Abstract
A method for making the laminated bamboo product includes such steps as pretreating bamboo strips, laminating, binding and laying it on the bench of cold press, pressing from both ends, solidifying at 100-140 deg.C for 2-3 hr, natural cooling and planning surface layer.
Description
Technical field
The present invention relates to a kind of laminar product, particularly a kind of manufacture method of bamboo material layered product.
Background technology
Bamboo is a kind of pure natural material, and growth is quick, and its fiber is hard, and density is big, and moisture content is few, and wood substituted by bamboo is made sheet material becomes a kind of fashion.With the bamboo wood is raw material, and the sheet material of making by bamboo chip lamination hot pressing mode is a kind of glued board.Existing bamboo material layered product is because rough surface mainly as cement formwork, and can not be used as the floor, or making furniture panel.Chinese patent CN 99117809.2 provides a kind of method of recombining bamboo material into reinforced shapes, mao bamboon is split into the bamboo silk, impregnation is adorned mould after drying, suppress and be solidified into section bar through high pressure again, because the bamboo silk behind the dress mould is difficult to proper alignment, existence interlocks unavoidable each other, compacting also is solidified into section bar, this section bar surface still owes smooth, has many atypic grooves to exist, and influences outward appearance.
Summary of the invention
The object of the present invention is to provide a kind of manufacture method of bamboo material layered product, is raw material with the bamboo wood, produces any surface finish, is suitable for the bamboo material layered product as floor and the use of furniture panel.
A kind of manufacture method of bamboo material layered product, comprise and make bamboo chip, bamboo chip is bleached or high temperature desugar and impregnation processing, bamboo chip after handling is hierarchically superimposed and be pressed into blanket, blanket digs into bamboo material layered product behind hot setting, it is characterized in that: add wrapping after the bamboo chip layering of handling is superimposed, bamboo chip group after the wrapping is sidelong on the workbench of cold press, the bamboo chip group is 15～20MPa under two-way to be pressed into one from both sides at pressure by cold press, 100～140 ℃ of following heat preservation solidification 2～3 hours, the rim charge of shooting off after the cooling was naturally made bamboo material layered product afterwards.The bamboo chip of being made by mao bamboon is the bamboo chip of removing behind extexine and the endosexine, and its thickness is 2～3mm, and width is 15～30mm, and length is 1500～2000mm, and its number of plies of bamboo material layered product is 50～80 layers.
Used bamboo chip is the bamboo chip after the bamboo chip that extexine and endosexine are difficult for impregnation is removed, and the density of this bamboo chip is 0.6～0.7g/cm
3, the bamboo chip bleaching is after bamboo chip is flooded in sodium hydroxide solution, places the hydrogenperoxide steam generator bleaching that adds little acetic acid to handle, concentration of hydrogen peroxide is 2% in the solution, acetate concentration is 0.05%, the bamboo chip after bleaching, and the bamboo material layered product of making is white plate.The desugar of bamboo chip high temperature is that bamboo chip is placed container, and feeding pressure is the water vapour of 0.2～0.27Mpa, takes out after spending 1～3 hour, and this moment, bamboo chip became brownly, and the bamboo material layered product of making also is brown plate.The used impregnation of bamboo chip is a kind of in phenol glue, cyanurotriamide modified urea-formaldehyde glue, resorcinol one glutol mixture, the isocyanate adhesive, and resin added is 15～20% of a bamboo chip weight, and its moisture content of dried bamboo chip is not more than 15%.Described bamboo chip bleaching, high temperature desugar, impregnation are known technology.The bamboo wood density of layered article is 1.1g/cm
3
With prior art relatively, advantage of the present invention is: the bamboo material layered product plate face of making is smooth pure white, perhaps is brown, the plate face is vertical with the bamboo chip surface, and no ring vestige is durable in use, not yielding, performance is better than existing bamboo wood sheet material, is suitable for as floor and furniture panel.

Fig. 3 is the structure chart of bamboo material layered product.
The specific embodiment
Mao bamboon is processed into bamboo chip 1, and the thickness of bamboo chip is 2mm, and width is 15mm, and through the bleaching of routine with soak urea-formaldehyde glue and handle, this moment, the gel content of bamboo chip was 15% with above-mentioned bamboo chip, and moisture content is not more than 15%.After the bamboo chip layering after the above-mentioned processing is superimposed, add wrapping, bamboo chip group after the wrapping is sidelong on the workbench 2 of cold press, the bamboo chip group is 15MPa under two-way to be pressed into one from both sides at pressure by cold press 3,100 ℃ of following heat preservation solidification 2 hours, the rim charge of shooting off after the cooling was naturally made bamboo material layered product 4 afterwards, and the bamboo chip number of plies of layered article is 80 layers, the bamboo material layered product 4 plate faces of making are smooth pure white, the plate face does not have the ring vestige, and is durable in use, not yielding.
Embodiment 2
Mao bamboon is processed into bamboo chip, and the thickness of bamboo chip is 3mm, and width is 30mm, and through the bleaching of routine with soak phenol glue and handle, this moment, the gel content of bamboo chip was 20% with above-mentioned bamboo chip, and moisture content is not more than 15%.After the bamboo chip layering after the above-mentioned processing is superimposed, add wrapping, bamboo chip group after the wrapping is sidelong on the workbench 2 of cold press, the bamboo chip group is 20MPa under two-way to be pressed into one from both sides at pressure by cold press 3, afterwards 140 ℃ of following heat preservation solidification 3 hours, naturally the rim charge of shooting off after the cooling is made bamboo material layered product 4, the bamboo chip number of plies of layered article is 50 layers, and the bamboo material layered product plate face of making is smooth pure white.
Embodiment 3
Mao bamboon is processed into bamboo chip, and the thickness of bamboo chip is 2.5mm, and width is 20mm, above-mentioned bamboo chip is carried out the high temperature desugar handle, bamboo chip is placed container, feeding pressure is the water vapour of 0.2Mpa, take out after spending 2 hours, this moment, bamboo chip became brownly, handled through impregnation again.After the bamboo chip layering after the above-mentioned processing is superimposed, add wrapping, bamboo chip group after the wrapping is sidelong on the workbench 2 of cold press, the bamboo chip group is 20MPa under two-way to be pressed into one from both sides at pressure by cold press 3, afterwards 120 ℃ of following heat preservation solidification 2 hours, naturally the rim charge of shooting off after the cooling is made bamboo material layered product 4, the bamboo chip number of plies of layered article is 60 layers, and the bamboo material layered product of making is brown plate.
