Embodiment Construction
[0023]The present disclosure provides for a composition of matter and methods to produce sustainable elastomer composite materials using algae as a bio-based filler. Algae biomass and components of algae can be derived from both a microalgae and a macroalgae. Algae biomass includes but is not limited to biomass produced by algae species. Example algae species include, but are not limited to, Haptophyta, Cyanophyta, Chlorophyta, Ochrophyta, Rhodophyta, and Phaeophyta, for example blue-green algae, green algae, diatoms, red algae, and brown algae.
[0024]In one form, the algae biomass includes a composition of protein from about 1% to 60%, ash from about 1% to 90%, carbohydrates from about 1 to 50%, and lipids from about 1% to 30%. The algae biomass may be washed or fractionated to achieve better compositions for rubber incorporation, or they may be harvested with a composition which is well suited for elastomer incorporation. Due to interactions between protein and sulfur based curing ...

Abstract
An algae-elastomer composite including an elastomer matrix; algae; and a mixing additive sufficient to achieve a desired property. The algae can be present in a milled condition having a particle size value of between about 10 and 120 microns. The algae is mixed with the elastomer matrix in a dry condition having a moisture content of below about 10%. A method of preparing the algae-based elastomer composite is provided that includes the steps of: premixing an elastomer matrix; adding an algae filler; adding a mixing additive that includes a plasticizer; forming an elastomer-algae blend by blending the algae and elastomer to a temperature sufficient to be further mixed, wherein the temperature is about 10° C. higher than the temperature sufficient for the elastomer alone; adding and mixing a curing or vulcanizing agent for the elastomer dispersing the elastomer-algae blend; and heating and curing the elastomer-algae blend into a final form.
Description
CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of U.S. Provisional Patent Application No. 62 / 663,893, titled “ELASTOMER COMPOSITE INCLUDING ALGAE BIOMASS FILLER,” and filed on Apr. 27, 2018, the disclosure of which is incorporated herein by reference in its entirety for all purposes.TECHNICAL FIELD[0002]The present disclosure relates generally to the field of elastomers and elastomer composite production using biomass.DESCRIPTION OF RELATED ART[0003]Rubber and elastomer composites are often desired for consumer goods, particularly for footwear, anti-fatigue mats, gasketing, insulation, sporting goods, automotive parts, and other related industries. An elastomer composite includes a filler material that may modify the elastomer to result in desired mechanical, thermal and other physical properties such as hardness, durability, strength, resilience, temperature stability, and the like. Moreover, there is an environmental incentive to id...
