[0037] Example 1 Production of 18mm plywood core flame retardant ecological board

[0038] Step ① short core flame retardant impregnation treatment: put 3.6mm eucalyptus short core into a vacuum pressurized tank, and carry out vacuum pressure impregnation treatment with uniform nitrogen, phosphorus and boron series flame retardant aqueous solution with a concentration of 12.5%, and impregnate the impregnated Take out the short core of eucalyptus and dry it until the moisture content is less than 12%, and the oxygen index reaches more than 50%;

[0039] Step ② Coating the board core with melamine-modified urea-formaldehyde resin glue evenly on the 11mm plywood board core, the glue amount is 200g / m 2 ;

[0040]Step 3. Assembling the billet, compounding two 3.6mm impregnated eucalyptus short cores on the glued plywood core, and putting them into the cold press for cold pressing within 30 minutes after the billet assembly is completed;

[0051] Example 2 Production of 18mm blockboard core flame retardant ecological board

[0052] Step ① short core flame retardant impregnation treatment: put 3.6mm poplar short core into a vacuum pressurized tank, and carry out vacuum pressure impregnation treatment with an aqueous solution with a concentration of 15% intumescent flame retardant and inorganic metal flame retardant mixed uniformly , take out the impregnated poplar short core and dry it until the moisture content is within 12%, and the oxygen index reaches more than 50%;

[0053] Step 2. Apply glue to the board core. Apply melamine-modified urea-formaldehyde resin glue evenly on the 11mm blockboard core. The amount of glue applied is 210g / m 2 ;

[0054] Step 3. Assembling the blanks, compounding two 3.6mm impregnated poplar short cores on the glued blockboard cores, and putting them into a cold press within 30 minutes after the completion of the assembly for cold pressing;

Abstract

The invention discloses a flame-retardant ecological board and a manufacturing method thereof. The flame-retardant ecological board comprises a board core, short cores, impregnated balance paper and surface layer decoration impregnated paper, the short cores are arranged on the two sides of the board core in a compounded mode, the short cores and the board core are integrally subjected to cold andhot laminating so as to form a substrate layer, the impregnated ecological paper is compounded on the upper surface and the lower surface of the substrate layer, the surface layer decoration impregnated paper is compounded on the upper surface and the lower surface of the impregnated ecological paper, and the substrate layer, the impregnated ecological paper and the surface layer decoration impregnated paper are subjected to double-sided compounding and hot-pressing integrated forming. The flame-retardant ecological board and the manufacturing method thereof have the beneficial effects that the short cores are subjected to impregnation treatment of an impregnant, so that the short cores achieves the inflame-retardant function, the substrate layer formed by bonding the short cores with theflame-retardant function and the board core also has the flame-retardant function, one board connected to a decoration layer is replaced by kraft paper or the balance paper which is impregnated withamino resin with certain flame-retardant function, and therefore the flame retardancy of the board can be improved, and meanwhile, the crack resistance of the surface of the ecological board can alsobe improved.

Description

technical field [0001] The invention belongs to the field of functional wood material processing, and in particular relates to a flame-retardant ecological board and a manufacturing method thereof. Background technique [0002] Ecological board is a new type of interior decoration board. It has good mechanical properties, decorative properties and environmental protection properties such as paint-free, strong solid wood feeling, good nail holding power, and convenient sawing. It generally consists of a substrate layer, a buffer layer, and a decorative layer. composition. Since 2012, the development of ecological panels has been in full swing, and there is a trend of unifying home decoration materials, becoming the most important material for interior decoration. At present, it has accounted for about 70% of the surface decoration materials of wood-based panels. After 7 years of development, the quality has been steadily improved, and the product series has also been well de...
