Bamboo pulp cellulosic fiber/hydrated magnesium silicate based composite and preparation method thereof
The invention discloses a bamboo pulp cellulosic fiber/hydrated magnesium silicate based composite and a preparation method thereof. The bamboo pulp cellulosic fiber/hydrated magnesium silicate basedcomposite comprises, by weight, 4-16 parts of bamboo pulp cellulosic fiber, 33.6-55 parts of magnesium oxide, and 37.8-60 parts of silica ash. According to the bamboo pulp cellulosic fiber/hydrated magnesium silicate based composite, the bamboo pulp cellulosic fiber serves as a reinforced phase of the magnesium silicate based composite, and the bending strength and fracture toughness of the composite are improved; meanwhile, the pH value of a magnesium silicate matrix is lower than that of Portland cement, the influence of the alkalinity on fiber degradation can be reduced, the fiber in the composite can achieve the long-term reinforcement effect, and the durability is improved. Moreover, magnesium oxide is rich in reserves and excellent in performance. The bamboo pulp fiber is short in growth cycle, high in yield, green and renewable. The bamboo pulp cellulosic fiber/hydrated magnesium silicate based composite and the preparation method thereof provide a new approach to utilization ofbamboo fiber and magnesium oxide. The prepared bamboo pulp cellulosic fiber/hydrated magnesium silicate based composite has the advantages of high strength, high fracture toughness, light weight, lowalkalinity and the like, and follow the concept of sustainable development of a building material.
本发明公开了一种竹浆纤维素纤维/水化硅酸镁基复合材料及其制备方法，由以下重量份原料制成：竹浆纤维素纤维4‑16份、氧化镁33.6‑55份、硅灰37.8‑60份。本发明以竹浆纤维素纤维作为硅酸镁基复合材料的增强相，提高了复合材料的抗弯强度和断裂韧性，同时硅酸镁基体的pH值较硅酸盐水泥基体低，可以降低碱度对纤维劣化的影响，使纤维在复合材料中能起到更为长久地增强效果，改善了耐久性。再者，氧化镁储量丰富、自身性能优越，竹浆纤维生长周期短、产量高、绿色可再生，本发明为竹纤维和氧化镁的利用提供了新的途径，且制备出的竹浆纤维素纤维/硅酸镁基复合材料具有高强度、高断裂韧性、轻质、低碱度等优点，遵循了建筑材料可持续发展的理念。
