[0027] When the composite rubber is prepared by the preparation method provided by the invention, the process steps of plasticizing can be saved, and it only needs to be added before adding powder during compacting. The process has the advantages of simple process and process saving.
[0028] Pentene is a colorless, volatile, flammable liquid with a density of 0.6411, a melting point of -138°C, and a boiling point of 30°C. It is insoluble in water but soluble in ethanol. It will decompose into lower hydrocarbons at high temperature. It is used in organic synthesis and dehydrogenation to produce isoprene, which can be obtained by dehydrogenation of pentane.
[0029] Cyclopentadiene is a highly active alicyclic hydrocarbon with molecular formula C 5 h 6 , colorless liquid, melting point -97.542 ° C, boiling point 40 ° C, relative density 0.8021, exists in coal tar, easy to react with unsaturated compounds to generate a large number of cyclic compounds. Cyclopentadiene is also...
Embodiment 1
[0055] This embodiment is a kind of composite rubber, which includes the following raw materials by weight percentage: pentene 50%, cyclopentadiene 30% and dicyclopentadiene 20%.
[0056] The preparation method of the composite rubber includes the following steps: mixing pentene, cyclopentadiene and dicyclopentadiene, and performing a polymerization reaction, and obtaining the composite rubber after the reaction is completed. Wherein, the polymerization reaction temperature is 20°C.
Embodiment 2
[0058] This embodiment is a kind of composite rubber, which includes the following raw materials by weight percentage: 45% pentene, 35% cyclopentadiene and 20% dicyclopentadiene.
[0059] Wherein, the preparation method is the same as in Example 1.
