Embodiment 1
[0038] A kind of preparation method of hydrogenated styrene-modified dicyclopentadiene petroleum resin of the present embodiment, its step is:
[0039] Step 1, mixing of reaction raw materials:
[0040] Mix high-purity cyclopentadiene monomer, styrene monomer and inert solvent to form a mixed solution. The mass parts of the three components in the mixed solution are: 30 parts of inert solvent, 30 parts of high-purity cyclopentadiene 60 parts of monomer, 25 parts of styrene monomer. The high-purity cyclopentadiene monomer in this embodiment is based on commercially available dicyclopentadiene industrial products with a mass percentage of about 80% as a raw material, and it is added to an atmospheric rectification tower with a theoretical plate number of 15 In the kettle, and the temperature of the tower kettle is heated to 200°C, and the fraction of 41-44°C collected from the top of the tower at a reflux ratio of 2. The finally obtained high-purity cyclopentadiene monomer inc...
Embodiment 2
[0049] A kind of preparation method of hydrogenated styrene-modified dicyclopentadiene petroleum resin of the present embodiment, its step is:
[0050] Step 1, mixing of reaction raw materials:
[0051] Mix high-purity cyclopentadiene monomer, styrene-based monomer and inert solvent to form a mixed solution. The mass parts of the three components in the mixed solution are respectively: 46 parts of inert solvent, 46 parts of high-purity cyclopentadiene 45 parts of monomers, 18 parts of styrene monomers. The high-purity cyclopentadiene monomer in this example is based on the commercially available C9 industrial product as a raw material, which is added to an atmospheric rectification column with a theoretical plate number of 15, and the application number is CN200510025319 prepared by the process in the Chinese patent. The finally obtained high-purity cyclopentadiene monomer includes the following components in mass percentage: 99.2% cyclopentadiene, 0.71% dicyclopentadiene, a...
Embodiment 3
[0059] A kind of preparation method of hydrogenated styrene-modified dicyclopentadiene petroleum resin of the present embodiment, its step is:
[0060] Step 1, mixing of reaction raw materials:
[0061] Mix high-purity cyclopentadiene monomer, styrene-based monomer and inert solvent to form a mixed solution. The mass parts of the three components in the mixed solution are: 60 parts of inert solvent, 60 parts of high-purity cyclopentadiene 40 parts of monomers, 30 parts of styrene monomers. The high-purity cyclopentadiene monomer in this example is based on the commercially available C10 industrial product as raw material, which is added to an atmospheric rectification column with a theoretical plate number of 15, and the application number is CN200510025319 prepared by the process in the Chinese patent. The finally obtained high-purity cyclopentadiene monomer includes the following components in mass percentage: 99.2% cyclopentadiene, 0.76% dicyclopentadiene, and 0.04% other...
