Production of petroleum resin

Petroleum resin is a petroleum by-product of pyrolysis of C5 and C9 fractions. It is a thermoplastic resin manufactured by preprocessed, aggregated, distillation and other processes. Petroleum resin is not a polymer, but oligomers with molecular weight of 300-3000. According to the raw material, petroleum resin are divided into aliphatic resin (C5), cycloaliphatic resin (DCPD), aromatic resins (C9), aromatic/aliphatic resin (C5/C9) and hydrogenated petroleum resin. Hydrogenation of C5 petroleum resin, C9 hydrogenated petroleum resin.

Petroleum resin can be used in the production of paint and road marking paint. In the production of primers, it increases temperature resistance and water resistance. Mid-range Paint saves not only 10% vegetable oil, but also improves the coating film luster, water resistance and resistance to acid and alkaline.

Petroleum resin as ingredients mixed with natural rubber in a solvent to make pressure-sensitive adhesives, it has low reactivity, and can maintain the viscosity under heating. Petroleum resins for printing ink are mainly high softening point C9 petroleum resin and DCPD resins. Add petroleum resin to ink has the effect of quick-drying, brightening, improve printing performance and so on.

Petroleum resin mainly used in paint industrial, for example, petroleum resin emulsion is used as enhanced synthesis latex paint; light petroleum resin is used for manufacturing oily varnish to improve gloss and adhesion; low softening points of resin is used for rubber of plasticizer, and high softening points resin is used to improve hardness of synthetic rubber. Petroleum resin and chlorinated surfactants can compose of architectural coatings, it is also widely used in printing inks, paints and adhesives, oil additives and other raw materials.

Because of the raw materials and technical constraints, part of the ethylene production capacity lags behind States can not produce petroleum resin by themselves. They rely heavily on imports to meet its domestic traffic paint and adhesives industry needs. Main imports national are India, Thailand, Malaysia, Indonesia, Viet Nam, etc, accounted for half around of China petroleum resin export volume. In additional, Europe, Japan and Korea are also main country of China petroleum resin export. After the fast development of United States page rock gas, petroleum resin of production raw materials cracking C5 and C9 production reduced, as a result, imports petroleum resin from China became important channel.
