Description
Technical field
The utility model relates to a kind of composite board, and especially a kind of stalk composite board belongs to the material technology field.
Background technology
Therefore not only environmental protection but also energy-conservation of the reasonable utilization of stalk is subjected to extensive concern.Retrieval as can be known, application number is that 03212871.1 Chinese utility model patent discloses a kind of stalk decorative panel, is made of the mutual cross arrangement of adjacent two layers stalk layer the multilayer stalk layer, every layer of stalk layer is adhesive layer between the stalk layer by rectangular bar shaped stalk bonding formation side by side mutually.Add man-hour, earlier stalk is processed into slice, it is bonding to adopt special glue to carry out according to the neat back of project organization pendulum, utilizes hydraulic press that overall structure is compressed at last and the typing of heating.With its polishing, leaching paint is finished product at last.In addition, application number is that 200910182040.1 Chinese utility model patent discloses a kind of stalk plate, is raw material with straw and the resinae adhesive that is processed into certain size and shape, makes multi-purpose stalk plate.Though above-mentioned prior art has its advantage, do not take full advantage of stalk natural fiber intensity, fail to maximize the function of performance stalk, and when actual fabrication, mainly rely on bonding, need expend a large amount of binding agents, both be unfavorable for reducing cost, also cause secondary pollution easily.
Summary of the invention
The purpose of this utility model is: at the shortcoming of above-mentioned prior art existence, proposing intensity under a kind of equivalent weight situation significantly improves and can significantly reduce the stalk composite board that uses binding agent, provide its preparation method simultaneously, thereby stalk can be used more effectively.
In order to reach above purpose, stalk composite board of the present utility model comprises upper and lower cladding boards, accompany stalk layer between the described upper and lower cladding boards, it is characterized in that: described stalk layer by perpendicular to cladding boards and the isometric stalk section that bears against mutually together constitute, the upper/lower terminal of described stalk section is adhesively fixed by binding agent and cladding boards respectively.
Stalk composite board of the present utility model has kept the original structure of fibrous tissue of stalk, in fact formed the stalk layer of honeycomb, therefore can give full play to the effect of stalk self, under the equivalent weight situation, make composite plate have maximum intensity and rigidity, have the high-strength remarkable advantage of light weight, and the hollow structure of stalk self makes also composite plate of the present utility model have very excellent insulating, soundproof effect.
One of stalk composite board preparation method of the present utility model may further comprise the steps:
The first step, customized cut-off---with stalk along its length customized cut-off be stalk section (can adopt no pressure cutting means such as sawing, laser cutting during cut-out, keep stalk not by pressure break);
Second step, gather and manage---the stalk section of fixed length is gathered managed, form upper and lower surface and upper and lower cladding boards corresponding stalk layer (when needs are gained in strength by the raising packing, can be when gathering periphery apply bigger extruding force) respectively;
The 3rd goes on foot, is coated with glue bond---and behind difference coated with adhesive between the upper and lower surface of stalk layer and the upper and lower cladding boards, positioning bonding is fixed;
The 4th step, curing molding---after the to be bonded dose of curing, both obtained required stalk composite board.
The utility model is further one of perfect to be, the upper/lower terminal of described stalk section has backfin face respectively, and described backfin face is adhesively fixed by binding agent and cladding boards.Accordingly, in second step of method one, stalk section gather manage after, frame is in height is framed less than first rigidity of stalk section length, pressurization makes the end bending of stalk section, forms an end backfin face; Behind the turn-over, in height second rigidity framed less than first rigidity was framed, pressurization made the other end bending of stalk section, forms other end backfin face with its frame again.Like this, in follow-up adhesion step, stalk section and cladding boards are bondd more fully.
The utility model further perfect two is, described cladding boards periphery is fixing to be enclosed in wherein edge sealing frame with stalk layer, by adhesive bond, described cladding boards and banded plate are fire proofing, add fire retardant in the described binding agent between described edge sealing frame and the stalk layer.So not only make composite plate of the present utility model have better overall, but also can effectively suppress the inflammability of stalk.
Two of stalk composite board preparation method of the present utility model may further comprise the steps:
The first step, gather and manage---stalk is gathered managed, be placed in the U-shaped frame of cross section and edge sealing frame consistent size, sealed open limit after the compacting forms sealing post (when needs are gained in strength by improving packing, can apply bigger extruding force from opening part when gathering);
Second step, customized cut-off---by required thickness of slab will seal post together with wherein stalk along its length customized cut-off (can adopt no pressure cutting means such as sawing, laser cutting during cut-out, keep stalk not by pressure break), form the stalk layer that is enclosed in the edge sealing frame;
The 3rd goes on foot, is coated with glue bond---and behind difference coated with adhesive between the upper and lower surface of the stalk layer behind the customized cut-off and the upper and lower cladding boards, positioning bonding is fixed;
The 4th step, curing molding---after the to be bonded dose of curing, both obtained required stalk composite board.
