Description
技术领域technical field
本发明属于化工领域,具体涉及一种既耐磨又生热低的全钢胎面胶料配方及其制备方法。The invention belongs to the field of chemical industry, and in particular relates to an all-steel tread compound formula with both wear resistance and low heat generation and a preparation method thereof.
技术背景technical background
对于全钢胎面胶配方设计要求具有高定伸、高强度、高弹性、低生热、中等硬度,满足全钢轮胎耐磨、滚阻低、耐刺的性能。For the design of the all-steel tread rubber formula, it is required to have high constant elongation, high strength, high elasticity, low heat generation, and medium hardness to meet the performance of all-steel tires with wear resistance, low rolling resistance, and puncture resistance.
当然轮胎使用条件不同,用途不同,一般分导向轮和驱动轮轮胎,在硬度和定伸应力方面作适当调整,如好路面(一般为条形花纹)硬度和定伸要高些,差些的路面(一般越野型花纹)而相对要低一些,但由于载重子午胎胎冠刚性较大,在硬度方面要保持较高,同时弹性要高,抗刺扎性要好,以保护带束层钢丝避免受腐触,同时胎面胶要考虑它的综合使用性能。Of course, tires have different service conditions and different uses. Generally, they are divided into guide wheel and driving wheel tires, and the hardness and constant elongation stress should be adjusted appropriately. The road surface (general off-road pattern) is relatively lower, but due to the high rigidity of the crown of the radial truck tire, the hardness must be kept high, and at the same time, the elasticity must be high and the puncture resistance is better to protect the belt steel wire from Corrosion, while the tread rubber should consider its comprehensive performance.
配方的生胶体系通常选用100%顺式1,4-聚异戊二烯橡胶,但也有个别掺用20%~30%聚丁二烯橡胶的来提高胶料耐磨性能。The raw rubber system of the formula usually uses 100% cis-1,4-polyisoprene rubber, but there are also individual blends of 20% to 30% polybutadiene rubber to improve the wear resistance of the rubber.
补强体系一般选用耐磨性较高的N110系列炭黑,其中N121炭黑结构高,定伸应力高,而N115在结构上与N110相当,但比表面积略高,综合性能比N110进一步。从价格考虑N234,在综合性能方面应与N115接近。The reinforcement system generally uses N110 series carbon black with high wear resistance, among which N121 carbon black has a high structure and high modulus stress, while N115 is equivalent to N110 in structure, but its specific surface area is slightly higher, and its comprehensive performance is better than N110. Considering the price, N234 should be close to N115 in terms of overall performance.
另一特点是选用了白炭黑和硅烷偶联剂Si-69,目前白炭黑用量为15PHR左右,炭黑40~45PH R,而Si-69为1.5~2.0PHR,这种配方与工程胎耐刺扎配方类似。Another feature is the selection of silica and silane coupling agent Si-69. At present, the amount of silica is about 15PHR, carbon black is 40-45PHR, and Si-69 is 1.5-2.0PHR. This formula is similar to that of engineering tires. The puncture-resistant formula is similar.
从现代轮胎性能要求,采用白炭黑取代部分炭黑已成为趋势,其目的是为降低滚动阻力而又保持较高防滑性,同时改进胎面胶耐扎性能。但其趋势不像轿车子午胎那么明显,目前仍有许多公司并未采用白炭黑,炭黑用量在47~52份。From the performance requirements of modern tires, it has become a trend to replace part of carbon black with white carbon black. The purpose is to reduce rolling resistance while maintaining high anti-skid performance, and at the same time improve the anti-puncture performance of tread rubber. However, the trend is not as obvious as that of car radial tires. At present, there are still many companies that do not use white carbon black, and the amount of carbon black is 47-52 parts.
由于顺式1,4-聚异戊二烯橡胶具有较高撕裂强度和粘合性能,所以全钢子午线轮胎的胎面胶料配方普遍采用纯顺式1,4-聚异戊二烯橡胶的生胶体系,但纯顺式1,4-聚异戊二烯橡胶的生胶体系耐磨性能一般。Since cis-1,4-polyisoprene rubber has high tear strength and adhesive properties, pure cis-1,4-polyisoprene rubber is generally used in the tread compound formula of all-steel radial tires However, the raw rubber system of pure cis-1,4-polyisoprene rubber has average wear resistance.
