A wood-grain wallpaper made from wood-plastic waste and its preparation method

Abstract

The invention discloses wood-grain wallpaper made of wood-plastic garbage. The wood-grain wallpaper comprises the following components in percentage by weight: 40-68% of polyvinyl chloride (PVC) particles, 18-30% of modified wood flour, 10-16% of long fibers, 10-15% of modified stone powder, 3-6% of spar, and the balance of glue, wherein the PVC particles are recycled plastic, the modified wood flour is recycled wood chips, the long fibers are straw, the modified stone powder is recovered concrete garbage, and the spar material is recycled colorful pebbles or glass. The invention further provides a preparation method of the wood-grain wallpaper prepared from the wood plastic-garbage. The preparation method comprises the following steps: 1) removing organic matter; 2) carrying out modification treatment; 3) carrying out filament formation on the long fibers; 4) grinding the spar; 5) carrying out pulp mixing; 6) preparing a single-layer thin film; and 7) preparing the wallpaper. The invention provides a wide eliminating platform for various types of garbage which mainly contains white-pollution garbage, and the wallpaper with tree-dimensional impression and rich color and texture isobtained and is an advanced product taking wood-plastic garbage as a raw material. Meanwhile, the wallpaper is simply to lay and is high in laying quality, and edges do not warp easily.

Description

technical field [0001] The invention relates to the technical field of wood-plastic materials, in particular to a wood-grain wallpaper made from wood-plastic waste and a preparation method thereof. Background technique [0002] Wood-plastic, that is, wood-plastic composites (Wood-Plastic Composites, WPC), is a new type of composite material, which refers to the use of polyethylene, polypropylene and polyvinyl chloride instead of the usual resin adhesive, with more than 35% -70 More than 100% wood flour, rice husk, straw and other waste plant fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce boards or profiles. Mainly used in building materials, furniture, logistics packaging and other industries. [0003] Among them, PVC wood-plastic products can use new materials or recycled garbage as raw materials, and are easy to modify, thus providing a very good platform for wood-pla...

Problems solved by technology

In fact, PVC wallpaper has better three-dimensional appearance and environmental performance. It is a high-end wallpaper product. However, in the field of wallpaper or curtains, PVC wood-plastic waste is rarely used. The reason is that PVC wallpaper does not use PVC as the base material. , so the capacity to absorb white polluting waste is limited

[0004] Patent CN 106671556 A proposes "a preparation method of high-performance wallpaper", which uses PVC artificial leather prepared from PVC slurry as the base material, which greatly improves the ability to absorb white polluted garbage; but at the same time, due to the thicker base material High, it is difficult to lay, and it is easy to edge up on the wall, so it is not suitable for large-scale applications
