Embodiment 1

[0038] Condensation: Add 100g eugenol and 250g epichlorohydrin into a four-necked flask equipped with a thermometer, agitator and condenser, and add 1.5g hexadecyltrimethylammonium bromide, mix and stir, and heat up under nitrogen protection to 120°C, react for 3h; then cool the reaction system to below 80°C, add 88.2mL saturated NaOH solution to close the ring, control the temperature at 70-80°C, react for 2h; extract the obtained reaction solution twice with brine, dry, The excess epichlorohydrin was removed under reduced pressure to obtain an intermediate product, which was a light yellow transparent liquid at room temperature.

[0039] Oxidation: Dissolve the intermediate product in dichloromethane, add 129g m-chloroperoxybenzoic acid, and stir at 25°C for 48 hours; the obtained reaction solution is filtered to remove m-chloroperoxybenzoic acid, and then extracted with sodium bisulfite solution to starch potassium iodide The test paper does not turn blue, and then extracte...

Embodiment 2

[0045]Condensation: Add 100g eugenol, 35.2g sodium hydroxide and 300g epichlorohydrin into a four-necked flask with a thermometer, agitator and condenser, and add 1.5g hexadecyltrimethylammonium bromide, mix Stir, raise the temperature to 100°C under the protection of nitrogen, and react for 4 hours; the obtained reaction solution is extracted twice with brine, dried, and excess epichlorohydrin is removed under reduced pressure to obtain an intermediate product, which is a light yellow transparent liquid at room temperature.

[0046] Oxidation: Dissolve the intermediate product in dichloromethane, add 129g m-chloroperoxybenzoic acid, and stir at 0°C for 48 hours; the obtained reaction solution is filtered to remove m-chloroperoxybenzoic acid, and then extracted with sodium bisulfite solution to starch potassium iodide The test paper does not turn blue, then extracts with sodium carbonate solution, dries, and desolventizes under reduced pressure to obtain eugenol epoxy resin, wh...

Embodiment 3

[0048] Condensation: Add 100g eugenol and 270g epichlorohydrin into a four-necked flask equipped with a thermometer, agitator and condenser, and add 1.5g hexadecyltrimethylammonium bromide, mix and stir, and heat up under nitrogen protection to 120°C, react for 3h; then cool the reaction system to below 80°C, add 88.2mL saturated NaOH solution to close the ring, control the temperature at 70-80°C, and react for 2h; extract the reaction solution twice with brine, dry, reduce The excess epichlorohydrin was removed by pressure to obtain the intermediate product, which was a light yellow transparent liquid at room temperature.

[0049] Oxidation: Dissolve the intermediate product in dichloromethane, add 129g m-chloroperoxybenzoic acid, and stir at 0°C for 48 hours; the obtained reaction solution is filtered to remove m-chloroperoxybenzoic acid, and then extracted with sodium bisulfite solution to starch potassium iodide The test paper does not turn blue, and is extracted with sodi...

Abstract

The invention provides a eugenol epoxy resin and a preparing method and application thereof. The eugenol epoxy resin is prepared from a compound shown in the formula I in the description and / or a compound shown in the formula II in the description. The epoxy resin is free of biotoxicity, the mechanical property of the epoxy resin is similar to that of traditional epoxy resin, and the eugenol epoxy resin can replace traditional petroleum-based epoxy resin. The epoxy resin is liquid at the room temperature, and is beneficial to subsequent processing and application and capable of being used for preparing composites, paint, adhesives and the like.

Description

technical field [0001] The invention relates to a bio-based epoxy resin and its preparation method and application, in particular to a eugenol epoxy resin and its preparation method and application. Background technique [0002] Epoxy resin is one of the most widely used thermosetting resins. At present, the global annual output is more than 2 million tons, of which the output of bisphenol A epoxy resin accounts for more than 85%. Bisphenol A type epoxy resin is mainly prepared from bisphenol A and epichlorohydrin as raw materials. Although bio-based epichlorohydrin has been industrialized and its output is increasing, more than 67% of bisphenol A is still completely dependent on petrochemical resources. In recent years, there have been frequent reports that bisphenol A poses a great threat to the health of living organisms. Therefore, bisphenol A epoxy resins have been banned by many countries in the world for use in related fields that come into contact with food and huma...
