Embodiment 1

[0045] Embodiment one (17.5mm plywood core corrugated board)

[0046] 1. Substrate production (15mm plywood substrate):

[0047] 1. Glue coating and blank assembly: Glue 5 pieces of 1.8mm eucalyptus short-core veneer, and the glue is soybean glue. Glue amount 200g / m 2 , The veneers are sorted according to the feeding standards, mainly sorted according to their appearance grades, and the moisture content of the materials that meet the standards must be strictly controlled. According to the design plan, 5 layers of glued short cores and 4 layers of uncoated long cores are assembled, criss-crossing;

[0048] 2. Cold pressing: put the slabs assembled into the cold pressing machine for cold pressing, the time is 90min, and the pressure is 1.0MPa;

[0049] 3. Hot pressing: Hot press the cold-pressed slab at a temperature of 120°C for 18 minutes and a pressure of 1.0 MPa. After hot pressing, the moisture content of the slab is controlled within 12%.

[0050] 4. Sanding: sanding t...

Embodiment 2

[0066] Embodiment two (17.5mm blockboard core Kangnai board)

[0067] Production of a substrate (17mm blockboard substrate):

[0068] 1. Glue coating and billet assembly: Glue coating for 12mm glulam, the glue is soybean glue. Glue level 220g / m 2 , according to the design plan, paste a layer of 2.0mm poplar short core on the top and bottom of the glued wood;

[0069] 2. Cold pressing: put the slab that has been formed into a cold pressing machine for cold pressing, cold pressing for 90 minutes, and a pressure of 0.8 MPa;

[0070] 3. Hot pressing: Hot press the cold-pressed slab at a temperature of 120°C, a time of 500 seconds, and a pressure of 0.8 MPa. After hot pressing, the moisture content of the slab is controlled within 10%.

[0071] 4, sanding: the slab that hot-pressing is finished carries out constant-thickness sanding, and constant thickness is to 15mm, and abrasive belt is the combined abrasive belt of 60 orders and 150 orders.

[0072] 5. Scraping and greasy: F...

Abstract

The invention relates to a CON-AID plate and a manufacturing method thereof. The CON-AID plate comprises a center base material layer, and is characterized in that a balance layer, a buffering layer and a decorative layer are sequentially arranged outside the base material layer; the balance layer is made from homogenous MDF or HDF; the buffering layer is made from dipping ecological paper; and the environment-friendly level of each layer is the E0 level. Manufacturing of the CON-AID plate includes the following steps of base material manufacturing, buffering layer manufacturing, surface layer decorative dipping paper manufacturing and CON-AID plate manufacturing. According to the CON-AID plate and the manufacturing method thereof, needed raw materials are subjected to environment-friendly control, the formaldehyde release amount achieves the E0 level, meanwhile, the subsequent painting and colored drawing process is not needed, the decorative cost is saved, and pollution is reduced.

Description

technical field [0001] The invention relates to a corrugated board and a manufacturing method thereof, belonging to the field of functional wood material processing. Background technique [0002] With plywood and blockboard core as the base material, it is commonly called ecological board after being impregnated with film paper. It has good mechanical properties, decorative properties and environmental protection properties such as paint-free, strong wood feeling, good nail holding power, and convenient sawing. . [0003] Eco-board is a new type of interior decoration board. It has been developing rapidly since 2012. It has a trend of unifying home decoration materials and has become the most important material for interior decoration. At present, it has accounted for about 70% of wood-based panel surface decoration materials. After 7 years of development, the quality has been steadily improved, and the product series has also been well developed. Its environmental protect...
