Description
技术领域technical field
本发明涉及橡胶复合材料加工领域，特别是一种铁路隧道专用橡胶止水带胶料及其制备方法。The invention relates to the field of processing rubber composite materials, in particular to a special rubber waterstop compound for railway tunnels and a preparation method thereof.
背景技术Background technique
随着我国铁路建设的快速发展，铁路隧道工程越来越多，而在许多工程建筑设计中，土建、水土结构之间都有一定的伸缩要求，所以经常留有施工缝、变形缝等缝隙，并且这些缝隙还存在防水防震等问题。橡胶止水带是利用橡胶的高弹性，在各种负荷下产生弹性变形，从而起到坚固密封，有效的解决以上漏水、渗水等问题并起到减震缓冲的作用。现有技术中传统的橡胶止水带的成本较高，并且各项性能已经难以达到中国铁路总公司2016年7月最新颁布的《铁路隧道防排水材料第2部分：止水带》的要求，需要进一步的改进。With the rapid development of my country's railway construction, there are more and more railway tunnel projects. In many engineering and architectural designs, there are certain expansion and contraction requirements between civil engineering and water and soil structures, so there are often gaps such as construction joints and deformation joints. And there are also problems such as waterproof and shockproof in these gaps. The rubber waterstop uses the high elasticity of rubber to produce elastic deformation under various loads, so as to play a strong seal, effectively solve the above problems of water leakage and seepage, and play the role of shock absorption and buffering. The cost of the traditional rubber waterstop in the prior art is relatively high, and its performance has been difficult to meet the requirements of the latest "Railway Tunnel Waterproof and Drainage Materials Part 2: Waterstop" promulgated by China Railway Corporation in July 2016. Further improvements are needed.

本发明所述铁路隧道专用橡胶止水带胶料，步骤如下：The special rubber waterstop sizing material for railway tunnels of the present invention, the steps are as follows:
1)将EPDM加入到密炼机中，在起始温度25-30℃，转速40-60转/分钟的条件下塑炼3-5分钟；再将炭黑加入到密炼机中，继续混炼5-8分钟，然后将混炼后的母胶排出。1) Add EPDM to the internal mixer, and masticate for 3-5 minutes at the initial temperature of 25-30°C and the speed of 40-60 rpm; then add carbon black to the internal mixer and continue mixing Refining for 5-8 minutes, then discharge the masterbatch after mixing.
(2)调整开炼机的辊距，加入母胶，然后加入氧化锌和硬脂酸，左右分别切割翻胶2～3次，加入防老剂，左右分别切割翻胶4～5次，加入碳酸钙和增塑剂，左右分别切割翻胶6～9次，加入促进剂，左右分别切割翻胶2～3次，加入硫化剂，左右分别切割翻胶2～3次，最后再经薄通打三角包6～8次。(2) Adjust the roller distance of the open mill, add masterbatch, then add zinc oxide and stearic acid, cut and turn the glue 2 to 3 times on the left and right, add anti-aging agent, cut and turn the glue on the left and right 4 to 5 times, add carbonic acid Calcium and plasticizer, cut and turn the glue 6 to 9 times on the left and right, add accelerator, cut and turn the glue on the left and right 2 to 3 times, add vulcanizing agent, cut and turn the glue on the left and right 2 to 3 times, and finally beat through thinner Triangular bag 6-8 times.
本发明的优异效果是：The excellent effects of the present invention are:
生胶体系中，我们选择了不饱和度很低的EPDM，从而赋予了胶料优秀的耐碱性和耐老化性能。In the raw rubber system, we chose EPDM with a very low degree of unsaturation, which endows the rubber with excellent alkali resistance and aging resistance.
