Description

The manufacture method and cover strip of cover strip body paper, cover strip body paper
Technical field
The present invention relates to electronic component packaging field, particularly coordinates body paper and lid used by the cover strip for carrying and using Preparation method with body paper.
Background technology
The packaging of electronic component, transport and take etc. and must have corresponding carrier, at present chip electronic member device The packaging of part is that loading hole is got after paperboard is cut, and seals loading bottom hole portion with back cover band, is then placed in slice component, then Loading hole is sealed with cover strip, when use takes the slice component in loading hole when opening cover strip.
Cover strip on the market uses polyester film now（PET film）As base material generally comprise antistatic layer, polyester film layer, Anchor joins agent（Adhesive）The sandwich construction such as layer, associativity resin bed, hot melt adhesive layer.Such as in Patent No. CN103204309A A kind of Tearable cover tape disclosed in state's patent, it includes cover strip body, and the top layer of the cover strip body is substrate layer, cover strip body Bottom be hot sealing layer, transition zone is equipped between polyester layer and hot sealing layer.But due to the physical characteristic of polymer PET itself, it is impossible to With molten state hot melt adhesive layer direct combination, adhesive bond resin bed need to be carried out by adhesive, recycle associativity resin bed with Molten state hot melt adhesive layer is for composite, but leak adhesive phenomenon easily occurs in finished product, causes to be layered.Again since polymer PET easily produces in itself Also need to apply antistatic additive with electrostatic, the easy adhesion of manufactured goods, therefore polyester film surface is carried, above-mentioned technique is not only cumbersome, is added to This, and applied electrostatic agent and adhesive are required to be diluted using solvent, and solvent and adhesive volatilization can be to operator's bodies Body damages；Polymer PET after cover strip use also can not recycling, be unfavorable for environmental protection.
The content of the invention
The purpose of the present invention is to solve leak adhesive, layering existing for existing cover strip, painting antistatic additive technique is cumbersome, increases Addition sheet, but not environmentally the problem of, there is provided a kind of cover strip body paper, can replace cover strip base material, cover strip final product quality is more stable, Electrostatic treatment need not be removed, simplifies technique, it is also more environmentally-friendly.
It is by controlling process conditions, the characteristic of each raw material of body paper is excellent the present invention also provides the preparation method of above-mentioned body paper Gesture is shown, and is improved the tensile strength of body paper and is reduced lateral shrinkage.
The present invention also provides simplified using cover strip made of above-mentioned body paper, stable quality, technique.
In order to achieve the above object, the present invention adopts the following technical scheme that：A kind of cover strip body paper, including superficial layer, bottom Surface layer and the intermediate layer between the superficial layer and the bottom surface layer, the superficial layer are polymer resin layer, intermediate layer Raw material be long fibre wood pulp, bottom surface layer is polymer resin layer.
Above-mentioned technical proposal, by three-layer composite structure, intermediate layer uses long fibre wood pulp, is conducive to improve body paper entirety Tensile strength, control lateral shrinkage, superficial layer and bottom surface layer all use polymer resin layer, it is easier to are covered between carrier band Close, and soft flocks will not be produced, quality is more stable, and intermediate layer also advantageously improves the brightness of cover strip body paper.
Preferably, the raw material in the intermediate layer is needle long fibre wood pulp, with reference to polymer resin layer, thickness is more preferably controlled System, and more other wood pulps, the tensile strength effect of same thickness are more preferable.
Preferably, the principal component of the superficial layer and the bottom surface layer be 50wt%-65wt% modified polyvinylalcohol, The modified polyacrylamide of 30wt%-45wt% and the zirconium carbonate amine of 3wt%-6wt%.The high score subtree that the component of above-mentioned formula is formed Lipid layer, it is more preferable with the amalgamation in intermediate layer, be not in layering, between carrier band to cover performance more stable.
Preferably, the thickness of the superficial layer is 0.5 μm -2 μm.
Still more preferably, the thickness of the superficial layer is 0.5 μm -1.5 μm,
Preferably, the thickness in the intermediate layer is 33 μm -48 μm.
Preferably, thickness deviation≤3% in the intermediate layer.
Preferably, being added in the intermediate layer has auxiliary material, the auxiliary material includes accounting for the long fibre wood pulp weight 0.01%-0.5% auxiliary materials one and account for the long fibre wood pulp weight 0.5%-1.0% auxiliary material two, the auxiliary material one is low molecule At least one of weight polyacrylamide system resin, polyethylene glycol oxide, polyvinyl alcohol resin, wet strengthening resin etc. are several；It is described Auxiliary material two is rosin series resin.
In such scheme, auxiliary material one is conducive to the scattered of long fibre wood pulp and cures so that evenly, quality is more in intermediate layer Stablize, moreover it is possible to improve the attachment force between intermediate layer and superficial layer and bottom surface layer jointly with auxiliary material two, it is not easy to be layered.
Preferably, the rosin series resin is Dispersed Anionic Rosin Size or cationic rosin size.
A kind of preparation method of cover strip body paper, including step：（1）Bleached softwood is starched and carries out pulping, adds 0.5%-1.5% NaOH and 0.1%-0.5%Na2HPO4；Mashing processing is carried out with clear water diluted concentration to 4.0%-4.8% again, until beating degree is at 60 ° SR-75 ° of SR, weight in wet base 5.5g-7.5g；
（2）The slurry concentration being beaten is adjusted to 3.5%-4.5%, pH value is adjusted to 5-7 using aluminum sulfate solution, adds auxiliary Material is uniformly mixed；
（3）Slurry slag removal and purification, formed after disperseing using net forming on fourdrinier wire or the board-like copy paper method of cylinder adjustable arc L Water Paper page；
（4）Squeeze, be dried to water tariff collection in 5%-7%, obtain intermediate layer；
（5）Superficial layer raw material is prepared into superficial layer applicator, bottom surface layer raw material is prepared into bottom surface layer applicator；
（6）Upper surface layer applicator and bottom surface layer applicator is respectively coated in the interlayer surfaces, bottom surface, obtains thickness For the bottom surface layer that 0.5 μm -2 μm of superficial layers and thickness are 0.5 μm -3 μm, then optical pressure, cool down, batch.
By implementing above-mentioned technical proposal, the present invention has the advantage that：
1st, the high bleaching long fibre wood pulp of use intensity ensure that tensile strength and the brightness of body paper；
2nd, auxiliary material is added to reduce the lateral shrinkage of body paper under the high temperature conditions in middle wood pulp long fibre layer, improve wood The uniformity of pulp fibres；
3rd, the transparency of body paper is improved by improving pulp freeness and body paper tightness；
4th, the thickness evenness of body paper, reduce thickness deviation are improved using relatively low online concentration and using auxiliary material.
Overall simplification production technology, reduce production cost, improves cover strip quality, improves operation environment.
