With the rapid development of national economy, especially the rapid development of China Petrochemical three barrels of oil, making the ethylene production capacity has been gradually increasing, pyrolysis C9 more and more, how to use this part of the resources to develop downstream products is attracting more and more people’s attention. Currently pyrolysis C9 is mainly used for the production of nine carbon aromatic petroleum resin, use of appropriate technologies nine carbon synthetic resins can be used in coatings, paints, rubber and light industry, and the residue mixed aromatics production of coatings can be used as solvent.
Petroleum resin is a pale yellow to brown (sheet) solid, softening point of 80? 140 ℃, specific gravity of 0.970? 0.975, insoluble in water, soluble in organic solvents, ethylene-based production process pyrolysis C9 byproducts as the main raw material, through the thermoplastic polymeric resin. Compatibility of the viscosity, adhesion and other types of resin, has unique advantages, has been widely used in paints, rubber, paint and other industries. It is somewhat unique performance and application performance diversity, it occupies an important position in the oil industry.

Petroleum Resin application areas:
Other applications: hot melt pressure sensitive adhesives, solvent-based pressure sensitive adhesive.
Petroleum resin performance and its role in different industries:
1、paint
Paint mainly high softening point of C9 petroleum resins, DCPD resins, C5 / C9 copolymer resin, petroleum resin can increase the added paint gloss paint, paint film adhesion, hardness, acid and alkali resistance.
2、rubber
Rubber is mainly use low softening point of C5 petroleum resin, C5 / C9 copolymerized resins and DCPD resins. Such resins and natural rubber particles have good miscibility, no major effect on the rubber vulcanization process, rubber added tackifying petroleum resin can play, reinforcement, softening. Especially C5 / C9 copolymer resin is added, not only to increase the adhesion between particles, but also can improve adhesion between the rubber and tire cord for radial tire requirements such as rubber products.
3、adhesives industry
Petroleum resin having good adhesion, petroleum resin is added and the pressure-sensitive adhesive tape can increase the adhesiveness of the adhesive, the acid resistance, alkali resistance and water resistance, and can effectively reduce the production cost.
4、ink industry
Petroleum resin ink, mainly high softening point of C9 petroleum resins, DCPD resins. Added petroleum resin ink color spreading, fast dry and brightening effects and improve printing performance and so on.
5、paint industry
Road signs and road marking paint, petroleum resin, concrete or asphalt pavement have good adhesion and abrasion resistance and water resistance, and has a good affinity for inorganic coating easy, good weather resistance, fast drying, strong high and can improve the physical and chemical properties of the layer to improve resistance to UV and weathering resistance. Currently petroleum resin paint signs gradually become mainstream, the demand rise year by year.
6、Other
Resin has certain unsaturation, it can be used to glue paper, plastics modifier.
