Description
Technical Field
The invention relates to the field of high polymer materials, in particular to a wear-resistant master batch for a polypropylene spinning material and a preparation method thereof.
Background
At present, spinning materials are mainly three materials of nylon (also called chinlon), terylene (PET/PBT) and Polypropylene (PP), wherein the PP material has the worst wear resistance, so that the application field of the PP material is limited.
The traditional method for improving the wear resistance of the PP material comprises the following steps: firstly, adding wear-resistant auxiliary agents such as polysiloxane, silicone powder, polytetrafluoroethylene powder and the like; and the second is blending with wear-resistant materials, such as UHMWPE, silicon dioxide, talcum powder and the like. The mechanism of adding the wear-resistant assistant is mainly to improve the surface properties of the PP material, such as smooth surface, surface contact angle and the like, although the method can improve the wear resistance, the surface is damaged after a certain time of force application, so that the method is ineffective, and therefore the defects of small improvement range, poor durability, high cost and the like exist. The blending mechanism with the wear-resistant material is to improve the wear resistance of the material by blending the wear-resistant material and the non-wear-resistant material, but the method needs a large amount of the wear-resistant material, which affects the spinning forming performance. In particular to a wear-resistant PP material which comprises the following components in parts by weight: 30-50 parts of PP, 5-8 parts of dispersant, 3-5 parts of cross-linking agent, 15-20 parts of compatibilization toughening agent, 10-20 parts of nano titanium dioxide and 0.5-5 parts of composite antioxidant. The method improves the wear resistance of the polypropylene material by a scheme of blending with the wear-resistant material nano titanium dioxide, but the nano titanium dioxide has high addition amount (the wear-resistant effect can be achieved only when the addition amount is at least 10 percent), has poor compatibility and is not easy to disperse, and the agglomeration phenomenon can occur, so that the polypropylene blocks a neck mold in the spinning forming process, and the polypropylene spinning forming performance is influenced.

Detailed Description

The present invention may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
The invention provides a wear-resistant master batch for a polypropylene spinning material, which comprises the following raw material components in percentage by mass:
95-98% of polypropylene, 1-3% of beta crystal form nucleating agent, 0.5-1.5% of silicone powder and 0.5-1% of dispersant.
The wear-resistant master batch for the polypropylene spinning material disclosed by the invention compounds the beta crystal form nucleating agent and the silicone powder together, an unexpected synergistic effect is achieved, and the wear resistance is improved more than that of single addition. The possible mechanism of action is: the addition of the beta crystal form nucleating agent changes the crystal form and size of the polypropylene material, and can be destroyed only by larger force, and simultaneously, the silicone powder is added to improve the surface of the polypropylene material, so that once the polypropylene material is acted by force, the silicone powder plays the first role, and when the silicone powder loses efficacy, the crystal of the polypropylene material plays a role, and under the action of the two barriers, the wear resistance of the polypropylene material can be obviously improved. In addition, the beta crystal form nucleating agent and the silicone powder cannot influence the processing performance of the material, so the spinning performance of the material cannot be influenced after the beta crystal form nucleating agent and the silicone powder are added. Meanwhile, the addition amount of the beta crystal form nucleating agent and the silicone powder is small, so that the cost can be effectively controlled and increased.
In one example, the wear-resistant master batch for the polypropylene spinning material comprises the following raw material components in percentage by mass: 95-97% of polypropylene, 2-3% of beta crystal form nucleating agent, 1-1.5% of silicone powder and 0.5-1% of dispersant. By optimizing the proportion of each component, better wear resistance can be obtained.

in one example, the dispersant is dimethyl silane. Dimethyl silane is used as a dispersing agent, so that the dispersion of the beta crystal form nucleating agent and silicone powder is facilitated, meanwhile, the wear resistance of polypropylene can be improved by dimethyl silicone oil, and the wire drawing processability of the material is not influenced. Further, the viscosity of dimethylsilane is 50cs to 350 cs. Specifically, the viscosity of dimethylsilane includes, but is not limited to, the following: 50cs, 55cs, 60cs, 65cs, 75cs, 80cs, 85cs, 100cs, 120cs, 150cs, 200cs, 250cs, 350 cs.

The invention also provides a preparation method of the wear-resistant master batch for the polypropylene spinning material, which comprises the following steps:
mixing polypropylene and a dispersing agent, then adding a beta-crystal form nucleating agent and silicone powder, and mixing again; the mixture obtained is extruded and granulated.

And (3) performance testing:
examples 1 to 3 illustrate the effect of increasing the content of nucleating agent and silicone powder on the material properties. Example 2 is used for illustrating the comparison of the effects of the nucleating agent compounded with the silicone powder with comparative example 1 and comparative example 2, examples 2 and 7 are used for illustrating the comparison of the effects of the nucleating agent with the silicone powder in different proportions, examples 2 are used for illustrating the comparison of the effects of different beta nucleating agents with examples 4 to 6, examples 2 and 8 are used for illustrating the comparison of the effects of different dispersing agents, example 2 is used for illustrating the effects of alpha and beta nucleating agents with comparative example 4, and examples 1 to 3 are compared with comparative example 3 for illustrating the influence of the addition amount of the wear-resistant material on the spinning forming. The master batches prepared in the examples and the comparative examples were added to spinning polypropylene in a mass percentage of 10%, and then the abrasion index and tensile property were measured, and the specific data are shown in table 1.
TABLE 1
As can be seen from the data in table 1, the abrasion index was reduced less in the case of example 7, which is a non-optimal ratio of the nucleating agent to the silicone powder, than in example 2, in which no silicone powder was added in comparative example 1, no nucleating agent was added in comparative example 2, and silicone powder or nucleating agent was added alone, when the nucleating agent and silicone powder were not in an optimal ratio. In the embodiments 1 to 3, as the compounding ratio of the nucleating agent and the silicone powder is increased, the abrasion index is effectively reduced, and the tensile strength of the material is improved. Example 2 and examples 4 to 6 show that aryldicarboxamide nucleating agents are the best among the different beta nucleating agents, and comparative example 3 shows that the wear index is reduced to a small extent after addition of the wear resistant material, and also affects spinning processability. It can be seen from examples 2 and 8 that the use of white oil as the dispersant results in less reduction in the abrasion index and a decrease in the tensile strength, with occasional yarn breakage. It can be seen from example 2 and comparative example 4 that the abrasion index was reduced less and the tensile strength was reduced with the use of the alpha nucleating agent.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
