Abstract
The utility model discloses a composite sheet for an environment-friendly composite glue modified polrvinyl chloride (PVC)-polyvinylidene chloride (PVDC) drug. The composite sheet comprises a supporting layer and a separating layer, wherein the separating layer is arranged on the supporting layer; the supporting layer is a polrvinyl chloride layer, and the separating layer is a polyvinylidene chloride layer; an alcohol-water type composite adhesive layer is arranged between the polrvinyl chloride layer and the polyvinylidene chloride layer; the alcohol-water type composite adhesive layer is composed of an aqueous polyurethane tackifier layer and a grafted co-polymer modified alcohol solvent type polyacrylate adhesive layer. The composite sheet for the PVC/PVDC drug is produced by compounding, bonding, modifying the alcohol-water type composite adhesive layer, thus the production of the composite sheet product for the PVC/PVDC drug cannot pollute environment, and the hygienic safety of the composite sheet product is improved; and meanwhile, the quality index of the ultraviolet absorption degree of the composite sheet product is reduced by multiple times, and the quality preserving property of the composite sheet on the packed drug is enhanced.
Description
Technical field
The utility model relates to a kind of medicinal composite sheet, particularly relates to the medicinal composite sheet of a kind of environmental protection compound adhesive modified polyvinyl chloride-polyvinylidene chloride.
Background technology
For a long time, the production of polyvinyl chloride-polyvinylidene chloride (PVC/PVDC) solid medicinal composite sheet all is that pure organic ethyl acetate or toluene kind solvent type dual-component polyurethane (PU) adhesive that adopts non-Environmental Safety made the primary coat adhesives, polyvinylidene chloride (PVDC) emulsion is coated with the crystalline film material as face.Because pure organic ethyl acetate of basecoat material or toluene kind solvent type dual-component polyurethane adhesive are poisonous free isocyanate (TDI) monomer components that contains poisonous, inflammable unsafe organic ethyl acetate or toluene kind solvent and trace; Cause environmental pollution not only for the production of the medicinal composite sheet of PVC/PVDC; Cause influence to a certain degree also can for the sanitary toxicology character amount of composite sheet product, also can make the ultraviolet absorptivity quality index superelevation of composite sheet product simultaneously because of the amino group in the polyurethane.
The utility model content
The purpose of the utility model is the medicinal composite sheet of environmental protection compound adhesive modified polyvinyl chloride-polyvinylidene chloride that the environmental pollution that provides a kind of production to cause in order to address the above problem is little, the air barriering effect is good.
The utility model is realized through following technical scheme:
The medicinal composite sheet of a kind of environmental protection compound adhesive modified polyvinyl chloride-polyvinylidene chloride; Comprise supporting layer and barrier layer; Said barrier layer is arranged on the said supporting layer; Said supporting layer is a polyvinyl chloride layer, and said barrier layer is the polyvinylidene chloride layer, is provided with alcohol-water type composite adhesive layer between said polyvinyl chloride layer and the polyvinylidene chloride layer.
Adopt the alcohol-water type composite adhesive, apply the compound sticking modification and produce the medicinal composite sheet of PVC/PVDC, just overcome above-mentioned defective fully.The production that not only makes the medicinal composite sheet product of PVC/PVDC is contaminated environment no longer, and the wholesomeness of composite sheet product is improved greatly; Also make simultaneously the ultraviolet absorptivity quality index of composite sheet product reduce several times, strengthened the guaranteeing the quality property of this composite sheet greatly the packing medicine.
Further improvement as the utility model is that said alcohol-water type composite adhesive layer is made up of aqueous polyurethane tackifier layer grafting, copolymerization and modification spirit solvent type polyacrylate adhesive layer.
Further improvement as the utility model is that the thickness of said polyvinyl chloride layer is 0.1-0.5mm.
Further improvement as the utility model is that the thickness of said polyvinylidene chloride layer is 0.02-0.2mm.
Further improvement as the utility model is that the thickness of said alcohol-water type composite adhesive layer is 0.01-0.05mm.
The beneficial effect of the utility model is:
Adopt the modification of alcohol-water type composite adhesive compound sticking to produce the medicinal composite sheet of PVC/PVDC, the production that not only makes the medicinal composite sheet product of PVC/PVDC is contaminated environment no longer, and the wholesomeness of composite sheet product is improved greatly; Also make simultaneously the ultraviolet absorptivity quality index of composite sheet product reduce several times, strengthened the guaranteeing the quality property of this composite sheet the packing medicine.

Among the figure: 1-composite sheet, 2-supporting layer, 3-barrier layer, 4-alcohol-water type composite adhesive layer.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify:
As depicted in figs. 1 and 2; The medicinal composite sheet 1 of the utility model environmental protection compound adhesive modified polyvinyl chloride-polyvinylidene chloride; Comprise supporting layer 2 and barrier layer 3, barrier layer 3 is arranged on the supporting layer 2, and supporting layer 2 is a polyvinyl chloride layer; Barrier layer 3 is the polyvinylidene chloride layer, is provided with alcohol-water type composite adhesive layer 4 between polyvinyl chloride layer and the polyvinylidene chloride layer.Alcohol-water type composite adhesive layer 4 is made up of aqueous polyurethane tackifier layer grafting, copolymerization and modification spirit solvent type polyacrylate adhesive layer.Adopt the alcohol-water type composite adhesive, apply the compound sticking modification and produce the medicinal composite sheet of PVC/PVDC, the production that not only makes the medicinal composite sheet product of PVC/PVDC is contaminated environment no longer, and the wholesomeness of composite sheet product is improved greatly; Also make simultaneously the ultraviolet absorptivity quality index of composite sheet product reduce several times, strengthened the guaranteeing the quality property of this composite sheet the packing medicine.The thickness of polyvinyl chloride layer is 0.1-0.5mm.The thickness of polyvinylidene chloride layer is 0.02-0.2mm, and the thickness of alcohol-water type composite adhesive layer is 0.01-0.05mm.
It should be noted last that above embodiment is only unrestricted in order to the technical scheme of explanation the utility model.Although the utility model is specified with reference to embodiment; Those of ordinary skill in the art is to be understood that; The technical scheme of the utility model is made amendment or is equal to replacement; The spirit and the scope that do not break away from the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
