Description

Colored polypropylene fiber and preparation method thereof Technical Field
The invention relates to a colored polypropylene fiber with good oxidation resistance and a preparation method thereof.
Background
Polypropylene fibers are widely used because of their light weight and quick drying. However, polypropylene is subject to oxidative decomposition under the action of light and heat to generate alkyl radicals, and the reaction continues. By this chain reaction called autoxidation cycle, polypropylene is autooxidatively cracked, and at the same time, the cracking reaction is an exothermic reaction, and the polypropylene is melted, fuming or even burned under the action of self-heating.
In order to reduce the problem of oxidative heat generation of polypropylene, the main measure in the prior art is to add an antioxidant. For example, patent CN02112743.3 discloses a transparent polypropylene composition, in which phenolic and phosphonite or sulfuric acid antioxidants are added to improve the antioxidant property of polypropylene. However, unlike transparent polypropylene, colored polypropylene has poorer oxidation resistance, and colorants such as carbon black and the like in colored polypropylene have adsorption effect on antioxidants, which affects the distribution of the antioxidants in the polypropylene and weakens the effect of the antioxidants.
Disclosure of Invention
The invention aims to provide a colored polypropylene fiber with good oxidation resistance.
The technical solution of the invention is as follows:
the colored polypropylene fiber contains a component a of hindered phenol antioxidants and a component b of phosphite antioxidants and/or a component c of hindered amine antioxidants, wherein the component a accounts for 800-15000 ppm of the colored polypropylene fiber, preferably 1000-8000 ppm of the colored polypropylene fiber; when the component b is contained, the weight ratio of the component b to the component a is less than 0.80, preferably more than or equal to 0.20 and less than 0.80; when the component c is contained, the component c accounts for 4000 to 50000ppm, preferably 4000 to 20000ppm of the colored polypropylene fiber.
The colored polypropylene fiber preferably contains the component a, the component b and the component c at the same time.
The component a is preferably at least one of pentaerythritol tetrakis [ β - (3, 5-di-tert-butyl-4-hydroxyphenyl) propionate ], octadecyl β - (3, 5-di-tert-butyl-4-hydroxyphenyl) propionate, 1,3, 5-trimethyl-2, 4, 6-tris (3, 5-di-tert-butyl-4-hydroxybenzyl) benzene or 1,3, 5-tris (4-tert-butyl-3-hydroxy-2, 6-dimethylbenzyl) -1,3, 5-triazine-2, 4,6- (1H,3H,5H) -trione as a hindered phenol antioxidant.

The component c hindered amine antioxidant is preferably poly { [6- [ (1,1,3, 3-tetramethylbutyl) amino group]]-1,3, 5-triazine-2, 4- [ (2,2,6, 6-tetramethyl-piperidyl) imino group]-1, 6-hexamethylene-bis [ (2,2,6, 6-tetramethyl-4-piperidyl) imino group]}; poly (4-hydroxyethyl-2, 2,6, 6-tetramethyl-1-piperidineethanol) succinate; n is a radical of,N,N,N-tetrakis (2, 4-bis ((N-1, 2,2,6, 6-pentamethyl-4-piperidinyl) -N-butylamino) -1,3, 5-triazin-6-yl) -4, 7-diazodecane-1, 10-diamine; bis (1-undecane-2, 2,6, 6-tetramethylpiperidin-4-yl) carbonate or 1,3, 5-triazine-2, 4, 6-triamine-N-N' - [1, 2-ethanediylbis [ [ [ [ [4, 6-bis [ butyl (1,2,2,6, 6-pentamethyl-4-piperidyl) amino ] amino]-1,3, 5-Tridumosin-2-yl]Imino radical]3, 1-propanediyl radical]]-bis [ N '-N "-dibutyl-N', N" -bis (1,2,2,6, 6-pentamethyl-4-piperidinyl)]At least one of (1).
The invention also discloses a preparation method of the colored polypropylene fiber, which comprises the steps of uniformly mixing polypropylene with the component a hindered phenol antioxidant and the component b phosphite antioxidant and/or the component c hindered amine antioxidant, extruding and granulating to obtain a colored polypropylene mixture, and carrying out melt spinning on the colored polypropylene mixture to obtain the colored polypropylene fiber, wherein the component a accounts for 800-15000 ppm of the polypropylene mixture, and when the component b is added, the weight ratio of the component b to the component a is less than 0.80; when the component c is added, the component c accounts for 4000-50000 ppm of the polypropylene mixture.
The colored polypropylene fiber has excellent oxidation resistance, less cracking heat and wide application.
