Description

A kind of imitation wood stricture of vagina co-extrusion Wood-plastic material and processing method thereof
Technical field
The present invention relates to a kind of composite and processing method, be specifically related to a kind of imitation wood stricture of vagina co-extrusion wood plastic composite with microporous foam effect and processing method, belong to technical field of composite preparation.
Background technology
Wood plastic composite (WPC) is the class advanced composite material (ACM) being in recent years surging forward both at home and abroad, refer to utilize polyethylene (PE), polypropylene (PP) and polrvinyl chloride (PVC) etc., replace common resin adhesive, it is mixed into new wood materials with useless Plant fiber such as the wood powder more than more than 50%, rice husk, straw, Caulis et Folium Lini, cotton stalks, again through the plastic processings such as extruding, mold pressing, injection moulding, the sheet material produced or section bar.Compared with traditional wood materials, it has attractive in appearance, water-fast, Anti-moth-eating, the advantage such as corrosion-resistant, the most easy to crack, is widely used in making timber substitute products.At present, wood plastic composite on market, appearance tactile impression is single mostly, for realizing the woodiness touch on surface, mostly take with corundum or the bright layer of wire brush polishing surface skining, or use the Metal Contact Rollers heated again, roller surface is carved with the modes such as imitation wood stricture of vagina rolling Wood-plastic material surface, thus realizes the imitation wood effect on the surface of Wood-plastic material.But mostly the method used is mechanical means, surface of wood-plastic composite material will polish off or brush off a thin layer, form the longitudinal lines being similar to coarse board surface, gained lines is unnatural, true to nature.
It addition, the crack tip in common WPC, Anticrack, thus can overcome that normal wood plastic composite materials fragility is relatively big, impact strength is less and material percentage elongation is relatively low.Containing a large amount of abscesses in microporous foam wood plastic composite, material internal space is bigger, during preparation, amount of resin used is cut down significantly, reduce environmental pollution, relatively save cost of material, also (the 50% of the most unexpanded wood plastic composite, up to 0.6-1g/cm to effectively reduce the density of material3), the sound insulation of material, heat insulation and buffering effect improve the most therewith.
Therefore, if two problems are solved simultaneously, range and value that wood is moulded can not only be expanded, it is also possible to alleviate environmental problem, there is higher environmental benefit and economic benefit.
Summary of the invention
The invention provides a kind of imitative wood grain effect a kind of microporous foam imitation wood stricture of vagina co-extrusion Wood-plastic material true to nature and processing method thereof.Process technology production technology moulded by the imitation wood stricture of vagina wood of comprehensive Wood-plastic foam plate processing sum.
