Petroleum resin is a kind of thermoplastic resin produced from C5 and C9 fractions by-products of petroleum cracking, through pretreatment, polymerization, distillation and other processes, which is not a polymer but an oligomer with molecular weights ranging from 300 to 3000.
Petroleum resins are divided into aliphatic resins (C5), alicyclic resins (DCPD), aromatic resins (C9), aliphatic/aromatic copolymerized resins (C5/C9), and hydrogenated petroleum resins according to the raw material.C5 Hydrogenated Petroleum Resin, C9 Hydrogenated Petroleum Resin.
Petroleum resin is a newly developed chemical product in recent years, which can be widely used in a variety of industries and fields such as rubber, adhesives, coatings, paper making, printing ink, etc., due to its advantages of low price, good miscibility, low melting point, resistance to water, ethanol and chemicals.
C9 petroleum resin refers to resinous substances made by polymerizing olefins or cycloolefins containing nine carbon atoms or copolymerizing them with aldehydes, aromatics, terpenes and other compounds.
C5 petroleum resins are gradually replacing natural resin tackifiers (rosin and terpene resins) because of their high peel bond strength, good fast tack, stable adhesive properties, moderate melt viscosity, good heat resistance, good compatibility with polymer matrices, and low price.
Paint mainly use high softening point of C9 petroleum resin, DCPD resin, C5/C9 copolymerization resin, paint to add petroleum resin can increase paint gloss, improve film adhesion, hardness, acid resistance, alkali resistance.
Petroleum resin has good adhesive property, adding petroleum resin to adhesive and pressure-sensitive adhesive tape can improve adhesive strength, acid resistance, alkali resistance and water resistance, and can effectively reduce the production cost.
Petroleum resins for inks are mainly high softening point C9 petroleum resins and DCPD resins. The addition of petroleum resin to ink can play a role in color spreading, quick drying, brightening effect, and improving printing performance.
Road signs and road marking paint, petroleum resin has good adhesion to concrete or asphalt pavement, and good abrasion resistance and water resistance, and inorganic substances have good affinity, easy to spread, good weather resistance, fast drying, high firmness, and can improve the physical and chemical properties of the layer, improve UV resistance and weather resistance. At present, petroleum resin road marking paint gradually tends to the mainstream, the demand is rising year by year.
The resin has a certain degree of unsaturation, can be used for paper gluing agent, plastic modifier and so on.
Petroleum resin is non-dangerous goods, in the process of transportation, it should be prevented from sunshine and rain; it should not be transported together with spontaneous combustion, strong oxidizing agent and strong acid.
