Abstract
The process for preparing high-quality CA plastic particles includes such steps as recovering waste single-component artificial filaments, pretreating, addition of DMP and DEP assistants, extrusion, drawing, cooling and cutting. Its special drawing machine is composed of material cylinder, screw bolt, filter plate and die.
Description
The present invention relates to the recovery of one-component and artificial filament's waste material, also relate to the wire drawing machine that is exclusively used in according to this manufactured CA plastics.
CA plastics (cellulose acetate), Latin is called Acetabel, belongs to the engineering plastics class.As everyone knows, at present cigarette adopts with filter tip that acetate fibres is quilted to be made more, raw material mainly relies on import, cost an arm and a leg, the whole nation annual produce cigarette have in the filter tip process a large amount of leftover bits not markon's land used run off in vain, some lawless persons utilize the waste silk of cigarette material factory to wad a quilt with cotton to make and sell false smoke in a large number and civilian bat is reaped staggering profits.On September 5 nineteen ninety, Chinese patent CN1045138A discloses a kind of " regeneration method of cigarette-used plastic cotton ", this method acetone (chemical formula CH
3OOCH
3) as solvent, cigarette-used plastic cotton Celluloseacetate cigarette filter tow waste product directly is dissolved as solution, method with evaporation is removed typing with acetone (56.5 ℃ of boiling points), the acetone recycling use that evaporates, reform the hole shape of spray silk machine spray orifice into star, make the tow of regeneration form honeycomb shape after rolling extruding, hole is crowded not dead around guaranteeing, good filter effect is arranged.But its goal of the invention is disagreed with national relevant health regulation, reuses because of the relevant health regulation of country does not allow edible packing plastics secondary recovery.
The purpose of this invention is to provide a kind of method with manufacturing CA plastic particles using waste filament, its CA plastic grain of producing can be as the primary raw material of plastics process industries such as optical instrument, electronic components, glasses;
Another object of the present invention provides a kind of wire drawing machine, make the CA plastics can be at a high speed processing step by wire drawing after the secondary filter.
For achieving the above object, the present invention adopts following process:
