Description
Technical field
The present invention relates to a kind of plastics permanent anti-static composition and method of making the same, particularly, the present invention relates to polymer-type permanent anti-static composition and method of making the same for a kind of plastics.
Background technology
Most of macromolecular materials easily produce accumulation of static electricity in producing and using, thereby cause the bad phenomenon such as electrostatic precipitation, static discharge.When serious, can produce spark, cause fire or blast, make troubles to 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 Ω, electroconductibility extreme difference easily produces static and is difficult for leading away in packed and transported process, and product is caused to very large harm.Along with the increasingly extensive application of static inhibitor, the performance of static inhibitor has also been proposed to more and more higher requirement.
Plastics are the widely used high molecular synthetic materials of modern society, it have very high surface resistivity (25 ℃, RH60%, resistivity 10
17Ω).Thereby, once after frictional electrification, static is difficult for being removed and being trapped in frosting by conduction.Due to the existence of static, not only affect (dust suction etc.) attractive in appearance of plastics, main is manufacture and the use that affects plastics.Plastic wrapping static inhibitor reduces Polymer Surface resistivity and electric density for plastics face, thereby reaches the object of removing static hazard.
When plastics and product surface resistance: very easily produce static while being greater than 10 power; Between 8-10 power, there is certain antistatic performance; Between 6-8 power, there is good antistatic performance; Between 4-6 power, there is best antistatic performance; When reaching 4 powers, there is below suitable conductivity, belonged to conductor semiconductor material.
Traditional static inhibitor is comprised of micromolecular surfactant, and it contains hydrophilic radical and lipophilic group.Because it is not exclusively compatible with resin itself, so static inhibitor can be from resin internal migration to resin surface.Traditional static inhibitor need to can work under certain humidity condition, and its hydrophilic radical can promote that frosting is moistening by water, thus conduct static lotus, the surface resistivity of reduction plastics.Only have and behind surface, just can work when traditional static inhibitor molecular migration, the static inhibitor molecule of plastics inner moves about to surface, until completely consumed, thereby its action effect only within the scope of certain hour effectively.
Polymer permanent antistatic agent can only join in base-material by mixing method.It is not by migrating to frosting, but lean against plastics inner, forms a Percolation Network with conductive capability, as path, takes off surface and intrinsic static charge, reduces resistivity.Compare with traditional static inhibitor, its antistatic effect is lasting, without inductive phase, not affected by the conditions 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 affected by it.
Polymer permanent antistatic agent is a class new anti-static agent of Recent study exploitation, belongs to hydrophilic polymer.After itself and macromolecule matrix blend, on the one hand because the motor capacity of its molecular chain is stronger, the intermolecular proton of being convenient to moves, and is conducted and is discharged the static charge of generation by ionic conduction; On the other hand, antistatic effect is to embody by its special dispersing morphology.Research shows, polymer permanent antistatic agent is mainly that the stratiform or the muscle shape that on goods top layer, are fine distribute, and forms electroconductibility top layer, and is almost spherical distribution at centre portions, forms so-called " core shell structure ", and leaks static charge as path.Because polymer permanent antistatic agent is to reduce material volume resistivity to reach antistatic effect, not exclusively rely on water absorbent surface, so be subject to the humidity effect of environment smaller.Compare with traditional static inhibitor, the electric charge that these hydrophilic polymers can not only releaser surface, can also discharge the electric charge of interior of articles, therefore can reduce surface resistivity and the volume resistance of object simultaneously.
CN102051156A discloses a kind of poly-bacteria ether family macromolecule static inhibitor, and it is mainly prepared by the raw material of following weight part: 100 parts of poly glycol monomethyl ether methacrylic vinegars, methyl methacrylate vinegar 30-250 part, sodium methacrylate or methacrylic acid and sodium carbonate mixture 2-50 part, water glass 1-30 part and AIBNO.1-5 part.This invention does not adopt unstable and poisonous sodium perchlorate, make production process environmental protection more, in addition this invention has also improved the heatproof characteristic of product, has expanded use range, can be applicable in the material such as PET, PA, PB, PE, PP, PS, ABS, PVC, PLA of anti-electrostatic.
CN1326922C discloses a kind of static resistant polyamide composition, said composition contains at least one polyamide and makes it become anlistatig enough carbon blacks, and this carbon black is that at least one is selected from the carbon black with following characteristic: according to the BET specific surface of ASTM D 3037-89 standard test, be 5-200 rice
2/ gram, according to the DBP of ASTMD2414-90 standard test, be absorbed as 50-300 milliliter/100 gram.
