Description
Technical field
The present invention relates to a kind of preparation method, specially a kind of preparation method of flame-retardant plywood belongs to preparation method skill
Art field.
Background technique
Flame-retardant plywood is veneer to be peeled by juggle or by flitch slicing at veneer, is carried out after flame retardant treatment again to veneer
With the board-like material of adhesive three layers or multilayer made of glued, odd-level veneer is usually used, and make the fiber of adjacent layer veneer
The orthogonal gluing in direction forms, and using beech clamping plate as raw material, produces by a series of technology and technique, sufficiently
The smoke density and poisonous gas index of fire hazard are considered, flame-retardant plywood is using timber as the fire retardant glue of main material production
Plywood can generally overcome the defect of timber to substantially improve due to the retrofit in the reasonability and production process of its structure
With the physical and mechanical property for improving timber, while fire retardant glued board also overcomes the incendive disadvantage of normal plywood, effectively mentions
High glued board flame retardant property, flame-retardant plywood production be sufficiently and reasonably using timber, improve one of wood performance it is important
Method.
Therefore, then a kind of preparation method of flame-retardant plywood is needed to meet on the market the needs of to flame-retardant plywood, though
The preparation method of a variety of flame-retardant plywoods is so had already appeared on the market at present, but as a whole, but there is some mostly
Common fault, one, existing flame-retardant plywood preparation method viscose be B grades of viscoses, cause the inside viscose of glued board inadequate
Closely, glued board after prolonged use is caused the phenomenon that veneer separation occur, secondly, the preparation side of existing flame-retardant plywood
The precision of the single-board materials of method is not up to standard, and glued board after molding is caused cracking phenomena easily occur, thirdly, existing fire retardant glue
The compactor of the preparation method of plywood be voltage hydraulic press, lead to the insufficient pressure in compacting process, thus make glued board it
Between there is gap.
Summary of the invention
The object of the invention is that providing a kind of preparation method of flame-retardant plywood to solve the above-mentioned problems.
The present invention through the following technical solutions to achieve the above objectives: a kind of preparation method of flame-retardant plywood, including with
Lower step:
Step A: selecting timber, selects good linden and checks the drying property of linden, while observing selected linden material
It is whether complete, unfilled corner and free from flaw are had no, and there is good toughness；
Step B: rotary-cut polishing carries out the linden material selected merging peeler to thin processing and linden is processed into size shape
Then shape and the essentially equal cuboid block of thickness will carry out polishing grinding processing in the good timber merging sander of rotary-cut；
Step C: veneer flame retardant treatment, the monolithic linden timber after rotary-cut is polished carry out flame retardant treatment, and in linden timber
Portion carries out cure process, and fire proofing and barrier material will be filled at internal interstices；
Step D: surface treatment will carry out the veneer linden material after flame retardant treatment and carry out surface polishing treatment, and by veneer
Side wall synchronizes polishing；
Step E: smearing viscose, and viscose is smeared in the front and back sides for carrying out treated veneer and carries out viscose smear uniformly and will
Extra viscose wiped clean；
Step F: bonding compacting is mutually cohered the linden veneer for being coated with viscose, and make the fiber side of adjacent layer veneer
It is formed to orthogonal gluing；
Step G: the formed plywood after bonding is integrally placed in sander and carries out polishing grinding from encouragement by whole polishing.
Preferably, easily there is cracking phenomena, the linden former material selected in the step A in glued board after molding in order to prevent
Material is A grade homogeneous materials, and the fibre dense of linden and uniform.
Preferably, in order to guarantee the compactness bonded, the abrasive end of the sander in the step B is coarse sand paper or more
Friction Sanding, and the sand paper can be replaced according to the intensity requirement of polishing.
Preferably, there is the phenomenon that veneer separation in glued board after prolonged use in order to prevent, glutinous in the step E
Glue is E1 grades of combined type viscoses, and viscose is applied to the front-back two-sided of veneer and carries out uniform smearing processing by applying patter.
Preferably, the insufficient pressure in compacting process in order to prevent, thus make occur gap between glued board, the step
Used compacting machine is oily hydrodynamic pressure type machine in compacting process in F, and the pressure coefficient of the hydraulic press is adjustable.
The beneficial effects of the present invention are: the preparation method design of the flame-retardant plywood is rationally, the linden selected in step A is former
Material is A grade homogeneous materials, and the fibre dense of linden and uniform, prevents glued board after molding from cracking phenomena easily occur,
The abrasive end of sander in step B is coarse sand paper Friction Sanding up and down, and the sand paper can according to the intensity requirement of polishing into
Row replacement guarantees the compactness of bonding, and the viscose in step E is E1 grades of combined type viscoses, and viscose is applied to the positive and negative of veneer
It is two-sided and carry out uniform smearing processing by applying patter, prevent glued board after prolonged use from the phenomenon that veneer separation occur,
Used compacting machine is oily hydrodynamic pressure type machine in compacting process in step F, and the pressure coefficient of the hydraulic press is adjustable,
The insufficient pressure in compacting process is prevented, to make occur gap between glued board.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
