Problems solved by technology

There are few reports on the application of road signs processed from wood-plastic composite materials. The main reason is that ordinary wood-plastic composite materials have short service life and require regular maintenance or replacement, which increases cost investment; To cover the reflective film, an adhesive with high bonding strength must be used, otherwise the reflective film will easily bubble or peel off during use, which will affect the normal use of road signs

Abstract

The invention discloses a wood-plastic composite material for processing road signs and a preparation method thereof, relating 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 to 25 parts of plastic particles recycled from beverage bottles, 15 to 20 parts of wood flour, 5 to 10 parts of chlorinated polyethylene, 5 to 10 parts of polyvinyl alcohol resin, 4 to 8 parts of rubber powder, 4 to 8 parts of coconut chaff, 3 to 6 parts of polyoxyethylene, 3 to 6 parts of activated clay, 2 to 4 parts of macroporous adsorption resin, 2 to 4 parts of pigments, 1 to 2 parts of dodecyl trimethyl ammonium chloride, 1 to 2 parts of nano rubber powder, 1 to 2 parts of hydrogenated palm oil, 0.5 to 1 part of trimellitic anhydride, 0.5 to 1 part of nano aluminium oxide and 0.5 to 1 part of 2-imidazolidone. The wood-plastic composite material disclosed by the invention is specially used for processing and preparing the road signs, and is good in processing formability; and additionally, the prepared road signs not only can be closely adhered to reflective films, but also have excellent mechanical properties, wear resistance, impact resistance and freeze-thaw resistance.

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 road signs 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, and the nail-holding force i...
