Abstract
The invention discloses a method for manufacturing a flame-retardant core-board. The method mainly includes steps that a single board as one of raw materials for production of the core-board is in flame-retardant treatment under the normal condition by the aid of ZRP flame retardant liquor; and then adhesive which is mixed by modified urea resin, ZRP flame retardant, flour and phosphoric acid is coated on the single board by the aid of an applicator after the flame retardant treatment of the single board, the single board and a core are in primary prepressing and hot pressing operation to be manufactured into a board blank after being assembled, the adhesive is coated on the board blank by the aid of the applicator, the board blank is assembled with veneer used for a surface layer, and the flame-retardant core-board with excellent performances is manufactured after secondary prepressing and hot pressing operation. As shown in the process, the method for manufacturing the flame-retardant core-board is simple, only the single board as one of the raw materials is treated under the normal condition, and accordingly the core-board with an excellent flame-retardant performance can be obtained.
Description
Technical field
The present invention relates to a kind of production method of timber industry wood-based plate, the manufacturing approach of the flame retardant blockboard that particularly a kind of production technology is comparatively simple, fire resistance is good.
Background technology
Core-board is the main material of present interior decoration, construction and decoration, furniture making etc.The making of core-board is by the small dimension wood of poplar or China fir etc., the plate core that leftover pieces are processed, both sides with the veneer of poplar or Eucalyptus etc. through a hot-press gluing with again with the wooden skin of poplar or Okoume etc., glue together through secondary hot pressing and to process.But because there is bigger fire hidden danger in the inflammability of core-board, so must carry out flame treatment.
At present, the fire resistance of selling on the market preferably flame retardant blockboard producing constantly, for guaranteeing that its fire resistance is with used whole wood material-central layers, veneer etc.; Method through vacuumizing and pressurizeing in vacuum/pressurized canister is carried out flame treatment with fire resistant fluid, carries out drying then; Process flame retardant blockboard by the technology of core-board production again; The flame retardant blockboard fire resistance of producing thus is better, but its shortcoming is the production technology more complicated, and production cost is also higher relatively.Also have on the market wood material is carried out the production technology of flame treatment under normal conditions with fire resistant fluid, but the flame retardant blockboard of processing thus, its fire resistance is not fine, does not reach high-level fire-retardant requirement.
Summary of the invention
The present invention has overcome the deficiency that exists in the above-mentioned prior art, and the manufacturing approach of the comparatively simple and flame retardant blockboard that fire resistance is good of a kind of production technology is provided.
Technical scheme of the present invention is achieved in that
A kind of manufacturing approach of flame retardant blockboard comprises:
1.; Get moisture content and be 15～20%, thickness is the board using poplar board of 2～2.8mm; Put into concentration and be 15～30%, temperature is that 30～60 ℃ the ZRP fire retardant aqueous solution flooded 20～60 minutes, after taking out veneer and veneer being drained, it is for use to send veneer dryer to be dried to moisture content≤12%;
2.; Get 40～60 kilograms of cyanurotriamide modified urea resins, 5～15 kilograms of ZRP fire retardants, 2～8 kilograms in flour, phosphatase 11～5 kilogram, in glue mixer, stir after 5 minutes, put into glue spreader; Then that drying is good veneer gluing, the glue-spread of veneer are single face 170～250g/ square meter;
3.; Get thickness and be 12～15mm, moisture content and be 11～14% machine and piece together China fir plate core, carry out assembly, put into the cold press precompressed 40 minutes with veneer behind the above-mentioned gluing; Preload pressure is 0.8MPa; Precompressed finishes after a hot pressing is carried out in repairing, processes slab, and the process conditions of hot pressing are: 110 ℃ of temperature, 5 minutes time, pressure 1.0MPa;
4., the slab after the hot pressing carries out sanding, gluing again through 3-5 days healths; The prescription of used adhesive is 2. the same in the step with the, and glue-spread is 130～200g/ square meter, with the wooden skin assembly as face, end decoration; Advanced the cold press precompressed 30 minutes, preload pressure is 0.8MPa, and precompressed finishes laggard hot press secondary hot pressing; The process conditions of hot pressing are: 110 ℃ of temperature, 3 minutes time, pressure 1.0MPa, and be placed to second day after secondary hot pressing finishes and saw limit, sanding, promptly obtain finished product.
Adopted the principle of the present invention and the beneficial effect of technique scheme to be:
The present invention is that a kind of model of employing is the water-soluble flame retardant of ZRP; This ZRP fire retardant is to buy from the Beijing Shanda Huayuan Science & Technology Co., Ltd; The not only environmental protection of the characteristics of this fire retardant, fire resistance are good; And not only can be used for wood materials flame treatment but also can with the urea-formaldehyde resin adhesive blend through modification, make adhesive behind hot-press solidifying, glue-line produces good flame-retardant effect; The present invention mainly is one of the raw material of use during core-board an is produced veneer, at first under the normality condition, carries out flame treatment with the ZRP fire retardant aqueous solution; To pass through the veneer of flame treatment then; Coat the adhesive that modified urea-formaldehyde resin mixes with the ZRP fire retardant by glue spreader; With carry out again slab being coated the adhesive that modified urea-formaldehyde resin mixes with fire retardant through glue spreader, with the wooden skin assembly that is used for the top layer after a precompressed and heat pressing operation process slab behind the plate core assembly; After secondary precompressed and heat pressing operation, promptly process well behaved flame retardant blockboard.
Can see that from above-mentioned process the method for the flame retardant blockboard that the present invention makes is comparatively simple, only the veneer to one of raw material has carried out the processing under the normality condition, can obtain the good core-board of fire resistance.
By the flame retardant blockboard that above-mentioned manufacturing process is processed, not only fire resistance meets the above requirement of B level in the GB8624-2006 standard, and physicochemical property meets the GB/T5849-2006 standard-required.
