摘要:为提高抗凝冰涂籵的贮存稳定性,通过 Gibbs吸附定理及 Stokes沉降数学模型分析了抗凝冰涂料的贮存稳定性
机理,提出了影响抗凝冰涂料贮存稳定性的因煮有沥青颗粒周国的乳化剂吸附量、分散液的粘度η以及沥青颗粒与
分散液之间的密度差4p,通过进一步分析认为影响抗凝冰涂料贮存稳定性的上述因索与抗凝冰剂/沥青的比值y及
抗凝冰涂井的固含量β密切相关,基于此分别研究了抗凝冰剂/沥青的比值γ及抗凝冰涂料的国含量B对抗凝冰涂料
贮存稳定性的影响规律。研究结果表明:当来用y=0.26、B=59%时,所制备的抗凝冰涂料不仅具有良好的贮存稳
定性,而且具有显著的抗凝冰效呆。

Abstract In order to improve the storage stability of anti-icing coating, by using the Gibbs adsorption
theorem and Stokes settlement mathematical model, the storage stability mechanism of anti-icing coating was
analyzed and the factors affecting the storage stability of anti-icing coating, including the emulsifier
adsorption capacity of the particles around asphalt, the viscosity n of dispersion and the density difference Ap
between asphalt particles and dispersion, were presented. By further analysis, it is found that the
abovementioned influencing factors of the storage stability of anti-icing coating are closely related to the ratio y
of anti-icing agent to asphalt and anti-icing coatings solid content B. And then the impact of y and Bon the
storage stability of anti-icing coating were studied. The results show that when y=0. 26 and =59%, the
prepared anti-icing coating not only has good storage stability but also shows remarkable anti-icing effect
