Description
Technical field
The present invention relates to trade waste in environmental protection technical field process, resource technology field.Specifically, relate to
And resin and glass fibre sorting unit in a kind of waste and old circuit board non-metal powder, realize the non-metal powder of waste and old circuit board is entered
Row recycling.
Background technology
Printed circuit board (PCB), as indispensable important component part in each electronic product, is widely used in household electric
In the electronic products such as device, electronic amusement apparatus, computer.As the high industry of the big production capacity of scale in electronic component industry, closely several
Year, China's printed circuit board industry annual average rate of increase was up to 14.4% unexpectedly, and its yield occupies first place in the world.According to statistics, China is every
More than 500,000 tons of waste and old printed circuit board (wpcbs) is had to need to recycle in year.Now, seek a kind of method of quick environmental protection
To process the wpcbs of enormous amount, to be common issue and research side that the electronic information industry big country such as China, U.S. is faced
To.At present, the recycling of the recycling of waste printed circuit board (wpcbs) mainly wherein metal part.And for accounting for
Total quality more than 60%, but economic benefit is relatively low, processes the also more difficult resource of nonmetallic materials part and safe place
Put relatively fewer.
At present, how using the metal in broken method separation printed circuit board (PCB) and nonmetallic materials, mainly reclaim it
In metal, and the baseplate material granule of waste and old printed circuit board is lost as rubbish.Substrate due to printed circuit board (PCB) (pcb)
Material, is difficult to melt as a kind of same with thermosetting compound material (smc) and dissolves, on the other hand, comprise in same with thermosetting compound material
The inorganic constituentss such as substantial amounts of glass fibre, calorific value relatively low it is impossible to using burn method process.Landfill is to locate on a large scale at present
The main method of reason waste and old printed circuit board substrate, but substrate is lost as rubbish, the substantial amounts of wasting of resources and ring can be caused
Border is polluted.Document " pyrolysis of printed circuit board waste and its product analysis)) (Sun Lushi, Lu Jidong etc., " chemistry of fuel
Report " the 3rd phase in 2002) and document " the Pyrolysis Experiment research of substrate for printed circuit board " (Peng Ke etc., " environmental pollution treatment technology
With equipment " the 5th phase in 2004) describe and process waste and old printed circuit board with method for pyrolysis.The method mainly makes printed circuit
Macromolecular material in plate is cracked into small molecule alkane, can make fuel and industrial chemicals use after rationally reclaiming；Print electricity simultaneously
In the plate of road, the inorganic matters such as glass fibre do not change mostly, or are existed with solid waste form.Due in printed circuit
Contain a small amount of macromolecule organic material in plate, and produce a lot of harmful gass in pyrolytic process (as PBDEs can
Generate many bromos dibenzo dioxanes and PBDF).Therefore, there is high cost, complex process in the method, causes
The problems such as secondary environmental pollution, be not the optimal method of the baseplate material processing waste and old printed circuit board.
Chinese invention patent " manufacture method of the base plate material granules regeneration plate of waste and old printed circuit board " (Xu Zhenming
Deng patent No. 200510023786.x), Chinese invention patent " prepares the side of modified pitch using waste circuit board non-metal powder
Method " (permitted shake bright etc., 200810042789.1) and Chinese invention patent " prepare wood plastic composite using discarded printed circuit boards
Method " (permitted shake bright etc., 200910054313.4) choose obtaining by multiple stage crushing and high-pressure electrostatic partition method of certain particle diameter
To non-metallic particle, mix with multiple additives, molding is obtained regenerated plates, phenolaldehyde moulding compound and wood plastic composite etc.
Multiple regrown materiaves.Glass fibre in non-metal powder can improve the mechanical property of material, but can hinder when content is excessive
The mobility of each raw material such as polyethylene, thus reducing interface binding force, leads to mechanical properties decrease.This is just to control glass fibre
Content in the mixture proposes requirement.Glass fibre in mixture and resin sorting can be opened, it can be greatly improved
Prepare the performance of regenerated plates.Meanwhile, as efficiently separated and can be greatly improved glass fibre in non-metal powder and toner
