Embodiment 1

[0013] Embodiment 1, the preparation method of this modified coumarone resin is carried out according to the following steps: the first step, 1# oil slurry is added in the polymerization kettle; the second step, the unsaturated hydrocarbon is added in the polymerization kettle and stirred evenly , the amount of unsaturated hydrocarbon added is 1 / 1000 to 5 / 1000 of the mass of 1# oil slurry; the third step is to raise the temperature of the material in the polymerization kettle to 180°C to 220°C within 1 hour to 2 hours, and control the temperature of the polymerization kettle The polymerization reaction is carried out under the pressure of -70Kpa to -95Kpa, and the modified coumarone resin is obtained after the polymerization reaction for 3 hours to 4 hours.

Embodiment 2

[0014] Embodiment 2, the preparation method of this modified coumarone resin is carried out according to the following steps: the first step, the 1# oil slurry is added in the polymerization kettle; the second step, the unsaturated hydrocarbon is added in the polymerization kettle and stirred evenly , the amount of unsaturated hydrocarbon added is 1 / 1000 or 5 / 1000 of the mass of 1# oil slurry; the third step is to raise the temperature of the material in the polymerization kettle to 180°C or 220°C within 1 hour or 2 hours, and control the temperature of the polymerization kettle The polymerization reaction is carried out under the pressure of -70Kpa or -95Kpa, and the modified coumarone resin is obtained after the polymerization reaction for 3 hours or 4 hours.

Embodiment 3

[0015] Embodiment 3, the difference with embodiment 1 and embodiment 2 is: in the second step, in the polymerization tank, add unsaturated hydrocarbon and polymerization inhibitor successively and stir evenly, the add-on of unsaturated hydrocarbon is 1# oil slurry 002%。 1 / 1000 to 5 / 1000 of the quality, the addition of the inhibitor is 0.0002% to 0.002% of the total mass of unsaturated hydrocarbons and inhibitors.

Abstract

The invention relates to the technical field of resin preparation, and particularly relates to a preparation method for modified coumarone resin. The preparation method for modified coumarone resin comprises the following steps of: step 1, adding 1# oil slurry in a polymerizer; step 2, adding unsaturated hydrocarbons in the polymerizer and uniformly stirring, wherein the added amount of the unsaturated hydrocarbons is 1/1000 to 5/1000 of the mass of the 1# oil slurry; and step 3, heating the materials in the polymerizer to 180-220 DEG C in 1-2 hours, controlling the pressure in the polymerizer to be minus 70-minus 95 Kpa, and performing polymerization reaction for 3-4 hours to obtain the modified coumarone resin. According to the invention, the modified coumarone resin is obtained by sequentially adding the 1# oil slurry, the unsaturated hydrocarbons and a polymerization inhibitor in the polymerizer; and the modified coumarone resin obtained by the preparation method disclosed by the invention has the characteristics of being high in viscosity, strong in adhesive force, tension-resistant and wear-resistant.

Description

technical field [0001] The invention relates to the technical field of resin preparation, and relates to a preparation method of modified coumarone resin. Background technique [0002] Coumarone resin is also called indene resin, benzofuran-indene resin, coumarone resin, oxyindene resin, commonly known as coal tar resin. Coumarone resin is obtained by catalyzed polymerization reaction of ethylene tar and carbon nine as raw materials. The appearance of the product is yellow, brown, and black block solid. It has good compatibility, water resistance, acid and alkali resistance, rust resistance and electrical properties. . However, the existing coumarone resins have the problems of poor viscosity, adhesion, tensile resistance and wear resistance. Contents of the invention [0003] The invention provides a preparation method of modified coumarone resin, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the problems of poor viscosity,...
