Embodiment 1

[0040]First take 2kg of melamine-modified urea-formaldehyde resin glue, add 0.4kg of flour and mix evenly, then put it into the glue spreader. Take 12 eucalyptus veneers of 1270×640×1.7mm, and lay 4 pieces of eucalyptus veneers that have not been glued directly on the workbench, which is the bottom veneer; take the other 4 pieces of eucalyptus The glue machine is used to apply glue to ensure that the corners of the two boards coated with glue are evenly distributed, and then these 4 pieces of eucalyptus veneer (middle layer glue board) coated with glue on both sides are placed on the bottom veneer. Lay the remaining 4 unglued eucalyptus veneers for billet assembly, the middle plywood and the bottom veneer are at 90°, that is, the bottom plywood is horizontal and the middle plywood is vertical or the bottom plywood is vertical and the middle plywood The rubber boards are arranged horizontally and criss-crossed to form slabs with a specification of 2540×1280×5.1mm. Complementary...

Embodiment 2

[0042] First take 2.2kg of melamine-modified urea-formaldehyde resin glue, add 0.44kg of flour and mix evenly, and then put it into the glue spreader. Take 8 pieces of eucalyptus veneer with a size of 1270×640×3.2mm, put the 8 pieces of eucalyptus veneer directly into the gluing machine for one-sided gluing, and ensure that the angle distribution of the glued board surface is even. Arrange 4 glued eucalyptus veneers horizontally on the workbench, with the glued side facing up, and then put the whole board core with a size of 2540×1280×11mm, and then put the glued The glued side of the other 4 eucalyptus veneers that have been glued face down to form a blockboard slab with a size of 2540×1280×17.5mm. After the blank assembly is completed, put the blockboard slab into the pre-pressing machine Pre-compressed in the middle, and pre-compressed at room temperature for 50 minutes. Put the pre-pressed blockboard slabs into a hot press for hot pressing, so that the layers between the ...

Embodiment 3

[0044] First take 50kg of melamine-modified urea-formaldehyde resin glue, add 13kg of flour, mix and stir evenly, and then put it into the glue spreader. Take 20 pieces of 1270×640×1.7mm eucalyptus veneers, and apply glue to 8 pieces of eucalyptus veneers through a gluing machine to ensure that the corners of the glued boards are evenly distributed. Lay 4 eucalyptus veneers that have not been glued on the workbench, which is the bottom veneer; take the other 8 eucalyptus veneers and apply glue through the gluing machine to ensure the angular distribution of the two glued boards Evenly, then place the 8 pieces of eucalyptus veneer (middle layer x 2) with glue on both sides on the bottom veneer. For blank assembly, the middle rubber sheet and the bottom veneer are arranged at 90°, that is, the bottom rubber sheet is horizontally arranged and the middle layer rubber sheet is vertically arranged or the bottom layer is vertically arranged and the middle layer rubber sheet is horizo...

Abstract

The invention relates to a melamine plate, which comprises a layer of substrate plate and a layer of melamine paper, wherein the melamine paper is pasted on the substrate plate surface. A preparing method of the melamine plate comprises the steps that after a raw material plate is subjected to hot pressing, putty is taken for filling up the raw material plate, in addition, sanding is carried out, one side of the raw material plate flattened through filling up is puttied once by the putty, and after 12 to 48 hours, the side is subjected to once sanding; the other side of the raw material plate is puttied once by the putty through adopting the same method, then, the side is subjected to once sanding, and after the aging is carried out for 1 to 3 days, the melamine paper can be pasted. The melamine plate has the advantages that the quality of obtained finished products is good, the finished product rate is high, the formaldehyde content is low, and the production cost is low.

Description

technical field [0001] The invention relates to an artificial board and a preparation method thereof, in particular to a triamine board and a preparation method thereof. Background technique [0002] Eucalyptus is one of the main plantation fast-growing tree species in my country. It takes 1 year to mature, 3 years to mature, and 5 years to harvest and utilize. Eucalyptus wood has been mainly used for the production of wood chips and pulp for a long time, and the production of eucalyptus hardboard and particleboard has a relatively long history. In recent years, a large number of fast-growing eucalyptus plantations have been used to produce veneer and sawn timber. up. [0003] Melamine veneer, referred to as melamine board, also known as veneer, also known as one-time forming board; it is made of base material (medium fiberboard, particle board, blockboard, plywood, etc.) Amine glue) made by high temperature pressing. At present, the production of melamine boards on the ...