Detailed Description
Polypropylene itself is unstable in structure, easily oxidized, and the oxidation process is accompanied by a heat generation phenomenon, thus affecting the safety of products using polypropylene fibers. Although the addition of antioxidants can improve the antioxidant properties of polypropylene, for colored polypropylene containing colorants, which are less resistant to oxidation, the effect of the antioxidants can be affected due to the adsorption of the colorants to the antioxidants. And excessive addition of the antioxidant can reduce the physical properties of the polypropylene product and can cause the colored polypropylene product to be easily yellowed.
The colored polypropylene fiber provided by the invention has excellent oxidation resistance, and the physical properties of the fiber, such as strength, are also good, and yellowing is not easy to occur.
The colored polypropylene fiber contains a component a of hindered phenol antioxidant and a component b of phosphite antioxidant and/or a component c of hindered amine antioxidant, wherein the component a accounts for 800-15000 ppm of the colored polypropylene fiber. When the polypropylene fiber contains component b, the weight ratio of component b to component a is less than 0.80; when the polypropylene fiber contains the component c, the component c accounts for 4000-50000 ppm of the colored polypropylene fiber.
During the oxidative decomposition of polypropylene, alkyl radicals and peroxy radicals are formed, wherein the alkyl radicals are further oxidized to peroxy radicals. The peroxide free radical is unstable, and a part of the peroxide free radical can further generate hydroperoxide to accelerate the oxidative decomposition of the polypropylene. The component a hindered phenol antioxidant can capture peroxide free radicals, the component b phosphite antioxidant can capture hydroperoxides, and the component c hindered amine antioxidant can capture peroxide free radicals and alkyl free radicals simultaneously.
In order to obtain colored polypropylene fibers with certain oxidation resistance, the content of the component a hindered phenolic antioxidant in the fibers must be more than 800ppm, otherwise, the oxidation resistance of the colored polypropylene fibers is difficult to improve after most of the component a hindered phenolic antioxidant is adsorbed by the colorant in the fibers, and meanwhile, the oxidation resistance of the colorant is poor, which can further deteriorate the oxidation resistance of the colored polypropylene fibers. When the content of the hindered phenol antioxidant of the component a in the colored polypropylene fiber is higher than 15000ppm, the preparation cost of the colored polypropylene fiber is increased, and meanwhile, the excessive hindered phenol antioxidant of the component a can be oxidized in the air to generate quinone compounds, so that the colored polypropylene fiber is yellowed.
The content of the hindered phenol antioxidant in the component a in the colored polypropylene fiber is preferably 1000-8000 ppm.
The phosphite antioxidant of the component b has the function of capturing hydroperoxide, and can effectively inhibit the oxidation of the hindered phenol antioxidant of the component a in the air, thereby inhibiting the yellowing of polypropylene. In order to achieve the above effects simultaneously, the weight ratio of the component b to the component a in the colored polypropylene fiber is less than 0.80. When the weight ratio of the component b to the component a is more than or equal to 0.80, more component b phosphite antioxidant remains in the colored polypropylene fiber relative to the component a hindered phenol antioxidant, and because no hydroperoxide for catching exists, the part of the component b phosphite antioxidant does not play a role in antioxidation, but the preparation cost of the colored polypropylene fiber is increased, and meanwhile, the strength of the polypropylene fiber is reduced due to a large amount of the component b phosphite antioxidant. When the component b is a phosphite antioxidant, the weight ratio of the component b to the component a in the colored polypropylene fiber of the invention is preferably more than or equal to 0.20 and less than 0.80.
The component c is hindered amine antioxidant which has the function of capturing alkyl free radicals and peroxidation free radicals. When the content of the component c hindered amine antioxidant in the colored polypropylene fiber is lower than 4000ppm, alkyl free radicals and peroxide free radicals cannot be effectively captured, excessive alkyl free radicals can be further oxidized into peroxide free radicals, and the peroxide free radicals can generate a large amount of hydroperoxide, so that the oxidation of polypropylene is further accelerated, and the oxidation resistance of the colored polypropylene fiber cannot be improved. When the content of the hindered amine antioxidant in the component c is more than 50000ppm, the strength of the colored polypropylene fiber is reduced, and the cost is increased. When the component c is a hindered amine antioxidant, the content of the component c in the colored polypropylene fiber is preferably 4000-20000 ppm.
The colored polypropylene fiber contains a component a of hindered phenol antioxidant, a component b of phosphite antioxidant and/or a component c of hindered amine antioxidant, and three conditions exist: the first component contains a component a and a component b, the second component contains a component a and a component c, and the third component contains a component a, a component b and a component c. The third case is preferable, namely, the colored polypropylene fiber simultaneously contains a component a hindered phenol antioxidant, a component b phosphite ester antioxidant and a component c hindered amine antioxidant.
