Elastomer modified plastic-wood composite board and preparation method thereof

Abstract

The invention relates to a plastic-wood material, particularly to an elastomer modified plastic-wood composite board and a preparation method thereof. Plastic particles, maleic anhydride grafted plastic particles, kaolin powder, hollow glass microspheres and stearic acid are placed in a mechanical stirring kettle to be stirred and then are extruded and granulated, so as to obtain modified plastic particles; and the modified plastic particles, wood powder, a polyolefin elastomer, a thermoplastic polyurethane elastomer and pigment are placed into the mechanical stirred kettle to be stirred and uniformly mixed, then are melted, blended and extrusion-molded and finally pass through a flat finish mold, so as to obtain the elastomer modified plastic-wood composite board. The elastomer modified plastic-wood composite board provided by the invention has the advantages as follows: the production-manufacturing is convenient, the degree of mechanization of the production process is higher, less labor is required, and the production cost is low; the consumption of plastics is low, environmental friendliness and creep deformation resistance are achieved, the strength and the rigidity are high, and the service life is longer; and the elastomer modified plastic-wood composite board can be widely applied to various fields such as transportation, decoration, municipal gardens and packaging.

Description

technical field [0001] The invention relates to a plastic-wood composite material, in particular to an elastomer-modified plastic-wood composite material plate and a preparation method thereof. Background technique [0002] Wood-plastic composite material is a new type of structural material with great market potential. One of its main raw materials, wood powder or bran powder, is a large amount of agricultural and forestry crop leftovers, and the polymer material compounded with it is usually an industrial material with a wide range of uses. Therefore, the main raw materials of wood-plastic composite materials are cheap, and a new type of composite material can be produced by bonding these two cheap and abundant materials together. Wood-plastic composite materials can not only be recycled, but also can overcome the limitations of wood such as anisotropy, low strength, and large variability. Quantity and other usage defects. Therefore, plastic-wood composite materials ca...

Problems solved by technology

However, due to the relatively high addition of plant fiber powder and other inorganic fillers in the preparation of wood-plastic composite materials, there are some obvious deficiencies in the performance of wood-plastic composite materials, such as low static bending strength and high brittleness. It is fragile due to impact, especially at the corners of the edges, which affects its use effect, shortens its service life, and limits its use range
