Description
Technical field
The present invention relates to a kind of plastics and use the permanent anti-static composition and method of making the same, particularly, the present invention relates to a kind of plastics with polymer-type permanent anti-static composition and method of making the same.
Background technology
Most of macromolecular materials are prone to produce accumulation of static electricity in producing and using, thereby cause bad phenomenon such as electrostatic precipitation, static discharge.Can produce spark when serious, cause fire or blast, make troubles for industrial production and daily life.
Current, plastic prod is widely used as wrapping material etc., but common frosting resistance is all greater than 10
12More than the Ω, the electroconductibility extreme difference be prone to produce static and is difficult for leading away in the packed and transported process, product is caused very big harm.Along with the increasingly extensive application of static inhibitor, increasingly high requirement has been proposed also for the performance of static inhibitor.
Plastics are the widely used high molecular synthetic materials of modern society, it have very high surface resistivity (25 ℃, RH60%, resistivity 10
17Ω).Thereby, in case after the frictional electrification, difficult the removing through conduction of static is trapped in frosting.Because electrostatic exists, and not only influences (dust suction etc.) attractive in appearance of plastics, main is manufacturing and the use that influences plastics.The plastic wrapping static inhibitor is used for the plastics face and reduces Polymer Surface resistivity and electric density, thereby reaches the purpose of removing static hazard.
When plastics and product surface resistance: very easily produce static during greater than 10 powers; Between the 8-10 power, has certain antistatic performance; Good antistatic performance is arranged between the 6-8 power; Between the 4-6 power, has best antistatic performance; Had suitable conductivity below 4 powers when reaching, belonged to the conductor semiconductor material.
Traditional static inhibitor is made up of the micromolecular promoting agent that shows, it contains hydrophilic radical and lipophilic group.Because it is not exclusively compatible with resin itself, so static inhibitor can be from the resin internal migration to resin surface.Traditional static inhibitor need can work under the certain humidity condition, and its hydrophilic radical can promote that frosting is moistening by water, thus the conduct static lotus, the surface resistivity of reduction plastics.Have only when traditional static inhibitor molecular migration and behind the surface, just can work, the static inhibitor molecule of plastics inner moves about to the surface, until completely consumed, thereby its action effect only in the certain hour scope effectively.
The polymer permanent antistatic agent can only join in the base-material through mixing method.It is not by migrating to frosting, form the diafiltration network with conductive capability but lean against plastics inner, take off surface and intrinsic static charge as path, reducing resistivity.Compare with traditional static inhibitor, its antistatic effect is lasting, no inductive phase, does not receive condition influence such as wiping and washing; Because its conductivity does not reach by water layer, thus little to the relative humidity dependency of air, and the mechanical property of goods and resistance toheat are not influenced by it.
The polymer permanent antistatic agent is one type of new anti-static agent of Recent study exploitation, belongs to hydrophilic polymer.When its with the macromolecule matrix blend after, on the one hand, conduct and discharge the static charge of generation through ionic conduction because the motor capacity of its molecular chain is stronger, and the intermolecular proton of being convenient to moves; On the other hand, antistatic effect is to embody through its special dispersing morphology.Research shows that the polymer permanent antistatic agent mainly is that the stratiform or the muscle shape that are fine on the goods top layer distribute, and constitutes the electroconductibility top layer, and almost is spherical distribution at centre portions, forms so-called " core shell structure ", and leaks static charge as path.Because the polymer permanent antistatic agent is to reach antistatic effect to reduce material volume resistivity, not exclusively rely on water absorbent surface, so receive the humidity effect of environment smaller.Compare with traditional static inhibitor, the electric charge that these hydrophilic polymers can not only the releaser surface can also discharge the electric charge of interior of articles, therefore can reduce object surfaces resistance and volume resistance simultaneously.
