Embodiment 1

[0038] (1) Add 15mL of 30wt% hydrogen peroxide dropwise to 1.8g of tungsten powder and 7mL of water during stirring, then heat to 50°C and stir for 30 minutes. When the tungsten powder is completely dissolved, cool the solution and add 1.38g of 85% hydrogen peroxide of phosphoric acid and 14mL of water. Add 400 mL of soybean oil and 2.64 g of methyltrialkylammonium chloride into the reactor, and heat to 50° C. while stirring. Add the acidic tungsten powder solution into the above reactor with vegetable oil, then add 600mL of water, 120mL of phosphoric acid and 212mL of hydrogen peroxide. The mixture was also heated to 100°C and stirred rapidly for 6 hours. Then cool, add 250 mL of saturated sodium chloride solution and 500 mL of dichloromethane, separate the organic layer, and wash twice with 250 mL of saturated sodium chloride solution. The organic layer was dried with anhydrous magnesium chloride, filtered, and the solvent was distilled off under reduced pressure to obtain...

Embodiment 2

[0042] The preparation method of vegetable oil-based urethane acrylate is the same as in Example 1, only replace soybean oil with equimolar peanut oil in (1), the solvent is changed to toluene, the catalyst is changed to stannous octoate, and the polymerization inhibitor is changed to hydroquinone . The product is identified by infrared spectroscopy, when the isophorone diisocyanate (IPDI) isocyanate (NCO) infrared characteristic peak 2270cm -1 When it disappears, the reaction ends and peanut oil-based urethane acrylate is obtained. The yield was 82%.

Embodiment 3

[0044] (1) Add 10mL of 30wt% hydrogen peroxide dropwise to 1g of tungsten powder and 3mL of water during stirring, then heat to 30°C and stir for 30 minutes. When the tungsten powder is completely dissolved, cool the solution and add 1g of 85% phosphoric acid and 10 mL of water. Add 400 mL of soybean oil and 2 g of methyltrialkylammonium chloride into the reactor, and heat to 50° C. while stirring. Add the acidic tungsten powder solution into the above reactor with vegetable oil, then add 300mL of water, 100mL of phosphoric acid and 200mL of hydrogen peroxide. The mixture was heated to 100°C and stirred rapidly for 6 hours. After cooling, add 100 mL of saturated sodium chloride solution and 300 mL of dichloromethane, separate the organic layer, and wash twice with 100 mL of saturated sodium chloride solution. The organic layer was dried with anhydrous magnesium chloride, filtered, and the solvent was distilled off under reduced pressure to obtain the polyhydroxy soybean oil ...

Abstract

The invention relates to vegetable oil based polyurethane acrylic ester, belonging to the field of photosensitive polymer material. The vegetable oil based polyurethane acrylic ester is characterized in that the general chemical formula is Formula I, wherein R1, R2 and R3 are respectively chosen from alkane of C1-C18, at least one of the alkane is chosen from Formula II, R4 and R5 are respectively chosen from alkane of C1-C16, R6 is diphenyl methane-4,4'-diisocyanate, or hexamethylene diisocyanate, or isophorone diisocyanate or residue of 2,4-toluene diisocyanate with two isocyanate functional group removed, and R7 is 2-hydroxyethyl acrylate, or hydroxypropyl acrylate, or residue of pentaerythritol triacrylate with hydroxy functional group removed.

Description

technical field [0001] The invention relates to the field of photosensitive polymer materials, in particular to a vegetable oil-based polyurethane acrylate and its preparation method and application. Background technique [0002] Vegetable oil is obtained from the seeds, pulp or germ of plants by pressing or solvent extraction. Most of them are liquid at room temperature, and a few are semi-solid or solid. The main component is triglycerides of fatty acids, and the types of fatty acids mainly include oleic acid, linoleic acid, linolenic acid, palmitic acid, ricinoleic acid, etc. Fatty acids are a class of compounds composed of carbon, hydrogen, and oxygen, and are the main components of neutral fats, phospholipids, and glycolipids. According to the length of the carbon chain in the fatty acid molecular structure, it is divided into short-chain fatty acids (less than 6 carbon atoms in the carbon chain), medium-chain fatty acids (6-12 carbon atoms in the carbon chain) and lo...
