Description
Technical field
The invention belongs to the packaging field of electronic devices and components, relate to a kind of paper carrying belt cover strip.
Background technology
The transport of electronic devices and components and use, it is generally required to use packaging supporting body, supporting body typically have paper carrying belt or
Plastic carrier, carrier band is provided with the pocket of electronic devices and components shape, with housing electronic components and parts.After having received, table on carrier band
Face is both needed to cover one layer of cover strip, and to prevent the electronic devices and components of carrier band storage from escaping out, also protection electronic devices and components are not by outward
The interference of boundary's dust and electrostatic etc.；Cover strip had both needed can be with storage carrier band face seal, again when using electronic devices and components
Mutually can peel off with storage carrier band surface.A kind of electronic devices and components storage as disclosed in Application No. 201510335854X carries
The packaging belt of band, including substrate layer, stabilized zone, articulamentum, intermediate layer and general adhesive layer, can be with the surface of storage carrier band
Heat-sealing, can control again certain peeling force, peel away packaging belt when needed, expose electronic devices and components；Making of packaging belt
Also stable by performance, do not have cracking, the situation of quick-fried band during curling.It is primarily directed to receive moulding of electronic components and parts
Material carrier band, and for paper carrying belt, adhesive layer resin is squeezed and easily penetrates in paper fiber.When taking components and parts, cover strip need to be shelled
From paper carrying belt, peeling force the most also pull-up can carry paper fiber (because during sealing before, resin penetrates in paper fiber), causes hair
Bits phenomenon, and general soft flocks size is more than components and parts, therefore can block the pocket of carrier band storage components and parts, affects taking of chip mounter
With.And the general adhesive layer in above-mentioned patent is to paper carrying belt inapplicable, attachment force and peeling force are the most undesirable.
Summary of the invention
It is an object of the invention to for paper carrying belt, it is provided that a kind of cover strip, use cohesion stripping, the first functional layer during stripping
Separating with the second functional layer, the second functional layer remains on carrier band, solves pull-up paper fiber problem and does not affect components and parts
Take.
In order to achieve the above object, the present invention adopts the following technical scheme that:
For encapsulating the cover strip of paper carrying belt, including:
For forming cover strip main body and providing the substrate layer of support strength；
It is positioned on described substrate layer and for strengthening the intermediate layer of cover strip toughness；
It is coated in the first functional layer on described intermediate layer；
Cover the second functional layer on described first functional layer, and the company between described first functional layer and the second functional layer
Relay is less than the attachment force between the second functional layer and paper carrying belt；
The main constituent of described first functional layer is ethylene propylene copolymer and polystyrene and polybutadiene is hydrogenated with the second obtained
Alkene-butylene is the linear three embedding copolymers of middle spring block；
Described second functional layer includes nano tin oxide and antimony mixture, wax, SEBS, acrylate.
Technique scheme, by setting the first functional layer and the second functional layer, the second functional layer and the paper of specific components
There is between matter carrier band stable attachment force, and attachment force is more than the attachment force between the first functional layer and the second functional layer, stripping
From time the second functional layer remain on carrier band, solve pull-up paper fiber problem and do not affect taking of components and parts；
Paper carrying belt is different from plastic carrier, thus second functional layer need specific component formula, the formula in this programme with
Adhesion between paper fiber is good, and has heat-sealing bonding function, it is possible to realize cover strip low temperature fast sealing, the wax meeting of interpolation
Migrate to surface, prevent cover strip surface from boning.First functional layer coordinates with the second functional layer, has certain company between both
Relay, and to ensure that attachment force between the two is less than the attachment force between the second functional layer and paper carrying belt.
And first and second functional layer improves cover strip softening point to a certain extent, do not have under hot and humid and melt
Glue phenomenon.
As preferably, the main constituent of described first functional layer includes: ethylene propylene copolymer 20 mass %-60 mass %, poly-
Styrene and polybutadiene are hydrogenated with the linear three embedding copolymer 40 mass %-80 matter that Ethylene/Butylene is middle spring block obtained
Amount %.
As preferably, the weight portion that the described second each composition of functional layer adds is as follows: nano tin oxide and the mixing of antimony
Thing 0.5-1.5 part, wax 0.1-0.5 part；SEBS 50-75 part, acrylate 10-25 part.
As preferably, nano tin oxide is 80-95:5 with the mixing ratio of antimony.
As preferably, described wax is polyester wax, and anti-stick effect is more preferable.
As preferably, described intermediate layer is ethylene methyl acrylate copolymer layer, by increasing capacitance it is possible to increase cover strip overall flexibility, even if
There is good tensile resistance degree, the most easily broken.
As preferably, the thickness in described intermediate layer is 8 μm-16 μm.
As preferably, the thickness of described second functional layer is 1 μm-2 μm.
By implementing technique scheme, the present invention has a following beneficial effect: the present invention is by selecting suitable the
One functional layer and the second functional layer, have a stable attachment force between the second functional layer and paper carrying belt, and attachment force is more than the
Attachment force between one functional layer and the second functional layer, during stripping, the second functional layer remains on carrier band, solves pull-up paper fine
Dimension problem and do not affect taking of components and parts；And improve cover strip softening point to a certain extent, do not have under hot and humid
Melt glue phenomenon.
