Description
Technical field
The present invention relates to packing explosive technical field of membrane, disclose a kind of blasting charge packaging film and preparation method thereof especially.
Background technology
On the basis of Development of Packaging Industry, the packaging of article is also developed accordingly.From simple paper wrapper, to single layer plastics films packaging, develop into widely using of composite material.The features such as complex film can make package contents have moisturizing, protects fragrant, attractive in appearance, fresh-keeping, lucifuge, impermeable, Shelf-life, thus obtain fast development.
Explosive (Explosive material), can in very short time the material of vigorous combustion (namely explode), be under the effect of certain outside energy, the material of being blasted by self-energy.Explosive, because of its particularity, also has special requirement to its packaging, and obtained official standard " GB 14493-2003 commercial explosive packaging " is specification in addition.
High-barrier, antiseep, safety performance height has become the common requirements of packing explosive film.Chinese patent CN101633422A discloses a kind of composite membrane for packing explosive, and it is made up of upper layer film, mesopelagic layer and lower membrane co-extrusion; Upper layer film is made up of polypropylene and the smooth masterbatch of increasing, and mesopelagic layer is Low Density Polyethylene, and lower membrane is made up of Low Density Polyethylene, linear low density polyethylene, metallocene PE, the smooth masterbatch of increasing.Chinese patent CN202685479U discloses collation package complex film in a kind of explosive, and comprise the first top layer film, mesopelagic layer and the second top layer film, described mesopelagic layer is elastic membrane, solves the technical matters of existing complex film poor mechanical property.Chinese patent CN202987838U discloses a kind of packing explosive composite fluorescent film, thermoplastic resin phosphor film layer, the first adhesive layer, interlayer, the second adhesive layer and thermoplastic resin rete is comprised successively to inner by table, by the first adhesive layer compound between thermoplastic resin phosphor film layer and interlayer, by the second adhesive layer compound between interlayer and thermoplastic resin rete.
Above-mentioned patented technology improves barrier, antiseep row, the safety performance of packing explosive film to a certain extent, but is still weak to the further raising of its mechanical strength, the intermembranous bond properties of three-layer co-extruded PE.
Summary of the invention
The object of the present invention is to provide a kind of blasting charge packaging film, adopt PE film+PET film+PE film three-layer composite structure, and PE film adopt high density polyethylene (HDPE) and linear low density polyethylene composite, improve its mechanical characteristics such as tensile strength and impact strength, reduce costs.
Another object of the present invention is the preparation method providing a kind of blasting charge packaging film, adopt high density polyethylene (HDPE) and the outer PE film of the composite preparation of linear low density polyethylene, again by polyurethane binder by itself and middle layer of PET film compound, manufacture craft is simple, it is good that finished product endures power, dimensionally stable, mechanical characteristics is superior.
The invention provides a kind of blasting charge packaging film, comprise interlayer, it has first surface and second surface; Upper outer membrane, is compound on the first surface of interlayer; Lower outer membrane, is compound on the second surface of interlayer; Wherein, interlayer is PET film.
Polyethylene terephthalate, English name: polyethylene terephthalate, being called for short PET, is high polymers, by ethylene glycol terephthalate generation dehydration condensation.
PET film has another name called high temperature resistance polyester film.Its transparency is good, glossy; There is good air-tightness and fragrance protectiveness; Moisture resistance is medium, and rate of perviousness declines at low temperatures.The good mechanical performance of PET film, its obdurability is best in all thermoplastic plastics, tensile strength and impact strength more much higher than general film; And very power is good, dimensionally stable, is suitable for the secondary processing such as printing, paper bag.PET film also has excellent heat-resisting, resistance to cold and good chemical proofing and fuel resistance.
