COMPLETE SPECIFICATION STANDARD PATENT Soo:% 9 0 00 06 go Application Number: Lodged: Invention Title: PEMEATON REDUCING THERMOPLASTIC COM9POSITION m em *e e a S.
The following statement is a full description of this invention, including the best method of performing it known to us see' C 55 es C em 9 Se em 345-158 PERMEATION REDUCING THERMOPLASTIC COMPOSITION BACKGROUND OF THE INVENTION Polyethylene is a favored material used in constructing containers. It is cheaply produced as molded or extruded.
However, polyethylene has serious drawbacks. When certain fluids such as hydrocarbon based materials are packaged in polyethylene containers, they have a tendency to seep through the container wall. This is due to the permeable nature of polyethylene.
SUMMARY OF THE INVENTION It is an object of the invention to provide a thermoplastic additive which when blended with a thermoplastic serves as a
I
10 barrier to the permeation of fluids, and in particular, *"tI hydrocarbon based materials.
It is a further object of the invention to provide a drum, bottle, container or the like capable of resisting permeation of fluids, and particularly, hydrocarbon based materials.
It is a further object of the invention to provide a thermoplastic additive which can be formed into a liner for 'containers of other materials, such as metal and paper products, which provides resistance to fluid permeation.
added to thermoplastics, particularly, polyethylene. T additive is comprised of a carrier thermoplastic olyvinylidine C, fluoride, and aluminum stearate as a tie t, binding the e polyvinylidine fluoride and the car -r thermoplastic.
It is also possible to the blend into a liner suitable for lining metal drum d containers of other materials, thereby serving as ext easure of protection against permeation.
Al um stearate is used as an agent capable of gelling or 4t1r/1 BI -t bh 4 V1-^ I _rn-n'V la The present invention therefore provides a thermoplastic blend to be added to a hydrocarbon based carrier thermoplastic material to reduce permeation exhibited by the hydrocarbon based carrier thermoplastic material, the blend to be added to the hydrocarbon based carrier thermoplastic being comprised of polyvinylidine fluoride, a thermoplastic resin consisting essentially of the hydrocarbon based carrier thermoplastic material, and aluminum stearate.
It is also possible to form the blend into a liner suitable for lining metal drums and containers of other materials, thereby serving as extra measure of 10 protection against permeation.
Aluminum stearate is used as an agent capable of gelling or thickening aliphatic and aromatic hydrocarbons. In the present see *.ee
S.
S S I invention, its presence as an additive to thermoplastics or to thermoplastic liners reduces permeation through the container walls. If aliphatic or aromatic hydrocarbons penetrate the interior container wall or interior liner, the presence of aluminum stearate would cause a localized thickening, thereby preventing permeation.
EXAMPLE
The additive is prepared by mixing polyvinylidine fluoride (PVDF) and aluminum stearate with the carrier thermoplastic. The PVDF can be in either powderized or pelletized form. In this example, the thermoplastic is high molecular weight high density polyethylene (HMW-HDPE). The components of the blend were mixed *S in the following ratio: C' HMW-HDPE 52 lbs.
se* 15 PVDF 48 lbs.
Aluminum stearate 56 grms/cwt.
S SO Prior to mixing, the blend is covered. After mixing of the additive, it is suitable for a subsequent blending with a resin of the carrier. The subsequent blending creates a thermoplastic composite that resists and reduces permeation through its walls.
e6 It is preferred that after the subsequent mixing with the carrier
S
thermoplastic, the additive comprise 3 to 6% of the total composition of the subsequent composite.
The blend may also be used as a thermoplastic liner for 5 36 containers of other materials. The liner is applied to the containers by means known by those skilled in the art.
TEST DATA Three drums were tested to determine the amount of permeation through the drum walls.
i erns 15
S
is *r 6S se g is The drums were filled with xylene and then stored for a period of a year. Data reflecting the percentage of fluid I permeating through the drum was compiled on a intermittent basis.
S Drum #1 was a -ontrol drum possessing no permeation i resistant additives. Drum #2 possessed a 3% permeation resistant 1 additive as disclosed in the invention. Drum #3 possessed a 6% permeation resistant additive as disclosed in the invention.
S1 year day/50°C 12 weeks/50°C at ambient Drum #1 0.7% loss 2.08% loss 6.0% loss 3% Drum #2 0.4% loss 1.1% loss 4.7% loss I6% Drum #3 0.19% loss 0.58% loss 4.6% loss As can be seen, the drums containing the additive exhibit a resistance to permeation. The additive brings the drums into compliance with Department of Transportation regulations, which set a maximum of 0.5% loss at 50'C for a thirty day period for hazardous materials, and 2% loss at 50°C for a thirty day period at for non-hazardous materials.
