Embodiment 1

[0015] A kind of composite modified environment-friendly plasticizer, raw material comprises the diethylene glycol dibenzoate (DEDB) that mass fraction accounts for 80%, the diisooctyl terephthalate (DOTP) that mass fraction accounts for 17%, mass fraction Accounting for 3% isooctyl benzoate, the three are mixed and stirred to obtain the product. The composite modified plasticizer does not solidify at an ambient temperature of 0°C.

Embodiment 2

[0017] A kind of composite modified environment-friendly plasticizer, raw material comprises the diethylene glycol dibenzoate (DEDB) that mass fraction accounts for 20%, the diisooctyl terephthalate (DOTP) that mass fraction accounts for 77%, mass fraction Accounting for 3% isooctyl benzoate, the three are mixed and stirred to obtain the product. The composite modified plasticizer does not solidify at an ambient temperature of -5°C.

Embodiment 3

[0019] A kind of composite modified environment-friendly plasticizer, raw material comprises the diethylene glycol dibenzoate (DEDB) that mass fraction accounts for 50%, the diisooctyl terephthalate (DOTP) that mass fraction accounts for 45%, mass fraction Accounting for 5% isooctyl benzoate, the three are mixed and stirred to obtain the product. The composite modified plasticizer does not solidify at an ambient temperature of -5°C and can maintain good fluidity.

Abstract

The invention discloses a composite modified environment-friendly plasticizing agent, which is prepared from the following raw material ingredients in percentage by mass: 20 percent to 75 percent of dioctyl terephthalate (DOTP), 3 percent to 5 percent of isooctyl benzoate and 20 percent to 75 percent of di(ethylene glycol) dibenzoate (DEDB). The composite modified environment-friendly plasticizing agent has the following advantages that (1) three plasticizing agents, namely the DOTP, the isooctyl benzoate and the DEDB, are compounded to become a novel composite modified environment-friendly plasticizing agent; (2) in the composite modified plasticizing agent, when 20 percent or more of DOTP and 3 percent of isooctyl benzoate are added into the DEDB, curing cannot occur when the environment temperature reaches 0 DEG C; the use is convenient; (3) in the composite modified plasticizing agent, when 20 percent or more of DEDB is added into the DOTP, the intermiscibility with the resin can be obviously improved; in addition, more cost is reduced when more DEDB is added; (4) the preparation method is simple.

Description

technical field [0001] The invention relates to a composite modified environment-friendly plasticizer, which belongs to the field of chemicals. Background technique [0002] Plasticizers are important additives in the plastics industry. On the market, the main plasticizer with the largest demand is dioctyl phthalate (DOP), accounting for about 60% of the total output. However, in recent years, it has been suspected that it may interfere with human endocrine, especially reproductive functions, and has been suspected of carcinogenicity by the National Cancer Institute (NCI). Its use has been sharply limited, and it has been banned in the European Union and many developed countries. In today's world, human beings will have higher and higher standards for environmental protection. It has become an inevitable trend of the times to develop and find more environmentally friendly and safer DOP substitutes. Diisooctyl terephthalate (DOTP) and diethylene glycol dibenzoate (DEDB) are...
