Abstract
The invention relates to a preparation method for polylactic acid spunbonded non-woven fabric for advertising inkjet printing, belonging to the technical field of spunbonded non-woven fabric. The technical process of the preparation method for polylactic acid spunbonded non-woven fabric for advertising inkjet printing comprises the following steps: (1) drying polylactic acid: cutting the polylactic acid into slices for drying; (2) spinning polylactic acid: manufacturing by an extruder, controlling the temperature, the spinning speed, the stretch ratio and the wet-laying apron speed to spin polylactic acid to obtain spunbonded wires; (3) reinforcing fiber web: preparing the polylactic acid spunbonded non-woven fabric in a fiber web reinforcing way; and (4) plasticizing and forming: uniformly coating liquid PVC (polyvinyl chloride) pulp on the front and back surfaces of the polylactic acid spunbonded non-woven fabric by a scraping knife, then drying, plasticizing and forming to obtain the polylactic acid spunbonded non-woven fabric for advertising inkjet printing. The preparation method has the advantages of being simple in technique, stable in property, rapid in preparation, good in product flexibility, uniform in light permeating, convenient to cut and joint, natural in raw materials, vivid in inkjet printing effect and excellent in hyperplane effect, and being environment-friendly.
Description
Technical field
The invention belongs to spunbond nonwoven fabric technical field, particularly relate to the preparation method of a kind of advertising painting with the spunbond nonwoven fabric of PLA.
Background technology
At present, the advertising painting material should have bright in luster, elegant in appearance, small investment, instant effect, be prone to suspension, easily changeable characteristics.Traditional advertising painting cloth can be under some factor affecting as: weather, dust storm, ultraviolet ray, pollution, bacterium, dust, artificial light etc. all can produce the advertising painting picture effect and threaten.If the unstable properties of the ink that uses in the air brushing process own, the perhaps absorbency difference of advertisement consumptive material, under the influence of extraneous factors such as ultraviolet ray, dust, pollution, the decolouring phenomenon appears in the advertisement meeting.If in the air brushing cloth, insufficient strength, the programming structure of fabric are bad, and under the compound action of dust storm or other extraneous factors, the outer surface of cloth also may occur damaging, tear or phenomenon such as distortion.Simultaneously, existing advertising painting material is main with the raw material (like polyester, polypropylene etc.) of oil, and discarded back soil buries and can not decompose, and burns and can produce great amount of carbon dioxide and toxic and harmful, has dependent resource consumption and causes problem such as environmental pollution.
Summary of the invention
The technical problem of the present invention for existing in the solution known technology, and the preparation method of a kind of advertising painting with the spunbond nonwoven fabric of PLA is provided.
The purpose of this invention is to provide that a kind of to have technology simple, stable performance is made rapidly; The product pliability is good, printing opacity is even, is convenient to cut apart, splice, and it is natural that raw material is got, with environmental friendliness; The air brushing effect is lively, and the advertising painting of characteristics such as hyperplane effect excellence is with the preparation method of the spunbond nonwoven fabric of PLA.
The technical scheme that advertising painting of the present invention uses the preparation method of the spunbond nonwoven fabric of PLA to take for the problem that solves the prior art existence is:
A kind of advertising painting is characterized in the preparation process of the spunbond nonwoven fabric of PLA with the preparation method of the spunbond nonwoven fabric of PLA:
1. PLA is dry
Polylactic acid slice is carried out drying;
2. PLA spinning
Adopt extruder to process, control temperature, spinning speed, draw ratio and lapping curtain speed are carried out the PLA spinning and are obtained spunbond line;
3. fibre web
Adopt the fibre web reinforcing mode to prepare the PLA spun-bonded non-woven;
4. plasticizing forming
Liquid PVC slurry is evenly coated the tow sides of PLA spun-bonded non-woven with scraper, dries plasticizing forming then, obtains advertising painting with the spunbond nonwoven fabric of PLA.
Advertising painting of the present invention can also adopt following technical measures with the preparation method of the spunbond nonwoven fabric of PLA:
Described advertising painting is characterized in the preparation method of the spunbond nonwoven fabric of PLA: PLA is the compound that from corn, extracts.
Described advertising painting is characterized in the preparation method of the spunbond nonwoven fabric of PLA: during the spinning of polylactic acid poly lactic acid, the extrusion temperature that extruder carries out process is 180～204 ℃, and the spinnerets temperature of extruder is 200～230 ℃.
Described advertising painting is characterized in the preparation method of the spunbond nonwoven fabric of PLA: during the spinning of polylactic acid poly lactic acid, extruder carries out the air velocity 3630～7430m/min of process.
Advantage and good effect that the present invention has are:
Owing to adopted brand-new technology scheme of the present invention, compared with prior art, it is simple that the present invention has technology with the preparation method of the spunbond nonwoven fabric of PLA for advertising painting, and stable operation is made rapidly; Product material has that pliability is good, printing opacity is even, is convenient to cut apart, splices, consigns, and outdoor installation is simple; It is natural that raw material is all got; Human body and environment are not had any murder by poisoning, and use and environmental friendliness can adopt the soil method of burying to handle after discarding; Can not cause environmental pollution, have the protection of resources effect; The advertising painting effect is lively, advantages such as hyperplane effect excellence.
The specific embodiment
For further understanding technology contents of the present invention, characteristics and effect, the following examples of giving an example now specify as follows:
Embodiment 1
A kind of advertising painting is with the preparation method of the spunbond nonwoven fabric of PLA, and its technical process comprises:
