Description
Technical field
The invention belongs to the plastics such as stationery watercolor pencil stationery processing and manufacturing industry, and in particular to a kind of polypropylene recovery material purification
And reuse method.
Background technology
The polypropylene (PP) such as production in the market and the watercolor pencil scrapped after stationery watercolor pencil and use post sales is returned
The composition of material includes：Thermoprint and screen printing ink, pigment, other impurities.Ink main component is：Colorant+binder+auxiliary agent
(defoamer+diluent+plasticizer+ultra-violet absorber+drier), ink adhesion is strong, is mixed into PP plastics, in high temperature note
It is moulded into type, easily decomposes and cause the defects such as the bubble current mark of injecting products, and polyacrylic molecular chain structure can be destroyed, causes
Plastic degradation, weakens PP mechanical strength.
It because PP feed backs are printed ink, pigment and other impurities pollution, therefore can not directly recycle, cause huge
Waste, if the production of PP feed backs Direct Regeneration is used, the product of production has the defects such as bubble current mark, impurity, and mechanical performance reaches
Less than requiring.
In the prior art, the proportion generally according to PP is 0.905kg/m3, its proportion characteristic smaller than water enter PP feed backs
Row physical cleaning, that is, put it into after being stirred 10 minutes in clear water and filter, but this method can not wash ink, using physics
PP feed backs progress after cleaning, which is molded obtained product, still more than 35% bubble current mark and impurity percent defective.
Therefore, exploitation PP purification and reuse method, the percent defective reduction for recycling PP feed backs, can be enterprise's band
Come economical and reduce pollution, meet environmental requirement.
The content of the invention
The technical problems to be solved by the invention are to provide purification and the reuse method of a kind of polypropylene recovery material, thus side
Polypropylene recovery material after method purification is again after injection molding, and the percent defective of product is low.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
It is an object of the present invention to provide a kind of method of purification of polypropylene recovery material, comprise the following steps：

Preferably, in step (3), after being cleaned to described polypropylene recovery material, described polypropylene recovery material is carried out
Dry.It is further preferred that using blowing drying in step (3).
Because polypropylene recovery material is colourful, therefore, the polypropylene recovery material after recovery can not be used directly, therefore, this hair
It is bright preferably, after step (3), before step (4), described method of purification also includes the step matched colors to polypropylene recovery material
Suddenly.
It is further preferred that by the polypropylene recovery material after color matching gross mass for based on 100%, the formula of described color matching
For：95~97% polypropylene recovery material, 3~5% concentration black color masterbatch.It is further preferable that the formula of described color matching is：
96% polypropylene recovery material, 4% concentration black color masterbatch.
Preferably, in step (4), granulated using extruder, the head of described extruder is provided with 70~100 mesh
Screen pack is to remove undissolved impurity.It is further preferred that being filtered using 80 mesh screen packs.
Preferably, step (5) is separated using apparatus for separating metals to described polypropylene recovery material.
Preferably, through the packaged polypropylene recovery material examined after must purifying of step (6) dried polypropylene recovery material.
It is a further object to provide a kind of reuse method of polypropylene recovery material, using above-mentioned polypropylene recovery material
Method of purification polypropylene recovery material is purified, then add and accounted for after described purification into the polypropylene recovery material after purification
After the nucleator of polypropylene recovery material quality 0.5% be molded obtaining finished product.
Due to polypropylene, feed back is reprocessed after time processing, its mechanical performance and intensity decreases, if using purification
Polypropylene recovery material Direct Regeneration production product afterwards, product cracking and insufficient strength, therefore, the present invention is by poly- third after purification
Nucleator is added in alkene feed back, warpage is shunk to improve polyacrylic crystallization rate and reduce, bending coefficient, increase poly- third is improved
The intensity of alkene, the intensity requirement for making it meet product.
Preferably, described nucleator is Hyperfrom nucleators, more preferably HPN-68L.
Preferably, described finished product is scissors.
The commercially available acquisition of AEO-9, AEO-20, concentration black color masterbatch, HPN-68L used in the present invention.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
