preparation example Construction

[0033] The preparation method of the excellent petroleum resin of anti-aging performance of the present invention, comprises the following steps:

[0034] 1) obtaining a petroleum resin polymer solution by cationic polymerization and water washing to remove the catalyst;

[0035] 2) Take the polymerization liquid in step 1), and add antioxidant A of 0.1-2‰ of the weight of the petroleum resin polymerization liquid, after mixing evenly, remove the solvent oil with a temperature range of 42-180°C; wherein, the antioxidant Agent A is selected from one or more of liquid 1010, liquid B7402N, liquid B7125, and liquid 530C. Liquid B7402N and liquid B7125 were purchased from Tianjin Lianlong New Materials Co., Ltd., and liquid 530C was purchased from Shanghai Yejian Keao High Temperature Materials Co., Ltd.

[0036] 3) Continue to increase the temperature to 230-260°C, and pass steam into the rectification kettle. The temperature of the steam is controlled at 220-240°C, and the steam...

Embodiment 1

[0041] Add 0.1g of liquid antioxidant 530C to 1000g of C5 petroleum resin polymerization solution, mix the above polymerization solution and antioxidant evenly, add it to a round bottom flask for distillation, and collect solvent oil with a temperature range of 42-180°C. Continue to rise to 240°C and feed 220°C steam to control the steam pressure to 1.4MPa. Stop steaming until no oligomers are produced, pour out 400g of molten petroleum resin, and add 1.2g of solid antioxidant 1010 to it, stir evenly and let it cool. Obtain C5 resin Gardner color number 2.9#, blast at 180°C for 4 hours, C5 petroleum resin color number 6.1#, continue to extend the time to 8 hours to obtain C5 petroleum resin Gardner color number 9.0#.

Embodiment 2

[0043] Add 1.2g of liquid antioxidant 530C to 1000g of C5 petroleum resin polymerization solution, mix the above polymerization solution and antioxidant evenly, add it to a round bottom flask for distillation, and collect solvent oil with a temperature range of 42-180°C. Continue to rise to 230 DEG C and feed 230 DEG C of steam to control steam pressure 1.5MPa, stop passing steam to no oligomer output, pour out molten petroleum resin 390g, and add 0.4g solid antioxidant to it (1010 / 626= 2:1) Stir evenly and let it cool down to obtain C5 resin Gardner color number 2.6#, blast at 180°C for 4 hours, C5 petroleum resin color number 6.0#, and continue to prolong the time to obtain C5 petroleum resin Gardner color number 8.9#.

Abstract

The invention discloses petroleum resin with excellent anti-aging performance and a preparation method thereof, and belongs to the technical field of petroleum resin research. The petroleum resin comprises a petroleum resin polymerization solution, an antioxidant A and an antioxidant B. The preparation method of the petroleum resin comprises the following steps: 1) removing a catalyst by cationicpolymerization and water washing to obtain a petroleum resin polymerization solution; 2) adding an antioxidant A into the polymerization solution, uniformly performing mixing, and removing the solventat 42-180 DEG C; 3) performing heating to 230-260 DEG C, and introducing steam into the rectification kettle to obtain petroleum resin in a molten state; and 4) adding an antioxidant B into the obtained petroleum resin, fully stirring and cooling to obtain the petroleum resin with the softening point of 60-130 DEG C and the Gardner color number of 2-3.2, thereby obviously improving the thermal aging color number and aging resistance of the resin and being beneficial to further ensuring the usability of the resin.

Description

technical field [0001] The invention relates to the technical field of petroleum resin research, and more specifically relates to a petroleum resin with excellent aging resistance and a preparation method thereof. Background technique [0002] With the development of the petroleum industry, petroleum resin has also been developed rapidly, and its production technology has gradually matured and has a certain production scale. Especially in recent years, with the continuous improvement of production technology and fierce market competition, new varieties of petroleum resins continue to appear, and the application fields are also continuously expanded. It has developed into a multi-variety, multi-brand, multi-purpose functional synthetic resin. Among them, weather-resistant resins with high softening points, low-viscosity resins, copolymer resins, and light-colored high-grade petroleum resins are the fastest-growing, because of their good miscibility, good thermal stability, an...
