Description
Technical field
The utility model relates to the chemical industry equipment field, is specially a kind of cohesion butadiene-styrene rubber polymerization reaction kettle.
Background technology
Along with China's rapid development of economy, living standards of the people improve constantly, and the domestic automobile industrial development is rapid, and auto industry has become one of pillar industry of China at present, country continues to improve the developing of automobile industry level, cultivates the consumption market based on the private consumption.China's automobile industry development planning is put into effect, and the policy of a series of stimulation automobile consumptions that match with it or is soon put into effect, and these all are conducive to guarantee increase in the year that keep about 10% in Chinese automobile market.The development of automobile industry will be conducive to increase domestic elastomeric demand.Butadiene-styrene rubber (SBR) is a kind of general purpose synthetic rubber that output is the highest in the world, consumption figure is maximum at present, wherein solution polymerized butadiene styrene rubber (SSBR) accounts for 7.01% of world's synthetic rubber total productive capacity, SSBR is in stage of steady development, and growth rate is very fast, is SBR development priority from now on.Solution polymerized butadiene styrene rubber (SSBR) is that butadiene and styrene adopt organolithium to cause anionic polymerisation in varsol and the copolymer that makes.Because advantages such as that it has is wear-resisting, cold-resistant, heat generation is low, color and luster good, ash content is few, purity is high and curingprocess rate is fast, very fast in developed country's development in recent years, along with popularizing of tire meridianization, especially the development of novel energy-conserving radial, tire is had higher requirement with glue, not only require the rubber strength height, anti-slippery is good, also requires flow resistance low.Solution polymerized butadiene styrene rubber has had the combination property that anti-slippery is good and resistance to rolling is low concurrently, it is the suitable sizing material of all-year tire, can satisfy tire at a high speed, safe, energy-conservation, comfortable requirement, tire drag with its manufacturing is low, wet-sliding resistant performance is good, anti-wear performance is good and living heat is low, has become to make radial-ply tyre and the requisite important source material of high-performance tire.The contents of ethylene of at present homemade SSBR is lower, performance indications such as wet-sliding resistant performance and resistance to rolling and steady quality performance and imported product still have gap, its main cause is the backwardness on technology and the equipment, usually contain alkynes, amine and other heavy ends such as present polymerisation with butadiene, if be directly used in the butadiene-styrene rubber polymerization, the conversion ratio of influence reaction and the quality of product.
