preparation example Construction

[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.

Abstract

The invention provides composite rubber as well as a preparation method and an application thereof, and relates to the rubber field. The composite rubber is prepared from the following raw materials in percentage by weight: 45%-55% of pentene, 25%-35% of cyclopentadiene and 15%-25% of dicyclopentadiene. The composite rubber can solve the technical problem of the substantial increase of shoe material cost due to high cost of existing natural rubber and styrene-butadiene rubber, and reduces the cost.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a composite rubber and its preparation method and application. Background technique [0002] The current rubber industry mainly uses natural rubber as raw material, but the supply of natural rubber is tight and the price remains high. Restricted by geographical conditions, the growth rate of my country's natural rubber production is slow. It is predicted that the annual output of natural rubber in my country can increase by more than 700,000 tons at most, which is difficult to meet the needs of the rapid development of the domestic rubber industry; however, the output of synthetic rubber will increase with the development of China's petrochemical industry. my country's annual rubber consumption ranks first in the world. In order to make up for the shortage of domestic natural rubber resources, my country has imported more than 1 million tons of natural rubber every year in the p...
