Abstract
The invention relates to the field of plastic woven bags, in particular to production process of a durable woven bag. The production process includes the steps of firstly, evenly mixing, by weight, 80-120 parts of raw material polypropylene, 50-65 parts of ethyl acetate, 20-30 parts of carbon black, 10-18 parts of polyvinyl chloride and 11-15 parts of linear low-density polyethylene in a drying stirrer, and drying under 130-150 DEG C for 15-25 minutes; secondly, extruding the mixed and dried raw materials to form a thin film; thirdly, using a blade to cut the thin film into base filaments, and rolling and forming; fourthly, weaving, printing cutting and sewing to obtain the woven bag. By the production process, the produced woven bag is less prone to aging, long in service life and high in tensile strength.
Description
Technical field
The present invention relates to Polywoven Bag field, the preparation technology of a kind of durable woven bag.
Background technology
Woven bag, also known as Periostracum Serpentis bag, is the one of plastics, is used for packing, and it is each that its raw material is usually polyethylene, polypropylene etc.
Kind of Xylonite raw material, extruded, be drawn into flat filament, then form through weaving, establishment, bag.
Woven bag is usually used in the packaging material of the article such as fertilizer, chemical products.Main production is to utilize plastic raw materials through squeezing
Go out thin film, cutting, simple tension are flat filament, through obtaining product through knitting device.But existing woven bag product is the oldest
Changing, service life is short, and anti-ultraviolet function is poor, and tensile force is low so that the article of loading easily produce putrid and deteriorated,
Goods is moved in way because the tear breakage of woven bag midway causes cargoes from scattering completely to be difficult to consolidation.Therefore, it is badly in need of improving woven bag
The performance of material, simultaneously improves the knitting skill of woven bag, extends the service life of woven bag and improves tensile property..
Summary of the invention
In order to make up the deficiencies in the prior art, the preparation technology of heretofore described a kind of durable woven bag, it is prepared into
The Polywoven Bag extensibility arrived is high, and service life is long.
The technical solution adopted for the present invention to solve the technical problems is: the preparation technology of a kind of durable woven bag, including
Following steps:
(1) in terms of parts by weight, by raw material polypropylene 80～120 parts, ethyl acetate 50～65 parts, white carbon black 20～30
Part, polrvinyl chloride 10～18 parts and linear low density polyethylene 11～15 parts, put in dry blender and mix
After Jun Yun, at 130～150 DEG C, dry 15～25min；
(2) raw material after combination drying is put into extruder is extruded into thin film；
(3) thin film blade is cut into embryo silk, and be stretched formation flat filament through baking oven, shrink through thermal finalization, traction,
K cryogenic treatment at 25～45 DEG C, last rolling molding, wherein draw ratio is 1:3～1:6；
(4), after rolling molding, woven, Yin Qie and sewing obtain described woven bag.
Preferably, in described step (1), baking temperature is 140 DEG C, and drying time is 25min.
Beneficial effect: the preparation technology of heretofore described a kind of durable woven bag, woven bag is difficult to aging, uses
Life-span is long, and tensile force is high so that the article of loading are not likely to produce putrid and deteriorated, not cracky.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with
Embodiment, is expanded on further the present invention.
The preparation technology of a kind of durable woven bag, comprises the following steps:
(1) in terms of parts by weight, by raw material polypropylene 80～120 parts, ethyl acetate 50～65 parts, white carbon black 20～30
Part, polrvinyl chloride 10～18 parts and linear low density polyethylene 11～15 parts, put in dry blender and mix
After Jun Yun, at 130～150 DEG C, dry 15～25min；
(2) raw material after combination drying is put into extruder is extruded into thin film；
(3) thin film blade is cut into embryo silk, and be stretched formation flat filament through baking oven, shrink through thermal finalization, traction,
K cryogenic treatment at 25～45 DEG C, last rolling molding, wherein draw ratio is 1:3～1:6；
(4), after rolling molding, woven, Yin Qie and sewing obtain described woven bag.
Preferably, in described step (1), baking temperature is 140 DEG C, and drying time is 25min.
The ultimate principle of the present invention, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry,
The present invention is not restricted to the described embodiments, the principle that the present invention is simply described of the description in above-described embodiment and description,
Without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these changes and improvements are all
Fall in scope of the claimed invention.Claimed scope is by appending claims and equivalent circle thereof
Fixed.
