Problems solved by technology

However, the above-mentioned patents focus more on the laboratory preparation of the catalyst, and do not propose a specific process flow
[0005] In the current process, rubber and polyolefin resin are generally directly blended, and the obtained blend is difficult to achieve microscopic mixing, and the performance of the blend is poor

Embodiment 1

[0036] Such as figure 1 As shown, a manufacturing method of a high molecular polymer material is generated in two series reactors, with an output of 40,000 tons / year, and the weight distribution of the two reaction monomer units in the final product is 10:90.

[0037] S1, in the process described, the first reaction material consisting of monomer 1,3-butadiene and diluent is mixed with isopentane and Ziegler-Naturium composed of titanium tetrachloride and triethylaluminum The tower catalyst system (titanium / aluminum is 1:1000) enters the first reactor 1 (stirred tank reactor) together, the feed flow rate of the catalyst system is 1kg / h, the reaction temperature of the first reactor is 30°C, and the reaction pressure is 0.4Mpa, catalyst activity is 5000kg product / kg catalyst, 1,3-butadiene feed is 300kg / h, 1,3-butadiene concentration in reaction solution is 300kg1,3-butadiene / m 3 solvent. The reaction time is 72h. The 1,3-butadiene polymer accounts for 10% of the total mass ...

Embodiment 2

[0041] The operating conditions of the first reactor 1 and the second reactor 4 and the selection of materials in the stream are the same as in Example 1, and the output is also the same as 40,000 tons / year. The difference is that the different reaction polymerizations in the two reactors The monomer content is distributed among the products. In this embodiment, the distribution of butadiene units and ethylene units in the total mass of the final product is 20:80.

[0042] S1, the first reaction raw material stream: monomer 1,3-butadiene and diluent isopentane, Ziegler-Natta catalyst system (titanium / aluminum is 1 :1000) into the first reactor 1 together. The feed flow rate of the catalyst system is 1kg / h, the reaction temperature of the reactor is 30°C, the reaction pressure is 0.4Mpa, the catalyst activity is 5000kg product / kg catalyst, the feed rate of 1,3-butadiene is 300kg / h, and the reaction solution The concentration of 1,3-butadiene in is 300kg1,3-butadiene / m 3 solv...

Abstract

The invention discloses a method for producing a high molecular polymer material. The method comprises: S1. Flowing the first reaction raw material flow containing diolefins into the first reaction zone, and polymerizing under the action of a catalyst to obtain The flow of polydiene rubber; S2. The flow obtained in step S1 is passed into the second reaction zone, and the added second reaction raw material flow containing monoolefin monomer continues to undergo polymerization reaction to obtain an intermediate product flow; S3, The intermediate product stream in step S2 is melt-kneaded in the presence of a crosslinking agent to obtain the high molecular polymer material. The product of the invention is a performance thermoplastic elastomer, which has the advantages of plastic and rubber, and has good toughness, elasticity, stretchability and elongation at break.

Description

technical field [0001] The present invention relates to the field of high molecular polymerization, and furthermore, relates to a method for manufacturing high molecular polymer materials. Background technique [0002] The rubber industry is one of the important industries of polymer materials in my country. It provides many product materials for people's daily life, covering daily use, medical use, construction, machinery, transportation, electronics and other fields. In recent years, with the rapid development of the national economy, people's demand for rubber, especially high-performance rubber materials, is increasing. [0003] The development of rubber has also gone through several different stages, from the first generation of natural rubber to the second generation of ordinary synthetic rubber, and has now developed to the third generation of thermoplastic elastomers. Thermoplastic elastomer (TPE) has the physical and mechanical properties of traditional vulcanized ...
