Embodiment 1

[0038] Example 1 Preparation of HEAPTD-ESO

[0039] (1) Mix HEA and PTD at a ratio of 1.05:1, then add 0.15% p-methoxyphenol (MEHQ) as a polymerization inhibitor relative to the total mass of the mixture, and 1.4% triphenylene relative to the total mass of the mixture Phosphine (TPP) (or other catalysts), slowly heated to 100 ° C, the mixture slowly becomes a clear liquid;

[0040] (2) When the acid value of the reaction system in step (1) decreases and no longer changes, add epoxidized soybean oil. The amount of epoxidized soybean oil added is based on the number of carboxyl moles converted from the epoxy value to the actual acid value at 1.1:1 Then add triphenylphosphine and MEHQ respectively to ensure that the mass fractions are 1.4% and 0.15%, and the temperature rises to 120 °C. During the reaction, the acid value is continuously sampled and tested until the acid value drops to 5 mg / g, stop the reaction. The final product is light khaki viscous liquid, namely HEAPTD-E...

[0041] Example 2 Preparation of PETAPTD-ESO

[0042] (1) Mix PETA and PTD at a ratio of 1.08:1, then add 0.15% p-methoxyphenol (MEHQ) as a polymerization inhibitor relative to the total mass of the mixture, and 1.4% triphenylene relative to the total mass of the mixture Phosphine (TPP) (or other catalysts), slowly heated to 110 ° C, the mixture slowly becomes a clear liquid;

[0043] (2) When the acid value of the reaction system in step (1) decreases and no longer changes, add epoxidized soybean oil. The amount of epoxidized soybean oil added is based on the number of carboxyl moles converted from the epoxy value to the actual acid value at 1.1:1 Calculation of the ratio, and then add triphenylphosphine and MEHQ respectively, to ensure that the mass fractions are 1.4% and 0.15%, the temperature is controlled at 100 ℃, and the acid value is continuously sampled and tested during the reaction until the acid value drops to 5 mg / g, stop the reaction. The final product is lig...

[0044] Example 3 Preparation of HEASCA-ESO

[0045] (1) Mix HEA and succinic anhydride (SCA) at a ratio of 1.08:1, then add 0.15% p-methoxyphenol (MEHQ) as a polymerization inhibitor relative to the total mass of the mixture, and 1.4% relative to the total mass of the mixture % of triphenylphosphine (TPP) (or other catalysts), slowly heated to 110 ° C, the mixture slowly becomes a clear liquid;

[0046] (2) When the acid value of the reaction system in step (1) decreases and no longer changes, add epoxidized soybean oil. The amount of epoxidized soybean oil added is based on the number of carboxyl moles converted from the epoxy value to the actual acid value at 1.1:1 Calculation of the ratio, and then add triphenylphosphine and MEHQ respectively, to ensure that the mass fractions are 1.4% and 0.15%, the temperature is controlled at 105 ℃, and the acid value is continuously sampled during the reaction until the acid value drops to 5 mgKOH / g, stop the reaction. The final pr...

Abstract

The invention discloses an acrylic acid ester modified epoxy soybean oil, its preparation method and an application thereof. According to the preparation method of the acrylic acid ester modified epoxy soybean oil, acrylate monomer bearing a hydroxyl group reacts with acid anhydride to obtain a half-ester intermediate, and the half-ester intermediate reacts with epoxy soybean oil to obtain the acrylic acid ester modified epoxy soybean oil. The acrylate monomer bearing a hydroxyl group is hydroxyethyl acrylate, hydroxyethyl methacrylate, pentaerythritol triarylate, hydroxypropyl acrylate, hydroxypropyl methacrylate, trimethylol propane diacrylate or trimethylol propane dimethacrylate. Acid anhydride is o phthalic anhydride, succinic anhydride, methyl hexahydrophthalicanhydride, hexahydrophthalic anhydride or tetrahydrophthalic anhydride. The acrylic acid ester modified epoxy soybean oil has a novel structure. When applied in paper printing ink, the acrylic acid ester modified epoxy soybean oil can improve adhesive force of a cured film and also can improve wetability of pigments and remarkably minimize occurrence of misting. The preparation method helps widen the application range of the modified epoxy soybean oil.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an acrylate-modified epoxy soybean oil and a preparation method and application thereof. Background technique [0002] Polymer materials have excellent properties and are widely used in cutting-edge technology, national defense construction, and national economy. They have become indispensable and irreplaceable materials for modern technology and life. At present, most synthetic polymer materials use non-renewable petroleum resources as raw materials, which have brought serious problems to the environment. Furthermore, it is estimated that humans are currently depleting petroleum resources at a "non-sustainable" rate 100,000 times faster than the natural rate of production. After entering the 21st century, the green industrial revolution, which focuses on saving resources and energy, developing a low-carbon economy, and protecting the balance of the ecological enviro...
