Description
技术领域technical field
本发明涉及一种橡胶胶套，具体涉及一种用于传动带硫化用的橡胶胶套。The invention relates to a rubber rubber sleeve, in particular to a rubber rubber sleeve used for vulcanization of transmission belts.
背景技术Background technique
在传动带的生产过程中，胶套用于套在传动带的硫化模具外，具有保证传动带硫化压力、防止其高温膨胀的作用；胶套的质量和性能会直接影响传动带的性能。In the production process of the transmission belt, the rubber sleeve is used to cover the vulcanization mold of the transmission belt, which can ensure the vulcanization pressure of the transmission belt and prevent its high temperature expansion; the quality and performance of the rubber sleeve will directly affect the performance of the transmission belt.
由于胶套需要长期的在高温且潮湿的环境下使用，且使用过程中会长时间的承受内外壁压力差带来的应力。因此，胶套在使用过程中容易发生表面的热氧老化、受应力作用引起的永久变形；甚至在长期的使用过程中发生橡胶分子链的降解。Because the rubber sleeve needs to be used in a high-temperature and humid environment for a long time, and it will bear the stress caused by the pressure difference between the inner and outer walls for a long time during use. Therefore, the rubber sleeve is prone to surface thermo-oxidative aging and permanent deformation caused by stress during use; even the degradation of rubber molecular chains occurs during long-term use.
由于丁基橡胶具有较低的不饱和度，其异丁烯键具有较高的惰性，现有技术中常用丁基橡胶优良的耐热性和耐老化性来制备硫化胶套，但丁基橡胶加工性能较差，与其它橡胶的相容性和粘合性差，且硫化时间长，生产成本较高。现有技术中也有使用EPDM来制备硫化胶套的技术，虽然可以通过配合体系和硫化体系的优化来使其达到一定的效果降低了制品的成本，但EPDM本身结构特点造成的力学性能差、热收缩大的问题难以得到根本解决，产品质量和寿命难以得到保证。Because butyl rubber has a low degree of unsaturation and its isobutylene bond has high inertness, butyl rubber is commonly used in the prior art to prepare vulcanized rubber sleeves due to its excellent heat resistance and aging resistance, but the processing performance of butyl rubber Poor, poor compatibility and adhesion with other rubber, and long vulcanization time, high production cost. In the prior art, there is also a technology of using EPDM to prepare vulcanized rubber sleeves. Although the optimization of the matching system and vulcanization system can achieve a certain effect and reduce the cost of the product, the structural characteristics of EPDM itself cause poor mechanical properties, thermal The problem of large shrinkage is difficult to be fundamentally solved, and product quality and life are difficult to be guaranteed.
发明内容Contents of the invention
本发明的目的在于提供传动带用的橡胶胶套，所述橡胶硫化胶套具有耐热氧老化、高温永久变形小、高挺性、加工性能好等诸多优点。The object of the present invention is to provide a rubber rubber sleeve for a transmission belt. The rubber vulcanized rubber sleeve has many advantages such as resistance to heat and oxygen aging, small permanent deformation at high temperature, high stiffness, and good processing performance.
本发明通过如下的技术方案来实现：The present invention is realized through following technical scheme:
一种传动带用橡胶硫化胶套，由以下重量份数的原料制成：95重量份的溴化丁基橡胶、5重量份的氯丁橡胶、30-60重量份的补强剂，1-5重量份的均匀剂、1-5重量份的增粘树脂、5-10重量份的硫化酚醛树脂、1-3重量份的微晶蜡、1-3重量份的防老剂、1-3重量份的促进剂、0.2-1重量份的硬脂酸、0.5-2重量份的氧化镁、5重量份的氧化锌。A rubber vulcanized rubber sleeve for a transmission belt is made of the following raw materials in parts by weight: 95 parts by weight of brominated butyl rubber, 5 parts by weight of neoprene rubber, 30-60 parts by weight of reinforcing agent, 1-5 parts by weight The leveling agent of parts by weight, the tackifying resin of 1-5 parts by weight, the sulfurized phenolic resin of 5-10 parts by weight, the microcrystalline wax of 1-3 parts by weight, the antioxidant of 1-3 parts by weight, the anti-aging agent of 1-3 parts by weight accelerator, 0.2-1 parts by weight of stearic acid, 0.5-2 parts by weight of magnesium oxide, and 5 parts by weight of zinc oxide.
