Abstract
The invention discloses a method of a high intensity anti-aging polypropylene flat wire, which uses polypropylene, polyethylene, ethylene-vinylacetate copolymer, hindered amine-770, nano-sized CaCO3 and ultraviolet absorber 1001 as raw materials; the flat wire is obtained after the steps of agitation and preheat which aim at moisture elimination, polymerization under high temperature, air exhaust, pressing diaphragms, cooling, dissecting unfinished wire, stretching, heating and forming. The toughness of the flat wire is improved as ethylene-vinylacetate copolymer modifying agent is used for copolymerization; the falling-proof strength of the flat wire is enhanced by adding nano-sized CaCO3 filler; the oxidation is prevented and restrained by adding the hindered amine-770; an ultraviolet absorber is used for absorbing ultraviolet absorption, thus efficiently preventing the oxidation caused by illumination of ultraviolet from happening. The method solves the problems of unsatisfactory weather-ability, inferior toughness, low strength, short service life, and the like existing in the packing bags weaved with polypropylene flat wire using the prior art, and all the technical targets of the excellent product obtained from the modified polypropylene exceed the national standards.
Description
Technical field
The invention belongs to the polypropylene flat-filament production technical field, relate to a kind of production method that is used to work out the high-strength and ageing resistance polypropylene flat yarn of packaging bag.
Background technology
The packaging bag of the polypropylene flat-filament establishment that conventional art is produced, weatherability is poor, occur easily hardening at north of china in winter, problem such as embrittlement, demoulding, peeling, fracture, in south because summer temperature height, strong, the ultraviolet penetration power of illumination are strong, problem such as cause easily that woven bag is aging, burn into poor toughness, intensity low service life is short had not only been wasted but also contaminated environment.
Summary of the invention
There are problems such as weatherability is poor, poor toughness, intensity is low, service life is short in the packaging bag that the objective of the invention is to solve the polypropylene flat-filament establishment that prior art produces, and a kind of production method of high-strength and ageing resistance polypropylene flat yarn is provided.
The object of the present invention is achieved like this: the method for high-strength and ageing resistance polypropylene flat yarn of the present invention is finished by following step:
1), batching: press the mass fraction proportioning, 100 parts of polypropylene, 6 parts of polyethylene, 3 parts of ethene-vinyl acetate copolymers, hindered amine-770 0.3 part, nanometer CaCO
32 parts, ultra-violet absorber-1,001 0.15;
2), stir preheating: above-mentioned raw materials is added in the proportioning machine, carry out full and uniform mixing and preheating, make its temperature reach 70 ± 1 ℃ and remove tide;
3), polymerization: mixed material being transported to temperature through feeding belt is in 245-290 ℃ the barrel, makes it fusion and carries out polymerisation, forms copolymer;
4), exhaust: above-mentioned copolymer carries out exhaust through the screw rod rotatable propeller, and the copolymer after the modification is combined closely;
5), squeeze diaphragm: the copolymer after exhaust is sent into wire drawing unit extruder filter screen district and die head district partly, extrudes the modified polypropene diaphragm;
6), diaphragm cooling: polypropylene diaphragm is immersed water temperature in 40-45 ℃ tank, cool off;
7), cut open the embryo silk: cooled polypropylene diaphragm cuts open into the embryo silk through wire dissecting machine, is drawn into the thick embryo silk of 0.045～0.065mm;
8), add HEAT SETTING: under 110 ℃, add HEAT SETTING, promptly get high-strength and ageing resistance polypropylene flat yarn.
The inventive method is carried out modification by copolymerization because polypropylene, polyethylene are added ethene-vinyl acetate copolymer modifier by a certain amount of proportioning, can reach performance complement, improves its toughness; Add proper amount of nano CaCO
3Filler is in order to strengthen its anti-intensity of falling; Add hindered amine-770 in order to stop and to suppress the generation of oxidation reaction; Add an amount of ultra-violet absorber in order to absorb ultraviolet ray and its energy is transformed into harmless heat energy and discharges, thereby effectively stop the caused oxidation reaction of ultraviolet illumination, there are problems such as weatherability is poor, poor toughness, intensity is low, service life is short in the packaging bag that has solved the polypropylene flat-filament establishment of prior art production, by the product of polypropylene modification obtained performance excellence, every technical indicator is all above national standard.
The specific embodiment
Embodiment 1 gets 100 parts of polypropylene, 6 parts of polyethylene, 3 parts of ethene-vinyl acetate copolymers, hindered amine-770 0.3 part, nanometer CaCO by proportion by weight
32 parts, ultra-violet absorber is prepared burden for 1,001 0.15 parts, in proportioning machine, carry out full and uniform mixing and tide is removed in preheating, make its temperature reach 70 ℃, mixed material being delivered to temperature through feeding belt is in 245 ℃ the barrel, make it to implement polymerisation after the fusion, form copolymer, again through the exhaust of screw rod rotatable propeller, the copolymer after the modification is combined closely, send into the filter screen district and the die head district of wire drawing unit extruder part then, extrude the modified polypropene diaphragm, immerse water temperature and in 40 ℃ tank, cool off, cut open into the embryo silk, be drawn into the thick embryo silk of 0.045mm through wire dissecting machine, under 110 ℃, add HEAT SETTING, promptly get high-strength and ageing resistance polypropylene flat yarn.
Embodiment 2 is according to embodiment 1, and the temperature of barrel is 290 ℃, and the coolant water temperature in the tank is 45 ℃, and the thickness of embryo silk is 0.065mm.
Embodiment 3 is according to embodiment 1, and the temperature of barrel is 260 ℃, and the coolant water temperature in the tank is 42 ℃, and the thickness of embryo silk is 0.055mm.
