Abstract
The invention discloses a production method for a high-density environment-friendly wood material, which comprises the following steps: 1. taking branches of poplar or various raw materials for later use; 2. machining raw materials into powder of 20-100 meshes; 3. mixing the powder obtained by machining more than two raw materials; and 4. feeding the obtained powder in a formed steel die, heating, pressurizing, plasticizing into blanks with pressure of 50-100MPa at a temperature of 150-180 DEG C, and conducting heat insulation for 10-60 minutes. Pollution can not be caused during the processes from preparation, use and recycling; and the compactness of the materials is up to 1.3-1.4g/cm<3>. The high-density environment-friendly wood material can compare favorably with metals and organic chemical materials, and can be widely used as raw materials of foods and medication and texture machinery, equipments, cars, bearings, structural members and high-grade ornaments. The method is low in cost, simple in process, clean in environment and obvious for industrialization advantages.
Description
Technical field
The present invention relates to a kind of imitation wood's production method, especially a kind of production method of high density environmental protection wood materials, the product that uses this method to produce can be used as the raw material of industrial bearing, structural member and top-grade furniture, decoration, handicraft.
Background technology
The rise of imitation wood's industry is the wooden resources effective utilization of low-quality, alleviates the timber imbalance between supply and demand, promotes the Wood Science and Technology discipline development to bring into play very big effect, but, from being fabricated onto use, because the release of free formaldehyde, most artificial boards all exist problem of environmental pollution to some extent.In addition, the by volume valency is the industry professional etiquette, is management mode with small profits and quick turnover, makes the hot pressing pressure＜10MPa of most artificial boards, because must keep the density＜1.0g/cm of goods
3This just makes artificial board not possess high industrial quality for a long time, have no chance in high added value for a long time.So can create conditions remedies this deficiency of traditional artificial panel technology, the high-quality industrial goods industry of high added value that allows artificial board get into the gram valuation has become artificial board industry problem demanding prompt solution.
Summary of the invention
The technical problem to be solved in the present invention is: at the defective of existing imitation wood's production method existence, a kind of production method of high density environmental protection wood materials is provided, and the product that uses this method to produce can be widely used as the raw material of industrial sliding bearing, structural member and top-grade furniture, decoration and handicrafts such as food machinery, medicine machinery, textile machine, machining equipment and automobile.
Technical solution of the present invention is that the production method of described high density environmental protection wood materials is to adopt following raw material and processing step to make finished product:
One, gets the raw materials ready.One or two or more kinds the plurality of raw materials of getting in the branch of the branch of the branch of white poplar or tailing, tail cabinet eucalyptus or tailing, mao bamboon or tailing, reed stalk, cotton stalk, the oil tea shell is standby;
Two, pulverize.Step 1 is equipped with one or two or more kinds plurality of raw materials in the raw material cuts or be cleaved into block back input pulverizer through sawing or cutting or hand hay cutter and be processed into powder, 20～100 orders sieve;
Three, stir.The powder of two or more raw material processing gained in the step 2 is dropped into batch mixer to uniformly mix;
Four, be shaped.Step 2 gained single variety powder or step 3 gained mixed-powder are dropped in the forming die of formulating according to the specifications design of order requirements, implement heating, pressurization, make raw material in the mould under the double action of heating power and pressure, plastify into a kind of high density environmental protection wood materials briquet finished product, the forming pressure scope is 50～100MPa, the forming temperature scope is 150～180 ℃, temperature retention time 10～60min.
The invention has the beneficial effects as follows,,,, use, arrive the discarded or recovery of goods again, environment is not all polluted to goods from preparation process through facts have proved by the high density environmental protection wood materials of above-mentioned technology preparation; And density of material is up to 1.3～1.4g/cm
3Performance can match in excellence or beauty with metal material, organic chemical industry's material such as powder metallurgy antifriction material and folder cloth phenoplasts, therefore can be widely used as the raw material of sliding bearing, structural member and the high-grade gadget of food machinery, medicine machinery, textile machine, machining equipment, automobile, top-grade furniture.Because the raw material sources of preparation wooden powder sill are extensive and cheap, technology is simple and direct, clean environment, and industrialization is with the obvious advantage, therefore can be described as a kind of typical resource-conserving, clean environment type production technology.
The specific embodiment:
Embodiment 1:
One, it is standby to get the branch of white poplar;
Two, step 1 is equipped with the raw material jagsaw and is slit into block back and drops into pulverizer and be processed into powder, 20 orders sieve;
Three, step 2 gained powder is dropped in the forming die of formulating according to the specifications design of order requirements, implement heating, pressurization, make raw material in the mould under the double action of heating power and pressure, plastify into a kind of high density environmental protection wood materials briquet finished product, forming pressure is 50MPa, forming temperature is 150 ℃, temperature retention time 10min.
Embodiment 2:
One, get cotton stalk, the oil tea shell is standby;
Two, step 1 is equipped with two kinds of raw materials input pulverizer after being cleaved into bulk and is processed into powder, 100 orders sieve;
Three, step 2 gained powder being dropped into batch mixer uniformly mixes;
Four, step 3 gained mixed-powder is dropped in the forming die of formulating according to the specifications design of order requirements, implement heating, pressurization, make raw material in the mould under the double action of heating power and pressure, plastify into a kind of high density environmental protection wood materials briquet finished product, forming pressure is 100MPa, forming temperature is 180 ℃, temperature retention time 60min.
