Abstract
The invention discloses an easily degraded shopping bag or an easily degraded product package and a method for preparing the same. The shopping bag is prepared by polyvinyl alcohol mucilage, gypsum, plant fiber stuff, salt, antifoam additive, nontoxic water repellent and oil resistance agent according to a certain weight portion proportion. The manufacturing method is as follows: fodder is added with water and grinded into slurry; polyvinyl alcohol is added with water and heated and made into the mucilage; the polyvinyl alcohol mucilage, gypsum, the plant fiber stuff, the salt, the antifoam additive, the nontoxic water repellent and the oil resistance agent are mixed according to a certain proportion, infused into a die and quickly dried; and the easily degraded shopping bag or the easily degraded product package is formed after cutting and edge plastering. The easily degraded shopping bag or the easily degraded product package and the method have the advantages that: the package can be degraded and is environment-friendly; the manufacturing raw materials are easy to obtain and low in cost; the preparation technique is simple and the manufacture is easy; and the easily degraded shopping bag or the easily degraded product package can be reused.
Description
Technical field:
The present invention relates to chemical industry, specifically is a kind of shopping bag of easy degraded or packing of product bag and preparation method thereof.
Background technology:
The shopping bag that uses on market at present though made things convenient for masses' use, because of being polyethylene plastic bag mostly, is difficult for degraded, has caused the serious environmental pollution, and existing country explicit order requires to stop using.
Summary of the invention:
The objective of the invention is for overcoming the deficiencies in the prior art, and provide a kind of cheap, raw materials for production are easy to get, easy to manufacture, with after can degrade fast, and shopping bag recyclable reprocessing, environment amenable easy degraded or packing of product bag and preparation method thereof.
The present invention realizes by following technical proposals:
The formula material of shopping bag of the present invention and consumption weight part ratio are:
Polyvinyl alcohol mucus 5
Gypsum 1
Vegetable-fibre slurry 1
Salt 0.01
Defoamer 0.01
Nontoxic water-resisting agent 0.1
Oil resistance agent 0.1.
Described polyvinyl alcohol mucus is polyvinyl alcohol: water=1: 3-4 is heated to the mixture that 90 ℃ of stirrings form.
Described straw pulp material is a kind of or compound of the dried feed of straw, straw, corn cob, bagasse or annual herb stem leaves of plants, is ground into powder, and in forage: the ratio of water=2: 1 adds boiling water, pours the slurry that paste roller mill is worn into into.
Above-mentioned formula material is joined in the stirrer by the consumption weight part ratio, and the filtration that stirs is injected in the mould, sends into flash baking in the baking oven, promptly becomes the blank of making shopping bag.Specification is cut out on demand, pastes through the edge to form finished product.
The preparation method of this shopping bag comprises the steps:
1, preparation straw pulp material: one or more the mixture in the dried feed of clean straw, straw, corn cob, bagasse or annual herb stem leaves of plants is ground into powdery, with forage: the weight part ratio of water=2: 1 adds boiling water, wears into slurry through paste roller mill;
2, preparation polyvinyl alcohol mucus: by polyvinyl alcohol: the weight part ratio of water=1: 3-4, in polyvinyl alcohol, add the cold water heating, be incubated at 80-100 ℃, be stirred to polyvinyl alcohol and dissolve fully;
3, batching stirs: with polyvinyl alcohol liquid, gypsum, slurry, salt, defoamer, nontoxic water-resisting agent, oil resistance agent by 5: 1: 1: 0.01: 0.01: 0.1: 0.1 weight part ratio, join in the stirrer, stir and filter;
4, base material: filtered liquid is injected in the different moulds, adjust to desired thickness, be sent to baking oven flash baking;
5, paste the edge: the blank of oven dry is cut out by needed specification, and fastening with glue needs the edge of stickup, is the shopping bag of adorning general article through compacting.
In the above-mentioned steps 3,, also can add small amount of coloring matter pigment, to make colored shopping bag or packing of product bag according to needs to color; Described in the step 4 filtered liquid injected in the different moulds and be meant: the filtered liquid extruding must be injected in the cylindric mould during shopping bag made; Filtered liquid must be injected in the tabular mould of rectangle during system packing of product bag.
This shopping bag can also be made the shopping bag of splendid attire food and water, is to stick on one deck non-toxic film at the inner face of general shopping bag to form.
Described glue is the general sticking used glue of paper.
This shopping bag can also be made transparent shopping bag or packing of product bag, be that polyvinyl alcohol liquid is added defoamer and salt, weight part ratio is a polyvinyl alcohol liquid: defoamer: salt=5: 0.01: 0.01 mixing and stirring, inject mould flash baking, and get transparent blank.
Advantage of the present invention is:
1, this packing bag can be degraded, and is environmentally friendly;
2, make raw material be easy to get, cheap;
3, preparation technology is simple, makes easily;
4, recyclable recycling.
