Injection molding material containing starch and plant protein

An injection molding material that includes a renewable resin containing a combination of renewable polymers (e.g., starch and plant protein) and a plasticizer is provided. Although such compounds are normally difficult to process into thermoplastics, the present inventors have discovered that injection molding materials may nevertheless be formed by melt blending the renewable resin with a synthetic resin (e.g., polyolefin) while selectively controlling the nature of the resins and their relative concentrations. In this manner, a morphology may be achieved in which the renewable resin is present as a discontinuous phase that is dispersed within a continuous phase of the synthetic resin (e.g., “island-in-the-sea” morphology). The discontinuous and continuous phases may each constitute from about 30 vol. % to about 70 vol. %, and in some embodiments, from about 40 vol. % to about 60 vol. %. With such a morphology, the continuity of the synthetic resin can minimize the aggregate properties of the renewable resin such that the molding material possesses melt properties similar to that of the synthetic resin. Further, this morphology may also minimize the need to use different molding tools as the shrinkage properties of the overall composition may be substantially similar to that of the synthetic resin.

Highly insulative cementitious matrices and methods for their manufacture

Insulation barriers incorporating a cementitious structural matrix formed from a cementitious mixture including a hydraulic cement and water. The insulation barriers are manufactured from cementitious materials in order to be lightweight, insulative, less expensive, and more environmentally compatible than those currently used; they may augment, and even take the place of, traditional insulation materials including insulations made of glass fibers, polyurethane foam, urea-formaldehyde foam, polystyrene, wood fiber, cellulose fiber, rock-wool, etc. The cementitious structural matrix of the insulation barriers usually includes a hydraulic cement paste (formed from the reaction of water with, e.g., a portland-type cement) in combination with a rheology-modifying agent, such as methylhydroxyethylcellulose, and a lightweight aggregate material, which lowers the density of the insulation barrier and increases its insulation ability. Fibrous materials may be incorporated into the cementitious mixture to increase the strength of the final product, while a discontinuous phase of nonagglomerated voids may be incorporated into the cementitious structural matrix to decrease the density and increase the insulation ability of the final product.

Hydraulically settable containers and other articles for storing, dispensing, and packaging food or beverages

Containers incorporating a hydraulically settable structural matrix including a hydraulically settable binder such as cement for use in the storing, dispensing, and/or packaging of food and beverage products are disclosed. The disposable and nondisposable food and beverage articles of manufacture have high tensile, compressive, and flexural strengths, and are lightweight, insulative (if desired), inexpensive, and more environmentally compatible than those currently used. These disposable containers and cups are particularly useful for dispensing hot and cold food and beverages in the fast food restaurant environment. The structural matrix of the food and beverage containers includes a hydraulic cement paste (formed from the reaction of water with, e.g., a portland-type cement) preferably in combination with a rheology-modifying plasticizer, such as methylhydroxyethylcellulose, various aggregate materials, and fibrous materials, which provide desired properties at a cost which is economical.

Methods for the extrusion of novel, highly plastic and moldable hydraulically settable compositions

Hydraulically settable mixtures and methods for extruding such mixtures into a variety of objects which are form-stable in the green state. High green strength is achieved by increasing the yield stress of the mixture while maintaining adequate extrudability. Optimizing the particle packing density while including a deficiency of water yields a hydraulically settable mixture which will flow under pressures typically associated with the extrusion of clay or plastic. In addition, a rheology-modifying agent can be added to increase the yield stress of the mixture while not significantly increasing the viscosity. The desired strength properties and other performance criteria of the final hardened extruded product are controlled by adding aggregates, fibers, a hydraulically settable binder, water, and other admixtures.

Methods for manufacturing articles of manufacture from hydraulically settable sheets

Suitable compositions are prepared by mixing together a hydraulic binder, water, and appropriate additives (such as aggregates, fibers, and rheology-modifying agents) which impart predetermined properties so that a sheet formed therefrom has the desired performance criteria. Hydraulically settable sheets are formed from the mixture by extrusion, then calendering the sheets using a set of rollers and then drying the sheets in an accelerated manner to substantially harden the sheets. The resulting hydraulically settable sheets may have properties substantially similar to sheets made from presently used materials like paper, cardboard, polystyrene, or plastic. The sheets can be laminated, corrugated, coated, printed on, scored, perforated, cut, folded, rolled, spiral wound, molded, assembled and seamed to mass produce articles of manufacture from the sheets such as food and beverage containers.

Thermoplastically processable starch and a method of making it

In order to produce thermoplastically processable starch, an additive or plasticizer respectively is mixed with native or natural starch and the mixture is caused to melt by the application of heat and mechanical energy. The additive is a substance which lowers the melting point of the starch so that the melting point of the starch together with this additive lies below the decomposition temperature of the starch and the additive furthermore has a solubility parameter of over 15 cal 1/2 cm -3/2 . After the mixture of starch and additive is molten, the melt is mixed until it is at least almost homogeneous. The vapor pressure of the additive within the melting range of the mixture of starch and additive should be less than one bar. Preferably the mixing process is executed without the presence of water.

The hydrophobic polymer is in this connection at least substantially biologically degradable and thermoplastically processable and the mixture with the starch comprising a polymer phase mediator or a macromolecular dispersing agent so that the starch is present in the mixture as disperse phase with the hydrophobic polymer as continuous phase, and the phase mediator or the dispersing agent is responsible for the molecular coupling of the two phases. As starch there is preferably used thermoplastic starch which has been prepared substantially with the exclusion of water by means of sorbitol or glycerol. The production of the biologically degradable polymer mixture is also carried out substantially with the exclusion of water.