同时现配方采用N234炭黑30phr+白炭黑20phr+硅烷偶联剂并用的填充体系,能够降低胶料的生热,所以现低滚阻配方采用该填充体系,但是与普通全钢子午线轮胎胎面配方相比之下耐磨性不足。At the same time, the current formula adopts the filling system of N234 carbon black 30phr + white carbon black 20phr + silane coupling agent, which can reduce the heat generation of the rubber compound, so the current low rolling resistance formula adopts this filling system, but it is different from the common all-steel radial tire tread formula In contrast, the wear resistance is insufficient.
总之两方面的原因造成了该胎面配方耐磨性不足。In short, there are two reasons for the lack of wear resistance of the tread formula.
基于上述原因,发明一种新型的全钢胎面胶料配方就显得尤为必要。Based on the above reasons, it is particularly necessary to invent a kind of novel all-steel tread compound formula.

本发明的有益效果Beneficial effects of the present invention
1、该配方采用顺式1,4-聚异戊二烯橡胶和稀土元素为催化剂生产的钕系高顺式聚丁二烯橡胶两胶并用的生胶体系,使用传统的钕系高顺式聚丁二烯橡胶能够提高胶料的耐磨性,而使用稀土元素为催化剂生产的钕系高顺式聚丁二烯橡胶比传统的钕系高顺式聚丁二烯橡胶耐磨性更好,生热相比较低,同时保证胎面胶料的耐撕裂性能。1. The formula uses cis-1,4-polyisoprene rubber and rare earth elements as catalysts to produce neodymium-based high-cis-polybutadiene rubber. The raw rubber system uses traditional neodymium-based high-cis-polybutadiene rubber. Polybutadiene rubber can improve the wear resistance of the rubber compound, and the neodymium-based high-cis-polybutadiene rubber produced using rare earth elements as a catalyst has better wear resistance than the traditional neodymium-based high-cis-polybutadiene rubber , relatively low heat generation, while ensuring the tear resistance of the tread compound.
2、同时使用V9H炭黑纯炭黑填充体系,该炭黑的比表面积比N234炭黑更大、结构比N234炭黑更高,炭黑用量增多,不使用白炭黑,补强效果好,易分散,混炼工艺易控制,既提高了胶料的耐磨性能,又不会将胶料的生热提高太多。2. At the same time, use V9H carbon black pure carbon black to fill the system. The specific surface area of this carbon black is larger than that of N234 carbon black, the structure is higher than that of N234 carbon black, and the amount of carbon black is increased. No white carbon black is used, and the reinforcing effect is good. It is easy to disperse and the mixing process is easy to control, which not only improves the wear resistance of the rubber compound, but also does not increase the heat generation of the rubber compound too much.
现全钢低滚阻胎面胶料配方采用纯顺式1,4-聚异戊二烯橡胶的生胶体系,耐磨性能比纯顺式1,4-聚异戊二烯橡胶+钕系高顺式聚丁二烯橡胶的生胶体系配方胶料耐磨性要差,与此相比,采用顺式1,4-聚异戊二烯橡胶+以稀土元素为催化剂生产的钕系高顺式聚丁二烯橡胶为生胶体系的配方耐磨性会更好,同时胶料配方的生热会更低。同时现全钢低滚阻胎面胶料配方为了得到较好的滚阻系数,配方的炭黑用量少,同时又使用了比传统全钢胎面胶料配方更多的白炭黑,这样该胶料配方炭黑的补强效果差,同时白炭黑更难分散,导致该胶料的耐磨性能差。采用高比表面积、高结构的纯炭黑填充体系,胶料补强效果好,易分散,使得胶料配方耐磨性明显改善,同时生热不会提高太多。The current all-steel low rolling resistance tread rubber formula adopts the raw rubber system of pure cis-1,4-polyisoprene rubber, and its wear resistance is better than that of pure cis-1,4-polyisoprene rubber + neodymium The raw rubber system formula of high cis polybutadiene rubber has poor wear resistance. Compared with this, the neodymium system produced with cis 1,4-polyisoprene rubber + rare earth elements as catalyst The formulation of cis-polybutadiene rubber as the raw rubber system will have better wear resistance, and the heat generation of the rubber formulation will be lower. At the same time, in order to obtain a better rolling resistance coefficient in the current all-steel low rolling resistance tread compound formula, the amount of carbon black in the formula is less, and at the same time, more silica is used than the traditional all-steel tread compound formula, so that The reinforcing effect of the carbon black in the compound formula is poor, and the silica is more difficult to disperse, resulting in poor wear resistance of the compound. The pure carbon black filling system with high specific surface area and high structure has good reinforcing effect and is easy to disperse, so that the wear resistance of the rubber formula is significantly improved, and the heat generation will not increase too much.
