Abstract
The invention discloses a preparation method for a UV (Ultraviolet) curing organic-inorganic hybridized antistatic coating. The preparation method is that organic functionalized high molecules and anionic inorganic small molecules are mixed with the mass ratio being 1-3:1; deionized water serves as a solvent and is added to be stirred uniformly and the solid content of the solution is 20%; and 0.5%-2% of coupling agents and 0.5%-3% of photoinitiator are added and mixed uniformly through a homogenizer, standing and defoaming are conducted for 1-3 h, and the antistatic coating is obtained. The UV curing organic-inorganic hybridized antistatic coating disclosed by the invention prevents the defects of small antistatic molecule, easiness for transfer, high solubility, poor antistatic property and durability, easiness for decomposition caused by heating and the like, and carries out light curing treatment on a coating by using an organic-inorganic hybridized antistatic agent and adopting a UV curing technology. According to the UV curing organic-inorganic hybridized antistatic coating, the cured coating can not be transferred, so that the antistatic property and the durability are further enhanced.
Description
Technical field
The present invention relates to functional coat technical field, refers specifically to a kind of curing organic-inorganic hybridized antistatic coatings of UV
Preparation method.
Background technology
Macromolecular material is mostly excellent electrical insulating property material, its surface resistivity ρ s (1014～1017Ω) and volume
Electricalresistivityρ v (1015～1018Ω m) it is very big, a large amount of electrostatic charges are easily gathered, so as to hamper production process and product quality, weight
Then cause the accidents such as fire, blast.The antistatic modified method of plastics mainly has two kinds：One is additive process, in non-polar resin
Middle addition antistatic additive, the antistatic behaviour for making plastics is improved, the property of the amount of filler and processing technology of addition to resulting materials
Can affect very big；Two is surface method, i.e., to surface of plastic products using methods such as plating, coating, stickups so as to product surface shape
Into conductive layer.The high cost of plating, it is difficult to process complex-shaped product；Cladding process is usually to match somebody with somebody effective antistatic ingredient
Water or alcoholic solution, i.e. antistatic coating are made, surface of plastic products is processed by methods such as dipping, spraying or brushings, it is subsequently dry
Dry desolvation is obtained with anlistatig film, and the method has consumption few, easy to process, does not affect material internal performance
Feature.
Antistatic coating is that have functional coat that is conductive and excluding accumulation electrostatic charge ability.Antistatic coating is used as work(
Energy property coating, its surface resistivity is generally 105～109Ω, it is possible to use the effect of releasing of electrostatic, will accumulate in body surface
Electrostatic charge release in time, so as to reach anlistatig good result, it is to avoid the various problems caused by accumulation of static electricity, therefore extensively
It is general to be applied to various industrial circles such as electronics, electrical equipment, aviation, chemical industry, printing.
Conventional antistatic additive is small molecule antistatic additive, but due to small molecule antistatic additive molecular weight it is little, easily migration, molten
Xie Xing great, antistatic behaviour poor durability, easily decomposition of being heated, tend not to reach preferable antistatic effect.
The content of the invention
The technical problem to be solved is for the deficiencies in the prior art, there is provided a kind of UV curing organic-inorganics
The preparation method of hydridization antistatic coating.
To achieve these goals, the preparation of the curing organic-inorganic hybridized antistatic coatings of a kind of UV of the present invention
Method, the method is by functional organic macromoleculeWith anionic inorganic small molecule Ti
(OEt)4With quality as 1-3:1 ratio mixing, adds deionized water uniform as stirring solvent, makes the solution solid content be
20%, the coupling agent of 0.5-2% and the light trigger of 0.5-3% are added, Jing after high speed agitator is well mixed, stand froth breaking
1-3h, obtains final product antistatic coating.
Optimally, the high molecular chemical constitution of described functional organic isWherein n is
30～200.
Optimally, described light trigger is benzophenone or 2- hydroxy-2-methyl -1- phenyl -1- acetone；Coupling agent is
Silane coupler.
Optimally, described functional organic macromoleculeWith anionic inorganic small molecule
Ti(OEt)4Compatible state is reached by covalent bond using coupling agent.
The antistatic coating is UV solidifications, the antistatic painting of hybrid inorganic-organic prepared by sol-gal process
Layer；Contain light trigger in described antistatic coating, and cross-linked structure is obtained by UV solidifications, wherein light trigger is
BenzophenoneOr 2- hydroxy-2-methyl -1- phenyl -1- acetone
The beneficial effects of the present invention is：
Compared with prior art, the curing organic-inorganic hybridized antistatic coatings of new UV of the present invention avoid small molecule
It is antistatic to resist big easy migration, dissolubility, antistatic behaviour poor durability, the drawbacks such as easy decomposition of being heated, resisted using hybrid inorganic-organic
Electrostatic agent, while carrying out photocuring process to coating using UV curing technologies, the coating after solidification is not migrated, antistatic behaviour
Further improve with durability.
