Abstract

The invention discloses a hydrogenated styrene-modified dicyclopentadiene petroleum resin and a preparation method thereof, belonging to the technical field of petrochemical industry. A hydrogenated styrene-modified dicyclopentadiene petroleum resin of the present invention has a softening point of 90-130°C, a Gardner chroma of 0-1, a weight-average molecular weight of 400-1000, and a molecular weight distribution index of 1.5-2.5; A method for preparing the above-mentioned hydrogenated styrene-modified dicyclopentadiene petroleum resin of the present invention, its steps are: mixing of reaction raw materials, thermal polymerization reaction of reaction raw materials, purification and hydrogenation reaction. In the present invention, high-purity cyclopentadiene monomer and styrene monomer are used as raw materials for mixing, and by adjusting the ratio of each component and strictly controlling various process parameters of thermal polymerization reaction, the thermal polymerization process can be prevented. The occurrence of crosslinking provides favorable conditions for the subsequent hydrogenation reaction, so that the solubility, color and stability of the resin after hydrogenation are significantly improved.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, and more specifically relates to a hydrogenated styrene-modified dicyclopentadiene petroleum resin and a preparation method thereof. Background technique [0002] Petroleum resin is a kind of thermoplastic resin polymerized from C5 and C9 fractions produced in the cracking process of ethylene as the main raw material. Among them, dicyclopentadiene petroleum resin is a resin made of dicyclopentadiene in the carbon five fraction as the main raw material. It has the advantages of cheap and easy-to-obtain raw materials, high softening point, strong rigidity, and high brightness, so it is widely used in Rubber mixing, ink additives, paint coatings and adhesives, etc., but its use is limited due to its shortcomings such as deep hue, poor adhesion, and poor compatibility with elastomer materials. scope. Therefore, the modification of dicyclopentadiene petroleum resin has become the focu...
