FIG. 2 is an infrared spectrum provided by an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
The invention provides an age resister master batch for polypropylene fibers, which comprises 20-40 wt% of polypropylene, 4-56 wt% of LLDPE, 20-40 wt% of POE, 3-9 wt% of antioxidant and 1-7 wt% of ultraviolet absorbent.
In this embodiment, the polypropylene fiber age resister masterbatch is toughened and modified by adding LLDPE (linear low density polyethylene) and POE (ethylene-1-octene copolymer) into the polypropylene matrix, so that the toughness of the polypropylene fiber prepared by using the polypropylene fiber age resister masterbatch can be obviously improved. The mechanism of improving the toughness of the polypropylene fiber by LLDPE and POE is as follows: the two components can inhibit the crystallization of polypropylene through a synergistic effect, form microcrystals and further improve the toughness of the polypropylene fiber.
Meanwhile, the antioxidant and the ultraviolet absorber are added into the polypropylene matrix, so that the oxidation resistance and the ultraviolet radiation resistance of the polypropylene fiber prepared by using the polypropylene fiber anti-aging agent master batch can be obviously improved, and the aging resistance of the polypropylene fiber is further improved. Therefore, the polypropylene fiber anti-aging agent masterbatch provided by the embodiment can improve the toughness of the polypropylene fiber and simultaneously improve the anti-aging performance of the polypropylene fiber, so that the balance between the oxidation resistance and the toughness is good, and the service life of the polypropylene fiber is prolonged.
In addition, the compatibility among polyethylene, LLDPE and POE is good, and a compatilizer is not needed, so that the preparation cost of the polypropylene fiber is reduced.
The polypropylene fiber anti-aging agent adopts a master batch structure, so that the polypropylene fiber anti-aging agent can be uniformly dispersed in a polypropylene raw material when polypropylene is prepared, and the anti-aging property and the toughness of polypropylene fibers are further improved.
In some preferred embodiments, the polypropylene is 30 wt%, the LLDPE is 30 wt%, the POE is 30 wt%, the antioxidant is 6 wt%, and the uv absorber is 4 wt%. When the weight of each component is proportioned in this way, the anti-aging performance and toughness of the polypropylene fiber anti-aging agent master batch to the polypropylene fiber can be improved to the maximum.
In some preferred embodiments, the antioxidants include antioxidant 1010 and antioxidant 168, and the weight ratio of antioxidant 1010 to antioxidant 168 is 1: 2.
In this embodiment, the antioxidant is prepared by compounding two kinds of oxidants, and the weight ratio of the antioxidant 1010 to the antioxidant 168 is 1:2, so that the polypropylene fiber prepared from the polypropylene fiber anti-aging agent masterbatch has the best antioxidant performance.
In some preferred embodiments, the ultraviolet absorber includes an ultraviolet absorber UV326 and an ultraviolet absorber UV531, and the weight ratio of the ultraviolet absorber UV326 to the ultraviolet absorber UV531 is 1: 1.
In this embodiment, the ultraviolet absorbent is prepared by compounding two oxidants, and the weight ratio of the ultraviolet absorbent UV326 to the ultraviolet absorbent UV531 is 1:1, so that the polypropylene fiber prepared from the polypropylene fiber anti-aging agent masterbatch has the best ultraviolet radiation resistance.
The application also provides polypropylene fiber anti-aging agent master batch which comprises 86-89% by weight of polypropylene, 1-4% by weight of inorganic nano particles, 3-9% by weight of antioxidant and 1-7% by weight of ultraviolet absorbent.
In this example, the specific surface area of the inorganic nanoparticles is large and the contact area with the polypropylene matrix is large by adding the inorganic nanoparticles to the polypropylene matrix. The inorganic nano particles can initiate and deflect microcracks generated in the matrix, and absorb the impact energy of the outside to the matrix, so that the toughness of the medical polypropylene fiber is improved. Specifically, the method comprises the following steps: when the medical polypropylene fiber is impacted by external force, microcracks can be generated, and when the microcracks meet the inorganic nano particles, the microcracks can deflect and initiate new cracks to absorb more impact force, so that the toughening performance of the polypropylene fiber is improved. Meanwhile, the antioxidant and the ultraviolet absorber are added into the polypropylene matrix, so that the oxidation resistance and the ultraviolet radiation resistance of the polypropylene fiber prepared by using the polypropylene fiber anti-aging agent master batch can be obviously improved, and the aging resistance of the polypropylene fiber is further improved. Therefore, the polypropylene fiber anti-aging agent masterbatch provided by the embodiment can improve the toughness of the polypropylene fiber and simultaneously improve the anti-aging performance of the polypropylene fiber, so that the balance between the oxidation resistance and the toughness is good, and the service life of the polypropylene fiber is prolonged.
In some preferred embodiments, the antioxidants include antioxidant 1010 and antioxidant 168, and the weight ratio of antioxidant 1010 to antioxidant 168 is 1: 2. The ultraviolet absorbent comprises an ultraviolet absorbent UV326 and an ultraviolet absorbent UV531, and the weight ratio of the ultraviolet absorbent UV326 to the ultraviolet absorbent UV531 is 1: 1. The beneficial effects of such an arrangement of antioxidants and UV absorbers are not described herein in detail, see above.
In some preferred embodiments, the inorganic nanoparticles are silica nanoparticles.
In the embodiment, the cost of the silica nanoparticles is relatively low, so that the cost of the polypropylene fiber anti-aging agent master batch is relatively low. Of course, in other embodiments, the inorganic nanoparticles may also be titanium dioxide nanoparticles or graphene nanoparticles, etc. Wherein the particle size of the inorganic nano particles is 50-120 nm.
The application also provides a polypropylene fiber, which comprises the polypropylene fiber anti-aging agent master batch.

| A | 3.2 | 41.2 | 38 |
| B | 7.2 | 30.7 | 23.5 |
