Embodiment 1

[0051] 1. Preparation and transportation of shavings: OSB has higher requirements for raw materials than ordinary particleboards. Generally, its raw materials are single tree species, and the diameter of logs is generally above 80mm. Long planer is used to slice them along the direction of wood fibers. Processing, so that the processed shavings are thin and long strips, and the geometric dimensions are: length 100-120mm, width 14-20mm, thickness 05-0.7mm. In order to ensure that the thin and long shavings are not broken during transportation, the transportation equipment generally adopts belt conveyors, and it is not suitable to use pneumatic conveying equipment. Avoid using screw conveyors to prevent the shavings from being broken under the impact of the cyclone vortex and the extrusion of the spiral blades. Affect the paving effect, and ultimately affect the mechanical properties of the board.

[0052] 2. Drying of shavings: Because OSB shavings are thin and long, it is best...

Abstract

The invention relates to a plate, in particular to an impregnated paper finished OSB composite floor and a preparation method. The impregnated paper finished OSB composite floor sequentially comprises an OSB base material layer, a veneer layer, a buffer paper layer, a balance paper layer and a sprayed decorative paper layer from bottom to top. The longitudinal static bending intensity of the OSB base material layer is larger than or equal to 50 MPa, and the water absorption thickness swelling rate of the OSB base material layer is smaller than or equal to 12%. The veneer layer is a poplar bleached veneer, and the thickness ranges from 0.6 mm to 1.2 mm. The buffer paper layer is impregnated kraft paper with the thickness of 0.4 mm to 0.6 mm, and the glue quantity is 80% or above. The weight of the balance paper layer ranges from 70 g to 80 g, and the glue quantity ranges from 100% to 120%. The weight of the sprayed decorative paper ranges from 70 g to 80 g, and the glue quantity ranges from 100% to 120%. The impregnated paper finished OSB composite floor has high environment friendliness, stability and water resistance.

Description

technical field [0001] The invention relates to a board, in particular to an OSB composite floor with an impregnated paper finish and a preparation method thereof. Background technique [0002] Flooring is an essential material in interior decoration. At present, laminate flooring accounts for about 70% of the flooring industry, and has a large market share. Laminate floors generally use urea-formaldehyde resin glue as the adhesive, which has poor water resistance and high water-absorbing thickness expansion rate. Nowadays, the quality of the laminate flooring market is mixed. The limit of formaldehyde emission is generally E1 level, or even E2 level, which seriously affects the indoor air quality after decoration. Moreover, the shortage of resources and the gradual decline of internal quality make consumers doubtful. Oriented strand board (OSB) is made of natural poplar wood, and its formaldehyde emission limit reaches the formaldehyde-free level. At the same time, OSB ha...
