Description
Technical field
Glass fabric strengthening material is added in the middle of Wooden veneer overlay coating and cellular board substrate layer the present invention relates to one kind
Expect the method for mechanical property.
Background technology
In the market of furniture and indoor design, timber and made sheet material are most widely used, most sexual valences
The material of ratio.In recent years, the application of wooden honeycomb composite plate overcomes solid wood furniture and easily deforms upon and be difficult lacking for drying
Point, makes furniture have the good characteristic of light weight, reduces the cost of transport and the cost of packaging.In plate fitment production,
Sheet material of the thickness not less than 18mm and some auxiliary accessories etc. can use wooden honeycomb composite plate to replace, and sheet material is thicker, its property
Can be more obvious.But there is also obvious shortcoming, its mechanical strength, special bending strength and bending resistance bullet for wooden honeycomb composite plate
Property modular ratio it is relatively low, limited to wooden honeycomb composite plate it is extensive, efficient utilization.
The content of the invention
The shortcomings of the invention aims to solve soft cellular board matter, low intensity and alleviate that wood supply is nervous to be showed
Shape, and a kind of method of the glass fiber reinforcement Wood honeycomb board provided.
This method is characterized in that it comprises the following steps：
Step 1: thickness is used into epoxy resin, curing agent and thickness 10-15mm for 0.1-0.2mm glass fabric
Cellular board paste, cellular board deflection be 100-200 (g*cm), grammes per square metre be 600-800 (g/m2), epoxy resin is consolidated with ethylenediamine
The proportioning of agent is 4:1-3:1, epoxy resin resin added is 300-400g/m2, one side applying glue；
It is cold-pressed Step 2: the glass fabric enhancing cellular board in step one is placed in cold press, the cold pressing time is 60-
90min, pressure is 0.6-1.0Mpa；
Step 3: thickness is pasted into the glass after being cold-pressed through step 2 using milky white adhesive for 1.0-2.0mm fraxinus mandshurica veneer
Glass fiber cloth enhancing cellular board upper surface, the resin added of milky white adhesive is 170-200g/m2, one side applying glue, used before applying glue
Fraxinus mandshurica veneer is pasted face and polished flat by sand paper, and with acetone treatment so as to clean surface；
Step 4: thickness is pasted into the glass after being cold-pressed through step 2 using milky white adhesive for 1.5-3.0mm board using poplar board
Fiber cloth strengthens cellular board lower surface, and the resin added of milky white adhesive is 200-240g/m2, one side applying glue, before applying glue use sand paper
Veneer is pasted into face to polish flat, and with acetone treatment so as to clean surface；
Step 5: glass fiber reinforced composite cellular board after the veneer overlay by step 3 and step 4 is placed in into cold pressing
Carry out being cold-pressed for second in machine, the cold pressing time is 30-60min, and pressure is 0.4-0.6Mpa.After above step, that is, obtain
By the wood composite cellular board of glass fiber reinforcement.
The inventive method is simple, can effectively strengthen the mechanical property of wood composite cellular board, enhanced through glass fabric
Wood composite cellular board bending strength improves 5.5-6.5 times, 0.5-1.5 times of Deflection Modulus of Elasticity raising.
The present invention improves the intensity of cellular board, expands it and uses scope, alleviates timber resources shortage, disparities between supply and demand
The situation become increasingly conspicuous, realizes the excellent use of bad material, alleviates timber resources shortage, the situation that disparities between supply and demand become increasingly conspicuous, with weight
Big economic and social benefit.
