Embodiment 1

[0039] Mix 100 parts by weight of dehydrorosin amine, 10 parts by weight of water and 500 parts by weight of epichlorohydrin, the temperature is increased to 25°C, 0.1 part by weight of tetramethylammonium chloride is added, and the temperature is reduced to 10°C after 160 hours of reaction , And then add dropwise 100 parts by weight of sodium hydroxide aqueous solution with a content of 30% by weight of sodium hydroxide (ie 30 parts by weight of sodium hydroxide and 70 parts by weight of water), after 1 hour, add 120 parts by weight of ethyl acetate, A reaction system was formed and reacted at 50°C for 5 hours. After the reaction system was cooled to room temperature and 25°C, it was washed with 170 parts by weight of deionized water each time for 4 times, then the solvent was removed with a rotary evaporator, and vacuum dried at 50°C for 12 hours to obtain a light yellow transparent viscous liquid, which is based on The epoxy resin of dehydrorosin amine was 133.3 parts by wei...

Embodiment 2

[0045] Mix 100 parts by weight of dehydrorosinamine, 30 parts by weight of water and 600 parts by weight of epibromide, the temperature is increased to 40°C, 0.5 parts by weight of octadecyltrimethylammonium bromide is added, and after reaction for 120h Cool down to 30°C, then add 120 parts by weight of potassium hydroxide aqueous solution (ie 42 parts by weight of potassium hydroxide and 78 parts by weight of water) with a potassium hydroxide content of 35% by weight, and add chloroform after 1 hour. 200 parts by weight to form a reaction system, and continue to react at 30°C for 3 hours. After the reaction system is lowered to room temperature and 25°C, it is washed with 150 parts by weight of deionized water each time for a total of 3 times, then the solvent is removed by a rotary evaporator, and vacuum dried at 50°C for 12 hours to obtain an epoxy resin based on dehydrorosinamine The resin was 136.8 parts by weight, and the yield based on dehydroabietic amine was 97.5%.

Abstract

The invention discloses dehydroabietylamine-based epoxy resin shown as a formula I. The epoxy resin has a large-size hydrophenanthrene ring, high chain segment rigidity after being cured, and high mechanical property and thermal property. The invention also discloses a preparation method and application of the dehydroabietylamine-based epoxy resin. The preparation method is simple and high in operability and process controllability. The epoxy resin is particularly suitable for a composite material, an epoxy adhesive and a coating, and the prepared curing product has high mechanical property and thermal property. The formula I is shown in the specifications.

Description

Technical field [0001] The invention relates to the field of epoxy resin and its preparation, in particular to an epoxy resin based on dehydrorosinamine and its preparation method and application. Background technique [0002] Bio-based materials use renewable resources as the main raw materials. While reducing the consumption of petroleum resources in the plastic industry, it also reduces the environmental pollution of petroleum-based chemical raw materials during the production process, and has the dual effects of saving petroleum resources and protecting the environment. As early as a few years ago, the United States, Japan, and the European Union successively passed strategic bills and standards such as the Biomass Research and Development Act, the Biotechnology Strategy Outline, and the European Environmental Standard EN13432 to promote the healthy development of the economy and the environment. In my country, Premier Wen Jiabao made a solemn promise to the world at the end ...