本发明提供的橡胶硫化胶套采用溴化丁基橡胶作为主要组分，溴化丁基橡胶具备优异密封性、高减震性、低渗透性的同时，由于活泼溴原子的引入，增加了交联反应的类型，具有优异硫化速率的同时也可以更好地与其它橡胶进行共硫化，有效改善现有技术中丁基橡胶硫化性能差的问题；同时溴原子的引入也提高了与其它橡胶具有更好的相容性和粘接性，提高了制品的均匀性，耐热性能大幅的提高。The rubber vulcanized rubber sleeve provided by the present invention adopts bromobutyl rubber as the main component. While bromobutyl rubber has excellent sealing performance, high shock absorption and low permeability, due to the introduction of active bromine atoms, it increases the The type of joint reaction, which has an excellent vulcanization rate, can also be better co-vulcanized with other rubbers, effectively improving the problem of poor vulcanization performance of butyl rubber in the prior art; at the same time, the introduction of bromine atoms also improves the properties of other rubbers. Better compatibility and adhesion, improve the uniformity of the product, and greatly improve the heat resistance.
此外，本发明中的溴化丁基橡胶采用酚醛树脂硫化体系进行硫化，采用该硫化体系硫化的溴化丁基橡胶形成的交联键以高键能的C-C和C-O键为主，该硫化体系给予溴化丁基橡胶较好的耐热、耐蒸汽和耐永久变形的性能；同时采用与溴化丁基橡胶具有较高相容性的氯丁橡胶作为卤素给予体，在提高酚醛树脂硫化体系硫化效率的同时，将氯丁橡胶优异的耐热和耐老化性能引入胶套的同时，并在硫化过程中形成互穿交联网络，提高了橡胶内部分子链间的结合性，在大幅改善了酚醛树脂硫化体系的硫化效果，同时提高了胶套的硫化特性和物理机械性能。相对与现有技术中加入氯化亚锡、氯化铁、二苯基溴代甲烷等卤化物来催化酚醛树脂硫化反应，本发明解决了酚醛树脂硫化体系中常用的卤化物具有腐蚀性，用量多易腐蚀制品的缺点。In addition, the brominated butyl rubber in the present invention is vulcanized by a phenolic resin vulcanization system, and the crosslinks formed by the brominated butyl rubber vulcanized by this vulcanization system are mainly C-C and C-O bonds with high bond energy. Give bromobutyl rubber better heat resistance, steam resistance and permanent deformation resistance; at the same time, neoprene rubber with high compatibility with bromobutyl rubber is used as halogen donor to improve the vulcanization efficiency of phenolic resin vulcanization system At the same time, the excellent heat resistance and aging resistance of chloroprene rubber are introduced into the rubber sleeve, and an interpenetrating cross-linked network is formed during the vulcanization process, which improves the bonding between molecular chains inside the rubber and greatly improves the performance of phenolic resin. The vulcanization effect of the vulcanization system improves the vulcanization characteristics and physical and mechanical properties of the rubber sleeve at the same time. Compared with the addition of stannous chloride, ferric chloride, diphenylbromomethane and other halides in the prior art to catalyze the vulcanization reaction of phenolic resin, the present invention solves the problem that the halides commonly used in the phenolic resin vulcanization system are corrosive, and the dosage The disadvantages of many corrosive products.
通过在橡胶硫化胶套中加入微晶蜡可以提高制品的耐老化性能，减少胶套在使用过程中形成的裂纹。By adding microcrystalline wax to the rubber vulcanized rubber sleeve, the aging resistance of the product can be improved, and the cracks formed during the use of the rubber sleeve can be reduced.
优选的，所述增粘树脂为SP1068树脂、硫化酚醛树脂为SP1044树脂。Preferably, the tackifying resin is SP1068 resin, and the vulcanized phenolic resin is SP1044 resin.
优选的，所述补强剂为炭黑N220、炭黑N330或炭黑N375。Preferably, the reinforcing agent is carbon black N220, carbon black N330 or carbon black N375.
优选的，所述防老剂为防老剂2246、防老剂1010、或防老剂BHT。Preferably, the anti-aging agent is anti-aging agent 2246, anti-aging agent 1010, or anti-aging agent BHT.
优选的，所述均匀剂为均匀剂D95。Preferably, the leveling agent is leveling agent D95.
优选的，还包括1-10重量份的云母粉。Preferably, 1-10 parts by weight of mica powder is also included.
通过在体系中加入云母粉，可以利用其径厚比高，阻隔效率高的特点，进一步提高硫化胶套的气密性。By adding mica powder into the system, the airtightness of the vulcanized rubber sleeve can be further improved by taking advantage of its high diameter-thickness ratio and high barrier efficiency.
本发明还提供了上述橡胶胶套的制备方法，具体包括如下步骤：The present invention also provides the preparation method of above-mentioned rubber rubber sleeve, specifically comprises the following steps:

At the same time as halogen, the performance of neoprene rubber is introduced into the vulcanized rubber sleeve, and an intertransfer cross-linked network is formed during the vulcanization process, while reducing the cost of the product, and it also solves the need to add high pollution and corrosion in the vulcanization of phenolic resin in the prior art The technical problem of non-toxic halogen additives effectively improves the air tightness, aging resistance, permanent deformation resistance and thermo-oxidative aging performance of the vulcanized rubber sleeve, greatly improves the service life of the vulcanized rubber sleeve, and reduces the use cost of the product.
