Abstract
A method for manufacturing the high-strength ply-bamboo includes such steps as preparing bamboo strips, bamboo mat and bamboo curtain, baking (preheating, evaporating and cooling), immersing in adhesive, baking (preheating, evaporating and cooling), laminating, hot pressing and shaping. It has high strength and high weatherability.
Description
Technical field
The invention belongs to the Manufacturing Technology of Plywood technical field, specifically, relate to a kind of manufacture method that is used as the bamboo plywood with high strength of container bottom board, auto carriage board and top-grade building template
Background technology
At present, the container bottom board on the market, auto carriage board and top-grade building template adopt full wood plywood mostly; But timber resources is greatly limited, one: the growth cycle of timber is long, needs at least just can cut down usefulness more than 30 years; Its two: countries in the world are for the needs of environmental protection and maintaining ecological balance, launch respectively limit and cut down even prohibit the policy of cutting down, and the wood supply amount is cut down greatly, cause price to rise violently thereupon.A kind of composite bamboo-timber structure glued board with bamboo wood instead of part timber appearred on the market over past ten years, but because bamboo wood is different with timber its MOR, internal stress and water absorption rate under same environment for use, quality problems in use appear easily, and the ratio that bamboo wood occupies is less, can't fundamentally solve the problem of timber resource shortage, for this reason, the glued board of full bamboo wood structure just arises at the historic moment.
At notification number is CN87100368, and the day for announcing is on August 24th, 1988, and name is called and discloses a kind of process that mao bamboon is made bamboo plywood by operations such as softening flattenings in the Chinese invention patent of " bamboo plywood manufacture method ".This method adopts the pressurization flattening process, is easy to generate the crack, thereby influences bonding strength; And do not carry out the position sorting during former bamboo blanking, because the bamboo wood density difference of different parts, the heterogeneity any combination thereof can cause thickness deviation big.The present invention exists softening flattening process route long, and energy resource consumption is big, shortcomings such as cost height.At notification number is CN2161443, the day for announcing is on April 13rd, 1994, name is called the manufacture method that also discloses a kind of bamboo plywood in the Chinese invention patent of " container bamboo plywood ", it is to dry behind the inner skin of a bamboo stem impregnation with certain width and thickness, form by HTHP curing after mould is adorned in the direction layering in length and breadth, the part process is limit by manual operations in whole process, thereby complex process, small scale, difficult quality is guaranteed, the thickness deviation of product is big, the section structure level is not clear, and the space is big, and density unevenness is even, cause the mechanical property instability, stock utilization is low.
Summary of the invention
The manufacture method that the purpose of this invention is to provide a kind of bamboo plywood with high strength, with the bamboo plywood intensity height that this method makes, good weatherability, every performance indications all are better than like product on the market.
The manufacture method of bamboo plywood with high strength of the present invention comprises the following steps:
(1) preparation of raw material bamboo sheet, bamboo mat and bamboo curtain splint, wherein bamboo chip be with fresh bamboo wood through blanking, broken bamboo, go green grass or young crops, go joint and layering machine burst to form; Bamboo mat is to form by braiding with bamboo chip; Bamboo curtain splint is that back side by side the wearing even with cotton rope of bamboo chip formed;
(2) oven dry before the glue, it is online that required raw material evenly are layered on material, and sending into dry kiln drying to moisture content is 8～16%, and its process is divided three phases: warm-up phase was preheating to 120～150 ℃ with raw material from normal temperature with 5～30 minutes; Evaporation stage is controlled at temperature between 120～150 ℃, is incubated 20～150 minutes, with transpiring moisture; Cooling stage, insulating process was cooled to raw material below 60 ℃ from evaporating temperature with 5～30 minutes after finishing;
(3) impregnation, with oven dry before the glue and be cooled to raw material below 40 ℃ to immerse solid content fully be that the impregnation time is 4～6 minutes in 20～50% the phenolic resins glue, impregnation resin content is 70～150Kg/m
3, taking-up drained 60～80 minutes, till rubber drop-free liquid;
(4) dry behind the glue, it is online that required raw material evenly are layered on material, and sending into dry kiln drying to moisture content is 10～14%, and its process is divided three phases: warm-up phase was preheating to 65～95 ℃ with raw material from normal temperature with 5～30 minutes; Evaporation stage is controlled at temperature between 65～95 ℃, is incubated 10～60 minutes, with transpiring moisture; Cooling stage, insulating process was cooled to raw material below 40 ℃ from evaporating temperature with 5～20 minutes after finishing;
(5) assembly according to the used raw-material difference of glued board surface layer, sandwich layer and backing layer, is selected one or both or three kinds in bamboo chip, bamboo mat, the bamboo curtain splint to make up to feed intake and is mated formation, and forms the gummed slab of sandwich construction;
(6) the glued board slab is sent in hot pressing when heating platen is lower than 65 ℃, its process is divided four-stage: the temperature rise period, pressure is 0.5～2Mpa, 10～25 minutes consuming time, slab is risen to 130～160 ℃; Holding stage, pressure are 1.5～3Mpa, are incubated 10～30 minutes; Cooling stage, pressure are 1.5～3Mpa, 10～25 minutes consuming time, blanket are cooled to below 65 ℃; After release, blanket are cooled to below 65 ℃, pressure progressively is released into zero, carries out release;
(7) the glued board finished product of certain size specification is processed in moulding as requested.
The surface layer of glued board, sandwich layer and backing layer all adopt bamboo wood among the present invention, and select one or both or three kinds in bamboo chip, bamboo mat, three kinds of forms of bamboo curtain splint to make up the assembly of mating formation that feeds intake, and are hot pressed into the glued board of sandwich construction.Bamboo wood can be selected the cizu that spreads all over China southwest, Mianzhu etc. for use; Adopt broken bamboo machine to break bamboo, production efficiency height, steady quality.Go green grass or young crops after the bamboo section breaks, remove joint (reservation inner membrance); In order to improve bonding strength, when going to save, tabasheer is scratched with special pressure roller, smooth, the no recovery stress of gained bamboo chip, the gummed area increases greatly; Improve the efficient of subsequent step, saved a large amount of manpower and materials.The process conditions such as time, temperature and pressure in strict each stage of control in oven dry and the hot pressing process make the every performance indications of the glued board that makes all can satisfy and exceed corresponding industry standard behind oven dry before glue, impregnation, the glue.
The manufacture craft of glued board of the present invention is simple, the stock utilization height, and most of operation can realize mechanized operation, every performance indications all are higher than the market like product; Have that intensity height, good springiness, weatherability are strong, anticorrosive, characteristics such as anti-flaming thermal-insulation, cheap, aboundresources, can be widely used in fields such as container bottom board, auto carriage board and top-grade building template.
