Description

A kind of production technology of high performance plastics woven bag
Technical field
The present invention relates to woven bag technical field of producing more particularly to a kind of production works of high performance plastics woven bag Skill.
Background technology
Nowadays Polywoven Bag has become one of indispensable article in life and production, and Polywoven Bag is compiled in modeling Refer to be woven into the packaging material for being used to contain various articles of cloth in industry with plastic foil drawing fiber silk.Its with polypropylene, Polyvinyl resin is primary raw material, and extruded wire drawing is into flat filament, then the product formed through weaving, bag making.Traditional plastic knitting Bag more emphasizes its delivered payload capability, and heat resistance, weatherability are poor, and service life is shorter.
Invention content
Present invention seek to address that the deficiencies in the prior art, and provide a kind of heat resistance and weatherability is higher, service life compared with The production technology of high performance plastics woven bag long and that plastic woven bag aesthetics can be improved.
The present invention to achieve the above object, using following technical scheme：A kind of production technology of high performance plastics woven bag, Include the following steps,
1) film forming：The polypropylene of formula ratio, filler, stabilizer, lubricant, coupling agent are sent into blender, mixed 10~15min is dried after mixed in 105~115 DEG C of environment, melting machine is then sent by conveyer, melting machine temperature rises to 230~250 DEG C, immediately enter extruder after melting, the plastic film of extrusion is thin into solid-state is cooled in 30~35 DEG C of water Film；
2) flat filament is molded：Solid film is cut into embryo silk with cutter, embryo silk is handled successively by hot-stretch and thermal finalization Form flat filament；
3) fabric is molded：Flat filament is sent into four-shuttle circular loom, four-shuttle circular loom rotating speed is controlled at 100~130 revs/min；
4) bag product are molded：By fabric after cutting, printing, suture after make woven bag.
Preferably：The weight percent of each raw material in step 1) is, polypropylene 75~85%, filler 10~20%, Stabilizer 1~2%, lubricant 1~2%, coupling agent 1~2%.
Preferably：The filler is nano-calcium carbonate, and the stabilizer is epoxy resin, and the lubricant is tristearin Acid, the coupling agent are titanate esters.
The beneficial effects of the invention are as follows：Nano-calcium carbonate is added in the mixed raw material of the present invention can not only reduce cost, also Rigidity, toughness, bending strength of material etc., while the ordinary temperature stability of changeable Polywoven Bag, thermostabilization can be effectively increased Property, mobility and product print distinctness and firmness；Titanate coupling agent can handle filler surface, make filler material and Carrier organically combines, and makes plastics mixing, dispersion evenly；In order to prevent material during processing and use by light and heat Action breaks and destruction, prolong the service life, in the feed add in epoxy resin stabilizer；Stearic acid can not only be used for lubricating Agent improves the smooth and beautiful appearance on Polywoven Bag surface, is alternatively arranged as dispersant, prevents from mutually assembling between filler particles, Improve mobility during processing and forming.
Specific embodiment
With reference to embodiment, the invention will be further described：
Embodiment 1, specific production technology of the invention be,
Include the following steps,
1) film forming：By the raw material of following weight percent, polypropylene 80%, nano-calcium carbonate 15%, epoxy resin 2%th, stearic acid 2%, titanate esters 1% are sent into blender, dry 15min after blending in 110 DEG C of environment, then pass through conveying Machine is sent into melting machine, and melting machine temperature rises to 245 DEG C, melts best results, extruder, the plastics of extrusion are immediately entered after melting Into solid film is cooled in 33 DEG C of water, (cooling can make melt shape to film, can also avoid high-temperature oxydation and prevent material Crystallization)；
2) flat filament is molded：Solid film is cut into embryo silk with cutter, embryo silk is handled successively by hot-stretch and thermal finalization Form flat filament；
3) fabric is molded：Flat filament is sent into four-shuttle circular loom, four-shuttle circular loom rotating speed is controlled at 120 revs/min；
4) bag product are molded：By fabric after cutting, printing, suture after make woven bag.
First, cost can not only be reduced by nano-calcium carbonate being added in mixed raw material of the invention, can also be effectively increased material Rigidity, toughness, bending strength etc., while ordinary temperature stability, thermal stability, mobility and the system of changeable Polywoven Bag Product print distinctness and firmness, this uses the nano-calcium carbonate of 2500 mesh, and the input of the calcium carbonate of fine granularity to compile The mechanical property of fabric more preferably, but with the increase of filler usage amount, in order to ensure that its performance must accordingly improve other originals The input amount of material causes cost excessively high；Titanate coupling agent can handle filler surface, make filler material and carrier (polypropylene) It organically combines, makes plastics mixing, dispersion evenly；Material is made during processing and use by light and heat in order to prevent With decomposing and destroying, prolong the service life, add in epoxy resin stabilizer in the feed；Stearic acid can not only be used for lubricant, carry The smooth and beautiful appearance on high Polywoven Bag surface, is alternatively arranged as dispersant, prevents from mutually assembling between filler particles, and molding adds Working hour good fluidity.
Secondly, step 2) of the invention be committed step, the embryo silk after cutting have to pass through hot-stretch processing just with compared with Big pulling force, but in order to prevent larger contraction is generated during the braiding of embryo silk afterwards, it is necessary to it is carried out at thermal finalization Reason.
Embodiment 2, specific production technology of the invention be,
Include the following steps,
1) film forming：By the raw material of following weight percent, polypropylene 75%, nano-calcium carbonate 20%, epoxy resin 1%th, stearic acid 2%, titanate esters 2% are sent into blender, dry 10min after blending in 105 DEG C of environment, then pass through conveying Machine is sent into melting machine, and melting machine temperature rises to 250 DEG C, and extruder is immediately entered after melting, and the plastic film of extrusion enters 35 DEG C Water in be cooled to solid film；
2) flat filament is molded：Solid film is cut into embryo silk with cutter, embryo silk is handled successively by hot-stretch and thermal finalization Form flat filament；
3) fabric is molded：Flat filament is sent into four-shuttle circular loom, four-shuttle circular loom rotating speed is controlled at 130 revs/min；
4) bag product are molded：By fabric after cutting, printing, suture after make woven bag.
Embodiment 3, specific production technology of the invention be,
Include the following steps,
1) film forming：By the raw material of following weight percent, polypropylene 85%, nano-calcium carbonate 10%, epoxy resin 2%th, stearic acid 1%, titanate esters 2% are sent into blender, dry 13min after blending in 115 DEG C of environment, then pass through conveying Machine is sent into melting machine, and melting machine temperature rises to 230 DEG C, and extruder is immediately entered after melting, and the plastic film of extrusion enters 30 DEG C Water in be cooled to solid film；
2) flat filament is molded：Solid film is cut into embryo silk with cutter, embryo silk is handled successively by hot-stretch and thermal finalization Form flat filament；
