Problems solved by technology

In the prior art, many impregnation solutions with both adhesive and flame-retardant functions have a variety of solvents that dilute the concentration of the glue and do not add a reinforcing agent that helps increase the adhesive strength, which reduces the adhesive strength of the impregnated glue. , affecting the bonding quality of the glued panels

Embodiment 2

[0017] Example 2: Refer to the raw materials and weight values ​​of Example 2 in the table, and prepare the flame-retardant impregnating glue in the same way as Example 1. Put the rotary-cut poplar veneer into the impregnation tank by wet, vacuumize 0.08MPa, and keep After 15 minutes, pump in the flame retardant impregnation glue, pressurize to 1.2MPa, keep it for 1h, then depressurize it to 0.08MPa, keep it for 30min, take out the veneer, dry it to a moisture content of 15%, take three pieces of veneer after the above treatment, Vertically, horizontally and vertically laminated pavement, hot pressing at 120°C for 4 minutes, pressure 3MPa, after cooling, take out the trimming and other post-processing, the thickness is 4.5mm, the density is 1.1g / cm 3 Poplar wear-resistant and flame-retardant panels.

Embodiment 3

[0018] Example 3: Referring to the raw materials and their weight parts in Example 3 in the table, the same method as in Example 1 was used to prepare the flame-retardant impregnating glue, and the pine rotary-cut veneer was wetted and impregnated.

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

technical field [0001] The invention relates to a production method of plywood, in particular to a production method of a wear-resistant and fire-resistant plywood panel. Background technique [0002] Wear-resistant wooden panels, the most commonly used method is to use expensive high-density materials as panels, raw materials are difficult to find, high cost; or the method of coating the surface with aluminum oxide wear-resistant layer is to use aluminum oxide film Abrasion resistance replaces the abrasion resistance of the wood surface layer, and does not fundamentally solve the abrasion resistance problem of the wood surface panel itself. CN1404975 discloses Ning Baiyi successively " the production technology of solid wood process composite strengthened board ", adopts black walnut, Sapele, Thai pomelo and other famous and precious woods to make face ply board exactly, there is the problem of raw material shortage, high cost. CN1164600 discloses Mr. Han Shuxiang's "wood ...
