Description
SPECIFICATION
Flame retardant thermoplastic compositions
This invention is directed to a flame retardant thermoplastic composition and, in particular, a composition containing an organic sulfonate flame retardant additive in admixture with one or more compounds selected from the group comprising a polyarylsulfone, a polyarylethersulfone, a polyphenylsulfide, blends of a polyarylethersulfone and a polyarylsulfone, blends of a polyarylethersulfone and a polyphenylsulfide, blends of a polyarylsulfone and a polyphenylsulfide, blends of a polyarylenecarbonate and acrylonitrilebutadiene-styrene copolymer (ABS), blends of a polarylenecarbonate, acrylonitrile-butadiene styrene copolymer (ABS) and a polyarylsulfone, blends of a polyarylenecarbonate, acrylonitrile-butadiene-styrene copolymer (ABS) and a polyarylethersulfone, blends of a polyarylenecarbonate, acrylonitrile-butadienestyrene copolymer (ABS) and a polyphenylsulfide, and blends of a polyarylenecarbonate, acrylonitrilebutadiene-styrene copolymer (ABS), together with two or more compounds selected from the group comprising polyarylsulfones, polyarylethersulfones and polyphenylsulfides. The composition may additionally contain an organic halogen-containing flame retardant additive.
Background of the invention
With the increasing concern for safety, there is a positive move toward providing safe materials for public and household use. One particular area of need is that of providing flame resistant or flame retardant products for use by the ultimate consumer. As a result of this demand, many products are being required to meet certain flame retardant criteria both by local and federal government and the manufacturers of such products. One particular set of conditions employed as a measuring standard for flame retardancy is set forth in Underwriters' Laboratories, Inc. Subject 94. This document sets forth certain conditions by which materials are rated.
In the art, there are many known flame retardant additives which are employed by mixing with products to render such materials flame retardant. Such flame retardant additives have been known to be employed in amounts of 5 to 20 weight percent in order to provide flame retardant characteristics to those products which are combustible.
Aromatic carbonate polymer compounds (polyarylenecarbonates), polyarylsulfones, and polyarylethersulfones, in admixture with themselves, or when blended with acrylonitrile-butadiene-styrene copolymer (ABS), do not exhibit adequate flame retardancy to meet Underwriters' Laboratories Subject 94 ratings in certain thicknesses. As a result, various flame retardant additives have been disclosed in the art which render such compositions flame retardant, which are effective in varying degrees.
Furthermore, when used alone the aforementioned aromatic carbonate polymer compounds (polyarylenecarbonates) polyarylsulfones and polyarylethersulfones, while sometimes meeting the broad standard of
Underwriters' Laboratories Subject, nevertheless exhibit longer flame out times than when used in admixture with the compounds which are the subject of the present invention.
Summary of the invention
It has now been surprisingly discovered that polyarylsulfones, polyarylethersulfones and blends of two or more compounds selected from the group comprising polyarylenecarbonates, acrylonitrile-butadienestyrene copolymers, polyarylsulfones and polyarylethersulfones can be made flame retardant by incorporating with such compositions a minor amount of an organic sulfonate as a flame retardant additive.
The organic sulfonates useful as flame retardant additives in the present invention are of the general formulas RSO3-M+ and (RSO3-)2M'++ where M+ is an alkali metal ion, M'++ is an alkaline earth metal ion,and R is chosen from the group consisting of
where each X is independently chosen from the group consisting of fluorine, bromine, iodine, NO2 and
where X' is the same as X, and n=0-5, m=0-4.
The preferred flame retardant additives are compounds selected from the group comprising
and compounds of the formula
wherein X is Cl or Br and n is a number from 0 to 5 or blends thereof.
The amount of the additive employed herein can vary, preferably, from about 0.01 to about 10 parts per hundred parts of the composition. In one preferred embodiment, the amount of additive incorporated with the composition is 0.5 parts per hundred parts aromatic polycarbonate. In a second preferred embodiment, the amount of additive is 1.0 part per hundred parts. The compositions of this invention can also contain other flame retardant additives, pigments, dyes, fillers, stabilizers and the like. Additionally, drip retarding agents which can include, but are not limited to, fluorinated polyolefins, fibrous glass, siloxanes and mixtures thereof can also be incorporated in the composition. The compositions can be processed by normal thermoplastic techniques as known in the art, such as injection moulding, foam moulding, extrusion, blow molding and the like.
Description of the preferred embodiment
The following examples are set forth to illustrate more clearly the principle and practice of this invention to those skilled in the art. Unless otherwise specified, where parts or percents are mentioned, they are parts or percents by weight.
Example 1
One hundred parts of Union Carbide's polyarylsulfone UNDELe P-1700 and 1 part of a compound of
Formula I are mixed by dry tumbling.
The resulting mixture is then fed to an extruder operating at about 265 C, and the extrudate is comminuted into pellets. These pellets are then injection molded at about 300"C into test bars of about 5 inches by 1/2 inch by about 1;16 inch thick. Five test bars are subject to the test procedure set forth in Underwriters'
Laboratories, Inc. Subject UL-94, Burning Test for Classifying Materials. In accordance with this test procedure, materials so investigated are rated either V-0, V-l or V-2 based on the results of 5 specimens.The criteria for each rating per UL-94 is briefly as follows:
"94V-0": No single flaming combustion after removal of the igniting flame shall exceed 10 seconds and
none of the specimens shall drip flaming particles which ignite absorbent surgical cotton
placed 12" below the specimen. Total flame out time for all 5 specimens (10 ignitions) cannot
exceed 50 seconds.
"94 V-1": No single flame combustion after removal of the igniting flame shall exceed 30 seconds and
none of the specimens shall drip flaming particles which ignite absorbent surgical cotton
placed 12" below the specimen. Total flame out time for all 5 specimens (10 ignitions) cannot
exceed 250 seconds.
"94-V-2": No single flaming combustion after removal of the igniting flame shall exceed 30 seconds. The
specimens drip flaming particles which burn only briefly, some of which ignite absorbent
surgical cotton placed 12" below the specimen. Total flame out time for all 5 specimens (10
ignitions) cannot exceed 250 seconds.
In addition, a test bar which continues to burn for more than 30 seconds after removal of the igniting flame is classified, not by UL-94, but by standards of the instant invention, as "burns". Further, UL-94 requires that all test bars in each test group must meet the V type rating to achieve the particular classification. Otherwise, the 5 bars receive the rating of the worst single bar. For example, if one bar is classified as 94 V-2 and the other four are classified as 94 V-0, then the rating for all 5 bars is 94 V-2.
