mixture was vacuum-dried at 125°C for 12 hours, then the mixture was put into a screw extruder, and melt-spun at 320°C at a spinning speed of 700m / min. Water bath stretching, dry heat stretching at 110°C and heat setting at 180°C, the total draw ratio is 3 times, so as to obtain polyphenylene sulfide / ultrafine calcium carbonate particle composite fibers. The properties of the obtained composite fibers are shown in Table 1.

Embodiment 2

[0029] Put 3 parts of ultrafine calcium carbonate particles and 0.06 parts of titanate coupling agent into a high-speed mixer at a speed of 3000r / min, stir and mix for 25 minutes, then add 96.5 parts of polyphenylene sulfide chips or powder, Keep stirring while raising the temperature, stop heating when the temperature reaches 210°C, continue stirring and cooling, and discharge to room temperature. The prepared mixture was vacuum-dried at 125°C for 12 hours, then the mixture was put into a screw extruder, and melt-spun at 320°C at a spinning speed of 700m / min. Water-bath stretching, dry stretching at 120°C and heat setting at 180°C, the total draw ratio is 3 times, so as to obtain polyphenylene sulfide / ultrafine calcium carbonate particle composite fibers. The properties of the obtained composite fibers are shown in Table 1.

Embodiment 3

[0031] Put 5 parts of ultrafine calcium carbonate particles and 0.1 part of titanate coupling agent into a high-speed mixer at a speed of 3000r / min, stir and mix for 25 minutes, then add 95 parts of polyphenylene sulfide chips or powder, Keep stirring while raising the temperature, stop heating when the temperature reaches 270°C, continue stirring and cooling, and discharge to room temperature. The prepared mixture was vacuum-dried at 125°C for 12 hours, then the mixture was put into a screw extruder, and melt-spun at 320°C at a spinning speed of 700m / min. Water-bath stretching, dry stretching at 140°C and heat setting at 200°C, with a total draw ratio of 3 times, to obtain polyphenylene sulfide / ultrafine calcium carbonate particle composite fibers.

Abstract

The invention relates to polyphenylene sulfide (PPS) / nano-calcium carbonate mixture and a preparation method for the fiber thereof. The method includes the steps of mixing polyester slices, nano-calcium carbonate particulates, reactive monomer and other additives in a high speed mixer while rising the temperature to approximately 205 DEG C so as to enable the polyphenylene sulfide slices to intenerate and the nano-calcium carbonate and other additives to be evenly adhibitted onto the polyphenylene sulfide slices, without heavy conglutination between the particles on the polyphenylene sulfide slices. The polyphenylene sulfide (PPS) / nano-calcium carbonate mixture prepared through the method has excellent processability and can be made into textile fiber, thin film or reinforcement plastics by means of melt blown or melt spinning process. The invention can greatly reduce the production cost and bring good economic benefits. The polyphenylene sulfide(PPS) / nano-calcium carbonate mixture has good thermal stability, flame retardancy, chemical corrosion resistance and good mechanical property and spinning property; therefore the polyphenylene sulfide(PPS) / nano-calcium carbonate mixture is widely applicable to the industrial sectors like chemical industry, light industry and mechanical industry, and is particularly good for accelerating the popularization and application of high-temperature house-bag dust removal. The preparation method has the advantages of simple process, easy control, low cost, short production period, environment friendly and particularly being applicable to the industrial production.

Description

technical field [0001] The invention belongs to the field of composite fibers, in particular to a composite fiber of polyphenylene sulfide / ultrafine calcium carbonate particles and a preparation method thereof. Background technique [0002] Polyphenylene sulfide fiber has excellent thermal stability, flame retardancy, chemical corrosion resistance and good mechanical and textile properties, so it is widely used as high-temperature filtration in industries such as cement, papermaking, steel, coal-fired power plants, and waste incineration plants. Dust removal material. However, due to the late start of the production technology of polyphenylene sulfide fiber in my country and the technical blockade of foreign countries, most of polyphenylene sulfide mainly depends on imports, which makes the market price of polyphenylene sulfide always high. [0003] Polymer / inorganic particle composites are a research hotspot in the field of materials in recent years. The addition of inorga...
