preparation example Construction

[0048] The present invention provides the preparation method of the high-strength wood fiber board described in the above scheme, comprising the following steps:

[0049] mixing the raw materials for the preparation of the fiberboard layer to obtain a mixture;

[0050] Pave the mixture into a slab, and after compaction, obtain a single-layer board;

[0051] The single-layer boards are stacked into a mold, molded, and the mold is removed, and the obtained boards are sequentially dried, sanded and cured to form a fiber board layer to obtain a high-strength wood fiber board.

[0052] The invention mixes the preparation raw materials of the fiber board layer to obtain the mixture. The present invention has no special requirements on the mixing process, as long as the preparation raw materials can be mixed evenly. In the embodiment of the present invention, specifically, mixing equipment is used to stir for 40 to 60 minutes.

[0053] After the mixed material is obtained, the pre...

Embodiment 1

[0069] 1. Mixing of raw materials: 15 parts of light-burned magnesium oxide, 12 parts of magnesium sulfate, 5 parts of talcum powder, 1.5 parts of magnesium phosphate, 2 parts of sulfuric acid (mass fraction is 52%); add 6 parts of water to the above ingredients, stir until uniform; then Add 12 parts of 3-10mm pine fiber, 28 parts of 1-3mm poplar fiber, 25 parts of 100-200 mesh wood flour, and stir for 45 minutes with the mixing equipment to obtain the mixture;

[0070] 2. Slab laying: the mixed material is sent through the automatic laying equipment, and the formed slab is evenly laid on the entire width through the automatic feeding hopper, and the laying thickness is 40mm;

[0071] 3. Preliminary compaction: put it into a 3200T press for compaction and consolidation, the pressure is 15MPa, and keep for 20s to obtain a single-layer board;

[0072] 4. Crystallization and solidification: stack the single-layer boards on the pressure mold, one mold stacks 25 sheets, press the p...

Embodiment 2

[0081] 1. Mixing of raw materials: 18 parts of light-burned magnesium oxide, 15 parts of magnesium sulfate, 6 parts of talcum powder, 2 parts of calcium phosphate, 3 parts of sulfuric acid (55% by mass); add 5 parts of water to the above ingredients, and stir until uniform; then Add 15 parts of 3-10mm straw fiber, 25 parts of 1-3mm straw fiber, 25 parts of 100-200 mesh wood powder, and stir for 40 minutes with the mixing equipment to obtain the mixture;

[0082] 2. Slab laying: the mixed material is sent through the automatic laying equipment, and the formed slab is evenly laid on the entire width through the automatic feeding hopper, and the laying thickness is 60mm;

[0083] 3. Preliminary compaction: put it into a 3200T press for compaction and consolidation, the pressure is 12MPa, and keep for 25s to obtain a single-layer board;

[0084] 4. Crystallization and solidification: stack the single-layer boards to the pressure mold, stack 20 sheets in one mold, pressurize the pr...

Abstract

The invention provides a high-strength wood fiber board and a preparation method thereof, belonging to the technical field of fiber boards. The high-strength wood fiberboard comprises the fiberboard layer, wherein the fiberboard layer is mainly composed of magnesium oxide, plant fiber and inorganic salt, the magnesium oxide and the inorganic salt have a good waterproof effect, and the plant fiber has good heat insulation performance. Furthermore, by controlling the proportion of the phosphate and the grading of the plant fiber, the fiberboard has high strength. Moreover, a decoration layer and a sealing layer are adhered to the two sides of the surface of the fiber board layer, and compared with a traditional SPC stone-plastic board, the wear-resistant, scratch-resistant and stain-resistant performance of the high-strength wood fiber board is improved.

Description

technical field [0001] The invention relates to the technical field of fiberboards, in particular to a high-strength mineral wood fiberboard and a preparation method thereof. Background technique [0002] SPC stone-plastic board is made of polyvinyl chloride (PVC) powder, stone powder, stabilizer, plasticizer, lubricant, filler and other raw materials mixed in a certain order, added to the twin-screw machine for extrusion and calendering, and the surface is laminated with PVC color. Membrane decorative layer, as a decorative board, is a kind of board used in various occasions due to its waterproof characteristics. However, SPC stone-plastic panels have problems such as poor thermal insulation performance. Contents of the invention [0003] The object of the present invention is to provide a high-strength mineral wood fiber board and a preparation method thereof. The high-strength mineral wood fiber board prepared by the invention has good thermal insulation performance on...
