【摘要】 为了研制具有黏结性好、疏水性强以及融冰雪性好的涂层,按正交设计将偶联剂、盐化物、疏水剂加入乳化沥青中制备抑冰融雪涂层,通过黏结性试验、冰黏附力试验、疏水性能试验研究各组分对涂层性能的影响,采用矩阵分析法优化得到涂层的最佳配比,最后验证了涂层的抑冰和融雪性能。研究结果表明:偶联剂对涂层的黏结性能影响最大,偶联剂掺量的增加使涂层附着力先增大后减小,当掺量为1.0%时涂层附着力达到最大为2.18 MPa;盐化物对冰黏附力影响最大,盐化物掺量增加会显著降低冰黏附力,掺量从5%增加到14%时冰黏附力降低了60.5%;疏水剂对接触角影响最大,疏水剂掺量的增加使接触角先增大后减小,在4%掺量时接触角达到最大为87.72°;优化得到涂层的最佳配比为5%疏水剂、1.0%偶联剂和14%盐化物,具有良好的抑冰融雪效果。更多还原

【Abstract】 In order to develop a coating with good adhesion,strong hydrophobicity and good ice-snow melting properties,coupling agents,salts and hydrophobic agents are added into the emulsified asphalt to prepare ice-suppression and snow-melting coatings according to orthogonal design.The influence of each component on the performance of the coating is studied by bonding test,ice adhesion test and hydrophobic test.The optimum proportion of the coating is obtained by matrix analysis method.Finally,the icing and snowmelt performance of the coating are verified.The results show that coupling agent has the greatest influence on the adhesion of the coating.The adhesion increases first and then decreases with the increase of coupling agent content.The maximum adhesion reaches 2.18 MPa when the content of coupling agent is1.0%;salt has the greatest influence on the ice adhesion force;the ice adhesion force decreased by 60.5%when the salt content increased from 5%to 14%;hydrophobic agent has the greatest influence on contact angle;the contact angle increases firstly and then decreases with the increase of hydrophobic agent content;the maximum contact angle reaches 87.72 degree when the content of hydrophobic agent is 4%;and the optimum proportion of the coating is 5% hydrophobic agent,1.0% coupling agent and 14% salt compound which has good ice-snow melting effect.更多还原
