Abstract
The present invention is timber and bamboo material processing and utilizing method. The present invention features that the timber-bamboo section bar is produced through the following steps: eliminating green part of bamboo, eliminating bark of timber, mechanically rolling into bamboo and timber sheet with glue content of 3-5 %, heat treatment, drying, gluing, ageing, compounding and molding and high temperature hot pressing to solidify and to form the section bar. The present invention well combines timber and bamboo material, and has less damage to their fiber structure and low glue consumption.
Description
Technical field
The present invention relates to a kind of method of bamboo wood and timber being carried out processing and utilization.
Background technology
Merely timber or bamboo wood being carried out method for processing has a lot, the patent No. is the method that 99117809.2 Chinese invention patent discloses a kind of recombining bamboo material into reinforced shapes, it is split into the bamboo silk with mao bamboon, and impregnation dress mould is suppressed and curing molding through high pressure more after drying.The method has improved the utilization rate to bamboo wood, the good stability of section bar, but have following defective: 1) raw material is full bamboo all generally, and it is too single to draw materials, and raw material supply is nervous; Can produce a large amount of waste materials when 2) mao bamboon is cooked the well-thought-out plan silk, comprise dust, particle, part and fracture of wire, reduce utilization ratio of raw materials; 3) fiber elongation method is handled bamboo wood, makes the fibre structure of bamboo wood be subjected to destroying largely, will use the glue of more amount in the regrouping process, and cost is high and strengthened the density (proportion) of section bar.
Summary of the invention
The technical assignment of technical problem to be solved by this invention and proposition is to overcome the defective that above-mentioned prior art exists, and a kind of manufacture method of bamboo-wood composite section bar is provided, and makes the utilization rate of material higher, and it is more extensive to draw materials; Utilize the characteristics of bamboo timber matter to avoid when compacting, destroying the fibre structure of material.
The technical solution adopted in the present invention is as follows: the manufacture method of bamboo-wood composite section bar, it is characterized in that bamboo wood is gone green grass or young crops, timber peeling, through cal rolling well-thought-out plan matter and wooden base sheet, the base sheet is through heat treatment, drying, gluing, ageing, compound assembly dress mould, the gel content of base sheet is 3-5%, changes into section bar after elevated temperature heat presses solidly.The product that the present invention makes has both performances of bamboo wood concurrently, and density is (1.05-1.15g/cm suitably
3), and utilize the characteristics of both materials, and make material bonding tightr, in pressing process, can not destroy the fibre structure of material basically, spread is few.The present invention adopts the cal rolling method, and technology is simple, and adding does not have the generation of bamboo wood powder dirt man-hour, raw material is fully exploited, and makes drawing materials of bamboo wood and timber more extensive.
The manufacture method of described bamboo-wood composite section bar, carrying out Fixed width with the dull and stereotyped clamping of the mould that leads to vapour, water blank before high temperature hot pressing decides thick, also can reach thick surely requirement by regulating pressure size and proportion scale, length≤the 2.5m of control section bar, width≤1.3m, thickness≤11cm makes the breadth of product big, easy to use and processing.
The manufacture method of described bamboo-wood composite section bar, bamboo wood is selected the leftover pieces after mao bamboon, assorted bamboo, small-bore bamboo or the bamboo processing for use, timber can be selected willow, willow or the timber leftover pieces after processing for use, this is the advantage that adopts compaction technology to bring, make and draw materials more extensively, solved the raw material bottleneck problem effectively.
The manufacture method of described bamboo-wood composite section bar, used glue are water-fast glue, and this water-fast glue is selected modified phenolic, modified cyanurotriamide glue or soluble polyurethane for use.
The manufacture method of described bamboo-wood composite section bar, the base layer that is used for composite material can be simple bamboo matter base layer or wooden base layer, also can be that bamboo wood mixes the base layer, each base layer is pressed the native texture order and is arranged, and helps eliminating internal stress, makes product be difficult for sticking up, splitting.
The manufacture method of described bamboo-wood composite section bar, section bar is composited by three layers, and upper and lower superficial layer is a bamboo matter base layer, and sandwich layer is wooden base layer, guarantees the intensity on section bar surface preferably, and the bamboo texture of section bar is clear naturally.
Technology of the present invention is simple, utilizes the combination of bamboo wood and timber, has following beneficial effect: 1) raw material can adopt source abundant, cheap assorted bamboo and willow, and the residue after the processing of bamboo timber, has solved the bottleneck problem of existing raw material effectively; 2) do not destroy the intrinsic fibre structure of raw material basically, make the cemented surface of storeroom little, glue consumption is few; 3) seldom produce dust, particle and part fracture of wire, utilization ratio of raw materials is higher; 4) product that makes is difficult for sticking up, splitting, and surface property is better.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a schematic flow sheet of the present invention.
The specific embodiment
As shown in the figure, the manufacture process of bamboo-wood composite section bar is as follows:
Raw material is handled: bamboo wood, timber is sawed-off by specification, and bamboo wood goes green grass or young crops then, the timber peeling.
Roll: raw material is pressed into the base sheet that inequal cleavage stitches, and thickness is 2-5mm, and width is 2-30mm, and length is random.
The heat treatment of base sheet, drying, gluing, ageing: heat treatment is the base sheet to be soaked in hot-tub or logical with steam, to reach purpose softening, anticorrosion, mildew-resistant, make moisture content be controlled at 8-10% when dry, sizing material adopts the phenol glue of modification, the gel content of base sheet is controlled at 3.5-4.5%, ageing is meant places a period of time to the raw material after the gluing, makes glue more even in material.
Assembly: the compound integrated assembly of bamboo wood, upper and lower superficial layer is a bamboo matter base sheet, and sandwich layer is wooden base sheet, and each layer pressed the texture order and arranged.
Fixed thick Fixed width: with leading to width and the thickness that the upper and lower two hot-die flat boards that steam G﹠W fix the base sheet, the length≤2.5m of section bar, width≤1.3m, thickness≤11cm.
High temperature hot pressing is also solidified: temperature is 110-120 ℃, and unit pressure is 2-9mpa/cm
