Description
Technical field
The invention belongs to building material technical field, relate in particular to a kind of flame-retardant bamboo laminated board and manufacture method thereof.
Background technology
Laminated veneer lumber is a kind of a kind of composite that the vertical strong mechanical performance of timber is made that makes full use of, mainly as purposes such as building bearing beam or other building cladding materials.Be that big footpath level timber amount usable is fewer and feweri and the fast growing wood performance can not satisfy the structural material of the performance brilliance that develops on the basis of structural wood purposes in the world, the various members that are used to make wooden house are up-and-coming developing direction.China's timber resources is poor relatively, but bamboo timber resource is very abundant, and bamboo wood has growth cycle short, the advantage that renewable is strong, develop bamboo timber resource energetically and be used in fields such as building, packing, furniture, finishing, realize the reasonable resources configuration and optimized use, met the sustainable development of ecological environment.
Simultaneously, timber and bamboo wood are as the important materials of main building structural materials and interior decoration decoration, and they all are natural wooden fiber's materials, belong to combustible material, in case fire takes place to bring huge disaster.In order to reduce their potential fire threats, flame treatment is a necessary step.Country is the people's safety and the property fire-retardant rules of having considered special setting, and carrying out fire-retardant to material all is very important key subjects in state in the people.
Summary of the invention
The purpose of this invention is to provide a kind of flame-retardant bamboo laminated board and manufacture method thereof, it is to utilize wooden recyclable materials---a kind of structure laminated timber that bamboo wood is made after flame treatment with certain fire resistance, the bamboo laminated board that this manufacture method makes is as architecture beam or other member, in use as when running into fire condition, can provide the long safe escape time.
For achieving the above object, the present invention takes following design:
A kind of flame-retardant bamboo laminated board manufacture method, its manufacture method step is as follows:
1) bamboo wood is analysed into thin bamboo strips used for weaving;
2) heat 15～60min in the retardant solution with 60～90 ℃ of thin bamboo strips used for weaving immersions;
3) pull out and put into rapidly in the identical normal temperature retardant solution, cooling 10～60min;
4) be dried to moisture content below 8% after draining;
5) thin bamboo strips used for weaving that contains fire retardant after the drying is immersed in the adhesive soak 5～60min;
6) drain, be dried to moisture content 8～15%;
7) hot pressing is sent into the thin bamboo strips used for weaving assembly in the hot press, 100～200 ℃ of hot pressing temperatures, and hot pressing time 0.1～1.5min/mm, hot pressing pressure 1.0～6.0Mpa becomes laminated timber with the bamboo wood thermocompression forming;
8) cold pressing, the laminated timber that takes out in the hot press is sent in the cold press, 10～60 ℃ of the temperature of colding pressing, the pressure 1.0～5.0MPa that colds pressing, time 10～150s/mm colds pressing;
9) cutting edge, saw are separated processing, and finished product is collected.
Contained component and percentage by weight thereof are for being in the described retardant solution:
1) APP 5～20%, boric acid or borax 0～5%, and diammonium hydrogen phosphate 0～5%, guanyl-urea-phosphate 0～10%, surplus is a water.
Also:
2) APP 0～15%, boric acid or borax 2～10%, and diammonium hydrogen phosphate 0～5%, guanyl-urea-phosphate 0～10%, surplus is a water.
3) APP 0～15%, boric acid or borax 0～5%, and diammonium hydrogen phosphate 1～10%, guanyl-urea-phosphate 0～10%, surplus is a water.
4) APP 0～15%, boric acid or borax 0～5%, and diammonium hydrogen phosphate 0～5%, guanyl-urea-phosphate 1～15%, surplus is a water.
Other have the chemical reagent of synergistic also can to add 0.5～1.0% pentaerythrite, melamine etc. in above-mentioned fire retardant.
The modified phenolic adhesive that described adhesive often adopts modification to handle, adhesive contains 25～40% admittedly; Also can adopt melamine resin, adhesive contains 25～50% admittedly.
A kind of flame-retardant bamboo laminated board, it is the bamboo laminated board that is made by above-mentioned manufacture method.
Advantage of the present invention is: physics, good mechanical properties, it can not only reach building structure wood property energy, and after the flame retarding process processing, its the highest exothermic peak, average rate of heat release, total heat burst size, weight loss rate all hang down 1/3 at least than the bamboo material stacked material without flame treatment, burning time prolongs 2/3, can reach difficult combustion construction material rank B1 level.
The specific embodiment
The implementation method of technical solution of the present invention is that bamboo wood (is meant that heating is exactly " heat channel " in the pyrosol in container by fire retardant treatment process with " cold and hot groove " method, put into rapidly normal temperature or more the low temperature container be exactly " cold trap ", be referred to as " cold and hot groove " method through processing procedure by " heat channel " to " cold trap ") immerse and contain phosphorus, nitrogen, the fire retardant of elements such as boron, and utilize bamboo wood longitudinally the high strength lamination make product, the flame-retardant bamboo laminated board that adopts the inventive method to make, can be widely used in building element, packing waits the material field, is a kind of comparatively desirable flame-retardant shaped bamboo material.
The specific embodiment of the invention is: a, bamboo wood is analysed into thin bamboo strips used for weaving, the thin bamboo strips used for weaving dimensional requirement is wide 1.5～3.0cm, thick 0.8～1.2cm; B, thin bamboo strips used for weaving immersed in 60～90 ℃ of retardant solutions heat 15～60min, pull out to put into rapidly in the identical normal temperature retardant solution and cool off 10～60min, be dried to moisture content below 8% after draining; C, the thin bamboo strips used for weaving that contains fire retardant after the drying immersed in the adhesive soak 5～60min, again through draining, being dried to moisture content 8～15%; D, by setting density the thin bamboo strips used for weaving assembly is sent in the hot press, (hot pressing pressure 1.0～6.0Mpa) is with bamboo wood slab thermocompression forming for 100～200 ℃ of hot pressing temperatures, hot pressing time 0.1～1.5min/mm according to certain hot compression parameters; E, take out the hot pressing laminated timber and send in the cold press, 10～60 ℃ of the temperature of colding pressing, the pressure 1.0～5.0Mpa that colds pressing, the time 10～150s/mm that colds pressing, take out the cooling back, separates etc. through cutting edge, saw and handle back one-tenth final products.
Thin bamboo strips used for weaving behind the impregnation should be by forward arranging assembly, and target density is set in 0.80～1.10g/cm
3, so that the structural wood mechanical property of the finished product that compacting obtains can satisfy the building girder requirement of strength.
The component of described retardant solution mainly is to human body, the less expansion type flame retardant of environmental hazard, as: APP, phosphoric acid dihydro amine, boric acid or borax, guanyl-urea-phosphate etc.; Also can add synergist pentaerythrite, melamine etc. simultaneously and generate expansion porous charcoal layer material to impel.
Used adhesive often adopts the modified phenolic adhesive of handling through modification, and modification is in order to cooperate the chemical characteristic of fire retardant, admittedly contain 25～40%; Consider that color and luster also can utilize the ultrapas formaldehyde resin of weatherability.
" cold and hot groove " method of employing can utilize thermograde that pickup is improved.
Flame-retardant bamboo laminated board of the present invention reaches the structure material standard through mechanics performance determining; Measure its highest exothermic peak than low more than 1/3 with the taper calorimeter, can reach B1 level flame retardancy construction material standard without fire-retardant same material.
The present invention will be further described below by specific embodiment:
