Embodiment Construction

[0018] The present invention will be further described below through specific embodiments.

[0019] Embodiments 1-10 carry out the preparation of hydrogenated petroleum resin according to the following steps: the reaction raw material is the material rich in piperylene, and its main composition is shown in Table 1, and the process conditions of each step are shown in Table 2 (step 1), table 3 (step 1) and Table 4 (step 2), after the reaction finishes, weigh and analyze each index (softening point, molecular weight distribution and bromine value etc.) of resin sample, the results are shown in Table 5, and the miscibility with other polymers is shown in Table 6 . Adopt gel chromatography to measure resin product molecular weight distribution index (M w / M n ), using the ring and ball method GB / 2294 to analyze the softening point, and using the iodometric method (SWB2301-62) to analyze the bromine value.

Abstract

The invention discloses a modified piperylene hydrogenated petroleum resin and a preparation method thereof. In the present invention, firstly, the imidazole compound is used as the modifier, and the modifier is added in the polymerization process of piperylene to obtain the piperylene modified petroleum resin; then the piperylene modified petroleum resin is prepared by catalytic hydrogenation to obtain the improved Piperylene Hydrogenated Petroleum Resin. The modified piperylene hydrogenated petroleum resin obtained by the invention has high thermal stability, good compatibility with elastomers (such as SIS and SBS, etc.) in hot melt adhesives, and relatively light color.

Description

technical field [0001] The invention relates to a modified piperylene hydrogenated petroleum resin and a preparation method thereof, belonging to the technical field of petrochemical industry. Background technique [0002] With the continuous development of various fields, the quality requirements for petroleum resins are 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 good stability. [0003] Due to the disadvantages of high brittleness, lack of polar groups on the molecule, and deep color of the C5 resin, in order to broaden the application field of the resin, the existing technology improves the performance of the petroleum resin by adding a modifier to copolymerize, such as Chinese patent application CN2014104942...
