Abstract

The invention relates to a production method of green environmental-friendly artificial wood, which comprises the following raw materials and process steps that: 1. a solid wood sheet, solid wood scrap wood and lignin are prepared; 2. the solid wood scrap wood is processed into powder and filtered by a 20 to 40-mesh screen; 3. the powder prepared in step 2 and the lignin are mixed and stirred sequentially by the weight ratio of 70 to 95: 5 to 30; 4. the prepared solid wood sheet is laid in a mold, a layer of the prepared mixed powder is paved according to a 'sheet-mixed powder' or 'sheet-mixed powder sheet' lamination mode or the other layer of solid wood sheet is paved, a stamp is heated to obtain a briquette, the pressure is 1 to 10Mpa, and the temperature is 140 to 170DEG C. The temperature is insulated for 10 to 60min to obtain the finished product. The method does not produce environment pollution. The product is widely used as the material of cars, house decoration and furniture. The raw materials used by the method have wide source, the price is low, the process is simple, and the industrial advantages are significant.

Description

A kind of production method of green environmental-friendly artificial wood

Technical field

The present invention relates to a kind of ornament materials, especially a kind of production method that can be used as the green environmental-friendly artificial wood of automobile and house decoraton or furniture making.

Background technology

Along with human civilization advance, people to clothing, food, live, the quality requirements of row improves constantly.Because timber has affinity to the mankind, people are continuous for the pursuit of the high-grade solid wood interior trim of automobile, solid wood building materials, solid wood furniture.But owing to exploding of population, the superpower felling of forest, tellurian trees are less and less, and rare expensive high-grade timber material difficulty is especially asked.China becomes one of serious deficient country of global timber already, and in the face of facts of life, people have to look for second solution and select artificial boards such as glued board, fiberboard, lumber core.Yet these materials have added a large amount of urea-formaldehyde resin adhesives or phenolic resin glue, and additional proportion or up to 30～40% inevitably can discharge the formaldehyde of contaminated environment in the use! Therefore people wait in expectation always appealing a kind of nontoxic, even can give again simultaneously vision really and truly the appearance of artificial board of the high-grade solid wood sensation of a kind of solid wood.

Summary of the invention

The technical problem to be solved in the present invention is, defective at the prior art existence, a kind of production method of green environmental-friendly artificial wood is provided, the artificial timber product that uses this method to produce is nontoxic, as decorating or make furniture environment is not caused any pollution, just look at up very high-grade as automobile, building construction.

Technical solution of the present invention is that the production method of described green environmental-friendly artificial wood is to adopt following raw material and processing step to make the green environmental-friendly artificial wood product:

One, gets the raw materials ready.Prepare following raw material: solid wood thin plate, solid wood leftover pieces or solid wood saw dust or solid wood wood shavings or mao bamboon or reed stalk or cotton stalk or hemp stalk, lignin or modified lignin resin;

Two, pulverize.A kind of raw material or plurality of raw materials input pulverizer that step 1 is equipped with in solid wood leftover pieces or solid wood saw dust or solid wood wood shavings or mao bamboon or reed stalk or cotton stalk or the hemp stalk are processed into powder, and 20～40 orders sieve;

Three, stir.Step 2 gained powder and lignin that step 1 is equipped with or modified lignin resin successively by 70～95: 5～30 weight ratio compatibility, are uniformly mixed;

Four, be shaped.Step 1 is equipped with the solid wood thin plate to be flat on according in the prefabricated mould of design specification, by " thin plate-mixed powder " or " thin plate-mixed powder-thin plate " stacked pattern, lay one deck above-mentioned steps three gained mixed-powders on the solid wood thin plate in described mould, or continue on the shop mixed-powder, to go again to lay one deck solid wood thin plate, implement heating and mould pressing and get briquet, the forming pressure scope is 1～10MPa, and the forming temperature scope is 140～170 ℃.Insulation 10～60min gets finished product.

The invention has the beneficial effects as follows,,, therefore, can not cause environmental pollution from producing, use to discard because raw material and the technology selected for use all are raw material and the technology that meets environment protection requirement by the imitation wood and the goods thereof of above-mentioned technology preparation.Product can be widely used as the material that automobile, house decoraton and furniture are made.Because the raw material wide material sources of this green environmental-friendly artificial wood of preparation and cheap, technology is simple and direct, so industrialization is with the obvious advantage.

The specific embodiment:

Embodiment 1:

One, gets the raw materials ready.Prepare following raw material: poplar thin plate, poplar leftover pieces, lignin;

Two, pulverize.Step 1 is equipped with poplar leftover pieces input pulverizer is processed into powder, 20～40 orders sieve;

Three, stir.Step 2 gained powder and lignin that step 1 is equipped with are pressed 70: 5 weight ratio compatibility successively, uniformly mix;

Four, be shaped.Step 1 is equipped with the poplar thin plate to be flat on according in the prefabricated mould of design specification, by " thin plate-mixed powder " stacked pattern, lay one deck above-mentioned steps three gained mixed-powders on the poplar thin plate in described mould, implement heating and mould pressing and get briquet, forming pressure 1MPa, 140 ℃ of forming temperatures.Insulation 10min gets finished product.

Embodiment 2:

, get the raw materials ready.Prepare following raw material: pine thin plate, hemp stalk, modified lignin resin;

Two, pulverize.Hemp stalk that step 1 is equipped with is dropped into pulverizer be processed into powder, 20～40 orders sieve;

Three, stir.Step 2 gained powder and modified lignin resin that step 1 is equipped with are pressed 95: 30 weight ratio compatibility successively, uniformly mix;

Four, be shaped.Step 1 is equipped with the pine thin plate to be flat on according in the prefabricated mould of design specification, by " thin plate-mixed powder-thin plate " folded mould pattern, lay one deck above-mentioned steps three gained mixed-powders on the pine thin plate in described mould, on the shop mixed powder, lay one deck pine thin plate again, implement heating and mould pressing and get briquet, forming pressure 10MPa, 170 ℃ of forming temperatures.Insulation 60min gets finished product.
