Petroleum resin is named because it is derived from petroleum derivatives. It has low acid value, good miscibility, water resistance, ethanol resistance and chemical resistance. It is chemically stable to acid and alkali, and has good viscosity adjustment and thermal stability. specialty. Petroleum resins are generally not used alone, but as accelerators, regulators, modifiers and other resins.

Application

A. Paint: The paint mainly uses high softening point C9 petroleum resin, DCPD resin, and C5/C9 copolymer resin. Adding petroleum resin to the paint can increase the glossiness of the paint and improve the adhesion, hardness, acid and alkali resistance of the paint film. B. Rubber: Rubber mainly uses low softening point C5 petroleum resin, C5/C9 copolymer resin and DCPD resin. This kind of resin has good mutual solubility with natural rubber particles and has no major influence on the rubber vulcanization process. The addition of petroleum resin to the rubber can increase viscosity, strengthen and soften the rubber. In particular, the addition of C5/C9 copolymer resin can not only increase the adhesion between the rubber particles, but also improve the adhesion between the rubber particles and the cord, which is suitable for high-demand rubber products such as radial tires. C. Adhesive industry: Petroleum resin has good adhesion. Adding petroleum resin to adhesives and pressure-sensitive tapes can improve the adhesion, acid resistance, alkali resistance and water resistance of the adhesive, and Can effectively reduce production costs. D. Ink industry: Petroleum resin for ink, mainly high softening point C9 petroleum resin and DCPD resin. The addition of petroleum resin to the ink can achieve the effects of color development, quick drying, brightening, and improving printing performance. E. Others: The resin has a certain degree of unsaturation and can be used as a paper sizing agent, plastic modifier, etc.
