Description
Technical field
The invention relates to a kind of recycling processing method, particularly a kind of recycling processing method of useless fiberglass resin powder.
Background technology
Printed circuit board (PCB) (PCB) is used in every electric equipment products in large quantities, and the main material of this printed circuit board (PCB) is glass epoxy resin board, and the bonding process that general glass epoxy resin board utilizes epoxy resin to carry out between Copper Foil and glasscloth, to form the sandwich plate that appearance is naked copper, therefore substrate mainly consist of Copper Foil, glasscloth and epoxy resin, and substrate is through internal layer process (pad pasting, exposure, etching, black brown), pressing, boring, a plating (copper plating, secondary copper is electroplated), outer process (pad pasting, exposure, development, etching, striping), spray tin, the handling procedure such as gold-plated and shaping, by the Copper Foil aspect of other Metal plating in substrate, with formed palpus circuit and produce as finished printed circuit board product.
But be alarmingly, except press plate is in manufacture or use procedure, because hole, cut and formed outside waste material, and work as electric equipment products once scrap when becoming waste products, if do not reclaimed by this waste material, or recycling was not at that time, the heavy metal such as tin, copper contained on the discarded printed circuit boards of its inside, and in printed circuit board (PCB), belong to halid epoxy resin, easily cause the second time public hazards of environment especially.
Therefore, how discarded printed circuit board (PCB) is effectively carried out recovery and renewable resource, and this epoxy resin, glass fibre resin and containing metal in the inner, how to be separated, and the metal dissolving how reduced in glass fibre resin, to cause many targets of making great efforts.
Summary of the invention
Therefore, object of the present invention is at the recycling processing method providing a kind of useless fiberglass resin powder, and it by this useless fiberglass resin powder shape one mineral spike, effectively can reduce metal ingredient material stripping in this useless fiberglass resin powder.
So, the recycling processing method of a kind of useless fiberglass resin powder of the present invention, it includes: a material preparation step, its useless fiberglass resin powder of having got everything ready, and an additive, wherein, this additive-package contains at least silicon, aluminium, calcium component, above component content is after being converted to weight percent oxide equivalent, and silicon oxide, aluminum oxide and calcium oxide add up to weight percent between 50% ~ 95%, and this silicon oxide (SiO
2) be 15% ~ 45% weight percent in this additive component, this calcium oxide (CaO) is 20% ~ 60% weight percent in this additive component, this aluminum oxide (Al
2o
3) be 7.5% ~ 30% weight percent in this additive component.
One puddle step, its by this additive and this useless fiberglass resin powder respectively with 5 ~ 50 weight percents: 50 ~ 95 weight percents carry out puddling process, form a mineral spike.
Further, this useless fiberglass resin powder is the thing of a printed circuit board (PCB) through an efflorescence handling procedure gained.
Further, this efflorescence handling procedure has a destruction step, magnetic separation step, abrasive dust step and sorting step; Wherein, this destruction step its this printed circuit board (PCB) is carried out fragmentation, and then obtain a pellet; Separately, this pellet is gone out nonmetal pellet and metal pellet according to gravity separation by this first sorting step; Again, this abrasive dust step carries out abrasive action for nonmetal pellet, has made this nonmetal pellet grind to form an initial spike; Finally, this sorting step is sieve according to the proportion of this break flour to separate metal break flour, to supply subsequent disposal and utilization respectively from this useless fiberglass resin dressing sieve.
After adopting aforesaid method, the present invention is mainly through a material preparation step and a puddle step, namely after purchasing this useless fiberglass resin powder and this additive in this material preparation step, follow-up this useless fiberglass resin powder and this additive are carried out puddling process, with make this useless fiberglass resin powder and additive mixing cured and convert a mineral spike to, and then effectively reduce metal ingredient (especially for copper) material stripping in this useless fiberglass resin powder, impel the Application Areas of this useless fiberglass resin powder wider, use more unrestricted.
