Abstract
A method for making ply-bamboo includes such steps as providing bamboo strips, making parallel V-shaped slots, bleaching or high-temp desaccharifying, immersing in resin, laminating in mould, cold pressing, solidifying at 100-140 deg.C for 5-20 hr, natural cooling, and cutting by needed sizes.
Description
Technical field
The present invention relates to a kind of laminar product, particularly a kind of manufacture method of bamboo material stacked board.
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 stacked board 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 stacked board, is raw material with the bamboo wood, produces any surface finish, is suitable for the bamboo material stacked board as floor and the use of furniture panel.
A kind of manufacture method of bamboo material stacked board, comprise the making bamboo chip, bamboo chip is bleached or the high temperature desugar, and impregnation is handled, be pressed into bamboo side and be heating and curing, cut into bamboo material stacked board, it is characterized in that: at thickness is 2～3mm, width is to have a plurality of V-type grooves that are parallel to each other along its length on the surface of bamboo chip of 15～30mm, bamboo chip after routine bleaching or high temperature desugar and impregnation processing is hierarchically superimposed in mould, the well-thought-out plan side of under 20～70MPa high pressure, colding pressing, bamboo side cuts into required bamboo material stacked board with bamboo side after the cooling naturally 100～140 ℃ of following heat preservation solidification 5～20 hours, and its cut direction is surperficial vertical with bamboo chip; Be spaced apart 3～4mm between the V-type groove, the number of plies of laminated board 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 stacked board 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 stacked board 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-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 laminated board is 1.1g/cm
3
With prior art relatively, advantage of the present invention is: the bamboo material stacked board 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.
