Abstract
The invention relates to a high-strength special flakeboard. Plant fiber materials are subjected to mold pressing to form a corrugated structure, and the high-strength special flakeboard comprises an upper top (1) extending longitudinally, a lower bottom (2) extending longitudinally and a bevel part (3) connecting the upper top (1) and the lower bottom (2), wherein the ratio of the thickness of the upper top (1) and the lower bottom (2) to the thickness of the bevel part (3) is more than 1.0. The thickness of the bevel part of the flakeboard is smaller than the thickness of the upper top and the lower bottom, so that the density of the bevel part of the flakeboard is guaranteed to be consistent with that of the upper top and the lower bottom, the rupture strength of the bevel part is improved, and the pressive strength of the flakeboard is greatly improved.
Description
Technical field
The present invention relates to a kind of particieboard, relate in particular to a kind of abnormally-structured particieboard that forms with plant fiber molding.
Background technology
Particieboard anti-pressure ability of the prior art is lower, is the patent of invention of ZL99815410.5 as China Patent No., and its Granted publication day is on December 11st, 2002, discloses a kind of method of plate with ribbing and made plate made.Above-mentioned patent is to make the method for plate with ribbing with a kind of slab that also has wood materials or agronomic crop fibre or man-made fibre material and add binding agent, in the method, with the slab of above-mentioned material as for being shaped in the pressing mold and in the condition lower compression of heating pressurization and curing, above-mentioned pressing mold has a kind of structure that has two outskirts and two beveled region at least with ribbing, and, above-mentioned pressing mold closes and forms a pressing mold gap when closing, wherein, in the above-mentioned pressing mold gap at least two above-mentioned outskirt places less than the above-mentioned pressing mold gap at least two above-mentioned beveled region places.Have at least two outskirts that extend longitudinally and have first thickness by said method and the produced plate of mould; At least one extends longitudinally and has the beveled region of second thickness, and above-mentioned beveled region is between above-mentioned outskirt and adjacent with above-mentioned outskirt; The ratio of the first above-mentioned thickness and the second above-mentioned thickness is less than 1.0, and promptly the thickness of beveled region is greater than the thickness of outskirt.The technical problem that this structure mainly solves is to be pressed into when abnormally-structured at this prefabricated slab, and in the deformation process of slab, beveled region is broken easily.This plate belongs to slim plate, and thickness mainly is below 3.56mm, and its anti-stretch-draw intensity is relatively poor, therefore, just can produce above-mentioned defective.Though such scheme can be good at solving the problem of beveled region fracture, this solution is to exchange in the density of sacrificing beveled region to solve the beveled region fracture.Make the density of beveled region reduce, its rupture strength reduces greatly.Thus, adopt such scheme to make high-intensity special-shaped shaving board and just have big drawback, can't satisfy high-intensity requirement.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiency of above-mentioned prior art, the profiled flakeboards of a kind of high strength that provides, bearing strength height, environmental protection.
According to a kind of high-intensity special-shaped shaving board provided by the invention, be molded into corrugated structure by sponge, comprise extend longitudinally on push up, extend longitudinally go to the bottom and be connected the inclined plane part that pushes up and go to the bottom on described, the described ratio of top and described thickness of going to the bottom and the thickness of described inclined plane part of going up is greater than 1.0.
Also have following attached technical characterictic according to a kind of high-intensity special-shaped shaving board provided by the invention:
