Description of DPGDB (Dipropylene Glycol Dibenzoate):
FIELD OF THE INVENTION:
The present invention relates to a non-phthalate plasticizer triblend comprising dibenzoate plasticizers, in specific proportions, all of which are compatible with each other and can be utilized in a variety of polymer applications traditionally requiring plasticizers, including but not limited to plastisols, adhesives, caulks, architectural coatings, industrial coatings, OEM coatings, inks, overprint varnishes, other coatings, polishes and the like.
The inventive plasticizer blends improve performance properties of the polymer, such as processability and stain and extraction resistance, among others.
The invention is also directed to polymeric compositions comprising the plasticizer triblend, such as plastisols and adhesives.
BACKGROUND OF THE INVENTION:
Plasticizers, as polymer additives, are established main line additives and have been known for more than a century. Most high volume plasticizers have been developed in the last seventy years, primarily for use with vinyl and other polymeric substances.
Significant volumes are sold, and plasticizers are used more than any other type of polymer additives, particularly in polyvinyl chloride (PVC) applications.
PVC can be formulated into a tremendous number of products and is useful in innumerable applications.
Plasticizers provide versatility to PVC and are key ingredients and tools for the vinyl formulator.
They are used to adjust hardness (or softness), impart stain resistance, alter tensile properties (such as strength, elongation or flexibility) and processability as required for a multitude of applications, including without limitation flexible vinyl applications.
While hundreds of plasticizers have been produced, only a few remain having acceptable performance properties when combined with vinyl or other polymeric materials.
There are a number of different types of plasticizers:
1) general purpose
2) specialty types (such as high solvators)
3) secondary types (oils) and diluent types (isodecyl benzoate, for example).
Plasticizer additives are available in a wide variety of alternative chemistries.
In addition to chemistry type, plasticizers are categorized and distinguished based on their ability to solvate dispersed solid polymers and/or their gelation and fusion temperatures in plastisols.
Gelation and fusion temperatures dictate the speed of production and are influenced by the solvating power of the plasticizer.
By way of example, the gelation and fusion temperatures of a plastisol containing a dibenzoate plasticizer will be lower than a plastisol containing a general purpose phthalate, thus enabling speed of processing in that particular application.
Plasticizers serve as a vehicle for the dispersion of resin (polymer) particles, such as PVC.
The dispersion is initially a two-phase, heterogeneous system.
Use of plasticizers in polymeric dispersions promotes the formation of homogeneous systems and polymer fusion occurs upon heating.
The higher the solvating power, the lower the temperature at which a homogeneous system is fused, which, in turn, decreases the residence time and increases the speed at which polymeric compositions can be processed into an end product, resulting in a faster, more efficient and economical process.
General purpose plasticizers provide an excellent compromise between performance characteristics and economy for most applications.
Some examples include: bis (2-ethylhexyl phthalate) (DEHP or DOP), diisononyl phthalate (DINP), dioctyl phthalate (DNOP), diisodecyl phthalate (DIDP), dipropylheptyl phthalate (DPHP), di-2-ethylhexyl terephthalate (DOTP or DEHT), and diisononyl-1,2 cyclohexane dicarboxylate (DIDC or DINCH®) (as described in U.S. Pat. No. 7,855,340).
General purpose phthalates dominate the volume of plasticizers purchased every year and are most often selected for compounding flexible vinyl.
Yearly, plasticizer production is in the area of 12 billion pounds, and the general purpose phthalate DOP accounts for about half of the pounds of plasticizer consumed, despite pressure from health and environmental issues encountered with the use of general purpose phthalates.
In view of the ongoing scrutiny of phthalate use, a need has developed for phthalate alternatives.
Both DOTP and DIDC are contenders for phthalate replacement in the general purpose market.
These two plasticizers are considered “next generation”, general purpose “non-phthalate” plasticizers.
Even though DOTP, chemically, is a phthalate, it is not an orthophthalate, the use of which is subject to increasing regulatory pressure.
These “next generation” phthalate alternatives are viable; however, they do not always give the performance desired in vinyl compositions, particularly in plastisols (i.e., they have poorer compatibility, slow speed, high gel temperatures, low gel strength).
Blends of plasticizers can be used to adjust performance, although there may be some limits to this approach.
In addition to DOTP and DIDC, sustainable, “green” types of plasticizers are also contending for the general purpose plasticizer market.
Examples include plasticizers based on castor oil and soybean oil.
Some applications, however, require performance that cannot be achieved by use of a general purpose plasticizer alone.
Applications that require better resistance to oils and solvents are one such example.
General purpose phthalates are easily extracted by nonpolar solvents such as hexanes, such that alternative plasticizers would be a much better choice.
There is also a need for plasticizers that are higher solvators for PVC and other polymer applications.
Specialty type plasticizers have been developed to fulfill the need for high solvators, the most popular being lower molecular weight phthalates.
An example of such a plasticizer is butyl benzyl phthalate (BBP), which is often employed as a high solvating plasticizer.
Di-n-butyl phthalate (DBP) and diisobutyl phthalate (DIBP) are also useful high solvator, specialty type plasticizers.
Other examples of non-phthalate, high solvating plasticizers include some citric acid esters, alkyl sulfonic acid esters, and certain phosphates.
Dibutyl terephthalate (DBTP) and N-alkyl pyrrolidones have also been proposed as a specialty type, high solvator plasticizers.
All of the high solvator plasticizers (regardless of type) add value to vinyl compositions that traditional general purpose plasticizers cannot.
Even so, many of the high solvator plasticizers are phthalates, for which safer alternatives are being sought.
Benzoate ester plasticizers have also been developed as specialty type plasticizers.
Benzoate plasticizers have been recognized since the 1940's as useful plasticizers for PVC applications, and subsequently some of these benzoate plasticizers were commercialized.
Benzoate plasticizers are well established and have now been in use in PVC applications for decades.
By their nature, benzoate plasticizers are non-phthalates; however, they were not created nor specifically established on that basis and were in use well before the demand for phthalate alternatives began.
Benzoate plasticizers include monobenzoates and dibenzoates, among others.
Monobenzoate esters useful as plasticizers include: isodecyl benzoate, isononyl benzoate, and 2-ethylhexyl benzoate.
“Half ester” monobenzoates include dipropylene glycol monobenzoate and diethylene glycol monobenzoate, which are byproducts of the production of dibenzoates, but which, most of the time, are not objects of production.
Monobenzoates are not generally noted for being high solvators, although they may be used in conjunction therewith.
Monobenzoates are also not as useful as dibenzoate plasticizers, because they are less compatible than the corresponding dibenzoate with PVC.
However, the half esters are compatible with emulsions polymers, such as acrylic and/or vinyl ester polymers.
Classically, dibenzoate plasticizers function well as high solvating plasticizers and are recognized today as some of the best high solvators for PVC applications.
Historically, diethylene glycol dibenzoates (DEGDB) and DPGDB (Dipropylene Glycol Dibenzoate)s (DPGDB) esters are well known and have been used in many applications in the past, including the vinyl industry.
DEGDB is an excellent plasticizer, but due to its high freeze point, blends with DPGDB were also developed to capitalize on the utility and lower cost of DEGDB.
Several years ago a blend of DEGDB, DPGDB and triethylene glycol dibenzoates (TEGDB) was introduced as a high solvating dibenzoate blend.
Benzoate ester plasticizers, alone or in a blend with other plasticizers, are commercially available and are described in the literature and in prior patents.
Plastisol and organosol compositions, adhesives, caulks, polishes, inks, and a wide variety of coatings containing benzoate plasticizers are also known in the art.
