Description
Technical field
Bamboo reinforcement net made of bamboo wood and bamboo and wood processing remaining material or straw etc. particles heat are utilized the present invention relates to a kind of
The manufacturing method of molded composite board of small pieces of bamboo reinforcement, belongs to field of plate manufacture.
Background technology
Bamboo wood has the advantages that intensity is big, hardness is high, resourceful and can replace timber, and bamboo branch item, bamboo processing are surplus
The particles such as remaining particle or straw have the characteristics that fillibility is good, dilatancy is uniform, sound-insulating heat-insulation property is good, thus the two is being made
It is used widely in board industry.The wood-based plate produced currently with bamboo wood, particle is had by its structure and processing technology point：It is glued
Plate class, laminate class and flakeboard class.Bamboo wood is split gluing after piece, is hot pressed into plate by the first two kind plank using bamboo wood as primary raw material
Material, intensity, hardness are preferable, but that there are consumption of raw materials amounts is big, processing request is high, interiors of products gap is more, density is small, thickness error
The defects of big, the number of turnover is less when being used as building template, and surface is rougher, tends not to meet building surface
Flatness requirement.The latter is cold-pressed or is hot pressed into plank using particle as primary raw material, by particle, and bamboo wood consumption is few, and cost is relatively low, production
Product density is big, and flatness is high, but there are the smaller defect of product mechanical strength, cannot meet as building template, truck board and
The performance requirement of the larger bamboo wood board of other loads, reuse rate are low.The bamboo wood board of existing method manufacture, density and strong
Degree is difficult to improve again, and thickness error phenomenon is difficult to avoid that.
Invention content
The technical problem to be solved in the present invention and the technical assignment of proposition are to overcome defect existing for existing product, provide one
Kind high intensity, the manufacturing method of high density, the good composite board of small pieces of bamboo reinforcement of flatness.It is to utilize bamboo reinforcement net made of bamboo wood
It is produced full as raw material by improving plate construction and manufacturing method with the bamboo and wood processing particles such as remaining material or straw
Foot is as building template, the composite board of small pieces of bamboo reinforcement of truck board and the larger bamboo composite board material performance requirement of other loads.
To achieve the above object, the present invention is implemented by the following technical solutions：
A kind of manufacturing method of composite board of small pieces of bamboo reinforcement, method and step are as follows：
Appropriate bamboo wood and bamboo branch item, bamboo and wood processing remaining material or straw are chosen as raw material；
Bamboo branch item or bamboo and wood processing remaining material or straw are ground into particle by 1-1；
1-2 particles stack ageing, and particle is placed in the dry machine of dried disinfecting carbon, the dry machine heating of dried disinfecting carbon by dry carbonization
Temperature be 160-190 DEG C, 2-4 hours heating times, particle carbonization, carbonizing degree be 5%-30%；
It is 0.5cm that 1-3, which selects sieve pore specification, the sieve of 0.5~1cm specifications, and particle is sieved, is graded heap by thickness
It puts, is weighed, glued, resin added is 25~35%；
Bamboo wood hacking is split the thin bamboo strip by 2-1, and drying to moisture content is 8~12%；
2-2 bamboos slight predrying after gluing；
2-3, which slights bamboo, is woven into bamboo reinforcement net；
Coarse particles are filled in bamboo reinforcement net areola by 3-1 assemblies, and disentegrated particles are covered in bamboo reinforcement is online, lower surface；
It is pressed into blank in advance under 3-2 room temperature；
4-1 preset backing plates on hot press, preset fixed width on backing plate determine slab；
Blank is put into fixed width, determines the space that slab surrounds by 4-2 hot pressing, and upper and lower surface lays finish coat, carries out hot pressing,
Hot pressing temperature is 100~160 DEG C, and pressure is 10~60Mpa, is pressed into composite board of small pieces of bamboo reinforcement.
Preferably, it is 0.5~4.0mm that the bamboo, which slights thickness, width is 0.5~2.5mm, and track and column braiding is at groined type bamboo
Muscle net, 5 × 5~250 × 250mm of sizing grid.
Preferably, described group of blank process is with finish coat, bamboo mat or wood chip, particle, groined type bamboo reinforcement net, particle, bamboo mat
Or the sequence of wood chip, finishing material lays raw material.
Preferably, one or more layers can be arranged in the groined type bamboo reinforcement net in described group of blank process.
Preferably, the glue kind of the gluing is one kind of modified phenolic glue or modified urea-formaldehyde glue, waterproof is added in when gluing
Agent, waterproofing agent dosage are 3~5%.
The beneficial effects of the invention are as follows：
The present invention uses the particle of abundance, reduces production cost, makes to be taken as fuel wood or discarded raw material in the past
It re-uses, substantially increases the comprehensive utilization ratio of resource；It is reasonable in design.Due to utilizing bamboo wood bamboo reinforcement net and particle easily
In conjunction with characteristic, manufactured plate product has been compatible with the good characteristic of bamboo plywood and flakeboard, has high intensity, high hard
The features such as degree, density is big, high-flatness, physico-mechanical properties and exterior quality are good, high as building template reuse rate,
After being first cold-pressed hot pressing process reduce " bubblings " phenomenon of bamboo board class product, product qualification rate height, plank thickness is uniform.
