Abstract
The invention discloses a low-humidity antistatic film which is formed by laminating a permanent antistatic agent layer, a polyester layer, a metal coating and an antistatic masterbatch layer. The invention further provides the use of the low-humidity antistatic film for producing electrostatic shield packaging bags of electronic component products or semi-finished products in the electronic industry. With the structure that the outer layer is the low-price permanent antistatic agent layer and the inner layer is the antistatic masterbatch layer, the low-humidity antistatic film can meet the needs for low humidity and electrostatic protection and has a low cost.
Description
Technical field
The present invention relates to a kind of low humidity antistatic film and application thereof, especially relate to a kind of low humidity antistatic film that is applied to make anti-static shielding bag, belong to technical field of polymer materials.
Background technology
Anti-static shielding bag commonly used is to adopt four layers of composite construction of two layers compound or higher mostly in the electron trade.Form faraday cup induction cover effect in the anti-static shielding bag, at utmost article and electrostatic field isolation in the protective bag prevents accumulation of static electricity, avoids electrostatic hazard.Wherein, humidity is one of environmental condition that affects the shielding bag antistatic property, and anti-static material commonly used has common antistatic additive, permanent anti-static agent and antistatic master granule at present.
Common antistatic additive is such as non-ionic antistatic agent and composite antistatic agent.Because the non-ionic antistatic agent thermal stability is good, price is more cheap, easy to use, non-stimulated to skin. be indispensable antistatic additive in the antistatic base material, have a good application prospect, and composite antistatic agent is to utilize the coordinating effect principle of each component to develop, each component is with strong complementarity, antistatic effect is much better than one-component, but these two kinds of antistatic additive antistatic property under low moisture conditions is relatively poor.The development of antistatic master granule is that wherein a part is polar polymer, difficulties in dispersion in plastics because common antistatic additive mostly is thick liquid, cause the inconvenience in the use, and multi-functional concentrated master batch is evenly dispersed, and is easy to operate, but this antistatic master granule price is comparatively expensive.The permanent anti-static agent is a class new anti-static agent of Recent study exploitation, belongs to hydrophilic polymer, but the permanent anti-static agent is because using crosslinking agent can't survey use in antistatic film.
The film material of anti-static shielding bag commonly used mostly is at present: common antistatic additive layer/pet film/aluminium foil layer/polyethylene film/common antistatic additive, or the structure of antistatic master granule/pet film/aluminium foil layer/antistatic master granule, the film material of above-mentioned two kinds of structures all can not satisfy on lower-cost basis the antistatic requirement of low humidity.
Summary of the invention
The objective of the invention is provides a kind of low humidity antistatic film and application thereof in order to solve the problems of the technologies described above, and can be manufactured on by low humidity antistatic film of the present invention to be used for packing electronic component products or half-finished anti-static shielding bag in the electron trade.Technical solution of the present invention is as follows:
A kind of low humidity antistatic film comprises permanent anti-static agent layer, polyester layer, metal coating and the compound formation of antistatic master granule layer successively.
Further, described polyester layer comprises pet film, polybutylene terephthalate film or polyarylate film.
Further, described metal coating is aluminized coating, nickel coating or copper coating.
The present invention also comprises a kind of shielding bag on the other hand, this shielding bag be by described low humidity antistatic film through cut, bag makes.
Technique effect of the present invention is mainly: adopt the comparatively cheap permanent anti-static agent layer of price, internal layer to adopt the antistatic master granule layer by skin, can satisfy the antistatic requirement of low humidity and can reduce cost again.
Description of drawings
Fig. 1 is the structural representation of low humidity antistatic film of the present invention.
The specific embodiment
The present invention will be described below by specific embodiment, for embodiment the present invention is made the generality illustration, help to understand better the present invention, but can't limit the scope of the invention.Material described in the following embodiment if no special instructions, all can obtain from commercial channels.
Particularly, the present embodiment low humidity antistatic film comprises permanent anti-static agent layer 1, polyester layer 2, metal coating 3 and antistatic master granule layer 4 compound formation from outside to inside successively.Described polyester layer 2 is the film that comprises that PETG, polybutylene terephthalate or polyarylate are made, and is preferably pet film.Described metal coating 3 is aluminized coating, nickel coating or copper coating, is preferably aluminized coating.
Permanent anti-static agent of the present invention is a class hydrophilic polymer, after itself and macromolecule matrix blend, because the locomitivity of its strand is stronger, and the intermolecular proton of being convenient to moves, conducts and discharges the electrostatic charge of generation by ionic conduction on the one hand.On the other hand, antistatic effect is to embody by its special dispersing morphology.This permanent antistatic agent mainly is that the stratiform or the muscle shape that are fine on the goods top layer distribute, and consists of the electric conductivity top layer, and almost is spherical distribution at core, forms so-called " core shell structure ", and leaks electrostatic charge as path.Because permanent antistatic agent is to reduce material volume resistivity to reach antistatic effect, not exclusively rely on water absorbent surface, so be subjected to the humidity effect of environment smaller.By adopting comparatively cheap permanent anti-static agent layer 1 skin as the low humidity antistatic film of price, adopting antistatic master granule layer 4 internal layer as the low humidity antistatic film, can satisfy the antistatic requirement of low humidity and can reduce cost again.
More specifically, can adopt conventional method by low humidity antistatic film of the present invention, as cut, bag makes in electron trade and to be used for packing electronic component products or half-finished anti-static shielding bag.
Above-described embodiment does not constitute any limitation protection scope of the present invention, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the scope of protection of present invention.
