Embodiment 1

[0059] Embodiment 1 flame retardant dipping method

[0060] S1: Preparation of flame retardant base material, immerse 1.7mm poplar veneer and 0.5mm poplar bark in a uniform aqueous solution of nitrogen, phosphorus and boron flame retardant with a concentration of 25%, the temperature of the flame retardant is 30°C, and the concentration is 25%. Take it out after soaking for 30 minutes, balance the water content to 20% under natural conditions, and dry it to the water content of 8% with a mesh belt dryer.

[0061] S2: Blank assembly, for the flame-retardant poplar veneer after flame-retardant treatment, use amino resin solution at a rate of 400g / m 2 After the glue is distributed, the flame-retardant plywood (17mm) is formed according to the principle of cross-symmetry of odd and even layers, and then a layer of flame-retardant poplar bark with a thickness of 0.5mm is pasted on the upper and lower surfaces of the flame-retardant plywood. 0.4Mpa, temperature 115°C, carry out pre...

Embodiment 2

[0065] Embodiment 2 flame retardant dipping method and flame retardant adhesive method

[0066] S1: Preparation of flame-retardant base material. Immerse 18mm blockboard and 0.5mm poplar veneer in a uniform aqueous solution of intumescent flame retardant with a concentration of 20%. The temperature of the flame retardant is 35°C. Balance the moisture content to 20% under the same conditions, and dry it with a mesh belt dryer to a moisture content of 8%; add a 20% intumescent flame retardant to the adhesive, mix well and stir evenly to obtain a flame retardant containing Adhesive, used for substrate cloth glue assembly, the mass ratio of flame retardant and amino resin solution is 40:100;

[0067] S2: Assemble the billet, use the core strip splicing machine to splice the 18mm flame-retardant blockboard after the flame-retardant treatment, and use the adhesive containing the flame retardant after the splicing is completed, at a rate of 400g / m 2 The amount of cloth glue should b...

Embodiment 3

[0071] Embodiment 3 flame retardant adhesive method

[0072] YA-1: Preparation of flame retardant adhesive, adding a 30% inorganic metal flame retardant to the adhesive, fully mixing and stirring evenly to obtain an adhesive containing flame retardant, which is used for the substrate cloth adhesive group Blank, the mass ratio of described flame retardant and adhesive is 60:100, and described adhesive is amino resin solution;

[0073] YA-2: Preparation of flame retardant core board, mix shavings and flame retardant adhesive in a ratio of 20:3, stir evenly, then pave, pre-press, hot press (pressure 2.5Mpa, temperature 165°C, Time 6min), sawing the edge and 40-100 mesh double-sided sanding treatment to make a flame-retardant core board with a thickness of 16mm;

[0074] YA-3: Blank assembly, use particleboard and high-density fiberboard with a thickness of 0.55mm with an adhesive containing a flame retardant, at 400g / m 2 The amount of glue to be placed is treated with glue, bla...

Abstract

The invention discloses a flame-retardant impregnated film adhesive facing artificial board and a manufacturing method thereof. The flame-retardant impregnated film adhesive facing artificial board mainly comprises a flame-retardant core board, flame-retardant middle boards and an impregnated film adhesive layer; the upper surface and the lower surface of the flame-retardant core board are bondedwith the flame-retardant middle boards through glue, after the flame-retardant core board and the flame-retardant middle boards are pressed, a flame-retardant base material layer is obtained, the upper surface and the lower surface of the flame-retardant base material layer are bonded with impregnated film adhesive layers through glue, and after the flame-retardant base material layer and the impregnated film adhesive layers are subjected to pressing, compounding, edge aligning, a finished product is obtained. In addition, flame-retardant wood veneer layers are included and adhere to the uppersurfaces and the lower surfaces of the flame-retardant middle boards so that the thickness and / or the flatness of the base material layer can be adjusted. The flame-retardant impregnated film adhesive facing artificial board and the manufacturing method thereof have the beneficial effects that a flame-retardant impregnating method and a flame-retardant adhesive agent method are suitable for various wood boards, independent using and combined using can be achieved, and the general applicability is high; and in addition, the method operation process is simple, the treatment cost is low, large-size equipment does not need to be additionally arranged, and the product appearance effect cannot be influenced.

Description

technical field [0001] The invention relates to the technical field of plate processing, in particular to a flame-retardant impregnated film paper-decorated wood-based panel and a manufacturing method thereof. technical background [0002] Adhesive film paper veneer wood-based panel is based on wood-based panels such as plywood, blockboard, particle board, density fiberboard or OSB board, and melamine-formaldehyde resin, urea-formaldehyde resin, etc. Pressed decorative panels. The impregnated film paper veneer wood-based panel is generally composed of film paper and base material. Compared with solid wood sawn timber, impregnated film paper veneered wood-based panels have bright colors, no paint, scratch resistance, good nail holding power, ecological environmental protection, and many excellent properties that natural wood cannot have at the same time. In addition, the source of raw materials Wide range, high wood utilization rate, many product specifications, good proces...
