Problems solved by technology

[0004] Isosorbide plasticizers are a new class of plasticizers. Isosorbide plasticizers have comparable plasticizing effects to phthalate derivatives and terephthalate derivatives, but isosorbide Ester plasticizers use isosorbide as raw material in the preparation process, and the market price of isosorbide is relatively high, which largely inhibits the application of isosorbide ester plasticizers

preparation example Construction

[0021] The invention provides a kind of preparation method of isosorbide plasticizer, comprises the following steps:

[0022] (1) dehydrating sorbitol under the action of an acidic catalyst to obtain sorbitan; the temperature of the dehydrating reaction is 60-180° C.;

[0023] (2) mix the sorbitan and fatty acid that described step (1) obtains, carry out esterification reaction under the effect of acidic catalyst, then carry out neutralization treatment to the product of described esterification reaction, obtain isosorbide ester plasticized agent; the temperature of the esterification reaction is 100~180°C;

[0024] The acid catalyst in the step (1) and step (2) is independently sulfuric acid, phosphoric acid, trifluoromethanesulfonic acid, trifluoroacetic acid, sulfamic acid or p-toluenesulfonic acid.

[0025] In the present invention, unless otherwise specified, each raw material component is a commercially available product well known to those skilled in the art.

Abstract

The invention provides an isosorbide plasticizer and a preparation method and application thereof. The preparation method includes following steps: allowing sorbitol to be in dehydration reaction under action of an acidic catalyst to obtain dehydrated sorbitol, wherein temperature of dehydration reaction is 60-180 DEG C; mixing dehydrated sorbitol with fatty acid, allowing esterification reactionunder action of an acidic catalyst, and neutralizing to obtain the isosorbide plasticizer, wherein temperature of esterification reaction is 100-180 DEG C. Sorbitol rather than isosorbitol is used asa raw material, so that production cost of the isosorbide plasticizer is lowered effectively. The isosorbide plasticizer has effects equivalent to common plasticizers in the prior art.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an isosorbide plasticizer and a preparation method and application thereof. Background technique [0002] Since the 20th century, the rapid development of polymer materials has become an indispensable substance in life and industrial production, but most of the directly synthesized polymer materials need to be modified to improve the quality of the prepared polymer materials. performance, such as flexibility, rigidity, etc. [0003] Commonly used polymer modifiers include plasticizers. Plasticizers are a kind of polymer material additives. Adding plasticizers in plastic processing can increase the flexibility of the prepared polymer materials and facilitate processing. Common plasticizers include phthalate derivatives and terephthalate derivatives. Although the above-mentioned plasticizers have a good plasticizing effect, the above-mentioned plasticizers are toxic to a certain ...
