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
The present invention relates to a kind of composite modified environmental protection plasticizer, belong to field of chemicals.
Background technology
Plasticizer is the important auxiliary agent of plastics industry.On market, the primary plasticizer having the call is that phthalic acid two is pungent
Ester (DOP), accounts for the 60% of total output.But the endocrine particularly reproduction merit that may interfere with the mankind the most under a cloud
Can, the most once suspected by american cancer institute (NCI) that after having carcinogenesis, its range was the most limited, in European Union and many
Developed country has started to disabling.In the world today, the mankind can be more and more higher to the standard of environmental requirement, develops and find more ring
Protect, safer DOP succedaneum has become as the inexorable trend in epoch.Di-2-ethylhexyl terephthalate (DOTP), diethylene glycol two
Benzoate (DEDB) is nontoxic environment-friendlyplasticizer plasticizer, and with regard to its performance, they have respective advantage, as DOTP has high absolutely
Edge, low volatility, extraction heat-resisting, cold-resistant, anti-；The different monooctyl ester of benzoic acid belongs to low fat chain esters, has viscosity reduction significantly to DEDB
Effect；DEDB antistatic, resistance tocrocking are notable, have prominent heat stability and low volatility, especially toxicity low.DEDB self
Viscosity is big, and freezing point is high, easily solidifies, can make troubles to use when ambient temperature is less than 15 DEG C.It is affected by, never has
To extensively application.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, it is provided that a kind of composite modified environmental protection plasticizer.
Its preparation method is simple, is widely used.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of composite modified environmental protection plasticizer, raw material includes each component that mass fraction is following: p-phthalic acid two is different pungent
Ester (DOTP) accounts for 17%～77%, and the different monooctyl ester of benzoic acid accounts for 3%-5%, diethylene glycol dibenzoate (DEDB) account for 20%～
80%.
In such scheme preferably, raw material includes each component that weight fraction is following: Di-2-ethylhexyl terephthalate
(DOTP) accounting for 45%, the different monooctyl ester of benzoic acid accounts for 5%, and diethylene glycol dibenzoate (DEDB) accounts for 50%.
When DEDB is used alone ambient temperature less than 15 DEG C time there is easily solidification, in-convenience in use shortcoming.The present invention sends out
Existing, the different monooctyl ester of DOTP, benzoic acid and DEDB carry out having during physical mixed good intersolubility, eliminate DEDB and are used alone and deposit
Shortcoming.
Present invention have the advantage that
1, a kind of new composite modified environmental protection plasticising is become after DOTP, the different monooctyl ester of benzoic acid, tri-kinds of plasticizer mixtures of DEDB
Agent.
2, in above-mentioned composite modified plasticizer, when DEDB adding the DOTP of >=20% and adding the different monooctyl ester of benzoic acid
When 3%, do not solidify when ambient temperature reaches 0 DEG C, easy to use.When diethylene glycol dibenzoate (DEDB) is used alone, ring
Just start solidification during border temperature 15 DEG C, therefore use after needing heating and melting, use after need to being heated to more than 15 DEG C melting.
3, different pungent as the DOTP and addition >=3% benzoic acid adding >=20% in DEDB in above-mentioned composite modified plasticizer
During ester, the intermiscibility with resin can be obviously improved.And it is the most to add DEDB amount, reduces cost the most.
4, preparation method of the present invention is simple.
Detailed description of the invention
Hereinafter the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred embodiment described herein is only used
In the description and interpretation present invention, it is not intended to limit the present invention.
