Hydrocarbon-free, non-polymeric formulations and articles

a technology of non-polymer formulations and compositions, applied in the direction of fuels, waste based fuels, cement ingredients, etc., can solve the problems of avoiding the use of polymeric and traditional hydrocarbons, is particularly challenging, and none of these techniques alone, can meet all the required and above-described desirable characteristics, and achieve the effect of improving the processing and flame-burning characteristics of articles

Softening Point Improvement

[0066]An important characteristic of a fuel, whether or not combined with a fibrous material, is the ability to hold together the formed article in a cohesive unit that doesn't melt and flow off or slump into an unusable pile. This property is dependent upon more than just the melting point. A test method, the Ring and Ball Test, was used to determine the suitability of formulations in this regard.

[0067]The Ring and Ball Test measures strength as the melting point of the fuel is approached: a ¼ inch thick disc made up of the sample, e.g., a composite, must support a steel ball ⅜ of an inch in diameter and weighing 3.5 to 3.6 grams. This is a variation of other ring and ball softening point tests, such as ASTM D 36, and uses the same equipment. The sample disc is ⅝ of an inch in diameter in the bottom 0.1 inch of thickness, and ¾ of an inch in diameter in the top 0.15 inch of thickness, thus resting on a lip in the sample holder. The steel ball sits on top ...

Abstract

Disclosed herein are compositions comprising blends of at least one triglyceride; at least one fatty acid; and at least one fatty acid derivative, whereby said compositions exhibit improved processing and flame/burn characteristics. The compositions may, optionally, further comprise fillers, extenders, modifiers, binders, flame and article colorants, and perfumes and are useful in the manufacture of, for example, fireplace logs, fire starter blocks, candles, and the like.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of Invention[0002]The present invention relates to moldable and extrudable compositions that are useful for producing articles, such as candles and artificial firelogs. The compositions, which are flammable and combustible, comprise additives, e.g. oils, fats, and their derivatives, for improving processing and burn characteristics.[0003]2. Description of Related Art[0004]Fatty triglycerides and fatty acids derived from them by hydrolysis and removal of glycerin are known to be employed as fuels in candles, fire starter blocks, fireplace logs, and similar articles. They are mixed with polymeric and / or hydrocarbon (waxy-type) fuels or formulated into composites with various forms of fiber or other solid species, usually flammable materials.[0005]U.S. Pat. No. 3,297,419 discloses a synthetic fuel log produced from a flame-supporting material that is solid at room temperature. A filler or extender of a combustible type is combined with the flam...
