Description
Technical field
The present invention relates to Polywoven Bag, and in particular to a kind of stretch-proof Polywoven Bag and preparation method thereof.
Background technology
Polywoven Bag is with polypropylene (PP), polyethylene (PE) resin as primary raw material, adds a small amount of auxiliary material, after mixing
The melting of extruded machine, extruded plastic foil cut into silk, are stretched under less than resin melt temperature, by molecular orientation with
The flat filament of high intensity, low elongation is made in thermal finalization, then rolled, weave cotton cloth, Polywoven Bag is made in cutting, suture.Plastics are compiled
Knit bag and be divided into TA type, A type, Type B and c-type by loading mass scope, TA type is for allowing 10~20kg of loading mass, A type for allowing
21~30kg of loading mass, Type B are for allowing 31~50kg of loading mass, c-type for allowing 51~60kg of loading mass.Plastic knitting
Bag has that smooth, tension intensity is high, packing is convenient, corrosion-resistant, does not absorb water, does not go mouldy, is easy to handling, pile, carrying and storage
The advantages of, it is adaptable to the packaging of the granular such as industrial chemicals, chemical fertilizer, cement, food, building material and flexible product, is current
Most widely used packaging product on market.
In woven bag production process, the relative pull-off force of flat filament is to control one of key link of woven bag intensity,
It is the most quality index of the Polywoven Bag market quality sampling procedure defective item frequency, manufacturer is in order to reduce into
This, adds reclaimed materials, cheap filling master batch etc. wantonly, causes Polywoven Bag tensile load (with respect to pull-off force) to reduce, with
Industry competition continuous fierce and white-hot, the tensile load for improving Polywoven Bag has become the main side of competition among enterprises
Formula.How to control the relative pull-off force of flat filament, be mainly reflected in the stretching three of the proportioning of raw material, the cooling forming of diaphragm and flat filament
Individual aspect.
The research direction for improving polypropylene plastics woven bag tensile load at present is concentrated mainly on optimizing raw material formula, and
Improvement filling master batch species and performance are the modes main of optimizing raw material proportioning, and the effect of filling master batch is to improve flat filament
Physical property and reduces cost, with the increase of filling master batch loading, the tensile strength of flat filament will be gradually lowered, be because
The Main Ingredients and Appearance of filling master batch is calcium carbonate, without pulling force, after a small amount of filling master batch is added, is dispersed in polyolefin macromolecular chain
Gap in, on the impact of flat filament tensile strength less, now flat filament intensity is improved.
Than later, about in the middle period sixties 20th century, asbestos fibre is filling-modified for the development of Filling and modifying of polypropylene technology
Polypropylene starts in European market appearance.Phase late 1960s calcium carbonate, mica, wood chip especially glass fibre and talcum
The packing materials such as powder start to commonly use.China also begin to study in 20 century 70s polyacrylic filling-modified, and rear
To have carried out substantial amounts of research to polyacrylic filling technique.Packing material species is various, is divided into spherical, cube by shape
Shape, rectangle, slice-shaped and fiber shape;According to chemical composition be divided into inorganic filler and organic filler, inorganic filler include glass, carbon,
Calcium carbonate, metal oxide, metal dust, silica, silicate, other inorganic matters, organic filler include cellulose and modeling
Material etc..
With the development of new technology, polypropylene packing material nanometer also from initial mica and talcum powder expansion till now
(cenosphere, calcium carbonate are brilliant for technical field (nano-calcium carbonate, nano imvite etc.), composite and new material technology field
Palpus, silica-alumina carbon black, magnetic iron oxide etc.) and process for modifying surface field (surfactant, coupling agent, grafting, plasma discharge
Deng), but improve in any case, the performance in a certain respect of polypropylene base-material can only be improved, how by adjusting filling master batch kind
Class and formula, while it is still a difficult problem to improve the stretch-proof of polypropylene plastics woven bag base-material and shock resistance.
CNT has high intensity, toughness and elastic modelling quantity in terms of mechanics.Its elasticity is up to 1TPa, about steel
5 times, almost identical with the elastic modelling quantity of diamond, its elastic strain is about 5%, reaches as high as 12%.CNT no matter
It is intensity or toughness is far superior to all any fibrous material.Using CNT as composite material reinforcement body, can show good
Intensity well, elasticity, fatigue resistance.CNT not only has excellent mechanical property, also has excellent electricity, optical
Energy.Many experiments show, compared with other reinforcements (such as carbon black, carbon fiber or metal charge etc.), CNT is to polymerization
The improvement of thing based composites electric conductivity is more notable, and as CNT has nano-grade size, addition is few, its
Polymer composites can also strengthen its mechanical performance and other performance while good electric conductivity is obtained, while also
Be conducive to the design of macromolecular material other performance, therefore suffer from extensive concern.The active group of carbon nano tube surface is considerably less,
Very weak with the interaction of macromolecular material group, and the draw ratio of CNT and specific surface area are greatly, for preparing height
It is difficult to be uniformly dispersed during molecular composite material in the polymer, agglomeration easily occurs, it is impossible to embodies its excellent properties.Cause
This surface modification to CNT seems particularly important.
To sum up, existing filling master batch feature is single, can not be suitable for mostly polypropylene plastics woven bag shock resistance simultaneously
And the performance requirement of stretch-proof;And the inserts for being used mostly is the inorganic salt filler such as silicate and calcium carbonate and is difficult biological drop
Solve, easily alkalization of soils made, severe environmental pollution can be caused.
Therefore, with polypropylene as base-material, masterbatch raw material type and formula are optimized, science compounds modified CNT,
Inorganic carbonate and silicate are replaced with organic degradable filler, production technology is improved, prepares a kind of stretch-proof environment-friendly type plastic
Woven bag is necessary.
