Problems solved by technology

The indicators to measure these three performances are mainly grip, rolling resistance, and wear, but improving one performance indicator will often lead to a decline in other performance indicators, which is the so-called tire devil's triangle.

Embodiment 1

[0050] Put 70 parts of raw material styrene, 30 parts of toluene and 50 parts of rosin with an iodine value of 183 into the autoclave. 1.1MPa. After reacting for 3 hours, the temperature was lowered to below 100°C, the reactant was poured out, and excess solvent and unreacted monomer were evaporated to obtain 108 parts of yellow resin with a softening point of 108°C.

Embodiment 2

[0052] Raw materials and solvent ratios are the same as in Example 1. Raise the reaction temperature to 200°C. After the temperature stabilizes, the pressure is at 0.3MPa. After 4 hours of reaction, the temperature is lowered to below 100°C. The reacted monomers gave 96 parts of a yellow resin having a softening point of 103°C.

Embodiment 3

[0054] The ratio of raw materials and solvents is the same as in Example 1. Raise the reaction temperature to 300°C. After the temperature stabilizes, the pressure stabilizes at 2.6MPa. After 2 hours of reaction, lower the temperature to below 100°C, pour out the reactants, and steam out excess The solvent and unreacted monomers were used to obtain 110 parts of yellow resin having a softening point of 110°C.

Abstract

The invention discloses a rosin modified C9 petroleum resin and a preparation method thereof. Rosin and C9 petroleum resin react by high temperature and high pressure polymerization to prepare the rosin modified C9 petroleum resin. The rosin modified C9 petroleum resin at least comprises the structure shown as formula (I), formula (II) and formula (III). The invention also puts forward application of the rosin modified C9 petroleum resin in rubber tyre treads. The rosin modified petroleum resin can improve the tear resistance of tyre treads, enhance the rigidity of C9 petroleum resin and the wet skid resistance of tyre treads, and has broad application prospects in the field of rubber preparation.

Description

technical field [0001] The invention relates to a C9 petroleum resin, in particular to a rosin-modified C9 petroleum resin and a preparation method and application thereof, belonging to the technical field of chemical industry. Background technique [0002] With the development of the economy and the progress of society, people have higher and higher requirements for the safety, fuel economy and durability of tires. The indicators to measure these three performances are mainly grip, rolling resistance, and wear, but improving one performance indicator will often lead to a decline in other performance indicators, which is the so-called tire devil's triangle. It is known that solution-polymerized styrene-butadiene rubber and white carbon black can be used instead of emulsion-polystyrene-butadiene-butadiene rubber and carbon black to simultaneously improve grip and reduce rolling resistance. Solution-polymerized styrene-butadiene rubber and white carbon black are the basic mate...