硫化体系中，采用半有效硫化体系，使硫化胶既具有适量的多硫键，又有适量的单、双硫键，从而既提高了硫化胶的力学性能，又改善了硫化胶的抗热氧老化性能；半有效硫化体系使混炼胶无硫化返原现象，适合高温短时间硫化，提高了生产中的硫化效率，并且此种硫化体系使混炼胶的硫化均匀性好，硫化胶的压缩永久变形小；另外，促进剂的选择上我们采用了促进剂CZ促进剂TT并用，这种方式不仅可以提高混炼胶的硫化速度和硫化度，从而提高硫化胶的力学性能，而且可以延长胶料的焦烧时间，保证了加工安全性。In the vulcanization system, a semi-effective vulcanization system is adopted, so that the vulcanizate has both an appropriate amount of polysulfide bonds and an appropriate amount of single and disulfide bonds, which not only improves the mechanical properties of the vulcanized rubber, but also improves the thermal and oxygen resistance of the vulcanized rubber. Aging performance; the semi-effective vulcanization system makes the mixed rubber no vulcanization back to the original phenomenon, suitable for high temperature and short-term vulcanization, which improves the vulcanization efficiency in production, and this vulcanization system makes the vulcanization uniformity of the mixed rubber good, and the compression of the vulcanized rubber The permanent deformation is small; in addition, in the selection of the accelerator, we use the accelerator CZ and accelerator TT together. This method can not only increase the vulcanization speed and degree of vulcanization of the mixed rubber, thereby improving the mechanical properties of the vulcanized rubber, but also prolong the life of the rubber. The scorch time of the material is shortened to ensure the safety of processing.
防老体系中，选择三种防老剂并用，防老剂RD不易喷霜，可以防护条件苛刻的热氧老化；防老剂4010NA在胶料中易分散，对于臭氧老化，热氧老化皆有优良的防护性能；而石蜡的使用既可以从硫化胶内部迁移至表面，形成一层不易穿透的薄膜屏障，从而提高硫化胶的耐碱性和耐臭氧老化性能，又可以在胶料中起到增塑作用，改善混炼胶的加工性能，提高硫化胶的耐寒性。In the anti-aging system, choose three anti-aging agents and use them together. The anti-aging agent RD is not easy to bloom, and can protect against thermal and oxygen aging under harsh conditions; the anti-aging agent 4010NA is easy to disperse in the rubber compound, and has excellent protection performance against ozone aging and thermal oxygen aging. ; and the use of paraffin can not only migrate from the inside of the vulcanizate to the surface, forming a film barrier that is not easy to penetrate, thereby improving the alkali resistance and ozone aging resistance of the vulcanizate, but also can play a plasticizing role in the rubber compound , improve the processing performance of the compound rubber, and improve the cold resistance of the vulcanized rubber.
补强填充体系中，我们向胶料中填充了大量的炭黑和碳酸钙，在获得硫化胶较高的力学性能的同时，又最大程度的降低了生产成本。In the reinforced filling system, we filled a large amount of carbon black and calcium carbonate into the rubber compound, which not only obtains higher mechanical properties of the vulcanized rubber, but also reduces the production cost to the greatest extent.
增塑体系中，我们选择使用石蜡油，其与EPDM相容性较好，喷霜少，可以减弱聚合物分子链间作用力，从而降低硬度，提高硫化胶的扯断伸长率，使硫化胶具有优异的低温性能；另外，石蜡油还可以改善胶料中大量补强填充剂的分散性，从而提高了补强效果。In the plasticizing system, we choose to use paraffin oil, which has better compatibility with EPDM, less blooming, and can weaken the force between polymer molecular chains, thereby reducing hardness, increasing the elongation at break of vulcanized rubber, and making vulcanization The rubber has excellent low-temperature performance; in addition, paraffin oil can also improve the dispersion of a large number of reinforcing fillers in the rubber, thereby improving the reinforcing effect.
综上所述，本发明通过各种配合剂的配合，极大地降低了止水带胶料的生产成本，胶料有较好的加工性能，且制品力学性能优异，具有很好的耐碱性和抗老化性能。To sum up, the present invention greatly reduces the production cost of the rubber material for waterstops through the combination of various compounding agents. The rubber material has better processing performance, and the product has excellent mechanical properties and good alkali resistance. and anti-aging properties.
