Abstract

The invention relates to a preparation method for a multicomponent copolymer petroleum resin. The preparation method comprises: according to a weight part ratio, adding an inert solvent, a cyclopentadiene derivative, an aliphatic conjugated diolefin, an aromatic olefin and a monoolefine into a high pressure reaction still to form a mixture liquid, replacing with nitrogen for 2-3 times, heating the mixture liquid, slowly heating to 200-280 DEG C, controlling the reaction still pressure of less than 3 MPa, under the condition, reacting for 3-20 hours, after finishing the reaction, and carrying out reduced pressure distillation to obtain the multicomponent copolymer petroleum resin. The preparation method has simple process and low cost, allows the obtained resin to have good solubility and compatibility, and is the safe and reliable preparation method for the multicomponent copolymer petroleum resin.

Description

technical field [0001] The invention belongs to the field of petrochemical industry, in particular to a multi-component copolymerized petroleum resin and a preparation method thereof. Background technique [0002] Petroleum resin is a low-molecular-weight thermoplastic resin obtained by polymerization of by-products C5 and C9 in the process of petroleum cracking as the main raw material. Petroleum resins can be divided into C5 petroleum resins according to different sources of raw materials, that is, aliphatic petroleum resins, which mainly use piperylene in the C5 fraction obtained from olefin cracking as the main raw material; C9 petroleum resins, that is, aromatic petroleum resins, It is mainly based on the aromatic olefins in the C9 fraction as the main raw material; C5 / C9 petroleum resin is a mixed resin that is polymerized after mixing C5 raw materials and C9 raw materials. Dicyclopentadiene petroleum resin is a resin made from dicyclopentadiene in the C5 fraction as ...
