Inorganic whiskers as a new type of reinforced material, with a high-strength, heat-resistant, corrosion resistant, conductive, insulating, absorbing, flame retardant, and many other special benefits and features. Whisker is the transition state of the fibers and particles, and a shape similar to the short fibers. Whiskers dual characteristics of both fibers and particles as a filler, can be greatly improved added, without affecting the strength and some whiskers as filler paper can impart some special functions. This thesis explores the effect of different dispersants on inorganic whisker filler dispersion. Experiments using sodium dodecyl benzene sulfonate (SDBS), sodium dodecyl sodium sulfate (SDS), polyoxyethylene alkylphenol ether (OP-10), sodium hexametaphosphate (SHMP) four kinds of dispersing agent, The results showed that OP-10 as a dispersing agent to improve the dispersibility of the inorganic whiskers are better. The paper using several different inorganic whiskers as filler paper, and with traditional fillers to do the comparison, research paper performance improvement in filler paper application process and give the paper a new feature. By calcium carbonate whisker ordinary calcium carbonate, tetrapod-shaped zinc oxide whisker particles of powdered zinc oxide and basic magnesium sulfate whisker natural water periclase comparative study, the results show that: calcium carbonate whiskers as filler paper instead ordinary calcium carbonate are feasible. Calcium carbonate whiskers have a higher retention rate than traditional calcium carbonate, and to improve the physical strength of the paper is some help. Tensile strength based on the SEM, SEM-EDAX and zero range and short-range data, a model to explain the mechanism of paper strength. The study also found that, add a certain amount of tetrapod-shaped zinc oxide whisker (T-ZnOw) has little effect on the strength properties of the paper. The T-ZnOw without the use of retention agents to obtain a higher retention rate. The T-ZnOw add help sheet the improvement of the whiteness and opacity. Add T-ZnOw antibacterial paper with broad-spectrum antimicrobial activity, its antibacterial efficiency than add ZnO antibacterial paper. Meanwhile, the basic magnesium sulfate whisker than natural brucite having a better flame-retardant effect, when the plus fill an amount of 25%, the oxygen index is greater than 25%, to achieve the flame retardancy level. When adding the filling amount exceeds 25%, a greater negative impact on the paper is the physical strength. Test the basic magnesium sulfate whisker under different pH and temperature solubility in water. SEM, SEM-EDAX and TGA analysis reveals the basic magnesium sulfate whisker morphology, distribution and flame retardant mechanism in the paper.
