高性能防静电瓦楞纸板及其影响因素的研究

High-performance Anti-static Corrugated Board and its Influence Factors

目的研制一种高性能的防静电瓦楞纸板、纸箱,并研究涂布量,运输环境的温度、相对湿度及机械摩擦对其防静电性能的影响。方法采用定量涂布的方式将防静电涂料均匀涂覆在原纸表面,通过改变涂布量研究其与纸板防静电等级的关系;通过改变环境温度、相对湿度、摩擦参数(次数和强度)来模拟研究实际运输途中温度、相对湿度及摩擦参数(振动、冲击等机械力造成的)对瓦楞纸箱防静电性能的影响。结果在研究的范围内,随着温度、相对湿度的增加,防静电纸板表面电阻率也增加,但是材料的防静电等级未发生变化,仍为导静电材料,其中相对湿度对防静电的影响较温度的影响更为明显;摩擦对防静电性能的影响比相对温湿度明显。结论温度、相对湿度及摩擦参数对瓦楞纸板的防静电性能均有不同程度的影响,但仍为静电防护型材料,能够有效保护内装物不受静电的危害。

The work aims to develop a high-performance anti-static corrugated board and carton, and study the effect of coating amount and temperature, relative humidity and mechanical friction of transport environment on its anti-static performance. The anti-static coating was uniformly coated on the surface of the base paper by means of quantitative coating. The relationship between the anti-static coating and the anti-static level of the paperboard was studied by changing the coating amount. The temperature, relative humidity and friction parameters(times and intensities) of the environment were changed for the simulation study on the effect of temperature, relative humidity and friction parameters(caused by mechanical force such as vibration and impact) on the anti-static performance of the corrugated carton during actual transportation. Within the scope of study, as the temperature and relative humidity increased, the surface resistivity of the anti-static corrugated board also increased, but the anti-static level did not change, and it was still an electrostatically conductive material, in which the relative humidity had a greater effect on the antistatic effect than the temperature. The friction had a greater effect on anti-static performance than relative humidity and temperature. Temperature, relative humidity and friction have different effects on the anti-static performance of corrugated board. However, the board is still the electrostatically protected material and can effectively protect the contents from electrostatic hazards.
