Abstract
The present invention relates to one and both there is foaming layer function in bottle mouth sealing pad, there is again functional bottle mouth sealing pad intermediate and the manufacture method of hot sealing layer function in bottle mouth sealing pad, foaming layer and hot sealing layer hot melt adhesive in bottle mouth sealing pad in bottle mouth sealing pad.Advantage: one is both to have had foaming layer function in bottle mouth sealing pad, has again hot sealing layer function in bottle mouth sealing pad；Two is to change the layer structure of bottle mouth sealing pad in background technology, makes aluminium foil layer directly and polyester is combined, and thin by functional layer thickness; not only make electromagnetic induction efficiency high; and the power needed for reducing electromagnetic induction, both protecting environment, favourable people operates the healthy of employee again.
Description
Technical field
The present invention relates to one and both there is foaming layer function in bottle mouth sealing pad, there is again functional bottle mouth sealing pad intermediate and the manufacture method of hot sealing layer function in bottle mouth sealing pad, belong to one layer in the middle of bottle mouth sealing pad and manufacture field.
Background technology
CN1970289A, title " high air tightness foamed PE composite gasket ", be mutually glued successively by foaming PE, art paper, aluminium foil, these four layers of materials of polyvinylidene chloride.The main component of pad is foaming PE material, has the elasticity of height, can meet the size between various different bottle mouth, ensures sealing effectiveness.Its weak point: the foaming PE layer in this Composition spacer and polyvinylidene chloride are only layer respectively, adopt and be combined with each other by aluminium foil and binding agent, not only complex process, manufacturing cost is high, and made spacer thickness is thick, and during Electromagnetic Heating, heat conduction efficiency is low, thus result in electromagnetic induction heating power big, energy consumption is high, to environment, directly affects the healthy of operative employee.
Summary of the invention
Purpose of design: avoid the weak point in background technology, designs and a kind of foaming layer and both hot sealing layers unified and have that thickness is thin, conduction of heat is fast, electromagnetic heating power is low, energy consumption is little, reduce amount of electromagnetic radiation and the functional bottle mouth sealing pad intermediate of low cost of manufacture and manufacture method.
Design: in order to realize above-mentioned purpose of design.In bottle mouth sealing pad, foaming layer and the design of hot sealing layer hot melt adhesive in bottle mouth sealing pad, be the technical characteristics of the present invention.So purpose of design is: owing to the application foaming layer is polyethylene foam layer, and polyethylene is typical thermoplastic, it has good hot melt affinity with polyolefin layer hot sealing layer, the present invention utilizes both affine features, two multiple being integrated by compound die are obtained functional bottle mouth sealing pad intermediate, not only there is the function of foaming layer, and there is the function of hot sealing layer, the more important thing is to mold the two copolymerization and be integrated, not only it is combined without bonding agent, and reduce the thickness of seal gasket, the electromagnetic induction power making seal gasket required during sealing reduces, energy consumption reduces, amount of electromagnetic radiation weakens, both environment had been protected, favourable people operates the healthy of employee again.
Technical scheme 1: a kind of functional bottle mouth sealing pad intermediate, foaming layer and hot sealing layer hot melt adhesive in bottle mouth sealing pad in bottle mouth sealing pad.
Technical scheme 2: the manufacture method of a kind of functional bottle mouth sealing pad intermediate, first by polyethylene foam, then the polyethylene melt after foaming and polyolefin molten mass are respectively implanted in compound die in polyethylene die cavity and polyolefin die cavity, then polyethylene and polyolefin are extruded by composite die moulded head, i.e. available one side be polyethylene foam face, one side be the functional bottle mouth sealing pad intermediate in polyolefin face.
The present invention is compared with background technology, and one is both to have had foaming layer function in bottle mouth sealing pad, has again hot sealing layer function in bottle mouth sealing pad；Two is to change the layer structure of bottle mouth sealing pad in background technology, makes aluminium foil layer directly and polyester is combined, and thin by functional layer thickness; not only make electromagnetic induction efficiency high; and the power needed for reducing electromagnetic induction, both protecting environment, favourable people operates the healthy of employee again.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of functional bottle mouth sealing pad intermediate.
Fig. 2 is the structural representation of the bottle mouth sealing pad being made up of Fig. 1.
Detailed description of the invention
Embodiment 1: referring to the drawings 1.A kind of functional bottle mouth sealing pad intermediate, foaming layer 1 and hot sealing layer 2 hot melt adhesive in bottle mouth sealing pad in bottle mouth sealing pad.Described foaming layer 1 is polyethylene foam layer.Described hot sealing layer 2 is polyolefin layer.
Embodiment 2: referring to the drawings 2.On the basis of embodiment 1, aluminium foil 4 two sides is combined with bottle mouth sealing pad surface layer (polyester layer) 3 and functional bottle mouth sealing pad intermediate (1,2) respectively.
Embodiment 3: on the basis of embodiment 1 or 2, a kind of manufacture method of functional bottle mouth sealing pad intermediate, first by polyethylene foam, then the polyethylene melt after foaming and polyolefin molten mass are respectively implanted in compound die in polyethylene die cavity and polyolefin die cavity, then polyethylene and polyolefin are extruded by composite die moulded head, i.e. available one side be polyethylene foam face, one side be the functional bottle mouth sealing pad intermediate in polyolefin face.
It is to be understood that: although the word that the mentality of designing of the present invention is contrasted detailed by above-described embodiment describes; but these words describe; simply the simple text of mentality of designing of the present invention is described; rather than the restriction to mentality of designing of the present invention; any combination without departing from mentality of designing of the present invention, increase or revise, each falling within protection scope of the present invention.
