Abstract

The invention relates to a method for making an anti-abrasion and fire-retardant panel by quick growing wood. The method comprises the following processes: rotatably cutting a single board, preparing fire-retardant soaking glue, soaking the single board into the fire-retardant soaking glue, laying and densifying the panel and so on. The fire-retardant soaking glue is preparing by mixing urea-modified melamine glue, an intensifier and a flame retardant; the single board is obtained by rotatably cutting the quick growing wood; a vacuum pressurizing and impregnating process is adopted to make the soaking glue infilter wood tissues, so as to improve the performances of fire retardance, smoke abatement and agglutination; then three pieces of single boards are stacked and laid through crisscrossing textures of the single boards; and the thickness of the panel is 4+/- 0.5 mm, and the density reaches 1.0 to 1.2g/cm3 after the single boards are hotly pressed and densified. The panel has the advantages of fire retardance, smoke abatement, stable abrasion resistance, strong mildew resistance and strong weather resistance.

Description

The method for producing wear-resistant flame-retardant panel of fast growing wood

Technical field

The present invention relates to a kind of glued board producing method, the production method of especially wear-resisting and fire-retardant gummed panel.

Background technology

Wear-resisting wood panel, the most frequently used means are to adopt famous and precious high density material to make panel, and the raw material difficulty is asked, the cost height; Or with the surperficial method that is coated with the alundum (Al wearing layer, be the wearability that substitutes wooden top layer with the wearability of alundum (Al rete, fundamentally do not solve the wearability problem of timber skin panel itself.CN1404975 discloses Ning Baiyi " production technology of solid wood technology composite reinforced board " successively, adopts famous and precious carpentery workshop surface layer plates such as black walnut, husky Billy, safe shaddock exactly, exists the problem that raw material lacks, cost is high.CN1164600 disclose Mr.'s Han Shuxiang " Wooden face fire-resistant plaque and method for making thereof ", do basic unit with fire-retardant flaggy, do not do wear-resisting and flame treatment to wooden surface layer.In the prior art, many maceration extracts that have gluing and anti-flaming function concurrently because of multiple solvent dilution is arranged glue concentration and be not added with the reinforcing agent that helps increase adhesive strength, the adhesive strength of dipping glue is reduced, influenced the bonding quality that glues together panel.

Summary of the invention

At the above-mentioned deficiency of prior art, the technical problem to be solved in the present invention has 3 points: one provides a kind of help strengthening bonding strength and fire-retardant dipping glue.Two provide a kind of method for producing wear-resistant flame-retardant panel of fast growing wood.Three provide a kind of wear-resistant flame-retardant panel of fast growing wood.

The technical scheme that solves the problems of the technologies described above is: the method for producing wear-resistant flame-retardant panel of this fast growing wood, include the mating formation and closely knit technology of fire retardant glue dipping, panel of preparation, the veneer of rotary-cut, the flame-retardant impregnating glue of veneer, and it is characterized in that:

(1) preparation of flame-retardant impregnating glue: by glue, fire retardant and reinforcing agent three partially mixed forming;

A, commercially availablely buy 25 ℃ and be coated with the urea-modified three polyamine glue that-4 glasss of viscosity are 18-22s, standby;

B, by following raw materials according and weight portion thereof: 30-45 part phthalic anhydride, 65-70 part triethanolamine, 130-140 part water, be heated to 100 ℃, normal pressure down reaction 20min to make reinforcing agent standby;

C, be mixed into the reinforcing agent that fire retardant, 5-10 part borax, 15-25 part APP, 0.5-1 part ammonium molybdate, 30-40 part ammonium sulfate, 30-40 part diammonium hydrogen phosphate, 15-25 part are made by the B method by following raw materials according and weight portion thereof, mixing and stirring;

The preparation of D, retardant solution: the fire retardant that 3 weight portions are made by the C method, 7 weight parts waters mix;

Make this flame-retardant impregnating glue after the retardant solution that makes of the urea-modified melamine glue that fetches with 7 weight portions, 3 weight portion D methods mixes at last;

(2) fire retardant glue of veneer dipping: wet veneer that earlier will rotary-cut is got off from fast growing wood places in the immersion can, vacuumize 0.05-0.08MPa, keep 10-15min, in the aforementioned flame-retardant impregnating glue suction immersion can that makes, be pressurized to 1-1.2MPa, pressurize dipping 1-2h, keep 30min behind the 0.05-0.1MPa that reduces pressure again after, take out veneer, low temperature drying to moisture content is 12%-15%;

(3) mating formation of panel with closely knit: get three veneers after (2) impregnation and dry the processing, paste mutually the veneer texture orthogonal stack to mat formation carry out hot pressing, temperature 100-120 ℃, pressure 3.0-4.2MPa keeps 4-5min, unloads plate.

The specific embodiment

Embodiment 1: earlier will 30 parts of phthalic anhydrides, 65 parts of triethanolamines, 130 parts of water heat to 100 ℃ after mixing, normal pressure down reaction to make reinforcing agent in 20 minutes standby.Again 5 parts of boraxs, 15 parts of APPs, 0.5 part of ammonium molybdate, 30 parts of ammonium sulfate, 30 parts of diammonium hydrogen phosphates, 15 parts of aforementioned made reinforcing agents are mixed together to stir and make fire retardant.

Use aforementioned fire retardant 3 weight portions and 7 weight portion water for industrial use mixing and stirring again, be mixed with retardant solution.

The urea-modified melamine glue stirring and evenly mixing of buying with aforementioned retardant solution of 3 weight portions and 7 weight portions at last, it is standby to make flame-retardant impregnating glue.

The China fir rotary cut venner is taken advantage of the wet immersion can of putting into, vacuumize 0.05MPa, keep 10min, in the aforementioned flame-retardant impregnating glue suction immersion can that makes, be pressurized to 1MPa, pressurize dipping 2h, the 0.05MPa that reduces pressure again keeps taking out veneer behind the 30min, being dried to moisture content is 12%, get three China fir veneers after above-mentioned processing, vertical in length and breadth or horizontal from top to bottom crisscross the laminating of texture mated formation, hot pressing 5min in 100 ℃, pressure 4.2MPa, post processings such as taking-up back cooling cutting edge, getting thickness is 4mm, density is 1g/cm 3The China fir wear-resistant flame-retardant panel.
