BUFFING DUST WASTE/POLYSTYRENE THERMAL INSULATOR

The buffing dust waste/polystyrene thermal insulator is a polymer composite containing 0.1%-25% by weight buffing dust waste from a leather tannery, the balance being polystyrene. The composite has extremely low thermal conductivity (e.g., 0.0447 W/m-K for a composite 10% budding dust by weight), making it a good insulator, while still having relatively high mechanical properties. The thermal insulator is made by mixing the buffing dust with the polystyrene polymer in a twin-screw extruder and pouring the mixture into a steel mold. The mold is heated and compressed in a hot press machine, e.g., at 500 kg force at 180 C. for 20 minutes, which may be followed by 500 kg force at 125 C. for an additional 20 minutes. The resulting composite polymer is suitable for use as thermal insulation in buildings.

Method of bonding a thermoplastic component to a carpeted component

A method of bonding a thermoplastic component to a carpeted component is provided. The method includes providing a base component, a thermoplastic component and a fibrous carpet or mat between the components. The carpet has a large number of cavities. The carpet is made of a thermoplastic material adapted to bond to the thermoplastic component in response to heat at the interface between the thermoplastic component and the carpet. The method also includes heating the thermoplastic component and the carpet at the interface between the thermoplastic component and the carpet for a period of time to soften the carpet. The method finally includes pressing the components and the softened carpet together under a pressure to cause the softened carpet to flow and at least partially fill the cavities. The carpet at the interface is transformed into a solid bonding layer to bond the components together to create a finished structure.

Artificial botanicals and methods of making same
11872727 · 2024-01-16 ·

An artificial flower, plant, or other botanical is produced from an aqueous agar-based solidifying mixture. The artificial botanical may be colored as desired by adding one or more colorants. The artificial botanical may also be scented by adding a perfume, odorant, or other scent. Because the artificial botanical is produced using the aqueous agar-based solidifying mixture, no animal-based gelatin products are used. The artificial botanical may thus also be edible and satisfies vegan diets. The artificial botanical may thus also be flavored by adding a flavoring, such as fruit, concentrate, or sweetener. The artificial botanical may be all-natural and edible by adding mica powder as the colorant and by adding glycerin as the flavoring.
