Petroleum resin is widely used and has good compatibility with natural rubber.
Petroleum resins are thermoplastic, highly aromatic, non-reactive hydrocarbon resins derived from petroleum.
It has the characteristics of low acid value, good miscibility, water resistance, ethanol resistance and chemical resistance, etc.
This paper gives an example of classification of petroleum resin.
Petroleum resin application:
Paint: petroleum resin is used to make various paints and road marking paints.
It is mixed with drying oil to make varnish.
It can improve the alkali and impact resistance of varnish.
Used in primer production to improve temperature resistance and water resistance.
Do intermediate paint not only save 10% vegetable oil, still can improve paint film burnish, water resistance and acid-base.
Rubber: petroleum resin is used as rubber additive, which can replace traditional gumalong resin, and can increase viscosity, improve mixing and extrusion performance.
The petroleum resin with low softening point can be used as rubber plasticizer, and the one with high softening point can be used as reinforcing material.
Light color petroleum resin is suitable for colored rubber and dark color resin is suitable for black rubber.
Ink: petroleum resin is suitable for manufacturing various color offset printing inks and common inks, as a linker, and can replace calcium rosin, not only can improve the ink brightness, drying speed and printing quality, but also reduce the cost.
Binder: petroleum resin as a coordination agent and natural rubber in the solvent mixed to manufacture pressure-sensitive adhesive, under heating conditions, with low reactivity, and can maintain viscosity.
Ink with petroleum resin, mainly high softening point c9 petroleum resin, DCPD resin.
Ink with petroleum resin can play a display, fast drying, brightening effect, improve printing performance.
Other USES of petroleum resin: petroleum resin is mainly used in the coating industry, such as petroleum resin emulsion used to enhance the synthesis of mainly used in the coating industry, such as petroleum resin emulsion used to enhance the synthesis of latex paint, light color petroleum resin used in the manufacture of oil varnish, in order to improve the luster and adhesion;
The resin with low softening point is used as plasticizer for rubber, and the resin with high softening point is used to improve the hardness of synthetic rubber.
Also used for manufacturing water - resistant corrugated paper.
It and chlorinated paraffin surfactant composition of building coatings;
It is also widely used in printing inks, paints and viscose, as well as raw materials for oil field auxiliaries.
