Embodiment 1

[0056] (1) Preparation method of the compound catalyst: Weigh 10g zinc acetate and 2g antimony trioxide in a 50ml beaker, and stir at room temperature by electromagnetic stirring, mix well, and set aside.

[0057] (2) Esterification reaction: add 1mol citric acid, 1mol n-butanol, 3mol octanol, 0.5mol cyclohexane into a 1000ml four-neck flask equipped with temperature-controlled oil bath, stirrer, water separator and reflux condenser Heat to 30°C, stir, and after the citric acid is completely dissolved and mixed with the alcohol evenly, take a sample to measure the initial acid value A of the reaction solution 0 , Then add 6.7g of the compound catalyst prepared in step (1), heat to 100°C, stir to produce reflux. When the water produced by the reaction starts to be separated from the water trap, it is counted as the start time of the esterification reaction. Until completely anhydrous is separated from the trap, the reaction is deemed to have reached the end point (6h). Then take ...

Embodiment 2

[0063] (1) In the esterification reaction, add 1 mol of citric acid, 2 mol of n-butanol, 2 mol of octanol, 0.5 mol of cyclohexane and 6.2 g of the compound catalyst prepared in step (1) in Example 1. Other steps and conditions and implementation Example 1 is the same, the esterification rate is 99.32%.

[0064] The obtained modified citrate ester was analyzed and checked by GC-MS, and its components were:

[0065] Component

Embodiment 3

[0067] (1) In the esterification reaction, add 1 mol of citric acid, 3 mol of n-butanol, 1 mol of octanol, 0.5 mol of cyclohexane and 5.6 g of the compound catalyst prepared in step (1) of Example 1, other steps and conditions and implementation Example 1 is the same, and the esterification rate is 99.12%.

[0068] The obtained modified citrate ester was analyzed and checked by GC-MS, and its components were:

Abstract

The invention relates to a novel plasticizer and a preparation method thereof, which overcome the defects that the existing low-carbon alcohol citrate plasticizers are non-transference-resistant, high in volatility and high in economic costs and high-carbon alcohol citrate plasticizers are low in efficiency. The novel plasticizer contains at least two types of citrate compounds. The novel plasticizer disclosed by the invention can be used as a plasticizer, and widely applied to the fields of plastic compositions and adhesives and the like.

Description

Technical field [0001] The invention relates to a novel polymer material auxiliary agent and a preparation method thereof, in particular to a novel plasticizer and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is widely used in all aspects of production and life because of its better economy, such as drinking water pipes, medical products (infusion bags, infusion tubes, medical packaging, etc.), food packaging (cling film, preservation Bags, gaskets, etc.), children’s toys (including import toys, inflatable toys), cultural and sports goods (zippered transparent file bags, plastic skipping ropes, plasticine, swimming rings), plastic raincoats, rain boots, etc. From the above applications, the safety of PVC products is very important to people. [0003] Traditional PVC products are mainly produced by PVC resin, plasticizer, and heat stabilizer through certain processing methods. At present, PVC resin produced in China is basically non-toxic, a...
