摘　　要：介绍了轻型输送带的结构及其制造工艺，分析了其接头方式及覆盖层表面花纹的形状，重点从填充剂、增塑剂对PVC轻型输送带覆盖胶的力学性能、耐磨性能、拉伸强度、冲击弹性、邵尔A硬度等方面的影响进行了论述。指出棉纺行业多个工序使用的轻型输送带，其结构包括覆盖层、骨架层和底层，覆盖层表面有多种花纹，骨架层有1～3层织物之分。同时，介绍了橡胶类和树脂类两种轻型带的制造技术。添加一定量的填充剂后，覆盖胶力学性能、耐磨性能及硬度均发生变化；酯类增塑剂用量在5份时呈反增塑现象，覆盖胶拉伸强度最高，加到10份以上时拉伸强度逐渐降低；环氧大豆油的增塑效果比较明显，可用于制造符合FDA标准的环保型PVC轻型输送带。Introduction is made to the light belt regarding the structure, manufacturing process. Analysis is done to the impact of the stuffing material and plasticized material on the physical performance, abrasionresistance,tension degree, impact bounce-back and Shore A hardness of the light belt of PVC. The light belt for the textile industry has three parts, say, surface, back-bone, foundation. The surface has grains of varities. The back-bone has fabric layers from one to three. Introduction is made to the manufacturing techniques of belts of rubber and resin. Changges have taken place when some stuff is put in regarding the physical performance, abrasion resistance, and hardness. When plasticized agent is applied more than five portions,plasticization decreases yet with highest tension strength of the covering rubber. When the plasticized agent is applied more than ten portions, the tension strength begins to decrease. The epoxy soybean oil has marked plasticied reinforced effect, thus applicable for manufacturing light environment-friendly PVC belt in conformity with norm FDA.
