Abstract
A high strength restructuring bamboo comprises bamboo ties and phenolic resin glue, wherein the inside of the bamboo ties is soaked with the phenolic resin glue, and the bamboo ties are glued tightly through the phenolic resin glue. The high strength restructuring bamboo achieves the main aims of improving sizing uniformity of a restructuring bamboo and strengthening glue strength of the restructuring bamboo.
Description
Technical field
The utility model belongs to bamboo wood and makes the field, is specially high-strength reorganization bamboo.
Background technology
The reorganization bamboo is a kind of bamboo wood to be reorganized and a kind of bamboo matter new material of glue molding in addition.Compare the reorganization bamboo with other bamboo matter section bar and have the utilization rate of bamboo height, characteristics such as added value height.Bamboo the making of recombinating mainly comprises operations such as bamboo Shu Jiagong, drying, impregnation, redrying, assembly and heat (cold) is molded.Reorganization bamboo heat (cold) molded pressure is higher, and general surface pressure is at 6-7MPa, and the thick bamboo silk of cure under pressure forming process bamboo bundle part can split because of the high pressure effect.Because the cure under pressure moulding is after bamboo bundle impregnation, redrying, to carry out, so the situation of adhesive can appear lacking in dehiscence part, the bamboo that causes recombinating gummed is inhomogeneous, and bonding strength descends.Take certain measure, improve reorganization bamboo uniformity of size application, the glue performance that improves the reorganization bamboo is significant.
The utility model content
The technical problem that the utility model solved is to provide high-strength reorganization bamboo, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
High-strength reorganization bamboo comprises bamboo bundle, phenolic resin glue, and said bamboo bundle includes phenolic resin glue through dipping method, closely glues together through phenolic resin glue between the said bamboo bundle.
Through improving bamboo bundle uniformity of size application, improve its bonding strength, prepare a kind of high-strength reorganization bamboo.Promptly in common reorganization bamboo produces, increase the extruding and kneading operation, promptly before redrying, carry out extruding and kneading to the bamboo bundle that soaked phenolic resin glue through a kind of special-purpose bamboo bundle extruding and kneading device and handle, squeeze pressure is greater than reorganization bamboo heat (cold) molded pressure.Through the extruding and kneading processing the intrafascicular thick bamboo silk of bamboo is split, because the intrafascicular synvaren of squeezing action bamboo flows to the starved position of splitting because of extruding, it is intrafascicular to make adhesive all be distributed in bamboo simultaneously.Because squeeze pressure is greater than heat (cold) molded pressure, so heat (cold) the phenomenon that thick bamboo silk splits can not occur when molded once more.Therefore, part starved phenomenon can not occur in the reorganization bamboo, whole reorganization bamboo is evenly glued together, and therefore bonding strength is improved.
The bamboo Preparation Method of a kind of high-strength reorganization may further comprise the steps:
The first step: bamboo bundle extruding and kneading machine design; This device structure mainly comprises ram cylinder, oil pipe, top board, lower platen, upper roll wheel, lower roll wheel, support, baffle plate, ram cylinder and leakage glue hole; The extruding and kneading machine is last pressure type, but the lower platen horizontal movement;
Second step: the bamboo bundle is dry: through artificial drying or air dry, make its moisture content reach 10-12% the bamboo bundle that processes;
The 3rd step: bamboo bundle applying glue: bamboo Shu Zhacheng bamboo is tied in, immerse that solid content is housed is about 30% phenolic resin glue glue groove, the ratio that glue and bamboo the are restrainted 1:5 impregnation that feeds intake; The bamboo tow is tied taking-up after the submergence fully, deliver to bamboo bundle extruding and kneading machine behind the glue 30s that dries in the air at once;
The 4th step: bamboo bundle extruding and kneading: after the bamboo bundle is sent into the hopper of extruding and kneading machine lower platen; The ram cylinder plunger is descending; The extruding and kneading machine is closed; Fully closed back left and right sides ram cylinder alternation, extruding and kneading machine lower platen motion by a small margin about on the lower roll wheel realizes the extruding of bamboo bundle and rubs; Because the extruding and kneading machine top board left and right directions that exists of upper roll wheel does not have relative motion; The intrafascicular unnecessary phenolic aldehyde adhesive of bamboo can be through leaking glue hole recycling in the extrusion process;
The 5th step: bamboo bundle redrying: the bamboo bundle behind the extruding and kneading is dried to moisture content under 70 ℃ of left and right sides temperature be 10-12%;
The 6th step: mat formation: the bamboo after the redrying is restrainted the blank of mating formation into certain specification along machine direction, notice that thickness direction is range upon range of, the width tiling;
The 7th step: curing molding: the blank that paves is sent into the moulding of hot press hot-press solidifying, or sends into forming room's curing molding behind the locked mode of colding pressing, preparation reorganization bamboo square bar or sheet material; No matter be hot pressing or cold pressing, pressure pressure during all less than extruding and kneading; Carry out the subdivision saw at last as required and separate processing and utilization.
Beneficial effect
The utility model is through increasing bamboo bundle extruding and kneading operation between bamboo bundle impregnation and redrying operation, the intrafascicular thick bamboo silk of bamboo is split behind impregnation, before the drying and make the position applying glue of splitting.Because squeeze pressure greater than briquetting pressure, the phenomenon that the bamboo silk splits can not occur in reorganization bamboo heat (cold) molded process again, therefore, has guaranteed the even applying glue of whole reorganization bamboo clappers base, has evenly glued together, thereby improved reorganization bamboo bonding strength.Detect through test, adopt this method can reorganization bamboo bonding strength be improved about 10%.
