Abstract
The present invention is a kind of stretch-proof compound braided bag and preparation method thereof, and its parts by weight is：25~28 parts of low density polyethylene (LDPE)；95~110 parts of polypropylene；6~11 parts of toughener；Fill 4~8 parts of reinforcing agent；0.6~1 part of antioxidant；0.8~2.2 part of light stabilizer；0.6~0.9 part of silane coupler, its preparation process is that above-mentioned raw materials are added into high-speed mixer and mixing；Extruder is fed the mixture into, is drawn again through baking oven after water tentatively cools down, the draw ratio for controlling extruder is 1:4, deliver on circular weaving machine and woven after being wound after thermal finalization by up- coiler, woven bag is made after clipped sewing.Stretch-proof compound braided bag technique prepared by the present invention is simple, by adding toughener and filling reinforcing agent, it is dispersed in the gap of polyolefin macromolecule chain hydrocarbon, improve the tensile resistance of compound braided bag, coordinate antioxidant and light stabilizer to use simultaneously, effectively enhance the service life of compound braided bag.
Description
Technical field
The present invention relates to a kind of woven bag technical field, more particularly to a kind of stretch-proof compound braided bag and its preparation side
Method.
Background technology
Compound braided bag is now widely used in the packed and transported of food, cement, fertilizer, grain and other items, therefore, multiple
The tensile resistance for closing woven bag is one of woven bag Performance Evaluating Indexes, and improving the tensile resistance of compound braided bag has turned into
Main competition direction between woven bag manufacturing enterprise.It is poor tensile resistance to be present in most of compound braided bag used at present
Problem, it greatly limit the application field of compound braided bag.
The content of the invention
Present invention seek to address that the deficiencies in the prior art, and a kind of stretch-proof compound braided bag and preparation method thereof is provided.
The present invention to achieve the above object, using following technical scheme：A kind of stretch-proof compound braided bag, its feature exist
In being made up of the raw material of following parts by weight：
Particularly, described toughener is ethylene-octene copolymer.
Particularly, described filling reinforcing agent is any one in ZnOw or glass fibre.
Particularly, described antioxidant is triphenyl phosphite.
Particularly, described light stabilizer is salicyl salicylate (salsalate) to phenol A esters.
The preparation method of a kind of stretch-proof compound braided bag provided by the invention, it is characterised in that comprise the following steps：
(1) it is low density polyethylene (LDPE), polypropylene, toughener, filling reinforcing agent, antioxidant, light stabilizer and silane is even
Connection agent adds high-speed mixer and mixing by the raw material of above-mentioned parts by weight and obtains compound, and mixing temperature is 70 DEG C~90 DEG C, mixing
Time 20min~30min；
(2) compound in step (1) is sent into extruder, heating-up temperature is 120 DEG C~130 DEG C, is tentatively cooled down through water
Drawn again through baking oven afterwards, the draw ratio for controlling extruder is 1:4, deliver to circular weaving machine after being wound after thermal finalization by up- coiler
On woven, woven bag is made after clipped sewing.
The beneficial effects of the invention are as follows：Stretch-proof compound braided bag technique prepared by invention is simple, by adding
Add toughener and filling reinforcing agent, be dispersed in the gap of polyolefin macromolecule chain hydrocarbon, improve the stretch-resistance of compound braided bag
Can, while coordinate antioxidant and light stabilizer to use, effectively enhance the service life of compound braided bag.
