Abstract
The utility model discloses a liquid pesticide packing bottle seal gasket, comprising an outer layer, an inner layer and a bonding layer between the outer layer and an inner layer. The outer layer is ethylene-vinyl acetate copolymer, the inner layer is modified polypropylene film, and the bonding layer is polyester urethane. The outer layer has good anti-corrosion of pesticide and good flexibility, thereby guaranteeing that the combination between the seal gasket and the bottle body after the bottle cover is fastened is tighter than common PE material seal gasket; and the modified polypropylene film at the inner layer is directly contacted with the pesticide with perfect pesticide-resistance penetrating quality, thereby preventing the pesticide from penetrating the bottle cover through the gasket and having better barrier performance outside the bottle; the bonding layer uses polyester urethane, thereby effectively guaranteeing that the inner and the outer layers cannot fall off even at the condition that the pesticide is eroded for a long time.
Description
Technical field
The utility model relates to a kind of gasket seal, particularly a kind of gasket seal of liquid pesticidal Packaging Bottle.
Background technology
Agricultural chemicals generally is to use glass bottle to pack more at present, and glass bottle itself can play good sealing function, but its bottleneck portion then is difficult to effective seal.Adopt more bottleneck encapsulating method to be divided into three kinds now, comprise mode, the mode of aluminium foil sealing and the mode that in bottle cap, installs packing seal additional that Nei Sai combines with enclosing cover, but all exist the problem that the agricultural chemicals resting period can cause the leak tightness variation when longer with upper type.As the mode that plug combines with enclosing cover in adopting, because interior plug need adopt whippy elastomeric material to make, and elastomeric material is easy to be had the agricultural chemicals than the deep-etching effect to corrode, and causes agricultural chemicals poorly sealed after depositing a period of time.And aluminium foil sealing is corroded by the highly acid agricultural chemicals of part too easily.And the gasket seal mode is installed in employing additional in bottle cap, all is to adopt monolayer polyethylene (PE) material as pad, because the PE material can not prevent the agricultural chemicals infiltration by actv., causes agricultural chemicals to volatilize after penetrating packing seal, influences preservation effect.
The utility model content
For solving existing agricultural chemicals glass bottle sealing means can not guarantee sealing effectiveness effectively under long-time situation about storing shortcoming, the utility model provides the long-time storage of a kind of warp and still can guarantee that the sealing of pesticides packaging bottle is reliable by actv., and liquid pesticidal Packaging Bottle gasket seal simple in structure.
For realizing above-mentioned technique effect, a kind of liquid pesticidal Packaging Bottle gasket seal provided by the utility model is made up of the bonding coat in the middle of skin, internal layer and skin and the internal layer.
Above-mentioned a kind of liquid pesticidal Packaging Bottle gasket seal, its described skin is an Ethylene vinyl accetate copolymer, and internal layer is the modified polypropene film, and bonding coat is a PAUR.
Technique effect of the present utility model is, adopt the gasket seal structure of outer Ethylene vinyl accetate copolymer and internal layer modified polypropene film, the anti-agricultural chemicals corrosive property of outer Ethylene vinyl accetate copolymer is good, and it is flexible good, gasket seal is tighter than common PE material seal pad with combining of bottle after having guaranteed to tighten bottle cap, and internal layer modified polypropene film is as the one side of direct contact medicine, its anti-agricultural chemicals penetrating quality is splendid, prevent that agricultural chemicals is penetrated into bottle cap by bed course and the outer barrier of bottle is better, bonding coat adopts PAUR, even effectively guaranteed to be in for a long time under the situation of corrosion of agricultural chemicals, ectonexine can not come off in layering yet.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model, and wherein 1 is Ethylene vinyl accetate copolymer, and 2 is PAUR, and 3 is the modified polypropene film.
The specific embodiment
Referring to Fig. 1, of the present utility model outer 1 is surface band microporous foam, flexible good Ethylene vinyl accetate copolymer (EVA), and the anti-strong acid of EVA material, and anti-solvent, anti-DMF can effectively prevent the agricultural chemicals corrosion.Internal layer 2 is the splendid modified polypropene film (RCPP) of anti-agricultural chemicals penetrating quality, internal layer and outer bonding by the bonding coat between them 3.For actv. strengthens internal layer 2 and outer 1 adhesive ability, prevent from simultaneously to be corroded the problem that makes internal layer 2 outer 1 separation because of bonding coat 3 by agricultural chemicals in long-time storage back, bonding coat 3 has adopted PAUR.When producing the utility model product, it is compound to utilize the plastic sheeting compounding machine to carry out earlier, then solidifying and setting.Again above-mentioned composite material is cut into type in the punch press upper punch, makes needed specification promptly.The thickness of the utility model skin 1 is 0.5mm-1.00mm, and the thickness of internal layer 2 is 0.02mm-0.05mm, and the thickness of bonding coat 3 is 0.005-0.01mm.
Claims (2)
1. a liquid pesticidal Packaging Bottle gasket seal is characterized in that, described pad is made up of the bonding coat (3) in the middle of outer (1), internal layer (2) and outer and the internal layer.
2. a kind of liquid pesticidal Packaging Bottle gasket seal according to claim 1 is characterized in that described skin (1) is an Ethylene vinyl accetate copolymer, and internal layer (2) is the modified polypropene film, and bonding coat (3) is a PAUR.
