Modified regenerated polymer fiber, asphalt mixture containing fiber and preparation method thereof
The invention provides a modified regenerated polymer fiber, an asphalt mixture containing the fiber and a preparation method thereof. The preparation method of the modified regenerated polymer fibercomprises the following steps of carrying out plasma treatment on the regenerated polymer fiber, then performing grafting reaction on the treated regenerated polymer fiber and a silane coupling agentin a mixed solution of deionized water and absolute ethyl alcohol, and next, carrying out polycondensation reaction with tetraethyl orthosilicate in a mixed solution of ammonia water, deionized waterand absolute ethyl alcohol. According to the modified regenerated polymer fiber provided by the invention, the heat resistance and the toughness of the fiber are relatively high, the problem that theheat resistance of the regenerated polymer fiber is relatively poor due to the fact that the processing technology is not mature is solved, and an effective way can be provided for reuse of the wasteresources. According to the asphalt mixture prepared by the modified regenerated polymer fiber, the standard Marshall stability of the asphalt mixture at 60 DEG C reaches the requirements of petroleumasphalt specification, and the service life of an asphalt pavement can be prolonged.
本发明提供一种改性再生聚合物纤维和含有该纤维的沥青混合料及其制备方法，所述改性再生聚合物纤维的制备方法包括先将再生聚合物纤维进行等离子体处理，再将其与硅烷偶联剂于去离子水和无水乙醇的混合溶液中进行接枝反应，然后与正硅酸四乙酯于氨水、去离子水和无水乙醇的混合溶液中进行缩聚反应。本发明提供的改性再生聚合物纤维耐热性及韧性较高，解决了再生聚合物纤维因加工工艺不成熟而造成的耐热性能较差的问题，并能够为废旧资源的重新利用提供有效的途径。本发明用改性再生聚合物纤维制备得到的沥青混合料60℃标准马歇尔稳定度达到石油沥青规范要求，能够延长沥青路面的使用寿命。
