Composite fiber modified calcium silicate as well as preparation method and application thereof
The invention discloses composite fiber modified calcium silicate as well as a preparation method and application of the composite fiber modified calcium silicate. The composite fiber modified calcium silicate is prepared from the following raw material components: 40 to 45 parts of fly ash based porous light calcium silicate, 1 to 2 parts of acid liquor with the concentration of 0.1 to 0.5 M, 10 to 12 parts of imidazolium ionic liquid, 15 to 20 parts of brucite nanofiber, 0.2 to 1.0 part of unsaturated alkoxy silane and a proper amount of deionized water. According to the invention, the surface of the composite fiber modified calcium silicate can be fully combined and wound with brucite nanofibers through modified grafting of components, the porosity is reduced, the surface polarity is increased, when the composite fiber modified calcium silicate is applied to papermaking, the whiteness and tightness of paper can be enhanced, meanwhile, the tensile strength is also greatly improved, and the printing is firm and durable.
本发明公开了一种复合纤维改性硅酸钙及其制备方法与应用，按重量份数计，所述复合纤维改性硅酸钙的制备原料包含如下组分：粉煤灰基多孔轻质硅酸钙40‑45份、浓度为0.1‑0.5M的酸液1‑2份、咪唑类离子液体10‑12份、水镁石纳米纤维15‑20份、不饱和烷氧基硅烷0.2‑1.0份和适量去离子水。在本发明中，所述复合纤维改性硅酸钙表面通过组分的改性接枝，能够充分地与水镁石纳米纤维结合缠绕，孔隙率降低，表面极性增加，应用于造纸时，能够实现纸张白度和紧度的增强，同时抗张强度也大幅提升，印刷牢固，经久耐用。
