Petroleum resin has a wide range of uses, and it has good mutual solubility with natural rubber, and can increase viscosity and soften. It is usually used together with other resins, and it can also be used as a modifier. The petroleum resin is a petroleum-derived thermoplastic, highly aromatic hydrocarbon, non-reactive hydrocarbon resin. It has the characteristics of low acid value, good miscibility, water resistance, ethanol resistance and chemical resistance, chemical stability to acid, and good viscosity and thermal stability. This article gives an example of the classification of petroleum resin use.
Petroleum resin use:
Paint: Petroleum resin is used to make a variety of paints and road marking paints. It is blended with a dry oil to make a varnish. It can improve the alkali resistance and impact resistance of varnish. Used in the production of primers to improve temperature resistance and water resistance. Doing mid-range paint not only saves 10% vegetable oil, but also improves the gloss, water resistance and acid and alkali resistance of the paint film.
Rubber: Petroleum resin is used as a rubber additive to replace the traditional coumarone resin, which can increase the viscosity and improve the mixing and extrusion performance. A petroleum resin with a low softening point can be used as a rubber plasticizer, and a high softening point can be used to enhance Liu. Light-colored petroleum resin is suitable for color rubber, and dark resin is suitable for black rubber.
Ink: Petroleum resin is suitable for the manufacture of various color offset printing inks and common inks. As a connecting agent, it can replace calcium-based rosin, which not only improves the brightness, drying speed and printing quality of the ink, but also reduces the cost.
Binder: Petroleum resin is used as a compounding agent to mix with natural rubber in a solvent to produce a pressure-sensitive adhesive, which has low reactivity under heating conditions and can maintain viscosity. Petroleum resin for ink, mainly high softening point c9 petroleum resin, dcpd resin. The addition of petroleum resin to the ink can achieve the effects of color development, quick drying, brightening, and improved printing performance.
Petroleum resin use: petroleum resin is mainly used in the coating industry. For example, petroleum resin emulsion is used for reinforcement synthesis mainly in the coating industry. For example, petroleum resin emulsion is used as reinforced synthetic latex paint, and light petroleum resin is used to manufacture oil varnish to improve. Gloss and adhesion; a resin with a low softening point is used as a plasticizer for rubber, a softening point is high to increase the hardness of synthetic rubber, and it is also used to manufacture water-resistant corrugated paper. It is composed of chlorinated paraffin surfactants and other architectural coatings; it is also widely used in printing inks, paints and adhesives, as raw materials for oilfield additives.
