Problems solved by technology

Since no catalyst is introduced in the production process of this method, environmental problems such as waste liquid treatment will not be caused by the removal of the catalyst. However, when this method is used for production, the thermal polymerization temperature and pressure are high. During the polymerization process, styrene It is easy to cross-link with dicyclopentadiene raw materials to generate many insoluble polymers. These polymers can only be removed by filtration, which not only produces a large amount of solid waste that is difficult to handle, but also these polymers are not easy to completely remove, thus affecting the improvement. Normal use of dicyclopentadiene petroleum resin after

Abstract

The invention discloses styrene-butadiene-styrene modified dicyclopentadiene petroleum resin and a preparation method thereof; the styrene-butadiene-styrene modified dicyclopentadiene petroleum resin comprises styrene, butadiene, cyclopentadiene monomer, an inert solvent, an initiator, a terminator, an anti-aging agent, an antioxidant, and a modifier. The preparation method comprises: first, preparing styrene-butadiene-styrene oligomer, weighing cyclopentadiene monomer and an inert solvent, adding them into a reactor, and polymerizing for 4-6 h; second, adding the styrene-butadiene-styrene oligomer, an antioxidant and a modifier, stirring and mixing well, and reacting continuously for 3-5 h; third, purifying the reaction product to obtain the modified dicyclopentadiene petroleum resin. The modified dicyclopentadiene petroleum resin has good adhesiveness and good stability, the compatibility of the petroleum resin with an elastomer material is improved greatly, the applicable range of the modified petroleum resin is widened greatly, and the petroleum resin is well worthy of application.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, in particular to a styrene-butadiene-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 genera...
