Abstract
The artificial wooden material featuring low cost, high strength and flame and moisture resistance is made up of plant fibre, adhesive and solidifying agent through drying plant fibre, breaking, mixing with other components, putting in preheated mould, pressing for one-step forming, and demoulding.
Description
The present invention relates to a kind of new material and production method thereof, especially a kind of artificial wooden material and production method thereof are to replace present expensive natural timber.
Timber is widely used in building decoration, human lives and other industry, because the raising of people's living standard is also increasing to the timber demand amount, thereby causes the timber resources exhaustion.When using timber, the wood size specification also there is certain requirement, in order to address this problem, the density board of Chu Shouing is generally had an optimistic view of in the market, because density board is the timber that size specification is different, is processed into the wood-fibred of certain-length, is furnished with resin glue etc. again, be processed into sheet material through hot pressing, when having solved use timber the timber size specification had desired problem, promptly various grotesque art materials all can obtain utilizing.But this density board is deposited following shortcoming: the raw material of first density board are single, can only be the timber of pure different shape specification; It two is when using density board, occurs the corner waste wood inevitably, and timber is caused a certain amount of waste.
The available mould that the purpose of this invention is to provide a kind of raw material wide material sources is directly produced the artificial wooden material and the production method thereof of product, to solve the problem that produces waste material in the in short supply and use of timber.
Technical solution of the present invention is: component that a kind of artificial wooden material is included and content are:
The component title contains percentage by weight
String 70～90
Adhesive 8～25
Curing agent 0.5～5
In order to make artificial wooden material have flameproof effect preferably, can also add 1～2% fireproof agent within it.
Its production method is: earlier that the string classification is dry, and utilize pulverizer that string is ground into powdery.Get 70～90% plant fiber powders, 8～25% adhesive, 0.5～5% curing agent stirs on mixer, drop into again in the good mould of preheating, preheat temperature is 80 ℃～150 ℃, uses forcing press compression moulding then, and it is 50～80 kilograms per centimeter that the work of forcing press is pressed
2, the dwell time is 3～8 minutes; Product is taken out in last die sinking, can obtain the artificial wooden product of required form.
The present invention compared with prior art, because the Main Ingredients and Appearance of artificial wooden material is a string, the involvement aspect of string is extremely wide, comprise the wood chip that each wood-working factory produces, wood shavings, stub bar, be included in the various plant leafs that produce among industrial and agricultural production and the human lives, skin nuclear, weeds, straw etc., therefore the present invention has the advantage of raw material wide material sources, and used raw material are defective work, thereby cause cost of the present invention low, promptly make full use of defective work, solved the problem of defective work environmental pollution simultaneously again.Because the present invention utilizes mould directly to produce product, does not produce any waste material in the process of product, raw-material utilization rate reaches 100%.Because artificial wooden material contains a certain amount of curing agent and fireproof agent,, have fire protecting performance again again, soak in the water and any distortion did not take place in 26 hours, contact 15 minutes with fire and do not produce combustion phenomena, reach three grades of fire-protection standards so this material promptly has water resistance.
Below the present invention is described in further detail:
At first that the string classification is dry, the scope related owing to string is extremely wide, comprise various wood chips, wood shavings, wooden stub bar, plant leaf, skin nuclear, weeds, straw, peanut and sunflower seeds cot etc., all kinds of strings are carried out drying respectively, its main cause is because the contained moisture content difference of all kinds of strings, required difference drying time, institute's dry back string moisture content is 8～12% to get final product, on common pulverizer string is pulverized then, the fineness of gained plant fiber powder is 80 orders.Get 80 kilograms of plant fiber powders, 15 kilograms of adhesives, adhesive can be selected urine aldehydes resin glue or phenolic resin glue for use, and 4 kilograms of curing agent select for use ammonium chloride as curing agent, and 1 kilogram of fireproof agent selects for use silicate as fireproof agent.Above-described every material is mixed, preferably utilize mixer to stir, again compound is dropped in the mould compression moulding on forcing press.Described mould is the metal die special according to the shape specification of required product, before dropping into compound, at first mould is carried out preheating, make the preheat temperature of mould reach 100 ℃, its operating pressure of described hot press is 60 kilograms per centimeter, and the dwell time is 6 minutes.Last die sinking is taken out product and is got final product.As needs sheet material, can utilize the board mould compacting, just can obtain the sheet material of artificial wooden material.
The present invention is not only limited to the above embodiment, and any possible embodiment all belongs to basic thought of the present invention.
