Abstract

Provided are a hemp seed oil-based double-crosslinkable resin monomer molecule and a preparation method thereof. Firstly, unsaturated hemp seed oil is enabled to be subjected to hydrolysis reaction toprepare unsaturated hemp seed oil acid, then the unsaturated hemp seed oil acid reacts with a proper amount of catalyst, an oxygen carrier formic acid and hydrogen peroxide to obtain hydroxyl-containing unsaturated hemp seed oil acid, the hydroxyl-containing unsaturated hemp seed oil acid reacts with a proper amount of catalyst, a polymerization inhibitor and glycidyl methacrylate to obtain a polyhydroxy hemp seed oil-based monomer,and the prepared polyhydroxy hemp seed oil-based monomer reacts with a proper amount of maleic anhydride to obtain the hemp seed oil-based double-crosslinkable resin monomer molecule. The hemp seed oil is selected as a raw material to prepare a multi-crosslinking resin monomer product, environment-friendly resources are fully utilized, the product can carry outdouble crosslinking reaction, and the cured product has excellent mechanical strength.

Description

technical field [0001] The invention belongs to the field of double-crosslinked curing systems in the field of macromolecules, and in particular relates to a hemp seed oil-based double-crosslinked resin monomer molecule and a preparation method thereof. Background technique [0002] In recent years, with the emergence of problems such as environmental pollution and the shortage of non-renewable resources, people have paid more and more attention to natural products. Biomass raw materials are not only rich in sources, renewable, but also cheap and biodegradable. Vegetable oils and fats contain a large amount of unsaturated fatty acids, such as oleic acid, linoleic acid, and oleic acid. Unsaturated fatty acids can undergo various types of chemical reactions such as halogenation, oxidation, hydrogenation, deoxygenation, polymerization, degradation, etc. At present, oil is widely used in the manufacture of paints, inks, emulsifiers, lubricants, etc., and a variety of oil-based...
