Description
Technical field
The present invention relates to a kind of electronic packaging carrier band, specifically a kind of multiple field plastic carrier.
Background technology
Carrier band refers in a kind of band-type product being applied to electronic packaging field; it has specific thickness; be equally spaced for bearing the pocket of electronic devices and components and the knock hole for carrying out index location in their length direction; cover strip (cover tape) is coordinated to use; by resistance; electric capacity; transistor; the electronic devices and components carryings such as diode are accommodated in the pocket of carrier band; and formed the packaging of closed type by involution cover strip above carrier band, for the protection of electronic devices and components not contaminated and damage in transit.In recent years, the technology relating to electronic unit and electro part carrying goods develops rapidly, specifically, lightweight, miniaturization, multifunction, high precision int Parallel Development simultaneously, this just further improves the mechanical characteristics of carrier band and the requirement of electrical property, on market only as the carrier band born of electronic product, although cost of manufacture is low, obviously cannot meet its special quality requirement.The patent No. is that the Chinese patent of CN101992575 discloses a kind of polycarbonate co on March 30th, 2011, have as the sandwich layer of innermost layer with as outermost two superficial layers, described sandwich layer is formed by the poly carbonate resin composition containing the carbon black of 4 ~ 7 quality % and the inhibiter of 0.1 ~ 2.0 quality %, described superficial layer is formed by the poly carbonate resin composition of the carbon black containing 7 ~ 15 quality %, can be used for width thin (below 8mm), for the electronic component-use carrying belt that uses under severe conditions, greater homogeneity and stable, there is the polycarbonate co of excellent antistatic properties.But it also exists following defect: 1. the primary raw material of sandwich layer and superficial layer is polycarbonate resin, same material is difficult to meet the many-sided function needs of product, too increases the holistic cost of sheet material simultaneously; 2. this disclosure of the invention is a kind of sheet material, and carrier band is sheet material through plastics sucking moulding, punching, the technique such as cuts and obtain, and the condition of its technique also can affect the quality of final carrier band, so sheet material can not represent carrier band completely.
Summary of the invention
The object of this invention is to provide a kind of multiple field plastic carrier, the main performance of different layers is different, and each layer combines the requirement that can meet carrier band various aspects of performance.
In order to achieve the above object, the present invention adopts following technical scheme: a kind of multiple field plastic carrier, comprise the central core of innermost layer and two superficial layers of outermost, described central core with one or more in ABS, PS, PE, PVC for base-material, described central core also add account for described central core base-material weight 10 ~ 15% plasticizer, described superficial layer mixes as base-material using PC or PC composite with one or more in PAN, PPP, PTH and PPV, also adds 1 ~ 5% fire retardant accounting for described superficial layer base-material weight in described superficial layer.
Central core in this invention adopts intensity high, but the plastics of advantage of lower cost are as base-material, and superficial layer adopts performance good, but the base-material that cost is high, make the characteristic of each layer base-material can be complementary, thus ensure the quality of carrier band; Adding of plasticizer can reduce costs under the prerequisite ensureing central core intensity; PAN, PPP, PTH and PPV are all the plastics with electric conductivity, its mix the characteristic that can meet superficial layer tool electric conductivity, and can not because interpolation conductive agent and affect the performances such as the toughness of superficial layer, and obtained carrier band with the use of the involution of cover strip good.
As preferably, be provided with interlayer between described central core and superficial layer, described interlayer is made up of one or more in ABS, PS, PE, PVC, and described interlayer is added with the conductive agent that weight ratio is 0.1 ~ 1%.
As preferably, described interlayer is distributed in the both sides of described central core, is symmetrical arranged.
Due to the characteristic of every layer material and radical function different, relatively described central core is symmetrical arranged, and is conducive to the assurance of carrier band total quality.
As preferably, in the base-material of described central core, also comprise reclaimed materials.
The utilization of reclaimed materials can cut the waste and environmental pollution, and be used in the performance that central core also can not affect carrier band, reclaimed materials can be the rim charge of each layer or detect inferior-quality substandard products etc.
As preferably, described conductive agent is CNT or nano-graphite or the carbon black being coated with PAN or PPP or PTH or PPV.
Conductive black is manufacture the main additive of conductive plastic always, but the variation slightly of the changing a little of amounts of carbon black when adding, production tooling and condition, all can cause the change of electrical resistivity on the order of magnitude, be more difficult to get the product that electrical resistivity is stable.CNT or nano-graphite or the carbon black being coated with PAN or PPP or PTH or PPV all have good electrical resistivity duplicability, especially the carbon black of PAN or PPP or PTH or PPV is coated with, reduce the specific surface area and porosity of carbon black, improve the compatibility between base-material, flowing power and mechanical property are significantly improved.
As preferably, described in the base-material of described superficial layer, PC or PC composite accounts for 60 ~ 70% of base-material total weight, and one or more in described PAN, PPP, PTH and PPV account for 30 ~ 40% of base-material total weight.
Proportioning in this technical scheme in the electrical resistivity meeting carrier needs, can ensure mechanical characteristics again simultaneously, obtains special quality carrier band with low cost.
As preferably, described fire retardant is organic phosphorus flame retardant, and described organic phosphorus flame retardant is phosphonate ester and/or polyphosphate.
Organic phosphorus flame retardant is the fire retardant of the low cigarette of a class, nontoxic, Halogen, preferred phosphonate ester and/or polyphosphate, aboundresources, cheap, but also has fire-retardant and dual-use function that is plasticising.
As preferably, described PC composite comprises the PC of 50 ~ the 75% and PS of 25 ~ 50% and unsaturated dicarboxylic anhydride copolymer, and described unsaturated dicarboxylic anhydride copolymer is relative to 15 ~ 20 weight portions of 100 weight portions of the resin summation of described PC and described PS.
Through the composite that said ratio material obtains, processing fluidity is good, and impact strength is high, ductility is excellent.
By implementing above-mentioned technical scheme, the present invention has following beneficial effect: carrier band provided by the invention, adopt multilayer architecture, and the material that every layer of employing is different, the characteristic of layers of material be combined with each other, complementation, meet the requirement of the aspects such as carrier band mechanical characteristics and electrical property, be easy to involution, greatly reduce productive costs, reclaimed materials can also be utilized simultaneously, cut the waste, decreasing pollution.
