Description
Technical field
The present invention relates to a kind of floor, particularly relate to a kind of bamboo fibre bar composite floor board.
Background technology
China is bamboo big country, and bamboo yield is big, and has long bamboo utilization history, and bamboo product enriches.Bamboo wood has
The advantage that flexible is good, intensity is big, is commercially made into the raw material of indoor floor, outdoor flooring and furniture etc..But
Bamboo wood is contained within substantial amounts of sugar, protein, and inclusions is enriched, and is therefore highly prone to infringement and the corrosion of bamboo corruption fungus；Wooden
Element, hemicellulose and the existence of cellulose, make the poor dimensional stability of Recombined bamboo material.
For solving above-mentioned technical problem, prior art CN204876310U(2015-12-16) in disclose a kind of carbon
Changing bamboo and woods fiber bamboo silk composite concrete board, but this product is either from apparent, or from using impression, process time all
Need to improve.

Comparative example
The processing method of composite plate, comprises the steps:
Step one: select materials
The Phyllostachys pubescens Mazei ex H.de Lebaie leftover pieces produced during bamboo processing, are divided into the bamboo silk of fine strip shape, and scrappy bamboo section, and selecting materials is exactly by bamboo
Silk, bamboo section sort out, and then bamboo silk and bamboo section are carried out hydrothermal treatment consists, and described hydrothermal treatment consists is exactly 90 by bamboo silk and bamboo section
～steaming and decocting 3～5 hours at a temperature of 160 DEG C, the bamboo wood moisture control after process is between 40%～60%, and it is main
Effect is insect protected, mildew-resistant process, reduces the hardness of raw material；Increase the pliability of raw material, reduce the cured matter of bamboo material surface, increase gluing
Intensity；After hydrothermal treatment consists, bamboo silk is selected, bamboo section is chipped, process well-thought-out plan particle；
Step 2: processing bamboo silk
By length coarse and fine separation, bamboo silk being gone out all size, lashes bunchy, what length thickness was close is used for processing dimension
Bamboo silk layer；Bundles of bamboo silk will be lashed be put into drying room and be dried so that it is moisture content is 10～15%, and this bamboo silk is true qualities；
Carry out carbonization in putting carbide furnace into through the bamboo silk of above-mentioned dried, control temperature and time and can control carbonization
In various degree, the bamboo silk after carbonization is light brown or dark-brown；
Bamboo silk urea glue, phenol glue or melamine glue after drying, carbonization carry out impregnation, then are dried, and gel content accounts for
The 2%～6% of raw material gross weight, moisture content is 8%～15%；
Step 3: processing bamboo particle
Bamboo particle being put into drying room be dried so that it is moisture content is 10～15%, bamboo particle uses spraying applications method, passes through
Urea glue, phenol glue or tripolycyanamide glue are sprayed onto the surface of particle with mist by the glue spraying hole of glue mixer upper cover, pass through
The stirring of agitator makes glue progressively tend to being uniformly distributed on particle surface, and gel content accounts for the 8%～15% of bamboo particle gross weight,
Bamboo particle after applying glue was placed on about room temperature lower half an hour；
Step 4: processing bamboo silk composite plate
Volume and densimeter according to bamboo silk composite plate to be made calculate the bamboo silk weight needed for every layer of bamboo silk layer and every layer of bamboo particle
Bamboo particle weight needed for Ceng is also weighed, and makes removable boxlike or frame mold, and monolayer bamboo silk material is loaded mold
In, at one layer of upper berth of monolayer bamboo silk material bamboo particle, bamboo particle repaving one layer of bamboo silk material, bamboo silk layer is staggered with bamboo particle layer folded
Put, somewhat apply vibration and make bamboo silk material and bamboo particle load closely knit formation bamboo silk composite plate just base in mold, tear mold open, more right
The just base binding of bamboo silk composite plate is fixing, and the thickness of the band that binding is used is preferably 0.3～0.5mm；
Being put into by bamboo silk composite plate just base and carry out hot-press solidifying molding in hot press, temperature controls at 85～180 DEG C, the time 6
～20 minutes, bamboo silk composite plate just base is the thickest, and required time is the longest, otherwise bamboo silk composite plate just base is the thinnest, and required time is more
Short, to remove bundling belt, the bamboo silk composite plate dislocation after molding is carried out heat cure in greenhouse, temperature controls 150～200
DEG C, the time is 3～8 hours；
Step 5: saw limit, sanding
Burr bamboo silk composite plate after hot pressing after cooling, is sawn into the bamboo silk composite plate of all size, then carries out sanding process.
