CN103660004A - Manufacturing method of fine density wood board - Google Patents

Abstract

The invention belongs to the technical field of manufacturing tools for wood boards, and particularly relates to a manufacturing method of a fine density wood board. The manufacturing method of the fine density wood board comprises the following steps that A, waste wood, sawing wood ash, wood residues, bamboos and the like are used and washed through blot removing liquid three to five times; B, the raw materials are conveyed into a first pulverizer through an assembly line, water is added, the powder is ground into wood particles, then the particles are conveyed to a second pulverizer to be ground into wood powder, and the wood power is conveyed into a third pulverizer to be ground into wood pulp; C, epoxy resin is added into the wood pulp, the wood pulp is stirred to be even, and a semi-finished board is formed; D, the semi-finished board obtained in the step C is placed into an extruding machine to be extruded; E, the board is dried through a dryer. The manufacturing method of the fine density wood board has the advantages of being good in water resistance, moisture resistance, winter protection, insect prevention, aging resistance, radiation protection, infrared ray protection, static protection and the like.

Description

A kind of preparation method of precision plank

Technical field

The invention belongs to plank and make apparatus technical field, relate in particular to a kind of preparation method of precision plank.

Background technology

Density board also claims fiberboard, is that to take wood fibre or other plant fiber be raw material, applies the artificial board that Lauxite or other applicable adhesive are made.Difference by its density, is divided into high-density plate, medium-density plate, low-density plank.Density board is because matter is soft shock-resistant, and also easily reprocessing, is a kind of good material of making family property abroad.The density board of at present domestic production mainly exists non-watertight, and water breakthrough is just swollen, and density board water-swellable rate is large, is out of shape large, non-moistureproof, not insect protected, the defect such as easily rot and aging.Density board in use hardness is inadequate, shaky and also its while being used on family property brightness inadequate, so when in use, generally all to make on the surface of density board to paint to protect.And paint harm for human body is larger, so the use of this type of density board exists larger defect.

Summary of the invention

The object of the invention is to solve above-described technical problem, a kind of preparation method of precision plank is provided, its technical scheme is as follows:

A preparation method for precision plank, is characterized in that, its step is as follows:

A: with discarded timber, saw wood ash, wooden short, bristly hair or beard, bamboo etc., spend spot liquid and clean three to five times;

B: the use streamlines such as cleaned timber, saw wood ash, wooden short, bristly hair or beard, bamboo are delivered in first disintegrator, worn into wooden particle with pigment, then become wood powder particle being sent to grinding in the second pulverizer, again send into grinding in the 3rd pulverizer and become wood pulp;

C: epoxy resin is joined in wood pulp, use full-automatic mixer to stir, form semi-finished product;

D: the semi-finished product in C are put in extruder, be squeezed into length 3-4 rice, width is 1-2 rice, and thickness is the sheet material of 0.003-1 rice;

E: adopt dryer to dry all moisture to sheet material.

The preparation method of precision plank provided by the invention is that raw material are prepared with waste products such as discarded timber, saw wood ash, wooden short, bristly hair or beard, bamboos.The precision plank intensity of preparing through this method is fine, uses solid.The smoothness of plate face can bear powerful paddling and there will not be scar.Plank carries various light degree and smoothness, not be used in and uses paint spraying shades of colour.

The present invention has good waterproof, protection against the tide, cold-proof, insect protected, anti-aging, radiation proof, anti-infrared, static etc.Plank does not have the harmful substances such as formaldehyde, benzene.And when using as family property, when various oil stains, various pollutant stain are stained with above, only need to use wet cloth can remove once wiping, very convenient.And plank is due to process high-pressure extrusion, so wear-resistant especially.

The specific embodiment

Illustrate embodiment below:

Embodiment 1:

A preparation method for precision plank, is characterized in that, its step is as follows:

A: with discarded timber, saw wood ash, wooden short, bristly hair or beard, bamboo etc., spend spot liquid and clean three: be inferior;

B: the use streamlines such as cleaned timber, saw wood ash, wooden short, bristly hair or beard, bamboo are delivered in first disintegrator, worn into wooden particle with pigment, then become wood powder particle being sent to grinding in the second pulverizer, again send into grinding in the 3rd pulverizer and become wood pulp;

C: epoxy resin is joined in wood pulp, use full-automatic mixer to stir, form semi-finished product;

D: the semi-finished product in C are put in extruder, be squeezed into 3 meters of length, width is 2 meters, and thickness is the sheet material of 0.003 meter;

E: adopt dryer to dry all moisture to sheet material.

Embodiment 2:

A preparation method for precision plank, is characterized in that, its step is as follows:

A: with discarded timber, saw wood ash, wooden short, bristly hair or beard, bamboo etc., spend spot liquid and clean five times;

B: the use streamlines such as cleaned timber, saw wood ash, wooden short, bristly hair or beard, bamboo are delivered in first disintegrator, worn into wooden particle with pigment, then become wood powder particle being sent to grinding in the second pulverizer, again send into grinding in the 3rd pulverizer and become wood pulp;

C: epoxy resin is joined in wood pulp, use full-automatic mixer to stir, form semi-finished product;

D: the semi-finished product in C are put in extruder, be squeezed into 4 meters of length, width is 1 meter, and thickness is the sheet material of 1 meter;

E: adopt dryer to dry all moisture to sheet material.

Embodiment 3:

A preparation method for precision plank, is characterized in that, its step is as follows:

A: with discarded timber, saw wood ash, wooden short, bristly hair or beard, bamboo etc., spend spot liquid and clean 4 times;

B: the use streamlines such as cleaned timber, saw wood ash, wooden short, bristly hair or beard, bamboo are delivered in first disintegrator, worn into wooden particle with pigment, then become wood powder particle being sent to grinding in the second pulverizer, again send into grinding in the 3rd pulverizer and become wood pulp;

C: epoxy resin is joined in wood pulp, use full-automatic mixer to stir, form semi-finished product;

D: the semi-finished product in C are put in extruder, be squeezed into 3.5 meters of length, width is 1.5 meters, and thickness is the sheet material of 0.5 meter;

E: adopt dryer to dry all moisture to sheet material.

This product is used on furniture, interior decoration plank, building site building, mechanical door and window etc. in a large number.Plank can directly be processed into this series products, does not need to carry out spray paint, allows harm that people are not painted and due to the economic loss of buying paint and causing.
