Ultra-low petroleum plastics

a petroleum plastic and ultra-low technology, applied in the field of plasticlike materials, can solve the problems of rapid depletion of the world's petroleum reserves, affecting the quality of plastic products, and fluctuating the price of plastic production with the price of oil, so as to reduce the content of petroleum-derived materials, improve the chemical properties such as fire retardancy and smoke suppression, and improve the effect of physical and mechanical properties

Benefits of technology

[0007] In accordance with the foregoing objectives and others, the present invention provides plastic-like materials having interesting physical and mechanical properties, chemical properties such as fire retardancy and smoke suppression superior to conventional plastics, and diminished petroleum-derived material content as compared to conventional plastics.
[0008] It has surprisingly been found that plastic-like materials comprising between about 20 to about 80% by weight of an inorganic salt can be obtained which have physical, mechanical, and chemical properties that are useful for many of the applications in which conventional plastics are employed. Some properties, such as fire retardancy, smoke suppression, toxicity of smoke release, and heat resistance are substantially improved as compared to conventional plastics. Importantly, the plastic-like materials or the invention are cheaper to produce than conventional plastics.

Problems solved by technology

The disadvantages of such petroleum-derived products are well known and include, for example, the rapid depletion of the world's petroleum reserves, the deleterious environmental consequences resulting from the poor biodegradability of petroleum-derived plastic materials, and the fluctuating cost of plastic production with the price of oil.
Even conventional “low petroleum” plastics such as polyvinyl chloride (“PVC”), which comprises approximately 43% by weight petroleum feedstock products, suffer from these disadvantages.
Unfortunately, satisfactory alternatives to petroleum-derived plastic materials have not heretofore been commercially viable.

Preparation of Micronized Ammonium Sulfate

[0046] Approximately 20 pounds of ammonium sulfate and approximately 15 pounds of glass balls with sizes ranging from 0.5 to 1 inches were placed in a standard cement mixer. The ammonium sulfate was ground for about four hours. The material was then passed through a 500 Tyler mesh screen. Substantially all of the material passed through the screen indicating that the maximum particle size was about 25 μm. This material was used to make the materials described in the following examples.

example 2

[0047] Approximately 60 gm of micronized ammonium sulfate from Example 1 was mixed with approximately 21 gm of a standard compounded PVC (see Table II) and approximately 19 gm pounds of the 2-ethyl hexyl diphenyl plasticizer Santicizer® 141 (Ferro Corp.). The mixture was formed into sheets having a thickness of about 30 mil with twin rollers operating at 380° F. for about five minutes, or until homogeneous.

example 3

[0048] Approximately 55 gm pounds of micronized ammonium sulfate from Example 1 was mixed with approximately 26 gm pounds of a standard compounded PVC (see Table II) and approximately 19 gm pounds of the 2-ethyl hexyl diphenyl plasticizer Santicizer® 141 (Ferro Corp.). The mixture was formed into sheets having a thickness of about 30 mil with twin rollers operating at 380° F. for about five minutes, or until homogeneous.

[0049] This material was tested for fire retardancy by an independent laboratory with the Underwriters Laboratories (“UL”) flame test designated UL-94. The material received the highest UL-94 rating of V-0.

[0050] The material also passed the U.S. Government standard for flammability resistance FAR 25.853. That test involves subjecting a panel to edge burning by a flame maintained at 1550° F. for a period of 60 seconds and requires that the material be self-extinguishing before 15 seconds and that it be non-dripping. After subjecting the material to flame for 60 sec...

Abstract

Plastic-like compositions having ultra-low contents of petroleum derived materials are provided. The materials comprise up to about 80% by weight of an inorganic salt having an average particle size between about 0.001 and about 300 μm and a plastic binder. The compositions have a low propensity to ignite or smoke in the presence of heat or flame.

Description

FIELD OF INVENTION [0001] The present invention relates generally to plastic-like materials having diminished contents of petroleum-derived products. The invention also relates to fire retardant plastic-like materials. BACKGROUND OF THE INVENTION [0002] Conventional plastic materials comprise synthetic polymers derived predominately from petroleum. The disadvantages of such petroleum-derived products are well known and include, for example, the rapid depletion of the world's petroleum reserves, the deleterious environmental consequences resulting from the poor biodegradability of petroleum-derived plastic materials, and the fluctuating cost of plastic production with the price of oil. Even conventional “low petroleum” plastics such as polyvinyl chloride (“PVC”), which comprises approximately 43% by weight petroleum feedstock products, suffer from these disadvantages. [0003] Accordingly, it has long been desirable to decrease the petroleum content of plastic products. Unfortunately, ...
