中文摘要:
      目的 制备基于纳米CaCO3的涂布型防滑纸,并对其性能进行研究。方法 首先采用硬脂酸钠对纳米CaCO3进行有机化改性,然后将水性聚氨酯、甘油和改性后的纳米CaCO3充分共混,冷却后均匀涂布于纸张表面。采用红外光谱对纳米CaCO3进行表征,并对涂料粘度和涂布纸的静摩擦因数进行测定。结果 通过红外光谱分析可知,硬脂酸钠与纳米CaCO3得到有效结合。通过单因素试验确定了制备防滑纸的最佳工艺条件,即纳米CaCO3的质量分数为4%、甘油的质量分数为2%、干燥温度为70 ℃,在此工艺条件下纸张的静摩擦因数可达到0.835,最大倾斜角为39.86°。结论 制备的纳米CaCO3涂布型防滑纸不仅摩擦性能良好,而且力学性能较佳,可用于制备运输包装用防滑衬垫和防滑托盘。
英文摘要:
      The work aims to prepare the coated antis-skid paper based on nano-CaCO3 and study its performance. Firstly, nano-CaCO3 was organically modified by sodium stearate. Then, the waterborne polyurethane, glycerol and modified nano-CaCO3 were fully mixed and then evenly coated on the paper surface after cooling. The nano-CaCO3 was characterized by infrared spectroscopy, and the coating viscosity and static friction coefficient of the coated paper were measured. According to the infrared spectroscopic analysis, the sodium stearate was effectively bound with nano-CaCO3. The optimal technological condition was determined by the single-factor test when the mass fractions of nano-CaCO3 and glycerol and the drying temperature were 4%, 2% and 70 ℃, respectively. Under such condition, the static friction coefficient of paper could reach 0.835 and the maximum inclination angle was 39.86°. The coated anti-skid paper of nano-CaCO3 prepared not only has a good friction performance, but also a preferable mechanical property; and it can be used for the preparation of anti-skid pad and anti-skid tray for transport packaging.
