Description
Technical field
The invention belongs to plastic processing processing technology fields, and in particular to a kind of plastics high stability antistatic agent adds
Work method.
Background technique
Most of high molecular materials accumulation easy to produce static electricity in production and use, so that electrostatic precipitation, electrostatic be caused to put
The bad phenomenons such as electricity.It can produce spark when serious, cause fire or explosion, make troubles to industrial production and daily life.
Currently, plastic product is widely used in people's lives, and common frosting resistance is all larger than 1012Ω or more,
Electric conductivity is very poor, easy to produce static electricity during packed and transported and be not easy to guide, and very big harm is caused to product.It is quiet with resisting
The increasingly extensive application of electric agent also proposed increasingly higher demands to the performance of antistatic agent.
Plastics are the widely used high molecular synthetic materials of modern society, it have very high surface resistivity (25 DEG C,
RH60%, resistivity 1017Ω).Thus, once be charged by friction, electrostatic not easily passs through conductive remove and is trapped in frosting.
Due to the presence of electrostatic, not only influence the beauty (dust suction etc.) of plastic products, more important is the manufacture for influencing plastic products and
It uses.Plastics package antistatic agent reduces Polymer Surface resistivity and charge density for plastic products face, to reach solution
Destatic the purpose of harm.
Traditional antistatic agent is made of the surfactant of small molecule, it contains hydrophilic radical and lipophilic group.By
It is not exclusively compatible in it and resin itself, therefore antistatic agent can be from resin internal migration to resin surface.It is traditional antistatic
Agent needs can act below certain damp condition, and hydrophilic radical can promote frosting to be readily wetted by water, to dredge
Electrostatic charge reduces the surface resistivity of plastics.Only can just it work after conventional antistatic agents molecular migration is to surface, plastics
Internal antistatic agent molecule moves about to surface, until completely consume, thus its function and effect is only in certain time model
It encloses interior effective.
Macromolecule permanent antistatic agent can only be added in base-material by the method for mixing.It is not by migrating to modeling
Expect surface, and be positioned against plastics inner and form the Percolation Network with conductive capability, takes off surface and sheet as access
Intracorporal electrostatic charge reduces resistivity.Compared with conventional antistatic agents, antistatic effect is lasting, no induction period, is not wiped
It is influenced with conditions such as washings；Because its electric conductivity reaches not by water layer, thus relies on the relative humidity of air
Property is small, and the mechanical performance and heat resistance of product are unaffected.
CN102051156A discloses a kind of poly-vinegar ethers Polymer-metallic Catalyst, mainly by the original of following parts by weight
Material prepares: 100 parts of poly glycol monomethyl ether metering system vinegar, 30-250 parts of methyl methacrylate vinegar, methacrylic acid
Sodium or methacrylic acid with sodium carbonate mixture 2-50 parts, 1-30 parts and AIBNO.1-5 parts of sodium metasilicate.The invention does not use
Unstable and toxic sodium perchlorate keeps production process more environmentally-friendly, and furthermore the invention also improves the temperature-resistance characteristic of product,
Use scope is expanded, can be applied in the materials such as PET, PA, PB, PE, PP, PS, ABS, PVC, PLA of antistatic.But this is anti-
Electrostatic agent is as most existing usual products, and there is influence the qualities such as plastic product mechanics.
