Abstract

The invention discloses styrene modified dicyclopentadiene petroleum resin and a preparing method thereof and belongs to the technical field of petrochemical industry. The styrene modified dicyclopentadiene petroleum resin has a softening point 90 DEG C to 130 DEG C, Gardner color scale 4 to 5, weight-average molecular weight 400 to 1000, and molecular weight distribution index 1.5 to 2.5. The preparing method includes the steps of mixing of reaction materials, thermal polymerization reaction of the reaction materials, and purification of the reaction materials. The high-purity cyclopentadiene monomer and the styrene monomer are mixed; by adjusting the ratio of the components and strictly controlling various process parameters of thermal polymerization reaction, cross-linking in the thermal polarization process can be prevented, and the performances, such as solubility, color scale and compatibility with elastomers, of the styrene modified dicyclopentadiene petroleum resin are evidently improved.

Description

technical field [0001] The invention belongs to the field of petrochemical technology, and more specifically relates to a 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 focus of general attentio...
