Problems solved by technology

In order to improve the appearance quality of the currently used building exterior wall decorative panels, it is necessary to spray a layer of paint on its surface, or make it into a colored decorative panel, but it is easy to cause the paint to fall off, fade or fade after 10-15 years of use. The fading phenomenon of decorative panels seriously affects the appearance quality

Abstract

The invention discloses a wood-plastic composite material for machining a building external wall decorative plate and a preparation method thereof and relates to the technical field of wood-plastic composite materials. The wood-plastic composite material is prepared from the following raw materials in parts by weight: 20-25 parts of linear low density polyethylene, 10-15 parts of lignocellulose, 5-10 parts of polyvinyl alcohol resin, 5-10 parts of microcrystalline cellulose, 3-6 parts of polyethylene oxide, 2-3 parts of ultrafine polytetrafluoroethylene powder, 2-3 parts of cross-linked polyvinylpyrrolidone, 2-3 parts of a pigment, 1-2 parts of petroleum coke micro-powder, 1-2 parts of asbestos wool, 1-2 parts of nano glue powder, 1-2 parts of anionic polyacrylamide, 0.5-1 part of magnesium aluminosilicate and 0.5 to 1 part of sulfated castor oil. The wood-plastic composite material disclosed by the invention has a good molding property and is specially used for machining the building external wall decorative plate; and the decorative plate has excellent mechanical properties and also has good wearing resistance, impact resistance and freezing-thawing resistance so that the service life of the decorative plate is prolonged.

Description

[0001] Technical field: [0002] The invention relates to the technical field of wood-plastic composite materials, in particular to a wood-plastic composite material for processing building exterior wall decorative panels and a preparation method thereof. [0003] Background technique: [0004] Wood-plastic composite material is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene, polypropylene and polyvinyl chloride instead of the usual resin adhesive, and more than 50% of wood powder, rice husk, straw, etc. Waste plant fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce plates or profiles, which are mainly used in building materials, furniture, logistics packaging and other industries. [0005] Wood-plastic composite materials have similar processing properties to wood, can be sawed, nailed, and planed...
