| 摘要: |
| 为使涤纶织物应用范围更广，更耐磨，本文制备了一种有机硅树脂基纳米硼化钛碳化钛复合涂层，通过正交实验法得到最佳的涂层方案，并尝试将其应用于涤纶织物，以改善涤纶织物的表面结构，进而实现涤纶织物表面优异的耐磨性能.为测试涂层对涤纶织物性能的影响, 采用泰伯式耐磨仪、液滴形状分析仪、电子织物强力机、扫描电子显微镜(SEM)研究了涂层织物的耐磨性能、疏水性能、物理机械性能和磨损织物的表面微观形态.研究表明：当有机硅树脂与无水乙醇质量比为75: 25，含量(质量分数)为93%；超分散剂含量为1.5%；乙醇增稠剂含量为1.5%；纳米硼化钛和碳化钛质量比为2: 1，含量为4%时，所得涂层溶液应用于涤纶织物后会形成一层包覆层，耐磨性能最优.对于涂覆量为15 g/m2的涤纶，拉伸断裂强力由573.92 N提高到620.48 N，顶破强力由652.34 N提高到790.07 N，撕裂强力由9.87 N降低到5.78 N，疏水性能有较大提高，接触角可达到120°以上. |

| Abstract: |
| Polyester fabric has a wide range of applications, but it cannot meet the high requirement for wear resistance in some fields, so it is necessary to modify polyester fabric to improve its wear resistance and consequently widen its application range. To this end, a kind of silicone resin based nano TiB2-TiC composite coating was studied. The optimal coating scheme was obtained by orthogonal experiment and applied to polyester fabric to improve its surface structure, so as to achieve excellent wear resistance. Then the effect of coating modification on the properties of the polyester fabric was tested. The wear-resisting property, hydrophobic property, physical and mechanical property, and surface microscopic morphology of coated fabric were studied by Taber type abrasion tester, DSA100 droplet shape analyzer, HD026N electronic fabric strength machine, and S-570 scanning electron microscope (SEM) of Hitachi. The experimental results show that when the mass ratio of silicone resin and anhydrous ethanol was 75: 25 and their mass percentage was 93%, when the super dispersing agent mass percentage was 1.5%, when the ethanol thickening agent mass percentage was 1.5%, and when the mass ratio of TiB2 and TiC was 1: 2 and their mass percentage was 4%, the polyester fabric coated with the obtained solution formed a coating membrane with optimal wear resistance. For polyester fabric with a coating amount of 15 g/m2, the tensile breaking strength increased from 573.92 N to 620.48 N, the bursting strength increased from 652.34 N to 790.07 N, and the tear strength decreased from 9.87 N to 5.78 N. In addition, the hydrophobic properties of polyester fabric were greatly improved, and the contact angle was able to reach 120° or more. |
