Description
Technical field
The invention mainly relates to packaging material processing technique field more particularly to a kind of wear-resisting waterproof flour packaging bags.
Background technique
Packaging bag is seen everywhere in daily life, and common packaging bag has plastic material packaging bag, paper material packaging
Bag and nonwoven fabrics package bag, but the woven bag of the mostly plastic material currently used for packaging flour, lower production costs, in order to
It prevents Polywoven Bag from flour leakage and water suction occur, needs to increase plastic foil inside woven bag, if polybag and splendid attire
Flour be in the condition of high temperature for a long time, be easy to cause harmful components to ooze out, very big harm can be generated to human health.
Non-woven fabrics has the characteristics that environmentally protective, soft light, the current packaging for starting gradually to be used for flour, but at present
For the nonwoven fabrics package bag used since preparation process is immature, intensity is low, can be because of abrasion in the storage and transportational process of flour
Flour is leaked, the outside of packaging bag is made to be covered with starch, it is inconvenient to carry after causing consumer to buy, and can make to be stained on hand and clothes
Flour is contaminated, and flour can be penetrated into quickly after packaging bag chance water, can make flour is mouldy to damage by worms, lead to a large amount of economic loss.
Summary of the invention
In order to make up the defect of prior art, the object of the present invention is to provide wear-resisting waterproof flour packaging bags.
A kind of wear-resisting waterproof flour packaging bag, the wear-resisting waterproof layer including intermediate basal layer and two sides.
The wear-resisting waterproof layer of the two sides, is made of the raw material of following parts by weight: natural emulsion 27 ~ 29, nanometer vermiculite
16 ~ 18, nano-titanium dioxide 12 ~ 14, negative ion powder 5 ~ 7.
The basal layer of the centre is made of the raw material of following parts by weight: polyvinyl chloride fibre 27 ~ 29, polypropylene fibre 27 ~ 29, copper ion
Fiber 11 ~ 13, modified ceramic fiber 8 ~ 10.
Ceramic fibre is placed in the acetum that volume fraction is 2 ~ 3% by the modified ceramic fiber, impregnates 20 ~ 30
Minute, be added 5-flurocytosine, additional amount be ceramic fibre weight 0.02 ~ 0.03%, be uniformly mixed, in 40 ~ 45 DEG C, 32 ~
34kHz ultrasound 15 ~ 25 minutes, make ceramic fibre to 5-flurocytosine carry out absorption and branch knot, increase ceramic fibre intensity and
Bacteriostasis property takes out, dry, obtains modified ceramic fiber.
A kind of preparation method of wear-resisting waterproof flour packaging bag, comprising the following steps:
(1) prepared by basal layer: polyvinyl chloride fibre, polypropylene fibre, copper ion fiber and modified ceramic fiber being weighed by weight, are dipped in three
It in polyphosphate sodium solution, is uniformly mixed, is laid with networking, intensity and load-bearing capacity with higher, anti-mildew sterilization can be avoided packet
There is breakage in transport and handling process repeatedly in pack, reduces flour loss, obtains substrate web；
(2) reinforce molding: substrate web progress high frequency is hot-forming, and frequency is 110 ~ 120kHz, is arranged, and weight is
70~75g/m2, obtain basal layer；
(3) two sides blooming: natural emulsion, nanometer vermiculite, nano-titanium dioxide and negative ion powder are uniformly mixed, it is heated to 70 ~
80 DEG C, even application can avoid packaging bag two with intermediate basal layer close adhesion, soft abrasion-resistant in basal layer, Nantural non-toxic
The wear-resisting waterproof layer of side occurs damaged, so that packaging bag is repeated as many times and uses, reduces the packing cost of flour, with a thickness of 13 ~
15 μm, ultraviolet lighting can promote wear-resisting waterproof layer to be firmly combined with basal layer, improve the durability of packaging bag, obtain wear-resisting anti-
Water non-woven fabrics；
(4) bag making: being cut out wear-resisting water proof nonwoven cloth and sew according to size, and molding obtains wear-resisting waterproof flour packaging bag.
The sodium tripolyphosphate solution of the step (1), concentration are 25 ~ 30mg/L.
The ultraviolet lighting of the step (4), power 300W Continuous irradiation 20 ~ 30 minutes, stop 8 ~ 10 minutes, repeat
Irradiation 2 ~ 3 times.
The invention has the advantages that wear-resisting waterproof flour packaging bag provided by the invention, environment protection health, intensity is high, wearability
By force, outside moisture can be effectively prevent to penetrate into flour, avoid flour is mouldy in storage and transportational process from damaging by worms, while can keep away
Exempt from flour and is exuded to surface out of packaging bag, it can be easy to carry after buying consumer；Packaging bag is divided into three layers, including centre
Basal layer and two sides wear-resisting waterproof layer, basal layer is prepared by polyvinyl chloride fibre, polypropylene fibre, copper ion fiber and modified ceramic fiber
Non-woven fabrics, intensity and load-bearing capacity with higher, anti-mildew sterilization can be avoided packaging bag in transport and handling process repeatedly
Middle appearance is damaged, reduces flour loss, and the wear-resisting waterproof layer of two sides by natural emulsion, nanometer vermiculite, nano-titanium dioxide and is born
Ion powder is mixed, Nantural non-toxic, can avoid the resistance to of packaging bag two sides with intermediate basal layer close adhesion, soft abrasion-resistant
It grinds waterproof layer and breakage occurs, so that packaging bag is repeated as many times and use, reduce the packing cost of flour；Basal layer prepare when be by
Multiple fiber be added sodium tripolyphosphate solution in, the binding strength of fiber can be increased, improve nonwoven fabrics package bag intensity and
Biocidal property inhibits bacteria breed, avoids packaging bag is mouldy from rotting, extends the service life of packaging bag；Modified ceramic fiber is first
Ceramic fibre is added to the acetum of low concentration, increases the porosity and adsorptivity of ceramic fibre, adds 5-flurocytosine,
So that ceramic fibre is carried out absorption and branch knot to 5-flurocytosine, increases the intensity and bacteriostasis property of ceramic fibre；Two sides it is wear-resisting
It is sprayed at basal layer two sides after waterproof is heated, and carries out intermittent ultraviolet light irradiation, wear-resisting waterproof layer and substrate can be promoted
Layer is firmly combined, and improves the durability of packaging bag.
