Abstract
One-step hot-press forming process for a multilayer composite floor board is disclosed, comprising the following steps: slicing or rotary-cutting or saw cutting woods into strips as bezel panel of floor board; rotary-cutting common logs into veneers as veneers; pasting each layer of the veneers together, or cold pressing one layer of veneer and one layer of density board or shaving board and also one layer of veneer again into butt logs; cutting butt logs into dimension boards; cold-pressing dimension boards and strip bezel panels and a one-piece backplane together to form blank board; prepressing blank boards for some time, and then hot-pressing into floor boards without paint; cutting floor boards without paint into floor veneer, and then grooving and tongue, painting, and packaging finished products. The invention can not only improve productivity and decrease energy cost, but also solve the problem of debonding efficiently and keep the product quality stable; thus the invention decreases production cost greatly, is safe and pollution-free.

Summary of the invention
Technical problem to be solved by this invention is to propose a kind ofly can improve the hot-forming production efficiency in floor, cuts down the consumption of energy hot press forming technology method of the multi-layer composite floor of safety and environmental protection and constant product quality.
For solving the problems of the technologies described above, a hot press forming technology method of a kind of multi-layer composite floor of the present invention comprises following processing step:
I, will play the timber of appearance decoration function, through slicing or rotary-cut or sawing forms thickness and width does not wait the strip specification solid wood skin of (being decided according to the actual requirements), as the panel on floor; Common rounding is become the wooden skin of different-thickness, as veneer;
II, on the face of described veneer coating binder, the grain direction of described every layer of veneer is crisscross, and described each layer veneer is bonded together, and perhaps described one deck veneer is added one deck density board or particieboard and then adds the described veneer of one deck, at 12～15kg/cm
2Pressure condition under the synthetic base material of colding pressing;
III, the above-mentioned base material four limit essences of pressing certain hour are cut into dimension board;
IV, upper and lower two surfaces of above-mentioned dimension board are colded pressing with whole backboard with described strip specification panel respectively be in the same place, at 12～15kg/cm
2The synthetic blank flat of pressure condition;
V, with behind the above-mentioned blank flat precompressed certain hour, be 11～13kg/cm at pressure
2, be hot pressed into ground laminin plate under the condition that temperature is 100 ℃～130 ℃.
VI, with plain plate after health, burst becomes ground plate, tongue and groove, paint, packed products then.
A hot press forming technology method of above-mentioned a kind of multi-layer composite floor, the time of colding pressing in the Step II is 40～60 minutes.
A hot press forming technology method of above-mentioned a kind of multi-layer composite floor, the squeeze time among the step V is 40～60 minutes, hot pressing time 10～17 minutes.
A hot press forming technology method of above-mentioned a kind of multi-layer composite floor, described adhesive adopts the environmental protection glue adhesive agent, compose final products after burst size of methanal less than 0.5mg/L.
The present invention by using modified adhesive, adopts a hot pressing to reach repeatedly cold-press process owing to adopted technique scheme, not only enhance productivity, cut down the consumption of energy, and subtract the degumming problem of having determined effectively, greatly reduce production cost, safety and environmental protection and steady quality.
