Description
Technical field
The present invention relates to field of organic polymer compound, relate to and only use carbon-carbon double bond macromolecular compound, be specifically related to UV cured resin.
Background technology
In recent years, along with developing rapidly of precise electronic and precision equipment industry, for some sensitive electron original papers, chip, the production environment of the products such as precision instrumentation was very strict with the requirement of wrapping material.For common plastics sheet material, due to the high impedance insulator characteristic of plastics, under friction or sensed conditions, easily produce electrostatic.When a large amount of accumulation, easily there is electrion in electrostatic, thus infringement precision equipment.Meanwhile, due to the adsorption of electrostatic, thus cause dust to be assembled at plastic basis material, cause cleanliness factor to decline, and then the production of interference product, also can affect quality product simultaneously.
In order to reduce and reduce the harm that electrostatic brings, usually adopt the method reducing coated material surface resistivity to increase the electroconductibility of material surface, thus obtain anlistatig effect.Usual method has following three kinds: the resin of (1) existing conducting function is film forming matter, and coating does not generally add other conductive filler materials; (2) add conductive filler material, produce electroconductibility by contacting with each other of conductive filler material; (3) add Antistatic surface promoting agent, rely on the electrostatic in the continuous release coat of Antistatic surface promoting agent, reach the object of anti-electrostatic.Although aforesaid method plays anlistatig effect to a certain extent, due to the synthesis difficulty of electroconductive resin, and cost intensive; The method of adding conductive filler material is subject to factors as the impact of cost etc., and coating property is also unstable simultaneously; So they are not gratifying solutions all the time.Add Antistatic surface promoting agent and there is simple process, the feature that cost is low, be generally considered to the effective ways in antistatic material production.But due to the molecular weight of the tensio-active agent that plays anti-static function, surface transport is serious, thus causes the persistence of antistatic effect and weather resistance all lower, and there is the problem polluted and use other materials contacted.
The mechanism of action on Polymer-metallic Catalyst is had: Polymer-metallic Catalyst is under the impact of special solvent and resin system in paper Synthetic metals139 (2003) 1-10, after comparatively low-shearing power stretching action, form stratiform dispersed texture in the base, thus effectively reduce the resistance of composition coating, and there is the effect of permanent anti-static.CN200610078304 mentions poly-thiophene phenol and derivative thereof because its conjugacy structure, makes its electronics move along molecular chain or molecular chain of jumping over and to have essential conductivity.
Ultraviolet-curing paint, be called for short UV coating, that the cross-linking polymerization producing free radical or positively charged ion and then the oligopolymer caused in coating and reactive thinner molecule in ultraviolet irradiation condition by the light trigger in coating forms film using high-octane UV-light as the solidification energy.Compared to traditional heat curing coating, UV coating has that curing speed is fast, VOC quantity discharged is low, be suitable for the features such as high-speed automated processing; And compared with heat curing coating, UV coating, by the crosslinking polymerization between each component, by liquid fast setting film forming, and has tridimensional network, the coating performance produced is excellent, and hardness, snappiness, wear-resisting scratch-resisting, chemical proofing, high glossiness, wearing quality etc. are improved.Especially, what utilize due to solidification process is the energy of UV-light, and reaction can be carried out at normal temperature or lower than when normal temperature, does not need high-temperature heating process, so be suitable for very much the processing on the thermo-responsive plastic basis material surface such as PET, PP, PMMA, PC.
But, because poly-thiophene phenol is the superpolymer that a class relative molecular weight is larger, therefore the consistency of it and UV resin is poor, causes the paint stability prepared by it poor, in coating solidification process, produce foreign matter point and send out the problem such as mist, affecting the performances such as the outward appearance of product and transmittance; Simultaneously, because photo-cured coating is compared with water-borne coatings than traditional solvent reducible coatings, have finer and close tridimensional network, macromole static inhibitor is not easy the surface moving to coating, affect the antistatic property of product, because which limit the application of poly-thiophene phenol in photo-cured coating.
