Abstract

The invention provides a preparation method of petroleum resin through mixing aliphatic hydrocarbon resins and aromatic hydrocarbon resins, belonging to the technical field of organic synthesis. The invention adopts C-5 resin and C-9 resin as the raw materials. The invention is characterized in that the preparation process is carried out according to the following steps: (1) C-5 resin and C-9 resin are adopted as the raw materials, which are reacted in a normal pressure reactor for more than or equal to two hours to produce fatty resins-mixture compounded by aromatic hydrocarbon resins, wherein, the reaction temperature is controlled at 180 to 200 DEG C; (2) rubber asphalt is added in the system for more than or equal to two hours to produce the finished products, wherein, the reaction temperature is controlled at 180 to 200 DEG C. The petroleum resin prepared with the method of the invention is capable of improving the mixing uniformity of rubbers of different polarity and viscosity, reducing the mixing time, improving the mobility of the rubber materials, improving the stretching strength and the physical and mechanical properties of the rubber materials, and fundamentally overcoming the influence of processing various additives on the stretching strength; the tear strength is increased and the wear loss is reduced. The product is of low price and is suitable for promotion.

Description

technical field [0001] The invention belongs to the technical field of organic synthesis, and in particular relates to a preparation technology of petroleum resin. Background technique [0002] In the tire industry, leveling agents are generally used for mixing rubbers of different polarities and viscosities. In the prior art, a leveling agent 40MSF is commonly used in tire tread rubber. Homogenizer 40MSF is an imported raw material, and currently there is no domestic enterprise that can produce it. Homogenizer 40MSF has obvious effects on shortening mixing time, reducing mixing energy consumption, improving carbon black dispersion effect, and improving rubber mixing uniformity, but its disadvantage is that it is expensive. With the rise of raw material prices, the high price of leveling agent 40MSF is obviously too much burden on domestic small and medium-sized enterprises. Contents of the invention [0003] The object of the present invention is to provide a preparati...
