Abstract
The invention discloses a kind of manufacture method of poplar flame-retardant plywood, comprise the following steps: a. moisture content lower than 12% board using poplar board surface uniform coat flame-retardant glue; B. row's flaggy folded formation straight sheet pile is carried out to blanket glued veneer and non-blanket glued veneer, with the coated straight sheet pile of preservative film, then position with screw mandrel clamping plate; C. straight sheet pile is sent into thermostatic chamber, rotation per hour screw mandrel pressurizes to straight sheet pile, makes straight sheet pile height be compressed to 5/6 of former height at 46 ~ 48 hours; During this period, per hour to preservative film surface sprinkling once; D. straight sheet pile is taken out from preservative film, pressure be 1.6 ~ 1.8Mpa, under temperature is the condition of 90 ~ 105 DEG C, first hot pressing 14 ~ 16 minutes, then pressure release is until the pressure of hot press is 0, again hot pressing 18 ~ 22 minutes again, obtain moisture content lower than 14% poplar flame-retardant plywood.The present invention does not need fermentation vat or pressurized tank, significantly improves output and reduces costs, giving full play to the price advantage of poplar, be conducive to manufacture in enormous quantities.
Description
Technical field
The present invention relates to glued board field, be specifically related to a kind of manufacture method of poplar flame-retardant plywood.
Background technology
Flame-retardant board to carry out after flame treatment, again with the glued board of adhesive gummed, generally comprising linden, Manchurian ash, birch, elm, poplar etc. with material to veneer.Wooden loose, the intensity difference of poplar, at present manufacturing flame-retardant plywood with poplar is first board using poplar board is placed in fermentation vat or pressurized tank soaks, make the hot repressing of flame-retardant glue infiltration board using poplar board shaping, while obtaining flame retardant effect, also improve the intensity of board using poplar board, make it reach the requirement of strength of glued board; Fermentation vat or pressurized tank is built because board using poplar board impregnation must rely on, the output of poplar flame-retardant plywood is restricted, and the construction cost of fermentation vat or pressurized tank is high, also the manufacturing cost of poplar flame-retardant plywood is caused to improve, counteract the price advantage of poplar itself to a great extent, cause poplar flame-retardant plywood to be difficult to large batch of manufacture.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of manufacture method of poplar flame-retardant plywood, and the impregnation that can solve existing poplar flame-retardant plywood relies on fermentation vat or pressurized tank, causes the problem that output is restricted and manufacturing cost is high.
The present invention is achieved through the following technical solutions:
A manufacture method for poplar flame-retardant plywood, comprises the following steps:
A. moisture content lower than 12% board using poplar board surface uniform coat flame-retardant glue, the consumption of described flame-retardant glue is 1.3 ~ 1.4 Kilograms Per Square Meters;
B. adopt glued board row plate technique to carry out row's flaggy to blanket glued veneer and non-blanket glued veneer and be stacked to 1.6 ~ 2 meters high formation straight sheet piles, with the coated straight sheet pile of preservative film, then position with screw mandrel clamping plate;
C. straight sheet pile is sent into the thermostatic chamber that temperature is 9 ~ 11 DEG C, rotation per hour screw mandrel pressurizes to straight sheet pile, makes straight sheet pile height be compressed to 5/6 of former height at 46 ~ 48 hours; During this period, per hour to preservative film surface sprinkling once, preservative film surface is kept wet;
D. straight sheet pile is taken out from preservative film, pressure be 1.6 ~ 1.8Mpa, under temperature is the condition of 90 ~ 105 DEG C, first hot pressing 14 ~ 16 minutes, then release is until the pressure of hot press is 0, again hot pressing 18 ~ 22 minutes again, obtain moisture content lower than 14% poplar flame-retardant plywood.
Further scheme of the present invention is, step a flame-retardant glue used is mixed by the material of following percentage by weight: APP 5 ~ 7%, tricresyl phosphate 3 ~ 5%, melamine phosphate 15 ~ 17%, and all the other are environmental protection urea-formaldehyde glue.
The present invention's advantage is compared with prior art:
One, glued board being arranged flaggy poststack adopts preservative film coated, colds pressing, does not need fermentation vat or pressurized tank, significantly improve output and reduce costs, giving full play to the price advantage of poplar, be conducive to manufacture in enormous quantities with screw mandrel clamping plate;
Two, first hot pressing release venting again, and then hot pressing again, significantly shorten the time of hot pressing processing, also significantly reduce the energy consumption of hot pressing processing, reduce further the manufacturing cost of poplar flame-retardant plywood.
Detailed description of the invention
A manufacture method for poplar flame-retardant plywood, comprises the following steps:
A. moisture content lower than 12% board using poplar board surface uniform coat flame-retardant glue, the consumption of described flame-retardant glue is 1.3 ~ 1.4 Kilograms Per Square Meters, described flame-retardant glue is mixed by the material of following percentage by weight: APP 5 ~ 7%, tricresyl phosphate 3 ~ 5%, melamine phosphate 15 ~ 17%, all the other are environmental protection urea-formaldehyde glue;
B. adopt glued board row plate technique to carry out row's flaggy to blanket glued veneer and non-blanket glued veneer and be stacked to 1.6 ~ 2 meters high formation straight sheet piles, with the coated straight sheet pile of preservative film, then position with screw mandrel clamping plate;
C. straight sheet pile is sent into the thermostatic chamber that temperature is 9 ~ 11 DEG C, rotation per hour screw mandrel pressurizes to straight sheet pile, makes straight sheet pile height be compressed to 5/6 of former height at 46 ~ 48 hours, makes straight sheet pile under a steady pressure, be conducive to the infiltration of flame-retardant glue; During this period, per hourly to preservative film surface sprinkling once preservative film surface is kept wet, prevent the straight sheet pile moisture evaporation in preservative film so that flame-retardant glue premature cure;
D. straight sheet pile is taken out from preservative film, pressure be 1.6 ~ 1.8Mpa, under temperature is the condition of 90 ~ 105 DEG C, first hot pressing 14 ~ 16 minutes, then release is until the pressure of hot press is 0, steam in sheet material is fully volatilized, again hot pressing 18 ~ 22 minutes again, obtain moisture content lower than 14% poplar flame-retardant plywood.
