Embodiment 1

[0037] Step 1, weigh 100g Chinese tallow tree oil, 10g 85% formic acid solution, 50g n-butanol, 4g deionized water and 0.3g 85% phosphoric acid solution catalyst and add it to a 250mL reactor, then add 30% hydrogen peroxide dropwise under vigorous stirring The solution was 45g, the rate of addition was 30ml / h, and then the reaction temperature was kept at 50°C for 3.5h. After the reaction, the crude product was left to stand and separated, and the oil phase was washed with 2% sodium bicarbonate solution and deionized water until neutral, and then dehydrated by distillation under reduced pressure at 80° C. to obtain tallow tree oil polyol.

[0038] Step 2, weigh 30g tallow oil polyol, 0.2g boron tetrafluoride, nitrogen protection, stir and heat to 75°C, add 25g glycidol dropwise at a rate of 30ml / h, then heat the mixture to 100°C for 3h, Vacuum distillation gives tallow oil-based hyperbranched polymer (WOH).

[0039] Step 3: Weigh 20g of WOH and 23g of acetic anhydride into a ...

Embodiment 2

[0041] Step 1, take by weighing 100g Chinese tallow tree oil, 20g acetic acid solution, 30g ethanol, 3g deionized water and 0.3g 85% phosphoric acid solution catalyst and add in 250mL reactor, then drip 45g of 30% hydrogen peroxide solution under vigorous stirring condition, The dropping rate was 15ml / h, and then the reaction temperature was kept at 30°C for 6h. After the reaction, the crude product was left to stand and separated, and the oil phase was washed with 2% sodium bicarbonate solution and deionized water until neutral, and then dehydrated by distillation under reduced pressure at 80° C. to obtain tallow tree oil polyol.

[0042] Step 2, weigh 30g tallow oil polyol, dissolve 0.2g boron tetrafluoride in dimethyl sulfoxide under nitrogen protection, stir and heat to 75°C, add 18g ethylene glycol diglycidyl ether dropwise at a rate of 40ml / h , and then the mixture was heated to 100 ° C for 4 h, and the intermediate product WOH was obtained by distillation under reduced ...

Embodiment 3

[0045] Step 1, weigh 100g tallow tree oil, 10g 85% formic acid solution, 50g n-butanol, 4g deionized water and 0.3g 85% phosphoric acid solution catalyst and add it to a 250mL reactor, then add 70% hydrogen peroxide dropwise under vigorous stirring The solution was 30g, the rate of addition was 50ml / h, and then the reaction temperature was kept at 50°C for 3.5h. After the reaction, the crude product was left to stand and separated, and the oil phase was washed with 5% sodium bicarbonate solution and deionized water to neutrality, and then dehydrated by distillation under reduced pressure at 80° C. to obtain tallow tree oil polyol.

[0046] Step 2: Weigh 30g of tallow tree oil polyol, 0.2g of sodium methoxide, under nitrogen protection, stir and heat to 75°C, add 30g of glycidol dropwise at a rate of 30ml / h, then heat the mixture to 100°C for 5h, depressurize Distillation affords the intermediate WOH.

[0047] Step 3: Weigh 20g of WOH and 20g of maleic anhydride into a three-n...

Abstract

The invention discloses a sapium sebiferum oil-based hyperbranched polyester plasticizer and a preparation method thereof. The preparation method comprises: synthesizing sapium sebiferum oil polyol byusing industrial woody grease resource sapium sebiferum oil as a raw material through a one-step method; adding glycidyl ether and a catalyst, and synthesizing a hyperbranched polymer by adopting a solvent-free one-pot method under the protection of nitrogen; and continuously carrying out a hydroxyl-terminated modification reaction to prepare the sapium sebiferum oil-based hyperbranched polyesterplasticizer product. According to the invention, the raw materials are wide in source and renewable and do not depend on petroleum; the byproducts in the preparation process are few, the product quality is stable, the process is simple and reasonable, and the energy consumption is low; and the product is non-toxic, environment-friendly, good in heat resistance and durability and excellent in plasticizing performance, and has good application prospect.

Description

technical field [0001] The invention relates to a development and preparation technology of a non-toxic and environment-friendly grease-based plasticizer, in particular to a tallow oil-based hyperbranched polyester plasticizer and a preparation method thereof. Background technique [0002] Plasticizers are functional additives that are added to polymers to improve their flexibility, plasticity, processability, stretchability and other properties. They are mainly used in polyvinyl chloride (PVC) products. Since the 1940s, many studies have found that general-purpose plasticizers phthalates are easy to migrate from PVC substrates to external media in contact with them or released into the environment through volatilization, seepage, and dissolution. The migration of the plasticizer will lead to the deterioration of the product performance and greatly shorten the service life. In addition, the migrated phthalate plasticizers may act as endocrine disruptors, poisoning the liver...
