An earth plant-based compostable biodegradable composition for the formation of a bioplastic and method of producing said resin, the composition comprising: about 17.5 to 45% ethanol-based green polyethylene by weight, about 20 to 25% calcium carbonate by weight, about 2 to 12% hemp hurd or soy protein by weight, about 32 to 45% starch by weight, and about 0.5 to 1% biodegradation additive by weight to enable biodegradation and composting of the bioplastic; wherein the composition is produced by first mill grinding the ethanol-based green polyethylene, calcium carbonate, hemp hurd or soy protein, starch and the biodegradation additive into fine powders, then mechanically mixing the fine powders one by one into a final mixture for about 5-25 minutes at a time, dry and without heat, and then heating the final mixture to about 220 to 430 degrees Fahrenheit.

A method of manufacturing includes producing a powder resin comprising a polymer precursor and a thermal initiator, packing a fiber structure with the powder resin, resulting in a resin-packed structure, and heating the resin-packed structure to a curing temperature high enough to melt and cure the resin-packed structure to form a final structure.

A method for producing a sealant includes a weighing and mixing step, a kneading step, a stirring and defoaming step, and a filling step. In the weighing and mixing step, a main component and a curing agent are weighed and mixed together. In the kneading step, the mixture mixed in the weighing and mixing step is kneaded. In the stirring and defoaming step, the kneaded product kneaded in the kneading step is stirred and defoamed. In the filling step, the kneaded product defoamed in the stirring and defoaming step is filled into a container. In the stirring and defoaming step, the kneaded product is stirred under a condition wherein a stirring rotational speed at which the kneaded product is stirred and a stirring time for which the kneaded product is stirred are within a range from an arithmetic product lower limit value to an arithmetic product upper limit value.

A composition of the present invention includes: a styrene-based elastomer; a paraffin-based process oil; an olefin resin; a crosslinking agent including an organic peroxide; a crosslinking aid; an antioxidant; and a surface-treated filler obtained by surface treating particles formed from magnesium hydroxide with a higher fatty acid. The paraffin-based process oil has a kinematic viscosity at 40° C. of 300 mm.sup.2/s or greater. Furthermore, from 405 to 485 parts by mass of the paraffin-based process oil, from 9 to 13 parts by mass of the olefin resin, from 5 to 7 parts by mass of the crosslinking agent, from 13 to 15 parts by mass of the crosslinking aid, from 3 to 4 parts by mass of the antioxidant, and from 15 to 25 parts by mass of the surface-treated filler are respectively blended per 100 parts by mass of the styrene-based elastomer.

A method for manufacturing a phosphor sheet is provided. In the method, a particulate phosphor and a particulate transparent medium are mixed to a first light transmissive resin in a liquid state. The first light transmissive resin containing the phosphor and the transparent medium in the liquid state is supplied into a lower mold of a mold, and the mold is closed. The first light transmissive resin containing the phosphor and the transparent medium in the liquid state is changed to a solid state having a predetermined thickness by applying a heat and a pressure to the first light transmissive resin containing the phosphor and the transparent medium in the liquid state.

The invention relates to an extrusion process for the production of expandable vinyl aromatic polymer granulate comprising mixing first and second additives with first and second polymer components, respectively, in dedicated mixers.

The invention to provide a system of equipment for making synthetic building materials using plastic wastes combined with industrial and agricultural scrap includes: sorting and cleaning equipment, grinding equipment, powder grinding equipment, mixing equipment, pelletizing equipment, drying equipment, hot stir equipment, shaping equipment are connected together by mechanical connectors. The database connected to the controller controls the sorting and cleaning equipment, the grinding equipment, the powder grinding equipment, the mixing equipment, the pelletizing equipment, the drying equipment, the hot stir equipment, and the shaping equipment through transmission channels. In addition, the present invention provides a method of manufacturing for making synthetic building materials using plastic wastes combined with industrial and agricultural scrap.

A method of forming a composite material includes mixing granules of thermoplastic(s) and granules of reinforcing material(s) using a mixer with an interior friction coating. The friction generated by interaction between the granules and friction coating causes granules of at least one of the thermoplastic(s) to be heated to a liquid or semi-liquid state. The liquid/semi-liquid thermoplastic(s) act a binder for the mixed material. A system for forming such a composite material includes such a mixer with an interior friction coating. The system may also include a mould and/or a press for forming material produced by the mixer into a finished shape. The method and system may use post-consumer and post-industrial material as an input allowing such material to be recycled. In some cases, cross-contaminated or mixed post-consumer/post-industrial material may be recycled, potentially reducing environmental impacts.
