Abstract
The invention relates to the bamboo wood processing, particularly to a method for producing a bamboo-wood three-layer composite floor. The invention is realized by the following technical scheme: the method for producing the bamboo-wood three-layer composite floor comprises in sequence the following steps of: (1) preparing raw materials; (2) hacking and roughly milling; (3) carbonizing; (4) adjusting water content; (5) using a wood board processing method; (6) gluing and assembling; (7) hotly pressing; (8) slotting for arranging tenons; (9) sanding; and (10) painting. The bamboo-wood composite floor produced by the method has simple and unsophisticated color and luster and is economical, practical and difficult to deform along with better dimensional stability.
Description
Technical field
the present invention relates to the processing of bamboo wood, the production method of three layers of composite floor board of particularly a kind of bamboo wood.
Background technology
China belongs to Shaolin country, has forest reserves per capita less than 9.1m
3
, the timber supply and demand is very nervous.Along with the rise of interior design, the wood floors demand sharply increases in recent years, and the manufacturing of China's wood floors depends on from ground imports such as Southeast Asia, Africa with material always for a long time.Yet, along with the whole world in recent years to the attention of ecological environment, make each timber exported country reduce one after another and limited the log outlet; Caused wood floors there is lack of raw materials with and the rise of price, impel the consumer when choosing the floor, to pay the utmost attention to the rational more non-solid wood class of price floor, like the bamboo floor; These reasons all will force the lasting contraction of solid wood class floor occupation rate of market, in the huge home decoration consumption market of China, and the floor of non-solid wood class, particularly bamboo floor will show more and more actively.
China is the abundantest country of bamboo resource in the world, and wherein industrialized utilization is worth the highest mao bamboon and surpasses 300hm
2
, account for 90% of the total mao bamboo woods area in the world; Bamboo wood is a kind of resource of easy regeneration, and growth is rapid, can cut down utilization in 4 to 5 years, and its material-structure intensity generally is higher than timber; In addition, the common texture that has aesthetic feeling of general bamboo wood, elegant color and luster, characteristic such as cool in summer and warm in winter all make it be well suited for being used for the floor and make; Therefore, comprehensive exploitation bamboo industry is significant, and along with the development of real estate, the construction material that is used for mating formation on ground is also developed, and people change present solid wooden floor board, bamboo floor etc. into from original tile floor; Though the tile floor low price is but not high-grade; Though solid wooden floor board is elegant in appearance, durable in use, cost is expensive.
Summary of the invention
the purpose of this invention is to provide the production method of three layers of composite floor board of a kind of bamboo wood, and the bamboo compound floor of using this method preparation is elegant in appearance, economical and practical, and has dimensional stability preferably, and is not yielding.
Above-mentioned technical purpose of the present invention is achieved through following technical scheme: the production method of three layers of composite floor board of a kind of bamboo wood, and it comprises above step successively:
(1) preparation of former material: select the bamboo wood of growth 4-6, according to the length of demand, sawed-off;
(2) hack and rough mill: bright bamboo is broken in flakes, bright bamboo chip is rough milled with milling tool;
(3) charing: charing is to place in the charing case rough milling bamboo chip, and the temperature in the control charing case is 160 ℃-200 ℃, and humidity is 80% to 85%, keeps 5-7h;
(4) moisture content adjustment: the bamboo chip after the charing is carried out constant temperature drying in 70-90 ℃ drying room, make moisture content be adjusted into 8-9%;
(5) plank processing method: be with round log saw blade, oven dry, adjustable cast iron planes;
(6) applying glue assembly: this bamboo compound floor divides three layers; What the top layer was used is bamboo chip, and what middle level or bottom were used is solid wood plate or fiberboard, and the bamboo chip of choosing, solid wood plate or fiberboard are coated phenolic resin glue or urea acid resin glue respectively; Be spliced into plate then, send into moulding in the hot press;
(7) hot pressing: be placed on the sheet material blank on the hot press, control heating platen temperature is 110-120 ℃, and heating platen contacts with sheet material, thereby carries out preheating, and be 10-15min preheating time; Controlled pressure is 1.5-1.8MPa again, and control heating platen temperature is 150-160 ℃, heat-insulation pressure keeping 30min～120min; Thereby with the sheet material hot-press solidifying, the blanket square stock is processed in cold moudling then;
(8) fluting cloth tenon: blanket is refining on four sides, and with four side moulder fluting cloth tenon, bamboo-wood plyboard processes with thicknesser or four side moulder then;
(9) sand milling: the bamboo-wood plyboard of milling moulding is carried out sand milling with sand mill scrape;
(10) japanning: the finished product after sand milling is scraped is gone up earlier and is drenched priming paint, drenches finish paint then.
in sum; The present invention has following beneficial effect: the bamboo compound floor color and luster that adopts this method to produce is simple and unsophisticated; Economical and practical, three layers of bamboo wood that the bamboo compound floor structure is big with intensity, hardness is high are as skin-material, with the combining structure of timber as core and bottom surface material; Strengthen self regulating that system's internal stress changes effectively, overcome problems such as single bamboo floor and solid wooden floor board size be unstable, yielding to a great extent; Three layers of bamboo compound floor sandwich layer and bottom have used timber, have strengthened the elasticity on floor, have fabulous feel and service life.
