Abstract

The invention discloses a citric ester plasticizer and a preparation method thereof, belonging to the fields of plastic aids. The citric ester plasticizer is acetyl monoglyceride citrate and has the structure as shown in specifications, wherein n is 1 to 7 and m is 6 to 16. A glycerin fatty acid ester long-chain structure is inserted into the acetyl monoglyceride citrate of the plasticizer, so compared with the traditional citric ester plasticizers (TBC, ATBC and TEC), the citric ester plasticizer has the advantages that the problems that the citric ester plasticizer is easy to separate out and large in migration are solved; the processability and the product performance are greatly improved; and the application range of the products is enlarged.

Description

technical field

[0001] The invention relates to an additive or auxiliary agent for the plastic industry, in particular to an environmentally friendly and nontoxic citrate plasticizer, which is mainly used in food packaging plastics, medical equipment and children's toys, and belongs to the field of plastic auxiliary agents. Background technique

[0002] Citrate plasticizers are safe and non-toxic, and are one of the first-choice environmentally friendly plasticizers in the plastics industry at home and abroad. At present, the main varieties are tributyl citrate (TBC), acetyl tributyl citrate (ATBC) , Triethyl citrate (TEC). Although tributyl citrate (TBC), acetyl tributyl citrate (ATBC), and triethyl citrate (TEC) have excellent plasticizing effects and good cold resistance, light resistance, water resistance, and enzyme resistance , but compared with phthalate plasticizers, there are problems such as easy precipitation and large migration, and its volatility is relatively ...
