Modified fiber as well as preparation method and application thereof
The invention relates to the technical field of composite materials, in particular to a modified fiber and a preparation method and application thereof.The modified fiber comprises a fiber matrix, a hydrophilic layer and a mineralized surface layer, the fiber matrix is coated with the hydrophilic layer, the hydrophilic layer is coated with the mineralized surface layer, and the mineralized surface layer contains silicate and silicon dioxide and is in an amorphous and/or microcrystalline form; the hydrophilic layer serving as a middle layer is beneficial to improving the combination degree with the other two layers and improving the overall structural stability of the modified fiber, and the mineralized surface layer belongs to an inorganic mineralized layer and can improve the compatibility of the modified fiber and a concrete material and promote interpenetration. The modified fiber is used in a concrete material, so that the mechanical strength, durability and microbial erosion resistance can be further improved. The preparation method comprises the following steps: performing hydrophilic modification treatment on the surface of a fiber matrix, and forming a hydrophilic layer on the surface of the fiber matrix to obtain the hydrophilic fiber; a silicate raw material is subjected to deposition treatment on the surfaces of the hydrophilic fibers to form a mineralized surface layer wrapping the hydrophilic fibers.
本申请涉及复合材料技术领域，尤其涉及一种改性纤维及其制备方法与应用，改性纤维包括纤维基体、亲水层和矿化表层，亲水层包覆纤维基体，矿化表层包覆亲水层，矿化表层含有硅酸盐和二氧化硅且呈无定形和/或微晶形态，亲水层作为中间层有利于提高与另外两层的结合程度，提高改性纤维整体的结构稳定性，矿化表层属于无机矿化层，可以提高改性纤维与混凝土材料的相容性，促进相互渗透，改性纤维用于混凝土材料中可以进一步提高力学强度、耐久性和抗微生物侵蚀能力。制备方法包括在纤维基体的表面进行亲水改性处理，在纤维基体的表面形成亲水层，得到亲水纤维；将硅酸盐原料在亲水纤维表面进行沉积处理，形成包覆亲水纤维的矿化表层。
