Abstract

Electrically conductive or static dissipative coating, films, or laminae in a laminate construction suitable for packaging of sensitive electronic components. The electrical conductive or static dissipative properties are achieved by including an effective amount of a quaternary ammonium compound into a base resin.

Description

CONDUCTIVE OR STATIC DISSIPATIVE COATING
Background of the Invention
1. Field of the Invention
This invention relates to a film, specifically a self-sustaining film or a laminae in a
laminated construction or a coating for such laminated construction which is electrically conductive and/or possesses static electricity dissipative properties. These materials can be used
especially to package electronic components which may be affected by or damaged by the buildup of static electricity during transportation, handling or storage of the electronic part.
2. Background of the Invention
Resinous materials, e.g. polymeric materials, are known to be useful for formation of coatings, self-sustaining films, laminae in laminated constructions and coating thereon. However, inherent in the use of polymeric materials is the fact that they are typically non- conductive to electricity and, in fact, such materials are used widely as insulators because of
these non-conductive properties.
Prior attempts at imparting electrically conductive properties to polymers include the inclusion of conductive materials, especially a material such as carbon or similar material, e.g. graphite, as a filler to the polymeric material. The inclusion of a material such as carbon is only
effective if it is provided in such an amount (by weight or volume) and dispersed uniformly throughout the polymeric material so as to form a continuous pathway for transmission of electrical energy. The inclusion of such large amounts of filler and the problem of uniformly dispersing a material such as carbon greatly influences the conductive properties of the resulting composite material. Due to its nature, i.e. its inherent color, the use of carbon also imparts a predominately black color to any polymeric material into which it is incorporated in electrically
conductive amounts. Therefore, there is a requirement in the packaging industry for materials which are more aesthetically pleasing than a black plastic film. Summary of the Invention
A film or coating which is composed primarily of a polymeric material is provided with conductive or static dissipative properties having particular utility for packaging electronic components, which are subject to deterioration of properties by build-up of static electricity
during storage, shipping and handling and/or electrically conductive materials in a form of a self- sustaining film, as a laminae in a laminated construction or as a coating on paper or in a
laminated construction for the purpose of imparting conductive or static dissipative properties to the polymeric material. Such polymeric material having the conductive or static dissipative properties can be used as packaging materials, especially for packaging electronic components. Detailed Description of the Preferred Embodiments
Polymeric materials such as acrylic based polymers, especially methylmethacrylate containing polymers, are excellent for forming coatings and films because of their physical properties, especially their optical clarity. These properties make it desirable to use such materials as a component for packaging after manufacture. However, such polymeric materials do not conduct or transmit electrical energy and are generally known as "insulators," i.e. are non-
conductive to electrical current.
The present invention discloses a novel formulation for imparting electrical conductivity
or static dissipative properties to polymeric materials by mixing between about 1 to about 10 wt % of a material imparting a surface resistivity (as measured by ASTM D-257 test method conducted at 12% relative humidity) so as to have a static dissipative property of less than 1012 ohms/sq and a conductive property of less than 105 ohms/sq. A material suitable for mixing with the polymeric material is a quaternary ammonium compound. These quaternary ammonium compounds, in a solvent/carrier of an alcohol, preferably an isopropanol/ethanol mix, results in a liquid material which is easily mixed with the polymeric material. The quaternary ammonium
containing liquid preferably contains about 41% by weight alcohol and most preferably 40% isopropanol and 1% ethanol. Quaternary ammonium salts have been used as softeners, especially in laundry formulations, or as applied to paper or foam substrates introduced during drying of laundered clothes. However, no use of these materials as a component of a film, laminate or coating has been known prior to the invention. A suitable material can be obtained from ACL Inc., 1960 E. Devon Avenue. Elkgrove Village, Illinois 60007, under the name "STATICIDE 3000G." Such a material is commercially available in liquid concentrate form appearing as a clear yellow substance with a pleasant odor, having an evaporation rate greater than water. As
sold, "STATICIDE 3000G" has a specific gravity of 0.97, a density (g/ml) of 0.97, a vapor pressure (mm) at 20°C of 36 and a vapor density of 2.1. Percent volatiles (by volume) is about
40% with a pH of 7.1±l.
After mixing the quaternary ammonium containing liquid with the polymeric material, the resulting composition can then be formed into a self-sustaining film or used as a laminae of
a lamination construction or as a coating for paper or a lamination construction. When used in a lamination construction, the conductive or static dissipative containing material of the present
invention should preferably be used as the outer layer, i.e. on one or both sides of the film. Between the outer layers of the film, additional laminae may include a metallicized or non- metallicized surface and one or more layers of plastic film, fabric, non- woven material or paper, each of which is either coated or non-coated with coatings. The mixture of quaternary ammonium containing liquid and other components can be formed into a film, applied as a coating or formed into a laminae by conventional techniques known to the art for making other
polymeric films, coatings and/or laminae.
Typical requirements of a self-sustaining film would be one having a thickness between about 0.5 to about 500 mils and having a tensile strength (measured by ASTM D-882 test method of 0-100 lbs. per square inch). Puncture resistance (as measured by FTMS 101C method 2065) is 0-150 lbs. The haze (as measured by ASTM D-1003 test method) is clear to opaque; an optical
density (measured by the McBeth test method) of 0-4.0% and a light transmission (measured by ASTM D-1003 test method) of 0-100%. Seam strength of a film made into a package as tested
by ASTM D-882 test method should destruct.
The best mode contemplated by the inventor for carrying out the invention is illustrated
