Description
Technical field
This utility model belongs to composite board technical field, is specifically related to a kind of high-strength environment-friendly plywood.
Background technology
Plywood is to be peeled into veneer by juggle or become veneer by flitch slicing, then sticks with glue the three layers of agent gluing or the board-like material of multilamellar, typically by odd-level veneer, and makes the orthogonal gluing of machine direction of adjacent layer veneer form.Plywood is one of furniture common used material, for one of big plate of wood-based plate three, is also available for the effect materials such as aircraft, boats and ships, train, automobile, building and packing crates.One group of veneer generally forms by the orthogonal assembly gluing of adjacent layer grain direction, and generally its dash board and inner plating are symmetrically arranged at central core or the both sides of plate core.With the veneer after gluing by the crisscross slab being made into of grain direction, when heating or not heating, compacting forms.The number of plies is generally odd number, and minority also has even number.The physics in direction, engineering properties difference are less in length and breadth.Conventional plywood type has three-ply board, five-ply board etc..Plywood can improve timber utilization rate, is the main path saving timber.Common length and width specification is: 1220 × 2440mm, and thickness specification then generally has: 3,5,9,12,15,18mm etc..Chief species have: San Cheong, willow are pressed, poplar, Eucalyptus etc..
There is many defects in existing plywood: each layer of existing plywood is generally one piece of imposite, and this structure is unfavorable for making lengthy product, and firmness and the stability of plywood are not as；And existing plywood is essentially all and bonds with carpenter's glue, with the plywood of this glue bond not only intensity difference, not environmentally, and not moisture-proof, easily ftracture after water is invaded bubble.
Summary of the invention
The purpose of this utility model is for prior art Problems existing, it is proposed to a kind of firmness and stability is higher and the high-strength plywood of environmental protection, moisture-proof.
Technical solutions of the utility model are as follows: this utility model one high-strength environment-friendly plywood, including the panel layer being sequentially connected with from top to bottom, core layer and backplane level；Undertaken bonding by glue-line between described panel layer, core layer and backplane level；Described panel layer includes the interconnective panel unit of at least two；Described core layer includes the interconnective central layer unit of at least two；Described backplane level includes the interconnective bottom board unit of at least two；Described panel layer is provided with a TPU overlay film；Described backplane level is provided with the 2nd TPU overlay film；Between described panel layer and a TPU overlay film and bonding each through PVC glue-line between described backplane level and the 2nd TPU overlay film.
One end of panel unit described in the utility model, central layer unit and bottom board unit is equipped with connection bump, and the other end is equipped with connecting groove；It is connected each through connection bump and connecting groove between described panel unit, between described central layer unit and between described bottom board unit.Described glue-line is the urea-formaldehyde glue layer being added with pomelo peel powder.The thickness of described core layer is 8-13mm.The thickness of described panel layer and backplane level is 5-8mm.
The beneficial effects of the utility model: this utility model one high-strength environment-friendly plywood, every laminate is connected and composed by multiple Slab element, and the junction of adjacent panels unit staggers setting, and every laminate is connected by connection bump and connecting groove, on the one hand, improve the firmness of plywood, the good stability of plate, intensity is high；On the other hand, it is possible to make full use of material and more effectively make lengthy product, practical；This utility model one high-strength environment-friendly plywood, by adding pomelo peel powder in urea-formaldehyde glue, the burst size of methanal of plywood can be significantly reduced, because containing compositions such as substantial amounts of flavone, tannin in pomelo peel, can effectively remove formaldehyde free in urea-formaldehyde glue, and the bonding strength of plywood can be significantly improved；This utility model is provided with again TPU overlay film on panel and base plate so that overall structure has resistance to water and wearability, while increasing plywood sheet material service life, does not affect again the softness of plywood sheet material.
