随着我国工业化技术水平的不断提高，作为传动带的同步带质量水平要求越来越高。江苏港达带业有限公司为了提升同步带的质量水平，采取了新技术和新材料及新工艺等措施。通过青岛橡胶研究所、南京机电职业技术学校等单位技术合作，针对同步带在使用过程中出现的问题，在同步带骨架材料、胶料配方、胶料混炼工艺、成型工艺上进行改善，试验效果显示，提升了同步带动态性能，延长了同步带的试验寿命，也在实际使用中取得了比较好的效果。

With the continuous improvement of technical level of industrialization in China, as a synchronous belt of the belt are increasingly demanding quality levels. Jiangsu port of tape industry co., LTD. In order to improve the quality of synchronous belt, adopted new technology and new materials and new technology. By Qingdao rubber research institute, nanjing electromechanical vocational and technical schools and other units and technical cooperation, in view of the synchronous belt the problem in use process, and the synchronous belt skeleton materials, rubber, rubber formula to improve on the mixing process, molding process and test results show that improve the dynamic performance of synchronous belt and prolong the life of the synchronous belt test, and achieved good effect in actual use.

一、同步带胶料主体材料并用JPN电气化学公司产品PW40。

A synchronous belt rubber, the main body of material and JPN PW40 electrical chemical company products.

原来同步带胶料配方中主体材料氯丁橡胶全部采用国产CR322,由于国产胶在工艺性和质量稳定性上与进口橡胶有一定的差距,工艺上的差距会造成混炼胶料性能不均匀,质量不稳定会造成产品质量的波动。为了改善产品质量不稳定这样的情况，采用进口橡胶同国产橡胶并用的方法，来提高国产橡胶在工艺性和质量稳定性上的不足。

Original synchronous belt neoprene rubber formulation main body material all adopt domestic CR322, because the domestic rubber on the manufacturability and quality stability and import rubber has a certain gap, mixing rubber technology gap will cause uneven performance, the quality is not stable will cause fluctuations in product quality. In order to improve the product quality unstable situation, using the method of import rubber with domestic rubber and to improve the quality of domestic rubber in the manufacturability and the lack of stability.

二、改善同步带骨架材料。

Second, improve the synchronous belt skeleton material.

加强型同步带的骨架材料是衡量同步带动态性能和质量水平的指标，一般同步带生产厂家都采用玻璃纤维线绳，国产的玻璃纤维线绳产品质量较国外同类产品质量有一定差距：动态粘合性能低、强力较小(约为进口产品的1／2)、断裂伸长率较大、表面粗糙(有明显的粒状胶疙瘩)且直径公差较大。目前，英国NGF公司、德国米勒公司、JPNporcher公司生产的同步带用玻璃纤维线绳质量上乘，根据性价比港达带业采用上述公司生产的玻璃纤维线绳代替国产玻璃纤维线绳，改善gangda同步带动态性能。

Reinforced skeleton of synchronous belt material is measured by synchronous belt dynamic performance and quality indicators, generally synchronous belt manufacturers are using glass fiber cord, made of glass fibre cord product quality than similar foreign products quality has a certain gap: dynamic low adhesive performance, powerful smaller (about 1/2 of imported products), large elongation at break, surface roughness (has obvious granular gel bumps) and the larger diameter tolerance. At present, the British model NGF company, Germany miller, JPNporcher production of synchronous belt with glass fiber cord are superior in quality, according to the ratio of the port to take use of the company production of glass fiber cord instead of domestic glass fibre cord, improve the dynamic performance gangda synchronous belt.

三、在同步带胶料配方中添加助硫化体系

Three, is added in the synchronous belt rubber formula helps the vulcanization system

在胶料配方中原来硫化体系用金属氧化物加DM(1份)和NA-22(0.5份)，这样的硫化体系对同步带胶料性能技术要求来说,硫化程度不够，抗老化性能不高。有时硫化程度不稳定时会降低胶料的老化性能，生产出的同步带产品在实际使用过程中常常会出现产品出现带齿磨损，胶料断裂等使用寿命降低的现象。为了解决这个问题,港达带业在原来的配方基础上增加助硫化体系，添加抗硫化还原剂提高胶料硫化程度和抗硫化还原性能，这样提升了gangda同步带动态性能及稳定性。

Originally in the rubber formula using metal oxide vulcanization system with DM (1) and NA - 22 (0.5), the vulcanization system of technical requirements for the performance of synchronous belt material, degree of cure is not enough, anti-aging performance is not high. Sometimes the degree of cure instability will reduce the aging properties of rubber, produce product of synchronous belt in actual use process products often occur with tooth wear and fracture reduce the service life of phenomenon such as rubber. In order to solve this problem, the port to take industry on the basis of the original formula to increase help vulcanization system, adding sulfide reducing agent resistance increase the degree of rubber vulcanization and reversion resistance, this improved gangda synchronous belt dynamic performance and stability.

四、改善同步带胶料动态粘合性能。

Fourth, improve the synchronous belt dynamic rubber adhesive performance.

原来同步带产品在实际使用过程中会出现帆布和线绳脱层现象，为了加强芯线绳的动态粘合性能,把动态粘合性能不好的古马隆树脂去掉，添加粘合附胶性能和动态粘合性能比较好的粘合树脂。这样保证了橡胶胶料与线绳和帆布的粘合性能,又能提高胶料的动态粘合能力。

Original synchronous belt products will appear in the process of actual use of canvas and cord delaminating phenomenon, in order to strengthen the dynamic adhesion performance of wire rope, remove the bad dynamic adhesive performance of coumarone resin, adding glue with adhesive performance and the dynamic and good adhesive resin adhesive performance. This ensures the rubber adhesive performance of rubber and cord and canvas, and can improve the dynamic rubber adhesive ability.

五、改善同步带的抗屈挠疲劳体系。

Five, the improvement of synchronous belt system of flexible fatigue resistance.

原来同步带产品的实际使用过程中出现过胶料断裂的现象，其屈挠疲劳性能不理想,为了加强胶料和产品的抗屈挠疲劳性能,首先就生热高的炭黑N330换成疲劳性能好，生热低的N550。添加能提高屈挠疲劳性能的橡胶助剂HG-90，加入能提高胶料屈挠疲劳的动态性能较好的防老剂H-71(1份），同时加入产品JC-069纤维状铝硅纳米材料,这种材料不仅能提高橡胶的模量,而且生热低，抗撕裂好，耐屈挠疲劳性能显著，用量可以达到5份。

Synchronous belt products appeared in the process of the actual use of original rubber fracture phenomenon, its flexible fatigue performance is not ideal, in order to strengthen the rubber and product flexible fatigue resistance, high heat production in the first place of carbon black N330 into fatigue performance is good, low heat generating N550. Added can improve the fatigue properties of flexible rubber additives HG - 90, to join can improve flexible rubber fatigue stabilizer with better dynamic properties of H - 71 (1), at the same time to join JC - 069 fibrous aluminum silicon nanometer materials, the material can not only improve the modulus of rubber, and gave birth to low heat, tearing resistance, resistance to flexion bending fatigue performance significantly, dosage can achieve five copies.

六、在同步带配方中添加耐磨剂。

Six, wear-resisting agent is added in the synchronous belt formula.

耐磨剂JTH-315是通用型聚四氟乙烯(PTFE)超微粉经特殊工艺加工而成的低分子量微粉。为了提高同步带的耐磨性能，在胶料配方中增加耐磨体系，添加耐磨剂JTH-315和抗撕裂树脂HR-801.这两种助剂相互配合，即提高了胶料的耐磨性能，又改善了胶料的工艺性能。

Wear-resisting agent JTH - 315 is a universal polytetrafluoroethylene (PTFE) superfine powder by the special process of low molecular weight micro powder. In order to improve wear resistance of synchronous belt, increase the wear resistant system in the rubber formula, add wear-resisting agent JTH HR - 801-315 and tensile resin. These two kinds of additives to cooperate with each other, namely to improve the wear resistance of the rubber, and improved the processing properties of the rubber.

七、优化混炼胶和同步带成型工艺。

Seven, optimization of mixing rubber and synchronous belt molding process.

同步带胶料混炼胶工艺原来采用一段混炼，氯丁橡胶极易粘辊和焦烧，会造成胶料性能不均匀，导致同步带产品性能不稳定，出现产品在使用过程中的齿跟断裂等现象。采用胶料二段混炼工艺，胶料性能和工艺得到提升，产品质量水平和稳定性得到提高。

Synchronous belt rubber mixing rubber process using a mixed, neoprene glue roller and charred extremely easily, cause rubber performance is uneven, lead to synchronous belt product performance is not stable, a product in the process of using the phenomenon such as teeth with fracture. 2 of rubber mixing process, sizing performance and technology promotion, product quality and stability was improved.

同步带成型工艺原来没有停放时间，成型好的带坯直接放入硫化罐硫化。这样成型过程中所使用的溶剂没有完全挥发，胶料由于成型过程中运动没有恢复过程的时间，会导致同步带产品质量水平的不稳定性。

Synchronous belt molding process was no parking time, forming a good strip directly into vulcanizing pot sulfide. So that the solvent used in the process of forming not volatilize, rubber because of the movement in the process of forming no recovery time, will lead to the instability of synchronous belt product quality level.

八、增加张力调整同步带节线长度

Eight, increase tension adjustment of synchronous belt pitch line length

由于加强型同步带，港达带业采用了进口玻璃纤维线，拉力强度从400牛顿左右提高到800牛顿以上，所以在成型过程中将成型机张力加大了20%左右，这样能够保证港达同步带节线长度控制在国标以内更小范围。

Due to enhanced synchronous belt, the port to take industry adopted imported glass fiber yarn, the tensile strength increased from about 400 Newton to more than 800 Newton, so in molding process, molding machine tension increased by about 20%, it can ensure the port of synchronous belt pitch line length control in the national standard within a small range.

结束语：在同步带骨架材料采用进口玻璃纤维线绳，提升同步带的动态性能和质量水平；胶料设计配方中优化主体材料，通过采用进口氯丁橡胶和国产氯丁橡胶并用，提升了同步带胶料主体材料使用的稳定性能和质量水平；通过在同步带胶料配方硫化体系中添加助硫化体系，提高胶料硫化程度和抗硫化还原性能；通过改善胶料配方中的粘合体系，加强同步带帆布和强力材料线绳的附胶程度和动态粘合性能；通过改善胶料配方设计中的补强体系和添加抗屈挠疲劳体系，提升胶料在同步带传动运转过程中的耐屈挠疲劳能力；添加耐磨剂降低同步带传动过程中的生热，增强其耐磨性能；优化胶料混炼工艺和同步带成型工艺，提升产品质量水平的稳定性能，增加张力调整同步带节线长度。采用以上措施很好的提升了同步带的使用寿命，取得了非常好的使用效果。
