Problems solved by technology

[0005] To sum up, the current veneering technology of melamine-impregnated paper is not only due to the use of urea-formaldehyde glue, which leads to high aldehyde content, which causes environmental pollution, but also increases energy consumption due to the high temperature.

specific Embodiment 1

[0025] Glue the upper and lower sides of the core board 1 and paste the eucalyptus middle layer board 2. Under normal temperature, press 10 MPa, cold press for 30 minutes, trim the surface after cold pressing, and get a semi-finished product. The resulting semi-finished product was placed at a temperature of 110° C. under a pressure of 10 MPa, and hot-pressed for 8 minutes. After hot-pressing, the first health preservation was carried out for 7 days.

[0026] After the curing, the surface of the semi-finished product is sanded for the first time, and then the surface of the semi-finished product is greasy after sanding, and the steps of curing and sanding are repeated again.

[0027] The semi-finished product after the second sanding is polished, and the polished semi-finished product is glued on both sides and pasted with poplar board cortex 3. At normal temperature, the pressure is 10Mpa and cold pressed for 15 minutes.

[0030] Glue the upper and lower sides of the core board 1 and stick the eucalyptus wood middle layer board 2. Under normal temperature, the pressure is 9Mpa, and the cold pressing is carried out for 45 minutes. After the cold pressing, the surface is trimmed to obtain a semi-finished product. The resulting semi-finished product was placed at a temperature of 115° C. under a pressure of 9 MPa and hot-pressed for 8 minutes. After hot-pressing, the first health preservation was carried out for 7 days.

Abstract

The invention discloses a manufacturing method of a melamine ecological plate. The ecological plate is compounded with a core plate, a middle plate layer, a slab layer and melamine impregnated paper. The core plate is stuck to the middle plate layer after an upper face and a lower face of the core plate are glued. After cold pressing and hot pressing, the core plate is repeatedly maintained, trimmed and sanded, and is glued and stuck to the slab layer. Similarly, after the cold pressing, hot pressing, trimming and sanding, the core plate is glued and stuck to the melamine impregnated paper. The ecological plate manufactured by the method is energy-saving and environment-friendly, and under the condition that energy consumption is not increased, the ecological plate is cold pressed before hot pressing so that a composite structure of the plate is firmer. Furthermore, in the process of pressing and gluing the melamine impregnated paper, emulsion free of formaldehyde is used as binding agent, and accordingly formaldehyde content of the plate is reduced.

Description

technical field [0001] The invention relates to a home decoration board, in particular to a manufacturing method of a melamine ecological board. Background technique [0002] Melamine board, the industry prefers to be called ecological board, the full name is melamine impregnated film paper veneer wood-based board. It is to soak paper with different colors or textures in melamine resin adhesive, then dry to a certain degree of curing, and stick it on the surface of particleboard, moisture-proof board, medium density fiberboard, plywood, blockboard or other hard fiberboard , a decorative panel made by hot pressing. The advantage of this kind of board is that the surface is smooth, not easy to deform because the expansion coefficient of both sides of the board is the same, the color is bright, the surface is more wear-resistant, corrosion-resistant, and the price is economical. The disadvantages of this type of board are: [0003] 1. Urea-formaldehyde glue with low price an...
