Description
Technical Field
The invention relates to the technical field of petroleum resin, in particular to a carbon nine petroleum resin and a preparation method thereof.
Background
Petroleum resin is solid or viscous liquid polymer with relatively low molecular weight and is prepared with C5/C9 fraction as side product of ethylene unit as main material. Monomers and molecular structures composed of resins are roughly classified into aromatic hydrocarbon petroleum resins, aliphatic petroleum resins, alicyclic petroleum resins, and the like.
The aromatic hydrocarbon petroleum resin, also called C9 petroleum resin, is obtained by polymerizing the ethylene byproduct C9 fraction as a raw material, wherein the raw material is mainly cracking C9 fraction oil of an ethylene device byproduct, which accounts for about 10% -20% of the yield of ethylene, and the fraction oil has complex components and is rich in unsaturated hydrocarbons such as styrene, methyl styrene, dicyclopentadiene, indene, methyl cyclopentadiene dimer and the like.
At present, there are two main methods for producing petroleum resins using C9 fractions: one is a cationic catalytic low-temperature polymerization method (abbreviated as a cold polymerization method), and the other is a heating-initiated radical polymerization method (abbreviated as a hot polymerization method). The thermal polymerization process of the carbon nine petroleum resin has the advantages of simple process, high conversion rate and yield, stable product performance and the like, and has the main defects that a resin product with high quality performance cannot be obtained, the hue and compatibility of the resin are generally poor, the high-end market demand cannot be met, the thermal polymerization process is generally only applied to the fields of alkyd paint, rubber mixing and the like, and the added value of the product is low.
The cold polymerization carbon nine petroleum resin is resin with certain softening point obtained through copolymerization of polyolefin component in C9 fraction under the condition of catalyst or peroxide initiator. The main polymerizable components in the C9 fraction all contain large conjugated electron cloud structures, and the main polymerizable components are easy to copolymerize with certain monomers with electrophilic groups; in addition, the aromatic ring is also an ideal electrophilic substitution reaction substrate, and polar groups are easily introduced into the aromatic ring for chemical modification. In patent CN1091751a, water-soluble C9 petroleum resin is prepared by solution radical copolymerization or radical emulsion polymerization of polar molecules such as acrylic acid, maleic anhydride, etc. and C9 distillate oil under the initiation of peroxide or azo compound. Therefore, there is an urgent need to find a new method for preparing the carbon nine petroleum resin. Accordingly, the prior art is subject to further development.

In some embodiments, the amount of catalyst used in the alkylation reaction is from 0.1% to 0.2% of the hydroxy compound and methyl styrene in the alkylation reaction.
In some embodiments, the mass fraction of the carbon nine fraction that participates in the copolymerization is 54.3%.

The above shows that the bromine number and softening point of the carbon nine petroleum resin can be influenced by the feeding proportion of the first methyl styrene, the softening point is reduced when the first methyl styrene feeding amount is increased, and the bromine number is increased; the amount of methyl styrene added for the first time is reduced, the softening point is increased, and the bromine number is reduced. The feeding ratio of the styrene to the methyl styrene can influence the softening point and the bromine number of the carbon nine petroleum resin, the styrene amount is increased and reacted relatively severely, the softening point is relatively increased, the bromine number is reduced, the styrene amount is reduced, and the softening point and the bromine number are reduced. The reaction temperature of the methyl styrene during the first feeding can influence the softening point and the bromine number of the carbon nine petroleum resin, the softening point is reduced when the temperature is increased, the bromine number is reduced, and the softening point and the bromine number are increased when the temperature is reduced.
