Zero public hazards glueless bamboo matter and/or wooden recombined material and its manufacturing method

Technical field

The invention belongs to recombined material technical fields, are related to no adhesive, environment-friendly type, resource-effective structural material, especially It is to provide a kind of zero public hazards glueless bamboo matter and/or wooden recombined material and its manufacturing method.

Background technique

China is bamboo resource country the most abundant in the world.It is in recent years, gradually deficient with world's timber resources, Rationally and effectively become more and more important using timber and bamboo timber resource.

The approach that bamboo and wood materials rationally utilize be exactly material recombination and it is compound.

In the prior art, the main Recombined bamboo technology for the fields such as building, decorating has:

(1) thin bamboo strips used for weaving recombinant technique: being processed into thick bamboo for bamboo processing and slight, individually, or along with the wooden beam, suitable of comb solution The veneer strip of amount, drying are formed to moisture content 8~15% with phenolic resin gluing.

(2) bamboo fiber reinforced composite material manufacturing technology: by bamboo wood discongest into it is elongated, be cross-linked with each other and keep fiber former There are the loose reticular fibre beam of arrangement mode, then the board-like material made of hot pressing after drying, sizing, assembly molding.

(3) bamboo side's Recombined bamboo technology: hollow bamboo wood is cleaved into camber bamboo base, then bamboo base is processed into the bamboo of certain specification Square item is glued to bamboo side's item together, forms bamboo board or bamboo square bar.

(4) dwarf bamboo bamboo wood: being rubbed bamboo beam of consulting by dwarf bamboo recombinant technique, and recombination is glued to together, formed bamboo board or Bamboo square bar.

(5) bamboo wood arc recombinant technique: blueness is gone to be milled into arc bamboo sheet bamboo wood, hot-press gluing forms.

Due to having section in bamboo wood in vain, bamboo wood recombination when can only be processed into the units such as bamboo cane, bamboo beam or bamboo fibre into Row recombination, since unit is small, can only be connected by adhesive, to manufacture the biggish bamboo material of specification.At present in the market Popular bamboo product, is essentially all to recombinate by the way that bamboo wood and adhesive are compound, and consumption glue amount is larger.

In existing bamboo wood recombinant technique and material processing, there are following pollutions:

(1) in adhesive formaldehyde and phenol release

It is toxic in the harmful substances such as adhesive used for bamboo wood release formaldehyde, benzene and process with the rise of green concept Waste liquid and exhaust gas are caused to seriously endanger and confirmed by scientific circles to human health.Relative to timber, bamboo wood recomposition unit is smaller, When processing same size sized products, bamboo wood needs adhesive more, caused by pollute it is bigger.Lauxite (UF), phenol-first The adhesives such as urea formaldehyde (PF), melamine formaldehyde resin (MF), tannin adhesive, polyvinyl acetate emulsion, can discharge trip From phenol and free formaldehyde, cause damages to human body.

(2) noxious materials such as benzene volatilize in coating

Contain a large amount of noxious material, such as formaldehyde, heavy metal, huge malicious pigment, benzene, toluene, free TDI in coating, It discharges, is detrimental to health for a long time during the the producing, selling and uying of material and furniture.

(3) harm of VOCs total volatile organic compounds

The exhaust gas mainly generated during spraying, colored drawing, spray-bonding craft, paint, Tianna solution, glue etc. were using Volatilize the pollutant of generation in journey, and ingredient is mainly VOCs, including benzene, toluene, butyl acetate, ethylbenzene, to () dimethylbenzene, Styrene, ortho-xylene, hendecane etc..

(4) pollution of production process

1) waste water.The waste water that lacquer spraying technique generates in material production.Bleaching agent, chemical steaming liquid, COD, SS etc. have poison Property, if into river water, it is seriously polluted caused by water body, cause water quality physicochemical properties to deteriorate.

2) exhaust gas.Exhaust gas in Material Manufacturing Process mainly has lacquer spraying waste gas and dust.Exhaust gas is mainly in spraying, coloured silk It draws, exhaust gas of generation etc. during spray-bonding craft.

In the production of recombined material, haves the shortcomings that above-mentioned so many and harm using adhesive, but in the prior art There is no the scheme that recombinant material does not use adhesive, reason is:

(1) as the implementation of wildwood protected project, China's timber cutting capacity are sharply reduced, lead to wood supply amount sharply Decline, wood substituted by bamboo be solve timber supply and demand it is contradictory there is an urgent need to.Due to the special structural requirement of bamboo wood itself, by bamboo wood plus Work is recombinated at bamboo unit, could manufacture the recombined material that specification is larger, intensity is high, and bamboo unit is carried out glue with adhesive Conjunction processing is simple, economic, the quick mode of bamboo wood recombination.

(2) bamboo wood industrial processing technology is weaker, belongs to labor-intensive production.Industry is all manufactured more using bamboo wood Multi-product strives for more economic benefits, ignores environmentally protective.

(3) production technology accordingly without glue recombination connection is not developed.

In addition, the bamboo material of existing gluing the shortcomings that there is also easy crackings, in use, existing bamboo matter material Material need environment have certain humidity, if air too dry, material easily occur it is dry and cracked, influence using.Therefore, existing gluing Bamboo material be generally adapted and used in the higher south of humidity, the north is air-dried, and limits bamboo material to a certain degree It uses.

