Abstract
This invention discloses a method for preparing uniformly powder-doped plastic biofiller. The method comprises: placing plastic granular matrix in a stirring kettle, heating or spraying liquid adhesive so that the surface of plastic granular matrix has viscosity, adding powder, stirring, adhering powder to the surface of plastic granular matrix, adding coupling agent and wetting agent, placing inan injection molding machine, and injection-molding to obtain uniformly powder-doped plastic biofiller. The obtained uniformly powder-doped plastic biofiller has such advantages as high uniformity, good appearance, and high powder doping amount, high processability, no dust, no environmental pollution and no harm to operator's health.
Description
Technical field
The present invention relates to the even modification of powder of injection-molded plastic goods, the powder-modified method that particularly relates to used plastic biologic packing material in trade effluent or the sanitary sewage biomembrance process treatment process belongs to and is processing of high molecular material forming technique and water-treatment technology field.
Background technology
Biologic packing material is one of core technology of biomembrance process water treatment procedure, is that starting material are made with macromolecular materials such as polypropylene, polyethylene, polyvinyl chloride, polystyrene or polyester usually.Because the wetting ability and the biological activity of plastic biologic packing material are relatively poor, in recent years by add all kinds of powders in base material, Chinese invention patent CN1522972, CN1263054 and CN1350984 disclose several powder-modified fillers such as the affine hydrophilic filler of biology, magnetic fillers and nutrition slow-release filler etc.These new fillers are in preparation process, normally powder and plastic grain base material are directly mixed, because plastic grain and particle diameter, density and the surface property of being added between powder have than big-difference, plastic biologic packing material is in injection moulding process, can take place to mix uneven, powder sinks in the injection moulding machine hopper, causes the powder filled amount of each modification biological filler to differ; Sometimes owing to the powder that enters screw in injection molding machine is too much, can make filler be difficult to moulding; In the production process in addition can take place also that light powder flies upward, phenomenon such as pollutant atmosphere and infringement operator are healthy.
Summary of the invention
The objective of the invention is to overcome the shortcoming that the powder-modified method of existing plastic biologic packing material exists, propose a kind of make all kinds of powder additives in a large number and equably adsorbed close in the powder-modified method of the plastic biologic packing material on plastic grain surface, made plastic biologic packing material quality is even, workability is good, and its microorganism colonization performance and water treatment efficiency improve.
The present invention realizes by following technical proposals:
A kind of preparation method of plastic biologic packing material of even adulterated powder: earlier the plastic grain base material is put into stirring tank; add powder to be added after making the plastic grain substrate surface have viscosity; continue to stir; powder mixture is attached on the plastic grain surface equably; add the coupling lubricant, put into the plastic biologic packing material that the injection moulding machine injection moulding gets even adulterated powder.
For further realizing the object of the invention, the preparation method of the plastic biologic packing material of even adulterated powder puts into the plastic grain base material stirring tank of one band heating unit earlier, the still temperature is warming up to more than the plastic grain fusing point, until the plastic grain surfaces of tacky, insulation; Add various powder mixtures to be added, continuation was stirred 1-3 minute, stopped heating then, and powder mixture just is attached on the plastic grain surface equably, put into the injection moulding machine injection moulding behind a small amount of lubricated coupling agent of cooling and interpolation and got required filler;
In parts by weight, the consumption of described plastic grain base material, powder and coupling lubricant is:
80～95 parts of plastic grain base materials
5～20 parts of powders
0.5～1 part of coupling lubricant.
A kind of preparation method of plastic biologic packing material of even adulterated powder puts into a stirring tank with the plastic grain base material earlier, spray into liquid adhesive while stirring rapidly, under whipped state, add various powder mixtures to be added, continue to stir 3-5 minute; This moment, powder mixture will be attached on the plastic grain surface, put into the injection moulding machine injection moulding behind the lubricated coupling agent of interpolation and got required filler;
In parts by weight, the consumption of described plastic grain base material, powder and coupling lubricant is:
80～95 parts of plastic grain base materials
5～20 parts of powders
1～3 part of liquid adhesive
0.5～1 part of coupling lubricant.
Described plastic grain base material is: polypropylene GRANULES or polyethylene particle or granules of polystyrene or polyester granulate etc.;
The powder of described filler modified usefulness is: one or more mixtures of powder masss such as gac, magnetic, starch, flour, bagasse, wood chip, alginate calcium, jelly powder, bone meal, oyster shell whiting, straw powder, maize bar powder, staple fibre, polyvinyl alcohol powder, hydroxyapatite, chitosan and derivative thereof; Described magnetic comprises wherein one or more mixtures of Z 250, ferric oxide, iron monoxide, barium ferrite, the strong magnetic particle of rare earth such as neodymium iron boron.
Described tamanori is: to the water treatment nontoxic all kinds of tamanoris of microorganism such as amylan or dextrin glue or polyvinyl alcohol glue or the special-purpose tamanori of fluidized granulation machine;
Described coupling lubricant comprises one or more mixtures of stearic acid, vegetable and animals oils, white mineral oil.
The principle of the invention: propose a kind of heat and stick dispersion or tamanori thin liquid dispersion technology, promptly earlier the plastic grain thermoplastic is clamminess, or spray into the small amount of adhesive thin liquid, make powder be attached on the plastic grain equably, carry out injection moulding again, thereby guaranteed the even doping of all kinds of powders and the unanimity of modification biological filling property.
The present invention compares with existing powder adding technique, has the following advantages and beneficial effect:
1, the maximum addition of powder improves, can bring up to by original 15wt% after the modification near 20wt%.Especially the additive effect of magnetic improves obviously, because it very easily sinks to the bottom in the injection moulding machine hopper than great, and enters screw in injection molding machine at first in a large number and results in blockage when directly adding magnetic, and the particle content of moulding filler was then on the low side afterwards.
2, adopt the inventive method then can make the various powder additions of each filler keep uniformity, the filler workability is good, this is because powder is attached on the plastic grain surface equably, in the process of injection moulding, just avoid lightweight powder airborne dust, caused surrounding environment to pollute or influence health of operators, also can avoid the heavy powder to sink to stopping up the phenomenon of screw rod, therefore help machine-shaping.
3, the powder-modified biologic packing material quality that makes is even, attractive in appearance.
Embodiment
The invention will be further described below in conjunction with embodiment; the contriver to the present invention through for many years creative research and test; many successful examples are arranged, enumerate the part specific embodiment below, but the scope of protection of present invention is not limited to the scope of embodiment statement.
