Embodiment Construction

[0016] The present invention will be further described below through specific embodiments.

[0017] Embodiment 1~10 carries out the preparation of hydrogenated petroleum resin according to the following steps: reaction raw material is the material rich in DCPD, and its main composition is shown in Table 1, and each step process condition is shown in Table 2 (step 1), table 3 (step 1) and Table 3 (step 2). After the reaction, the resin samples were weighed and analyzed for various indicators (softening point, molecular weight distribution and bromine value, etc.). The results are shown in Table 5. The molecular weight distribution index (M) of the resin product was determined by gel chromatography w / M n ), the softening point was analyzed by the ring and ball method GB / 2294, and the bromine value was analyzed by the iodometric method (SWB2301-62).

[0018] 1) After the DCPD raw material is mixed with the organic solvent, it enters the reactor, and conducts thermal polymeriza...

Abstract

The invention discloses a modified dicyclopentadiene hydrogenated petroleum resin and a preparation method thereof. The preparation method specifically comprises: (1) carrying out a thermal polymerization reaction on dicyclopentadiene and a modifier in an organic solvent to produce a petroleum resin, wherein the modifier is acrylimidazole or N-vinylimidazole; and (2) carrying out a hydrogenation reaction on the petroleum resin obtained in the step (1) under the action of a catalyst to obtain the modified dicyclopentadiene hydrogenated petroleum resin. According to the present invention, the preparation method is simple, and the obtained modified dicyclopentadiene hydrogenated petroleum resin has characteristics of high thermal stability, good compatibility with elastomers (such as SIS, SBSand the like) in hot melt adhesives, and relatively light color.

Description

technical field [0001] The invention relates to a modified dicyclopentadiene hydrogenated petroleum resin and a preparation method thereof, belonging to the technical field of petrochemical industry. Background technique [0002] Dicyclopentadiene monomer contains active double bonds and is prone to addition reaction, which can produce a series of polymers, and its application field is very broad. Dicyclopentadiene polymer resin has disadvantages such as dark color, poor cohesion, and poor compatibility with elastomer materials, which limits its application range. With the continuous development of various fields, the quality requirements for petroleum resins are also getting higher and higher. Among them, the development of adhesives and sealants, especially transparent pressure-sensitive tapes, outdoor sealants, disposable sanitary products, medical tapes, The application of road marking paint and polyolefin modifier requires petroleum resin with light color, no odor and ...
