Problems solved by technology

[0005] In the preparation method of the above-mentioned alicyclic C5 petroleum resin, the technological process of C5 thermal polymerization → cationic catalytic polymerization is generally adopted, and the product is mainly composed of polycyclic ring structures similar to polydicyclopentadiene (DCPD), and lacks polar groups. , so it has poor compatibility with APAO, SBS, SEBS, NBR and other substrates
Moreover, the color of C5 petroleum resin obtained by this process is relatively dark, and its Gardner color number is usually 7~12#, which cannot be used in the field of light-colored and transparent hot-melt adhesives, and the market application is limited

Embodiment 1

[0031] In this example, the C5 raw material composition is 3.0wt% isopentene, 5.0wt% cyclopentene, 6.0wt% n-pentene, 6.0wt% isoprene, 8.0wt% cyclopentadiene, piperylene 6.0 wt%, and the rest are saturated C5-C6 alkanes such as isopentane, n-pentane, and cyclopentane.

[0032] Put the C5 raw material into the polymerization kettle R101, polymerize at a temperature of 240°C for 6 hours, and transfer the obtained polymerization liquid into the flash tank V101, and flash at a vacuum degree of -0.085MPa and a temperature of 110°C, unreacted C5 solvent is obtained at the top, and the bottom get C 10 Mixed ingredients. will get C 10The material is conveyed into the polymerization kettle R201, mixed evenly with 4-methylstyrene and xylene at a mass ratio of 1:0.2:0.7, and then reacted at 245°C for 15 hours to obtain a polymerization reaction liquid. Afterwards, the polymerization reaction solution is transported into the rectification tower T201, and rectification is carried out at ...

Embodiment 2～6

[0034] In Examples 2-6, the C5 raw material is composed of 2.0wt% isopentene, 5.0wt% cyclopentene, 6.0wt% n-pentene, 4.0wt% isoprene, 6.0wt% cyclopentadiene, and 4.0 wt% of diene, and the rest are saturated C5-C6 alkanes such as isopentane, n-pentane, and cyclopentane. The C5 raw material is polymerized at 230°C for 5 hours, enters the V101 flash tank, and flashes at a vacuum of -0.085MPa and a temperature of 105°C. Unreacted C5 solvent is obtained at the top and C at the bottom. 10 The composition of the mixed material is as follows: C 10 Component tricyclic [5.2.1.0 2,6 ]dec-8-ene content 69.6%, (1Z,5Z)-3,4-dimethyl-1,5-cyclooctadiene content 11.5%, 1-methyl-4-(prop-1-1ene -2-yl) cyclohexene content 10.4%, the rest C 15 The component content is 8.5%.

[0035] C above 10 The mixed material is mixed with different modified monomers and xylene in a mass ratio of 1:0.3:0.7 to obtain a polymerization raw material, which is reacted at a certain temperature to obtain a polymer...

Embodiment 7～10

[0039] with the same ingredient C 10 The material and styrene are mixed in different proportions to obtain the polymerization raw material, which is reacted at a high temperature of 227°C for 10 hours to obtain a petroleum resin liquid, which is then subjected to the same hydrogenation reaction conditions (temperature 230°C, pressure 14.5MPa, liquid space-time Speed ​​0.5h -1 ) to prepare hydrogenated modified C5 petroleum resin and the performance difference is as follows:

[0040]

[0041] As can be seen from the above examples, when styrene is used as the modified monomer, along with its 10 As the content of the polymerized ingredients increases, the softening point of the hydrogenated modified resin gradually decreases, the color number becomes lighter, and the aromaticity increases linearly; at the same time, the Z-average molecular weight of the resin decreases significantly, which is beneficial to the application in the field of adhesives and rubber mixing.

Description

technical field [0001] The invention belongs to the field of petroleum resins, in particular to a preparation method of hydrogenated modified C5 petroleum resins. Background technique [0002] Petroleum resin is a solid or viscous liquid medium-low relative molecular weight polymer obtained by catalyzed polymerization or free radical polymerization with the by-product C5 and C9 fractions of the ethylene plant as the main raw material. According to the monomer and molecular structure of the resin, it can be roughly divided into aromatic petroleum resin, aliphatic petroleum resin and alicyclic petroleum resin. [0003] Aliphatic petroleum resins and alicyclic petroleum resins are obtained through different C5 raw materials and polymerization processes respectively. The structure of the former is mainly linear alkanes with branched chain structure, and most of them are directly obtained by catalytic polymerization through Friedel-Crafts alkylation; The latter structure is domi...