Wooden recombined material in the prior art equally exists the pollution nuisance of adhesive etc., is reassembled into parquet Bulk recombination timber will also use a large amount of adhesives, product and production process to will also result in pollution for environment.With timber It reduces, the usage amount for splicing timber increases, and the pollution problem of the recombination timber of splicing is also urgently to be resolved.

In addition, in actual production, in the production of the nonmetallic equal multiple materials product by metal or other than bamboo and wood Have offcut generation, if it is possible to be recombinated, the kind of recombined material can be increased, be conducive to use, reduce wave Take.

In step 1, the longitudinal length of the bamboo unit and/or the wooden unit is not less than 0.2m；And/or

The diameter of netted bamboo beam or single bamboo silk in bamboo unit is 1~6mm；And/or

Isolated bamboo beam or single bamboo silk, diameter are 0.3~4mm；And/or

The bamboo chip in bamboo unit is to go green or do not go green bamboo chip, size are as follows: with a thickness of 1~15mm, width is 6~80mm, Longitudinal length L >=0.2m；And/or

The size of juggle in the wooden unit are as follows: with a thickness of 1~200mm, width is 10~400mm, longitudinal length L >=0.2m； And/or

It goes green or does not go green arc bamboo sheet, size in bamboo unit are as follows: with a thickness of 1~10mm, width is 6~85mm, Zong Xiangchang Spend L >=0.2m；And/or

By bamboo processing at the size of thin bamboo strips used for weaving are as follows: with a thickness of 0.3~2mm, width is 5~20mm, longitudinal length L >=0.5m；

The step 2 carries out moisture control process to bamboo unit and/or the wooden unit, is by the bamboo unit and/or the wooden unit It is dried at 50~100 DEG C, with moisture control 15~40%；

Further include following steps:

Step 3: by after drying bamboo unit and/or the wooden unit carry out rectangle, arc, circle or odd-shaped cross section as needed The molding assembly group of cell cube is combined into molding assembly, before or after forming assembly, sets on the bamboo unit and/or the wooden unit Set the structure for being adapted to be connected with the connection structure；

Step 4: molding assembly is solidified as a whole by the connection structure as moulding material；

Increase a densification processing step among the step 4, so that the fitting of each unit of molding assembly or moulding material Closely；

Densification processing, be by the good moulding material of assembly at closed high temperature and pressure of the inside with compression mechanism It manages in container, softens bamboo wood with high temperature and high pressure steam, then compress it, and under compression at high temperature and high pressure steam Reason is placed in 0.2 ~ 5h in 160 ~ 195 DEG C of saturated steam, while applying 2.6~9MPa pressure；

Or the densification processing is that the good moulding material of assembly is placed in high frequency press, the hot pressing that high frequency press generates is soft Change densification bamboo matter or wood materials, voltage is 2600 ~ 3400V, and frequency is 6 ~ 10 megahertzs, and the distance of two interpolars is less than 1.4m handles 15 ~ 180min of time, while applying 2.6~9MPa pressure；

After the densification processing, the step 4 is carried out immediately: molding assembly is solidified as a whole by connection structure；It is i.e. logical Cross be bolted, pin connection, rivet interlacement, joggle connection, peripheral metal or nonmetallic attaching means connection structure connection, or seam Connection is closed, more than two connection structures in cold roll riveting or above-mentioned various methods allow the unit after densification to be solidified as a whole, so After be cooled to 70 DEG C hereinafter, pressure release draw materials；Also increase a step after step 4:

Secondary operation: moulding material obtained by the above method progress lateral connection is expanded and/or longitudinally connected spreading again again, As the zero public hazards glueless bamboo matter provided by the invention of bigger specification and/or wooden recombined material；

The secondary operation step is according to the needs of building, decoration, furniture etc., by zero public hazards glueless bamboo matter recombinant material Material is again by connection structure progress laterally and/or longitudinally spreading, to realize zero public hazards glueless bamboo matter and/or wooden as needed Extension is prolonged in the horizontal and vertical expansion of recombined material；

The sofening treatment is 1.5~5h of hot cooking at 75~110 DEG C of temperature；

Connection method in the secondary operation step is: being bolted, pin connection, rivet interlacement, joggle connection, weldering It connects, metal or nonmetallic restraining tube part connection processed, suture connect, more than one in cold roll riveting, for recomposition unit or packet It encloses recomposition unit and carries out horizontal expansion splicing；And/or the cell cube connects extension longitudinally through finger in succession；And/or recombination is single Member or encirclement recomposition unit are bolted, outside joggle connection, pin connection, rivet interlacement, welding, metal or nonmetallic system It encloses attaching means or connector and longitudinal expansion splicing is carried out by one or more of described connection structure；

Step 5: the moulding material of step 4 being solidified as a whole is conserved；It is that the moulding material that will be solidified as a whole is placed in air In or 40 ~ 60 DEG C of dry kilns in dry or microwave drying, by the moisture control 20% of moulding material hereinafter, to moulding material into Row maintenance；

Step 6: the material of maintenance being surface-treated, is that the moulding material that will conserve carries out sanding surface, with tung oil, Asia Sesame oil or edible oil are covered with paint, lacquer, colour wash, etc.；

Between the step 1 and step 2, increase a sofening treatment step, so that the bamboo unit and/or the wooden unit softening； The sofening treatment is that hot cooking, warm water immersion or sodium chloride solution or acetum boiling are impregnated, to bamboo made of step 1 Unit and/or the wooden unit are softened；

The cell cube further includes plastic cement cell cube.
