A composite epoxy resin board, made from a raw material which includes the following weight percentage of components: waste prepreg powders of 5% to 100%, and waste printed circuit board (PCB) powders of 0% to 95%, is disclosed. The present invention adopts the waste prepregs as the main preparation raw material, which not only recycles and reuses prepreg scraps, but also reduces or even eliminates the use of adhesives due to the high epoxy resin content in the prepregs, while also reducing the glue-mixing time in the forming process, thereby simplifying the forming technology.

A method of manufacturing a building panel with a decorative surface layer, a core and a balancing and/or protective layer, wherein the method includes applying a first layer of a first powder based mix, including wood fibers and a thermosetting binder, on a core; applying a liquid substance on the first powder based mix; drying the first powder based mix; turning the core with the dried first powder based mix such that the first powder based mix points downwards; applying a second layer on the upper part of the core; and curing the first and second layers by providing heat and pressure, wherein the first layer forms the balancing and/or protective layer and the second layer forms the decorative surface layer in the building panel.

A method for manufacturing a breathable hybrid leather includes: a raw material supply step of supplying the natural leather of recycled leather; a step of applying a hot-melt adhesive to the upper surface of the leather raw material; a bonding step of supplying a fabric to the upper surface of the adhesive layer and applying heat and pressure to the leather raw material, the adhesive layer, and the fabric to obtain a bonded fabric; and a step of ironing and coating the bonded fabric a plurality of times.

A method for laminating profile and plate materials produced from processed mixed plastic waste and other plastic surfaces comprises steps of collecting and processing of mixed plastic waste for recycling for making profile and plate materials and lamination of profile and plate materials produced from processed mixed plastic waste, wherein the lamination of profile and plate materials produced from processed mixed plastic waste comprises stabilizing the profile temperature before lamination; determining the surface quality; making the surface quality of profile suitable by propane gas treatment of the profile; heating the profile surface before the lamination process; heating the adhesive right before the lamination; applying the adhesive to the laminate surface; carrying out the lamination process; and directing the laminated profiles for storying.

The present invention is related to decorative multi-layer surface coverings comprising a core layer, wherein said core layer comprises a polymer blend, said polymer blend comprising polyvinyl butyral and polylactic acid.

A process and system for making a laminated surface covering and the surface covering itself are described. The covering includes several layers bonded to each other. The system performs the process. One example of the process includes passing a first material across a first conveyor, passing a second material across a second conveyor, passing a bonding material across a third conveyor, contacting the first material and the second material to the bonding material, and heating at least one of the first material and the second material. The process also includes introducing the first material, the second material, and the bonding material into a pressure zone such that the bonding material is introduced between a bottom surface of the first material and a top surface of the second material. The process applies pressure to bond the first material and second material together via the bonding material to produce a laminated material.

An object of the present invention is to provide a multilayer container in which yellowing of a regenerated polyester resin at the time of recycle is suppressed and a method for producing the same as well as a method for producing a single-layer container. Furthermore, another object of the present invention is to provide a method for producing a regenerated polyester resin from the foregoing multilayer container and single-layer container. The multilayer container of the present invention includes at least one polyester resin composition layer containing a polyester resin (X) and an amino group-containing compound (A) having a yellowing-suppressing ability; and at least one polyamide resin layer containing a polyamide resin (Y).

This disclosure concerns paper-based packaging films having a structure including a paper component, a 2 to 10 micron thick polymeric film coated with a barrier material, and a patterned scalable material.
